This is Addendum No. 2 to the bidding documents for an Intermediate School Chiller Replacement project by Edwardsburg Public Schools located in Edwardsburg, Michigan. The project scope includes replacement of the existing chiller and two water heaters at the intermediate school facility. The pre-bid meeting was held on November 30, 2020, at 2:00 PM, with attendance no longer mandatory but requiring bidders to schedule separate site visits with CARMI Design Group if not attending. The question deadline was December 1, 2020, at 5:00 PM, with bids due on Friday, December 4, 2020, at 2:00 PM. Contract award was scheduled for Monday, December 14, 2020, at 7:00 PM. Construction work must be completed by April 9, 2021, with product procurement to begin immediately upon contract award. The addendum includes significant technical clarifications and modifications to the original bidding documents dated November 18, 2020, including revised chiller specifications with aluminum micro-channel condenser coils, modified cooling capacity requirements (1,782.0 MBH at 95°F ambient and 10.29 EER minimum), and detailed mechanical system notes regarding roof penetrations, refrigerant piping sizing, chiller placement on concrete pads with neoprene supports, and interlock requirements between the chiller's refrigerant monitoring system and existing boilers.

Bidders were required to submit bid bonds equal to 5 percent of the bid amount, along with payment and performance bonds. The project requires a single contract with base bid and voluntary alternates, and all bidders must acknowledge receipt of the addendum with their bids. The contract will be based on AIA documents to be generated by CARMI Design Group, with the project subject to State of Michigan plan review. Fourteen contractors were identified as plan holders, including mechanical, electrical, and HVAC firms from Indiana and Michigan. Additional clarifications addressed in the addendum include contractor responsibility for temporary toilet facilities, coordination with school administration regarding construction noise that could affect students, asphalt protection and restoration if the chiller is craned from adjacent pavement, manufacturer-certified roof work to maintain Fibertite roof warranty, and confirmation of chilled water chemical pot feeder capacity to match existing equipment specifications. Addendum No. 3 was anticipated to be released on December 3, 2020, with further clarifications on refrigerant salvaging, equipment recycling, and a revised bid form.
