Editor’s letter Molly Hancock

elcome to the April 2022 edition of Trenchless Australasia. This edition focuses on the growing role trenchless technology is playing in reducing emissions from pipeline construction, rehabilitation, inspection, and maintenance. The issue contains specialised content focusing on the environmental benefits of no-dig methods, as well as the new technology which is already part of the energy transition. As the voice for the trenchless industry, the Australasian Society for Trenchless Technology (ASTT) formed a Special Interest Group (SIG) of leading industry professionals to create a solution that supports the mitigation of climate change impacts. Following the ASTT securing a deal with Mott MacDonald in August 2020, the council was able to access its Carbon Calculator to promote innovation in the trenchless technology sector. The Carbon Calculator was the first calculator capable of measuring the capital and operational carbon footprints of building information modelling (BIM) designed assets. The tool is set to be used to promote best practices across the industry, with it having three steps the calculator aims to take, including: 1. Reduction – reduce the carbon impact of infrastructure. 2. Behaviours – improve the behaviours of designers, constructors, and entire supply chains to reduce infrastructure carbon. 3. Union – create a common way of

working to calculate carbon reductions across the industry, setting the narrative. It is great to see a number of trenchless companies are actively taking steps to reduce carbon emissions and their plans going forward to continue enhancing their technologies to achieve this. June this year marks the first No-Dig Down Under conference in three years. Following the success of the September 2019 event held in Melbourne and due to overwhelming support from sponsors, exhibitors and delegates, No-Dig is coming to Sydney, hosted at the International Convention Centre. Organised in partnership with the ASTT, the event will feature a world-class conference program, with three conference streams all focused on different aspects of the industry; training courses on trenchless methods presented by industry leaders; and an exhibition extending over 4,500 sqm and featuring exhibitors from all sectors. The team here at Trenchless Australasia have even more themes to dive further into about the trenchless industry and provide insightful and thought-leadership pieces from the sector. Happy reading!

NEWS IN BRIEF

West Gate Tunnel TBM launches A contract to deliver the next stage of tunnelling on the Sydney Metro West project.

Sydney Metro West tunnelling contract awarded The New South Wales Government has awarded a $2.16 billion contract to deliver the next stage of tunnelling on the mega Sydney Metro West project. The Gamuda Australia and Laing O’Rourke consortium has been awarded the Western Tunnelling contract to deliver 9 km of twin metro rail tunnels between Sydney Olympic Park and Westmead. Premier Dominic Perrottet said this once-in-a-century infrastructure investment will link new communities to rail services, slash travel times across the network and support employment growth. This is the second major tunnelling package awarded on the cityshaping project, with work already underway to deliver twin tunnels between The Bays and Sydney Olympic Park following the contract awarded to Acciona Ferrovial Joint Venture last year. Work is well underway to ready the site for the arrival of the tunnel boring machines (TBM) at the end of the year. The NSW Government said completion of the contract is expected by the end of 2025. The Gamuda Australia and Laing O’Rourke consortium will deliver 9 km of twin metro rail tunnels between Sydney Olympic Park and Westmead.

Tunnelling on the West Gate Tunnel Project is off to a running start, with tunnel boring machine (TBM) officially launching into action. The project is being delivered in a partnership between the Victorian Government and Transurban, and will be built by construction contractors CPB Contractors and John Holland. Contractor John Holland said TBM ‘Bella’ has begun its 18-month journey to carve out one of the twin tunnels that will create a vital alternative to the West Gate Bridge. According to John Holland, ‘Bella’ is the biggest TBM currently in operation in the southern hemisphere. With a cutting diameter of 15.6 m, it will take a crew of 20 to operate the machine. Excavation on the 4 km tunnel will continue around the clock, with crew working in shifts, seven days a week. In a few short months, a second John Holland TBM, ‘Vida\’, will start digging the 2.8 km inbound tunnel. The West Gate Tunnel Project will deliver a much-needed second river crossing, reducing congestion, and clearing thousands of trucks from residential streets. Set to become one of Victoria’s largest ever urban road projects, it has an estimated completion date of 2025.

Repairs scheduled for SA’s longest water pipeline After nearly 80 years of service, South Australia’s longest water pipeline is gearing up for a major renewal. In the next few months, up to 34 km of the Morgan to Whyalla Pipeline will be replaced as part of a $62 million investment securing reliable water services for 100,000 regional customers. Built in 1944, the pipeline begins at the Morgan Water Treatment Plant, from which it stretches 358 km to deliver safe, clean drinking water to homes and businesses across the Mid North, Yorke Peninsula and Eyre Peninsula. SA Water’s general manager of sustainable infrastructure Amanda Lewry said new sections of pipeline will be constructed in parallel to the existing infrastructure, to minimise interruption to customers’ water supply. 14 TRENCHLESS AUSTRALASIA APRIL 2022

NEWS IN BRIEF

Hunter Water debuts new trenchless tech

Iplex Australia appoints new general manager

Hunter Water is debuting an innovative new ‘keyhole’ technology for restoring damaged or degraded pipes in the Lower Hunter community. Crews are using the European technology on four projects around the region to create an internal lining within the degraded pipes, or as the utility describes it, a ‘pipe within a pipe’. The structural liner is ideal in sensitive and difficult-to-access areas, and has been used to extend the life of Hunter eWater’s mains while minimising disruption to the community. Hunter Water managing director Darren Cleary said the organisation is always improving how it accesses and manages the condition of infrastructure across its network of more than 10,000 km of water and sewer mains. Hunter Water has used the technology to complete several projects throughout Lake Macquarie.

Building for a better future The last 12 months has been an interesting period for the trenchless technology sector in Queensland. An unprecedented infrastructure boom has marked a milestone in Queensland’s economic recovery in the wake of COVID-19.

n July 2021, the historic announcement was made that Brisbane would host the 2032 Olympics after a vote by International Olympic Committee. The announcement triggered a series of development and infrastructure projects to lay the groundwork for the world stage. Infrastructure projects across the state are still on the rise, driven by a strong pipeline of engineering and heavy civil construction work, underpinned by vast investment from the Queensland Government. These big builds are intended to bolster confidence, generate jobs, and guarantee economic growth for the state. In other firsts, Queensland has identified priority industries in the resources and energy sectors, including the production of hydrogen and biofuels, as well as the infrastructure to support it. Queensland will be home to Australia’s first renewable hydrogen production facility in Gladstone, with backing from Andrew Forrest’s Fortescue Future Industries (FFI). This widespread uptake of hydrogen in Australia will require storage, and underground hydrogen storage via tunnelling is the preferred option for reasons of both cost and safety. While the industry is still embryonic,

The Story Bridge in Brisbane City.

