Clark is constructing an 11-story cast-in-place concrete office building as the third and final phase of the Sentinel Square development in Washington, DC’s NoMa neighborhood.

The 728,000-square-foot structure will be the largest of the Sentinel Square structures, and will include office space, common amenity areas, a penthouse, and three levels of below-grade parking. The precast façade will feature blast-resistant ribbon windows.

The project is designed to achieve LEED® Silver certification.

Metro Earthworks, Clark Foundations, and Clark Concrete are part of the project team and will perform excavation, support of excavation, and cast-in-place concrete, respectively.
