Editor’s letter Molly Hancock

elcome to the last edition of Trenchless Australasia for 2023. What an achievement it is for many to make it through these last 12 months. From writing about the industey completing major projects to attending my second No-Dig Down Under, this year has been huge to say the least. However, the trenchless sector continues to come out stronger and more versatile every year, by enhancing its technology and working together to create better solutions for the challenges faced. In this edition we celebrate and welcome Bothar’s Shane Kimpton, Rangedale’s Adam Kermeen and TDG Environmental’s Shane Curren. To read more about their roles and ambitions, check out the People on the Move feature on page 58. This edition also highlights the safety and training work being done in the industry. While trenchless technology and methodologies are still considered a niche segment of the construction industry, significant work is being done by stakeholders to ensure the benefits of no-dig methods are becoming mainstream, and importantly completed in a safe and sustainable way. In addition to this theme, other unique features in the next edition

include Horizontal Directional Drilling, Rehabilitation and Repair, Microtunnelling, Waste Management, CCTV and Inspection, and Relining. Alongside these important topics of the industry, we take a step back and look at the top stories of 2023. Here we celebrate contract wins, project progressions and the people who make up the trenchless industry. We also put a spotlight on The Australasian Society for Trenchless Technology’s (ASTT) calling for applications to the Young Trenchless Professionals (YTP) Committee - a new venture for young members of the trenchless industry. Led by ASTT Victorian Councillor Ashley Hamer, the committee will work collectively with the ASTT to generate new and innovative ideas to setup for a successful future. The team from Trenchless Australasia thank you for your support during 2023 and wish everyone a happy and safe Christmas and New Year. We look forward to joining you again in 2024. Happy reading!

hat a year it has been for the ASTT. From No-Dig Down Under back again in 2023 to successfully securing the ISTT International No-Dig event in Auckland in 2026, this year has been eventful. This would have not been possible without the support of the trenchless industry, our ASTT members, the ISTT and Prime Creative Media. Thank you to our sponsors and exhibitors for continuing to believe in the vision of No-Dig Down Under and supporting the event. Without you this event would not be what it is today. No-Dig Down Under 2023 returned for a second year in a row, hosted at the Brisbane Convention & Exhibition Centre, proving again to be the largest trenchless technology trade show in the Southern Hemisphere. The conference theme this year was ‘Better Outcomes Through Trenchless’ and through this theme we stimulated the conversation and papers, and the panel discussions on improving the service industry with better design, better method selection, and better delivery to conclude improved overall trenchless solutions. I for one, find each No-Dig Down Under event more inspiring than the last, and this year once again did that. Looking to the future, the ASTT has

been successful in its bid to host the 2026 International No-Dig Conference and Exhibition in Auckland, New Zealand. This is off the back of Secretary Trevor Gosatti and Prime Creative Media’s Simon Coburn presenting a bid at the recent ISTT International Council Meeting at its International No-Dig Event in Mexico. This will be a great opportunity for the industry in New Zealand to showcase its capabilities and celebrate the trenchless projects and technologies in the country. As you will see in the pages of this edition, Victorian ASTT Councillor Ashley Hamer has put a call out to young people in the trenchless industry to join our newly formed Young Trenchless Professionals Committee. Joining the committee will bring benefits such as professional development, networking opportunities, knowledge sharing, mentoring and coaching opportunities. While we say goodbye to 2023, myself and the ASTT wish everyone a happy and safe Christmas and New Year. We look forward to connecting with the industry again in 2024 and seeing everyone in person at the 2025 No-Dig Down Under event in Melbourne, Victoria. Ben Crosby ASTT President

Prior to the No-Dig Conference, the ISTT International Council (made up of representatives of the 28 affiliated societies) met and discussed the business of the ISTT.

ASTT, together with its media partner, Prime Creative Media, presented a bid to hold the 2026 event in Auckland, New Zealand. The event is to be hosted at the New Zealand International Convention Centre, which is currently under construction. The ISTT International Council unanimously voted in favour of the proposal. The New Zealand International Convention Centre is due for completion mid-2024 and will be a world class facility. It will be one of only three carbon neutral convention centres in the world, and a great location to highlight technologies such as trenchless technology. The ASTT strongly believes that hosting the 2026 ISTT International No-Dig Conference and Exhibition in Auckland will be a fantastic opportunity to promote and showcase the vibrant trenchless technology community in the Australasian region, particularly in New Zealand, to the rest of the world.

ASTT successfully bids for 2026 ISTT NoDig Conference The ASTT is extremely happy to advise that its bid to host the 2026 International NoDig Conference and Exhibition in Auckland, New Zealand was successful. At the recent ISTT International Council Meeting at the Mexico City Conference, the

YOUNG TRENCHLESS PROFESSIONALS

The next generation of trenchless The Australasian Society for Trenchless Technology (ASTT) is calling for applications to the Young Trenchless Professionals (YTP) Committee, a new venture for young members of the trenchless industry.

Ash Hamer, pictured far right, leads the Major Projects Team at Yarra Valley Water.

eveloped for members of the trenchless community aged 35 years or younger, the YTP Committee will focus on assisting the ASTT achieve its mission and strategic objectives. “The ASTT understands the importance young trenchless professionals play in leading trenchless technology into the future,” ASTT Victorian Councillor Ash Hamer said. “We want to access new ideas and innovation through the next generation.” Hamer, who is leading the charge in calling for applications, first joined the industry 15 years ago through his graduate role at Baulderstone on Melbourne Water’s Water Resources Alliance. “I still remember my first day walking into the Kodak Building on Victoria Parade not knowing what to expect and I’ve been in the water industry ever since,” he said. Currently, Hamer leads the Major Projects Team at Yarra Valley Water. “I’ve been lucky to work on some amazing trenchless projects like the Lockerbie and Epping Main Sewers that have all demonstrated how critical trenchless technology is to the water industry,” he said. “The water industry has a knack of making you love it, so I’m well invested in it. And it’s an exciting time for trenchless technology given the growth in the industry”. Hamer said the committee will work collectively with the ASTT to generate new and innovative ideas to setup for a successful future. “The committee will work on strategies and initiatives to advocate and support the leadership of trenchless technology,” he said. 12 TRENCHLESS AUSTRALASIA DECEMBER 2023

“This could look like organising networking events or trenchless forums. “Ultimately it will be up to the committee with where they want to focus on, which is an exciting opportunity to a part of.” A minimum of five members will be selected for the YTP committee, with all members required to be members of the ASTT, either

individually or under a company membership. As Hamer explained, the committee is seeking a broad range of diversity of thought, gender, background, and experience. “You don’t have to fit a certain mould, we’re after diversity of thought and want you to bring your true self to the committee to make it great,” he said. The expectation is that the committee will meet every two months virtually at a minimum, and in person once a year with travel funded by the ASTT. In return, joining the committee will bring a wealth of benefits such as professional development, networking opportunities, knowledge sharing, mentoring and coaching opportunities. For anyone wanting to join, Hamer offered some words of encouragement. “Step out of your comfort zone and challenge yourself,” Hamer said. “From my own experience, the opportunities that I was most nervous about were the most rewarding.” Applications for the YTP committee close on 15 December 2023. To submit an application, send a current CV and cover letter to Ash Hamer at ash.hamer@yvw.com.au

NEWS FEATURE IN BRIEF

Rob Carr locks in Alkimos project contract Microtunnelling contractor Rob Carr is continuing to make waves in the trenchless industry with the recent contract award for the Alkimos Main Sewer Section 1 construction. The Alkimos Main Sewer Section 1 is a major capital works project for DevelopmentWA. This will tie in with a 68m section of sewer beneath the rail corridor near Alkimos Station, completed as part of the Yanchep Rail Extension by METRONET. The contract win for Rob Carr follows a competitive tender, which involved ongoing collaboration with several stakeholders for the major Alkimos Central Development. This was a necessary and valuable part of the process to ensure a “best for project” outcome for all parties involved. Rob Carr will self-perform the construction of 830m of DN1500 sewer and three access chambers. The sewer will be constructed by two sections of micro tunnelling (157m and 306m), with the remainder constructed by open excavation. The company has advised that over the next few months, other work on the project will include the construction of a 10m diameter in-situ concrete launch shaft some 9m deep, and a 12m deep receive shaft constructed using post and rail techniques.

Eight benefits of high-speed cleaning with Picote Solutions equipment

With servicing, stock and official Picote training available locally through Pipe Core, there are numerous reasons to grow businesses with the addition of Picote Solutions equipment.