18 TRENCHLESS AUSTRALASIA APRIL 2022

Queensland has made some significant steps to secure its future as a hydrogen superpower, having signed agreements with FFI to connect sites near Gladstone to Powerlink’s transmission network to allow renewable electricity to power proposed hydrogen projects. ENEOS - Japan’s largest oil company - is set to significantly increase its production of green hydrogen in Queensland with a target of 20 kg/d. The following trenchless feats have been accomplished in transport, water, and energy over the last year. Cross River Rail The Cross River Rail project is a new 10.2 km rail line from Dutton Park to Bowen Hills, which includes 5.9 km of twin tunnels under the Brisbane River and CBD. It is the most ambitious infrastructure project Queensland has seen in decades. As South East Queensland’s population is rapidly rising, current rail infrastructure is already nearing its capacity, causing bottlenecks and congestion on trainlines. SEQ’s network is constrained by a single river crossing and just four inner-city stations, and the Cross River Rail will resolve the issue by delivering a

second river crossing and new systems across the region. In 2021, Cross River Rail embarked on its year of tunnelling that saw two massive tunnel boring machines (TBM) dig twin tunnels beneath the Brisbane River and CBD. TBMs ‘Merle’ and ‘Else’ are each 165 m long and weighing 1,300 t, named after trailblazing engineer Professor Else Shepherd and pioneering feminist Merle Thornton. Both began their journey from the Woolloongabba station box at the start of the year. From there, the pair made their 3.8 km journey underground, emerging from the project’s northern portal at Normanby before Christmas. Meanwhile, two 115 t roadheaders excavated the almost 900 m of twin tunnels south from Woolloongabba to Boggo Road. For the first time ever, Roma Street and Woolloongabba are now connected underground. Build Our Regions Program The Building our Regions program has a long and successful history of supporting Queensland’s local governments to invest in essential regional infrastructure and creating

flow-on economic development opportunities and jobs. Round six of Building our Regions, announced by the Palaszczuk Government September last year, will offer $70 million over three years for local governments to improve their water supply and sewerage systems. Until 17 May 2022, Councils can apply for up to $2 million in funding to support a range of eligible construction and works projects over three years. All local governments outside South East Queensland are eligible for funding through Building our Regions Round 6. Previous rounds of the program have seen more than $348 million approved towards 271 projects across 67 local government bodies. Projects have included 8 km sewerage pipeline replacement for Bundaberg Regional Council and a new 800 m water bore for Murweh Shire Council. $2.1 million West End main replacement Townsville City Council awarded a $2.1 million contract to replace around 1.3 km of water main along Stagpole Street in West End using trenchless methods. The ageing pipeline is nearing the end of its working life, and local contractor CityPlus Construction was awarded the contract to commence replacements in November. Townsville Mayor Jenny Hill said the local council is committed to upgrading civil water infrastructure across the city to ensure quality

water service into the future. “In the 2021/22 Budget, Council dedicated $177 million towards maintaining, upgrading, and delivering water infrastructure and services to the community,” Cr Hill said. “This investment allows us to prioritise the replacement of mains nearing the end of their operational life and ensure that the city has a secure water supply as our population grows.” The works are also expected to support the local economy by providing ongoing work to businesses. Townsville Water and Waste Committee chairperson Russ Cook said upgrading the pipes is a timely and necessary endeavour. He added that trenchless technology will be used to minimise disruption to the surrounding environment and local community. APLNG proposes HDD for gas wells Australia Pacific LNG (APLNG) said it will use horizontal directional drilling (HDD) in its proposed gas expansion to avoid disturbing the local environment above ground. In April 2021, a joint venture (JV) between Origin Energy, ConocoPhillips and Sinopec, APLNG sought federal approval to drill thousands of new gas wells in Queensland as part of its Gas Supply Security Project. In its referral documents, APLNG said it would construct the wells using HDD and would also incorporate this technology for drilling of pipelines under threatened ecological

communities, threatened flora, threatened fauna habitat and migratory fauna habitat. The JV cited forecast gas supply shortfalls from 2024 onwards as reason for undertaking the new drilling activity, as well as the potential for increased gas demands and increased reliance on Queensland supplies as production from Victoria continues to decline. The new gas would be used for both the domestic gas market and the export demands of APLNG, with current appraisal data showing production from 2P resources expected to be 453.6 PJ of gas. If the proposal is successful construction is likely to commence in 2024. Seqwater completes water pipe upgrade In June last year, the utility undertook a $1.5 million upgrade of two important water pipelines in Queensland. The pipes supply water from the Mount Crosby Treatment Plant to Brisbane and Ipswich. The works involved taking a 4 km section of the pipes at Barnes Hill offline temporarily to replace four valves which are reaching the end of their service life. Minister for Water Glenn Butcher said the work will support the ongoing supply of safe drinking water for the region and improve the reliability of the SEQ Water Grid.

EMISSIONS REDUCTION

The AST created a SIG to look at the impact trenchless technology has in reduction carbon generation in construction projects.

Carbon Calculator key to reducing trenchless industry emissions There are a number of reasons why trenchless technology is a sustainable and green alternative, with the technology in the industry aimed at reducing the carbon emissions generated.

ot only is trenchless works typically more time efficient than open cut alternatives, meaning that machinery is operated for shorter periods, but traffic fuel consumption is lowered by trenchless methods. By avoiding traffic disruptions, trenchless projects prevent the delays and detours associated with conventional underground infrastructure projects. This lowers the amount of petrol consumed, and subsequently reduces carbon emissions. In addition, according to a study conducted for the North American Society for Trenchless Technology (NASTT) by the University of Waterloo, located in Ontario, Canada, it found that trenchless job sites produce fewer emissions. They require minimal construction machinery and equipment as there is no need for excavation, compaction, backfilling and re-paving, dramatically reducing fuel consumption. With the industry focused on preserving the environment and reducing emissions, the ASTT created a Carbon Calculator to promote innovation in the trenchless technology sector. The purpose of the ASTT is to advance the science and practice of trenchless technology for the public benefit, while promoting education, training, study and research and practice for the public benefit and to publish the useful results of the same. With this in mind, paralleled with the

