14 TRENCHLESS AUSTRALASIA FEBRUARY 2022

t is my pleasure to welcome you to the No-Dig Down Under 2022 edition of Trenchless Australasia. It has taken us slightly longer to get here this year, with the ongoing COVID-19 pandemic disrupting our plans for the 2021 event. However, I am pleased to see so many of you in person after three years apart. I can’t wait to catch up with everyone. Thank you to our sponsors and exhibitors for continuing to believe in the vision of No-Dig Down Under, and supporting the event through a postponement. Looking at the quality of displays we have planned for this year, I can say with certainty – it was worth the wait. As Australia’s only dedicated exhibition and conference for trenchless technology, this event is incredibly important for our industry. To all our exhibitors – thank you for showcasing your latest innovations and how you are directly contribute to the advancement of our industry. I am looking forward to speaking with you all and finding out more about what you have been up to over the past three years. Without your support, No-Dig Down Under would not be possible. This event is the one place where we

can see all the advancements in technology solutions from suppliers and meet with our peers in one spot. I for one, find each No-Dig Down Under event more inspiring than the last, and I’m sure this edition will be no exception. I am proud that our industry has continued to thrive throughout the pandemic, with many individuals and companies in the room contributing to Australia’s – and indeed, the world’s – ongoing major infrastructure projects. I hope you all give yourselves a pat on the back for a job well done over the course of the past few years. It has been tough, but I am grateful that we have made it to the other side. Of course, this event wouldn’t be the same without the support of Gold Sponsor of No-Dig Down Under, Herrenknecht. With tunnelling projects right across Australia and New Zealand, Herrenknecht is proving critical to some of the most important infrastructure projects in the Oceania region. I think it is a testament to the strength and importance of this event that we have companies such as yours supporting it. Ben Crosby ASTT President

NEWS IN BRIEF

City Rail Link Tunnel Boring Machine (TBM) Dame Whina Cooper broke through into Aotea station marking the end of its epic underground journey from Mt Eden.

METRONET The METRONET project has moved into its final stages, with works on the Thornie-Cockburn line progressing swiftly. Tunnel boring machines ‘Jana’, ‘Grace’ and ‘Sandy’ began constructing underground tunnels for the METRONET project back in August. Work is now well underway to install the new rail tracks with more than five kilometres to be laid by the end of the shutdown. The Thornlie-Cockburn Link will be Perth’s first east-west cross line connection, making travel around the city by train more flexible and providing a higher level of public transport service to Perth’s southern suburbs.

Significant progress has been made on the City Rail Link (CRL) - a 3.45 km twin-tunnel underground rail link up to 42 m below Auckland’s city centre and the country’s largest transport infrastructure project. Just prior to Christmas, workers began removing the final pieces of wall to connect the new Aotea Station to the twin tunnels running from Britomart Station. The breakthrough under the intersection of Albert and Wyndham Streets joins the twin tunnels completed in early 2020. Tunnel boring machine (TBM) Dame Whina Cooper also broke through into Aotea Station after its seven-month journey cutting into the earth and removing spoil to the surface. This breakthrough was the final link in the first of two tunnels running 3.45 km of link between Mt Eden and Britomart.

Works on METRONET’s Thornie-Cockburn line are progressing swiftly.

Central Interceptor Watercare coastal walkway in Mangere, South Auckland.

Watercare’s NZD$1.2 billion ($1.14 billion) Central Interceptor wastewater project has achieved some significant milestones, with micro-tunnel boring machine (mTBM) ‘Domenica’ completing its first drive, successfully breaking through at the Haycock Ave shaft on 10 December. Domenica was placed in a 2.1 m diameter pipe for the link sewer that will run between Miranda Reserve in Avondale to the main Central Interceptor wastewater tunnel, connecting up at May Rd in Mt Roskill. 18 TRENCHLESS AUSTRALASIA FEBRUARY 2022

Once complete in 2026, the Central Interceptor will store and transport both stormwater and wastewater to Watercare’s Māngere Wastewater Treatment Plant, preventing wet-weather overflows and significantly cleaning up Auckland’s waterways. This was first of many anticipated breakthroughs on the five-year tunnelling project. Meanwhile, Central Interceptor’s main mTBM Hiwa-i-te-Rangi is expected to start tunnelling deep beneath the Manukau Harbour this year.

NEWS IN BRIEF

Warkworth wastewater scheme Watercare is currently tunnelling more than 5 km of new pipeline from Lucy Moore Memorial Park to a new wastewater treatment plant in Snells Beach.

Watercare is currently tunnelling more than 5 km of new pipeline from Lucy Moore Memorial Park to a new wastewater treatment plant in Snells Beach, North Auckland. Watercare anticipates construction work on the pipeline and wastewater treatment plant will start early this year, while works on the $26 million pump station in Lucy Moore Park are already underway.

Tunnelling will be carried out deep underground (between 30 and 40 m) by direct pipe tunnelling — a method that was successfully deployed on the Snells-Algies wastewater outfall. This project set the world record for the longest direct pipe drive by a mTBM, reaching 2021 m – a whole 92 m further than the previous record set by McConnell Dowell in 2018. The Warkworth wastewater scheme is expected to be completed in 2024.

COVER STORY

New adaptable machines shake up HDD market TRACTO-TECHNIK’s new and revolutionary range of horizontal directional drilling (HDD) rigs have landed in Australia.

RACTO’s products are constantly being refined based on end user feedback, and the new range of GRUNDODRILL fluid-assisted and rock drilling machines are the ultimate reflection of this ideology. Consisting of six machines with performance ratings between 60 and 280 kN, the rigs in the new range can be adapted to be used as a Jet Condition System (JCS) for excavating in conventional soils with normal rods, or as an All Condition System (ACS) using twin-tube rods to navigate through rock. Tailored to the end user The customisable and adaptable nature of the machines is the result of years of research and development at TRACTO’s headquarters in Lennestadt, Germany, where the machines are also manufactured, using best-in-class processes

The new 130ACS, equipped for drilling through hard rock, operating on site.

and materials, before being shipped around the world, including to Australia and New Zealand. The design keeps the complex and unique demands of the HDD process front of mind, and has culminated in drills with unparalleled adaptability, versatility and efficiency in the market today. As a result of the modular design, the GRUNDODRILLs can be configured to the specifications or restrictions of the market in which they’re operating. This includes 40 options for customisation according to application and comfort. Autonomy The majority of all rig functions are controlled via a centralised touch screen and monitored via an integrated camera, which can be tailored to the needs of the operator.

This enables ergonomic conditions for the user, limits fatigue and frees them up to focus on the task at hand: drilling. Remote-controlled drilling is also possible with the new machines, with operations conveniently controlled and monitored from outside the operator’s cabin using a specially designed remote-control unit. In combination with an intelligent camera, this allows for the full control of the entire drilling rig. The 130JCS/ACS features a Cummins Tier V engine, equipped with variable torque and speed adjustment for maximum rotational performance and maximum productivity. In addition, the machines are capable of fully automatic drilling operations, including drill rod exchange. In addition to this performance and customisation, the machines can also be

equipped with a range of high capacity mixing systems, meaning they can operate for longer periods without disruption. More than a dealer Not only are these revolutionary machines the best available on the market, according to TRACTO, they are also supported by the best servicing, spare parts and training the industry has to offer. The company has recently

positioned itself as “more than a dealer” with the goal of creating and maintaining meaningful and lasting relationships with its clients. This includes guiding customers through all stages of the product process, from purchase to training and after-sales support, as well as giving clients access to technical and engineering support in real time. TRACTO Australia Managing Director Jeff Rose says there’s an appetite from the

trenchless industry for the adaptability and performance of the new machines. “The design has been meticulously planned for a number of years. During this time, all the feedback and responses from our clients in Australian and New Zealand, as well as all over the world, have been fed back to our German engineers for consideration,” he says. “While the conditions for HDD might change from region to region, the challenges for contractors are ubiquitous. With the 130JCS/ACS range, we’ve delivered machines which address those challenges, providing the adaptability, power and performance to increase drilling efficiency and optimisation.” A GRUNDODRILL 130ACS has already been delivered to a customer in Australia, with Victorian-based trenchless contractor R&R McClure taking delivery of a machine in early 2022. The machine is setup to excavate through the tough quartz-rock which is unique to the Castlemaine and Bendigo region where the contactor is based. One of the new GRUNDODRILLs will be on TRACTO’s stand at No-Dig Down Under, giving contractors the opportunity to see the machine and its features up close.

Digging Deep: major infrastructure works in the pipeline for NSW It has been an interesting time for the trenchless industry in New South Wales. In a post-COVID economy, Australian governments have committed funding to an unprecedented wave of infrastructure investment across transport, utilities and social infrastructure to stimulate economic recovery, and New South Wales is no exception.

ccording to Infrastructure Australia, an investment of more than $290 billion has already been planned across the country in the construction sector. NSW has major trenchless works in the pipeline for projects across water, hydrogen and hydroelectricity, some of which are already underway. Water Corporation general manager of assets planning and delivery Evan Hambleton said that by proactively replacing these assets, the utility could safeguard against future leaks and bursts, in turn helping to avoid unplanned interruptions. Water With the reality of climate change now sinking in and a growing need for climate-independent water sources, states are investing in better water security with the construction of new storage facilities and upgrades to old, leaky pipelines. The NSW Connections package is being rolled out, which includes the construction and upgrade of water infrastructure. The package aims to expand the state’s agricultural industries, as well as provide adequate water supplies and address storage and quality issues. Jointly funded by the Federal ($15. 8 million) and NSW Government ($24.3 million), the package consists of five projects: Lake Wyangan Water Sustainability project, Walcha Off-Stream Water Storage, West Wyalong Water Reliability project, Broken Hill to Menindee Graziers Pipeline and Urbenville Water Supply project. According to NSW Minister for Water Melinda Pavey, once completed, the package will deliver 1650 megalitres in additional storage capacity as well as 4380 megalitres per annum increased water availability. “This will mean more than 240 hectares of additional land will now be open to irrigation, and nearly 200 new customers or properties will be able to connect to the improved water supply delivered by this suite of projects,” Minister Pavey says. All projects are expected to be completed by mid-2023. Hydrogen Following the 26th United Nations Climate Change conference (COP26) last October-November, there has been a huge investment in hydrogen and its associated infrastructure nation-wide. As a clean but volatile gas, hydrogen generates zero carbon but requires specialist infrastructure to be distributed throughout gas networks. Australia’s National Hydrogen Strategy is a plan to grow this industry and position Australia as a major player by 2030. In his first major cabinet decision as Premier in October, Dominic Perrottet signed off on Australia’s largest hydrogen strategy. The industry will require large scale electrolyses, renewable electricity, water and water pipelines, electricity infrastructure and hydrogen pipelines in order to successfully integrate into our existing network. Existing pipelines will be redeployed and relined for alternative delivery outside of natural gas. 24 TRENCHLESS AUSTRALASIA FEBRUARY 2022

Companies like Baker Hughes and Primus Line are already collaborating on the development of a non-metallic composite pipe application to repurpose existing pipelines for hydrogen and CO2 transportation, having signed a memorandum of understanding (MOU) in October. Hydroelectricity In December, Snowy Hydro began assembling a giant tunnel boring machine (TBM) in preparation for the excavation of a 16 km headache tunnel for the Snowy 2.0 project. Snowy 2.0 is a renewable energy project that will provide on-demand energy and large-scale storage in the Snowy Mountains, New South Wales. It is the largest committed renewable energy project in Australia that will underpin the nation’s transition to a low-carbon future. The project involves the development of a new underground power station around 1 km below ground, as well as the linking of two existing dams – Tantangara and Talbingo – through 27 km of tunnels. Hydroelectricity is generated when falling water spins giant turbines. Water will be pumped to the upper dam where there is surplus renewable energy production, and then released back into the lower dam to generate energy. Snowy 2.0 will provide flexible, on-demand power while recycling the water in a closed loop and maximise the efficiency of renewables by using excess solar and wind energy to pump water to the higher dam, to be stored for later use. Company Snowy Hydro is leading the project and has begun assembling a giant TBM ‘Florence’ ready to excavate a 16 km headrace tunnel. Most of the 27 km of tunnel on the project will be excavated by TBM, with the concrete segment-lined tunnels reaching 10m in diameter. The company achieved another exciting milestone in December with the commissioning of a second TBM. The 11 m diameter TBM ‘Kirsten’ is one of three TBMs that will excavate the tunnels for the pumped-hydro expansion. Snowy Hydro chief executive Paul Broad said Snowy 2.0 was creating 4,000 jobs and significant training and apprenticeship opportunities for workers, while providing a major economic boost for the Snowy Mountains region and beyond.

RELINING

McRobert completes access chamber refurbishments in the Northern Territory McRobert Contracting Services is an Australian-owned and operated industry leader in the refurbishment of underground assets and polyvinyl chloride (PVC) pipeline technology. Operating since 1988, this Perth-based company has more than 30 years and nine patents behind it.

CS has developed a patented method for structurally relining access chambers that have suffered from sulphide corrosion, more commonly known as gas attack or concrete cancer. Using 10 mm rigid PVC sheeting, the chamber walls are prefabricated into sleeves, which can then be lowered directly into the asset. After installation, the preformed sleeves are secured to the original asset using a minimum 40 mm of high-strength grout. The grout not only secures the lining in place; it also rebuilds the concrete that has been depleted. The grout then rebuilds the internal concrete surface and ensures that structural integrity is maintained, while the rigid PVC provides

corrosion protection to the asset. McRoberts’ refurbishment systems are equivalent to less than 20 per cent of the cost of replacement and carry a minimum 50-year guarantee. Furthermore, the peak body representing Australian water utilities - the Water Services Association of Australia (WSAA) - has appraised the use of PVC pressure and nonpressure pipe products as fit for purpose with a life expectancy of more than 100 years. MCS recently completed a large project in the remote community of Amoonguna in the Northern Territory for client Power and Water Corporation, NT. The company carried out the structural refurbishment relining of 26 access chambers using its patented

relining method, with 15 more scheduled for relining this year. The Amoonguna community sewer reticulation access chambers were around 40 years old, having been installed in 1981. According to Power and Water Corp, McRobert’s method as it was the most viable option to extend the life of the assets up to 50 years, coming in at a third of the cost of new chambers. These refurbishments were completed in less than six months and have been stamped with the company’s 50-year guarantee. For more information visit www. mcrobertcontracting.com.au/

INSPECTION & CONDITION ASSESSMENT

VAPAR provides CCTV solutions to asset managers 2021 has seen the continued uptake of new technology that unlocks efficiencies for engineers who manage sewer and stormwater pipe networks. Cloud-storage, cataloguing of inspections, thematic mapping, improved decision-making workflows and reduced backlogs are just some of the benefits the VAPAR Solutions platform is bringing to the sector.

void the backlog A common industry challenge is how to effectively manage the increasing volume of CCTV pipe inspection data that accumulates over time. Backlogs occur when inspection projects reach completion, but the packaging of the subsequent required programmed work is delayed. A CCTV backlog can then grow larger when the pace of condition inspections continues at a faster pace than the review and decision process. This dilemma is often exacerbated by resource challenges where engineers are spread thinly across multiple asset management tasks, and when efficient data access is not in place to support the decision-making process. The receival of CCTV inspection results should not be considered the final delivery of a program, but rather a point in the circular process of pipe asset management. Each step should be designed to synchronise and complement the one that follows.

Acquiring the 1 to 5 condition gradings is only one part of managing a pipe network. Questions to consider when implementing a successful asset management strategy include: • Do I have confidence that I’m inspecting the right percentage of my network, and the correct pipes within it? • Do all relevant stakeholders in my 28 TRENCHLESS AUSTRALASIA FEBRUARY 2022

organisation have access to data from past inspections? • Am I updating my GIS and asset management systems with condition results? • Is my process designed to inform asset risk, value, and future inspection programs?

