Microtunnelling contractor Rob Carr is continuing to make waves in the trenchless industry with the recent contract award for the Alkimos Main Sewer Section 1 construction.
The Alkimos Main Sewer Section 1 is a major capital works project for DevelopmentWA.
This will tie in with a 68m section of sewer beneath the rail corridor near Alkimos Station, completed as part of the Yanchep Rail Extension by METRONET.
The contract win for Rob Carr follows a competitive tender, which involved ongoing collaboration with several stakeholders for the major Alkimos Central Development.
This was a necessary and valuable part of the process to ensure a “best for project” outcome for all parties involved.
Rob Carr will self-perform the construction of 830m of DN1500 sewer and three access chambers.
The sewer will be constructed by two sections of micro tunnelling (157m and 306m), with the remainder constructed by open excavation.
The company has advised that over the next few months, other work on the project will include the construction of a 10m diameter in-situ concrete launch shaft some 9m deep, and a 12m deep receive shaft constructed using post and rail techniques.
