Scope Of Works
Our project scope included the construction of The Bonds Creek Carrier Section 2 (Open-Cut sections), lead in pipe sections (Open-cut), adjoining Vent shafts, associated maintenance holes and Entry and Exit Bore-Shafts & surrounding hard-standing for the micro tunnelling contractor.
1.9km of gravity sewer mains ranging in size between DN225 and DN525 with depths ranging between 2m and 6m deep.
As well as the pipeline, Killard was awarded the construction of 18 sewer manholes and the connection to the existing network.
Outcome / Key Features
Laying pipe in water charged ground up to 5m deep demonstrated our expertise and commitment to prioritize WH&S and Environmental procedures to meet legislative requirements as well as worker safety. It also shows our understanding of complex construction issues including the use of precast – HDPE lined manhole segments as well as our ability to communicate and collaborate with contractors to deliver Sydney Water projects solution for the client.
Works completed on time and within budget, works carried out within private properties where heavy community engagement was required to ensure a positive outcome for all. High emphasis on planning and notifications was given to ensure works were carried out in line with agreed timeframes between client and property owners.
Good management of resources on site to ensure scope overlaps (excavation and shoring of launch and receive shafts) were completed on time to ensure no delays for the micro tunnelling subcontractor.