20 TRENCHLESS AUSTRALASIA APRIL 2022

global goal of reducing carbon emissions, the ASTT formed a Special Interest Group (SIG) of leading industry professionals to create a solution that supports the mitigation of climate change impacts. ASTT Councillor Matthew Boyle says the ASTT embarked to create a SIG to look at the impact trenchless technology has in reduction carbon generation in construction projects. “The SIG’s purpose was to provide members with access to a Carbon Calculator to quantify, and therefore promote, trenchless technology as a lower carbon emissions alternative to Excavate and Lay,” he says. “The primary focus of the SIG was to provide members a tool to compare greenhouse gas emissions using comparative approaches in the capital delivery of services.” As a result, the SIG approached the market for the development of the calculator and selected the Moata Carbon Portal from Mott MacDonald in August 2020. At the time of release, it was the first carbon calculator capable of measuring the capital and operational carbon footprints of building information modelling (BIM) designed assets. Boyle says following Mott MacDonald agreeing to be on board with the ASTT, the SIG moved into trial phase where asset owners were selected to use to the tools in their businesses for best use practices in Australia. However, it was here where the process stalled and the use of the calculator in the trial

was limited, little feedback was submitted, and the pandemic hitting Australia. Boyle says the SIG has currently been suspended until further legislation and member support. “We went with Mott McDonald because in New Zealand there is a legislative requirement to monitor carbon emissions, but until there is something in place like this in Australia, the SIG has come to a halt.” In December 2021 the Australian Government released the June 2021 quarterly update of Australia’s National Greenhouse Gas Inventory. Australia’s greenhouse gas emissions fell by 2.1 per cent in the year to June 2021, and have fallen by 20.4 per cent since 2005 Boyle says he sees the awareness of carbon emissions driving the trenchless community to look deeply into its supply chain to innovate and come up with new techniques and products to drive zero emissions further into the future. “I see the specification of low emitting trenchless technology by asset owners and government organisations to be the standard across Australia and New Zealand,” he says. “I believe this will be backed up by legislation and the trenchless community will be well placed to help deliver on a low carbon future.” With the trenchless community already doing its part to reduce emissions, Boyle says the rehabilitation process for overall asset installation can be measured, quantified, and

part of the process emits more carbon, allowing innovation to occur to eﬀect overall emission reduction,” Boyle says.

EMISSIONS REDUCTION

Rob Carr continuing to take steps to reduce carbon footprint Rob Carr has a longstanding commitment to reducing the company’s carbon footprint, dating back more than a decade. More recently, the company has taken actions to be more environmentally efficient in three key areas.

missions reduction is arguably the most significant topic for debate in the community and has been for some time. It is now apparent that all individuals and organisations have a role to play in taking responsibility and being conscious for their carbon output and making changes where they can. Leading the way for a decade Rob Carr is proud to be leader in the research and development of microtunnelling and other trenchless technologies in Australia and New Zealand. Back in 2012, the company supported research into how microtunnelling could be used to reduce emissions – the learnings of which were subsequently put into practice. Through the Griffith School of Engineering, Rob Carr Project Manager Jaime Leal undertook an investigation into the emissions generated from trenchless versus conventional open cut methods. The purpose of the research was to compare the carbon footprint of microtunnelling, based on data from a number of projects carried out by the company, with projects which used conventional construction methods. Mr Leal’s research found the emissions produced by microtunnelling was dependent on the size of the microtunnel boring machine (MTBM) and the soil conditions, while emissions from conventional construction were strictly related to the depth to invert level of the installation. The main comparison, where both construction methodologies comprised an identical scope, included a 3.5 m deep invert level pipeline in sand, sandy clay and gravel. The microtunnelling method was established to produce only 47 per cent of the amount of CO2 emissions produced by open cut. The thesis also found the fuel consumption of microtunnelling was dependent on geology and the tonnage required to push the MTBM thorough the ground. As a result, concluded that at a depth of 1.9 m – in clay, sand or gravel – microtunnelling became more economical and was the 22 TRENCHLESS AUSTRALASIA APRIL 2022

most advantageous technique for pipeline installation. Environmental action plan In 2020, Rob Carr’s parent company, Soletanche Bachy, mandated that all of its subsidiaries around the world would be required to produce an Environmental Action Plan designed to reduce emissions by 40 per cent by 2030. It was stipulated these plans had to target three key areas of improved efficiency: fuel, electricity, and water. To meet these objectives, last year Rob

Rob Carr aims to to reduce its emissions by 40 per cent by 2030.

Carr installed solar power generation at the company’s warehouses in Yatala, Queensland and in Welshpool, Western Australia. In addition to office space, at Yatala the system had to be designed to cater for an onsite fabrication facility which uses a considerable amount of power. A 39 kW system is now in place, featuring 128 solar panels, with approximately 4 kW of redundant power directed back into the grid. In Welshpool, a 9 kW system made up of 24 panels was installed and in 7 months of operation has reduced emissions by 6.76 t. To tackle fuel reduction, Rob Carr’s fleet of generators has been updated with newer and more environmentally beneficial technology, while the company is also looking at introducing transformers on site and reducing the use of light vehicles on projects. In Yatala a more than 20,000 l rainwater tank has been installed under the warehouse, while water recycling processes are also in use. “The results of our Environmental Action Plan will be assessed at the end of this year, at which point a new plan featuring new steps will be introduced,” says Rob Carr Safety, Health, Environment and Quality Manager Mark Fee. “These plans need to be assessed regularly to ensure we know how we’re tracking against our goals. The early indications are that we are already exceeding the expectations set out by our parent company, are on track to exceed our 2030 target, and are committed to going further than that in the future.”

The key to long-lasting plastic pipes and ﬁttings Playing a vital role, plastic pipe systems deliver essential everyday services from civil and domestic infrastructure to agricultural, mining and gas. PIPA’s sustainability story To help educate across a wide range of audiences, PIPA has developed key messages to tell its sustainability story. Not all plastics are the same and too often pipe systems are mistakenly put in the same category as single use plastics.

PIPA represents manufacturers and suppliers of plastic pipes and ﬁttings.

he Plastics Industry Pipe Association of Australia (PIPA) was founded in 1999 and is the peak industry body representing manufacturers and suppliers of plastic pipes and fittings, plastic resin suppliers, fabricators, pipeline installers, rubber seal ring manufacturers along with training and certification bodies. As a non-profit association, PIPA works to promote the appropriate and contemporary use of plastic pipes and fittings throughout Australia. This is achieved through our four key pillars of advocate, educate, technical and sustainability. Executive General Manager Cindy Bray says Australia’s vast landscapes require largescale, special purpose systems to move water, wastewater, gas and to protect underground networks of power and communication cables. “We know that potential that plastic pipeline systems provide for long life, sustainable infrastructure that supports the circular economy,” she says. “Not only are plastic pipes smart, eﬃcient, and sustainable but so are the trenchless installation methods used. Plastic pipes are the 24 TRENCHLESS AUSTRALASIA APRIL 2022

preferred choice to replace and upgrade other pipes throughout the world. This is due to their performance, durability, service life, simplicity of installation, energy eﬃciency, recyclability, and overall cost effectiveness.”

PIPA says pipes are long-life products made from materials engineered to be robust, reliable, and recyclable.