No silos in the cloud Having a suitable storage option for the large amount of video files that CCTV inspections generate, while retaining access for stakeholders to view reports and make maintenance and rehabilitation decisions, presents both storage and software challenges for councils and utilities. Greater Western Water (Victoria) and

Richmond Valley Council (NSW) are two such organisations that have turned to the VAPAR. Solutions platform to significantly improve the access and management of their inspection file libraries covering the last five years. Moving to a cloud-based solution provides options to keep both GIS mapping and asset management systems up to date, while removing the reliance on portable hard-drives and messy network folder structures that can lead to data silos and unintended information barriers. Same storage for pushrod and zoom footage Traditional CCTV pipe inspection software and processes have been designed to work with pan-tilt-zoom crawler cameras. This often leads to inspections collected using pushrod and polemounted zoom cameras being poorly catalogued and lacking a common approach to access and compare condition information. In many cases, a video is captured but soon after the footage and data disappear due to poor storage and reporting options. 2021 saw VAPAR successfully run projects that provided the opportunity to import, analyse and produce inspection style reports for a range of camera hardware. The opportunity to store, map, report, and track decisions for crawler, pushrod, and pole camera inspections all in the one location has significantly increased the

value and useability of this type of footage for asset owners. Having access to more condition collection methods allows for greater flexibility and increased coverage of a network to better manage risk and improve the understanding of pipe infrastructure. Mildura Rural City Council sought options to economically survey a significant percentage of their stormwater network that would provide condition data to inform their operational and capital works programs. They recently engaged Interflow, a VAPAR Partner, to complete this package of inspection works using pole-mounted zoom cameras with results available directly through VAPAR’s browser

platform. This has seen the value and detail of the collected data increase with better access to videos, images, condition results, and inspection reports. This data is formatted to import directly to GIS for thematic mapping and broader user access. Over 80km of inspections are scheduled to be completed during this project. VAPAR began the new year processing footage for Muswellbrook Shire Council, with inspections completed by Mullane, a Central Coast / Hunter based VAPAR Partner. Some of the earliest of adopters of advancing technology for the CCTV pipe condition assessment process have been rural and regional councils. One of the primary influences for this trend has been the demand for engineers and project managers to spend less of their time watching videos and become more focused on managing pipe risk. Understanding this risk using targeted defect frames and open data presentation has been designed to make the pipe condition assessment workflow smarter with improved outcomes. Gunnedah Shire Council have a large inspection program that began in January. Michael Ludlow (Project Manager Water Services) explains some of the reasons that led to new solutions for managing their sewer network. “We were looking for an innovative solution

that could evaluate CCTV footage and give an accurate assessment of our sewer infrastructure that took the human factor out of the evaluation process, Council required VAPAR to be able to integrate with CCTV contractors to give us the best possible result that was accurate and cost effective we believe that VAPAR ticked all those boxes.” Regional councils aren’t alone in realising the benefits of VAPAR’s new technology. In Sydney, both Blacktown City Council and Campbelltown City Council have adopted VAPAR to drive improvements in workflow and decision-making. Campbelltown is one of the faster growing areas in Sydney and have found that VAPAR’s AI processing and data outputs don’t just improve their condition assessment program. They now use VAPAR Solutions as part of their new pipe acceptance and end of warranty testing. This has enabled them to reduce the turn-around time from weeks to days. Implementing iterative machine-learning updates to the AI processing engine and the further development of automated solutions, VAPAR continues to roll-out this advanced technology to councils and utilities in 2022.

MICROTUNNELLING

Continuing the legacy Pezzimenti Trenchless continues to deliver top-notch results for Victoria’s leading sewer and water contractors, with 2022 set to be a year of developing equipment to further support its growth.

ezzimenti Trenchless, now a thirdgeneration family business, was incorporated in 2011 by Joe, Anthony and Stephen Pezzimenti as part of a family succession plan. Managing director Joe Pezzimenti says he joined the family-run Pezzimenti Laserbore in 1989, followed by Anthony in 1995 and Stephen in 1997. The company uses its own Pezzimentideveloped laser-guided micro tunnelling systems and specialises in free boring, sleeve boring and pipe jacking methods. “We use laser-guided microtunnelling that involves vacuum extraction for the most effective and efficient method of installing new services for the sewer, water, drainage, gas and telecommunications, along with vacuum-loading and non-destructive digging services, using our state-of-the-art vacuum units,” says Pezzimenti. Pezzimenti says the company offers unparalleled expertise and technology to provide clients with the best solution for

their projects, whatever size. “From gas and water lines to new constructions and the latest telecommunications installations, our seven crews located throughout Victoria and South Australia work to service our clients’ needs, equipped with the latest technology and decades of experience and expertise.” The company was recently sub-contracted to complete the Ravenhall Outfall Sewer works, a project issued by Califam Constructions and Greater Western Water, to construct 894 metres of DN900 mm branch sewer and 181 metres of DN225 mm reticulation sewer as part of the development works on Palm Springs Rd, Ravenhall in the City of Melton. With nearby road crossings, some parts of the project had to use a microtunnelling method to bore under the road crossing. “We were engaged by Califam Constructions to undertake two sections of microtunnelling where open cut, a method of pipeline installation that requires opening up the surface

of the ground, wasn’t an option, being under two major roads,” Pezzimenti says. Pezzimenti Trenchless utilised the free boring method to drill directly into an existing manhole without requiring a retrieval shaft, which was a major advantage of its free bore method. Pezzimenti says free boring offers an ideal way to install services utilising conventional pipes. In cohesive, stable clays, mudstone and rock, free boring is the most economical method of service installation as conventional pipes can be inserted into the bore. Pezzimenti says he’s eager to put COVID-19 behind him and looks forward to the year ahead by adding another crew to the ranks this year and getting a better foothold in the South Australian market. Pezzimenti says the company has grown its capabilities to tackle more challenging jobs, and that its major focus has been on developing its equipment to tackle basalt ground conditions. “When you work with Pezzimenti Trenchless, you are accessing the very latest in technological developments.”

Powering through the challenges of the Pilbara Horizontal directional drilling provides many challenges at the best of times. In urban centres, drillers are faced with limited space and machinery access, while noise limitations and environmental integrity have to be strongly observed. The combination provides powerful downhole cutting action and the flexibility to select the appropriate tooling to best match the ground conditions, which can allow the entire install to be completed with one machine.

The Vermeer D40x55DR S3 Navigator® was chosen for its proven ability to provide excellent productivity across a broad range of ground conditions.

egional projects also present their unique challenges as the teams at Streamline Connect and Vermeer Equipment of WA & NT recently discovered.

Operator comfort and safety were also a major factor in choosing the right machine to do the job – with temperatures in the region regularly exceeding 40 degrees Celsius.

Working through varying ground conditions and challenges In late 2021, Streamline Connect was appointed by a leading mining company to lay over 140 kilometres of optic fibre cable alongside a railway track in the Pilbara region of WA. This work included over 4500 m of directional drilling. The project also presents many obstacles to overcome along the way – including roads, railway crossings, creeks and rivers. The project required drilling across varying depths, as well as around some tight obstacles. Hard igneous granite and basalt rock along the drill path also present additional challenges for the project.

One machine, one practical solution Streamline Connect required a horizontal directional drill that was tough enough to tackle hard rock, yet nimble enough to provide exceptional steering and turns. Working closely with the team at Vermeer Equipment of WA & NT, the Vermeer D40x55DR S3 Navigator® horizontal directional drill was chosen for the job for its proven ability to provide excellent productivity across a broad range of ground conditions, from hard, medium, and soft rock, to loamy dirt and clay. This rock drill features dual rod technology that uses an inner rod to provide torque to the drill bit, while the outer rod offers steering capability and rotational torque for reaming.

Streamline Connect required a horizontal directional drill that was tough enough to tackle hard rock resulting in it working closely with Vermeer Equipment of WA & NT.

Impressive results Utilising the Vermeer D40x55DR S3, the team at Streamline Connect are on target to produce its contracted bore amount. “With 150 metres of drill rod on-board the Vermeer unit, every day is a productive day,” says Streamline Connect Operations Manager Andrew Angelatos. “Recently we did hit granite! That’s when we knew we chose the right machine, powering through rock, where other machines would struggle. We found that the drill has more than enough power for the tough jobs.” Powered by a 140 hp (104 kW) John Deere diesel engine, the Vermeer D40x55DR S3 serves up 40,000 lb (177.9 kN) of thrust/pullback and 5,500 ft-lb (7,457 Nm) of rotational torque. Keeping the crew safe and productive “As we were operating in hot and dusty conditions, keeping our drilling crew safe and productive also played an important part in the machine we chose. The cabin and rod loading features of the Vermeer unit certainly proved its worth, with our operators working safely and in comfort,” Angelatos says. The Vermeer D40x55DR S3 offers drillers climate control, weatherproofing and reduced noise levels of 80 dBA at the operator’s ear, in a standard cab configuration. The time and steps required to add or remove a rod on the D40x55DR S3 is significantly less due to an enhanced dual drill rod design that quickly and easily makes up the inner and outer rod connections.

try to ensure we have the tools that drillers will need, when they need it. Our on-hand inventory is always well stocked. “Because we’re backed by 23 years of dealing with drillers, we’ve been able to adjust and improve the way we manage our stock, so we can get it to the contractor in a timely manner.” The company even set up a secondary location in Melbourne, “to kill transit for the guys down south,” Spaninks says. “We’re able to cover that whole east coast and south area really well.” Since the outbreak of the COVID-19 pandemic, the team at QDS has had to change the way it manages on-hand stock due to massive delays in logistics and freight. “The cost of raw materials and manufacturing has gone up substantially, so we’ve had to shift our forecasting and expand our inventory,” says Spaninks. “We now prepare a good six to eight months in advance, as we have to preempt these time delays. “Thankfully, due to the great relationships we have with our suppliers, they allow us to hold more stock with extended terms, so we’re able to order more at once to prevent any shortfall.” The employees at QDS are trained to have a wide breadth and depth of knowledge on solutions for a range of jobs with variables including size, budget, job type and ground conditions. Whether it’s hire equipment or custom-built tooling and repairs, QDS offers all the best quality suppliers in the business at the most competitive prices. Working with its customers to deliver a broad range of outcomes across both locations in Queensland and Victoria, QDS is committed to helping a diversity of contractors to fulfill their drilling needs.

Case study QDS recently worked with long-time client DirectBor, a Geelong-based boring and drilling contractor, to supply the business with a new recycler unit. Elgin Separation Solutions pioneered the packaged mud recycling system decades ago. QDS selected the Elgin Tango 400HD2™ for its highest-rated hydraulic cleaning capacity in its class, at an impressive 400 gallons per minute (25 lps). Traditional systems offer single-pass

cleaning, while the Elgin Tango 400HD2™ features a multi-pass configuration, allowing each cut to be returned to the primary tank for continuous recirculation. This feature maximises the shaker and hydrocyclone cleaning performance. After supplying DirectBor with the Elgin Tango 400HD2 on their recent project in Gheringhap, Victoria, DirectBor director Aaron Finch praised the QDS team for their expert knowledge of HDD inventory and exceptional service. “Craig (QDS sales manager) has been a godsend: always available, and an encyclopaedia of knowledge, delivering fast and effortless service and support,” said Finch. “[The Tango 400HD2] has been a game changer for us; I only wish we’d discovered it sooner. Now it’s the backbone of our entire operation.” Finch said the unit has reduced his cost in dumping, as he’s been able to go from three to four vac trucks onsite to just one machine. Supporting the load of three rigs, it is also simple to operate with high functionality, which means DirectBor can crank mud at an unprecedented rate.

Rob Carr gearing up to deliver major projects in 2022 Leading microtunnelling contractor Rob Carr is preparing for one of the company’s busiest years, with multiple major projects at various stages taking place in different states.

or almost 30 years, Rob Carr has been a leader and pioneer of microtunnelling for the design and construction of utility infrastructure projects in the water, energy and transport space. Having previously constructed some of Australasia’s most complex pipe jacking projects, this year the company will be busier than ever working on multiple significant projects in Western Australia, New South Wales, Victoria and Queensland. Quinns Main Sewer Extension, Perth Rob Carr was awarded a contract to deliver the Quinns Main Sewer Extension for Water Corporation in Western Australia in 2021. The design and construct contract – which is one of the biggest projects the contractor has undertaken in WA – will extend the Quinns Main Sewer to the Alkimos wastewater treatment plant. The pipeline will allow for the conveyance of wastewater flows from Ellenbrook and will run through Clarkson and Neerabup National Park. Following the first stage of the project, which was completed more than 10 years ago, this extension will add approximately 2 km of new 1,800 mm diameter sewer, as well as the construction of six new sewer access chambers and two new vortex chambers. Rob Carr is preparing to start microtunnelling in early April and construction is expected to be completed in February 2023. The contractor will utilise one of its most recent fleet acquisitions, a Herrenknecht Rob Carr’s newly acquired Herrenknecht AVN machine in Germany before it was shipped to Perth for Water Corporation’s Quinns Main Sewer Extension.

microtunnel boring machine (MTBM) to complete the DN1800 pipeline works. A ceremony will be held with community groups where the new MTBM will be named before beginning the main tunnelling activity. Elizabeth Street Sewer Upgrade, Melbourne In November 2021, Rob Carr was awarded the design and construct contract for the next stage of Greater Western Water’s CBD Sewer Augmentation Project focused on Elizabeth Street in the centre of Melbourne. The new contract follows the contractor’s successful delivery of the project’s previous package of work on the adjacent Lonsdale Street. This is the third of four stages of the utility’s $80 million program and will see a new pipeline constructed, linking to the new sewers, under Lonsdale and Spencer Streets. The 723 m pipeline will be formed from OD 820 glass reinforced pipe (GRP) installed via microtunnelling between 6 m and 9 m below Elizabeth Street. In addition, eight GRP manholes will also be constructed along the route. The project is currently in the design phase, with early works having started to locate, identify and relocate existing utility services along the route of the new pipeline, where required. Major construction work is expected to begin in the coming months with completion due early 2023.

ECI and partner projects in the works Rob Carr is currently engaged in multiple Early Contractor Involvement (ECI) processes with major asset owners requiring the installation of important drainage and wastewater infrastructure in NSW, QLD and VIC. The company has also partnered with key Tier 1 and 2 contractors in each of these states for other targeted projects, and remains hopeful of several major project awards throughout the year. More information on each of these projects will be featured in Trenchless Australasia in 2022 once the winning consortiums have been publicised. Rob Carr General Manager Angelo Soumboulidis says the company is excited about what will be a busy year for the company. “All are important large scale projects, so we’re thrilled that our current and prospective clients have the requisite faith in our ability to deliver such major infrastructure upgrades,” he says. “Each project comes with its own unique complexities, constrained working environments and timelines. Whether we are delivering major assets beneath major transport assets, working in a highly constrained CBD working environment or constructing record breaking drive lengths, we aim to provide clients with surety in complex drainage and wastewater infrastructure delivery.” For more information about Rob Carr visit www.robcarr.com.au

When the going gets tuff, the tuff gets pulverised – Southern Hemisphere’s newest Pipe Jacking Record By Ed Ayre, Site Senior Executive, McConnell Dowell In 2007, McConnell Dowell broke a New Zealand and Southern Hemisphere pipe jacking record on the Christchurch Ocean Outfall by tunnelling a single drive of 874 m. While McConnell Dowell exceeded that record in Australia in 2011 with 1050 m on the Northern Pipeline Interconnector, why stop there. In June 2020 the McConnell Dowell Team on Hunua 4 Section 11 Watermain Project in Auckland set new industry benchmarks, and bettered these again in November 2020, just five months later.

n conquering highly challenging basalt and tuff ground conditions, the Team completed 2.9km of pipe jacking over three separate single drives of 389m, 1216m and 1296m respectively, setting microtunnelling records (twice) for: New Zealand’s longest single pipe jacking drive; a southern hemisphere record for the longest single pipe jacking drive by a TBM greater than 2.6m outer diameter; and (to the best of our knowledge), the longest single drive length, large diameter pipe jacked tunnel through continuous hard rock conditions globally.

