Item No: 7M Meeting Date: May 23, 2011 Type of Business: Council Business Administrator Review: ____ City of Mounds View Staff Report To: Honorable Mayor and City Council From: Nick DeBar, Public Works Director Item Title/Subject: Resolution 7796, Approving a Construction Contract with Muska Electric Company for the 2011 Electrical Modifications for Well No. 2 Motor Conversion Project Background: Municipal Well No. 2 was constructed in August 1962 and is located within the Public Works Facility at 2466 Bronson Drive. Well No. 2 was powered by a natural gas engine (all other wells have electric motors) and is in the process of begin converted to electric motor power. This conversion was necessary due to the erratic behavior of the 35+ year old used gas engine that was causing the water distribution system to work under a vulnerable state of spiked pressure. A new 200-HP electric motor was installed as part of the well rehabilitation last year. The remaining work now left to do is associated with electrical modifications to the well house for accommodating the new motor and associated control system. Upon completion, Well No. 2 will be used interchangeably with Well No. 1, each delivering approximately 10% of the City’s’ water supply. Well No. 2 is currently off-line pending completion of the electrical modifications. Discussion: Last July, the City Council approved the hiring of Bolton & Menk, Inc., an engineering consulting firm, for engineering analysis and plan and specification preparation for the electrical modifications (Res. 7644). The work includes the following: 1. Electrical & mechanical demolition, disconnection, and removals; 2. Structural demolition, removal, & disposal; repair concrete floor slab & patch walls; 3. Furnish & install new magnetic flow meter & associated piping modifications; 4. Construct new main electrical service & coordinate with Xcel Energy; 5. Furnish & install switchgear, panel boards, circuit breakers, switches, raceways, wiring, & all associated work; 6. Furnish & install variable frequency drive & associated work; start-up & training; 7. Furnish & install new SCADA panel & antenna; coordinate with vendor. Request for quotes were sent to five qualified electrical contractors and three quote proposals were received on May 19, 2011. The quotes ranged from $55,400 to $72,450 with the low quote submitted by Muska Electric Company of Roseville, Minnesota. All quotes were below the engineer’s estimate of $75,000. Bolton & Menk has submitted an hourly fee estimate not to exceed $5,000 to perform engineering services associated with the construction phase. Services include reviewing shop drawings, submittals and O&M manuals; part-time inspection at various stages of the project; provide technical support; perform final inspection and witness start-up; and other miscellaneous and related work.