The benefits of high-speed cleaning with Picote Solutions’ range of equipment have a global history that is now being seen in Australia and New Zealand. Through its high-speed Millers and tools, Picote Solutions has developed equipment that is both safe and effective for cleaning without the risks of traditional mechanical cleaning equipment. Thames Water contacted Picote Solutions with safety concerns and issues regarding the removal of concrete from their sewer network that was currently being undertaken with a combination of Ultra High Pressure and High-Pressure Water Jetting. The project involved cleaning a 27m DN 150 clay pipe located in a narrow access lane leading to a construction site. The pipe was full of concrete of various depths ranging from 40 per cent to 100 per cent. Once Picote Solutions was engaged, there was a major reduction in cleaning and labour time with the works being completed in three days, with the rate of cutting and removal varying depending on the consistency, hardness, and level of cementitious material. Significant environmental savings were also made by the team using the equipment, who managed to complete the works in three days versus the 44 days that the existing equipment would take. This method also demonstrated much lower water usage than other pipe cleaning methods.

Discover KRE Engineering’s extensive range of SAVA pipe products The company has just received a bumper shipment of SAVA pneumatic pipe plugs and rehabilitation packers. “SAVA pneumatic pipeline products are best known for their quality & reliability,” KRE Engineering Services sales manager Mick Butler said. The pipe plugs and packers are used for numerous interventions.

UNDER VICTORIA

Trenchless technology on display across Victoria From the regional cities of Bendigo and Ballarat to the metropolitan hub of Melbourne, trenchless technology continues to shine across Victoria.

n December 2022, Central Highlands Water’s Ballarat Sewer Build commenced stage two with microtunnelling beneath Humffray Street South. Similarly in Bendigo, Coliban Water used a $1.5 million laser-guided tunnel boring system to replace the East Bendigo sewer trunk main. In July 2023, South East Water announced a $1.5 billion investment in infrastructure upgrades across Melbourne’s south-east. Tunnelling work also began on Melbourne’s newest sewer pipeline. Ballarat sewer build uses microtunnelling For stage two of the Ballarat Sewer Build, a microtunnelling machine will bore a 700m, 1200mm diameter tunnel beneath Humffray Street South. Minor repairs and sewer pipe relining for the existing pipes will also occur during tunnelling operations. The project represents a $25 million investment from utility company Central Highlands Water and will bolster the city’s two largest sewer lines – the Ballarat East and Ballarat South – which were constructed almost 100 years ago. Since the original pipes were laid, Ballarat’s population has grown by more than five times to 117,000 people. Once all stages are completed, two large interconnecting sewer lines will run beneath the streets of the city, approximately 6km in length.

Coliban to tunnel new sewer in Bendigo The East Bendigo sewer trunk main is set to improve Bendigo’s growing population. Coliban Water Manager of Infrastructure Corey Bourne likened the tunnelling technology to the massive tunnel boring machines digging the Melbourne Metro Tunnel, but on a much smaller scale. “The technology means we can reduce the need for excavation, limit disruption to nearby residents, and avoid damage to trees and habitat,” he said. “It allows us to constantly monitor and manoeuvre the machine to ensure accuracy.” The company is working with Bohrtec to bore a microtunnell that will house the new 507m sewer trunk main. “The new sewer main will cater for Bendigo’s growing population by improving 16 TRENCHLESS AUSTRALASIA DECEMBER 2023

Trenchless technology continues to showcase its benefits in infrastructure projects across Victoria.

the capacity of the network to carry sewage from the growing suburbs of Strathfieldsaye, Junortoun, parts of Strathdale and East Bendigo to the Bendigo Water Reclamation Plant,” Bourne said. South East Water announces monumental infrastructure upgrades The “shovel ready projects” impacted by this announcement are the Dingley Recycled Water Scheme, the Mount Martha Water Recycling Plant clarifier upgrade and the Caulfield West branch sewer renewal among others. “We are embarking on a transformative journey with our new industry partners Abergeldie Complex Infrastructure, BMD Group & KBR, Inc(ABK), and Beca Hunter H2O, Fulton Hogan & Interflow (BFHI),” the South East Water team said. “This collaboration, facilitated by our new integrated capital works planning and delivery model, sets the stage for major network upgrades over the next decade.” This enthusiasm was shared by South East Water Managing Director Lara Olsen. “We’re thrilled to welcome ABK and BFHI to the South East Water team and look forward to working together to ensure quality and reliable water, sewerage and recycled water services for 1.8 million people, now and into the future,” she said.

Melbourne’s newest sewer under construction Almost 65 years after the original sewer was built, and responsible for the transfer of 30 per cent of Melbourne’s wastewater, the new 670m Hobsons Bay main sewer stretches from Westgate Park, Port Melbourne to Scienceworks in Spotswood, under the Yarra River. “The Hobsons Bay main sewer project forms part of a broader Melbourne Water capital infrastructure program that will enhance the reliability of our sewerage network and services for the benefit of Melburnians today and for generations to come,” Melbourne Water Managing Director Nerina Di Lorenzo said. “We’re looking towards the future and anticipating the evolving needs of a growing Melbourne – which is projected to nearly double in population by 2050. “This project ensures our infrastructure is keeping up with future demand.” The $206 million Melbourne Water-funded critical sewage infrastructure project allows sewage to continue to flow to its Western Treatment Plant while the existing sewer – which is reaching the end of its service life – is upgraded. A joint initiative delivered by the Victorian Government, Melbourne Water, John Holland and Museums Victoria; the project is due for completion in mid-2024.

EDUCATION & TRAINING

Looking at ASTT’s policy and promotion of trenchless technology operator qualifications The ASTT Secretary Trevor Gosatti has taken a deep dive into how the society promotes the use of trenchless technology ahead of traditional excavation and replacement construction methods.

renchless technology includes benefits in the social, economic, and environmental factors that apply to a proposed worksite. The ASTT strongly believes that all operators performing trenchless technology works on a civil infrastructure worksite, should as a minimum, be of a “tradesperson” level standard, regardless of the types of work. A tradesperson level qualification is the equivalent of an Australian Qualifications Framework (AQF) Level Three (III) qualification that is recognised Australia wide. The Australian Qualifications Framework (AQF) is the national policy for qualifications in the Australian education and training system. However, the qualifications system is slightly different for New Zealand in comparison to Australia. In Australia, the ASTT has advocated for and obtained industry qualifications and competency units for the trenchless industry. For over 20 years now the society has supported the qualifications and competencies on various industry bodies and provided resources towards the training and assessments of trenchless competencies for Registered Training Organisations (RTOs) to deliver them. There are three Certificate Three (III) qualifications that trenchless technology operators can obtain to be regarded as a tradesperson level recognised operator: • Certificate III in Trenchless Technology (RII31619) (Preferred by ASTT) • Certificate III in Civil Construction (RII30920) (with inclusion of the relevant RIICTT [trenchless] competencies) • Certificate III in Drilling Operations (RII31820) (with inclusion of the relevant RIICTT [trenchless] competencies and Locating services competencies) Details of the qualifications are provided on the www.training.gov.au site, which is the Australian Government qualifications site. Qualifications are typically a package of competencies (units) relating to various skills to form a recognised qualification. Competencies can also be attained in a manner to recognise particular skill sets, which can be part of a qualification. 18 TRENCHLESS AUSTRALASIA DECEMBER 2023

