REPORT 6.10 age 1 November 23,2009 SUBJECT . Amendment No.1 to professional services agreement with RMC.Water and Environment for engineering design services for the Glenwood Pump Station Improvements Project RECONlMENDATlON Approve, by motion, Amend"1ent No. 1 to the agreement with RMC Water and Environment to provide engineering design services for the Glenwood Pump Station Improvements Project in the amount of $26,100.00 for a total amended contract value of $132,182.75. BACKGROUND In May 2008, the City Council approved and authorized the execution of an agreement with RMC Water and Environment to provide professional engineering design services for the Glenwood Pump Station Improvements Project for a total amount of $106,082.75. The Glenwood Pump Station Project is necessary to ensure the continued reliability of potable water service to customers in the unincorporated Emerald Hills area. The current pump station is in an open area, exposed to inclement weather and enclosed by a chain link fence, which provides minimal security. The proposed project will provide a small, secure structure to house the pumps, the electrical and telemetry control equipment, and the new emergency stand-by generator. Housing the equipment increases both the security and reliability of the pump station operations and reduces the need for maintenance. It was determined by staff after completion of the preliminary design report that additional evaluation, hydraulic analysis, and revisions to the design to include variable frequency drives for the pumps are necessary. Hydraulic analysis was included in the original scope of work. However, after the preliminary design report, staff realized that additional analyses were necessary to ensure the pump station is capable of providing the flexibility for the future. The additional analyses and design revision will provide insight into how the water system could be operated under emergency conditions and potential effects on the pump station; and improve the efficiency of the pumps. The additional proposed fee for this hydraulic modeling work and revised design is $26,100.00. A categorical exemption will be filed for CEQA process to facilitate construction of the building enclosure. We will also be working closely with the planning department to ensure that the enclosure selected will blend with the neighborhood. AL TERNA TIVES Council may choose not to approve Amendment No. 1 in the amount of $26,100.00 and direct staff to find alternate means of completing the work and/or select another consultant. FISCAL IMPACT Funds for the design of the improvements have been appropriated in Water Fund Capital Projects, G/enwood Pump House & Generator which has an available balance of $386,208.60 as of September 30, 2009.
