Western Specialty Contractors – St. Louis Concrete Branch recently completed repairs to a concrete pedestrian bridge connecting Corporate Plaza in Chesterfield, MO, to a parking garage on the east side of the property. The 226,000-square-foot office building and bridge were constructed in 1989.
The building’s 109-foot-long pedestrian bridge, weathered and damaged from wear and tear, was constructed of precast double and single tees with a cast-in-place field topping. The bridge’s height ranged from 5 ft. to 30 ft. above the ground and had a canopy over it attached to a metal railing that was to remain in place for the duration of the project.
Property management firm Sansone Group hired Western and engineering firm Heideman Associates to facilitate the bridge repairs. Western used modular scaffolding to access the bridge and perform the following work:
- Concrete topping slab replacement
- Full-depth concrete repairs to the precast single and double tee panels
- Canopy post-base replacement
- Installation of expansion joints and joint sealants
- Application of a traffic coating membrane
The concrete was replaced in two phases to allow the pedestrian canopy to be supported half the time by existing post supports. Western completed the bridge repairs in three months, on schedule and within budget.