RIICTT competencies: RIICTT301E

Conduct fluid assisted directional boring

RIICTT302E

Conduct impact moling, ramming and augering operations

RIICTT310E

Renovate large diameter pipes and chambers

The qualifications are flexible to suit the type of trenchless technology occupation that is sought. The type of occupation sought relates to the specialist trenchless technology competencies that are contained within the qualifications. At least one of these competencies (RIICTT) must be completed to attain a trenchless technology recognition. There are currently 10 specialist trainees that would select the appropriate trenchless competency unit to be attained relating to the occupation they seek to obtain qualifications for. The specialist competencies cover the various occupations include horizontal directional drillers, micro tunnellers, pipeline and chamber renovators, in-situ pipe replacement and pipe relining. In addition, associated competencies such as vacuum excavation, track directional boring operations and installing trench shoring can be attained as part of a flexible skills-based qualification. The attainment of recognised qualifications should be done through a Registered Training Organisation (RTO) that is registered for the national VET (Vocational Education & Training) Framework, and scoped to deliver training and assessment for the relevant qualification. Trainees and employers should engage an RTO to deliver and assess the learned skills for each of the competencies acquired, that package up to form the eventual qualification. The reality is that most of the skills required for trenchless technology

skills are typically learned in an on-site environment, and training and assessment requirements would be framed accordingly for that. A small amount of training would be done in a classroom. Various government subsidies are offered towards the completion of a qualification. New trainees would have a program outlined (in consultation with the employer) by the RTO to obtain the qualification. Existing operators who have already acquired skills in their on-site learning during their employment can be assessed and seek recognition of prior learning (RPL) for the various skills and competencies they may have already. The RTO can then map out the further skills/competencies required to attain the relevant trenchless qualification. The ASTT believes that it is important that trenchless technology skills be recognised and we encourage all employers and operators to seek to attain industry recognised qualifications. We acknowledge that there are many operators in our industry that have significant skills but have not been formally recognised for them in the form of competency units or qualifications. We believe there are significant benefits for the individual operator, their employer, and the industry in general if skills are formally recognised and we encourage this to occur. The ASTT acknowledges the impediments that the industry has experienced that

has not encouraged the attainment of formal qualifications: • Cost – there is a cost to the employer in time spent to train and assess trainees for qualifications. Government provides various subsidies and grants to off-set some of this, but there is no doubt a cost to the employer. This cost however should be seen as an investment not a cost to the organization. Can you afford not to invest in your staff and improve their skills? • Lack of RTOs – This is the chicken and the egg question? If the industry does not have the demand to train and assess its trainees and operators, the RTO’s will not scope up to provide their services. If as an industry we demand and require training and assessment, many RTOs will scope up and provide the service. The ASTT has a number of RTOs as members and they would be able to assist. • Equal playing field – As a trenchless technology contractor you may have to compete against other companies that may not be investing in staff and training. They get away with it because the Asset Owners that contract the work via the tender box, or quotation, do not demand a minimum level of training or qualification. If it is demanded at the tender stage by all asset owners, then the cost will be built in to the works and be equal to all. The ASTT supports the following policy: ASTT Policy The ASTT supports the promotion of Certificate III trenchless technology qualifications and recommends that as a minimum asset owners should require that for each trenchless technology crew, at least one person within the crew has obtained one of these qualifications. In the initial instance a staged approach

the trenchless technology industry is a genuine one with many benefits. They learn on the job skills along the way, get paid whilst working, and obtain qualifications. It is an alternative pathway to doing tertiary education straight from school with little or no practical experience. I also want to highlight that there are other pathway options for our industry through the VET sector. The ASTT strongly supports the training and education of the trenchless technology industry in a number of ways: • We offer and deliver various one day educational courses (licensed via NASTT and amended to suit ASTT audience) prior to the No-Dig Down Under event. We will be looking to expanding these opportunities in the future. • We advocate industry-led promotion of qualifications to government, asset owners and industry stakeholders and promote our policy. • We support and have been involved in the creation and maintenance of the trenchless technology competencies and qualifications as part of the AQF training packages. We were an active member of the Resources and Civil Infrastructure Industry body that managed the training packages, and we will look to be part of the new BuildSkills Australia entity that will oversee the training packages in the future. • We have provided resources towards the training and assessments of trenchless competencies assist RTOs to train and assess trenchless industry trainees. The ASTT is happy to assist any member that needs assistance regarding training requirements.

(over a period of time i.e. up to two years) may be suitable to accommodate the industry. The promotion of having qualified persons on all jobsites is a policy that will improve the safety and quality of infrastructure works for asset owners. The ASTT believes that asset owners that are not asking, as a minimum requirement, that all operators be qualified to a Level III (tradesperson) level qualification (or equivalent), may be deemed negligent in their responsibilities should an incident occur. The trenchless technology industry benefits greatly as more skilled operators attain nationally recognised qualifications. The following AQF qualification types are recognised in the VET sector: • Certificate I • Certificate II • Certificate III - tradesperson level • Certificate IV - supervisor level • Diploma • Advanced Diploma • Graduate Certificate • Graduate Diploma - engineer level This pathway to become an engineer through

Become a hydro excavation pro Asset Training’s Registered Training Organisation Manager Chris McCarthy sat down with Trenchless Australasia to walk through the details of its ‘Operate a hydro excavation system’ training course. Any hydro excavation system that utilises a Class B high pressure water pump must have training completed through a dedicated RTO.

irst developed in 2006 under parent company Aqua Assets, Asset Training is a safety-based Registered Training Organisation that provides training within the industrial services and wastewater management industries. “We have grown exponentially now to the point where we have three training facilities in New South Wales, plus have the ability to deliver onsite training nationally and in New Zealand,” McCarthy said. Under the Australian Standard (AS4233), any hydro excavation system that utilises a Class B high pressure water pump must have training completed through a dedicated RTO. Asset Training addresses this need with its new ‘Operate a hydro excavation system’ course. “The course is aimed towards people who perform either hydro excavation or nondestructive digging (NDD) for all manner of functions including locating and exposing underground assets,” McCarthy said. “Traditionally, it was an excavator, a mechanical process or a person with a shovel that would perform these tasks. “In recent years hydro excavation or nondestructive digging has become the go-to process for locating underground assets. Hydro excavation is less invasive, more efficient and reduces the risk of damage to the underground assets.” Throughout the course, students will learn 20 TRENCHLESS AUSTRALASIA DECEMBER 2023

Success shaped by people For almost a century, Interflow has encouraged its team members to learn new skills. The HJ Weaver Development Program now enables people to develop new competences for their future careers within the company.

fter his first six months with Interflow as an intern, promising engineer Matt Cremona was offered a place in a program that would introduce him to all parts of the business. “It was all about experience and opportunity,” Cremona, now Interflow Delivery Manager, said. “I was given the opportunity to rotate around different divisions, for six months to a year each, within the organisation. “I spent some time with operations, asset creation, repairs and maintenance, product development and tendering.” He’s adamant: the strong connections he built across the business has helped his career ever since. “Having those relationships meant that when I was given opportunities in other divisions, I could rely on those relationships to help me in my new roles,” he said.

That was 13 years ago. Interflow’s approach was built on founder Harold ‘Bill’ Weaver’s passion for developing his people to be their best and formalised more recently as the H J Weaver Development Program. “The program is all about supporting and developing people over the years by creating a business environment that encourages, enables and supports learning,” Interflow People and Capability Business Partner Fiona Warnock said. “It’s looking not only at the entry level. It’s also about our existing team members.” According to Warnock, the program is more like an education assistance policy than a pure graduate program, as it is made up of two streams that promote learning and development at every level. One is for the business’s interns, undergraduates, and graduates. The other focuses on existing team members who want to

develop or change their careers. Chosen education programs are eligible for funding, including fees, textbooks, and union fees. For the graduate, that can represent an investment of over $30,000 in their professional education. “Many businesses offer rotations into various departments or programs,” Warnock said. “But this financial support for education programs, on top of coaching, rotations, mentoring and other development opportunities, are a real value add for our people.” According to her, it’s vital that businesses planning for growth are also putting internal talent development structures in place to ensure the future growth can be supported. “When people realise, they are a vital part of that growth story, when they realise they’re valued and are being nurtured and developed, that’s what makes them want to stay with us.”

The HJ Weaver Development Program made a measurable difference in Matt Cremona’s life.

How the HJ Weaver Development Program works The most important steps in the evolution of the HJ Weaver Development Program have been the analysis of what types and levels of talent the business will require over the next five to eight years, and the creation of a talent map that informs the business of what it has in place right now. There is a framework built around how the program works, ensuring there are clear channels in which people can request, report on and record progress within specific educational programs. The next step comes from mid-year and annual performance reviews, during which a development plan is discussed. Development opportunities that are identified during those reviews are then run by the individual’s line manager and the Executive General Manager. Why development is worth the investment There is great longevity at Interflow in terms of average employment periods. Part of this is explained by the fact that the business demonstrably values its people, putting its money where its mouth is. “It really does create a personal touch, a sense of investment in the individual,” Warnock said. The program made a measurable difference

It’s crucial that businesses planning for growth are also putting internal talent development structures in place to ensure the future growth can be supported.

in Cremona’s life and career. “I was given an opportunity to set myself up in terms of career and development,” he said. A lot of other graduates Cremona had gone to university with had a difficult time finding careers or job opportunities. However, thanks to being developed through the HJ Weaver Development Program, he had security. “As I graduated, I was also being exposed to different avenues, different divisions and different relationships,” he said.

“It has helped throughout my entire career so far. Every time I have stepped up, like when I became a Project Manager, I had a good understanding of the company background.” Cremona is now using what he’s learned to support and develop his own team at Interflow. “I have the confidence now to know what I’m saying is right and to back my own decisions,” he said.