Future-proofing Auckland’s water supply

Hunua 4 is a 31km watermain stretching from Manukau to central Auckland, delivered by Watercare to improve the capacity and resilience of Auckland’s water network. Named after the Hunua Ranges and the source of the water, the Hunua 4 pipeline will make the network more resilient and cater for future growth. Construction of the pipeline started in 2008 with the crossing of the Manukau Harbour as part of construction of a new motorway bridge, with sections up to Market Road, Epsom now in service. McConnell Dowell was engaged to design and build the final section of the gravity fed watermain to connect the end of the existing pipeline at Market Road to Watercare’s Khyber Pass Reservoir in Grafton. Watercare’s key considerations The proposed alignment for the pipeline started in Epsom, running along Manukau Road then through primarily residential areas before traversing around Mount Eden and crossing the Western Railway line on its route to Watercare Service Reservoirs in Burleigh Street, Grafton at the edge of the CBD. The majority of the 46 TRENCHLESS AUSTRALASIA FEBRUARY 2022

pipeline construction would involve open cut trenching work whilst the section around Mount Eden would require a number of short tunnel drives, shafts and support sites, also within residential areas, and also with associated potential disruption to the local community. “We drew on our extensive tunnelling experience to design a predominantly trenchless alternative over 80 per cent of the alignment which re-routed the pipeline route under the busy arterial Manukau Road and the Southern Motorway (SH1),” advised Stephen Delaney, McConnell Dowell’s North Island Operations Manager. “This moved construction away from residential areas and also mitigated the risk of working on roads, the SH1 and the main trunk rail line.” The tunnelling programme also took the nearby City Rail Link (CRL) project into consideration as it was planned to run

concurrently with Hunua 4 Section 11 nearby in Eden Terrace. By altering the programme to get key works completed before CRL works began the proposal further reduced impacts on traffic, businesses and residents in the area. The challenge - pipe jacking through basalt

Auckland has a unique geology, being built on 50 volcanoes with multiple eruptions and overlapping lava flows, which has given rise to geology consisting of soft ash fall products, volcanic tuff and hard basalt. The majority of the pipeline on other contract sections was completed by contractors using open cut trenches, but having looked at the terrain, alternatives, and the possibility to mitigate significant risks for the client, the team proposed an ambitious alternative - to utilise their Herrenknecht AVN2500 TBM that was

NO-DIG DOWN UNDER 2022 on route to Auckland for the Artillery Road Stormwater Tunnel. The question was - could this TBM be configured to bore through the soft ground near Burleigh Street and Ranfurly Road as well as through the hard basalt and tuff making up the majority of the tunnel alignment? In addition, the optimal alignment would require single pipe jacked drive lengths up to 50 per cent longer than previously achieved in New Zealand. To achieve the preferred alignment S-curves of 750m horizontal radii were required to approach and remain within the road corridors to avoid a need to tunnel under private property. The McConnell Dowell design team worked closely with design consultant McMillen Jacobs Associates (MJA). The list of benefits afforded by the trenchless solution grew and although drives of the

distances proposed hadn’t been done before in these geological conditions - the challenge was accepted, and the team began working on innovative solutions to make it work. Design phase The project was split into two phases – a design package and a construction package. Phase one commenced in January 2017 and involved early planning, environmental impact assessments and completion of detailed design. McConnell Dowell worked with MJA to prepare the detailed

design and the team developed the Assessment of Environmental Effects documentation and the related management plans required to secure resource consent. After completion of the concept and preliminary design work, additional geotechnical investigation was carried out along the revised alignment to enable MJA to complete the detailed design. McConnell Dowell’s in-house engineering team undertook the design for the tunnelling temporary works. The project involved installing

3.7km of pipeline. Five jacking and reception shafts provide access for the TBM - at Khyber Pass Road, Burleigh Street, Ranfurly Road, Clovernook Road and Broadway - and one connection shaft in Edgerley Avenue completes the scope. The three main pipe jack drives ,making up the 2901m of tunnel, in order of construction, were: • The first drive of 389 m from Khyber Pass Road to Burleigh Street excavated through

joining and grouting of the final CLS watermain pipeline. A 2550mm ID, 3000mm OD, 15 tonne, in-wall joint reinforced concrete jacking pipe (RCJP), supplied by Hynds, was selected for the task and has performed valiantly in consideration of the high jacking and external geological loads it has faced on drives 2 and 3. Construction Construction commenced in October 2018

“We drew on our extensive tunnelling experience to design a predominantly trenchless alternative over 80 per cent of the alignment which re-routed the pipeline route under the busy arterial Manukau Road and the Southern Motorway (SH1).This moved construction away from residential areas and also mitigated the risk of working on roads, the SH1 and the main trunk rail line.” predominantly tuff geology; • The second drive from Clovernook Road to Khyber Pass Road at 1216m set a record for the longest single pipe jack drive in the southern hemisphere by a TBM greater than 2.6m outer diameter. The drive was predominantly through very hard basalt with compressive strengths up to 160 MPa, as well as highly fractured and rubbly basalt zones, requiring rapid adaptation to the regularly changing ground. • The third drive bettered those drive 2 records in November 2020 at 1296 m long from Broadway to Ranfurly Road and passed through the same challenging geology encountered on drive 2. A shorter trenched connection along Edgerley Avenue is under construction to link the pipeline between the Broadway, Clovernook and Edgerley Avenue shafts thereby joining the two separated tunnel sections. Two other trenched sections between Market Road and Ranfurly Road and from the Burleigh Street shaft to the reservoir (making up the 800m (20 per cent) of the pipe alignment) have also been completed. “We performed these works in short 50m sections to reduce impacts on property access along each road and the associated traffic management required,” Richard Atkin, McConnell Dowell’s Project Manager advises. The watermain itself comprises a 1575mm diameter Concrete Lined Steel (CLS) pipeline, typically installed in 12m sections with full penetration butt welded connections. For the trenchless drives, due to geological conditions including rubbly and fractured basalt, clays and alluvials, a Pipe-in-a-Pipe solution was required using a suitably sized casing (sleeve) pipe to provide sufficient access for installation, 48 TRENCHLESS AUSTRALASIA FEBRUARY 2022

following receipt of the resource consents. “We used our 3m OD, 61 tonne Herrenknecht TBM, named Amiria, to complete the three tunnelling sections. Amiria means hard-working in Te Reo Māori, and she certainly lived up to her name,” added Mr Delaney. Manufactured in Germany, the AVN (slurry shield) TBM is well-suited for the excavation and support of the variations in material types along the pipeline route. A mixed ground cutterhead was used for the first shorter drive through the softer tuff, with a full hard rock cutterhead

procured for the two drives through the basalt. A slurry treatment separation plant separates the excavated spoil (rock and soil) from the excavation slurry (bentonite, natural fines and water) so it can be disposed of in an environmentally friendly manner. The separation plant was located at the Khyber Pass Road site for drive 1 and then at the main site office location in Newmarket for drives 2 and 3 from Clovernook and Broadway shafts respectively. The TBM excavates the tunnel with the 3m long 3m OD jacking pipes added at the jacking shaft to extend the casing length between the jacking and reception shafts. Once each tunnel has been constructed, the CLS watermain pipe is installed in 12m lengths into the tunnel, welding adjacent sections together. Each welded joint requires ultra-sonic testing, before the concrete lining is made good across the joint. The annulus between the watermain pipe and inner surface (intrados) of the casing pipe (450mm gap) will be grouted up as each drive is completed to prevent pipeline lift (buoyancy), provide lateral restraint for seismic activity and protect the pipes from corrosion. The first TBM drive commenced in May 2019 and was complete in late June 2019, with peak advances of 18m per shift through the tuff. The CLS pipe was subsequently installed into drive 1 and grouted in place. The TBM was reconfigured for the hard rock drive 2 and began its journey from Clovernook shaft to Khyber Pass Road shaft arriving on

aligning them in confined spaces isn’t easy but the trolley makes positioning each 12m section of steel pipe possible,” said Mr Atkin. “The trolley design had to conform to the internal diameter of the tunnel, be manoeuvrable for both horizontal and vertical curves and be capable of lifting the heavy pipe into its final alignment for welding”. The system also needed to be able to deliver the pipe within a restricted space - between the ‘spacer legs’

“Drive 2 certainly posed a seemingly endless array of new challenges to overcome as the TBM rapidly entered and exited zones of rubbly, blocky, jointed or massive basalt of high strength and medium to high abrasivity. The team needed to adapt quickly to unprecedented conditions, including very high pipe jacking friction loads, significant loads on the crown of the jacking pipes, high cutterhead force against the massive hard rock.”

Amiria - 3025mm outer diameter slurry TBM.

Innovation Innovation has been a key feature of this project, from the original alternative tender proposal of extended tunnelling to logistical solutions developed so the team could move the CLS pipes and equipment over very long distances. The constrained working space within the tunnel makes the CLS pipeline installation operation very challenging. The twelve-metrelong eight tonne pipe sections need to be positioned accurately as there is no access between the product pipe and casing pipe once the product pipe is installed. McConnell Dowell’s in-house design team developed the CLS pipe handling system to be modular and easy to manoeuvre so it could be adapted for different uses. Its main purpose was to transport and align the CLS product pipe sections through the tunnels. “Getting large, heavy pipes into place underground and 50 TRENCHLESS AUSTRALASIA FEBRUARY 2022

installed 90 degrees apart under the free end of the pipe - and align it without access around the outside. The trolley was also modified and used with a scissor lift attachment to lift 80kg grouting pipes and 260kg custom grout valves into position at the tunnel crown. Tunnelling challenges “Drive 2 certainly posed a seemingly endless array of new challenges to overcome as the TBM rapidly entered and exited zones of rubbly, blocky, jointed or massive basalt of high strength and medium to high abrasivity,” advises Justin Shepherd, McConnell Dowell Tunnelling and Underground Group Technical Director. “The team needed to adapt quickly to unprecedented conditions, including very high pipe jacking friction loads, significant loads on the crown of the jacking pipes, high cutterhead force against the massive hard

rock……then this all transitioned rapidly over five to ten metres into a loose rubbly face, and back to a solid face again just as quickly in many areas. We even had encounters with naturally occurring lava caves”. When high jacking frictional forces were identified early, interjack station spacing was quickly revised to bring them as close as 100m apart. This meant 11 stations were required to complete the total drive 2, with each station having a capacity up to 1100 tonnes. In addition, the team worked with international specialists to develop an optimised bentonite mix to decrease the skin friction, support loose ground and efficiently convey the crushed gravel to the slurry treatment plant. The optimal slurry and additional interjacks helped overcome the geological conditions as well as manage the relatively tight horizontal radii of 750m and up-hill tunnelling requirements. The precise steering of the machine, including survey checks every 50-60m, resulted in the TBM arriving within 50mm of target on completion of the second drive. Upon completion of Drive 2, the TBM cone crusher system, STP modules and slurry mucking network were fully refurbished in preparation for Drive 3. The cutterhead was transported to McConnell Dowell’s Fabrication business, fully refurbished and adapted based on the ground behaviour actually encountered on Drive 2. All lessons learnt and continuous improvement initiatives from Drive 2 were implemented from the first excavation cycle on Drive 3. The ground conditions of Drive 3 were essentially the same as those on Drive 2, including further ‘close encounters of the lava cave kind’, but now the Tunnelling Team were armed with a bespoke tool-kit of geological-locality knowledge, experience and additional measures to push on through. As the equipment began to wear down again the final shaft also drew nearer, and the Tunnellers rallied together with their hard working Amiria to complete the final 1296m drive in just over 3 months. “To gain another record for this project after 18 months of tunnelling, across three individual drives, has put the team in good spirits as we near the finish line,” said Mr Atkin. With tunnelling complete, the project team will continue with the installation of the CLS pipe in the tunnel, followed by connections, hydrostatic testing and associated mechanical works. With as little disruption to the community as possible the team continue towards the completion of Auckland’s newest watermain and the vast majority won’t even know the clever engineering underway underground.

Corrie recalls when she finished school that she always wanted to do something in the trenchless field. “I never wanted an office job. After school I got out in the field and a job came about in traffic control on the Gold Coast,” she says. “Once I finished that job, I then moved to Melbourne doing traffic control and that is when I was working alongside a gas client who offered me a job which then led to the job with Adept down the track.” In the four years Corrie has been with Adept

Civil Group she has progressed from learning to operate machines to running the day-to-day operations of the machine. Business development manager Quentin Powell says once he has done a handover on site, the project then becomes Corrie’s. “Maddison is now responsible for running the maintenance of the machines, running crews, and looking after the clients on site,” he says. “This industry has a very heavy male presence, but the way she has had to deal with the different clients and use her own skills and intuition has resulted in the best outcomes for not only the client but the Adept business too. “Her growth and communication with everyone has been a pleasure to watch. And we are only at the start of her journey too.”

As part of the upgrades, an electrical substation on Talmage Street is being built to provide essential power for bigger, more modern trains to run along the line. This will improve the capacity, reliability and frequency of services for passengers.

Corrie says the job was very tricky, with Adept having to work on the railway lines where the trains were and having to overcome challenging and tough ground conditions. “Adept Civil Group was successful in being awarded this project due to our outstanding safety record and previous success with delivery of major rail crossing by micro-tunnelling method,” she says. “Some of the hardest ground conditions that you will ever encounter, have been encountered with basalt rock in excess of 250MPA. Our approach and mindset is: slow and steady will win this race. Our client Metro Trains Melbourne has been incredibly impressed by our whole teams’ approach to this project.” As part of the contract, Corrie says the company also had to modify its drill from 355 diameter to 400 diameter in order to complete the 2 x 36m bores in solid basalt installing a 376mm GRP sleeve. Each sleeve holds 4 x 150mm power conduits. Powell says in order to achieve this, Adept had to adapt the drill itself and make a few modifications to the rods in order for it to centralise in the bore. “It was a fairly involved process. However, going forward this modification will benefit us in the future, opening up a wider range of jobs. Instead of being limited to that smaller diameter, it opens up a whole new prospect,” he says. Describing the project as amazing, Corrie says the next phase will allow the company to adapt the knowledge they learnt from the first part and implement into their future work. As Corrie nears completing another project under her belt, her advice to other women wanting to get into the trenchless industry is “just don’t give up”. “It is hard starting out, but just know you will make it one day,” she says. “It is 2022, so women can do what men do. We might not be able to do certain things at the same capacity but that doesn’t me we can’t do it. Just keep trying and you will make it.” FEBRUARY 2022 TRENCHLESS AUSTRALASIA 53

An innovation award finalist, GeoKrete Geopolymer Aqua Metro is a leading civil construction and remediation company with a vision of enhancing life and livability and places a continual focus on the implementation of innovative technology to provide sustainable construction design and execution.

n alignment with these principles, Aqua Metro identified an opportunity to implement an advanced relining technology, the Quadex Lining System (QLS) featuring GeoKrete Geopolymer, as an innovative, large diameter pipe renewal technology. With the support of Melbourne Water Corporation (MWC), AquaMetro has licensed the technology from Quadex, a Vortex Company – based in Houston Texas, USA, and partnered with Vortex Company’s leadership team to develop the Quadex Lining System’s (QLS) Australian market presence. The pipe relining system offers unrivaled material, equipment, and finish into the Australian market. GeoKrete is a geopolymer mortar liner Innovative Geopolymer lining Technology delivers versatile application methods to avoid costly dig and replace alternatives.

for raw, storm and wastewater infrastructure rehabilitation. For rehabilitation of existing aged assets that have reached, or are nearing end of life, it is an alternative that can provide a far more cost-effective solution than complete replacement. By employing an environmentally friendly trenchless relining technology, Aqua Metro has reduced overall duration on projects, including rehabilitation of existing stormwater pipes, sewer pipes and sewer maintenance hole structures, saved money for the client, avoided disruption to communities and transportation, all the while extending existing infrastructure’s service life an additional 50 years.

