Chillers & Chilled Water Pump Upgrades

The Anchor Bay School District is procuring chillers and chilled water pump upgrades across four elementary school facilities through an energy services performance contract managed by Centrix Energy Partners, LLC. The procurement involves the replacement of existing chillers and chilled water pumps with higher efficiency equipment at Lighthouse Elementary (51880 Washington Street, New Baltimore, Michigan 48047), Lottie Schmidt Elementary (33700 Hooker Road, New Baltimore, Michigan 48047), MacDonald Elementary (5201 County Line Road, Casco, Michigan 48064), and Maconce Elementary, along with replacement of a blower coil unit assembly at Maconce Elementary. Bidders must provide all labor, materials, equipment, technical supervision, and commissioning services necessary for complete system installation, testing, and integration with the existing Automated Logic building automation system via BACnet MS/TP protocol. The chilled water systems are designed to operate at 280 GPM with a supply temperature setpoint of 42 degrees Fahrenheit, incorporating dual circulation pumps with automatic failover capability, variable frequency controllers, direct digital control components, and current monitoring devices. Sealed bid proposals are due by June 11, 2026, at 1:00 p.m. at the District Administration Office in Casco, Michigan, with public bid opening and reading at that same time and location. A pre-bid walkthrough is scheduled for May 20, 2026, at 10:00 a.m., and the Notice to Proceed is scheduled for June 25, 2026, following the June 24, 2026, Board of Education meeting, with construction commencing by July 6, 2026, and substantial completion required by October 30, 2026, with functional performance testing and commissioning scheduled for spring 2027. Bidders must submit a 2.5 percent bid bond with proposals and demonstrate comparable experience with similar projects completed within the last five years, provide detailed project schedules, maintain comprehensive insurance coverage including $1,000,000 general liability per occurrence, comply with Michigan Prevailing Wage for State Projects Act rates effective February 13, 2024, obtain all required permits and licenses at no additional cost to the District, and provide one-year warranties on all mechanical installations from the date of substantial completion, along with a minimum of 24 hours of formal instruction to District personnel for equipment operation and maintenance.

The District has specified basis of design manufacturers including Daikin for chillers, Bell & Gossett for chilled water pumps, and ABB for variable frequency drives, with alternative manufacturers from Johnson Controls/York, Trane Technologies, Taco, Armstrong Fluid Technology, and Danfoss subject to owner approval, with substitution requests required seven days prior to the bid date. All bidders must provide sworn and notarized statements disclosing any familial relationships between firm owners or employees and the Superintendent or Board members, certify non-compliance with the Iran Economic Sanctions Act as defined by MCL 129.311, and submit Payment and Performance Bonds covering the full proposal amount along with certificates of Liability and Worker's Compensation Insurance. The chilled water systems must integrate with the existing Automated Logic building automation system and incorporate specified control components, DDC controllers, sensors, actuators, control valves, and 24-volt and 120-volt field wiring per design specifications prepared by Peter Basso Associates, Inc., with separate conduit systems required for voltage circuit separation. Subcontractors are required to provide written fair market value estimates for existing chiller equipment being replaced, with any realized value credited to the District through line-item cost deductions or trade-in allowances documented in proposal pricing, and complete responsibility for equipment disposition resting with the selected contractor following District approval. While specific contract award values are not disclosed in the procurement documents, the project encompasses a comprehensive energy services performance contract involving multiple school facilities and significant mechanical systems replacement, suggesting a substantial contract value commensurate with multi-building HVAC upgrade projects of this scope and complexity.
