PSA with Kredit Electric for the Bozeman Hilltop Tank Mixer Addition Project Commission Memorandum REPORT TO: Honorable Mayor and City Commission FROM: Brian Heaston, Senior Engineer SUBJECT: Authorize the City Manager to Sign a Professional Services Agreement with Kredit Electric, Inc. for the Bozeman Hilltop Tank Mixer Addition Project. MEETING DATE: April 8, 2019 AGENDA ITEM TYPE: Consent RECOMMENDATION: Authorize the City Manager to Sign a Professional Services Agreement with Kredit Electric, Inc. for the Bozeman Hilltop Tank Mixer Addition Project. BACKGROUND: The Bozeman Hilltop Tank, built in 1985 and located on Kenyon Drive, provides 2 million gallons of potable water storage capacity and is an integral component of the City’s municipal water distribution infrastructure. The tank is built of steel applied with special coatings systems on both the interior and exterior to preserve the structural integrity and increase longevity of the tank. The tank is susceptible to the formation of ice during cold weather periods. Ice formed within the tank floats on the surface of the water stored in the tank. Tank levels fluctuate over the course of a 24 hour period which causes ice to scour the interior coating system reducing the coating’s efficacy due to reduction in thickness. Over time, ice will the scour the coating system down to bare steel. The original interior and exterior coating systems of the tank were replaced with new coatings in 2007. At that time, the interior upper quarter of the tank exhibited severe ice scour down to bare steel. Water quality of stored water in the tank deteriorates in the spring when the ice cap melts producing changes in thermal stratification that causes water in the tank to ‘flip’. The flipping of water induces a temporary yet noticeable difference in the taste/color/odor profile of water stored in the tank. The water remains safe to drink during these flipping periods as it continues to meet all water quality standards of the federal Safe Drinking Water Act. City water treatment plant operators generally experience water quality complaints on an annual basis from customers in proximity to the tank when it flips. The attached Professional Services Agreement (PSA will place Kredit Electric, Inc. under contract to perform electrical work necessary to install a mechanical mixing unit within the tank. The mixer adds energy to the water stored in the tank at a level sufficient to form continuous turbulent currents that prevent the formation of an ice cap in the tank. Installation of mixers in potable water storage tanks has been shown to improve water quality due to elimination of 86 thermal stratification within the tank. The mixer installation will enhance the resiliency of the City’s water distribution system and hopefully stem future water quality complaints. Plans and specifications for the mixer installation were prepared by AE2S under its water treatment plant on-call engineering contract. The mixer unit itself has been separately purchased by the water treatment plant and is currently awaiting installation. AE2S plans/specs were shopped to three local electrical contractors to acquire price quotes for the installation. Kredit Electric submitted the low quote and reference checks were positive. The water treatment plant has arranged for Liquid Engineering out of Billings to place the mixer unit within the tank itself utilizing divers. The divers will also conduct an inspection of the interior of the tank and prepare a report documenting findings. Kredit Electric will wire up the mixer once the divers have it placed. FISCAL EFFECTS: The adopted FY19 Water Fund CIP contains project W78, funded at $130,000, for the Hilltop Tank Inspection and Mixing System project. This budget is sufficient to cover costs for AE2S design services ($21,300), mixer unit purchase ($39,930), and (Kredit Electric electrical installation ($8,990), and Liquid Engineering diver placement of the mixer and inspection of the tank interior (~ $5,000). ALTERNATIVES: As suggested by the Commission.
