Mission Ridge Delivered to Owner Early, On Budget

CHANTILLY, Va. – Continuing the company’s mission to provide excellent client service and become a leader in green building, Clark Construction Group, LLC, completed Mission Ridge one month ahead of schedule, on budget, and the project has been submitted for LEED® certification.

The $40 million project consists of two five-story, Class-A office buildings in the Westfields Development in Chantilly, Va. The two 150,000 square-foot core and shell office buildings feature a precast and ribbon window façade with a three-story vertical fin at the entrance canopies. Terrazzo flooring, wood veneer and decorative metal ceilings highlight the main lobbies. The project also included the development of a 17-acre site primarily utilized for on-site parking.

The project team was accepted into the United States Green Building Council’s pilot program for LEED Core & Shell buildings and project goals included efforts to ensure indoor environmental quality as well as efficient management of water, energy, and material resources.

Sustainable site efforts include reduced site disturbance, stormwater management, and reduction in light pollution. To reduce water consumption by 40 percent, dual flush valves, low-flow showerheads and faucets were installed in each bathroom. Efficient urinals were installed in each men’s restroom. No permanent irrigation system will be installed on site, which will further contribute to the project’s reduction in potable water consumption.

Contract specifications called for the use of low-emitting paints, coatings, adhesives, and materials with high recycled content. Post-consumer content accounted for 19 percent of total material cost; post-industrial content accounted for 11 percent.

Clark set a goal of diverting 50 percent of construction waste from landfills. At project’s end, 88 percent of the 1,200 tons of construction waste generated was recycled or otherwise diverted from a landfill.

Clark, the design team, and the owner worked together to overcome many schedule and engineering obstacles in order to meet the owner’s requirements. Necessary changes to the blast design criteria required expedited engineering solutions and overtime installation. Sliding production and material delivery dates necessitated increased coordination and management.

The successful delivery of Mission Ridge directly resulted from strong collaboration between project owner The Carlyle Group, Development Managers Jones Lang LaSalle / Ardent Management, Clark, and project partners including SmithGroup of Washington, D.C., architect; Cagley & Associates of Rockville, Md., structural engineer; Girard Engineering, PC, of McLean, Va., MEP engineer; and Sustainable Design of Silver Spring, Md., LEED consultant.
