3D scanning assists in Hoover Dam bypass project.

In late 2001, AMEC, an engineering services and consulting company of Phoenix, contracted with DEI Professional Services, an engineering and surveying consulting firm in Phoenix, for a monumental 3D geological mapping of the Hoover Dam area for the massive $198 million bypass project. The new crossing will feature a four-lane divided highway and a 1,900 ft bridge that will bypass the narrow and heavily congested U.S. Highway 93 crossing at the Hoover Dam. AMEC is also charged with developing approach bridges and roadways in Nevada and Arizona, a tunnel in Nevada, other interchanges, and several wildlife underpasses and overpasses. DEI Professional Services provided detailed digital terrain models of the rough terrain at the point where a proposed bridge will cross the Colorado River.
