Well #32 Rehabilitation Engineering Services useful in determining thin (weak) areas of the The Basis of Design will include, but not be limited casing where corrosion may have removed a to, such issues as: significant amount of metal, which could result in the eventual formation of holes in the casing. T An overall evaluation of the existing Well station based on current design standards. We would be glad to meet with the City to discuss 2 the advantages of removing the pump and the additional data that can be obtained from these tests. Task Operational Project Design Standard t. Criteria Tetra Tech will work with City staff to determine the applicable design standards and criteria in addition to those defined by the Study. We will consider other possible agency design criteria and/ or standards as necessary. A maximum of three 3-hour workshop sessions shall be conducted with the Project Manager, City Operations staff and the Tetra Tech design team. We will organize the meeting including obtaining background information for discussion, preparing the agenda, compiling meeting minutes and action items, as well as distributing the minutes as required. Elements to be discussed shall include, but not be limited to, operational parameters, ideal control conditions, and operator experience. Upon completion of Tasks 2 through 5 above, Tetra Tech will prepare a Basis of Design Report including elements and findings from all of the Tasks. The Basis of Design Report shall summarize all of the alternatives and outline the agreed upon alternative including reasons why the alternative was chosen. The Basis of Design Includes 30% drawings of the chosen alternative including all proposed improvements. The Basis of Design Report shall be stamped and signed by a California Registered Civil Engineer. Prior to completion of the final Basis of Design Report, Tetra Tech will prepare and submit for review a draft Basis of Design Report to City staff. Make recommendations for Well #32 improvements including site alternatives (two minimum) for the building as well as related discharge piping. Propose possible building architectural features that can be incorporated into the local neighborhood surroundings and provide concept drawings of the new building. We have assumed we will consider two roof type options — a gabled roof and a fiat -top roof with a parapet. We have also assumed that the building will be a CMU building, similar to other City facilities. We will work with the City and discuss building aesthetics and what can be cost-effectively accomplished to better assimilate the building into the park and the surrounding residential area. We have assume the preparation of two renderings, one for each building type. 3. Identify new Well #32 station improvements needed to improve operations, reliability, and safety. The City would like to re -develop this Well. Inform the City of the ideal method for rehabilitation upon review of as-builts and well survey video. In addition, the criteria as defined in the Study shall be met, although additional improvements related to the selected design criteria may exist. Note: this well site is not expected to have a permanent back-up power system on -site. 4. Prepare preliminary electrical design plans for the motor control center, Well #32 RTU control panel, Garthe Pump Station RTU control panel and related appurtenances. The City desires that the existing motor control center (MCC) at Garthe Pump Station remain in place and be tied into the new RTU panel. 5. Make recommendations for communications between Well #32 and Garthe Pump Station. We will look at two alternatives for stable communications between both sites: radio
