r Our basic approach to the design services will be to provide the City with an experienced, knowledgeable and enthusiastic staff dedicated to providing the level of service the City desires. Tetra Tech is committing our top senior manager and staff to this assignment in order to ensure that this is accomplished. Our Project Management Team will be able to recognize and anticipate' problems and be able to come to the City with options and solutions in a timely manner. Tetra Tech's experience in design and engineering services covers all facilities in the water, recycled water, and sewer systems including: • PipeIines and force maims • Sewer Relining or Rehabilitation • Reservoirs • Pump, Lift and Flow Control Stations • Water Quality and Disinfection Facilities • Recycled Water Retrofits • Building Renovations • Structural Seismic Retrofits • Planning /Engineering Studies Our recent project experience in these areas is described in a previous section. To keep the City aware of the status of the project, we will schedule and administrate design meetings and prepare monthly progress reports as appropriate for the assignment. The following are typical key issues which we believe must be addressed to successfully complete design services: • Meetingschedule • Coordination with the City and reviewing and permitting agencies • Utility coordination and con /list resolution • Potholing of conflicting utilities • Accouniingfor traffic control during alignment selection • Analyzing alignment alternatives • Providing construction phasing if necessary • Identifying options for pipeline rehabilitation • Hydraulic calculations • Temporary bypass piping /facilities • Facility layout • Operator safety and maintenance friendly • Structure aesthetics match surrounding neighborhood The following summarizes the services we envision that will be required to be performed during the execution of the sample project. In preparation for this project, we have reviewed the "Typical Scope of Work" (Exhibit A) contained in your Request for Proposal. We have found the scope of work presented in the RFP to be comprehensive and due to the proposal space limitations, we have included herein only items of the scope with which we have comments on, additions to and /or want to expand. The project consists of designing approximately 3,200 linear feet of 8 -inch diameter PVC (C -900) water main and 4,100 linear feet of 8 -inch diameter PVC (SDR -26) sewer main improvements. SCOPE OF WORK Task No. 1 PreldnednaryDesign 1. General Administration and Meetings Tet'ra'l'ech and the City of Santa Ana will meet four (4) times after the kickoff meeting (Basis of Design Memo, 50%,90% and 100 %) during the design phase of the project. 4. Potholing A. Verify location of utilities based on USA information obtained and job walk. B. Review USA markings completed by geotoclmical investigation and potholing. C. Identify critical utilities which are recommended to be potholed. D. 'Tet'ra Tech will prepare a memorandum summarizing the pothole recommendations for the City review and approval. E. Provide potholing in the field of up to five (5) utilities for the sewer main, similar to what was done for the Westminster Avenue Sewer Improvements. Please note that during the Westminster Avenue project, the potholes were ultimately performed by City forces. We do not recommend potholing for this size water main and typically recommend potholing when constructing large pre- fabricated M -13- TETRA TECH