Typical Applications QLS is typically specified for large diameter pipes, culverts, tunnels, and other infrastructure suffering from corrosion, infiltration/inflow, and other problems that could lead to catastrophic failure. QLS GeoKrete can be applied to any of the host pipe materials, including: • Corrugated metal • Concrete • Brick • Stone GeoKrete Geopolymer cures through a process of polycondensation and possesses proven, high early and long-term compressive strength. Additionally, with superior bond strength, GeoKrete liners can be applied in layers and under multiple

mobilisations. The chemical composition of GeoKrete Geopolymer makes it inherently resistant to the microbial induced corrosion prevalent in many sewer environments. Geopolymers contain greatly reduced concentrations of calcium hydroxide, commonly found in typical cementitious mortar, furthering the suitability of GeoKrete in low pH environments. QLS is an extremely versatile system engineered to effectively apply GeoKrete onto a variety of shapes, sizes, and surfaces. For angular structures, such as wet wells, junction boxes, box culverts, or other infrastructure with edges, corners, and obstructions, GeoKrete can be spray-applied and trowel finished to achieve restored structural integrity, elimination of infiltration and corrosion protection. The equipment design features advanced technology built into the sled, retrieval system, mixer and pump that allows for a controlled rate of retraction and precision spray application using an application head spinning at high revolution. The GeoKrete Geopolymer has been thirdparty certified as a reduced carbon footprint solution utilizing industrial by-products for much of its ‘active ingredients’. For it to be

considered for Reduced Carbon Footprint (RCF) certification, a carbon footprint assessment compared GeoKrete to the carbon footprint of three baseline products used in trenchless repair systems for structural rehabilitation of pipes. The carbon footprint was then examined from ‘cradle-to-grave’ including the product life cycle stages specified in Table 2 and 3. The results were evaluated using the Global Climate Change Impact method, which conforms to the draft national LCA standard (LEOS-002). The carbon footprint includes the use of Global Warming Potential values evaluated over 20 years (GWP20), factoring in effects from greenhouse gases and Short Lived Climate Pollutants (e.g., black carbon). GeoKrete is a proprietary factory blended, material enhanced with a monocrystalline quartz aggregate. It provides corrosion resistant protection in high hydrogen sulfide environments, increases structural integrity, and stops the infiltration of ground water in deteriorated structures. Unlike cementitious liners, which hydrate to harden, the reaction mechanism in GeoKrete is polymerisation that does not create heat (which contributes to cracking) and yields superior strength and chemical resistance. Once it is applied

onto the damaged surface, GeoKrete quickly forms into a crystalline structure for higher resistance to acids, lower porosity, and greater surface durability. The quick cure rate shortens by-pass time and allows flows to be reestablished much quicker than Portland cement-based mortars. GeoKrete is suitable for rehabilitation of existing large diameter pipelines and structures and has significant advantages where microbiologically induced corrosion is a problem. It is applied by low-pressure spraying or spin-cast application process. Aqua Metro is pleased to be an exhibitor at the upcoming No-Dig Down Under Conference at Sydney Convention Centre in June 2022, and welcome anyone seeking to learn more about Geokrete visit the Aqua Metro at booth 43.

innovative new lining system, offering a range of benefits including fast installation, construction from transparent material and suitability for live loads, such as culverts under road and rail networks. Aussie Trenchless’ Pipe Segment Technology is a segmental pipe rehabilitation system specifically designed for traversable trunk sewers, stormwater

small site footprint,” says Meredith. “The PST grouting process will treat external soil void issues as an inherent part of the rehabilitation process.” Currently, Aussie Trenchless is undertaking a pilot project for a client that will utilise PST for maintenance holes. “The pilot project is south of Sydney as there are some poor condition catchments causing overflow issues at pump stations,” says Meredith.

“The pilot will trial the PST in one manhole and monitor the performance over some time before rolling the maintenance hole refurbishment program out.” Meredith says PST has not been used to rehabilitate a manhole before, as it hasn’t been adapted for maintenance hole lining until now. “What makes this PST unique is that you can access the maintenance hole and complete all work through its existing lid as well as seal all maintenance hole wall faults using a high flow cementitious grout,” he says. “It is also possible to fill external voids in the soil matrix and seal the maintenance hole bench areas as the grout exfiltrates out through the maintenance hole walls.” Meredith says the maintenance hole will be two metres deep, with an inside diameter of 1200 millimetres. Works are expected to be completed by April 2022. PST lining panels are made of polypropylene material, providing a smooth surface with effective

Meredith says PST panels are lightweight, easy to install, and ideal for positioning in tight locations, with the product suitable for all pipe types, including round, ovoid and box culverts. Lining segments reflect the shape of the host pipe and therefore can be both circular and non-circular. Lining of access chambers can also be achieved using PST segments. The ring stiffness of PST can be enhanced or altered by attaching circumferential bars, making the product suitable for installing in deep sewers. The technology does not require advanced installation machinery and has been used to rehabilitate deteriorated stormwater and sewer culverts.

Protecting your most valuable trenchless assets BG Risk Solutions is a bespoke insurance broker specialising in protecting civil construction contractors, including those in the trenchless industry. The company is part of Australasia’s largest general insurance broker network, giving it the leverage to ensure its clients have access to a wide range of insurance companies, products, exclusive policy options and competitive pricing.

anaging Director Ben Gair founded BG Risk after recognising the need for a competent, honest and commercially minded insurance broker which looks beyond the traditional realms of insurance. “We have a proven history for establishing trust with our clients by understanding their businesses, providing sound advice and being their advocates,” says Mr Gair. “Through all stages of the process, we are focused on partnering with clients, achieving great outcomes and offering unrivalled service.” When engaging with its clients, BG Risk takes a three-step approach to providing specific coverage: discover, design and deliver. During the discovery phase the company meets with stakeholders to understand the history of business and identify any issues and/or concerns. These initial discussions also cover prior losses, risk management, compile risk information and determine retention levels. Mr Gair says this planning is vital to providing precise coverage for each client. “We pride ourselves on providing tailored coverage, which makes this exploratory process vital to the delivery of our service,” he says. “A lot of brokers use a cookie cutter approach, or don’t really know the business, which penalises the client because then their proposed insurer doesn’t understand their business.” “During the next stage of our consultation we put together a program to take to market, creating competition among insurers to achieve the best price and the most comprehensive insurance program.” After the coverage has been implemented, BG Risk maintains contact and builds on the contractor/broker relationship, as well as managing any claims that may arise, assisting with risk management and providing advice during the insurance term. While BG Risk’s brokers specialise in 60 TRENCHLESS AUSTRALASIA FEBRUARY 2022

working with businesses across a range of specialist industries, Mr Gair says their expertise lies in construction. “This knowledge and experience means we can identify risks that are specific to your type of business and quickly find the right policy options to match,” he says. “We already work with a number of leading civil construction companies, so we have an acute understanding of the risks that relate to the high value machines trenchless contractors rely-on on a daily basis. “For example, we’ve recently seen an increase in delays to repair and reinstate damaged mobile plant and equipment. This is largely due to manufacture and supply chain issues stemming from COVID.

“Not only is mobile plant a large investment, but is is also vital to productivity and operations on-site, so it’s important we ensure that businesses can continue to operate and have the resources to do so if a loss occurs.” Mr Gair says he’s looking forward to catchingup with clients and engaging further with the industry at his first No-Dig Down Under. “You can learn so much at trade events and nothing beats meeting people face to face. Like anything, insurance is always evolving, so if you own high-value trenchless equipment I would encourage you should stop by our booth and learn a bit more about what we do – you never know we might be more competitive than you think.” For more information visit www.bgrisk.net

Transforming waste into opportunity CDE area sales manager James Murphy talks to Trenchless Australasia about two dewatering systems that are changing the industry.

The HYDRO:TIP is an improvement on that design allowing the vac truck to tip directly into the machine, thus removing the requirement for doublehandling by the excavator.”

The HYDRO:TIP is a dedicated reception station for tipped solid and liquid waste.

DE is the world’s number one wet processing equipment company for sand and aggregates. A key figure in the waste repurposing and natural processing sectors, the company’s mission is to help customers maximise natural resources while promoting greater efficiency and minimising waste. Sand is the third most used natural resource after air and water. As sand is both a depleting resource and one of the most sought-after commodities, CDE believes that recovering and recycling sand and aggregates from construction, demolition and excavation (CD&E) waste is part of the solution to this finite supply. C,D&E waste is typically destined for landfill or is used in low-grade applications, but CDE is supporting material receivers and processors to realise the value of their material. A global original equipment manufacturer (OEM) with a regional base in Ormeau south of Brisbane, CDE delivers turnkey solutions to contractors, end-users and truck operators. James Murphy is the area sales manager at CDE Australasia with more than ten years’ commercial experience in the quarrying and recycling industries within Australia and New Zealand. He talks to Trenchless Australia to introduce two innovative solutions, CDE’s G:MAX and HYDRO:TIP for solid/ liquid waste streams that are transforming waste into opportunity.

“The number of vac trucks in the marketplace is growing, and they’re being utilised across a broader range of applications,” says Murphy. This, in turn, has driven the need for more sophisticated dewatering and waste management systems. “Both the HYDRO:TIP and the G:MAX are designed specifically to handle wet waste from vac trucks and street sweepers, with material also coming from hydro-excavation,

The G:MAX is a dual-stage wet recycling system for solid/liquid waste streams that require classification or dewatering.

G:MAX The G:MAX is a dual-stage wet recycling system for either solid or liquid waste streams that require classification or dewatering. This system can be tailored to the requirements of the waste treatment processes for different applications. “A few years ago, civil contractors and their operators would be tasked with excavating trenches and such using digger buckets with ground engaging tools (GET), straight into the ground alongside electric and

“The development of our G:MAX and HYDRO:TIP solutions demonstrates our constant striving for innovation and a commitment to finding workable solutions for the challenges facing material processors today. Our technologies are having a transformational impact and the industry is taking notice, as evidenced by the fact that last year CDE made more bookings than ever before.” telecommunication cables, sewerage and other infrastructure. Even with ‘dial-before-youdig’, they were running the risk of causing damage,” says Murphy. “Due to demand from both industry bodies and contractors for safer work practices and from the local government or vendor in protecting their in-ground assets, there has been an obvious shift towards non-destructive digging. With a vac truck you’re using a vacuum to suck up the dirt, not penetrating the earth or running the risk of impacting some of those infrastructure services.” As the regulations in the industry have become more stringent, contractors have needed to find a more sustainable approach with what they do with the material. Sawdust is widely used as an alternative to these new CDE technologies. The dry sawdust absorbs moisture from the incoming material to reduce the overall moisture content to a level accepted at landfills. However, this increases the bulk volume of material, resulting in higher disposal costs for contractors. Processing hydro-excavation material, the G:MAX dewaters the material and eliminates the need for sawdust. Maximum dewatering of the grit fraction ensures ease of product handling and reduces both disposal costs and environmental footprint. “Once separated, the excess water is processed through a water management system - CDE also supplies equipment in that space,” says Murphy. “By separating the solids using the G:MAX or the HYDRO:TIP, the additional water can be processed through the CDE AquaCycle thickener. Any sub-75micron particles from the process water are thickened to a concentrated sludge and can be even further mechanically dewatered to a spadeable state with a centrifuge. Depending on the local authority, the remaining clarified water can, in some instances, be trade discharged.”

minimal downtime for truck operators. The HYDRO:TIP effectively dewaters and grades hydro-excavation waste. The patented technology provides maximum dewatering and separation of slurried waste materials to generate clean reusable sand, aggregates and water products. Material that enters the system is screened, rinsed and separated. The recovered large solids can be stockpiled directly or refined further to produce additional fractions of saleable aggregate. The fine fraction can be dewatered from a slurry into saleable sand. “The recovered materials can be sold as bedding or drainage sand, recycled stone and drainage aggregate, saving the operator on disposal fees. However, even diverting it from landfill will increase the profitability of your

operations,” Murphy explains. Increasing the volume of recovered material is not only economically sensible, but it also minimises waste destined for landfill. G:MAX and HYDRO:TIP provide an efficient and safe dedicated system for processing vacuum tanker muds and other liquid wastes. Such is the positive economic and environmental impact of CDE technology that the firm recorded its most successful year to date in 2021. “The development of our G:MAX and HYDRO:TIP solutions demonstrates our constant striving for innovation and a commitment to finding workable solutions for the challenges facing material processors today. “Our technologies are having a transformational impact and the industry is taking notice, as evidenced by the fact that last year CDE made more bookings than ever before.” CDE will be promoting both the G:MAX and HYDRO:TIP systems at the 2022 No-Dig convention and exhibition Stand 79A.

After a pilot bore is made from the entry to the exit, a HDD string is then guided along the drill path. Unfortunately, damage to steel pipelines during the HDD installation is commonplace; often rocks and debris will remain in the pilot bore, subjecting a pipe to abrasion and gouging. “When a coated steel pipe length is pulled through with a corrosion protection on the outside, the coating is subjected to rock and debris that can create heavy impact, gouge, shearing and abrasion forces to the parent coating,” Denso’s national product development manager for pipelines George Wettenhall explains. “Abrasion resistant outer wraps (AROs), or BoreWrap specifically, reduce the risk of coating defects and gouging and abrasion. Bore-Wrap is made up of a patented fibre architecture to protect against a variety of potential pipeline threats caused by the stresses of HDD installations.” Denso’s Bore-Wrap is a field-applied abrasion resistance outer-wrap suitable for joint coatings, mainland coatings and shrink sleeves in trenchless installation and Wrapping should occur circumferentially to begin, ensuring the leading edge has a minimum of two layers.

pipeline coating and cured with water. “Each roll is supplied in a foil carrier bag that keeps the Bore-Wrap intact. The roll itself is impregnated with urethanes,

so once it is open to air and moisture, it starts curing,” says Wettenhall. “We wrap that roll around the pipe prior to application, so it will fit a range of pipe sizes. The BoreWrap is moisture-cured, unlike other AROs that use UV curing. UV Liners often require cutting, special lighting and shielding from UV. Bore-Wrap can be applied in-situ with the addition of only water.” Firstly, an operator must prepare the surface by removing any loose scale or foreign matter. Then, they will wet the surface of the pipe where the roll is to be applied. As BoreWrap is water activated, it is necessary that the water is continuously sprayed onto the surface and underbelly of the roll as it is being applied. Wrapping should occur circumferentially to begin, ensuring the leading edge has a minimum of two layers. Once the wrap is completely saturated, immediately begin wrapping the compression film over the wrap with tension applied. Once fully compressed, use the perforating

tool to puncture the film, allowing excess moisture, resin and CO2 from the curing process to escape. The operator should allow for the roll to remain under compression while it cures before removing the film. The finish will appear seamless and fully fused together, creating an impenetrable outer barrier. Case study In a recent case study, an ageing pipeline crossing beneath a creek required replacement due to corrosion. The pipe was installed using HDD 50 ft deeper than the original line. During the pilot drill, the ground was found to contain cobble and rock fragments that could pose a threat to pipeline integrity. The contractor opted to install a Denso BoreWrap over the welds to protect them from damage during the pull-in. The remainder of the pipe had only an FBE coating. Once the pipe was pulled through the bore hole, it was apparent that the mainline of the pipe suffered significant damage to the coating, causing the bare steel to become exposed. By contrast, the welds that were protected by the Bore-Wrap did not endure any damage. As is characteristic of trenchless

applications, the Denso Bore-Wrap minimises the need for costly spot repairs or re-pulling pipe due to damage. BoreWrap is a simple, effective and economical solution for guaranteeing asset integrity in abrasive conditions. Contractors

have commended this Denso product for its flexibility, ease of application and exceptional protective performance. Denso will be exhibiting the Bore-Wrap at this year’s No-Dig Down Under convention and exhibition.

