Earthquakes as a Catalyst for Earthquakes as a Catalyst for ChangeChange
• Major advances in the structural engineering art are associated with damaging earthquakes.– 1933 Long Beach– 1964 Alaska– 1971 San Fernando– 1989 Loma Prieta– 1994 Northridge– 1995 Kobe

• The Earthquake demonstrated Deficiencies in:– Building Design Codes– Code enforcement process
• Plan review• Construction inspection

The Foundation Pillars for Achieving the The Foundation Pillars for Achieving the Targeted Seismic Performance LevelTargeted Seismic Performance Level
The 1972 Hospital Seismic The 1972 Hospital Seismic Safety Act (HSSA)Safety Act (HSSA)
The HSSA Establishes Hospitals as essential facilities and defines explicitly their expected performance.
The 1st Ever Definition of The 1st Ever Definition of FunctionalityFunctionality
…. that hospitals, that house patients that hospitals, that house patients who have less than the capacity of who have less than the capacity of normally healthy persons to protect normally healthy persons to protect themselves, and that themselves, and that must be must be reasonably capable of providing reasonably capable of providing services to the public after a disasterservices to the public after a disaster,, shall be designed and constructed to resist, insofar as practical the forces generated by earthquakes, gravity, and winds.
The Need for a Statewide The Need for a Statewide Enforcement AgencyEnforcement Agency
• Laws and regulations w/o rigorous enforcement are ineffective.
• OSHPD/FDD is the enforcement agency of the HSSA.– Primary Responsibilities
• Design Plan Review• Construction Oversight

Why SB 1953?Why SB 1953?
• 1994 Northridge quake critically damaged major hospitals - SB 1953 enacted– Protect life and property– Provide for treatment of injured– Protect investment– Reduce demand on post-earthquake
resources
What is SB 1953?What is SB 1953?
• Evaluation– SB 1953 classifies buildings by risk
(1=worst, 5-best)• Structural (SPC-1 to SPC-5)• Nonstructural (NPC-1 to NPC-5)
• Database of Hospital Building Stock• Retrofit to prevent collapse and loss of life• Retrofit to provide continued operation
after an earthquake

What Should Hospitals Be Doing What Should Hospitals Be Doing Today?Today?
• Mitigation Strategies– Conversion
– Seismic Retrofit
– Replacement
Delays in ComplianceDelays in Compliance
• Diminished Capacity– Request by 01-01-07
• SB 1801 (no longer Available)
• SB 2006 – 2030/NPC 3/Zone 3
• SB 1661– 2015 Compliance/Under Circumstances beyond
hospital’s control
• SB 306– 2020/Fully Compliant Hospital Buildings Sooner
The Next Compliance The Next Compliance Milestone 2013Milestone 2013
• SPC-2– Advanced Analysis/Seismic Retrofit/HAZUS
Reassessment
• NPC-3 – NPC-3 Specific Areas
• Critical Care Areas, • Clinical laboratory service spaces,• Pharmaceutical service spaces,• Radiological service spaces; and• Central and sterile supply areas.
Parting ThoughtsParting Thoughts
• SB 1953 Stimulates realistic long-term planning.
• When in doubt call us
• “Do nothing alternative” is not a solution– Phased but Continuous Mitigation over time
will achieve compliance in the end
