The Oregon Route 20 project resulted in the original design-build contractor being terminated from the project after bridge pier bents began shifting from construction activities in a landslide-prone area.
"Design-build is more of a risk on sites with extreme and challenging geotechnical issues," says Bill McGowan, who works for Watsonville, Calif.-based Granite Construction Co., the leader of the design-build joint venture called Yaquina River Constructors. "It may not be the best type of project for design-build."
