California's transport authority awards first ever design and build contract

Caltrans has awarded its first ever design and build contract to Granite Construction, for the $37M (£23M) reconstruction of State Highway 99.

The project could be completed up to a year ahead of schedule by using design and build.

“Caltrans is taking advantage of innovative solutions like design-build to be more efficient and get the most out of taxpayer’s investments in our transportation system,” said Caltrans acting director Malcolm Dougherty.

Design and build is currently being used in 32 other US states. Caltrans obtained design and build authority in February 2009 with the passage of Senate Bill 4 (second extraordinary session). The legislation established a demonstration program, which allows Caltrans to carry out 10 design and build projects.

The project will repair 6km of Highway 99 in both directions in Madera County.

Construction is planned to begin in mid-July 2011 and is estimated for completion by December 2012.