The next level of CIPP Sewer Equipment Company Australia (SECA) is set to become a distributer of Bluelight® LED cured-in-place pipe lining, an innovative tool for pipeline rehabilitation. Founded in 1967, SECA is a leading supplier of equipment for the cleaning, testing, inspection and rehabilitation of pipes, sewers and drains. The company has been providing innovative technologies for sewer asset management for decades, with customers ranging from residential plumbers to councils, water authorities and contractors. With its expert knowledge, service, and support, SECA offers a one-stop shop for the trenchless industry with the equipment it needs for repair and rehabilitation projects, with the added confidence that comes from using one of the country’s most experienced suppliers.

hen it comes to pipeline rehabilitation, cured-in-place pipe lining (CIPP) can bring many costeffective benefits for operators. Light-curing CIPP systems are an advanced choice as they use light to cure the resin of liners, lowering costs, time, and resource requirements. While there are many options on the market, US manufacturer HammerHead® Trenchless’ Bluelight LED CIPP lining system brings an innovative approach to lateral rehabilitation by using the blue light wavelength instead of ultraviolet light. Used for non-pressure pipelines up to 150mm in diameter, the lining system rehabilitates pipelines by installing a resin saturated fabric tube which is inverted into an existing pipeline and expanded against the interior of the pipe during LED light cure. The system specifically uses the blue light wavelength to provide a focused range of visible light, which in turn, allows for positive impacts on the quality and speed of the curing process. This also gives installers a longer working time between liner wet-out and curing as the liner only goes off when it is exposed to the blue light. Once installed, the automated curing system pulls the LED light head through the liner and cures the resin almost instantly and is five times faster than other methods. The Bluelight LED CIPP system is used for a breadth of applications, adding versatility to its list of benefits. It can be used for storm and sanitary sewers, drainage, vents, and other piping systems, and is also resistant to sewage and acid in drains.

The system can also navigate 45 and 90-degree bends, with single diameter transitions also available. Innovative features The Bluelight LED CIPP system has a wealth of features to assist operators with productivity. Interchangeable reels: With its convenient transportation, these reels allow installers to keep operating if a reel requires servicing. Portability: The lightweight design of the system is easily transportable and makes it easier to work around smaller job sites.

Close up shot of the light head.

Automated pullback: The onboard computer controls the pullback speed on job parameters to fully cure the liner, reducing potential for human errors and maximising quality results. Integrated camera: This allows operators to monitor the progress and quality of the installation easily. Interface screen: The touch-screen interface is a user-friendly system that allows operators to input job specs and receive automatic pullback speeds. Long working time: The bluelight resin only cures when exposed to bluelight, 444 to 457 nanometres, which allows installers extended working time, reducing time pressures. The Bluelight LED CIPP system will be available through SECA from February 2024 for all pipeline rehabilitation projects – big or small.

NordiTube’s inserted hose pressure liner lands in Australia With more than 40 years of cured-in-place pipe (CIPP) lining experience, NordiTube Technologies has brought the next level of pressure liners to Australia.

ordiTube customers profit from scale production, and its manufacturing facilities in America, Vietnam, Europe and China, which creates more economic prices and lower lead times. This extended research and development (R&D) structure allows the company to maintain technical leadership, and high-quality products. One result of this is the IH Liner. Inserted hose (IH) liner technology for pressure pipe rehabilitation was first developed in Europe more than 20 years ago. This technology is effective for long distance pressure pipe rehabilitation. So far, this technology had been limited on diameters up to DN500. Now, NordiTube has brought the IH technology to the next level, by producing pressure liners up to DN1200. Used for the water, sewer main, gas, hot temperature, and oil industries, the IH system range is between 50mm–1200mm and is AS/NZS 4020 approved. The IH Liner only requires standard equipment, including a winch, air compressor and a IH tool kit, with supervisor training provided for first installers by NordiTube. In New South Wales, Sydney Water utilised this game-changing product on its Strathfield Sewer Rising Main project. DN750 sewer rising main rehabilitated in the streets of Sydney using the IH Liner.

The rehabilitated section posed a challenge for the designers because of the location and the diameter of the pressure pipe. The line was located under two busy roads and a school, which meant that open dig pipe replacement was immediately out of the question. To add further challenges, the project had to be completed within a two-week timeframe. In total, the length to be rehabilitated was 320m of 750mm mild steel cement lined pipe. The IH Liner, capable of large diameters, allowed the designers the opportunity to match the time frame, diameter size and pressure rating for this challenging project. After the cleaning, the IH Liner installation was achieved over four days. The set-up of the liner, including the equipment assembly, only took half a day. On the second day, the pulling-in was accomplished, with took three hours for the entire 320m length of DN750 liner. Once this was completed, the liner was expanded the next day with an air compressor unit to establish its pre-set round shape. The Sydney Water team later installed the two connectors, before a pressure test was conducted, and the line then ready for reconnection. “We are glad that we could provide Sydney

The 320m length section under a school and two busy roads initially posed a challenge for the designers before implementing the IH Liner.

Water with a technology for the trenchless rehabilitation of large diameter pressure pipes,” NordiTube Asia Pacific Business Development Manager Marc Luksch said. “Next to the IH Liner, with the WSAA and AUS/NS 4020 for drinking water approved Nordiflow and Tubetex CIPP solutions, NordiTube provides now the full toolbox for pressure pipes of all sizes and lengths to customers in Australia and New Zealand.” Starting with its roots in Belgium, NordiTube Technologies quickly expanded to become a market leader in Europe, North America, and Asia in providing pressure rehabilitation solutions for the water, gas, industry and sewer-main markets. Now, 40 years later, NordiTube Technologies has manufacturing facilities in Belgium, Vietnam, America, and China. The company reaches its customers globally with fast and effective lead times and local technical support offices. This is achieved with NordiTube Asia Pacific’s Singapore team and NordiTube Australia Adelaide covering the technical sales support in the Asia Pacific market.

WASTE MANAGEMENT

A new level of productivity for waste management Civil and trenchless drainage specialists M. Tucker & Sons has expanded its services with the introduction of slurry bins, offering a comprehensive solution for horizontal directional drilling slurries, non-destructive digging slurry, drain cleaning debris capture, and dewatering.

hile methods such as non-destructive digging (NDD) and horizontal directional drilling (HDD) are efficient alternatives to mechanical excavation, the resultant waste products associated with the trenchless industry, remain a top priority for many companies when considering waste management practices. M. Tucker’s new slurry bins and circular construction materials model are one solution to tackle this problem. “Using innovative technology to maintain environmentally responsible practices has always been at the heart of what we do,” M. Tucker & Sons Business Development Manager Callan Hill told Trenchless Australasia. “Our slurry bins help our customers with streamlining disposal processes, improving onsite accessibility and saving costs, so that they can complete their projects efficiently and effectively.” How it works The slurry bins have a capacity of 8500L with a 825mm ground-to-tipping-edge clearance, and are used for onsite disposal of HDD and hydro excavation slurries, de-watering stormwater waste, sewer waste and more. “Our service ensures that vacuum tanker and hydro units stay right where they’re needed most – onsite¬ and mitigating most risks around chain of responsibility issues with large trucks carrying heavy slurry,” Hill said. “As a result, this not only minimises

and having to leave site during critical phases of projects.” With the addition of 24/7 scheduling and the removal of out-of-hours plant fees at disposal location, M. Tucker’s slurry bins provide an array of cost saving benefits.

Companies can streamline their disposal process with the slurry bins.

downtime, but maximises productivity.” By utilising these slurry bins, companies also streamline their disposal process and remove wait times associated with offsite disposal. “Our bins eliminate turnaround time, allowing our customers to focus on progressing their projects seamlessly,” Hill said. “By eliminating the delays associated with disposal logistics, our slurry bins enable customers to condense project durations.” Another crucial benefit of M. Tucker’s slurry bins is improving road safety by reducing the risk of overweight vehicles on public roads. “As our slurry bins stay onsite, multiple loads can be taken to the disposal site at once, minimising any possible chain of responsibility concerns,” Hill said. “Access to multiple bins for on-site storage creates a substantial reservoir of slurry capacity. “This eliminates concerns about trucks filling

A sustainable resource The introduction of M. Tucker’s slurry bins goes hand-in-hand with M. Tucker and Sons existing recycling and re-use process that transforms materials from waste, typically destined for landfills, into reusable resources for customers. The process is completed through the company’s EPA licenced waste disposal facility based at M. Tucker’s headquarters in Mount Evelyn, east of Melbourne. “We process over 10 million litres of stormwater debris and NDD/drilling mud combined annually,” Hill said. “We recognised the limited options for waste disposal in Melbourne and designed a wet waste recycling facility, ensuring waste generated can be disposed of locally.” The facility includes a washing and sizing plant that allows waste to be recycled into repurposed materials such as concrete, sand, aggregate and topsoil. Hill said the use of these recycled resources reduces the need for traditional quarry materials, which is becoming constrained due to demand and natural resources depleting and the demand for recycled construction products increasing.

