The International Spy Museum embarked upon construction of a new permanent home in southwest Washington, DC, a few blocks from the National Mall. Completed in 2018, the landmark building is a permanent cultural resource at L’Enfant Plaza. At 140,000 square feet, the new Museum provides more than double the floor space of the previous home and includes new resources for educational programming, a lecture hall/theater, and multi-function event space with sweeping views of DC.

Over the course of a nine month period F&R provided pre-construction surveys and vibration monitoring services during construction activities as the potential impact of adjacent construction on occupied buildings, sensitive facades, and historic structures were a concern to the owner and construction team.

F&R’s Monitoring Team specifically provided:

Pre-construction surveys consisting of photographic and videographic record of the existing garage levels below the proposed structure, an adjacent Metro station, office spaces, hardscapes and above ground
utility systems.

Vibration monitoring in various locations adjacent to and below the proposed site to supplement findings of the pre-construction survey and help quantify potential vibrations associated with adjacent construction activities. Monitoring was conducted during demolition, pile driving, and site excavation activities as well as below grade construction.
