This project included the demolition of an existing two-span timber bridge and installation of a new, longer two-span precast concrete bridge using the Waeger modular precast system. The design of the centre pier featured FRP (Fiber Reinforced Polymer) for pier columns and the landing of the precast headstock at height. ACG eliminated in-situ concrete works, reduced working-at-heights risk, and saved time by piling directly to the headstock. This approach leveraged the extensive bridge construction experience of our project team.
To maintain continuous access for residents, a one-way contraflow bypass road was included in the project. This created challenges during the deck installation, as access was needed for the large crane and precast transport. However, with careful planning and consultation with our craneage subcontractor, we managed to set up the site and schedule the works with minimal additional delays to road users.
This project followed a series of similar installations using the same modular precast bridge system. Despite some unique challenges, the team’s extensive background in bridge construction ensured a smooth timeline with minimal disruption to local stakeholders.
The deconstructed timber bridge was backloaded to a local salvage yard for recycling and repurposing.