The introduction of slurry bins continues to build upon M. Tucker’s mission for sustainable solutions.

28 TRENCHLESS AUSTRALASIA DECEMBER 2023

WASTE MANAGEMENT

However, he said the most important part is the reuse of these materials helping reduce the carbon footprint and closing the recycling loop. While the company accepts wastage from NDD and HDD projects, it also can utilise roadside verge, drain cleaning material, street sweepings and excavated fill. Once material is received at the facility, it is assessed and categorised. All reclaimable material is extracted and only the associated small portion of clays and contaminants are transported for appropriate disposal per EPA guidelines. A holistic approach As trenchless solutions continue to positively impact modern infrastructure, so too does responsible waste management. “We are proud to be part of the solution when it comes to providing responsible waste management solutions for our customers,” Hill said. “Our focus on providing a holistic service has allowed us to build a reputation for reliability and excellence.” The introduction of its slurry bins continues to build upon M. Tucker’s mission for these solutions, demonstrating the company’s approach to quality assurance, with the customer as the focus.

The slurry bins have a capacity of 8500L with a 825mm ground-to-tipping-edge clearance.

The rise of kwik-ZIP’s UK presence kwik-ZIP is continuing to use its expertise around the world, with the company’s products recently being utilised in a project in the UK.

Forches Cross LTS Diversion in the UK using kwik-ZIP HDX-90 spacers.

he kwik-ZIP HDX-90 spacers were recently utilised on a gas main crossing in Devon, Southwest England. The Forches Cross LTS Diversion involved the sleeving of a 40m 500mm OD API 5L steel pipe (also known as L360 pipe) into a 1200mm ID concrete sleeve. The diversion was required in preparation for work on the new North Devon Link Road which was designed to reduce pressure on surrounding roads and provide access to a new housing development in the area. kwik-ZIP’s large range of spacers cater for a variety of carrier and casing pipe size combinations as well as providing flexibility to deal with different project requirements.

The HDX Series has a unique load-sharing design. It is designed to maximise the loadbearing capacity of each runner while reducing point loading. The simple and efficient installation process does not require any special tools. The HDX casing spacer comes in four runner heights, ensuring that pipeline installers can handle a range of carrier pipe outer diameter and casing inner diameter combinations. This flexibility also grants installers the ability to customise pipe position for grade control. The spacers incorporate low friction, high abrasion-resistant wear pads attached to loadsharing runners. The outside diameter of the carrier pipe determines the number of segments required for each spacer and installation is simple, requiring only a screwdriver. The HDX Series can handle steel, DICL, HDPE, concrete and MSCL carrier pipes in a range of sizes. kwik-ZIP’s HDX Series further minimises potential damaging vibration and movement transfers from the outer casing to the carrier pipe via innovative suspension and dampening technologies. Use of spacers in the UK is becoming more of a standard practice and contractors appreciate the advantages that kwik-ZIP spacers provide. This includes reduced insertion forces and carrier pipe protection during sliplining, as well as quick and easy installation processes. In Australia, kwik-ZIP’s HDXT & HDX Series spacers have been successfully appraised by the Water Services Association of Australia (WSAA), with both products one of the only casing spacers on the market to be approved as compliant by WSAA. The WSA PS-324 Product Specification The Forches Cross LTS Diversion involved the sleeving of a 40m 500mm OD API 5L steel pipe.

Centralisers putting trenchless projects on the right line Traditional centralisers have several limitations that can increase risk on trenchless pipeline projects, resulting in time and cost blowouts, and reducing accuracy. But all hopes are not lost, thanks to OptionX Group’s Riteline Centralisers.

ith the confidence that Riteline Centralisers, a new fully adjustable spacer system on the market, would ensure accurate installation of product pipe, Edge Underground has used these casing spacers to successfully complete a sewer pipeline project. Riteline in action Edge Underground was contracted by West Region Delivery Team (WRDT) to install the Austral lead-in pipe for Sydney Water’s Austral Leppington Wastewater project. The project will provide safe and reliable drinking water and wastewater to service growth in the Austral and Leppington precincts.

The project involves the construction of a new pumping station, a temporary pressure main, and the construction of three carriers: Kemps Creek Carrier, the Austral Carrier and the Bonds Creek Carrier. As part of the project, Edge Underground installed 477m of DN 300 glass reinforced plastic (GRP) in a DN 500 mild steel casing, with bore lengths varying from 87m to 140m in length. Ground conditions varied along the length of the bore, from sandy clay to shale up to 40 MegaPascal (Mpa). Edge Underground Managing Director and OptionX Group Chief Executive Officer Stuart Harrison said the team used Riteline

Centralisers on the project to create 75mm spacing around the product pipe. The company then grouted thereafter to ensure a neat fit inside the 500 casing to maximise precision. “Riteline Centralisers come in both rigid and flex series depending on project requirements,” he said. “For the Austral lead-in pipe, we chose to use the rigid series because we checked the bore and didn’t see any potential for interference that would put the centralisers under excessive load. “However, had we looked at the bore and seen the potential for interference we could’ve used the flex series, which feature a unique spring-like design that enables elastic

deformation around obstacles to prevent jamming and ensure a smooth workflow.” Harrison said another benefit of Riteline Centralisers on the project was their individual attachment points as opposed to centralisers banding around the pipe. This allowed grout to flow easily around them, preventing a grout plug that is often caused by standard centraliser bands. “Riteline reduces potential issues with grouting because it is tensioned on the centreline, whilst minimising flow restriction,” Harrison said. “This means if any air pockets do happen to form, the pipe is already tensioned in the right position.” A further feature that sets Riteline apart from other centralisers on the market is their extraordinary design. The centralisers are designed with very highbond adhesive strips that prevent slippage to ensure accuracy is maintained and eliminate the need for pre-wrapping or treating the pipe. Addressing the industry’s challenges Riteline Centralisers are an innovative solution that improve the accuracy of trenchless installations by ensuring the fixed position of the carrier pipe relative to the bored hole or encasement pipe. They can accommodate pipes from 100mm in diameter, with no upper limit. “What sets Riteline Centralisers apart from other spacers on the market is their ability to adjust to different heights, ranging from 30mm up to 125mm,” Harrison said. “Other casing spacers need to be purchased in specific sizes and can’t be adapted to meet changing needs on-site. “With Riteline, incremental adjustments can be made to the existing centralisers rather than requiring new centralisers of a different size, saving time, money and stock wastage.” Typically, centralisers are also designed to either slot together to fully surround the pipe or must be designed in a size that completely surrounds the pipe. Regardless of the weight or load requirements, the maximum number of centralisers is called for. This is not the case for Riteline, which can be attached to the pipe as needed and the number of spacers required is based solely on the load, providing a tailored and efficient solution. This unique feature minimises the use of excess product, thereby reducing costs and environmental impact. “As each centraliser is individually attached to the pipe, the risk of catastrophic failure is reduced,” Harrison said. “Traditional centralisers that surround the pipe can fail when they snag on an obstacle in the bore, which can cause an entire ring of centralisers to move, compromising the installation.” The benefits of Riteline Centralisers also go beyond the project site.

Riteline Centralisers are an innovative solution that improve the accuracy of trenchless installations.

“Traditional centralisers are notorious for causing cut injuries during the installation process,” Harrison said. However, Riteline is manufactured from durable engineering polymers. “Without the thin sheets of metal often seen, the risk of these injuries is removed,” he said. “Coupled with their easy installation, that chance of workplace injuries is reduced.” Australian owned and made Edge Underground has been developing by using and providing feedback on Riteline for almost 10 years. As a result, the product is now available on the wider market, with both Edge Underground and Riteline being owned by OptionX Group. “Riteline Centralisers are Australian owned and made,” Harrison said. “And we are pleased to say all are now currently undergoing Water Services Association of Australia (WSAA) approval.”

