Access to the 13-story Hampton Inn site in Washington D.C., across the street from Washington Nationals Park, was limited as construction took place in the middle of baseball season. Belfast Valley Concrete used shifting schedules to pour each deck on a five-day cycle, and during each pour started framing the next pour chasing one level below.

Accustomed to working the Washington D.C. hub, Belfast Valley Concrete knows how to choreograph around scheduling and logistical constraints. One such challenge was the Exchange at Potomac Yards, a 1.9 million-square-foot multiuse complex wedged between Alexandria and Arlington, Va. The crew installed ramps and roads to facilitate concrete pumping and tailgating of mixers. To avoid interrupting production by removing the ramp and roads, slab-on-grade was poured first clockwise to the ramp, then counterclockwise during removal, just in time to continue framing the deck above it. The crew placed 22,000 cubic yards of concrete in 25 weeks, three weeks ahead of schedule.
