A project to rescue a dilapidated, 178-year-old house on the edge of Washington, D.C.'s National Mall won a $1-million grant on Dec. 9 from American Express.The lockkeeper's house served a freight canal, located near where the Washington Monument is now. Canals formed an inland freight transportation system, which was eclipsed by railroads in the 1870s.Boarded up since the 1970s, the house will be moved back from the road and undergo extensive interior and exterior restoration.

WSP Group If all goes according to plan, architect Frank Gehry's second high-rise building, a 305-meter-tall skyscraper currently entering its schematic design phase, would become, at 305 meters, Canada's tallest building. The planned residential building, which received Toronto City Council approval in July, is expected to be under construction in 2016 and take four and a half

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

The 104-story tower—designed by architect Skidmore, Owings & Merrill, with structural engineer WSP Cantor Seinuk and mechanical engineer Jaros Baum & Bolles after an early collaboration with Studio Daniel Libeskind—has redundant and beefed-up structural and mechanical systems, and the air-supply

Called Formosa, the house, which sits on the ground, has a concrete tub-like basement foundation that floats during floods.The house is designed by BACA Architects with structural engineer Techniker and hydrological engineer HR Wallingfords, to handle up to 2.5 m
