USGS website. The obtained PGA's will be used for the reservoir <br />seismic analysis to determine: <br />a. Concrete wall horizontal/circumferential stresses <br />and reinforcement <br />b. Concrete wall vertical <br />reinforcement/prestressing <br />C. Seismic cable stress for circular reservoir <br />d. Sloshing and freeboard <br />e. Roof slab, floor slab and foundation <br />Following the reservoir structural and seismic analysis, repair <br />approaches for concrete roofs, exterior wall surfaces, interior wall <br />and roof surfaces, interior columns and observed leakage will be <br />developed. <br />Corrosion Assessment <br />After the initial corrosion assessment is complete and additional <br />testing, if required, performed, prepare a Repair Strategy, including <br />the budget level construction costs to mitigate existing and <br />anticipated corrosion problems in the reservoir. The report will <br />include a report on the conditions of the: <br />• Coating protecting; <br />• All steel appurtenances; <br />• Inlet/outlet; <br />• Overflow and drain piping; <br />• Replacing coatings including corroded metal appurtenances <br />with fiberglass; Polyethylene; PVC; Polypropylene or FRP <br />appurtenances; and/or adding cathodic protection as <br />needed. <br />Security Assessment <br />Our subconsultant Triad Consulting, will conduct a security <br />assessment of City of Santa Ana concrete potable water reservoirs <br />listed in the RFP document. The assessment will follow guidance <br />provided by ASCE/AWWA Guidelines for the Physical Security of <br />Water Utilities and ANSI/AW WA G430: Security Practices for <br />Operations and Management Specific tasks include: Meet with City <br />of Santa Ana Water security stakeholders to discuss the security <br />program in place, standards, identified issues, etc.; Site survey the <br />potable water reservoirs listed in the RFP document for adequacy of <br />existing physical and electronic security; Upon delivery of security <br />assessment recommendations report, Triad Consulting will discuss <br />findings and recommendations in a debrief meeting with Santa Ana <br />Water security stakeholders. <br />SUMMARY REPORT <br />Provide a summary report, presenting results of the technical <br />analysis and preliminary studies including the following. <br />a. Field investigation notes <br />b. Results of diver inspections <br />C. Preliminary plans showing. <br />I. Record drawings annotated with locations in <br />extents of cracks and other structural repairs <br />2. Site plans defining various implements envisioned <br />for each location <br />3. Preliminary details of new piping, repairs m <br />appurtenances and replacement of same where <br />needed. <br />d. Structural analyses and alternatives for seismic and <br />structural retrofit requirements <br />• <br />e. Recommendation of any reduction of water levels and <br />roof loads prior to repairs are accomplished <br />f Proposed requirements for coatings and cathodic <br />protection systems <br />g. Recommendations for building structure and other <br />strategies from constructability review input <br />h. Updated project schedule, including construction phasing <br />and durations <br />i. Engineers Opinion of Probable Construction Costs <br />j. If upgrade to reservoir is not economically practical, <br />provide constructability of newly proposed storage facility <br />and preliminary cost associated with any newly proposed <br />facility. <br />Provide hard copies of draft report for City review. It is assumed <br />that City will compile its comments into a single set with any <br />conflicting comments resolved. Beyaz & Patel will compile its <br />comments into a tabular form and provide written responses to <br />comments. Provide hard copies and PDF digital copy for the final <br />report. <br />FINAL DESIGN <br />Geotechnical Report. Beyaz & Patel's licensed geotechnical <br />subconsultant will conduct geotechnical reconnaissance and prepare <br />geotechnical report where required. <br />Plans. Prepare construction drawings for the proposed <br />reservoir repairs. The design will include civil, mechanical and <br />structural drawings. Annotated record drawings from the site <br />assessments will be formulized to provide definition of types <br />and extents of structural and crack repairs and other repair or <br />installation work. Separate plan sets will be developed for each <br />site/reservoir, but will be developed to facilitate combining <br />reservoirs with like features into packages. Plans will be <br />prepared using AutoCAD and conformed to Cit f s drafting <br />standards. <br />2. Technical Specifications. Prepare technical specifications <br />for the construction of the proposed reservoir improvements. <br />Specifications will be prepared in CSI format. Incorporate <br />Cit f s standards as applicable. <br />3. Final Cost Opinion. Prepare final detail opinion of probable <br />construction cost for the project. Any opinion of the <br />construction cost prepared by Beyaz & Patel represents its <br />judgment as design professional and is supplied for the general <br />guidance of City. <br />4. Design Review Submittals. Provide submittals to the City <br />for review and comments at the 90% level of completion. <br />Information developed during assessments and technical studies <br />will constitute between a 30% and 50% submittal. <br />5. Final Submittal. After incorporation of the City review <br />comments, prepare one (1) set of final stamped and signed <br />originals of the construction documents. <br />6. Bid Phase Services. <br />• Attend prebid conference for each phase <br />• Respond to contractor's questions <br />• Prepare one (1) technical addendum per phase <br />• Assist City on the award of the contract <br />Beyaz &Patel 25B-27 Statement of Qualifications I Page 7 <br />
