A project of the Federal Recovery Act of 2009, the roof at the J. L. McMillan Federal Building and U.S.

A project of the Federal Recovery Act of 2009, the roof at the J. L. McMillan Federal Building and U.S. Courthouse joins the rankings of one of the largest green roofs in the Southeast United States to date, and it may be the largest in South Carolina. An extensive green roof system was selected due to the load constraints of the existing structure. Roughly 51,000 plugs from Emory Knoll Farms including species of Sedums, Delosperma, Talinum, and Allium were planted in 329 tons of lightweight Stalite-PermaTill growing medium at a 4”depth. Staging this project was especially challenging because the courthouse remained open during its construction. The crane was frequently moved to accommodate employee parking and a few night shifts were necessary to access one side of the building. Lifting 220 crane bags of growing media to a 5-story roof could have been a logistical nightmare, but the team at Living Roofs, Inc. executed the entire installation with no serious complications. http://www.greenroofs.com/projects/