With Riteline, adjustments can be made to the existing centralisers, saving time, money and stock wastage.

of around 20m. Online Pipe Crew Leader of CCTV/Robotics Dave Blackmore contacted IBAK to check whether the MicroGator Air cutter could be integrated into the existing system, which was first purchased three years ago. As the MainLite concept is designed as a modular system with interchangeable components, this made it easy to add additional functions. For IBAK, it was a perfect opportunity to introduce the MicroGator Air cutter in Australia. Online Pipe & Cable Locating Managing Director Barry Maloney praised the

performance of the MiroGator Air cutting robot as soon as after the first use. “As we already had experience with other cutting systems, we actually only wanted to test the IBAK cutter for this job,” Maloney said. “However, the results were so convincing that we decided to keep the device straight away. “The investment in the MicroGator Air has significantly improved our productivity in terms of the possibilities for cutting work.” Now, the company benefits from the range offered by this system, as the MainLite system is compatible with the MicroGator Air cutting robot, allowing for both inspection and highperformance cutting. Since 2014, IBAK Australia has supplied customers with inspection and robotic systems, both available as portable systems and as component-based systems for installation in vehicles. The company also provides professional maintenance and repair services in Silverwater, New South Wales, which is key to its proper customer support. In early 2023, IBAK Australia entered a partnership with USB Australia, resulting in Shannon Moroney being appointed as a contact person for customers. IBAK International Sales Specialist for Robotic Systems Frank Claaßen said Moroney now supports distribution of the high-quality systems with a strong focus on the end client’s needs. “By having Shannon on board, IBAK Australia is happy to promote the sales in Australia with more in-field demonstrations with our demo vehicle which supports our CCTV equipment as well as our MicroGator Air cutting system,” Claaßen said.

HDD

A holistic approach to HDD project management Maxibor Australia Chief Executive Officer (CEO) Rodney O’Meley spoke to Trenchless Australasia on minimising risk and optimising outcomes for stakeholders in horizontal directional drilling (HDD) projects. in these critical phases allows for real-time assessment of risks and the implementation of mitigation measures. Cost management – Recognising that pipeline installation accounts for a significant portion of HDD project costs (circa 65 per cent), O’Meley’s experience and decision-making can lead to more productive operations, reducing labour and equipment expenses. Operational expertise – The operational management team complements O’Meley’s ownership. Their specialised expertise in areas such as design, estimating, project management, commercials and HSEQ ensures the day-to-day efficiency and safety of HDD projects. Maxibor applies this approach to the extreme inherent risk areas of geotech investigation, installation – pilot hole, and installation – pipe pull.

ith over 40 years of experience under his belt, O’Meley combines his hands-on ownership with an experienced operational management team. The Maxibor operational management team also has a wealth of experience in the design and delivery of HDD projects spanning several decades. HDD risks The inherent risk of an HDD project is largely concentrated at the geotech, design and pipeline installation stages of the project. Inherent risk is the level of risk when no action has been taken to mitigate or reduce the risk. It is the risk before any treatments or controls are put in place to mitigate the risk. Residual risk is the level of risk that remains after controls have been put in place. Developing mitigation actions to respond to those activities with higher inherent risk will substantially benefit from the involvement of people with wide experience in solving a variety of HDD project challenges. Maxibor Australia’s perspective on the management of HDD risks involves multiple stages. Ownership commitment – O’Meley’s direct involvement as both CEO and owner demonstrates a high level of commitment and passion for the HDD business. This 42 TRENCHLESS AUSTRALASIA DECEMBER 2023

conditions, and make necessary adjustments before proceeding to the reaming and pipe pull stages. This proactive approach reduces the risk of unexpected challenges during subsequent phases. Efficiency and cost savings – A well-executed pilot hole not only ensures accuracy but also increases project efficiency. It reduces the time and effort required for reaming and pipe installation, ultimately leading to cost savings in terms of labour and equipment usage. Installation – Pipe pull The pipe pull phase is the culmination of the HDD project, where the pipeline is pulled through the drilled borehole. Maxibor pays particular attention to this phase for a successful project completion. Alignment and precision – The alignment of the pipeline during the pull is crucial. Maxibor ensures that the pipeline aligns precisely with the intended path established by the pilot hole. This precision avoids issues such as misalignment, bends, or kinks that could affect the pipeline’s performance or durability. Friction reduction – Reducing friction and resistance during the pipe pull is vital to prevent damage to the pipeline, drilling tooling, and the borehole itself. Maxibor uses proper lubrication techniques and closely monitors the pulling force to ensure a smooth and controlled pull.

The pipe pull phase is the culmination of the HDD project.

involves assessing geological conditions, soil types, rock formations, caverns, and potential obstacles in the drilling path. Risk assessment – Maxibor assesses these hazards as project risks, quantifying the level of risk associated with each identified hazard. This step helps prioritise risk mitigation efforts based on their potential impact on the project. Risk mitigation planning – The company identifies required actions to manage ground risks effectively. This includes developing strategies to navigate challenging geological conditions, such as fractured rock drilling techniques or the use of specialised tooling. Documentation and linkages – The geotechnical investigation informs the development of design and construction documentation. These documents include plans and procedures tailored to address specific ground conditions and associated risks. They are linked to the construction program to ensure seamless execution.

Installation – The pilot hole is a critical component of HDD projects, setting the stage for the subsequent drilling and pipe installation phases. Here’s how Maxibor manages the pilot hole process. Precision – Maxibor emphasises precision and accuracy during the pilot hole process. This involves the use of advanced steering and guidance equipment to navigate through complex subsurface conditions, including rock formations, utilities, and environmental obstacles. Environmental impact mitigation – Maxibor minimises the environmental impact by starting with a smaller-diameter borehole during the pilot hole phase. This reduces disruption to the surrounding area and lessens the likelihood and impact of environmental damage. Subsurface assessment – The pilot hole serves as an essential tool for assessing subsurface conditions. It helps identify potential obstructions, assess ground

Quality assurance – The pipe pull phase serves as a quality assurance checkpoint. It allows for a final inspection of the pipeline to identify any damage or defects that may have occurred during the installation process. Any issues are addressed before the project is considered complete. Efficiency – Efficient pipe pulls help control project costs by reducing labour and equipment expenses. They also minimise potential delays associated with rework or corrections, contributing to overall project efficiency. Maxibor’s approach to HDD projects emphasises the meticulous management of higher inherent risk areas such as geotechnical investigation, pilot hole drilling, and pipe pull installation. By integrating ownership thinking, technical expertise, risk assessment, and mitigation strategies into these critical phases, Maxibor optimises project outcomes while ensuring precision, efficiency, and environmental responsibility. This comprehensive approach demonstrates the company’s commitment to delivering successful HDD projects that meet the needs of all stakeholders.

Maximise HDD accuracy with combined guidance technologies As the underground grows more crowded, the industry is under pressure to deliver highly accurate installations through a web of existing infrastructure.

ector Magnetics Director of Marketing Jed Sheckler discusses in Trenchless Australasia how the trenchless industry can palliate this pressure through horizontal directional drilling (HDD). HDD has become an essential part of the expansion and replacement of critical data, electrical, water, energy, and waste networks, with proven effectiveness across a diverse range of installations. Exploring the practical limits of HDD accuracy has become a popular topic of discussion within the trenchless community. In a year when both the North American Society for Trenchless Technology (NASTT)

Table 1: Categorisation of available HDD guidance methods.

and European Drilling Contractors Association (DCA) are updating their best practices and guidelines, it is important to have a clear understanding of the role of guidance systems in maximising the accuracy of the HDD process.

Figure 1: Surveyed position is calculated relative to a single tie point.

