Construction has begun on the new north terminal at Detroit Metropolitan Wayne County Airport. San Francisco-based Gensler is architect/engineer on $300-million project. The 26-gate, 824,000-sq-ft terminal will service international, domestic and charter flights. “One of the first new terminal designs after 9/11 includes...100% screened baggage,” says Bill Hartman, Gensler design principal and managing director. The linear, bi-level glass and steel structure complements the architecture of the four-year-old McNamara Terminal, he says. Its curbside facade, a 660-ft-long horizontal glass curtain wall, serves as a high-ceilinged foyer to allow natural light into the ticketing, baggage claim, and security screening areas. Walbridge/Barton Malow is construction manager at-risk. The building’s expected opening is summer 2008.
