Nerang 8 Laning Project

The PSC included support in design and project management elements. The construction component of the contract involved several separate contracts including:

 

 

  • Public Utility Plant adjustments totalling $5M.
  • Early bridge construction contracts totalling $7M.
  • Package 6 (Value $54M) construction contract involving urban style construction including cut and cover tunnel, two Freeway Overbridges, major excavation involving contiguous  piling. and retaining walls, flexible pavements, asphalt pavements, and enormously complex traffic staging issues.
  • Package 5 construction contract (Value $34M) involving major “semi-rural style” roadwork construction on flexible pavements with asphalt base layers and surfacing.
  • Miscellaneous contracts including contracts with Main Roads, RTCS.

 

The project was extremely complex and proved a difficult administration project due mainly to some rather poorly presented plans.  The Package 6 component was ultimately completed under Alliance principles due to the extensive disruptions caused by the lack of suitable plans.
The role of Professional Engineering Service Pty Ltd was to provide a Contract Superintendent (Allan Kennedy), and ultimately up to 9 field and administrative staff including Superintendent's Representatives, field Surveillance Officers for both road and bridge works, quality assurance representatives and office administration personnel.
The original PSC contract was a Lump Sum, however the massive difference in numbers of staff required at commencement, compared to that eventually required resulted in a final consultancy fee of $3.8M (3.8%), under extremely adverse contractual circumstances.