Plastic pipe systems deliver essential everyday services and utilities When thinking about the network of pipelines under the ground there are many vital roles they play from delivering drinking water, gas and electricity to homes and communities. Bray says the network of wires and cables that deliver internet and communication services are used in irrigation systems that are essential for growing food. Plastic pipes also carry away sewerage, rainwater, and stormwater – protecting communities. “In recent years the water industry has also embraced PE particularly when trenchless installation techniques like directional drilling, pipe cracking, slip and swage lining have led to increased usage in water and wastewater applications,” she says. “These allow for fewer disruptions during installation or repair of existing pipelines, allowing flexibility and cost-

effective installation of pipelines without the need to excavate trenches, lowing the impact to the environment and the community.” Engineered products designed to last Plastic pipes are long-life products, not singleuse and are made from material engineered to be robust, reliable, and recyclable. With a service life longer than 100 years, the pipes are engineered from polymer materials and the perfect choice for infrastructure applications. Unlike many plastic packaging applications which have multiple layers, plastic pipes are made from a single material and therefore easier to recycle. “Plastic pipes used in buried infrastructure

applications, like water, will likely never be dug up even at the end of their long service life. Instead, they will likely become a host for a new plastic pipe through trenchless installation, saving huge amounts of energy, resources, significantly reducing the impact to the environment,” Bray says. Safe for people and the planet Plastic pipes provide the highest level of safety for carrying drinking water and are manufactured to Australian standards. Offering clear advantages in terms of chemical resistance over other pipe options, they are not affected by soil environments that are highly corrosive to metals and concrete.

Plastic pipes are not affected by compounds that form in wastewater such as acids that rapidly degrade iron and cement-lined pipes, making them the ideal choice for long-term infrastructure. “Using plastic pipe systems in trenchless applications minimises the environmental footprint and is the best choice for digging under creeks, rivers, and other environmental sensitive areas,” Bray says. The smart choice, using recourses responsibility and sustainability Most plastic pipes are still in its first lifecycle and therefore recycling rates remain low, with most buried infrastructure applications becoming host pipes, minimising the impact to the environment using trenchless installation. Bray says life cycle analysis studies have shown plastic pipes have a significantly better environmental profile than alternative pipe materials in all categories and across its whole lifecycle. Trenchless technology installation also reducing carbon footprint, reducing energy use and the amount of pollution released in the atmosphere compared to open cut trench. “You can see the environmental benefits of using plastic pipe systems with trenchless installation methods. By using resources responsibly through better design, we’re working smarter. We’re committed. And we’re working towards creating a healthier environment and sustainable future,” she says.

arra Valley Water has successfully delivered the Doreen to Diamond Creek Sewerage Project after two years of construction works. Design works commenced in February 2018, with design consultant Jacobs contracted to discern if there were any culturally significant artefacts on the banks of the Plenty River. Jacobs found close to 400 aboriginal stone artifacts over an area of several hundred metres, after which the contractor consulted local Wurundjeri to negotiate a different construction technique to the traditional open-cut excavation method. Horizontal Directional Drilling (HDD) was deemed the most viable solution to protect the archaeological site from harm. As most archaeological artefacts are located within the top 50 cm of soil, trenchless technology can effectively bore while avoiding disturbance to any culturally significant sites. As well as retaining cultural significance, reducing the need to excavate helped to maintain the integrity of the ecosystem. Yarra Valley Water was careful to ensure that works did not affect water or sewerage services in the area. Construction works commenced in March 2019 and were completed in November 2021. The project involved the installation of approximately 10 km of pipe and 17 new sewer maintenance holes under parkland and road reserves in the Doreen, Yarrambat and Diamond Creek areas. The new sewerage infrastructure will service properties in the rapidly expanding

Adept completes bore for Sunbury Line Adept Civil has completed another rail crossing out at Keilor Plains for Multiworks as part of the Sunbury Line upgrades.

dept Civil was contracted by Multiworks, who has partnered with Metro Trains Melbourne (MTM), to deliver major upgrade works at the Tottenham Substation as part of the Sunbury Line Upgrade and Metro Tunnel Projects. The scope of the project was to tunnel using a micro-tunnel boring machine (mTBM) under the Sunbury Line during an occupation for Multiworks. “Great results out at Keilor plains substation, delivering yet another complex and critical rail crossing,” microtunnelling supervisor Maddison Corrie says. Adept installed a 376 mm GRP sleeve to carry 2 x 100 mm conduits for the power upgrades, which are taking place in and adjacent to the rail corridor as part of works to boost electrical capacity along the Sunbury Line. As part of the upgrades, an electrical substation on Sydenham Rd Delahey is being built to provide essential power for bigger, more modern trains to run along the line. The Sunbury Line Upgrade includes power upgrades that will allow bigger, more modern trains to run on the Sunbury Line. An extension to the existing electrical substation at Tottenham station is required to improve the capacity, reliability and frequency of services for passengers. The new trains are a vital component to the expansion of Melbourne’s metropolitan rail network, and will greatly improve the capacity, reliability and frequency of Sunbury Line train services. Adept successfully completed the 15 m bore on-line and grade with the axis boring machine, using a 400mm tricone rock head in extremely hard basalt ground conditions. The $2.1 billion Sunbury Line Upgrade will see various upgrades within the rail corridor extending from Sunbury to Footscray. These enhancements are needed to take full advantage of the extra capacity created by the Metro Tunnel and for more modern trains to run on the Sunbury Line.

Sydney’s forgotten ghost tunnels all powered up with guided boring breakthrough Directhitt Trenchless has completed a project for Laing O’Rourke at Sydney’s Central Station by installing critical electrical infrastructure for the new Sydney Metro.

s part of the biggest upgrade to Sydney’s busiest railway station in decades, Directhitt Trenchless were contracted to supply and install four DN 630 HDPE liners and PVC electrical conduits to provide 33KV power to the new underground Metro station. The boreholes constructed by Directhitt, connected the 27 m deep metro station box level B2 to an existing ghost tunnel, which was built in the 1920s as part of the Eastern Suburbs Railway line for Bondi and the Illawarra. However, it was never completed. Platforms 26 and 27 have sat unused since and will now house 17 new communications and power rooms to support the new Sydney Metro at Central Station. The 90 m long microtunnells were constructed using an Akkerman Guided Boring Rig, which used a Pilot Tube and Laser Guidance System to accurately drill the pilot hole to line and grade in Class II Hawkesbury Sandstone.

Directhitt chose to use a Guided Boring rig with a compact 3 m jacking frame for the project.

