Mortenson Awarded $48.9 Million Design-Build Contract at Fort Sill

Fort Sill, OK — The Fort Worth District of the U.S. Army Corps of Engineers has awarded Mortenson a $48.9 million design-build contract for a 226,143 square foot Unaccompanied Enlisted Personnel Housing (UEPH) Barracks complex at Fort Sill, Oklahoma. The complex consists of seven barracks units, each ranging in size from 31,000 to 34,000 square feet. The St. Paul office of HDR Architects is Mortenson’s design partner for this project. This is Mortenson’s first project at Fort Sill, home to several well-known and respected U.S. Army artillery units including the 31st Air Defense Artillery Brigade and the 75th and 214th Fires Brigades.

The new project involves the design and construction of an apartment-style barracks facility for single enlisted personnel. Each new barracks will provide living units for approximately 90 people. The total UEPH complex will provide space for 620 soldiers. Each living unit will have two bedrooms with shared bathroom and kitchen. Two of the buildings will have activity rooms and formal lobby areas. All buildings will have centralized laundry/tornado shelters, janitor’s closets, and recyclables storage. The complex will use closed-loop geothermal systems for heating and cooling, which will provide a significant energy usage savings. Each barracks will have its own geothermal ground loop system, vertical wells and pumps, located adjacent to the building. Built on a concrete ribbed mat slab, each UEPH structure will consist of steel stud bearing walls and formed concrete floor decks. The terra cotta colored standing seam metal roof and stone-accented tan brick walls will be compatible with the existing architecture at Fort Sill. The high tower and canopy will provide an architectural focal point at the end of each building, emphasizing the entrance and visually tying all seven barracks together in a dramatic progression of structures along the length of the site. The UEPH Barracks will be designed to comply with Department of Defense Anti-Terrorism/Force Protection (ATFP) requirements and to achieve LEED Silver certification.

Design began in May and construction will begin in July. Completion is scheduled for December of 2011.
