Presentation Outline Introduction Current Conditions Background / History Standards Enforcement Best Practice Certification Q&A Discussion
Current Conditions In a Round Table Discussion with OSHPD Director on April 22, 2014 we learned: The Majority of Work in Progress at OSHPD are Projects with Construction Value < $ 200,000 Only a Couple of Large Projects under Construction Sutter: CPMC San Francisco Kaiser: San Diego Stanford: Palo Alto Marked Decline in Work Volumes Attributed to: General Economic Conditions Healthcare Reform Seismic Compliance Delays

Background / History What about the Black Box?
Background / History 1976 UBC Good idea but does anyone really care? (k) Essential Facilities. Essential facilities are those structures or buildings which must be safe and usable for emergency purposes after an earthquake in order to preserve the health and safety of the general public. Such facilities shall include The design and detailing of equipment which must remain in place and be functional following a major earthquake shall be based upon the requirements of Section 2312 (g) [Lateral Force on Elements of Structures] and Table No. 23-J.
Background / History 2000 IBC 1708.5 Mechanical and electrical equipment. Each Maybe we do care? manufacturer of designated seismic system components shall test or analyze the component and its mounting system or anchorage and shall submit a certificate of compliance The evidence of compliance shall be by actual test on a shake table, by three-dimensional shock tests, by an analytical method using dynamic characteristics and forces, by the use of experience data (i.e., historical data demonstrating acceptable seismic performance), or by a more rigorous analysis providing for equivalent safety.
Background / History Drivers of Change - Earthquake Lessons Learned
Background / History 2006 IBC / 2007 CBC Yes, we care. So now 1708.5 Seismic qualification of mechanical and electrical what? equipment. The registered design professional in responsible charge shall state the applicable seismic qualification requirements for designated seismic systems on the construction documents Qualification shall be by an actual test on a shake table, by threedimensional shock tests, by an analytical method using dynamic characteristics and forces, by the use of experience data (i.e., historical data demonstrating acceptable seismic performance) or by a more rigorous analysis providing for equivalent safety.
Codes and Standards
Enforcement What Changed? IBC vs CBC: Some Noteworthy Difference in Requirements for SSC. Enforcement has been the Source of PERCEIVED CHANGE. On January 1, 2008 OSHPD began to enforce the requirement for SSC as prescribed in the 2007 CBC. Even today, many jurisdictions still do not enforce this part of the building code.
Best Practice Validate the Structural Integrity and Functionality of the Equipment. Validate the Seismic Anchorage and Restraint of the Equipment

Best Practice Gather the Critical Information Essential Site / Building Information Essential Building Systems / Equipment Components Information
Best Practice Essential Site / Building Information Site Class Spectral Accelerations Risk (Occupancy) Category Seismic Design Category Permanent or Temporary Installation General Structural System Support Compatibility Installation Location in the Building
Best Practice Risk (Occupancy) Category Essential Buildings: IV I-2 Occupancies (Hospitals) Fire, Rescue ambulance, Police Stations Designated Earthquake Shelters, Emergency Preparedness, communications and operations centers. Structures Containing Toxic Materials Aviation Control Towers, Buildings having National Defense Functions Water Storage and Pump Structures for Fire Suppression
Best Practice Essential Building Systems / Equipment Components Component Importance Factor Designated Seismic Systems Amplification Factor ap Response Modification Factor Rp Exemptions to design requirements of ASCE 7-10, Chapter 13 Manufacturer Special Seismic Certification Manufacturer OSHPD Pre-Approvals (Voluntary Programs) Manufacturer Product Data Information (Cut Sheets)
Best Practice Essential Building Systems / Equipment Components Manufacturer s Certification by Analysis, Shake Table Testing or Experience Data. (NOT Special Seismic Certification) Manufacturer Installation Drawings Support Conditions (Flexible / Rigid, Floor, Overhead, Wall Mounted) Specialty Support Documentation (Vibration Isolation)
Best Practice Designated Seismic Systems The seismic force-resisting system and those architectural, electrical, and mechanical systems or their components that require design in accordance with ASCE 7-10, Chapter 13 and for which the component Importance Factor is greater than 1.0. Equipment that is part of the Designated Seismic System must remain Operable following an Earthquake
Best Practice Component Importance Factor (Ip) All components shall be assigned an Ip value. Ip = 1.0 except where The component is required to function for life-safety purposes. (Fire Alarm and Fire Sprinkler Systems). Ip=1.5 The component contains hazardous materials. (Fuel Tanks etc). Ip=1.5 The component is in or attached to an Risk Category IV Structure. Ip=1.5
Certification Methods Project Specific Special Seismic Certification and Seismic Restraint Calculations. Applicable to the Site and Project Conditions Only. Pre-Approved Special Seismic Certification (OSHPD OSP Program) and Anchorage (OPM Program Applicable to Multiple Sites where Site Conditions and Product Construction are Acceptable
Certification Methods Site / Project Specific Certification The Design Professionals of Record for the project are responsible to VALIDATE the application of a Special Seismic Certification for their specific project. Must include specific information from shake table testing. The Design Professionals of Record are responsible to VALIDATE Equipment Anchorage
