The fatal collapse of an under-construction pedestrian bridge and—more than 12 hours later— the overnight crash of another nearby span at a $49-million community-college project in Raleigh, N.C., have contractors, engineers and state safety officials stumped for a cause of the two failures at the Wake Technical Community College Building F project.
On Nov. 13, around 10:30 a.m., workers with Skanska USA Building's subcontractor, Central Concrete of North Carolina, were placing concrete on the deck of a bridge, connecting Building F with a nearby building, when it collapsed.
