“It is fortunate that we embarked on this expansion program at Dulles in recent years in light of the increase in passengers we see each day and the expected dramatic growth by the end of the summer,” said James E. Bennett, MWAA’s Chief Executive Officer. “It is very important that we continue to invest in our airport facilities to keep our region well-served by the aviation industry.”
Clark/Shea’s contract consists of three phases. The 1,880 linear feet of NATM tunnel excavation will occur in the first phase. Atkinson Construction, Clark’s heavy construction subsidiary, will participate in the tunneling portion of the project. In addition to structural demolition, the team will pour 21,650 cubic yards of structural concrete, oversee utility relocations, concrete pavement demolition and install an MEP system for the tunnels. During the second phase, the team will excavate and provide support for the West APM Station at Concourse B.
