Matthews Memorial Terrace is located on a 2.2-acre urban site in the Anacostia region of Southeast Washington, DC. The project consisted of the construction of a 99-unit five-story residential building over a partially below grade parking garage, five retaining walls, and associated site utilities and pavements. The residential building has an approximate total gross floor area of 111,200 SF and is supported by a shallow foundation system consisting of spread and continuous footings over Geopiers. The new building is used to house senior citizens and low-income residents. DMY’s engineer performed the geotechnical investigation for this project. DMY also provided complete construction materials testing and special inspection services. The project was completed on time and within budget.
During construction, the adjacent property owners raised concern of the impacts of construction vibrations on the adjacent structures. DMY promptly provided the client a vibration monitoring program and implemented immediately upon authorization. The vibration monitoring data showed the construction vibration level was well below the damaging threshold and protect the client from potential claims.
