Gateway Upgrade North

Location: 
QLD
Total Project Value: 
>$1000M

This project involved an upgrade of the northern section of the Gateway Motorway between Nudgee Road and the Bruce Highway. The upgrade was designed to provide operational improvements to assist safety and relieve major congestion hotspots, and target transport planning in areas where the corridor was under pressure from an adjacent development. 

Queensland Transport and Main Roads (TMR) needed to consider a range of delivery strategies, project staging, project scoping options and project service requirements to determine the best Value for Money (VFM) option and, to this effect, identified:

  • Option 1: Upgrade Motorway with Alignment Improvements (“On-Line” Option) including widening the existing road from four lanes to six, with allowance for further widening to eight lanes in the future
  • Option 2: Road Beside Road (“Offline” Option) including construction of a new road

MIEngineers was engaged to provide independent first principles options analysis estimates to form the basis of a preliminary Cost Estimate Report to be considered by the Queensland Government.  

The cost estimates included P50 and P90 risk adjusted project cost estimates (Project Budget) for all service options, a construction schedule and a Project Estimate Report 

MIEngineers’ understanding of the TMR Estimate Work Breakdown Structure, large motorway projects and risks, meant that the estimate was completed to the client’s requirements. In order to meet the tight deadline for the estimates, a detailed programme was developed and monitored throughout the estimate works.
