Western Australia
Trevor Gosatti
Australia has continued to work hard and face any challenges that are presented. In doing so, a major milestone has
been reached at the Forrestfield-Airport Link project – tunnelling is now complete. The second TBM broke through
at the Bayswater dive structure at the end of April after 900 days of tunnelling, following the first TBM which broke
through nine weeks earlier. This project achievement – and the project in entirety – is a key reminder of the role
trenchless construction projects will play in WA’s COVID-19 economic recovery.
South Australia
Adam Russo
The last few months have seen the trenchless sector continue to grow throughout the state of South Australia with
many ongoing works continuing during the COVID-19 pandemic and a plethora of tenders being released for
future trenchless construction. Through March and April, regional councils employed contractors for horizontal
directional drilling work and the rehabilitation of sewer and wastewater pipelines. Currently, more tenders are
being released for trenchless road upgrades and maintenance works, including hydro excavation, stormwater
relining and CCTV inspection. Despite the challenges being faced, the trenchless industry will continue to thrive as
best it can in these unprecedented times.
Queensland
Ben Crosby
The last quarter in the trenchless industry remains busy on both a national and international level with clients
continuing to rehabilitate and install new utility infrastructure, despite the new COVID-19 world. Our Queensland
Trenchless Networking and Presentation Seminars are going well; however, unfortunately, due to COVID-19
the seminars have been placed on hold. The next Networking and Presentation Night will be held once group
gathering restrictions have been lifted. We have two presentations locked in, sponsored and ready to go;
Pezzimenti Tunnelbore on culvert rehabilitation via pipejacking and Strabag on the longest pipejacking drive in
Asia: 1,550 m x ID 2,000 mm. Contact me if you are interested in speaking, sponsoring or attending one of these
presentations in the near future. Additionally, if you are interested in joining the ASTT as a corporate or individual
member, again please contact me to discuss and gain more information. The benefits are impressive and the access
to the network makes it a very worthwhile proposition.
New South Wales
Sudipta Basu
As the new ASTT financial year begins, I welcome Matthew Boyle to take over from me as the newly elected
Councillor for NSW. With his experience in the trenchless industry, I have no doubt he will be a highly effective
Councillor. I wish him all the best. I will now continue as a Councillor but in a different role. This role will involve
activities common to the society in general, such as the implementation of the strategic plan and others as those
evolve. The role will also provide support to the State Council as needed.
New Zealand
Blair Telfer
Incredible how the world can be turned upside down in such a short space of time. I do extend my hopes and
thoughts to you all and trust that you have managed to successfully navigate yourselves, family and businesses
through these unprecedented times. As has been said on many occasions ‘through adversity comes strength’ and
knowing the nature of the workplace we work in, I am confident of the resilience of our industry to come back from
this event stronger, with good learnings, from these harsh times. It is the nature of our industry that we are agile,
innovative and problem solvers. These are the traits that we will need to rebuild ourselves. There is still a lot of
uncertainty in what the future will bring, but I urge you all to be positive and we will collectively come through this.
Stay well, stay safe, Kia Kaha, stay strong.

JUNE 2020 TRENCHLESS AUSTRALASIA 21COVID-19 Interflow manages essential employee safety While COVID-19 is forcing many Australians to stay home, plenty are still working in the field to ensure essential services such as water and wastewater continue to function. To meet these needs while ensuring employee safety, water infrastructure specialist Interflow has adapted its operations. I n the wake of the pandemic, operations at work sites have changed dramatically and essential service businesses have had to quickly adapt to restrictions and incorporate new methods, while guaranteeing customers and employees remain safe – and ensuring business continuity. As a lot of companies tackle this uncharted territory, Interflow has recognised that adaptability and communication are emerging as the best way forward. Interflow’s quick risk response Interflow Executive Manager Health and Safety Adrian Smith says the company reacted immediately when the COVID-19 pandemic took hold in February 2020 and swiftly put enterprise risk management plans in place. “COVID-19 has created significant changes to the way we work,” says Mr Smith. “We’ve implemented a business continuity plan with five response teams to identify and resolve critical issues around workforce To ensure services can continue to run for customers, Interflow workers are practicing social distancing even while onsite. protection, supply chain stabilisation, customer engagement, operational lead and lag management and stress testing financials.” Interflow is using similar parameters within its current health and safety strategy, titled Harm 2 Zero (H2O), with the new response teams meeting twice a week to discuss any issues and actions that need to be taken. Mr Smith says the company’s executive team has become the nerve centre of its COVID-19 response. Employee safety steps in the field The additional safety and procedural policies that Interflow is implementing include social distancing, which involves rethinking the way crews work; reinforcing hygiene by providing COVID-19-appropriate level of PPE for workers; ensuring current signage across all sites; and providing teams the right information so they understand all new company procedures. “We’re currently developing a second communication pack for workers, with updated rules of engagement, and every week our Managing Director creates a video message to Interflow has altered its operations to ensure the safety of the community and its essential workers. 22 TRENCHLESS AUSTRALASIA JUNE 2020
