Leading the world Down Under

No-Dig Down Under 2011, the National ASTT Conference and Exhibition, was held with great success in Brisbane from 3–6 October. The event attracted over 1,000 participants and was one of the largest trenchless exhibitions ever hosted in the Southern Hemisphere.

Rolling out the NBN

The keynote session on the final day of No-Dig Down Under 2011 was delivered by NBN Co General Manager State Operations Rob Seal, who addressed delegates on the roll out of the National Broadband Network, including working with contractors to develop a low impact scheme, part of which involves using Trenchless Technology.

Boring ahead of schedule

The recently-completed Northern Sewerage Project is one of the largest and most ambitious sewerage tunnelling projects ever undertaken in Australia, involving the use of three tunnel boring machines under major infrastructure in Melbourne.

CIPP — where do we go from here?

Dr Dec Downey, Trenchless Opportunities Ltd

Cured-in-place pipe (CIPP) appears with hindsight as one of the most significant breakthroughs of the last century. Some 50,000 km of CIPP has been installed worldwide since 1971. For 20 years the technology was protected by substantial patents and licensing policies. The tight grip relaxed in the 1990s and vigorous competition ensued as new processes and materials were introduced.

Sydney stormwater pipes receive a makeover

2011 has been a record year for stormwater pipe rehabilitation for Insituform’s Sydney operation. A significant number of projects have been completed, with a number of them being in very high profile areas of Sydney.

Tunnelling success in Melbourne

The Melbourne Main Sewer Replacement, an historic upgrade of Melbourne’s century old main sewer, has progressed well over the past twelve months and is tracking ahead of its scheduled mid-2012 completion date.

Jacking under pressure

HOBAS has recently achieved an Australian first by facilitating the first-known use of pressured jacking pipe in Australia for the Melbourne Main Sewer Replacement project.

Major pipe jacking in Warsaw

The underground connection to the new Czajka wastewater treatment plant in Warsaw, Poland, was completed successfully and on time, earning itself the title of ISTT Project of the Year.

Flood mitigation project takes out ASTT award

The Sandgate Avenue Drain Flood Mitigation Project – Stage 1, which reduced the likelihood of floods during severe storms in Frankston, Victoria, was recently named the ASTT Installation Project of the Year.

Two cities, one continuous bore

Traversing two affluent US towns, through the suburbs of Fort Worth in Texas and beneath two golf courses, the Fossil Ridge to Arc Park project ranks among the longest continuous bores in trenchless pipeline history.

Record-breaking rockhead flies through fifth tunnel

A Robbins self-propelled tunnelling machine recently achieved a milestone in Cincinnati, Ohio, when the 1.8 m diameter Double Shield Rockhead bored 614 m — a distance that appears to be a world record for a hard rock machine of this diameter.

Pipe ramming success in Melbourne

A series of historic water pipes along William Street, Melbourne, are being replaced after more than 150 years of service. The $A20 million project will replace water pipes that were some of the first water mains laid beneath the city, dating date back to 1857.

Hose and fittings, direct to site

Win United is an energetic, family-owned company specialising in the supply and delivery of industrial hose and fittings.

Manhole rehabilitation made easy

A new technology for rehabilitating access chambers and sewer structures has arrived in Australia.

Trenchless Advisor relocates

After a successful few years, Trenchless Advisor has recently relocated to new, larger premises.
