Vibrations caused by the adjacent power plant that services the Longwood Medical Area posed unique design challenges. The sensitive equipment to be used in the new facility, as well as the consideration for out-patients receiving life-saving treatments, required that these vibrations not be felt in the building.

A structural system was developed that was entirely isolated from the surrounding soils. The slurry walls surrounding the below grade parking levels are supported by permanent tie-back anchors with an air gap provided between the walls and superstructure. Deep foundations elements, founded on bedrock, are isolated to minimize the propagation of vibrations into the structure. This project also includes a subterranean tunnel connecting the new Yawkey Center with the existing Dana Building providing patients with convenient and safe access from a valet- managed drop-off area to a new MRI center.

The first construction milestone, Simon Design’s slurry wall and foundation, is now complete and superstructure construction has begun. We are proud to be highlighted in Engineering News Record for our involvement: ‘Boston Slurry Wall Cuts Off Groundwater and Vibration’
