McConnell Dowell sets world record

The company has set a new Direct Pipe® world record for the longest single drive by a micro tunnel boring machine (MTBM).

McConnell Dowell completed the drive on Watercare’s Snells Algies wastewater pipe and outfall project with the MTBM setting a record of 2021 m, surpassing the previous mark set in New Zealand by record 92 m.

The Herrenknecht machine bored through challenging geology and a curved alignment to complete its work during the COVID-19 lockdown after being deemed an “essential” project.

McConnell Dowell Project Manager Brent Whiting says the record achievement demonstrates the depth and skill of experience in the company’s tunnelling teams and its dedication to working through challenges.

After its breakthrough, the MTBM was driven into a trench off the coast of Martins Bay where it will be separated, lifted and transported to a local harbour.

The project is the first phase of Watercare’s three-stage scheme to supply the surrounding communities with reliable wastewater services.
