' TAI i@6Associates,inc. On -Call Water Resources Engineering Services As utility records are received, TA|Twill update the project base map to ensure the plans have the most recent alignment, size, type and depth of utilities currently present. TAIT will coordinate with all present and affected utilities during the course of the design. All potential conflicts with the improvements will be identified, and contact will be made with the appropriate utility coordinator. Utility permits are not anticipated as part of this contract. UtilitV Potholing Tait will develop a potholing plan to identify locations in the field where field potholing may be required to finalize the project's vertical alignments. Abased on a review of each project segment Tait has identified potentially a total of 30 potholes that may be required. After the approval of the preliminary water line pipe alignment and connection points, Tait will I identify each pipe crossings using record drawings, field observations and field survey data. Of the total number ofpipe crossings identified, Tait will then identify the most critical crossings that would require further investigation. The critical locations will then be used to develop a Potholing Plan forthe project. This Plan will then be submitted to the City for approval of the Potholing Plan and the contract required number of potholes being proposed. Tait'sFee Proposal provides acost bepothole, the cost for afull day ofpotholing (approximately five tosix potholes based on the pothole locations and traffic conditions encountered) and the total cost to do the 30 potholes initially identified by Tait in the development of our proposal project understanding. Based on the final Number of Potholes the city will identify the proposed approach to address the cost of conducting field services portion of the project's utility potholing. Utility Potholing - Field Services — OPTIONAL TASK TAIThas obtained the services ofBess Tes lab|nc(8TL) inorder toprovide any required potholing nnthis contract. |norder tomaximize the benefit ofthe potholing activities, TAK proposes to conduct all potholing services during the preparation of the 60% plans. Pothole locations will be tied to existing features in the field in order to accurately represent the location ofthe potholes onthe plans.
