2M Street Apartments, NE DC
The 2 M Street Apartments consists of a 12-story structure providing 314-units of housing and is partially funded by the DC government. Steele Foundation crews were recently finishing the underpinning and sheeting operations at the estimated $82 million project. The project required underpinning of two adjacent masonry structures and support of excavations up to 20 feet in depth. Layers of wet, loose sand encountered several feet above the proposed excavation subgrade required the use of specialty grouting to allow for the installation of underpinning piers.