The confined site prevented the use of a typical HDD rig set up, so Directhitt chose to use a Guided Boring rig with a compact 3 m jacking frame. The Akkerman dual-wall pilot tube design allows the pilot tubes to be installed with

pipeline space. Doug Walker is one of the Civil Project Supervisors at TI and has been working with the business for about two years. He says the decision to expand into civil work was made because it offers a big opportunity for growth. “There was a lot of work going in council pipeline projects, watermain replacements, and building out pump stations, so we have invested and grown that part of the business

over the last few years,” Doug says. Part of that growth has seen TI recently add a brand-new Vermeer D8x12 HDD to its fleet of excavators and skid steers, which will be put to work on the smaller jobs that would usually be contracted out. “It’s been hard to contract out our small, local jobs lately, as the labour and appetite just isn’t there. So, we decided to invest in the business, bring in a machine, and train ourselves up so we could do the work ourselves,” he says. The Vermeer D8x12 HDD offers the strength of a large drill with the compact body and enhanced performance of a small drill. The D8x12 comes with straightforward controls, a narrow footprint and enhanced power with less sound disruption, and is ideal for small service installation, such as gas distribution, power, water, and telecommunication networks. Walker says that before the D8x12 is put to work, he and the team will finish their training on the drill, provided by Vermeer Australia. “We’ve organised five days of training on the new rig, to get us across how to best use it, and the safety features. Then we’ll be putting it to work first on under road boring work in the local area,” Walker says. “The Vermeer Australia team has been

great, and a special thanks to our rep Kevin and the Albury team here. They’ve really supported us in our first purchase, making sure the team is comfortable with the drill, and answering any questions we have. Once we put it to work and see how it performs, we may look at adding another one to our fleet in the future.” For more information visit: www.vermeeraustralia.com.au

Powerful pumps – the heart of HDD maxi-rig spreads It’s common to think of horizontal directional drilling (HDD) spreads in terms of rig size, but the true workhorse is in fact the mud pumps – a high efficiency positive displacement piston pump. Without it, drilling fluid cannot be pumped into the bore to the jet or motor drill, and the bore would not have any stability.

f the pumps are down, the drilling stops In the Australian HDD sector there is a limited number of available maxi-rigs and powerful mud pumps. Having ready access to additional maxi-rigs and powerful mud pumps is a key means to maintaining project productivity and mitigating the impact of unscheduled repairs. If the pumps are down, the drilling stops. Mud pressure is lost as it moves through the surface piping and a lot more as it moves down the drill string. Most of the pressure is expended in a jet stream at the drill bit and as it passes through the stages of a downhole motor if being used. At this point the mud pump needs to provide additional pressure to push the mud back along the annulus to the

Gardner Denver PZ8.

surface, while maintaining an operational long term duty cycle. It is also important that the mud pump is sized appropriately to adequately cope with the volumes of drilling fluid required and to maintain adequate annular velocity in the borehole to ensure cuttings remain in suspension in the drilling fluid until the fluid exits the borehole. The capacity of the mud pumps is commonly misunderstood and misrepresented. It is common for people to promote their mud pumps as having a 500gpm (1,892lpm) capacity and a 500 psi pressure rating. While both numbers may be on the spec sheet, promoting the pumps as a 500 gpm pump at 5000 psi is almost certainly incorrect.

For example: A common HDD pump such as the EWECO 446 – a good all-round pump for smaller projects – is often quoted as having an output of 56 5gpm with pressure rating of 5000 psi. While both numbers are true, they are not true together. The spec sheets show that the pump will do 565 gpm at 1200 psi at 440 rpm max with 6-inch diameter liners. Or, if the liners are changed to 3-inch diameter, the pump will output 5000 psi, but even at a max of 440 rpm, the flow output is only 141 gpm. For a long duration longevity on a project, it is good drilling practice to limit the operation to 60 per cent – 70 per cent of the capacity,

particularly pressure capacity. Assuming for small HDD projects where flow is more important than pressure, the minimum pump in the example above with the largest liners which should be considered is a 565 gpm x 65 per cent = 367gpm pump. Applying the same logic to the pressure rating 1200 psi x 65 per cent = 780 psi While there are many contributing factors to pressure such as choke points, valves, drill pipe joint ID, pipe internal roughness, jet nozzle diameter and number to name a few, it would not be uncommon to see 500psi of pressure on a 1000 m jetting hole running 3 x #16 jets at a flow rate of 360 gpm flow rate. If a downhole motor forms part of the bottomhole assembly (BHA) where the formation is rock, it would not be unreasonable to add 150 – 200 psi to the pressure to operate the motor effectively on bottom i.e. 200 psi + 500 psi =700psi. For long term operation, the pump is effectively at maximum capacity. In general terms, additional pumps can be coupled together to increase flow rate but not increase pressure. A longer bore or a higher flow motor would break a single pump in a short time. Double pumps don’t provide additional pressure. To solve the problem, the pump liner diameter must be reduced, which in turn

increases pressure output but decreases flow output. So to drill a longer bore (>1500 m) with large downhole motors (>8-inch), triple or quadruple pumps would be required to provided operational longevity. Or get bigger pumps Maxibor has a fleet four of the largest pumps in the HDD industry: two Gardner Denver PZ9 pumps with 1000 HP engines and two Gardner Denver PZ8 pumps with 750 HP engines. These are 100 per cent duty rated oil well servicing pumps, primarily due to the lowspeed design (130 rpm stroke rate compared to the 440 rpm in the previous example). They have proven project after project to operate at high flow AND high pressure all day every day for months on end. From an HDD perspective, dual PZ 8 / 9 pumps have delivered bores in Australia at lengths of 2,500 m in the civil industry and at lengths of 4,000 m in the gas drainage industry. These pumps allow very long bores to be drilled to solve infrastructure installation challenges or they allow forward motor reaming. This is another technique to solve particular requirements where exit site sensitivities exist, or it is not possible to drill a mud return line. It is these types of pumps that

allow high-performance, cutting-edge HDD bore designs to be achieved. Pumps of this capacity are invaluable, if not a prerequisite, on long bore (+1000 m) and large diameter hole (+800 mm) projects requiring larger maxi-rigs such as the Gallagher 660e, Gallagher 600, American Auger 660 and the Vermeer D330x500, which are a key part of the Maxibor HDD fleet. They are most often required in Australia on river and harbour crossings and long and deep water and sewer projects. Maxibor will be using its Gardner Denver mud pumps on two landmark projects requiring a total of seven bores each averaging over 2.2 km in length. Availability of the pumps has been one of the key factors in the selection of Maxibor as the HDD provider on these projects. A HDD provider like Maxibor, with its sizable fleet of powerful pumps and maxi and other rigs, provides added comfort to project stakeholders that these key plant items will be available to enable the construction schedule to be maintained.

Larger and longer: TRACTO drill facilitates contractor’s biggest installation One of Victoria’s leading HDD contractors, Jelmac, has used a recently acquired TRACTO-TECHNIK GRUNDODRILL 28N to complete the company’s longest installation to date. Equipped with 224 kW of power, a powerful 650 l/min mud system and space to house more drilling rods means the machine is already delivering longer, larger and more efficient installations.

