Project Overview
A series of targeted repairs and structural enhancements for Central Coast Council to improve the integrity, safety and longevity of the Forth River Bridge.
A detailed structural inspection by an experienced structural engineer guided the repair strategy.
Delaminated concrete and defective reinforcement in the crossheads, piers and abutments were repaired with high-strength grout, and cracks were sealed by epoxy injection to restore structural cohesion. Deck joints were replaced and repaired using a joint sealing method to maintain water resistance.
Rock pitching around the abutments and the kerbs were restored to match the original structure. A traffic management plan and temporary guardrails maintained pedestrian access and traffic flow, and early procurement avoided material delays.
Key figures: Concrete patch repairs, epoxy crack injection, deck joint replacement, rock pitching and kerb rectification.
