This is an Addendum No. 3 to bidding documents for an Intermediate School Chiller Replacement project issued by Edwardsburg Public Schools located in Edwardsburg, Michigan. The project involves the replacement of an air-cooled chiller system with a Quantech QTC3150THE grade-mounted chiller with remote interior bundle, along with associated chilled water distribution equipment and controls. The chiller has a capacity of 1,782 MBH with 10.29 EER efficiency and will serve a 390 GPM chilled water circulation system. The original bid submission deadline of November 18, 2020 was extended to Wednesday, December 9, 2020 at 3:00 PM due to COVID-19 challenges. Bidders are required to make themselves available for post-bid interviews on December 10, 2020 to allow for award recommendation by December 11, 2020 at 1:00 PM. The addendum requires acknowledgment of receipt and includes a revised bid form and revised drawing sheet M3.0 reflecting chiller capacity revisions from Addendum No. 2. Bidders must have visited the site prior to submission to fully understand field conditions and the existing mechanical systems.

The addendum establishes environmental and equipment handling requirements, including responsible recycling of removed equipment with required documentation and the salvage and recovery of the existing chiller's refrigerant for storage in appropriate containers for future reuse at the owner's other facilities. No pricing information is provided in this addendum document. Contractors are responsible for coordinating the phasing of work to maintain facility operations, scheduling work to minimize downtime, and obtaining written approval for any structural support modifications. All bid submissions must include a bid bond, list of warranted projects, summary schedule, Iran Economic Sanctions Act Certification, and Familial Disclosure Statement. The project manual was originally dated November 18, 2020, with this addendum issued December 3, 2020.
