ProjectMonash Freeway Upgrade Stage 1

TSA Riley conducted independent reviews of the D&C tender documentation for Stage 1 of the AUD $400 million Monash Freeway Upgrade project – part of the larger AUD $5.5 billion Western Distributor program of works.

The Monash Freeway Upgrade addresses increasing congestion and traffic issues along one of the busiest stretches of road in Australia. As population and commuter numbers continue to grow, the existing infrastructure struggled to keep pace with rising demand, significantly delaying and frustrating Victorian motorists.

Stage 1 of the project alleviated these issues by expanding a large section of the freeway. More than 30 km of extra traffic lanes were added with the freeway being widened between East Link interchange and South Gippsland Freeway, and Clyde Road in Berwick. It also installed new ramp signals and upgraded on-ramp infrastructure to accommodate more cars.

As Independent Reviewer, TSA Riley reviewed and edited various components of the project’s ‘request for render’ documentation. This included scrutinising the project review committee report, the general conditions of D&C contract, tendering schedules, reference design drawings, and commercial and technical specifications.

Our team also provided technical advice to the VicRoads South-Eastern Projects team. This advice helped resolve design and constructability challenges, particularly surrounding the widening and strengthening of the twin 4-lane Princes Freeway bridges over the Pakenham Rail Line. Regular collaboration with structural bridge consultants WSP-Parsons Brinckerhoff led to the development of technical memos outlining a preferred strategy to minimise disruption to existing commuters on these heavily trafficked road bridges over one of Melbourne’s main rail corridors.
