Roads and Maritime Services (RMS) appointed North Projects as a specialist Infrastructure Estimator to develop the cost estimates for WestConnex motorway through the options and Concept Design development stage.
WestConnex motorway was originally developed as three separate connected projects, the M4-M5 Link, the M4 widening, and the M5 widening and tunnel duplication. The project had a tight timeframe, a large range of interfaces and was a key priority of both the Federal and State Governments.
During the concept design the final route was still being finalised. North was tasked with pricing multiple route alignments using cut and cover, Tunnel Boring machines and road headers to determine the most efficient construction methods in terms of time available equipment and impact of the works on the local communities.
The design development continued to evolve during the concept design stage. The project estimates were delivered by our project team in accordance with the client’s timelines. A weekly cycle of design change meetings was implemented by RMS with North updating the estimate in time for the next meeting. The overall project was market-tested during the concept phase by six consortia.
North’s cost plan estimate was given to the six consortia to provide RMS with industry feedback on the scope and agreement that the pricing was realistic and aligned with the market. The feedback confirmed concurrence with the proposed quantities and market pricing of the works.