The TRACTO-TECHNIK GRUNDODRILL 28N is the seventh HDD rig in Jelmac’s fleet.

stablished in 2013, Jelmac is a proven trenchless technology leader in Victoria, specialising in horizontal directional drilling (HDD). Based in Melbourne, the company works across all major utility sectors and essential services, as well as local builds and small-scale projects. Over the past few years a significant portion of Jelmac’s resources have been focused on the considerable upgrade to the rail network in suburban Melbourne. The company prides itself on it’s experienced and reliable team, which relishes tackling challenging briefs, no matter how big, small, unique, or complex, working hand in hand with it’s clients to ensure it does everything it can to get the job done, no matter how complex or unique, with full transparency along the way. The GRUNDODRILL 28N is the seventh HDD rig in Jelmac’s fleet, featuring drills of varying sizes and capabilities. The diverse machines give the company the flexibility to

use a ‘horses for courses’ approach to jobs, depending on variables such as the size of the jobsite, geology, and the length and diameter of the installations. One of the key factors which made the machine so attractive to Jelmac was the machine’s immense power, with 100 per cent of the rig’s 224 kW of power directed towards drilling operations. According to TRACO, this aspect of the machine’s design and performance is unique in the up to 300 kN pulling force power class. The extra power also supports an advanced mud system, supplying up to 650 l per minute of bentonite, facilitating increased productivity and faster drilling, as well as opening up the possibility for contractors, like Jelmac, to undertake larger and longer bores. In addition to this power and the effect it has on the functions of the GRUNDODRILL 28N, the drill also features automated and comfort benefitting the end user. Two multi-

function joysticks are used for all functions in bore and drive mode and can be switched between manual, semi-automatic and fullyautomatic modes. In the airconditioned cabin is a panel PC with touchscreen and internet connection, making operations straight forward for the end user. Custom ergonomics have also been considered, with an extra-large and comfortable seat, with air suspension and automatic weight adjustment. Trenchless Australasia spoke to Jelmac Managing Director Brad Boote on the site of a rail project in southeast Melbourne, where the GRUNDODRILL 28N recently completed a 370 m long bore with a diameter of 450 mm in siltstone which he believes to be the biggest installation in the company’s history. “This installation we’re working on here is probably the biggest bore we’ve ever done, lengthwise at the very least,” he says. “Since taking delivery of the machine in August 2021, we’ve seen this machine stack up against similar rigs we’ve used in the past with a few key advantages. “The number one being it’s fluid delivery ability – there’s a lot more litres per minute that we can pump down the borehole which helps us with larger diameter bores, like we’ve just done here,” he says. Mr Boote says another advantage of the GRUNDODRILL 28N is it’s capacity to house almost 300 m of drill rods, meaning on this particular installation his team only had to load a few rods at the very end to get reach the final length of the installation. “A lot of machines only have 180 m of rods onboard, so this would’ve been a big job for a machine like that. The other thing is, at only 3 m, these rods are easier to handle; changing them out is a one person job, whereas with other machines it would’ve required loading one rod at a time using an excavator taking up two people. “A lot of our work is generally under 250

42 TRENCHLESS AUSTRALASIA APRIL 2022

m, so the 28N fits the purpose really well with the diameters that we do, the fluid delivery and the rods – so those three aspects are really important for us. Mr Boote says because a lot of Jelmac’s work is on confined job sites, the design of the machine means it’s suitable for most of the projects they work on. Beyond the technical specs and features of the machine, the clientsupplier relationship is also important to the company. “That is very important to us and is another reason why we decided to work with TRACTO,” says Mr Boote. “Investing in this sort of equipment is always a big decision and a massive commitment. We need to know that we can rely on TRACTO for support, training, sales, servicing and spare parts to ensure the machine is in operation when we need it to be, maintaining the efficiency and the standard of work that our partners have come to expect from Jelmac.” “So far we’re really happy with the decision. I hadn’t had a chance to sit on the machine while it was operating on a job until last week and it was a dream.” For more information visit www.tracto.com/au

S&Z Australia support North East Link early works S&Z Australia has played a significant role in preparations for the North East Link tunnel.

&Z were chosen to reposition several utilities to allow the tunnel to enter and exit without obstruction from pipelines, conduits, and services. These included watermains, major power and gas mains, and services. General manager Jim Pound says the company worked for several different contractors and were required to liaise directly with the various infrastructure companies to ensure their individual requirements and outcomes were met.

Environmental protection matts and other measures used to protect parks and waterways.

“After we successfully delivered 300 mm diameter steel gas main across Lower Plenty Rd and up the Greensborough Highway, we were then asked to install a bank of six large bore HV electrical conduits for another contractor,” says Pound. The gas and power bores were delivered during night works and with restricted hours. This provided an additional challenge to install long strings of conduit and steel pipes within the tight time frames.

Pound says the horizontal direction drilling of steel pipes that don’t have the flexibility of PE pipes is difficult and trying to protect the lining of the gas pipe brought complex measures and procedures. “In the end the Gas Authority were very happy with the outcome and have a much better level of comfort regarding HDD installation of steel gas mains,” he says. The realignment of a watermain and water service followed which were all delivered without any issues. On each section of the project, and for each different contractor or authority, environmental protection measures and procedures were required to protect parks and waterways and manage the drilling waste appropriately. As with every project S&Z deliver, safety was also a major priority, working on major roads with heavy vehicles and during night hours. “The best outcome for us is a project delivered - safely, on time, without incident, to our client’s satisfaction. This was certainly the case on all these projects,” says Pound. S&Z Australia specialise in trenchless pipeline and conduit installations and are experienced at helping deliver large infrastructure projects as well as small to medium projects. Should a project require pipes or conduits to be installed without the interruption caused by open excavation, please contact S&Z Australia.

The Vermeer D130S is a recent addition to the Vermeer range of drills.

A powerful drilling solution for tight, narrow job sites CD Drilling leads the way with power and accessibility.

ne of the major challenges faced by horizontal directional drilling operators is balancing the need for both power and accessibility. This is particularly the case with large-diameter drilling and infrastructure upgrade projects performed in densely populated urban areas. These were the challenges faced by WA based drilling operator CD Drilling, which provides drilling services to major national and local infrastructure operators, mainly for urban renewal projects. The company also operates in regional WA providing drilling services to leading mining companies. With an increased demand for largediameter drilling projects in urban areas, CD Drilling approached Vermeer WA & NT for an equipment solution to bump-up their productivity. What they needed was a powerful drilling solution for tight, narrow job sites. The Vermeer D130S – Combining power with accessibility With a need for both power and accessibility, the Vermeer D130S horizontal directional drill 46 TRENCHLESS AUSTRALASIA APRIL 2022

loomed as the prefect solution for CD Drilling. The Vermeer D130S is a recent addition to the Vermeer range of drills. Designed and built to take on challenging large-diameter drilling projects, without worrying about space restrictions, the Vermeer D130S also keeps surface disruption to a minimum. Being ideal for drilling projects in densely populated residential areas, the Vermeer D130S has quickly been adopted by drilling operators around the world. Now, CD Drilling is the first operator in Australia to take delivery of the revolutionary machine. CD Drilling Operations Manager, Brynn Silke, welcomed the new addition to their fleet. “The D130S has everything that we need in a drill – heaps of power for demanding jobs, plus a small footprint, so it fits into tight residential spaces, and on the back of a semi-trailer when we need to ship out to mine sites. We’re proud to be the first company in Australia to take delivery of the Vermeer D130S, and it certainly puts us ahead of our competitors,” Silke says. The Vermeer D130S is equipped with

578,200 kN (130,000 lb) of thrust and pullback, and maximum rotational torque of 20,337 Nm (15,000 ft-lb), making it capable of penetrating through an array of difficult terrains and ground conditions. Machine manoeuvrability is key to navigating tight, narrow jobsites. With a length of 10.2 metres, and a width of 2.5 metres, the self-contained, compact design of the Vermeer D130S allows for convenient transportation, navigability and minimized setup time. Increasing drilling productivity The Vermeer D130S enables drilling operators to increase their productivity through a number of key product features and options. The drill features an increased rod capacity and an optional crane. “The D130S allows us to drill more as were able to reduce downtime from changing rod baskets. By having a crane onboard, we don’t need a 15-tonne excavator to load rod baskets. This also means we don’t have to worry about extra equipment on cramped job sites,” says Silke.

