Notable Aspects

  • The contract was won through an ETI (Early Tenderer Involvement) tender process
  • Coordination of logistics for remote works
  • Construction of a piling-rig access platform across the Maranoa River bed, including installation of low flow culverts
  • Value engineering options identified by the JV included 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
