Park Square Pedway Bridge Restoration
Park Square’s pedway bridge was constructed circa 1975 to provide pedestrian access from the main lobby of Park Square Apartments to Bellamy Hill Road.
RJC’s structural condition evaluation of the pedway bridge structure revealed severe corrosion of the metal deck, in addition to corrosion of supporting structural steel joists and trusses.
After evaluating various methodologies, and considering the client’s desire for long-term rehabilitation of the pedway bridge, it was recommended the entire composite concrete topping and metal deck assembly be removed and replaced.
RJC incorporated numerous measures to maximize service life and future durability, including corrosion-inhibiting concrete admixtures and cementing materials, heavier-gage galvanized deck coatings, application of protective coatings to metal decking and structural steel members, improved drainage systems and surface slopes, and installation of a new waterproof membrane and expansion joints.
Localized repairs included reinforcement of support connections for structural steel support members and precast wall panels, concrete delamination repairs, and replacement of deteriorated concrete upstand walls.The project was completed in two phases in order to maintain pedestrian access.
The work was performed within the Owner’s schedule and under budget, permitting inclusion of additional work.