Case study: Smart Lock restores badly damaged GWM Water network The Smart Lock solution for restoring the pipe was the least disruptive, the best value for money and generated the greatest long-term benefits.

ocated in regional Victoria, local utility GWM Water discovered that one of the network drains had been badly damaged by an external source. The drain had a diameter of 375 mm, and damage was only the top third of the pipe. The repair proposal offered up several different options with varying cost and different degrees of difficulty accompanying each. It was important to work through the different scenarios with the client and look at what was going to deliver the best value for money, cause the least disruption, and generate the greatest long-term outcome.

There was the option of setting up a bypass line over a train line, which instinctively brings with it a complete set of complications that must be worked through, as well as the planning process and time restraints. By using this methodology, there were options to restore the line by either cutting it out and replacing it in its entirety or installing a new top section of host pipe and then patching the area using a bladder in the network. The second option of patching also brought its own challenges around formation of the patch, managing the host pipe repair under inflation, and the team would still have the

bypass line to work through. The suggestion was made to rebuild the line using Smart Lock. This was something the utility had not seen or used before on its network. Smart Locks can be installed to rebuild the line under flow, in this case removing the requirement of bypassing and managing the bypass across a train line. Once GWM Water saw the way that Smart Lock works, the client realised this was the best option on this desperately needed repair. GWM Water was impressed by how the stainless-steel banded together with the silicate impregnated fiberglass to restore the pipe’s shape and build structural

integrity back into the line. Work commenced and the damaged pipe was rebuilt using 5 Smart Locks, each locking into the previous one by managing the pressure used to blow out the packer. Once all the Smart Locks were joined together under live flow, CCTV footage of the drainage system was taken, and the outcome was demonstrated to be successful. The section of the pipe was covered in concrete to alleviate the same mistake happening again. The finished product came up extremely well with little interference to the network and definitely a great saving to the client. How it works The Smart Lock is an innovative solution that is quick and easy, completed in three simple stages: load, lock and leave.

Thinking outside the box Far from the traditional circular and ovoid pipeline relining projects, Rangedale Rehabilitation and Renewals completes relining of two rectangular boxed culverts.

avid Dodemaide is the general manager of Rangedale’s Rehabilitation and Renewals (RRR) division, which specialises in trenchless rehabilitation and renewals. This arm of Rangedale has been operational since February last year, but Dodemaide has a full history in rehabilitation, having worked for 25 years with experts in rehab KA-TE, Inliner, Interflow, Comdain and Insituform. Rangedale Group Managing Director Neil Kermeen brought Dodemaide onboard to get the arm of the business going, and since then, the division has delivered a number of projects for local councils, other tier one/two organisations and water authorities. The most well-equipped drainage and civil services company in Victoria, RRR’s most recent innovative contribution to the industry has been a method for relining boxed culverts. Traditionally, most pipeline relining projects across Australia have been for circular or ovoid cross sections. Boxed culverts have been relined in the past, adopting slip lining methods whereby a liner is made-to-measure in the factory smaller than the existing culvert. The liner is then pushed or pulled through the existing structure, leaving a gap between new and old that is filled with grout. This smaller cross-section usually results in diminished hydraulic capacities after relining. Costs and construction times also increase due to the large

52 TRENCHLESS AUSTRALASIA APRIL 2022

volumes of grout required to fill the gap between old and new. Case study In February of this year, Rangedale Rehabilitation and Renewals was awarded a project by BMD Constructions, contracted by Major Road Projects Victoria. The contract was to design and construct the relining of two boxed culverts. RRR has previously been involved in joint projects with BMD, and had developed a strong working relationship with BMD. As a result the company was approached to carry out the relining of two boxed culverts. At 450 mm wide and 300 mm high, the two boxed culverts were requiring urgent repair works. The solution needed to be cost effective, meet the tight project timelines, ensured a 100year design life, and to not alter the hydraulic capacity of the newly installed drain. Rangedale offered a unique solution to BMD and the asset owner. A German-manufactured Saertex circular UV-cured, cured-in-place pipe (CIPP) liner is inflated to the highest pressure and formed to the rectangular shape of the culvert. The Saertex CIPP liner is designed in accordance with 100-year long-term properties and is deemed the best in its class with an extremely high stiffness modulus. The liner assumes the shape of the culvert.

Vertiliner project.

Small gaps left in the corners are filled with a highly flowable grout to further support the liner. The grout has no bearing on the structural integrity of the liner - it only adds additional support to the liner in the corners. Furthermore, the GRP liner surface is almost frictionless, providing the client with an increased hydraulic capacity after relining. The result exceeded expectations, and the company said it plans to use the technology on future projects.

Vertiliner RRR delivered another complex and critical project in January this year for Programmed Facility Management (PFM) and principal water authority Greater Western Water (GWW). RRR was contracted to reline 14 sewer access chambers, each varying in condition, with hindered access to the structures where GWW customers were depositing trade waste into the sewer system. There were three major challenges that faced the RRR team on the project. The first was that the area was a designated ‘no-go zone’. Working downstream of the industrial waste discharge points, the team faced high flows of hazardous effluent that required a diversion of sewer inflow and thorough risk management.

Boxed culvert after relining.

The second challenge was that each access chamber manhole was severely degraded. Decades of highly corrosive effluent passing through the system had corroded the concrete, causing significant damage. Thirdly, the high-risk profile of the project meant PFM and GWW needed a contractor who could minimise entry to the fully deteriorated structure. Traditionally, access chamber rehabilitation solutions rely on the integrity of the existing structure in order for a protective coating to be applied and bond to the remaining surface of the access chamber. Other systems require extensive operator entry to install the liner such as slip lining and other hand applied structural liners. Rangedale offered a structural lining system that

did not rely on the integrity of the manhole and was installed with a method that minimised operator entry. Rangedale installed the Vertiliner system which is a UV cured-in-place pipe (CIPP) liner, manufactured to the exact fit of each access chamber. The liner was installed from surface level without entering the access chamber, then inflated with air pressure and rapidly cured using ultraviolet (UV) light mounted inside the inflated liner. The end product was a structural glass reinforced plastic (GRP) pipe liner, installed as a structural liner independent of the original access chamber. Using unique UV cured CIPP technology, Rangedale installed 14 structural liners within a three-week period from surface level. The RRR Team are the only Australian land-based contractor to have undergone the extensive training and R&D requirements needed in order to install these liners. This state-of-the art technology is new to the Australian rehabilitation and renewals sector and represents industry leading best practice.

