DC DGS Headquarters

The DC Department of General Services has a new headquarters facility as part of the Northeast Heights mixed-use development in Northeast DC. The 258,000 sf facility features four levels of office space, ground floor retail, a penthouse, a rooftop terrace, and a below grade parking level.

The bay spacing of the building varies from a typical 30’ x 30’ in the garage to up to 41’-6” x 30’ at the office levels. This was achieved by eliminating some columns in strategic locations to avoid using transfer girders. The precast façade required coordination with the post-tensioned concrete floor framing because of the large forces exerted by the typically 8” thick x 30’ long concrete panels.

As tenant requirements became known during construction, modifications to the building were made to accommodate specific demands that differed from the office loading that was originally designed. One of these modifications included altering the slab design to accommodate a multi-level slab opening for a hung feature stair.
