Pezzimenti Trenchless hits the road

Pezzimenti Trenchless has recently expanded into new territories, tackling a microtunnelling project in the hard rocks of Hobart and installing pipe under one of the busiest roads in Adelaide.

Pezzimenti Trenchless was recently awarded a bore in Salamanca Place, Hobart, for Water Industry Solutions and Southern Water. The job involved a 36 m bore under Salamanca Place, Hobart’s oldest and most important tourist and cultural region.

A 225 mm PVC pipe was installed as part of the Salamanca Place pump station relocation works.

Ground conditions encountered were Jurassic Dolerite, a volcanic basalt type rock that covers over a third of Tasmania.

“They were probably the hardest rock conditions that we have taken on, but we still averaged 12 m per day using our 440 mm diameter basalt microtunnelling head,” said Pezzimenti Trenchless Director Joe Pezzimenti.

Mr Pezzimenti said the company looks forward to taking on the challenge of new projects in Tasmania in the future.

Pipe jacking in South Australia

The company was also successfully awarded a boring contract in South Australia for Camco Engineering and Construction and the City of West Torrens.

The bore involved pipe jacking an 800 mm Humes Jacking Pipe under one of Adelaide’s busiest thoroughfares, SouSouth Road, Mile End. To perform the installation in this highly sensitive area, the company utilised its 1,050 mm microtunnelling head.

The 30 m length bore was completed within the same week of arriving on-site.

“We see some huge potential with our microtunnelling system in South Australia, and look forward to working with authorities and contractors in the future,” said Mr Pezzimenti.