Prime Minister Scott Morrison, Minister for Employment Stuart Robert and Federal Member of Chisholm Gladys Liu at KOR.

Coalition visits KOR facility KOR Equipment Solutions had a visit from Prime Minister Scott Morrison, Minister for Employment Stuart Robert and Federal Member of Chisholm Gladys Liu at KOR in Mulgrave, Victoria, in February.

he visit was to promote the Coalition’s focus on job creation and skills training ahead of the upcoming Federal election. KOR Managing Director Stephen Pewtress made opening remarks and introduced the special guests before the Prime Minister’s address onsite. During the announcement, Morrison promoted the Coalitions’ plan to increase investment, job creation and wage growth to contribute to better standards of living across Australia. “That is the economic plan that is driving Australia’s unemployment rate to below four per cent, the plan that has ensured we’ve been able to maintain our AAA credit rating, one of only nine countries in the world to do so, particularly during the course of this pandemic,” says Morrison. “And the plan that is taking us forward to see more jobs and more investment backed up by investment allowances and research and development tax concessions, that is enabling businesses to find new solutions.”

In March the Morrison Government announced a new $1.6 billion economic accelerator to develop businesses and build Australia’s economic resilience. The KOR team thanked the Prime Minister and the accompanying dignitaries for their visit, stating that job trainer initiatives under the Coalition are helping

the company to grow across the regions KOR operate in Australia. “Thank you, Prime Minister, Minister Robert and Member for Chisholm Ms Liu, for taking the time to see first-hand how KOR has continued to expand its operations under the challenges of a pandemic,” Pewtress says.

L&D purchases new high-power vac truck

Chris Dean selected a CAP VAC INDUSTRIAL 3200 because it was the best in the market in terms of the power of the vacuum and quality of the truck.

L&D Micro Tunnelling has bought a CAP VAC INDUSTRIAL 3200 to increase its productivity, versatility, and efficiency.

&D Micro Tunnelling offers a range of services including free boring, sleeve boring, pipe jacking, hydro excavation, and pilot auger boring, as well as specialist machine hire. Co-owners Luke Lewis and Chris Dean specialise in high-accuracy laser guided boring; the company has three tunnel boring machines (TBMs) operating throughout Victoria with drill heads ranging from DN350 to 600. As the newest addition to its fleet, L&D Micro Tunnelling acquired a CAP VAC INDUSTRIAL 3200 by KOR in December 2021. Mr Dean says the company selected this machine because it was the best in the market in terms of the power of the vacuum and quality of the truck. It was the final piece of the puzzle for the company. Finally completing their third laser guided boring machine, LD3. L&D is no stranger to the CAP VAC INDUSTRIAL 3200. The company previously used to hire the units, but due to the rate at which they were using it on jobsites, it made more economical sense to buy a truck of its own. The CAP VAC INDUSTRIAL offers both a wet and dry function. The capability of the unit to complete dry vacuum recovery applications increases the versatility and productivity of

the unit. Meaning the company can tunnel through clays adding water as a traditional method, or when they encounter dryer ground condition such as mudstone and siltstone, they can drill through these materials without adding water and therefor recover more spoil per tank. The high power of the vacuum is capable of either method what ever the project requires. Since acquiring the new machine, Mr Dean says the truck has been out in the field almost every day. “It’s really the best product in its class. It’s the most powerful, most versatile, and we use it on nearly every job we complete, we only wish we purchased it sooner.” he says. “Primarily used with our tunnelling machine It also allows us to give clients the option to do hydro excavation onsite as well.” The CAP VAC INDUSTRIAL by KOR is designed for Australia with a simple and ergonomic design tailored to our conditions. With 270-degree boom rotation and an 8-inch vacuum hose, this wet/dry vacuum recovery unit is ideal for businesses looking to expand their operational capability to complete more dry excavation work. With a 5100 kg payload, the high-powered vacuum drives higher productivity and

efficiency while reducing operating costs with lower fuel burn than traditional equivalents. Mr Dean and Mr Lewis understand the need for precision, pride themselves on building client relationships and thrive to always deliver an economic, reliable service to companies across Victoria. That’s why they invest in only the best machines to deliver the greatest outcomes for their customers.

AI in the water sector: Safer, faster, better Once considered a threat to people’s jobs, automation is enabling many in the water sector to leave mundane tasks behind and focus on high value work.

ngineering graduates and other specialists are often employed to sit in front of video screens for weeks on end to watch footage from drone-mounted cameras being driven through pipes. The purpose? To assess where pipe maintenance needs to be carried out. But no engineer wants to spend their days in front of a screen watching videos of the inside of a pipe. Fortunately, technology offers a smart solution for this. What a difference data makes Technology fuelled by artificial intelligence (AI) is driving change in the water sector. Once considered a threat to people’s jobs, such technology is now helping people do more of what they want to do, while meeting increasingly high expectations. For example, councils and water authorities have extensive kilometres of underground pipelines for wastewater, stormwater and water. “Many of these pipes are approaching the end of their life and they need to be renewed,” says John Phillips, Business Development Manager at Interflow, a leader in pipeline infrastructure. “Digging them up to replace them all would be extremely expensive and would disrupt communities.” How, then, does a water manager assess

where the work needs to be done? Previously it has been undertaken by sending a camera through the pipes and relying on an operator to conduct an accurate analysis. “By the time they engage a contractor to do the upgrade work, often the footage is very old,” Phillips says. “Things could be completely different by the time we go to do the job.” That’s where a neat, AI-based solution comes to the fore. The future of water management is here A faster, more accurate solution is now being An engineer watches CCTV footage to identify and categorise defects.

utilised by leading councils and authorities. It’s one that removes repetitive and low-value work and liberates engineers and others to do the higher-value tasks that keep communities’ infrastructure running smoothly. “The analysis of the condition of the pipes can all be done by machine,” says John Weaver, Contracts Manager at Interflow. Instead of camera footage being analysed by humans, it is analysed by an AI engine that has been trained on tens of thousands of hours of similar footage. “It categorises every individual issue found and provides an immediate, real-time report of the entire pipe network,” Weaver says. “A recommended capital works program, complete with anticipated costs, comes with the analysis. This means the council or water authority can work that program into their budget over the next four or five years.” The transformative effect of AI is making condition assessment reports and asset maps faster, more objective and more consistent. Wherever such technology is introduced it removes often mundane and repetitive work and frees engineers and other staff to perform higher-value tasks. And in the current environment in which the war for talent has become very real, anything that can be done to make work more engaging and relevant is welcome.
