Building Envelope Evaluation and Restoration
General Services Administration
Nine story building, 27,500 square feet of roofing
- Highly sensitive Federal Courthouse Building administered by GSA.
- Assessment of building envelope required due to lack of current information and suspect roof conditions.
- Remedial recommendations were necessary to enable funding requisition process.
Conley Group, through our contract with General Services Administration Southeast Region, conducted a comprehensive evaluation of the building envelope systems, roofs and walls at the Federal Building and Courthouse in Nashville, Tennessee. The visual review assessed conditions, documented observations, reviewed leak histories and quantified severity of defects and conditions.
Roofing systems were asphalt built-up on sloped light weight concrete over structural concrete decking on four roof areas. Exterior walls were non-load bearing pre-cast panels on concrete block and metal studs. Finished aluminum windows are “punched” into the pre-cast panels. The first level differs with granite panels instead of pre-cast. Construction was circa 1975.
Field investigation identified conditions contributing to on-going moisture infiltration from existing windows where joint sealants and gaskets failure was apparent. Although no apparent leaks were identified roof system conditions were indicative that the roof life was beyond expectations with replacement as the only feasible option.
Conley Group developed a comprehensive report to document findings including photos and CAD Drawings. Detailed recommendations along with a comprehensive cost estimate associated with the recommended remedial actions for the roof replacement and wall window system repairs were developed.
Comprehensive construction documents were developed for public sector bidding. Conley Group provided administrative and site inspection services during construction as owners representative.
