CRR has gone through a number of iterations and false starts including BaT prior to our engagement on the most recent Business Case and Approvals process. The team was able to develop innovative solutions with regard both the form of the project (shorter tunnel, modified routes, staged stabling solutions) and delivery strategy including the separation of CRR into three projects: the greenfield tunnelling works, brownfield rail works and ETCS signalling. This innovative structuring and procurement approach enabled CRR to be successfully procured and it is currently being constructed.
This large bypass of Toowoomba was largely driven to improve access to Toowoomba, improve safety and remove oversize vehicles from travelling through the city. Through the interactive engagement with bidders the tunnel was replaced with a large cut through the top of the range that allowed all Dangerous Goods Vehicles to use the bypass (rather than still sending them through the City of Toowoomba) while reducing the OPEX for the project which provided large Whole of Life and sustainability benefits.
Airport Link was procured with the Northern Busway and Airport Roundabout Upgrade D&C projects and was Australia’s largest road project at the time. The scale, complexity and technical challenges resulted in the project having significant community impacts. Throughout the procurement process innovation was encouraged and it led to numerous changes that included moving the largely above ground Kedron interchange underground improving community amenity, reducing the size of ventilation outlets on the project, integrating the Northern Busway more efficiently with the toll road and simplifying the congested Airport Roundabout.
New Gold Coast Stations program of works is constructing three new stations at Pimpama, Hope Island and Merrimac. The team worked with the CRRDA to accelerate the program by amending the delivery strategy, updating the contract documentation and running three interactive tendering processes simultaneously. The contracting strategy for each station was developed to respond to the varied challenges that were specific to each location. We worked successfully with numerous stakeholders including QR, TMR, CoGC and TransLink to achieve all three procurements in a compressed 15-month time frame.
The Northern Busway was constructed as a predominately underground solution that needed to have open air stations to minimise OPEX costs. This was easily resolved in Kedron by constructing the station at surface. Lutwyche Station presented greater challenges with the tunnel connecting Kedron to Truro Street. Throughout the interactive tendering process with BrisConnections we were able to work with the successful consortia to develop a station that was open air and was sited under Lutwyche Road. This solution provided the OPEX savings while maintaining the Busway underground.
