OSHPD Proposes a New Seismic Design Category: SPC-4D
Details of the proposed SPC-4D building design category and how to determine eligibility

Webinar Recorded Live on May 12, 2015


The Office of Statewide Health Planning and Development (OSHPD) has developed proposed building standards for a new seismic design category — Structural Performance Category 4D (SPC-4D), which meets the requirements of the Hospital Facilities Seismic Safety Act and acceptable structural engineering practices. The proposed standards are under review by the California Building Standards Commission.

If adopted, SPC-4D will provide an alternative seismic category for hospitals to consider in meeting their 2020 and/or 2030 deadlines.

Learn about the proposed SPC-4D building design category and find out if SPC-4D may be an alternative to consider.

Recommended For: Chief operating officers, compliance officers, plant managers, facilities construction directors, construction managers and environmental services directors.


  • How we got here — Hospital Facilities Seismic Safety Act (HFSSA), SB 1953
  • Current seismic categories, reasons for introducing SPC-4D
  • Regulatory process – where it now stands
           – Establishing SPC-4D timeline, future extensions
  • Why consider —  benefits of the SPC-4D category
           – Extended compliance lead time, budget planning, finance opportunities
              and more
  • Which hospital buildings may be eligible — building type, geotechnical prerequisites
  • Process to determine eligibility
           - Role of structural engineers and other professional designers
  • Looking forward — if  SPC-4D category is adopted by California Building Standards Commission
           - Why hospitals must start planning now
           - Potential effective date, how soon the category can be used
