Webinar (Will be done online)
Links will be sent soon to registered attendees only



This presentation will provide background on regulations and requirements, current policies of interpretation and enforcement, and recommendations for the practicing Engineer regarding seismic instrumentation of buildings. The presentation will consist of two parts:

Part 1: City of San Diego Development Services

The City of San Diego adopts Appendix L of the California Building Code and has done so since the adoption of the 2016 CBC. Additionally, and as a part of the review of tall buildings requesting code deviations to permit structural systems that exceed the structural heights in ASCE 7, the City requires installation of seismic instrumentation in accordance with the guidelines developed by the Los Angeles Tall Buildings Structural Design Council or equivalent.

The presentation will identify the source for the regulations, applicability, installation inspection/commissioning requirements and will address policies adopted to ensure that the necessary systems are maintained to remain functional for the life of the building.

Part 2: OSHPD

The Health and Safety code requires, insofar as practicable, California hospital buildings to continue to provide services after a disaster and designed and constructed for forces generated by earthquake, gravity, and wind. With practical and monetary limits to laboratory testing, it makes sense to instrument hospital buildings to determine actual performance in an earthquake. There is also a need for use of the instrument recordings to provide automated damage indicators in these instrumented hospital buildings. Such instrumented damage indicators are required to supplement the traditional visual inspections immediately after a seismic event to make quick and reliable decision on whether to evacuate damaged buildings.

Dr. Lobo will highlight the main aspects of the OSHPD seismic instrumentation program, the code requirements that dictate which hospital buildings are required to be instrumented by the owner and the role of the Hospital Buildings Safety Board in designating which existing hospital buildings get slated for OSHPD paid instrumentation. Case studies showing the application and benefits of seismic instrumentation will also be presented.


Dr. Roy Lobo is the Principal Structural Engineer with the Office of Statewide Health Planning and Development and has been with the OSHPD for over Seventeen years.       Dr. Lobo received his doctorate degree in Structural Engineering from the University at Buffalo New York in 1994. He has since worked for several reputed firms in the Los Angeles area before joining the OSHPD and moved to Sacramento in 2003. He is an active member of the structural engineering community with memberships in professional organizations such as the Structural Engineers Association of Central California (SEAOCC) and the American Society of Civil Engineers (ASCE). He was chair of the SEAOC Seismology and Existing Buildings Committees and chair of the same committees for SEAOCC. Roy is a voting member of the ASCE 7-22 and ASCE 41-23 committees and the chair of the ASCE 41-23 foundations subcommittee.

His expertise is in the field on non-linear analysis and is the prime author of the computer program IDARC-3D. In addition to his analytical background in computer modeling and software development, he also has vast design experience in the evaluation and retrofitting of existing buildings. He is currently in charge of the OSHPD Structural Services Unit and he is responsible for promulgating all necessary structural amendments to the California Building Standards Code to align it with the mandates of the California Seismic Safety Act for Hospital Facilities.

Michael Hill, S.E. is a Senior Structural Engineer with the City of San Diego Development Services Department and has been with the City for seven years. Michael earned a BS from Cal Poly San Luis Obispo and a MS from Cal Poly Pomona. He has since worked for several firms in the Los Angeles and San Diego areas before joining the City of San Diego. He is an active member of the structural engineering community with memberships in the American Society of Civil Engineers (ASCE). Michael is a voting member of the ASCE 7-22 wind and main committees and has served on the California Code Advisory Committee.
