This Addendum No. 001, dated August 31, 2026, amends the original drawings and specifications for the Taylor Schools Hoover Middle School MEP (Mechanical, Electrical, Plumbing) Upgrades project located at 27101 Beverly Road, Taylor, Michigan 48180, issued by The Collaborative on behalf of the Taylor School District. The project scope encompasses comprehensive HVAC system upgrades including the installation of new rooftop units (RTUs), air handling units (AHUs), heating hot water coils, exhaust fans, relief hoods, and associated ductwork and piping throughout the first floor and roof areas. Key clarifications provided in the addendum address structural support requirements, specifying that steel support is required only for pipe or duct openings larger than 28 inches in diameter, with Simpson Quick Frame systems to be used for all new RTU supports and exhaust fans exceeding 28 inches diameter. The addendum confirms this is a prevailing wage project and corrects the bid bond requirement from 10 percent to 5 percent. Significant drawing revisions documented include modifications to ceiling demolition and reflected ceiling plans to accommodate revised supply and return ductwork, RTU location shifts based on structural snow drift considerations, and adjustments to mechanical systems including changes to energy recovery unit controls and heating coil configurations across multiple building areas.

The addendum comprises four written pages and twenty updated drawings reflecting revisions across architectural, mechanical, and electrical disciplines. Notable changes include the addition of a service platform for RTU-3 under Alternate-2, relocation of RTU-2 per structural requirements, deletion of cooling functionality from AHU-2 in Alternate-2, and modifications to condensate piping and RTU service platform details on newly added sheet M5.01. All existing equipment must remain operational during construction, with coordination required between mechanical, structural, and other trades to ensure proper installation and sequencing. The project requires bidders to acknowledge receipt of this addendum in their bid forms, and all work must proceed in accordance with the contract documents, applicable codes including the 2021 Michigan Building Code and Michigan Mechanical Code, and the engineer's specifications.

TO ALL BIDDERS:

This addendum supplements and amends the original drawings and specifications, and shall be taken into account in preparing proposals, and shall become a part of the contract documents. Receipt of this Addendum must be acknowledged in the Bid Form.

GENERAL

Question:

Duct penetrations are assumed to have steel support due to size of ductwork penetrations. Can you confirm if we will need to add steel for the following it’s not clear so just looking for clarification if we need to add steel supports for the following. Pipe portals, Exhaust fans, & relief hoods.

Answer:

Only need steel support for pipe or duct openings larger than 28” in diameter. We have the Simpson

Quick frames detail (On the roof plan) to be used for any new RTU supports.

Question:

Confirm if we need to reinforce any joist?

Answer:

Use the Simpson quick frames system below each new unit and SA and RA ducts. Same for any exhaust fans that are greater than 28" diameter up blast.

Clarifications:

1. This is a prevailing wage project

2. A 5% bid bond is required, not a 10% as listed
