Cedar Creek bridge over Mathew Creek Road at Thirlmere connects an important road link in the local area. Antoun was engaged to undertake the replacement of the bridge crossing and provide an important freight route supporting local industry. The aim of the bridge reconstruction was also to increase capacity of the road for future development
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 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, and 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.
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.