Figure 2: Tracking provides additional tie points enhancing survey accuracy.

utilised by rigs of any size. The term downhole more appropriately describes a guidance system capable of operating without surface access, and with no inherent depth limitation. Downhole systems may be classified as magnetic downhole, gyroscopic downhole or combo systems. As shown in Table 1, there are several methods of guiding a HDD pilot bore. While details may differ depending on the manufacturer’s approach, a complete HDD guidance system must provide the following capabilities: • Steering puts the directional in HDD: The drilling assembly is fitted with an offset bit, sub, or motor. An accelerometer in the steering tool informs the driller of the current inclination and roll-angle. Orienting the offset and pushing (sliding) the drill string without rotation provides directional control of the borehole. • Surveying calculates the location of the pilot bore as it progresses: Surveys are taken at discrete positions (typically when making a drill rod connection) when there is no fluid flow, and the sensors are most stable. HDD survey tools (downhole magnetic or

gyro) measure the orientation of the tool relative to the earth’s poles (azimuth) and gravitational field (pitch). These values are combined with total drill pipe length (measured depth) to calculate the current position relative to a known starting point, typically the bore entry point (Figure 1). • Tracking verifies the calculated survey position by making direct measurements relative to external reference points. A tracking source (ParaTrack2 electrical cable, Beacon Tracker, Microcoil, etc.) is placed at a known location on surface or run through an adjacent, completed conduit. The source is periodically electrified and emits an electro-magnetic signal sensed by the magnetometers in the survey tool. The signal is emitted from a known location, at a known intensity, at a known frequency, providing a series of additional tie points that greatly increases the accuracy of the surveyed position (Figure 2). Sources of error While technological advancements have greatly improved the quality of HDD surveys, it is important to understand the types of errors that may act independently or in combination to influence the accuracy of an HDD guidance system. Random errors are unpredictable and may appear as though no one sample repeats (low precision). However, the impact of random errors is minimised by increasing the sample size and averaging. Adequate sampling makes it possible to obtain accurate answers from highly random data sets. Systematic errors are consistent and reproducible, imparting a bias to the data. When drilling on survey data alone, without the benefit of additional tie points from an external tracking source, systematic error will typically become the main source of positional uncertainty over longdistances (>300m). Gross errors are, in short, typically caused by human error. Gross errors can be

especially difficult to detect as they cannot be modeled or effectively planned for. Gross errors include input errors (moving a decimal point), transcription errors (flipping a sign, transposing a digit), or operational errors due to a lack of training, etc. Ellipse of uncertainty While all three types of errors may act independently or in combination, it is widely accepted that the majority of borehole surveying uncertainty is due to systematic errors in the surveying system. Small errors in inclination, azimuth, and depth systematically accumulate. This accumulation forms an ellipse of uncertainty regarding the true position of an inclined borehole that grows as a function of drilled length (Figure 3). Maximum accuracy, minimum risk. The positional uncertainty that results when a pilot bore is guided from a single tie point presents a risk that all parties must be aware of when considering the available technology. A guidance system combining a precision survey (gyro or magnetic) with secondary tracking (ParaTrack2 electrical cable, Beacon Tracker System, Microcoil) that identifies and corrects for any induced error results in the highest achievable accuracy for HDD (Figure 4). Modern HDD job sites fuse the latest technological advancements with the realities of getting product in the ground. Above all is the need to identify potential sources of risk that could slow progress, result in an accidental strike, or worse yet, cause the project to fail entirely. A clear understanding of the capabilities and limitations of available guidance technology ensures constructable designs with tolerances that can be realistically followed, maximising the chances of a successful outcome.

The team at APEX Utilities in Perth.

From little things, big things grow Formed off the back of 20-plus years of friendship, APEX Utilities is a Western Australian team specialising in replacement mains and services in urban areas.

he company’s strengths have been driven by a leadership team who have built vast experience through their roles within both privately owned businesses, and tier 1 utility providers. General Manager Brett Tedman said the APEX Utilities team has successfully delivered some of Western Australia’s most significant replacement projects for clients such as ATCO Gas, Water Corporation, Western Power, and NBN CO. This has been achievable thanks to Vermeer Equipment of WA & NT’s HDD drills – the Vermeer D23 X 30 S3 horizontal directional drill and the Vermeer D10 X 15 S3 horizontal directional drill. “Vermeer’s machines have allowed us to drill longer distances in a day due to it being class-leading and having 140m of 48 TRENCHLESS AUSTRALASIA DECEMBER 2023

rods compared to other rigs on the market” Tedman said. “This results in an extra 20m being drilled a day, and with that being a big part of the service we provide our clients, it improves our efficiencies and lowers the overall cost of the project for the client.” With a 99 dB(A) guaranteed sound power level and an operator ear rating of 78.7 dB(A), the D23x30 S3 makes a quiet working environment possible, creating less neighbourhood disturbance and enabling easier communication among the crew. Due to this lower sound power level, APEX Utilities has been able to use the Vermeer rig to complete works at night without causing too much noise. Bosting 24,000lb of thrust/pullback and 3000ft-lb of rotational torque, the D23x30

S3 also offers a sizeable increase in power over its predecessor, the D20x22 Series II — helping to maximise machine and jobsite productivity. Featuring a short, narrow design, while its 100 hp Deutz engine offers the power operators need when working in tough ground conditions, the rig can track up to 5.3km/h, helping operators get into position for their next shot more quickly. The D10x15 S3 stands out due to its compact design and light weight. With 10,000lb of thrust/pullback and 1500ft-lb of rotational torque, it has the power required for tough ground conditions and pulling reamers. Tedman said the team at APEX Utilities have used Vermeer’s machines since 2002, when it was a former company. “Since Apex Utilities’ inception in February

2022, we have always turned to Vermeer Equipment of WA & NT for our fleet,” he said. “Our relationship with Vermeer Equipment of WA & NT has turned more into a friendship these days and we have been able to build a really strong foundation where we look out for them and they for us. It is these similarities in values which the team at APEX Utilities really values. Director Russel Scheffer founded APEX Utilities after working within the utilities industry for over 15 years. With extensive hands-on experience in the utilities, civil and construction industries extending to all aspects of field operations, he has a strong risk management approach to business, ensuring all potential risks are mitigated and managed through all aspects of company performance and compliance. His main focus is on the overall direction and operational performance of onsite operations; aiming to provide positive leadership, coaching and development of a positive culture and long-term growth strategies. Both Tedman and Scheffer have put a big emphasis on the wellbeing and success of its employees, and about creating a safe, fulfilling, and engaging work environment. APEX Utilities also delivers progression and development of its team through internal and external training.

It has also cultivated a program to encourage women who are interested in the trenchless industry a pathway where they can learn all aspects of the business. “Following covid, we found a lot of women who had either lost their job as a result or were looking for a career change,” Tedman said. “We thought, well, there’s got to be a market there so, let’s now focus more on female engagement which has resulted in 35 per cent of our workforce being women.” “This has given us a real competitive edge and as a result allowed us to employee some very talented people. “We’re making sure they can operate the rig, they can fit up the mains, weld, test and clean pipes, and do the entire cycle, because we’re not just the drilling company, we’re an end-to-end business and our mentorship allows this.” Tedman said that at the end of the day, APEX Utilities isn’t just a blue-collar company, but a family business. And through this family unity, it has been able to grow steadily to 12 employees, work on major projects, and establish strong relationships with businesses such as Vermeer Equipment of WA & NT. “The core belief between both businesses is relationships,” he said. “Every single aspect of the business, regardless of how big the contract is, we choose to keep the relationships strong.”

Horizontal directional drilling: What’s in it for utilities? In the world of utilities, pipe and cable installations are a routine process. On such projects, getting the job done quickly and effectively is the primary objective.

or this reason, it’s important for utilities to take advantage of technological innovations and seize any opportunity that will facilitate the streamlining of these processes. Cable and pipe installations often employ open cut trenching techniques, which – although successful at getting the job done – are tedious, time consuming, expensive, and can result in significant environmental and community disruption.

Vermeer’s HDD range is versatile enough to go almost anywhere and drill through any surface.

50 TRENCHLESS AUSTRALASIA DECEMBER 2023

Revolutionising underground utility installations When it comes to ticking the boxes for minimal disruption, efficiency and effectiveness in pipe and cable installations, horizontal directional drilling (HDD) has it covered. HDD is a method of installing underground cable, pipelines, and service conduit without the messy open cut trench. HDD offers some unique advantages when compared to other underground utility

installation and traditional open cut methods. HDD negates the need to dig up large amounts of earth and relocate the displaced dirt and slurry, making it a faster and more efficient method of digging. As well as its time-saving benefits, HDD offers significant cost savings for contractors, with faster job completion meaning reduced labour costs. HDD requires less dirt to be extracted, and as such there is less dirt that needs to be replaced.

HDD

Further cost saving benefits are delivered by HDD’s smaller footprint, meaning less permits need to be purchased to conduct work, and the need to compensate businesses due to area disruption is removed. Boasting a much smaller physical footprint than other open trench projects results in less community disruption, as HDD removes the need to cordon off large areas for construction. This also has environmental benefits, as HDD has significantly less impact on the surrounding earth, which is especially critical in environmentally sensitive locations. When it comes to utilities delivering optimal results, they need to be using the finest tools.

industry. Offering an impressive range of equipment, Vermeer is a top choice for HDD machinery of choice around the world. From heavy duty rigs for large-scale installations to smaller, more flexible rigs, Vermeer’s HDD range is versatile enough to go almost anywhere and can drill through almost any type of earth. As well as delivering increased efficiency and effectiveness, the company’s range

prioritises accuracy, with some of the larger Vermeer drill rigs offering interactive, full colour displays that provide real-time location information, potentially replacing the need for hard copy bore plans.

