After 12 years of planning and construction, one of New York City's megaprojects is officially open. The Arup-led design features a 53-ft-dia glass oculus that rises 108 ft over an atrium and a stainless-steel "sky net." Measuring 144 ft x 140 ft at street level, the three-floor complex required nine construction contracts with the Metropolitan Transportation Authority Capital Construction division, with Parsons Brinckerhoff and Bovis Lend Lease LLC also managing.
