State of California Bid 10091115 RFQ No. 10091115 STATE OF CALIFORNIA – CALIFORNIA NATURAL RESOURCES AGENCY EDMUND G. BROWN JR., Governor DEPARTMENT OF WATER RESOURCES Division of Engineering 1416 9th Street, Room 406-10 Sacramento, CA 95814 REQUEST FOR QUALIFICATIONS NO. 10091115 Synthetic Seismic Record Library Development Services TO ALL PROSPECTIVE APPLICANTS October 21, 2013 The Department of Water Resources (DWR), Division of Safety of Dams invites individuals or individuals associated with a firm with extensive background in Engineering Seismology to submit a Statement of Qualifications (SOQ). The Department of Water Resources (DWR) is seeking an individual (who may be associated with a firm) to provide engineering seismology services. In order for DWR to better analyze the effects of high magnitude earthquake events on regulated dam structures, the selected Contractor will help DWR staff to (1) establish a library of synthetic ground motion records, (2) develop procedures and infrastructure to develop additional synthetic time histories, (3) implement the Broadband Platform software developed by the Southern California Earthquake Center (SCEC), and (4) train DWR personnel in SCEC software usage. A copy of the Request for Qualifications (RFQ) No. 10091115 is enclosed. The RFQ contains a description of the qualifications required and directions for preparation and submittal of your response. The SOQ must be received by 2:00 p.m. on Tuesday, November 12, 2013, at the address indicated in Section VI of the enclosed RFQ. The Contractor may be required to work independently or partner with other DWR employees or private professionals but always at the direction of the DWR. The anticipated term of this agreement is January 7, 2014 through December 31, 2015. The Department reserves the right to cancel or modify this RFQ up to the date and time the SOQ is due and to waive non-material defects with any of the SOQs. Additionally, the Department is not responsible for any preparation costs incurred by parties submitting a SOQ. A copy of the State’s General Terms and Conditions is not provided in this RFQ. However, they are available at Internet site http://www.ols.dgs.ca.gov/standard+language and may be downloaded and printed for your files. These terms and conditions will become a part of the contract language and are NON-NEGOTIABLE. Any issues regarding these terms and conditions MUST be addressed during the question and answer period. If you do not have Internet capabilities, you may request a hard copy by contacting the person listed in Section II of the RFQ. The Contractor Certification Clauses (also available at the Internet site referenced above) contain terms and conditions that may apply to person(s) doing business with the State of California, and that may apply to your agreement. If awarded the contract, you must sign and return Page One of the CCC 307. The Certification must be renewed every three (3) years and will be updated when the State makes revisions to the clauses. Please follow instructions in Section II of the enclosed RFQ for questions regarding services to be performed or submission requirements. Sincerely, Douglas Ellis, Contract Manager Division of Safety of Dams Enclosure 10/23/2013 4:10 PM p. 3 Figure 1: Public notice from California Department of Water Resources showing their plans to use the SCEC Broadband Platform. This DWR contract has been awarded to URS Corporation, a documented example of how the NSF SI2 program, through its investment in SCEC’s SEISM software, has produced community software (the SCEC Broadband Platform), and created new non-federal jobs. Figure 2: Two CyberShake hazard models for the Los Angeles Region calculated on Blue Waters in SEISM Project year 2 using a simple 1D earth model (left) and a more realistic 3D earth model (right). Seismic hazard estimates produced using the 3D earth model show (1) lower near-fault intensities due to 3D scattering, (2) much higher intensities in near-fault basins, (3) higher intensities in the Los Angeles basins, and (4) lower intensities in hard-rock areas. Figure 3: Summary results and analysis of simulations for the Mw 5.4 2008 Chino Hills earthquake using different velocity models (CVM-S and CVM-H) and showcasing the connection from geoscience modeling to engineering applications. The top row shows results corresponding to the simulation done using CVM-S, while the bottom row shows those corresponding to CVM-H. Each column from left to right shows: (1) The surface shear wave velocity for each model. 3D meshes built for these simulations consist of up to 15 billion finite elements. (2) The simulation results for the surface horizontal peak ground velocity. The star indicates the epicenter location. (3) Validation results using goodness-of-fit metrics to compare synthetics to data. In this study we used over 300 recording stations. GOF scores closer to 10 (lighter colors) indicate a better fit with the data. (4) Comparison with attenuation relationships used in engineering to estimate peak ground velocity. The red line corresponds to the actual trend from earthquake data, the two black lines indicate an upper and lower bound based on empirical relationships, and the green line shows the trend of the surface results from the simulation, which are shown as a gray cloud of points on the background. Figure 2: Subset of 8 stations comparing the results of simulations using various velocity models against the corresponding time series recorded at selected seismic monitoring and strong ground motion stations during the 2008 Chino Hills earthquake. We did comparisons for over 336 stations.

Figure 4: Results from two 0-10Hz deterministic ground motion simulations using a earthquake source description created by a dynamic rupture simulation along a rough fault. Two different 3D velocity models were used, showing the impact of adding small-scale heterogeneities into velocity models used for high frequency deterministic simulations.

Figure 6: This plot compares decay of ground motion with distance for a M6.6 earthquake as predicted by existing GMPE’s and by Broadband Platform simulations, and it identifies an acceptance criteria new methods must meet before use in building engineering studies. SEISM scientists and civil engineers defined this test to evaluate new ground motion simulation methods. This evaluation method was integrated into the Broadband Platform and used to evaluate 6 alternative ground motion methods.
