FOR PROFESSIONAL ENGINEERING SERVICES FOR PRELIMINARY DESIGN FOR THE SEISMIC UPGRADES FOR THE PUMP AND BLOWER BUILDING, DISTRICT PROJECT 7291 Submitted By: Initiating Dept /Div.: Nathan Hodges, Assistant Engineer Engineering / Capital Projects REVIEWED AND RECOMMENDED FOR BOARD ACTION: /t!' _ T Is T - T�, N. Hodges B. Than�T. Pilecki A. Farrell Ja .Kelly, General Manager ISSUE: Board of Directors' authorization is required for the General Manager to execute a professional services agreement in an amount greater than $50,000. RECOMMENDATION: Authorize the General Manager to execute a professional services agreement with Complete Project Solutions, Inc. with a cost ceiling of $60,000 for preliminary design work. FINANCIAL IMPACTS: This preliminary design work is intended to more accurately define potential costs for the design and construction of retrofits to the Pump and Blower Building (PBB) to meet current seismic codes. Preliminary estimates are that the construction of needed retrofits would cost in the $2 million range for the PBB. The final design costs will depend on the type of retrofit design selected. ALTERNATIVES /CONSIDERATIONS: The District could elect not to pursue this preliminary design work. This is not recommended, because our preliminary analysis indicates that significant damage could occur to the PBB in the event of a large earthquake (magnitude of 6.7) on the Concord fault. If the project is to move forward, outside consultants must be used because District staff does not have this specialized expertise. BACKGROUND: Design of structures to withstand forces generated by earthquakes is a field which continues to evolve each time there is a significant seismic event. After each such event, structural engineers review the forces and resultant damages and reanalyze current codes. As a result of the Northridge Earthquake in 1994, significant changes were recommended for the then current building codes. In January 2008, California adopted updated building codes. Based on the knowledge that significant changes in seismic codes had occurred, District staff determined that it would be prudent to conduct a seismic analysis of District facilities.

FOR PROFESSIONAL ENGINEERING SERVICES FOR PRELIMINARY DESIGN FOR THE SEISMIC UPGRADES FOR THE PUMP AND BLOWER BUILDING, DISTRICT PROJECT 7291 This seismic analysis has been completed. The analysis identified significant deficiencies in many District facilities. Some improvements have been incorporated into current capital projects such as Standby Power Facility Improvements and HHWCF. Other facilities with deficiencies that should be addressed are the Headquarters Office Building, Pump and Blower Building, Solids Conditioning Building and Plant Operations Building. Staff recommends proceeding with the preliminary design of the PBB due to the deficiencies found when compared to current seismic design standards and the potential for significant damage to critical equipment housed in the PBB in the event of a major quake on the Concord fault. The chance of such an earthquake occurring is estimated to be 10 percent in the next 50 years. The PBB has deficiencies when analyzed with the current code. The building consists of two halves separated by a 1 -inch expansion joint. When displacements from a design earthquake are calculated, the expected movement exceeds the 1 -inch expansion joint. Earthquake loads are transferred from the roof diaphragm through the steel moment frames. The frames deliver loads to the first floor diaphragm, to the basement shear walls, and into the soil. The calculated stresses in the moment frames exceed their design capacities. The worst case implication of this overstress would be collapse of the PBB. A more likely scenario is that the building remains standing, although severely damaged, after the initial earthquake. Subsequent aftershocks could collapse the building or further damage the building. This building houses critical treatment equipment such as primary and final effluent pumps, aeration air blowers, and service air compressors. Treatment plant operations would cease with the loss of any of this equipment. For this reason, additional engineering analysis of this structure has been given high priority. Complete Project Solutions, Inc. (CPS) has extensive experience in seismic analysis and design and were selected to do the initial seismic analysis of all District structures. Because of their expertise, their familiarity with District facilities and their preliminary work on the PBB, staff recommends CPS performs the seismic preliminary design for the PBB. A professional engineering services agreement with a cost ceiling of $60,000 has been negotiated with CPS. The scope of work also includes peer review of the HOB Seismic Improvements preliminary design to be performed by KPFF Consulting Engineers because CPS did the original seismic analysis of the HOB structure. This preliminary design is the first step in the design process. The Board's Capital Projects Committee has reviewed the proposed pre- design and recommends approval. Staff will come back to the Board of Directors for approval of further design work when a retrofit concept and a detailed design scope have been developed.

FOR PROFESSIONAL ENGINEERING SERVICES FOR PRELIMINARY DESIGN FOR THE SEISMIC UPGRADES FOR THE PUMP AND BLOWER BUILDING, DISTRICT PROJECT 7291 The Seismic Upgrades for the Pump and Blower Building is included in the 2010 -2011 Capital Improvement Budget on pages TP -49 and TP -50. Staff has determined that there are adequate funds available and that the expenditure requirements are consistent with the Treatment Plant Program. Staff has evaluated this action and concluded it is exempt from the California Environmental Quality Act (CEQA) under CCCSD CEQA Guidelines Section 15262, since the agreement would be used for design studies for possible future actions which CCCSD has not approved, adopted, or funded, and the outcome of these tasks will not have a legally binding effect on later activities. Approval of this action will establish the Board of Directors' independent finding that the action is exempt from CEQA. The Board of Directors further finds that CCCSD will produce appropriate CEQA compliance documentation prior to undertaking any "project" arising from these design studies. RECOMMENDED BOARD ACTION: Authorize the General Manager to execute a professional services agreement with Complete Project Solutions, Inc. with a cost ceiling of $60,000 for preliminary design of the Seismic Upgrades for the Pump and Blower Building, District Project 7291.
