DPR Construction Mid-Atlantic Headquarters

As part of the design team led by SmithGroup, McMullan provided structural engineering, construction documents, and construction administration services for the 20,000 SF renovation of an existing, long-vacant building in which DPR chose to house its Mid-Atlantic headquarters. The building comprised steel framing with a load-bearing exterior brick masonry wall supporting steel roof joists and steel lintels over the windows and openings. Its second floor featured steel joists and steel beams with a concrete slab on form deck. It also had a basement wall on its north side only.

DPR’s facility program focused on four key goals: to create an “Office of the Future” that invigorates their people; to be environmentally responsible in the way they do business by pursuing Net Zero Energy, LEED certification and the WELL Building standard; to make smart, data-driven decisions; and create a living laboratory that can showcase technologies, products and systems.

McMullan’s scope involved designing support and preparing construction documents for the roof-mounted solar panels, installation of a new canopy at the north entrance, a new entrance sign, and installation of a hung NanaWall from the roof structure. McMullan also investigated the existing structure for a new state-of-the-art mechanical room housed on the second floor which is atypical to where mechanical rooms are traditionally situated in buildings. In addition, we analyzed existing framing and prepared construction documents for dunnage and a new garage door based on the client’s desired layout.
