Jon Brody Structural Engineers performed structural engineering for the build-out of the Officers’ Club Exhibition Hall within Presidio Building 50 (described by the Presidio Trust as "most likely the most historically significant building on the Presidio"). The project included development of a new structural steel lighting and equipment grid and its support by, and connections to, the existing building framing. As is usual on the Presidio, work was required to conform to Presidio Trust and National Park Service guidelines to protect the historic nature of the structure.
