Structural repair of ten (10) Bridges, Wisconsin, USA
Project: Structural repair of ten (10) Bridges
Location: Wisconsin, USA
Client: Wisconsin DOT
Contract Duration: 24 days
Scope of Works:
• Structural repair and treatment of deteriorated concrete members
Project Description:
Like most concrete bridges around the country, the pier and pier caps are exposed to very harsh conditions, especially in the northern states. Wisconsin DOT, Southwest region, has an annual program of selecting 10-12 bridges to be repaired during the summer months. These structures suffer from deteriorated concrete with exposed reinforcing steel and sometimes exposed pre-stressing strands.
The regional engineer uses discretionary funds and awards a repair contract every year. The repairs consist of removing all loose concrete, applying a corrosion inhibitor, restoring the section using a concrete mortar and applying two layers of glass fiber composite over the repair areas.
The process got done very quickly from the decision time to repair until the work is completed. In this case it was 24 days for 10 bridges.
