DC Streetcar – H Street, NE/Benning Road Line

This design-build project includes the construction of the western and eastern termini of the route for the streetcar, the overhead catenary that will deliver power to the streetcars, and the Car Barn at Benning Road-26th Street.  The first segment of the project includes laying out the track, utilities, retaining walls, and other associated site work.  The second segment of the project includes the construction of Car Barn building and maintenance yard.


DMY has been working on this project providing Quality Control construction materials testing and special inspection services which include field and laboratory testing for soil and aggregate, concrete and grout sampling and testing, and inspection of the bridge deck repair and drilled shafts for pole foundations.   DMY implemented its web-based electronic management and report delivery system – DMY Manager® to efficiently manage the project data.


Additionally, DMY prepared and is currently implementing a two level vibration monitoring program on this project for eleven (11) specified facilities along the project alignment.

Matthews Memorial Terrace

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.
