COUNCIL COMMUNICATION FORM Engineering & Infrastructure Memorandum NO. 2004-77 October 8, 2004 TO: Honorable Mayor Osborne and City Council I FROM: Steve Garman, City Manager ' Stephen Swanson, P.E.,Director of Engineering & Infrastructure �>v " II Mathew C. Newell, P.E., City Engineer� Richard N. Berard, Civil Engineer II � SUBJECT: Water Distribution Main from the South Water Treatment Plant to Elevated Tanks, City Project 2003-23—Detailed Design Phase SUMMARY RECOMMENDATION: It is recommended by staff that the City Council approve the attached resolution authorizing an agreement with Bainbridge, Gee, Milanski & Associates, Inc., (BGM) to provide engineering services for the preparation of construction plans and specifications to extend a ' Water Distribution Main from the South Water Treatment Plant (SWTP) to Elevated Tanks for a fee not to exceed $285,000. BACKGROUND: In December 2003, Council authorized a $30,000 agreement with Bainbridge, Gee, Milanski & Associates (BGM) to provide engineering services for a route study and Project Plan to extend water distribution mains from the SWTP to the elevated Tanks. This work is needed to increase the pumping capacity of the high service pumps at the SWTP by reducing the significant pressure losses that currently occur between the SWTP and the City's elevated water tanks. The project essentially links the water tanks and the SWTP together to equalize water pressure in the City's distribution system. The preliminary construction budget is estimated at $4,580,000. City staff recommends proceeding with the next phase of the project,namely the detailed design phase. Engineering costs for projects of this magnitude and complexity are generally expected to be between 6— 10%. The requested fee of$285,000 falls within this range and is reasonable for the work product expected.
