Case Study: National Audio-Visual Conservation Center Steep-Slope Roof Waterproofing
Presented by: Corey O'Connor
The National Audio-Visual Conservation Center was originally constructed in 1969 by the United States Federal Reserve to serve as a bunker during the Cold War, with the purpose of housing enough U.S. currency to replenish a portion of the country in the event of nuclear war. In 2007, the bunker underwent a 250 million dollar rehabilitation and was transformed into a repository for the Library of Congress’ 6.3 million plus pieces of movie, television and sound recordings.
During this lecture, participants will hear from Corey O’Connor, who represented the manufacturer of the materials used by the team that was tasked with designing and implementing a vegetative roof assembly that successfully addressed complexities associated with the slope and overburden of the existing roof system. The program will include details on the project background, a pictorial walkthrough of the project as it progressed, the design and solution of the roof assembly, and an interactive Q&A.
Featured Speaker Biography:
