Item #29 CITY OF COLTON AGENDA REPORT FOR THE COLTON UTILITY AUTHORITY MEETING OF SEPTEMBER 6, 2005 TO: HONORABLE CHAIRPERSON AND UTILITY AUTHORITY MEMBERS FROM: ERIC R. FRASER, DIRECTOR OF WATER & WASTEWATER OPERATIONS SUBJECT: AWARD OF CONTRACT FOR THE DESIGN, PROJECT INSPECTION AND CONTRACT MANAGEMENT OF WELL 30 AND WELL 31. DATE: August 23, 2005 BACKGROUND: Krieger & Stewart, consultant for the City's 1998 Water Master Plan recommended improvements which are intended to enable Colton to meet anticipated water requirements over the next 10 to 20 years. These improvements call for the construction of eight new wells by the year 2010 in order to effectively meet the recommended water production capacity. Since 1998, four wells have been constructed. Construction of the new proposed wells on City of Colton property will allow for existing demands and water production requirements to be met, out of date well pumping plants to be removed from service, and provide reserve capacity for when wells are removed from service for scheduled and unscheduled maintenance. DISCUSSION/ANALYSIS: The professional engineering firm awarded the contract will design Well Nos. 30 & 31 and will also provide contract management and construction inspection services during the drilling of the wells and installation of the pumping equipment. The project consists of installing two new wells on city of Colton property along Congress and Fogg Street with the discharge pipes running from the new wells out to Fogg Street and northbound to M street. Fencing of the well sites will also be included. A diligent effort was made to solicit proposals for the project from four professional engineering firms. A total of three engineering firms submitted proposals. The formal sealed proposal opening took place on Monday, May 9, 2005 at 4:00 p.m. in the Corporate Yard conference room. Interviews of the three Engineering firms were also conducted on the 9th of May, 2005 in the Corporate Yard conference room. Fee proposals were provided under separate cover and, in accordance with the City's purchasing policy, the selection of the firm was made based on the most qualified vendor rather than cost. All of the firms that responded to the Request for Proposal are capable of completing the job required. However, Krieger & Stewart, Inc. was chosen based on their comprehensive experience in domestic water well design and construction. Krieger & Stewart was able to identify several similar projects constructed for the City of Colton and other large water purveyors including agencies such as Eastern Municipal Water District and Desert Water Agency. Krieger & Stewart's design technique utilizes well drilling and testing prior to pump design completion. This conservative and well -organized method ensures the characteristics of the wells will be certain at the time of the pump design in order to maximize water production.
