Case Study: National Audio-Visual Conservation Center Steep-Slope Roof Waterproofing

Presented by: Corey O'Connor​

​

Description:

​

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.
