Maranoa Bridge Replacement


This $9.5m project for the Department of Transport and Main Roads (TMR) involved construction of a new bridge, demolition of the existing bridge and construction of approximately 400m of new roadworks approaches. The works were delivered via a Joint Venture with Albem.
Key scope of works:
Bridge Works

  • Subsurface Drainage
  • Protective Treatments
  • General Earthworks
  • Bridge Substructure
  • Cast-In-Place Piles
  • Prestressed Concrete Deck
    & Kerb Units, with Transverse Stressing

Road Works

  • Earthworks
  • Drainage Culverts
  • Subsurface Drainage
  • Protective Treatments
  • Unbound Pavements
  • Sprayed Bituminous Surfacing
  • Roadside Structures
  • Road Lighting
  • Planting Media

Notable aspects of the project: 

  • Coordinating logistics for remote works
  • Constructing a special piling platform across the Maranoa River bed, including installation of low flow culverts
  • A number of value engineering options were identified by SGQ, including the following adopted measures:
    • SGQ / Albem were very proactive in the ETI process to determine the most efficient design – including removal of pile-caps and substitution with larger piles that transitioned into columns, straight up into headstocks
    • By agreement, works commenced without finalised 100% documentation, to expedite works
