Sonoma Valley Hospital Facilities Improvement Project

Sonoma, CA

Sonoma Valley Hospital required seismic upgrades to its aging buildings and infrastructure to be in compliance with Office of Statewide Health Planning and Development (OSHPD) seismic standards.  The Buehler team used the Federal Emergency Management Agency’s (FEMA) HAZUS software to assess the seismic hazards and evaluate strategies to mitigate the potential losses. By utilizing the HAZUS methodology, seismic upgrades were minimized and the central wing of the hospital was saved from demolition.  These savings allowed the construction of a new 30,000 square foot Emergency Department and Surgery Center to be included in the project within the original project budget.
