William J. Carroll Government Center

Vacaville, CA

A competitive Design-Build project, the William J. Carroll Government Center is a true example of cost efficiency delivered with high design. Utilizing tilt-up concrete construction integrating reveals and wainscoting creates a sophisticated and durable amenity for Solano County. To address the Owner’s desire to create a lasting facility, the structural design utilizes seismic design parameters based on 100 year recurrence intervals; twice the timeframe typically considered by code. This approach directly addressed the Owner’s goals without adding unnecessary cost. To further anticipate the changing needs of this health and social services facility, areas of the building are specifically designed for the removal of exterior walls to accommodate future expansion.