2023 IN REVIEW

Rob Carr is in charge of the trenchless design and construction of the Brisbane Creek Trunk Sewer Main Upgrade project.

Reflecting on 2023 From constructing major water pipelines to rehabilitating a 100-year-old sewer, Trenchless Australasia looks back on the biggest stories of 2023.

t the beginning of 2023, microtunnelling contractor Rob Carr began construction of a 1km long wastewater Breakfast Creek Trunk Sewer Main Upgrade, running under the heard of Brisbane, Queensland. In Victoria, Greater Western Water’s contractor Jaydo Construction commenced works on stage two of Melbourne’s Victoria Street Main Renewal project. Similarly, in Watsonia, the North East Link continued its progress with piling works now complete. In New South Wales, the Sydney Metro West project saw a significant milestone with tunnel boring machines (TBMs) Daphne, Beatrice and Betty beginning their journeys. Rob Carr begins construction of important Brisbane sewer in $45m Urban Utilities project The Urban Utilities project is part of a major infrastructure upgrade to cater for population growth in the city’s north. Contracted by Urban Utilities’ delivery partner Fulton Hogan, Rob Carr utilised a 29-tonne Herrenknecht microtunnell boring machine (MTBM) named Leila Perry for construction of the sewer. “We have a strong reputation as a leader and innovator in the industry with a proven track record of delivering high-quality 52 TRENCHLESS AUSTRALASIA DECEMBER 2023

work,” Rob Carr General Manager Angelo Soumboulidis said. “Working closely with our client, Fulton Hogan Utilities, our innovative final design solution minimised disruption to the surrounding community and limited environmental impact. “Our commitment to providing innovative solutions to our clients’ needs and our dedication to delivering exceptional customer

service were also key factors in our selection for this project.” As of August 2023, the MTBM finished its 1km journey and broke through at the retrieval shaft. Rob Carr will now undertake high density polyethylene welding of the pipe joints, while also carrying out the second stage of the S1 tunnel connection. Construction is expected to finish in 2024. Jaydo Construction commenced work on stage two of Melbourne’s Victoria Street Main Renewal project.

Link green bridge over Bulleen Road as well as three new wetlands along the Yarra River and Koonung Creek in Bulleen and Balwyn North. In September 2023, the first parts of the TBMs travelled to Watsonia, with more than 20 super loads arriving progressively in three shipments over the next six months. Once all the segments arrive on site, the two TBMs will take around six months to be assembled. Construction of the North East Link Tunnels are expected to complete by 2028.

The North East Link Program completed piling works, forming the TBM launch area.

Greater Western Water’s renewable project hits next stage In April 2023, Jaydo Construction commenced work on stage two, which involved replacing 1.8km of water mains down Rathdowne Street and along the southern side of Victoria Street, between Exhibition Street and William Street in Melbourne. Stage one first started in August 2022, with the successful relining of 250m of water mains along Howard Street, North Melbourne as well as 1.7km of water mains along the north side of Victoria Street, between Howard Street and Nicholson Street. Greater Western Water General Manager for Growth and Infrastructure Amanda Smith said that ageing infrastructure is the main reason behind the works. “The upgrade will create more capacity in the system and help ensure the water supply remains clean and reliable for our customers across North Melbourne, Carlton and the inner city,” Smith said. “It will also prevent water network faults, reducing disruptions and improving customer experience of our services into the future.” The project is expected to reach completion in early 2024. North East link taking shape in Watsonia April 2023 marked the completion of the piling works for the North East Link Program within its site on the east side of Greensborough Road, Watsonia. This formed the structural foundations of the TBM launch area. “About 7400 cubic metres of concrete was used for the box piles alone (almost 19 elephants’ worth) and if you stacked each

pile end to end, it would be almost 7.2km long,” the North East Link Program team said at the time. The North East Link Tunnels will take 15,000 trucks off local roads every day and reduce travel times by up to 35 minutes. This will be made possible thanks to longer tunnels of 6.5km to Watsonia, simpler interchanges at Lower Plenty Road and Manningham Road, 5 MCGs of parklands along Banyule Creek at Borlase Reserve, a new 2km tree-lined boulevard for Greensborough Road, a 2-hectare Yarra

Sydney Metro West project hits next stage By connecting Greater Parramatta and the Sydney CBD, Sydney Metro West aims to double the rail capacity between Sydney’s two biggest CBDs once passenger services commence in 2030, to support a growing city and deliver world-class metro services to more communities. TBMs Daphne and Beatrice began their journeys in June 2023, while TBM Betty began tunnelling in September. At the time of publishing, TBM Daphne had reached 3.14km of her 11km journey, Beatrice had reached 3.46km, and Betty had reached 124m. These TBMs are three of six mega TBMs to build Sydney Metro West. Construction on the project first started in 2020. The 24km metro line has stations confirmed at Westmead, Parramatta, Sydney Olympic Park, North Strathfield, Burwood North, Five Dock, The Bays, Pyrmont and Hunter Street in the Sydney CBD.

TBMs Daphne, Beatrice and Betty all began their journeys for the Sydney Metro West project this year.

WOMEN IN INDUSTRY W O M E N I N I N D U S T R Y. C O M . A U

Women in Industry returns for 2024 The 2024 event will be hosted in Sydney following this year’s record-breaking ceremony.

he 2023 event was memorable for countless reasons. One of them being Woman of the Year and Safety Advocacy awards recipient Giselle Phillips. Sitting down with Trenchless Australasia to reflect on the awards, Phillips said it was “thrilling – a different city, with a different vibe and just being a finalist was exciting”. “I met so many wonderful women and male allies across a variety of industries,” she said. Phillips said she will be in attendance at next year’s awards, taking place on Thursday, 20 June 2024, and was looking forward to it. “By celebrating and encouraging, Women in Industry benefits not only women themselves but also their organisations, the economy, and society at large. It is a fundamental step towards building a more equitable and prosperous world,” she said. “I want to be able to meet, connect and celebrate with the many women that are championing and actively contributing to their industry.” For Phillips, events like these are vital for recognising the place of women in traditionally male-dominated fields “because they create a supportive, empowering, and inclusive environment that recognises, acknowledges and celebrates women’s contributions”. “While also pushing for positive changes in industries and society as a whole,” she said. Also playing an important role in the success of the event, is the support of The Women in Industry’s valued sponsors, such as Fulton Hogan, who just renewed its partnership for 2024. Fulton Executive General Manager Sarah Marshall said the company was thrilled to be supporting such an impactful event. “I’m so thrilled that we’ve been able to renew our sponsorship, it demonstrates our commitment to improving gender diversity in not just our own business but within the industry as a whole,” she said. “We believe that we’re setting the standard for other construction and infrastructure companies to follow suit.” As the most coveted award on the roster, Fulton Hogan was thrilled when the company 54 TRENCHLESS AUSTRALASIA DECEMBER 2023

was given the opportunity to sponsor the Women of the Year award. “Women continue to be underrepresented in our industry and we’re proud to shine a light on some of the incredible work that is happening across a range of industries,” Marshall said. According to her, it’s crucial to celebrate the achievements of those within the industry, and especially those who are pushing boundaries and driving change in predominantly male industries. “I’m a firm believer in the fact that you can’t be what you can’t see.” A statement seconded by Fulton Hogan Infrastructure Services National Communications and Stakeholder Manager Nina McHardy. “In predominantly male industries it’s important to lift females up – to celebrate their respective success but also to demonstrate to those that are following in their footsteps that whilst females are in the minority, they are still so important and deserve to be celebrated,” she said. “We’re looking forward to seeing the incredible nominations as well as hopefully celebrating the talent that exists within our business.”

McHardy said this event is a way to give back to women and the businesses who champion them. “It is also great to celebrate the businesses that support them – after all we all want to work for an employer who appreciates diversity and is taking steps to improve it within their business awards such as this are a great way to showcase supportive businesses as well as the great talent that sits within them.” Four sponsors have been confirmed for the 2024 awards including Atlas Copco, COG Advertising, Fulton Hogan, Komatsu, PACCAR Australia, SEW EURODRIVE and Kenter. With 11 categories available for sponsorship, there are numerous benefits to securing sponsorships. These include promoting corporate values as an equal opportunity employer; with progressive policies encouraging women in management as well as networking among peers and influencers in mining, manufacturing, engineering, and commercial road transport industries.
