Supply of 700 metres of DN300 BOSSPIPE CCGRP – 650m Jacking Pipe and 50m open trench Pipe

In 2017, CRE Excavations were awarded the contract to construct the Trunk Sewer which would service the residential development at Chesterfield Park in Warragul, Victoria.
This sewer, designed by Beveridge Williams, comprised of 700 metres of DN300 sewer pipe, to be installed at depths ranging from m to 8.5m. With the majority deeper than 7 metres. Given the complexity of open trench this pipe at those depths, it was proven to be safer, timelier and more cost effective to install the pipe via trenchless methods.
CRE engaged experienced micro tunnelling contractors Edge Underground to handle the trenchless section of the installation, whilst self-performing the open trench section.
It made sense for CRE to go for the trenchless option, given the design depths. The size of the open trenches, the requirements of shields, the amount of backfill required and the safety risk were all eliminated by choosing the micro tunnelling with the BOSSPIPE CCGRP Jacking Pipe.
