The scope of works included

  • Initial works for the project included traffic control, demolition of existing bridge structure, site clearing, and test coring for precast piling.
  • To install precast piles, Antoun excavated and diverted of the existing waterway using temporary pipe diversions and localised dewatering prior to commencing earthworks.
  • The construction component of the project involved a mass block retaining wall, precast piles, concrete headstocks to enable in-situ approach slab to be constructed in a timely manner.
  • Finishing works included flexible road pavement, storm water installation, kerb and gutter, line marking and signage.

The results

Antoun discovered the discrepancies in the initial design indicating that foundation piles were to be installed through an existing gas main service. This triggered a re-design in conjunction with approvals and supervision by Jemena (Gas Assett Owners). This ensured that a major incident was avoided ensuring a successful outcome for all stake holders.