Reducing the social costs of pipeline installations with microtunnelling

VISIT US AT BOOTH

60 NO-DIG DOWN UNDER 2022

The installation of underground utilities has the potential to cause major disruption to the community and surrounding environment depending on the method used. Microtunnelling offers an alternative solution to open cut methods for installing pipelines quickly and accurately while lowering the overall social costs.

raditional open cut methods of pipeline installation require the length of the pipeline – which may include roads and footpaths – to be blocked off for a period of time to allow excavation, installation and restoration works to take place. According to Stuart Harrison, Managing Director of Edge Underground, using a trenchless method such as microtunnelling instead of open cut methods has a number of benefits that limit the disruption caused by the construction work. “Microtunnelling is a pit-launched technique with only an entry and exit pit required to be excavated for the installation,” says Harrison. “This allows installation through one small incision between the entry and exit pits, rather than having to tear the whole street open to do it.”

Limiting disruption to the community The AXIS guided boring system is a modular microtunnelling machine that can be set up in a way that reduces the amount of space needed for the construction site, therefore reducing the amount of pedestrian pathways taken up and the need for road lane closures. Additionally, this reduces the loss of parking spaces, which can lead to decreased parking meter revenue for the city and lower revenues from parking fines. Another social cost of pipeline installations is the loss of trade. Construction zones can decrease accessibility to businesses due to congested traffic conditions, blocked parking spaces and barriers from the construction site itself. Businesses can lose customers, who prefer to go to more convenient places, and those depending on deliveries may have problems Microtunnelling requires minimal excavation.

The AXIS is modular, allowing it to be set up in a way that reduces the amount of space needed for the construction site.

with their supplies. Microtunnelling requires less excavation and less restoration afterwards, so project times are shortened, minimising the disruption to trade. “While open-cut methods leave lengthy stretches of open trenches that need to be restored after construction, microtunnelling leaves minimal surface scarring and requires significantly less restoration of the landscape,” Harrison says. Depending on the project requirements, destruction of road surfaces may be able to be designed out of the project altogether. “Unlike traditional methods, the AXIS system extracts the ground being tunnelled through rather than displacing it. It is designed to cut and extract the ground as it proceeds, and in doing so has little to no influence on the ground directly surrounding the installation,” says Harrison.

The AXIS helps reduce community disruption during construction.

With microtunnelling, destruction of road surfaces may be able to be designed out of the project.

The AXIS system also uses a vacuum extraction method that provides continued support to the ground by using a pipe jack system approach. This ensures quantities of both incoming and outgoing materials are reduced, causing less disturbance to the environment and minimising the size of the work site. A healthier and safer work site Open excavations result in a significant amount of dust in their surroundings. Cleaning needs, and thus costs, increase while the quality of life for people living near the construction zone decreases. As excavation requirements are

drastically minimised with microtunnelling, there is also less dust produced by the site. Noise pollution is also a major by-product of construction sites. The use of heavy construction equipment results in higher noise levels in the vicinity of the work area. As projects that employ efficient microtunnelling systems can be completed faster, the noise pollution cost is lowered and the impact on residents is reduced. Worker safety can also be improved by employing trenchless technologies such as microtunnelling. The large amount of excavation required for open cut methods of

pipeline installation creates a greater safety risk to workers and increases the chance of public interference, especially in urban areas. Microtunnelling requires minimal excavation so there is less chance of safety problems arising from trenches. The AXIS guided boring system is the only microtunnelling machine on the market that has been designed with unique safety features to offer a superior level of operator safety and reduce the risk of materials falling into the pit and hurting workers.

10 NO-DIG DOWN UNDER 2022

To get something done, you have to tread new paths. This has always applied to IMPREG since the company’s birth in 1999.

ountry Manager Kevin Woolf tells Trenchless Australasia that IMPREG recognised early on that trenchless pipe rehabilitation using cured-in-place pipe (CIPP) liners is the technology of the future. Further developing this avenue, the company’s CIPP liner systems are developed using innovative high-tech processes, and set new standards. “Our success proves us right. IMPREG CIPP liner systems for UV curing are used all over the world,” he says. “We are a reliable solution partner at all times, and commit ourselves to the highest future-proofed quality and to environmentally conscious conduct.” Woolf says the IMPREG liner GL16 was developed in 2016 for all common pipes from DN 150 up to DN 2000. As a result of good material characteristics and new fibreglass design, IMPREG was able to develop a more finely nuanced gradations of wall thickness. Not only does this benefit the company’s customers financially, but the IMPREG liner GL16 makes it easier to deal with large dimensions.

“Our success proves us right. IMPREG CIPP liner systems for UV curing are used all over the world,” he says. “We are a reliable solution partner at all times, and commit ourselves to the highest future-proofed quality and to environmentally conscious conduct.” “Through the IMPREG liner GL16, the company has consistently extended its position as a technology leader in the market segment from DN 1200 upwards,” Woolf says. “The unique construction of the IMPREG liner allows a certain level of compensation for dimensional variations in the pipe. We can produce defined dimensional changes in our factory. “In the Australian Pacific region our range js GL16 which is made up of 0.8 mm fibre glass layers and inner foil, outer fleece and a yellow UV protection sleeve from DN150 to DN2000 with wall thickness ranging from 3 mm to14.6 mm.” Woolf highlights that the high-tech CIPP liners from IMPREG are simply inserted into the pipes via the manholes, and cured using UV light. The rehabilitated pipe can then be returned to operation immediately after

With a warehouse located in Brisbane, standard liners in Australia and New Zealand are available to be shipped across the nation, with the liners ready to go for: DN150, DN225, DN300, DN375, DN450, DN525, and DN600. Woolf says the main aim for IMPREG this year is to continue supporting its customer both onsite and technically. “Our biggest goal for 2022 is to continue our after market care,” he says. “The customers’ success is our success, meaning our after care is just as important as our product quality.” As part of the company’s after market care in Australia, Woolf is able to help with structural designs, review CCTV on job sites and provide onsite technical support. “New customers will also have the opportunity to attend a training session and find out how we already implement the trenchless pipe rehabilitation of the future,” he says. “Our application engineers are onsite for your first project, and support you with advice and assistance during the installation of the IMPREG liner.” With no need to bring a project to a stop, IMPREG is also able to rapidly and effectively rehabilitate pipes which carry aggressive or higher-temperature waste waters. “IMPREG CIPP liners are future-oriented, high-tech products which provide all options for the rapid, effective, and economical rehabilitation of pipes of very differing diameters,”says Woolf. “With our liners, we at IMPREG set new standards that will lead us into the future.”

The GeoKrete liner has a minimum 28-day compressive strength of 50MPa and the required thickness can be varied based on design requirements. The lining process can be installed via accessing existing manholes without any demolition needed. GeoKrete technology is suitable for pipes and structures above 900mm in diameter and is not restricted by the structures shape. It can be applied to various existing host structure materials such as concrete, brick or steel. Geokrete has a very short curing period, meaning rainfall events have minimum impact to the project progress with all equipment easily removed and repositioned as required. Aqua Metro Services has had great success when employing this technology to projects in Victoria.

Reducing inflow and infiltration ISC Services is dedicated to helping water and wastewater authorities improve safety, protect their sewerage, potable and stormwater networks cost effectively to maximise the operational life and return on investment of their assets.

n January 2002 Dennis Bentink created ISC Services and has since worked closely with a wide range of councils and water authorities across Australia. Providing inflow and infiltration (I/I) assessment, conducting inspections at hundreds of maintenance holes, pump stations and sewage treatment plant inlet structures, Dennis has helped customers minimise asset degradation and reduce operational and whole of life asset costs. Dennis tells Trenchless Australasia that when he started the business in 2002 it was a mobile laboratory and consulting firm with the focus on odour and corrosion testing of sewerage networks and treatment plants. “Rather than taking a sample back to a lab for testing, I brought the lab to the maintenance holes in the street, pump stations & treatment plants, doing discrete samples and continuous monitoring there for odour and corrosion using both liquid and gas phase testing,” he says. “Customers were then provided our independent report with two or three options to address the odour & corrosion issue and they could go directly to the market to source the appropriate solution. “While carrying out the testing at MH’s and pump stations, we would often provide additional support by notifying our customers of other operational issues observed such as inflow/ infiltration, damaged or poorly constructed MH’s and buried lids.” This lead to requests for support to solve these additional operational issues and, following on from some detailed research into options, the customers were happy to purchase the solutions from ISC Services. This helped shape the business to what it is today – selling solution-based products. In 2016 ISC Services commenced offering a range of specialised products and systems to allow customers to reduce I/I as well as improving safety and efficiency for personnel involved in repairing and raising maintenance holes, pump stations, pits and pipes. Dennis says that the systems offered are high-quality, well established and proven in the

US and Canada from leading manufacturers including Sealing Systems Inc., Cretex Specialty Products and HydraTech, with independent testing and long-term case studies available. “With our proven range of simple-to-use infiltration control solutions, ISC Services has already helped many customers to prevent the development of infiltration problems in new precast concrete structures as well as to repair existing assets and reduce I/I, helping to take pressure off maintenance crews and sewerage assets with cost effective solutions,” he says. Many of our customers want innovative and sustainable solutions which will improve safety and reduce the operational and maintenance pressures on their assets. They realise that here is no sense in doing things the same way, hence ISC Services’ approach of “Solving old problems in New, more efficient ways”. “These solutions provide an excellent return on investment, allowing customers to regain capacity and control of their networks during rain events, reduce overflows and delay unnecessary capital works that are often

76 NO-DIG DOWN UNDER 2022 planned to help cope with unwanted water.” As part of the business’ move from consulting to product supply, Dennis says a key to the drive for the selection of products was looking at what problems customers were having and finding innovative solutions that could provide a quick and cost effective, permanent fix for the customer. One of the most notable innovations that is proving very popular, is the Pro-Ring grade adjustment ring that allows councils and contractors to safely and cost effectively raise low and buried covers & frames, stopping I/I and improving access. Pro-Ring weighs 1/20th that of concrete yet passes load testing to Class D trafficable (AS3996:2019) making it much safer and easier to handle and install and needing much less equipment to transport and move than concrete. In addition, they create a water tight & gas tight seal and will not corrode due to hydrogen sulphide gas. “Contractors regularly comment that they are impressed with how light weight and safe Pro-Ring is, making

it easier for them to complete jobs quickly”. To further enhance its range of offerings, ISC Services has teamed up with Metz, a Melbourne-based company that specialise in manufacturing protective coatings and tiles for very aggressive environments. “While the Metz coatings have a wellestablished record in industrial environments, we are in the process of getting one of its products tested and approved to be used for Sydney Water, which is expected to be completed by April,” Dennis says. “Considering the aggressive environments Metz products are already used in, we are confident that they will perform well. A demonstration on a maintenance hole already suffering significant corrosion was done in 2016 with the Metz 33EN and this has proved to provide excellent continued protection”. Building on the company’s experience and success, it was recently awarded to be on the panel of providers for Tweed Shire Council for Protective Coatings for Water and Wastewater. “Tweed Shire Council have been proactive in working to reduce I/I & have been utilising our innovative solutions including Pro-Ring & Flex Seal Utility Sealant. This is yet another great opportunity to continue to support their operations and maintenance programs with the quality Metz coatings.”

Preventing Infiltration with Gator Wrap external joint seal.

Specialising in inflow and infiltration, Dennis understands every sewerage network is different, but knows sewer manholes generate a disproportionate amount of I/I. He says the key is assessing and identifying major contributors as an important tool to help water authorities effectively take action to mitigate problems. While there are a number of causes of I/I, ISC Services sees failed joints in both new and old assets as well as low and buried maintenance holes as the most common causes. “This can be in maintenance holes

(particularly the chimney or neck where there are often multiple joints close together and near the surface) as well as pump stations, pits and pipes,” Dennis says. “The simplest approach is to look at how sewage flow changes during and immediately after rain events. If sewage flow increases (either at the treatment plant or at pump stations) then rainwater and/or ground water is entering the network. “There are options for councils and water authorities to get specialist contractors to do preliminary investigations through to detailed studies. By working with ISC Services, as we are experienced in I/I, it will allow customers to determine what their I/I assessment and management goals are, which we can then tailor a staged plan and program to suit your specific circumstances and budget.” With a commitment to continue to identify new and innovative technologies to solve problems, Dennis is continues to expand his market and product range where customers can come to “ISC Services as a toolbox of solutions and products, Solving old problems in New, more efficient ways.”

Building for the future Over the last decade, KOR has grown its national footprint to support contractors across Australia and New Zealand.

By the end of March this year KOR will have three mobile service vans in operation in Victoria and New South Wales.

he cornerstone of the KOR vision is to make it easier for its customers, which has led to the establishment of a new major facility in Dandenong, Victoria. Chief Executive Officer David Gurrie tells The Australian Pipeliner that over the past 18 months he has been with KOR, he has been focused on identifying opportunities to improve operations and customer outcomes. “Dandenong was a facility we identified to become the cornerstone for pre-delivery, warehousing, assembly, service and engineering operations. It needed to be self-sufficient, staffed with trained KOR staff personnel and fitted with suitable equipment” he says. “We analysed our Victorian operations across multiple sites using techniques such as SWOTs, time and motion studies, expenditure analysis, and general capability and capacity reviews. We came to a quick realisation that we can build a more efficient and capable operation by insourcing and centralisation. This will be able to provide a better quality of service and deliver customer outcomes in a more controlled way. That lead down the path of doing our own major site.” Gurrie says KOR wanted to centralise 80 TRENCHLESS AUSTRALASIA FEBRUARY 2022

operations, employ more trades for servicing, and setup heavy workshops to better support their customers and enable further partnerships. This led to the development of the Dandenong Engineering and Operations facility. The facility is on a 8000 square metre site with a 4000 square meter building serviced by 8T cranes. The site will support a large national warehouse, 10 service and assembly bays, and a fabrication area. The site will also allow KOR to strenghten its partnership with Schwarze Industries. In July 2021, KOR secured an exclusive distribution in Australia and New Zealand for Schwarze Industries, highly acclaimed for its durable sweeper products, and renowned for its innovative design and quality. Gurrie says by opening the Dandenong facility the company can better support the Schwarze agreement which requires domestic sweeper body installation onto locally procured chassis, supported by engineering and fabrication operations. “That is how I came into the picture, to rapidly improve our operations and enable this quick expansion to identify and procure a suitable site. At the same time, we also

began developing internal trades capability to perform servicing and introduced mobile servicing. The challenge has been hiring trades during COVID-19.” “Our mobile service began in early 2021, with additional mobile service vans under commission. By the end of March 2022, which is the same time as the commissioning of the Engineering and Operations facility, KOR will have three mobile service vans in operation, with one van operating in NSW. We have plans for further expansion of mobile services and workshops over the next 12-18 months.” Gurrie says the goal is to improve customer service using KOR workshops and service vans by providing everything a customer needs, at their doorstep, across Australia, to carry out a service. “The service vans give us a capability that we weren’t able to provide before. We will be able to send the vans out to customers and perform services and repairs onsite. The vans are equipped with over 200 parts bins and all the right tools and equipment,” he says. In addition to the mobile service, the Engineering and Operations facility supports major services and repairs.

