Washington Dulles International Airport was one of the most modern airports in the world when it opened in 1962. During the years, the number of passengers increased and the airport has grown. In 2000, the Metropolitan Washington Airport Authority (MWAA) implemented its most ambitious capital construction campaign to date. Clark/Shea, a joint venture of Clark Construction Group, LLC of Bethesda, Md. (www.clarkconstruction.com) and J.F. Shea Company, Inc. of Walnut, Calif. (www.jfshea.com) has been selected to work on a portion of this redevelopment effort as a result of the competitive solicitation process. The $78.5 million West Domestic Tunnel Corridor project will support an automated airport train system, which will run underground and connect the main terminal with the midfield concourses and replace the mobile lounges currently in use.
“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. In the final phase, an emergency radio system will be installed in the tunnels and adjacent structures. The entire project will be completed by Summer 2007.
HNTB of Arlington, Va. is serving as the structural and civil engineer for the first phase. Additional team members for this phase include Hatch Mott MacDonald of Rockville, Md., tunneling designer; Wisnewski Blair and Associates, Ltd. of Alexandria, Va., architect; and Diversified Engineering, Inc. of St. Augustine, Fla., MEP engineer; and Burns Engineering, Inc. of McLean, Va., electrical engineer. Michael Baker Jr. Inc. of Alexandria, Va. is serving as the structural and civil engineer on the second phase of the contract. Additional team members for phase two include Schnabel Engineering of West Chester, Pa., support of excavation; Burns Engineering, Inc. of McLean, Va., MEP engineer; and HOK of Washington, D.C., architect. Big Sky, Inc. of Manassas, Va. is providing the emergency radio design for the last phase.
