The new Birmingham Social Security Administration (SSA) Center, Birmingham, Ala., is a $100 million facility built through a 20-year lease agreement between Opus South Corp., Atlanta, and the U.S. General Services Administration. The 587,000-square-foot building was built to replace the existing building that had housed the SSA since the 1970s.
The building, which has an eight-story tower rising above its second story, required installation of several roof systems. In November 2005, Opus South contacted Chris Pinkston, vice president of Construction Services, Atlanta, a Tecta America company, to discuss installation of a vegetative roof system.
A joint effort
Opus South wanted 83,000 square feet—or nearly 2 acres—of vegetative roofing materials installed on the building's exposed second-floor rooftop, as well as a polymer-modified bitumen system installed on the eighth-floor rooftop.
