Risky Business
Labor, clients, project conditions and information flow are all potential risks that small design firms face when deciding to agree to a fixed price. If you're in charge of...

Cap of Concrete
The roof of a new $84 million arena in New Orleans was built using techniques usually seen in tied-arch concrete bridges. The concrete components of the roof carry the large compression...

Up against the Wall (available in Geoenvironmental special issue only)
A tight site in Portland, Oregon, bounded by existing roads and a light rail line and bordered by underground utilities, required project engineers to develop a new type of shoring wall...

Energy Unleashed