46 NO-DIG DOWN UNDER 2022 “This means when we have a major repair, we can do it safely and efficiently with the overhead cranes, supported by trades and engineers, to complete the repair quickly, getting the equipment back on the road as fast as possible.” Gurrie says. Gurrie, with a background in engineering, says KOR has been able to expand KOR’s expertise and employee more engineers. “Engineering capability is important for assembly operations, to custom design and solve problems for customers, to enable KOR to provide better feedback to Cappellotto and Schwarze based on our customer feedback to improve products, to generate training material, and to continue improving our aftersales service outcomes” he says. Gurrie says parts warehousing is another

major element for successful aftersales support as customers demand a rapid turnaround for the supply of parts. “We are also going to expand our national warehouse, which will triple in size as we are currently over capacity, and further streamline our operations process. We are now supporting both Cappellotto and Schwarze with parts and have a mandate to stock parts in Australia where practical to reduce backorders. This national warehouse also supports our satellite warehouses located

across Australia and New Zealand.” KOR is investing in the future in pursuit of ensuring the ongoing best support for our customers. “It is in the DNA of the KOR team to be there for our customers no matter when they call upon us,” says Gurrie. “We have developed our people and systems to support our customer service charter driving excellent outcomes that the team at KOR pride themselves on and we are only getting started.”

Zipping past the competition Kwik-ZIP is a privately-owned and operated business originally started by the owners of BDC Drilling in Western Australia. Before the conception of kwik-ZIP, the founders had a vision to develop a concept for a non-corrosive plastic bow spring centraliser they could use within their drilling business.

Kwik-ZIP’s HDX-90 spacer model was utilised for the Rail Infrastructure Alliance project in Sunbury.

Kwik-ZIP’s large range of spacers caters for a wide range of carrier and casing pipe size combinations.

82 TRENCHLESS AUSTRALASIA FEBRUARY 2022

stablished in 2001, kwik-ZIP has since engaged in the design and manufacture of non-metallic centralisers and spacer systems for a wide range of industries including the trenchless, pipeline, resources, and civil construction industries. Kwik-ZIP now markets its products both domestically and internationally, owning the patents and intellectual property to all of its designs. Kwik-ZIP’s centraliser and spacer systems have been developed to solve supporting, grading and centralisation challenges in the trenchless, HDD, pipeline, vertical production drilling and ground engineering industries. Casing spacers are used extensively in trenchless pipeline installations to facilitate the slip-lining of a range of water and sewerage pipelines, preventing damage to both the carrier pipe and the casing during installation. Manufactured from kwik-ZIP’s engineered thermoplastic blend, The kwik-ZIP HDX & HDXT Series is a non-corroding, non-metallic casing spacer for Pipe-in-Pipe (PIP) applications such as slip-lining and cased crossings for all medium-to-heavy-weight pipe materials including: steel, DICL, MSCL, GRE, PVC and HDPE, and other pipe material and are a completely non-metallic solution. On a recent Rail Infrastructure Alliance project in Sunbury, horizontal and directional drilling specialist contractor Jelmac Directional Drilling utilised kwik-ZIP HDX-90 spacers to facilitate the slip-lining of a 355mm HDPE carrier pipe over a 66-metre run. Kwik-Zip spacers were specified at 1.5 metre intervals for this project as per Melbourne Water

Flick the paper – make the transition today Kynection offers a suite of technology applications which can help companies that operate in the trenchless industry work more efficiently, while ensuring that safety comes first.

ynection, originally called Fleet Effect, was born in 2006 with a focus on creating technology that would help heavy vehicle operators manage operations and reduce their impact on the environment. Champion of Growth & Communications Jonathan Patchell says in 2008, during the early phase of the business, the management team had become entrenched within the local heavy vehicle industry and identified a real need in the marketplace for systems that would help transport operators manage heavy vehicle compliance (NHVAS and CoR), as it was increasing in complexity and becoming too much for many companies to manage. “Based on the skillset of the management team (Courtney Smith, Kasie Smith and John Tsoucalas), this change-in-direction was perfect

as they’d all come from consulting backgrounds with focuses on operational process and compliance,” he says. By 2009 the company had proved itself to be a real player in the market by completing Australia’s first pilot for Electronic Work Diaries (EWD) with a Queensland-based quarry fleet. Fast forward to 2018, Fleet Effect undertook its first merger by merging 44 per cent of Vertical Matters into the business. As part of this deal, it tripled its employee headcount and diversified its software portfolio by offering Quality Management Systems allowing customers to receive Triple ISO Certification through Quality (ISO9001), Safety (AS/NZ4801) and Environment (ISO14001). As part of this merger, clients such as KONE Elevators, Mitchcon, Rangedale,

37 NO-DIG DOWN UNDER 2022 Underground Cable Systems, VSA Group, Roadsafe and Johns Lyng Group joined the Fleet Effect family. With the part acquisition of Vertical Matters and diversification of the business into new areas, Fleet Effect officially rebranded to Kynection in May 2019 - with Knowledge in Motion as the underlying tagline from parent company Autolync. Today, Kynection offers One System for all, which encompasses the whole workflow of a business in one spot. Jonathan Patchell says the company identified a gap in the market for a company to be integrated into existing accounting systems and other third-party applications thus creating the “One System”. “Kynection can be slotted into any business, and we can be integrated into any accounting system and make that seamless transition from a clunky paper-orientated business workflows to a paperless streamlined business,” he says. “By having an organisation managing these different aspects of the business, the customer is able to contact us, and we can fix it. Essentially it removes the middleman and streamlines a lot of customers’ billing systems and operations.” Kynection has a unique way of doing integrations. Jonathan says through its up-todate expertise in technology, the company is able to integrate a lot of its hardware customers’ purchases from OEM manufacturers and from third-party software systems, making it an easy transition into a one-system approach. Not only does it optimise teamwork by converting “paper to glass”, but Kynection allows clients to have real-time communication, remotely manage employees, suppliers, and subbies, win more tenders, bids and contracts, and have end-to-end supply chain fulfillment. In the trenchless industry Kynection is able to offer full vehicle compliance by putting AI cameras in trucks, which links back to its job management system in real-time on the “One System”. Jonathan says through this the company is able to manage driver awareness with the

camera system which then feeds back to the operations system. “We manage the operation system with the scheduling of the trucks and crews, which overlap that with the competency crew,

detailing what they are competent of doing and whether they have been inducted. It also identifies what assets have been introduced to those projects as well,” he says. “This means clients get all the information

they need in one place and allows for a smoother operation and management of their business overall.” As part of Kynection’s cloud-based platform, clients have access to the following: project management, job management, time and attendance, asset management, equipment management, eForms, task management, contractor management, quoting/invoicing, document management, tender management, contracts, human resources, and CRM. Jonathan says his team of consultants are experienced with over a collective 100 years of experience at providing a full turn-key system that includes its cloud-based technology suite, as well as any required hardware teams may need. Kynection is a unique business that supplies the complete full systems of hardware and software including any support. This is a real game changer for the trenchless industry as they just need to have one point of contact for their operational systems. “Ultimately our goal is to make it easier to view data and business information in one place,” he says. “Our technology will let you improve operational efficiency of your facilities maintenance businesses and ensure that use of paper is minimised.”

Infrastructure sector growth and value Maxibor’s national business development manager David Turner provides insights into how horizontal directional drilling (HDD) design and delivery providers can help achieve growth and add value to the infrastructure sector through the next five years and beyond.

he Australian infrastructure sector is going through a significant growth and change phase as the world emerges post-Covid and refocuses on economic and environmental development. The HDD sector is well positioned to play a significant role in designing and delivering infrastructure projects that can be part of the economic recovery and provide climate change mitigation solutions. David Turner has spent several decades working in the trenchless industry. In his business development and HDD operational roles at Maxibor, Turner is very familiar with most of the major infrastructure projects requiring HDD that have been completed in recent years; those currently in progress; and those that will be designed and delivered across Australia over the next five years. Turner predicts exciting times ahead for the HDD sector from a growth and value perspective. He says, “Companies like Maxibor, which have a widely-recognised reputation for

the successful design and delivery of all sized HDD projects, have a wealth of knowledge that can be used at all project phases to add value and help optimise outcomes for all stakeholders.” Over the next five years, governments and private sector infrastructure asset owners are set to make unprecedented investment in infrastructure projects. Free from Covid constraints and backed by economic support from Federal and state governments, it is important that the projects are designed and delivered in a manner that takes full advantage of the installation benefits that HDD can provide. At a project’s concept level, it is important that HDD expertise is part of the early discussions, as HDD involvement at this stage will bring greater understanding of the process and its benefits, plus innovative opportunities for the installation of the infrastructure. “Providers like Maxibor are already delivering larger diameter and long bores in excess of 2 km,” says Turner. “It is exciting that early

Once a project moves to the expression of interest (EOI) stage where bidders need to progress design and construction methodology to a more detailed level, having the HDD design and delivery experience in the bid team can be pivotal to the success of the bid. One recent example is the Sydney Water Refresh Vaucluse to Diamond Bay project. Comdain worked closely with Maxibor and WSP to present Comdain’s winning bid for the design and delivery of this project, which included a 1.85 km pipeline. The cooperative approach of the bid team and the collaborative NEC4 procurement approach by Sydney Water is creating a project delivery framework which will optimise outcomes for all Maxibor’s Gallagher 660e maxi-rig, informally known as The Hulk, is the only electric maxi-rig in the HDD industry in Australia.

stakeholders on this showpiece major project. Maxibor now has one of the largest HDD maxi-rig fleets in Australia. This includes a Vermeer 330x500, American Auger 660, Gallagher 600 and a Gallagher 660e (The Hulk). Maxibor also has the four most powerful pumps in the HDD industry, with its two Gardner Denver PZ8s and two Gardner Denver PZ9s. The grunt of the rigs and pumps means that Maxibor can take on any length bore. “Project decisionmakers understanding the capabilities of the available HDD equipment is so important across the full project cycle – from concept, design and delivery – as this helps to optimise the value of a project,” says Turner. Maxibor’s Gallagher 660e maxi-rig, informally known as The Hulk, is the only electric maxi-rig in the HDD industry in Australia. The electrified spread comes with its own substation and can drill up to 3.5 km in a single shot with a diameter up to 1.6 m. According to Stephen Loneragan, one of Australia’s leading HDD design engineers, “Electric spreads provide new design and delivery solutions in Australia, especially for complex capital city water and sewer or power and gas projects where setup, noise, emissions, congestion services and ground conditions all

present challenges that need to be overcome.” There is a growing need for government and private sector funders of investment in infrastructure to meet Environment, Sustainability and Governance (ESG) requirements. Both ESG and climate are at the top of funders’ lists in terms of risk mitigation, and they want to be able to demonstrate that they are investing in a way that optimises longer term sustainability outcomes for all stakeholders. In this context, trenchless technology, and more specifically HDD, can provide solutions that are compatible with critical

needs of funders, asset owners and the broader community. Installing infrastructure “down under” is an effective solution for Australia as the country faces the impact of climate change. Having telecommunications and electrical assets underground provides many obvious safety and environmental benefits – one need only look at the ravages of the more extreme weather conditions like the 2019-20 bushfires to see that having infrastructure securely installed at depth provides a significantly safe community. It also facilitates the recovery process as services can be more quickly restored. Maxibor’s chief executive Rodney O’Meley says the push for early cooperative involvement in projects and environmentally friendly delivery methods reflects the importance the industry is placing on the long-term picture. “If a project is designed well, its chances of successful delivery and longer-term value are much more likely to be better achieved. Investment in disaster resilient infrastructure needs to be seen not as an additional expense but as an opportunity to create shared value for businesses and society,” says O’Meley.

Tunnelling to the future S&Z Australia is one of Victoria’s leading providers of horizontal directional drilling services and has recently expanded into tunnel boring services. S&Z Australia has purchased a Bohrtec tunnel boring machine which was delivered in January 2022.

&Z offers a variety of trenchless installation methods including horizontal directional drilling (HDD), tunnel boring (TB) and auger boring (AB). General Manager Jim Pound tells Trenchless Australasia that the company is a trusted and valued partner to industry leaders throughout the water, sewer, power, telecommunications, and gas segments, providing trenchless services throughout southern Australia. “Our company has skilled installers using the latest equipment,” he says. “Our aim is to exceed customer expectations and provide solutions for difficult projects where open trench construction is not an option. Through S&Z Australia’s commitment and dedication, Pound says the company has become an industry leader and a trusted specialist subcontractor. Traditionally known as a directional drilling company, S&Z Australia has recently made the move to tunnel boring. Starting with a small drill, the company has grown, purchasing the larger drills and rock drills, working mainly in the water, sewer, gas, power, and telecommunication sectors. However, when S&Z started working in 90 TRENCHLESS AUSTRALASIA FEBRUARY 2022

the sewer industry, Pound says there was an opportunity to move into the tunnel boring market due to directional drills not being as precise as tunnel boring machines in achieving grade. “We like to think we are at the beginning

of our growth cycle. I have only been part of the company for two and a half years and the company owners keep investing back into it,” he says. “Both of the directors are hands on working with the teams out in the field and working on the machines. This gives our crew a really good culture as our directors are out on site and helping ensure all the work is being done safely, accurately and economically.” “We are only a small business with three Horizontal Directional Drills (HDDs) and two Tunnel Boring Machines (TBMs), but we have a large variety of clients and work on a range of different infrastructure projects from rail improvement projects, new water & sewer mains, to being part of Snowy 2 the “largest energy project in Australia” that will underpin Australia’s transition to a renewable energy future. “We really want to focus on being trenchless specialists in both directional drilling and tunnel boring.” With the move to tunnel boring comes a new drill, which was purchased from Bohrtec and delivered in January 2022. When selecting the machine Pound says the company not only looked at the quality of equipment but the versatility and the suitability in all different ground conditions. “The tunnel boring market is always growing because there is more call for trenchless technology and directional drills have their

33 NO-DIG DOWN UNDER 2022 limit,” he says. “We feel there is an opportunity in the market as there is a growing demand for tunnel boring machines.” As a result of the tunnel boring machine, S&Z Australia hope its work will expand across Australia as the new machine will allow it to drill up to 800 mm diameter of sewer and storm water pipe, or other pipes and conduits where setback for a HDD machine is not achievable. Pound says when installing pipe on a flat grade a tunnel boring machine with a laser is needed to help keep it on grade and on the correct alignment. “There aren’t many Bohrtec machines in Australia and we believe it will be an excellent option for any ground conditions we will

encounter here in Victoria or anywhere in Australia,” he says. With a commitment to minimising the impact of its activities on the surrounding environment through adherence to its Environmental Management System, S&Z’s philosophy toward environmental management is one of education, communication, continual improvement, and whole company involvement. By embracing these principles, the company aims to minimise pollution created during any works process and continually monitor its impact on the environment through ongoing

reports, audits, and inspections. “S&Z endeavour to constantly improve our installation methods and efficiencies. We pride ourselves on innovation that provides benefits to the client and the environment,” says Pound. “The rise of trenchless technology has significantly grown in recent years, and we really want to be the experts in it and offer numerous installation methods to provide quality solutions to our clients, their customers and the community.” For more information visit www.sandz.com.au

Save lives, protect your reputation and prevent your next asset strike Inaccurate records are proven to pose unnecessary and avoidable harm to onsite employees. De-risk a site with an accurate, supportive tool designed to protect workers from harmful asset strikes.

he Safety Shovel provides the ideal real-time detection of metal and power above or below ground. It allows for the detection of metallic cables, pipes and electric circuits under the ground. The significant financial cost and time as well as reputational harm in the event of unexpectedly damage to utility assets can be crippling. In addition, industry demands for work safety have never been more stringent. The Safety Shovel is a key tool to prevent assets strikes and keep workers safe. The Safety Shovel is a world first, protected under patent after four years of persistent research and development. This tool is simple and easy to use. It provides the double benefit of serving as a conventional shovel and a safety tool/asset detection device in one. The Safety Shovel is multi-functional: featuring multiple sensors, it can detect a variety of metals within 280 mm. Heavy duty and lightweight, this tool is designed with the end user at the fore. The metal LED lights will flash green or red at a range in frequency from fast to slow to indicate risk during the dig. The long-life battery is USB rechargeable, and a single charge produces around 36 hours of use. The Safety Shovel is designed and made in Australia to be used as a supportive tool to protect workers from harmful events resulting from assets strikes. Although best endeavours are deployed to prevent infrastructure strikes, records that are inaccurate deliver risk that cannot be minimised without advanced tooling. The Safety Shovel provides the ideal real-time detection tool to protect workers by detecting metal objects & electrical cables (EMF) subsurface. In alignment to Australian excavation standards, the Safety Shovel allows workers to operate within the ‘exclusion zone’ and detect materials and cables that if damaged, would result in a major occupational health, safety and environment (OHSE) event. This technology is a world-first, incorporating simultaneous detection of electrical currents and metallic objects combined within a shovel, and it will make its debut at the 2022 No-Dig show.

