Sam M. Gibbons U.S. Courthouse
Design/Build Curtainwall Investigation and Repair
Tampa, Florida

The Sam M. Gibbons U.S. Courthouse is a 390-foot tall, 17-story, 240,000 sq. ft. high rise office tower located in downtown Tampa, Florida. The building suffered from significant water intrusion through multiple facade systems since the building was constructed in the 1990’s. In conjunction with our design/build partner, American Restoration, Inc. (ARI), Facility Engineering Associates, P.C. (FEA) initially performed an in-depth evaluation of the facade systems to identify the sources of the water intrusion and to establish possible solutions to the identified issues.

The evaluation included a series of intrusive openings of the facade to establish potential deficiencies that would allow water infiltration and to document the as-built conditions. Confirmatory water testing was conducted to verify the sources of infiltration. Multiple sources were identified requiring unique solutions for each system.

Based on the investigation phase, FEA developed a repair protocol for our design/build partner to implement. ARI completed mock-ups of each of the repair procedures and confirmatory water testing was performed to verify successful remediation of the infiltration.

Based on allowable contract budgets, Phase I of the construction included floors 16 and 17 including the east mechanical penthouse. During the construction, FEA performed construction monitoring activities including periodic site inspections, development of remedial details for unique, uncovered hidden conditions, and completion of punchlist inspections. Since the first phase of the project was completed in August 2009, the building has not experienced any further water infiltration issues at the locations associated with phase 1. Phase 2 addressed the remainder of the building envelope including all roofs.
