6 Background 1983 Alquist Act 6 Implemented in 1983 Established a seismic safety building standards program for hospitals built on or after March 7, 1973 Initiated because of the loss of 50 lives incurred during the Sylmar earthquake of 1971 (magnitude 6.6) Emphasized that essential facilities such as hospitals should remain operational after an earthquake. Applied to new facilities only

7 1994 Northridge Earthquake 7 Hospitals built in accordance with the Alquist Act resisted the January 1994 Northridge earthquake (magnitude 6.7) with minimal structural damage, but certain nonstructural components of the hospitals did incur damage Several facilities built prior to the act experienced major structural damage and had to be evacuated

8 Senate Bill 1953-Seismic Retrofit Revisited 8 Senate Bill 1953 (SB1953) Hospital Facilities Seismic Safety Act Introduced February 1994, became law September 1994 Amendment to and furtherance of the Alquist Act. Deemed to be emergency regulations and became effective March Developed to address the issues of survivability of both nonstructural and structural components of hospital buildings after a seismic event.

9 Senate Bill 1953-Seismic Retrofit Revisited 9 Senate Bill 1953 (SB1953) (Hospital Facilities Seismic Safety Act) Applied to all facilities, new and existing Required analysis, upgrades, and reporting criteria No funding provided with the requirement for upgrades self funded by facilities

10 Early Direction 10 All acute care facilities need to withstand earthquake and remain operational Both structural and non-structural components of existing facilities would be upgraded Allowed for phased implementation to occur Most all acute care buildings built prior to 1973 would be required to be replaced by 2030

11 Statewide Analysis 11 Original estimates for compliance were $14B March 2002 California Healthcare Association study estimated the cost of compliance at $23.8B Excluded FF&E, land, professional fees Exceeded the total undepreciated assets of all California hospitals April 2002 RAND Corporation study estimated the cost of compliance at $41.7B Assumes $1M per bed, more than 41,000 beds statewide

13 $M Scripps Project Budgets Over Time 13 $350 $300 $250 $200 $150 $100 $50 $0 FY2006 FY2007 FY2008 FY2009 FY2010 Current Year

14 What Changed? 14 HAZUS Implementation Took into account expected ground motion at site May 2009 Meeting with State Building Official Intent clarification on existing acute care buildings Buildings should be safe to exit No requirement to remain operational

15 Get Engaged in Process 15 Without significant communications, strategy meetings, Owner involvement, outcomes could have been different Identifying the Building Official who could appropriately interpret the code took time Continued meetings with that Building Official was paramount to continuing the process outlined

20 20 OSHPD History & Role

21 It is not about California 21 HAZUS History o HAZUS is a nationally applicable standardized methodology to estimate potential losses from earthquakes, floods, and hurricanes. o HAZUS is developed by FEMA. Development began in the early 1990s. In 1997 FEMA released its first edition named HAZUS97.

22 It is not about California 22 HAZUS developed for a region o HAZUS uses Geographic Information Systems (GIS) technology to estimate physical, economic, and social impacts of disasters on any given region in the whole country. o HAZUS graphically illustrates the risks of different regions due to earthquakes, floods, and hurricanes. o HAZUS software incorporates HAZUS method and state-of-the-art database on local building inventory and hazard characteristics.

23 It is not about California 23 How California uses HAZUS to identify buildings vulnerability for earthquakes o OSHPD has adapted HAZUS to calculate probability of collapse of an individual nonconforming hospital building in an earthquake. o OSHPD-HAZUS method has been added to California Administrative Code o OSHPD-HAZUS has designated selected structural deficiencies as significant and it evaluates their impact on a specific building s vulnerability to earthquake o Total 17 deficiencies are considered

24 It is not about California 24 List of Deficiencies 1. Age: pre-1933 is considered a deficiency 2. Materials Tests: Material tests are required 3. Mass irregularity 4. Vertical discontinuity 5. Short captive column 6. Material deterioration 7. Weak columns 8. Wall anchorage 9. Redundancy 10. Weak story irregularity 11. Soft story irregularity 12. Torsional irregularity 13. Deflection incompatibility 14. Cripple walls 15. Topping slab missing 16. Load path 17. Diaphragm opening adjacent to shear walls

25 It is not about California 25 How we can use HAZUS for other future hazards for the rest of the country o The word HAZUS is an abbreviation of HAZards United States. o HAZUS has been developed to evaluate impact of natural hazards (earthquake, hurricane, and flood) for any region in the U.S.