More than just a supplier

As one of Australia’s leading equipment suppliers for sewer and plumbing equipment, Sewer Equipment Company (Aust), better known as SECA, is committed to providing quality parts and services, backed up by years of experience.

stablished in 1967, SECA is a top Australasian distributor of international CCTV brand iPEK and promises to deliver a solution that gets workers back on the job as soon as possible.

mart Lock is a no-dig point repair solution that reinstates the structural integrity of deformed and damaged gravity sewers and pipelines. Combining the benefits of fibreglass patching and 316 stainless steel, the repair system is designed to last in assets for 100 years. Smart Lock can be used in pipes ranging from DN100 to DN900. Smart Lock combines proven mechanical and fibreglass technology, with a smooth ratchet locking mechanism from which the product takes its name, to create a true structural fit within an existing pipeline. Installation is faster and more affordable than traditional repairs, taking less than 30 minutes and requiring only 94 TRENCHLESS AUSTRALASIA FEBRUARY 2022

three simple steps: load, lock and leave. Smart Lock can be used in repair jobs that would otherwise require costly bypass pumping and site management. Effective against root intrusion and compatible with end-to-end relining systems, the trenchless system can be used with all stormwater and sewer pipe materials to extend the life of assets by decades. “With three external locking mechanisms combined with one of the most trusted patch methods using silicate resin-impregnated fibreglass, it is not surprising that Smart Lock is the gold standard for trenchless point rehabilitation and the preferred solution for forward-thinking drain engineers,”

says Smart Lock Business Development Manager Shane Curren. “The system is ideal for pipe defects: from a rolled rubber ring, to a hole or a simple crack in a pipe. With a short cure time and guaranteed long life, it’s the logical solution for restoring weathered infrastructure.” Smart Lock can be installed remotely from an access pit, where it is loaded and held on the unique installation trolley. This method is faster and lower risk for the asset owner and rehabilitation contractor. The Smart Lock range also includes large bore drainage pipe seals which are designed for sewer and stormwater pipes with large diameters

Veolia is futureproofing assets for tomorrow Veolia provides a comprehensive service offering that caters for all aspects of network management while minimising impacts to the environment. The company has committed to accelerating the development of new solutions with ecological transformation at its core.

eolia designs and provides gamechanging solutions for water, waste and energy management. These complementary business activities allow Veolia to provide access to, preserve and replenish resources. Veolia is a global leader in water technologies, and in Australia and New Zealand offers practical, high-impact solutions for a range of network issues faced by councils, water utilities and municipalities, to increasing operational efficiency and offering specialised solutions to a range of asset problems. The company helps to improve customer service by delivering value across all stages of the water cycle, actively working to prevent climate change and protect biodiversity, all while enabling humans to continue to thrive.

Mission statement Veolia’s water division comprises over 830 employees across Australia and New Zealand. Daniel Spiller is the company’s Chief Operating Officer for Water. According to Spiller, ecological transformation is at the core of the company’s modus operandi. “We believe there is a global climate emergency, and that it is the responsibility of companies such as ours to lead the way in practical solutions to that emergency. This is what we term in our mission statement as ‘ecological transformation’,” says Spiller. “Within the water space, there is a real challenge of an ageing asset base, with many pipes constructed in the early 20th century now reaching the end of their service life. From our perspective, there is a real element of ecological transformation in getting the most out of those

New capability While Veolia has been active in Australia and New Zealand in network services for some time providing data analysis and modelling, inspections, condition assessments, maintenance, and pipeline rehabilitation and renewal using trenchless technologies, the company has recently strengthened its capability, launching a new solution: Thermoform PVC fold-and-form technology. This reaffirms Veolia’s offering as one-stopshop to water municipalities, councils and other clients. “What we’re doing now is strengthening our ability to help councils and water utilities rehabilitate assets to get more life out of them through a PVC fold-and-form product, which is cost effective and produces consistent highquality results,” explains Spiller. Thermoform is a new pipeline rehabilitation system for different diameter pipes, specialising in pipeline diameters DN150 to 300. Ziad Bushnaq is Veolia’s Market Development Manager. According to Bushnaq, flexibility of this solution not only offers a non-destructive trenchless approach, but it also provides a range of added benefits. “It is fit-for-purpose to suit different pipe sizes, wall thicknesses and conditions. It is moldable and provides a secure mechanical tight fit to the host pipe, minimising the reduction of the inner diameter of the host pipe and therefore improving the hydraulics of the rehabilitated pipe. With this solution, we can also eliminate the need for junction sealing,” says Bushnaq. The liner installation and removal process for the Thermoform system is significantly lower, reducing downtime to businesses and councils. The liner also extends the life of the assets by 50 years, preventing any spillage that

would otherwise contaminate the surrounding environment. “Introducing this service marks an addition to our network services capability that will allow us to provide an end-to-end solution for clients’ underground assets,” says Bushnaq. Despite the newness of the technology, Veolia has trialled and tested the system extensively. “We started with a trial in Tasmania, and another in Victoria in 2020, which included 500 m of DN150 sewer that required relining. We completed this trial to determine product suitability and success. Based on this trial, the results were positive and demonstrated a seamless installation of the process. “When we looked at the post-installation CCTV inspection, we determined that the final product quality exceeded the market expectations and that all host pipe problems have been resolved.” Following the trials, Veolia launched the product and capability in 2021 and became the official partner of Downer to deliver the Greater Western Water sewer renewal program which commenced with the relining 1.1km DN225 and DN150 diameter pipelines. The company has also been awarded a contract by Tweed Shire Council to rehabilitate aging assets using the PVC Thermoform technology. Works will also include sewer cleaning, pre- and post-CCTV inspection, civil works, sealing of lateral connections, traffic management, flow management, and, very importantly, customer and community engagement activities. Ecological ambitions Veolia aspires to reduce its footprint and exert a positive impact on the environment. As a result, the company makes commitments to decarbonisation and minimising

environmental impact. “Australia is at a pivotal point in terms of network management. We have an increasing population and a range of challenges facing infrastructure. To make that work, we need to innovate and work with utilities to find practical solutions to the problems they are facing. What we’re doing with Thermoform is part of that holistic solution, that suite of products,” says Spiller. This most recent capability is consistent with the company’s manifesto for ‘ecological transformation’ by extending the lifespan of existing infrastructure and mitigating the need for open-cut methods of installation. Moreover, the Thermoform technology eliminates water wastage and environmental contamination. “Old pipes leak, so rehabilitating networks helps stop the infiltration and exfiltration, and therefore significantly reduces potential soil and groundwater contamination,” Spiller explains. “It also means the material doesn’t contain chemicals that can leach into the surrounding environment. We work within an existing trench and we make the most of that. It is a safe product, and it has a relatively low impact compared to other products in a municipal environment.” The Thermoform PVC is a small-footprint solution to decontamination and asset degradation, creating a more resourceefficient infrastructure system that is effective and sustainable. Veolia will be exhibiting this new technology at the No Dig Down Under 2022 conference and exhibition taking place in March.

WaterAid: Transforming lives with their mission for clean water Since it was established in 1981, WaterAid has been fighting to improve sanitation and hygiene standards up across the globe. For the third time the organisation is No-Dig Down Under’s Charity Partner, meaning its goal to provide clean water for a healthier future is once again at the forefront of the event.

Rarua, from PNG, where 80 per cent of people live in remote location.

aterAid believes in the simple theory that without access to clean water, decent toilets or good hygiene, people can’t live dignified and humane lives, and that with these three simple assets, people can break free of poverty and positively change their lives, within our lifetimes. Operating in over 30 countries, including Australia, WaterAid says there are four reasons why its existence is pivotal to keeping people healthy in impoverished countries: • Without clean water, decent toilets and good hygiene being available to every person on the planet extreme poverty as inevitable somewhere in the world. • Different climates, geographical regions and experiences mean there’s no ‘one-size-fits-all’ approach to ending extreme poverty and providing clean water to those in need. • Toilets and good hygiene are critical to saving lives and ensuring dangerous diseases like diahrroea don’t spread at damaging rates. • WaterAid isn’t just important for using different techniques to extract clean water 104 TRENCHLESS AUSTRALASIA FEBRUARY 2022

but also works with partners to change laws, attitudes and behaviours while connecting policy makers to those in need. It is WaterAid’s techniques to tackling this momentous problem that makes them the ideal charity partner for No-Dig Down Under. They tap into groundwater, drill wells and harvest rainwater so people all over the globe can live, work and go to school. To continue the fight for clean water all over the world, WaterAid works with Corporate Partners to discuss new waterharvesting technology that doesn’t detriment the environment. These partners include leading proponents of trenchless technology, such as No-Dig Down Under sponsor Interflow and exhibitor KOR. While it’s members include the country’s leading utilities, such as Sydney Water, Yarra Valley Water, SA Water, Greater Western Water, Queensland Urban Utilities and Melbourne Water. As with previous years, the ASTT Gala Dinner and Awards Evening will raise money

for WaterAid and feature a presentation from WaterAid CEO Rosie Wheen, while various tap donation points throughout the exhibition will also help raise funds for clean water facilities in impoverished countries. Interested in getting involved? There are a number of ways Australasian trenchless businesses can provide technical and financial support to ensure those in poverty have access to clean water, decent toilets and good hygiene by 2030.

A Real Life Perspective on how Geotechnical Conditions Can Vary and Discussion of Risk Management Strategies to Deal With This

The Smart Linings for Pipe and Infrastructure Project researched the effectiveness of pipeline liners focusing on four product categories: CIPP and polymeric spray liners for water mains, and CAC and geopolymers for wastewater assets. The project installed products in field trials at utilities, undertook materials testing at universities and sensors to measure key attributes required for quality control were designed, prototyped and field tested. The project has delivered a foundation to ready the water industry for the uptake of these products by providing Codes of Practice to detail product installation requirements, Product Standards to provide clear guidance on material requirements to utilities and product manufacturers, and tools to allow efficient decision making when incorporating liners into rehabilitation programs.

Even though there are significant benefits in utilising trenchless technology it brings its own set of challenges and risks that need to be appropriately managed for a successful outcome. Drawing on experience as a contractor, client and consultant, this paper discusses the various strategies that can be implemented to best manage these risks. It utilises real industry projects examples where unexpected ground conditions were encountered during the construction phase of HDD and microtunneling trenchless installation sections. These strategies encompass measures that can be put in place during planning, design, procurement and construction stages. Marjorie Valix

Evaluation of One-Part Geopolymer Mortar as Protective Sewer Coating for Sewer Assets

Utilities face challenges in managing assets, primarily due to the aggressiveness and complexity of asset deterioration. Strategies to manage sewer asset deterioration are limited by the lack of appropriate classification of environmental conditions and their relative corrosion impact. New research at the University of Sydney has led to the development of proposed levels of corrosion classification for wastewater environments. This will assist in supporting targeted decisions including asset prioritisation and selection of appropriate mitigation technologies such as protective coatings to aid long-term, sustainable planning of maintenance and renewal of concrete wastewater infrastructure.

The design requirements of enveloper pipe installations, or what is sometimes called a “pipe in a pipe”, often causes confusion among designers, installers, and asset owners alike. Often the design intent or purpose of the enveloper is not understood and there is confusion as to whether it is part of the temporary or permanent works. This paper explores the historical use of enveloper pipes, their purpose, how they might be installed, and what the design requirements are for both the enveloper and the product pipe, as well as a summary of different authority requirements in both Australia and New Zealand. The paper also looks at some interesting case studies on various enveloper pipe installations.

The aim of this study was to undertake a qualitative and quantitative comparison of the relative durability of various commercially available geopolymers under accelerated corrosion and field tests. Geopolymers (GP) mortars provide suitable protective coatings for sewer assets because of their superior acid resistance and mechanical properties compared to ordinary Portland concrete. Conventional two-part GP mortars are prepared by adding the two components, a liquid phase consisting of the alkali activator and corresponding alkali silicate and the solid calcium aluminate (CA) precursor to water. For field site application the use of highly concentrated alkali solution is not considered practical. This has led to the development of one-part GP mortars that with one solid component consisting of solid alkali activator, silicate and CA precursor that is added to water.

Collar Suitability and Joint Deflection for MTBM Tunnelling Appropriate jacking pipe collar selection can significantly influence the outcome and success of a microtunnelling project. Significant forces and loadings are experienced at the joints along a pipeline during installation which are subsequently experienced by the jacking pipe collar. Poor collar selection can lead to a damaged final product and significant increases in project time and cost. This paper discusses the collar suitability resulting joint deflection and damages of a recently installed new main sewer line project.

Surface Preparation to Promote Adhesion of Protective Cement Mortars on Corroded Sewer Assets

Assessing the levels of deterioration of buried pipelines is a significant asset management problem for most water utilities. The lack of asset condition information, particularly for old reticulation mains, compounds this problem, forcing utilities to adopt a reactive maintenance approach for their ageing assets. Water utilities typically keep records of different combinations of pipe and backfill information. Therefore, we use a three-step, modular approach compatible with a wide range of datasets to predict the level of deterioration for an old water main. The algorithms presented here have been incorporated into a webbased platform which is part of the CRC-P Smart Linings Project to assist utilities and practitioners to select suitable trenchless rehabilitation techniques for a pipeline.

In January 2020, McConnell Dowell Constructors (MCD) commenced the St Mary’s Bay Water Quality Improvement Project on behalf of Auckland Council Healthy Waters (ACHW). The project is multidisciplinary, not only involving the tunnelled pipeline, but also the construction of 3 large shafts, 500m of large diameter open cut pipework, a fully operational pump station and a 460m long 1.6m dia. This has required extensive construction planning to ensure Resource Consent compliance is met whilst also causing minimal disruption to residents. This paper describes the construction of the scheme, that once completed will see overflow events reduce to 20 times per annum, drastically improving water quality in the harbour.

