• Detailed discussion of any applicable safety, security or other site issues <br />• Feasible alternatives for repairs, retrofit or replacement to address any deficiencies identified provide <br />for each structure. The alternatives will consider geotechnical conditions, visual impacts, construction <br />feasibility, impacts to current facility operations, and an estimate of the remaining useful service life with <br />each alternative implemented. Each alternative will include an opinion of probable cost accounting for <br />all planning, permitting, design and construction activities. <br />• Prioritization of the repair/retrofit/replacement alternatives, highlighting formal recommendations of <br />which alternative should be implemented for each reservoir; the report will contain a matrix that <br />graphically enumerates and prioritizes the alternatives. <br />A draft report will be submitted to the City for review and comment. After meeting with City staff to review and <br />receive comments on the draft report, Tetra Tech will finalize the report, including in the final report a <br />conceptual plan for the recommended alternative for each reservoir. <br />The final report will be sealed and signed by Mr. Yuen, a California -licensed Structural Engineer. Tetra Tech <br />will provide three hard copy color reports and one PDF digital copy of the final report to the City. <br />Task 5: Value Added Services <br />As an optional scope item, Tetra Tech will provide a formal PowerPoint presentation of the final findings <br />and recommendations to City staff. This will help City staff to have a better understanding of the final <br />comprehensive engineering report, which will allow the City to make future reservoir retrofit and <br />replacement decisions more effortlessly. <br />Future Task: Final Engineering Design, Bid and Construction Support Services <br />Final Plans. Specifications & Estimates <br />Upon final review and acceptance of the comprehensive engineering report by the City, we will proceed <br />to begin the preparation of final design construction documents —the plans, specifications & estimates — <br />to be submitted at 60%, 90% and 100% stages of development. The preparation of the construction <br />documents will be based on the selections made by the City from the comprehensive engineering report <br />recommendations. Since the effort required to develop the final design construction documents heavily <br />depends on the actual condition of the existing reservoirs, which is not known at this moment, a separated <br />fee proposal will be provided when requested by the City after the retrofit option is selected. <br />Bid Support Services <br />Tetra Tech will assist City staff as required in the bid process, including attending the pre -bid meeting, <br />answering bidders' questions, and preparing addenda and conformed documents. <br />Construction Phase Support Services <br />Tetra Tech will assist the City in reviewing shop drawings, responding to contractor requests for <br />information, and preforming observations during construction. <br />e. RELEVANT PROJECT EXPERIENCE <br />Tetra Tech conducted condition assessments, <br />inspections, and investigations, performed <br />testing and provided structural and seismic iWAI <br />evaluations of nine water storage reservoirs, <br />eight of which were concrete reservoirs. <br />Deficiencies were identified and presented <br />with prioritized alternatives for repair, retrofit or replacement to <br />ensure these facilities continue to operate and provide water <br />following a seismic event. The District's nine water storage reservoirs <br />have a combined volume of 11.5 million gallons at full capacity. Tetra <br />Tech provided design phase services of the retrofit for two of the <br />concrete reservoirs. <br />CITY OF SANTA ANA <br />TETRA TECH <br />
