JOINT BASE ANDREWS, Md. -- Contractor utility men, Melvin Brooks, left, John Jones, center, and Adam Taylor, use a valve key to shut off the water pressure from a fire hydrant in the parking lot near the 316th Wing Headquarters, Bldg. 1535, June 19. Contracted under the 316th Civil Engineer Squadron, the workers performed a flow test on the fire hydrant to gauge the static pressure of water needed to support the fire protection system in the new BRAC headquarters facility, scheduled for completion March 2011.