The aim of this work is to establish the concrete substrate requirements to promote adhesion of the concrete mortar repair system and the corresponding surface preparation protocols. Rehabilitation of a deteriorated structure involves the removal of the deteriorated concrete and its replacement with a new material that will extend its design life. Cement mortars such as calcium aluminate cement (CAC) and onepart geopolymer (GP) achieve this by providing a barrier between the corrosive environment and the pipe substrate. For this study the protective mortars tested included two commercially available CAC and two GP mortars. The protective mortars were tested in corroding OPC sewer assets that has been in service for 18-81 years. Steven Nash

Management of AC Pipes Now and into the Future The Asbestos Safety Eradication Agency (ASEA) established the Water Pipes Working Group (WPWG) in 2018 as a forum to address issues identified in the 2018 report, case studies of asbestos water pipe management practices. The report recommended that a clear, nationally consistent approach to managing Asbestos Cement (AC) water pipes was needed. The WPWG developed the draft AC Water and Sewer Pipe Management Guidelines, that were endorsed in principle by Safe Work Australia in June 2021.

Effects of Temperature on Material Properties in Spray and Cured-in-Place-Pipe Liners

Utility Location Advances – Why Engagement with Asset Owners is Still Vital

Temperature plays a vital role in estimating the long-term properties of spray and cured-in-place-pipe (CIPP) liners, which are examined in design guidelines for relining. Temperature variation in pipelines should be known prior to installation of any polymer-based pipe or liner. This ensures that long-term properties can be assessed in the laboratory for known temperature fluctuations. This paper examines initial tensile testing conducted on a thermosetting spray liner and thermosetting CIPP liner at various temperatures. The effect of temperature plasticises the polymer material making it more ductile but can also reduce the tensile strength of non-reinforced polymer liners.

The City Rail Link (CRL) is a game-changer for Auckland. It is New Zealand’s largest ever transport infrastructure project. The CRL project will see two new railway stations constructed at Aotea and Karangahape and Mt Eden Station redeveloped and will extend the existing rail line underground through Britomart and eventually rise to join the existing western line at Mt Eden, via Aotea and Karangahape stations. One such major diversion is required for the wastewater conveyance at Mt Eden, where the new rail tunnels connect the CRL tunnels with the existing rail system. The design for this diversion comprises a DN560 PE10DR7.4 HDD installation, 450m long, at depths up to 27m below ground level with open excavation sections at each end.

Improvements in underground asset locating technology, data storage and GIS have led to higher expectations and reliance on these tools to safely manage excavations. While the advantages of these advances is not disputed, it is vital that locators and their clients understand their limitations, particularly for high risk assets. Despite technological advances, current GIS data for gas transmission pipelines is limited and the scale of the task to improve that data is significant. Accuracy of data is being improved by GIS data collection and storage from all types of physical location proving, and also by data from in-line pipeline inspection tools. While this improves alignment data, there is the more challenging aspect of updating and keeping depth of cover data current. Depth of cover is more difficult to accurately determine and can be altered by both natural causes and third party works which can change depth significantly. Unfortunately, third parties sometimes complete such works without the required authorisation of the asset owner, preventing such changes being recorded. John Monro

Artificial Intelligence Defect Detection and Condition Assessment This paper looks at the collection of data from recent defect detection and condition assessment projects. The outcomes of these projects has successfully demonstrated that artificial intelligence (AI) can meet the same level of service as humans at detecting defects, but also determined what additional factors should be taken into consideration for pipe grading maintenance activities. The current pipe inspection standards provide challenges for software and operators alike to adequately capture information from pipe inspections and make decisions on actions to take. This paper explores processes that can be used to achieve further insights from the information already collected by utilities and operators.

When it comes to deteriorating asbestos cement pipelines, the danger posed by exposure to asbestos fibres means that the normal trenchless option of replacement by pipebursting isn’t usually acceptable, and excavation and replacement requires extensive safety measures to be implemented. The Mountain Highway AC Water Mains Renewal Project demonstrated an alternative for the first time on a substantial project. Some 1.4 kilometres of DN100 AC water mains was lined by die-drawn polyethylene pipe using the Interflow Titeflow process. This paper will detail how issues associated with die-drawn polyethylene lining of such a small diameter were addressed and how the result of the project showed that this is a viable alternative for renewal of deteriorated asbestos cement water mains.

The underground construction industry is facing a workforce shortage. Contractors’ report having the work demand to staff up to six more underground construction crews if they could find enough workers. OEMs have taken note and are putting their resources into solving this problem through evolving HDD technology. While advancements and innovation in HDD technology have historically been rooted in improving machine power, today the focus is on jobsite efficiency. This paper will trace the evolution of HDD technology through the years, identify how it has supported the workforce and discuss how these advancements will carry the industry into the future.

In 2019, Hunter Water detected a leak on a trunk main that services a large proportion of the Lower Hunter Region in NSW. This main is required to maintain security of supply to manage the peak conditions over summer. The main is located adjacent to sensitive wetland areas and is directly underneath a critical arterial road. A traditional dig and renew methodology would have required partial shutdown of this road, causing significant traffic disruption in an already congested area of Newcastle (Shortland). The paper describes the project progression and shows the make-up of the installed Aramid liner as well as the functionality of the corresponding termination fittings.

This paper will focus on the many components involved in HDD installations which have the potential to negatively impact the condition of the anti-corrosion coatings of the pipe. Considerations, including details such as soil conditions, entry/exit angle, pipe size and length of the pull, among others, will be explained and quantified. Ultimately the paper will outline ways to calculate the anticipated risk and provide guidance on how to mitigate that risk.

Condition assessment of pressure water and sewer mains has become increasingly important over the past 20 years. In general, quantitative outputs are preferable, and those which have a direct relationship with failure modes of the pipe material are far superior. Grey cast iron and asbestos pipes are brittle materials, unlike steel and ductile iron, which are stronger and tougher, and can fail without a deterioration in condition. Commonly derived and used outputs, including average wall thickness, average minimum wall thickness and minimum remaining wall thickness are discussed in detail. The only one which is considered to provide a meaningful result is minimum remaining wall thickness. The primary reason for this is based on large variation of condition both within an individual pipe, and from pipe to pipe.

Melbourne Water Corporation (MWC) and Aqua Metro Services (AMS) are in a framework contract for the delivery of MWC’s Small Scale Capital Works Program (SSCP). The aim of the program, especially in the case of pipeline rehabilitation projects, is to restore and renew the condition of assets for local communities, maintain safe conditions, optimise community space, and build resilient resources to support a rapidly growing city. AMS places a continual focus on the implementation of innovative technology to provide sustainable construction design and execution. Quadex Lining System (QLS), featuring GeoKrete Geopolymer, is a large diameter pipe and maintenance hole renewal technology for cost-effective rehabilitation of water, sewer, drainage and industrial infrastructure.

The amount of wastewater being collected and treated has increased significantly as Auckland’s northwest residential regions have expanded. To cater for this future growth in Auckland and free up existing wastewater treatment plants, the NZ$108 million Northern Interceptor Wastewater Pipeline was proposed in order to redirect wastewater flows from Massey North, Whenuapai, Hobsonville, Kumeu, Huapai and Riverhead to the Rosedale Wastewater Treatment Plant, located on Auckland’s North Shore. The focus of this paper will be on project delivery. This project was one of the most significant HDD projects completed in the region, and was technically difficult requiring multiple interfaces with logistics, environment and simultaneous operations. Sydney Water’s Trial Project of New Technology to Assess Water Tightness of CIPP This presentation will focus on FELL CIPP testing at three (3) residential Sydney locations, including Balgowlah Heights, Chatswood, and Birchgrove. And separate benchmark testing conducted at Sydney Water’s Potts Hill training facilities. Current industry accepted standards and practices have limited CIPP liner assessment and acceptance to visual inspection only, typically using high-resolution CCTV cameras, with hydrostatic testing not recommended due to connection or tap reinstatement. However, Electro Scan’s use in recent CIPP liner studies by the Institute for Underground Infrastructure (IKT), Gelsenkirchen, Germany, found it a valuable assessment tool able to accurately locate and quantify pinhole leaks in newly installed liners.

Over the past five years, PROKASRO MECHATRONIK GMBH and Brandenburger Liner GMBH Co have collaborated to develop high tech sensors for controlling curing speeds and improvements in Liner Carrier materials. During the curing process these sensors monitor three critical aspects of the cure. If a malfunction arises during the curing process on any component, the technicians are alerted via panel illumination sensors and the technician is then prompted to stop the cure at that exact location. In addition, the protocol data is recorded live onto the hard drive for each cure. These advancements have ensured that cured in place (CIP) liners cured via ultra-violet (UV) light is now proving to be a consistently reliable method for asset rehabilitation.

In 2017, McConnell Dowell Constructors with McMillen Jacobs Associates commenced the planning and detailed design of a large pipe jacked tunnel beneath Auckland’s inner suburbs to house the final remaining Section 11 of the Hunua 4 Watermain. The tunnel was an ambitious alternative to the base scheme - the aim being to minimise the impact to properties, residents, businesses and commuters in these busy suburbs by minimising the open cut trenching and maximising the trenchless component. Other objectives included minimising ecological impacts and whole of life costs, achieving 100 year design life, and conveying the water without requiring pressure boosting.

Maintenance structures are an integral part of any tunnel system. For sewer systems, these maintenance structures (or “manholes”) enable the asset owner to access, inspect and maintain a sewer throughout its asset life. Over the past 5 years, Yarra Valley Water has embraced the use of fibreglass (or GRP) manholes on its larger branch and main sewers. These vary from conventional concrete manholes in in terms of safety, construction and maintenance benefits. They also present new operational and logistical challenges. This presentation explores the use of fibreglass manholes through the lens of the Lockerbie Main Sewer Project and includes key points of difference and considerations for designers, manufacturers, contractors, and Water Authorities when considering a full GRP sewer system.

Ageing pressure water main infrastructure represents a significant risk to Water Authorities throughout Australia and New Zealand (A/NZ). Asbestos Cement (AC) pipe makes up around 40,000 to 50,000km of these assets across the A/NZ region. Most of these AC assets are reticulation sizes (DN100/150) and, with an average life expectancy of around 60 years, represent a major financial, environmental and social risk as they come to the end of their service life. Recently, Unitywater partnered with Interflow to trial RediFlow® on 481m of DN100 AC reticulation pipe in the suburb of Narangba. This paper will walk through the trial from inception to delivery and share the results of this innovative process, which delivered a cost-effective solution with low environmental and community impacts as well as minimal asbestos exposure risk.

In slurry microtunnelling the slurry pumps are crucial components for long-distance drives. With the new Jet Pump technology drive lengths of over 1,000 meters can be achieved, even in small diameters. The jet pump technology, first tested with HDD, was integrated into AVN slurry microtunnelling creating the AVNS machine. Several applications benefit from this development, which this paper will discuss. Currently, the AVNS concept is being introduced in the Direct Pipe® technology to enable single-pass pipeline installation for long crossings down to 24 inches in diameter. Furthermore, Herrenknecht’s new small diameter AVN-Rock series with TCI cutters has been incorporated into the AVNS Direct Pipe® concept. Gary Johnson

Abstract

Introduction of New Technology for Small-Diameter Steel Pipe Extraction for Replacing Gas Services Today, many bare steel lines continue to operate although may be nearing the end of their useful life as the lack of a protective coating subjects the pipe to corrosion affecting its integrity. Gas utility owners have been proactively identifying and addressing pipelines in need of replacement. Reduced excavation is often more economical and less disruptive to utility customers, and utilizing the existing conduit greatly reduces the risks associated with relocating the line. In conjunction with other gas utilities facing similar challenges, HammerHead has developed a steel pipe extractor currently undergoing field trials producing consistent results. This presentation introduces the newly developed Steel Extractor system and the trenchless extraction process. It also reviews the R&D process including the progress of preliminary field testing.

Direct Pipe® in Three Case Histories – Overcoming Challenging Ground and Site Conditions Direct Pipe® (DP) is a relatively new trenchless technology by which a steel pipe is installed in compression through curves and sometimes tangent sections. The ground in the heading of the pipe is excavated through conventional microtunneling methods while a pipe thruster machine provides the motive force. Once the crossing is completed and the microtunnel boring machine is recovered, the installed pipe may be subsequently used as a casing for another pipe or as the product or carrier pipe. This paper will highlight three applications of the method from the authors’ experience with challenging geotechnical conditions and tight workspace geometry where HDD was considered but deemed infeasible. The project examples will be used to introduce and discuss engineering aspects of DP crossings such as geologic risk, methods for the assessment of steel stress, buckling risk, and hydraulic fracture risk.

All Weather Locating Beneath the Road – Improvements in Safety and Speed of Asset Mapping within Transport Corridors Infrastructure and construction delivery relies on rapid and accurate locations of existing underground assets. During recent adverse weather events underground asset locations were considerably delayed, setting back critical construction works. As most assets lie beneath active roadways, comprehensive asset locating requires significant traffic management and/or after business hours work, both of which come at increased cost and specific permitting and procedures. This paper provides a consideration of locator safety in the specific task of transport corridor asset mapping and evaluates practical tools and techniques that provide improved efficiency in adverse weather.

Abstract

Minimum Performance Requirements of HDPE Pressure Pipes Product and installation standards for HDPE pressure pipes have been established to ensure a target design life of at least 50 years under typical application conditions. It is essential that all actors involved in pipe value chain have a basic understanding of the minimum performance requirements listed in the standards and how conformance to the standards is assured. Failure to consistently meet the requirements may result in the structural integrity of the pipeline being compromised, service disruptions and ultimately a need for expensive replacement of pipe. As HDPE pressure pipes make their way into new applications, and new installation techniques emerge, additional requirements need to be considered to keep the target design life above 50 years. TK050 and TK2050 Deep Sea Tailings Re-Line During 2019, HDI Lucas commenced a three-year project in Papua New Guinea to remove and replace two DN1200 HDPE outfall pipelines, 190m and 236m in length. These HDPE outfall lines were set at 37 and 33 degrees respectively. The crew completed the works removing the HDPE in early 2020 before demobilising to design and implement a construction strategy to reinstall HDPE in place of the removed liner, and to remove and reinstall the sister line. The focus of this paper will be on project delivery. This project presented technical and managerial challenges due to the unquantified extent of the damage and condition of HDPE liner, the angle of operation, significant underwater operations and the remoteness of the operation.

Essential Considerations of Shaft Design and Construction for Microtunnelling Works

Advancement in the development of GPR systems now allows for rapid full 3D capture of underground assets using arrays of multi-frequency, multi-polarised GPR antenna which are either hand pushed or towed by vehicles. The “IQMaps” software, in conjunction with the IDS GeoRadar Stream UP and Stream C massive array GPR systems, is a specifically designed solution to assist the utility locating industry by not only providing accurate super-clear georeferenced subsurface utility imagery in real-time, but also to enable users to swiftly extract information from this imagery and delivery final results very quickly. This means that companies involved in large projects can now be provided with geo-referenced deliverables much faster than ever before, allowing them to make decisions without significant delay to operations.

Shafts are required on most trenchless construction projects and need to be treated with the same level of attention as other works. This paper intends to discuss the key elements that should be addressed during the early stages of shaft designs. This consists of risk reduction related to project geology, existing infrastructure constraints and construction programme. It includes the use of sustainable methods for design, the role of digital engineering and how integration between temporary and permanent works could be adopted to maximise project benefits. These points will be discussed using a number of pertinent project examples and lessons learnt.
