The Pacific Motorway (M1) - Pimpama (Exit 49) Interchange Upgrade was delivered to increase capacity, improve network efficiency, and enhance safety for all road users.
BIM one delivered the utilities engineering scope for the M1 Pimpama Interchange Upgrade, a major project aimed at increasing capacity, improving traffic efficiency, and enhancing safety. The upgrade involved collapsing the two roundabouts into new signalised intersections, significant upgrades to the associated local service roads, and installation of a new overpass bridge.
The team was responsible for the coordination and management of PUP site investigations, the detailed conflict assessment, development of relocation / protective treatments, liaison with utility authorities and negotiation of technical solutions with authority representatives.
Through early design collaboration and strategic refinements, BIM one reduced utility impacts identified during the Business Case phase - achieving approximately $4 million in relocation cost savings while maintaining technical integrity and delivery certainty.
Acting as PUP Lead, Michael led authority liaison, utility investigations, detailed conflict assessments, and the development of relocation and protective treatment strategies. The team managed all site investigations - including geotechnical, pavement, ITS, ecological, noise, traffic and utility surveys, and coordinated planning, programming, traffic control, and on-site delivery.Through close collaboration with the broader highways and civil design team, BIM one refined geometric layouts and drainage solutions to minimise utility impacts, reducing relocation costs by approximately $4 million compared to the Business Case.
