Alice breaks through
After a two-year journey, 3,400 tonne tunnel boring machine (TBM) Alice has broken through the final 900 mm of concrete at the southern end of the Waterview Connection. The breakthrough was incident free, according to Tunnel Manager
Chris Ashton.

“Everything went to plan, it was a textbook breakthrough. Our team did real hard work pumping out the metres over various shifts and keeping Alice shipshape to complete its work to world class standards,” Mr Ashton said.

The Waterview Connection project is one of New Zealand’s largest and most challenging projects to date. Once completed the NZ$1.4 billion project will provide a motorway ring around Auckland, improving experience for commuters across the city. Alice began her journey in 2013 and is now being used to complete a drive in the opposite direction, a rare manoeuvre for a TBM.

Golden Gecko awarded to microtunnel project
Chevron Australia has been awarded the 2015 Golden Gecko Award for Environmental Excellence for an innovative shoreline crossing on the Wheatstone project. The microtunnel links a 225 km long offshore gas pipeline to the onshore processing facilities.

Microtunnelling was utilised to protect the coastal area adjacent to the Ashburton River Delta, which supports important mangrove and estuarine habitats.

Department of Mines and Petroleum Executive Director Environment Dr Phil Gorey said the project stood out to the selection committee and was a very deserving recipient of the 2015 Golden Gecko Award.

“Chevron investigated five options for a shore crossing and chose the one with the lowest environmental impact, even though it was the most expensive choice,” said Dr Gorey.

Water Corp finds a buyer
RCR Tomlinson has bought Water Corporation’s Engineering and Construction Services (ECS) Team for AU$10.4 million.

Water Corporation said the key driver for the sale was less need to build new water and wastewater infrastructure.

Water Corporation Chief Executive Officer Sue Murphy said “We are coming out of a decade that has seen major changes in the management of Perth’s water supplies. Combined with lower population growth and a successful reduction in per person water use, the need to deliver major water projects has lessened.

“Selling ECS provides the best opportunity for ongoing employment for our people – employees were given the opportunity to move across to the successful bidder, without loss of pay and conditions.”

Christchurch developing Three Waters Strategy
Christchurch City Council, New Zealand, has started a project to develop a Three Waters Strategy that will inform the council’s long-term plans, infrastructure strategies and asset management plans for many years to come.

Water supply, surface water and wastewater are the main focuses of the new strategy, which will be developed over the next year.

The council has engaged MWH and subcontractors Tonkin and Taylor, Cranleigh and Aqualinc to develop the Three Waters Strategy.

HDD under Webya Creek
Unitywater is replacing a 30-year-old section of sewer pipe that runs under Noosa’s Weyba Creek.

Unitywater is installing a new 350 m section of pipe from the northern side of Weyba Creek near the corner of Ravenswood Drive and Mossman Court, under Weyba Creek to Council land adjacent to Settler’s Cove, off Serenity Close.

The works will involve drilling 10 m under Weyba Creek, and installing a new pipe parallel to the existing infrastructure. The drilling section of the project will be carried out continuously to prevent the tunnel from closing and the drill becoming stuck.
