TSA was contracted through Transurban to carry out independent reviews of the D&C tender documentation being prepared for the $400 million Monash Freeway Upgrade project (which forms part of the over-arching $5.5 billion Western Distributor program of works).
The scope of works on the Monash Freeway Upgrade project includes;
- Approximately 30 kilometres of additional traffic lanes, all added within the existing road reserve.
- Widening from 4 to 5 lanes in each direction between EastLink interchange & South Gippsland Freeway.
- Widening from 2 to 3 lanes in each direction from South Gippsland Freeway to Clyde Road in Berwick.
- New and upgraded ramp signals and extra space for more cars on-ramps from Chadstone to Pakenham.
TSA’s Independent Reviewer role included detailed review and editing of RFT documentation including;
- Project Review Committee (PRC) report.
- General Conditions of (D&C) Contract (GCC).
- Request For Tender (RFT) schedules.
- Reference Design Drawings.
- Commercial and Technical Specifications.
In addition, TSA provided Technical Advice to the VicRoads South-Eastern Projects team in resolving design and constructability issues for widening and strengthening twin 4-lane Princes Freeway bridges over the Pakenham Rail Line as required on this project. This involved regular liaison with structural bridge consultants WSP-Parsons Brinckerhoff, to produce technical memos that mapped a preferred strategy for minimising disruption to existing commuters on these very heavily trafficked road bridges over one of Melbourne’s key live operational rail corridors.