26 It is not about California 26 Earthquakes occur in other parts of the United States, including the Western coast states, the mid-central region and New York. A 5.0 magnitude-quake was recorded in Indiana a couple years ago and fault zones occur in several Eastern states. California is the only state to establish seismic standards for hospitals

27 Design Team Collaboration 27 Continuous evaluation of upgrade and its effect as design progress Check interference problems-architectural, structural and MEP Arrive to better solutions early in design process Continuous discussion with owner and its construction manager to understand effect of hospital operation Look for alternatives and use latest techniques in design and construction Use of fiber wrap to reduce upgrade Provide test results and technical papers to agency for fiber wrap superb performance

28 Fiber Wrap Composite System 28 Application & Use: o Alternative to conventional shotcrete with advantages of adding capacity while maintaining same rigidirt o Can be used to increase strength and capacity of existing concrete and masonry elements o Can be used for beams, slabs, columns and connections o Unlike shotcrete, does not add to thickness of element, do not require rebar, do not require panel test o Typical use include seismic retrofit, historical preservation, strengthening due to corrosion, strengthening due change of use or added load

29 Fiber Wrap Composite System 29 Material & Technical Data: o Comprised of high tension strength chemical epoxy reinforcing fabrics o Carbon fabrics are oriented in 0, or 45, or 90 degrees depending on application and tension direction o There are both uni-directional carbon fabrics and also multi-directional o Can be applied in one layer or multiple layers based on capacity needed o Can be considered non-porous material and almost any type of finish material can be applied over fiber wraps

30 Design Team Goal 30 Utilize latest analysis & design techniques 1. Utilize out of the box thinking 2. Utilize state of the art materials for retrofit/upgrade Have design shreds to identify effects on upgrade areas 3. Explore various options to accomplish desired objectives (i.e., scenario studies) 4. Design upgrades that are quick to construct & less interruptive/noisy Minimize upgrade effect on operation Open communication with design & construction team Minimize overall cost

31 31 Design Team Goal

32 Team Integration 32 Engage owner early in design and discussions with building officials Communicate with agency for design assumptions Continuously discuss with design team for upgrade effect on operation Engage facility staff in upgrade options Involve contractor in upgrade scheme studies

33 Team Strategy 33 Achieve excellence in design through collaboration and using latest techniques Achieve excellence in construction utilizing latest construction materials Communicating with agency to understand their specific requirements Put the project on high priority due to mandated deadlines Agency Construction Manager Contractor Owner Design Team

34 Owner & Agency Participation 34 Communicate with agency continuously Present agency with plans of upgrade as it develops Validate owner goals and requirements Validate code intent and making sure we are providing what is needed per code

35 Building Upgrade in Operational Hospital 35 Identify areas of upgrade early in design Meet with A&E team to understand upgrade options and their affect Verify existing conditions in the field Discuss with facility for upgrade effect on their operations Adjust/modify the upgrade elements to reduce effect on operations

36 Comparison of Different Upgrades 36 Effect of full upgrade on building systems and operation Effect of voluntary seismic improvement on building systems and operation Compare the results Identify time/ cost savings

37 Comparison of Different Upgrades 37 SPC-2

38 Comparison of Different Upgrades 38 Incidental

39 Utilizing Latest Innovations 39 Model with ETABS or SAP analysis Typical analysis method commonly used Analysis is linear & provided approximate representation of building behavior Model the building utilizing non-linear analysis Technically challenging and computationally intense Provides more accurate and realistic presentation of building response and help understand behavior better Help reduce seismic retrofit significantly including foundation and walls Takes more time for analysis, design & also OSHPD review TTG has superior knowledge & skills for nonlinear analysis

40 Utilizing Latest Innovations 40 Utilize HAZUS building model to identify probability of collapse Developed by FEMA in early 1990 s HAZUS=Hazard US A method that estimates the probability of damage, collapse and loss in an event OSHPD has adopted HAZUS by some modifications TTG has acquired substantial skills and knowledge to run HAZUS before OSHPD and help owner make decision Help to further reduce seismic upgrade of buildings through incidental upgrade Due to further reduced seismic retrofit, facility stays fully open and interruptions are minimal

41 Project Savings 41 Project construction cost reduced from $180M to $30M Tremendous cost savings to operation due to minimum upgrade elements Time savings for early completion

42 Lessons Learned 42 Use latest design tools available Collaborate with design team, owner and state agency It pays to think outside the box Identify issues early and collaborate with the team Find solutions together after all, this is a team effort
