The International Spy Museum embarked upon construction of a new permanent home in Southwest Washington, DC, a few blocks from the National Mall. The landmark building will be a permanent cultural resource at L’Enfant Plaza in the nation’s capital when it is completed in fall 2018. At 140,000 square feet, the new Museum will provide more than double the floor space of the existing building, at 800 F Street NW, and will include new resources for educational programming, a lecture hall/theater, and multifunction 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 preconstruction surveys included 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 was conducted 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. These services were performed during demolition, pile driving, and site excavation activities as well as below grade construction.
