Coalinga State Hospital

Project overview

In 2002, the state of California hired Vanir to oversee the construction of its new acute care psychiatric hospital, Coalinga State Hospital. At the time, this was the single largest general building construction contract. The facility provides housing and treatment for 1,500 patients — offenders who are committed for health treatment under California’s Sexually Violent Predator Act.

As a result of our change order management through monitoring daily work activities and verifying all material invoices, the change order savings was approximately $3 million.

The hospital is widely considered to be one of the most successful projects undertaken by the State’s project management branch of the Department of General Services Real Estate Services division.

Overcoming a challenge with location

The site selection was the earliest challenge faced. No community wanted this facility in their “backyard.” The architect team needed to create a design that could be built on any site. Vanir assisted with educating the community in understanding the benefits of this type of facility.
