This is an Addendum No. 1 to the contract documents for the Baraga Correctional Facility Housing Unit 8 Roof Replacement project issued by Michigan DTMB (Department of Technology, Management & Budget) in coordination with the Department of Corrections. The project involves the replacement of standing-seam metal roof panels on Housing Unit 8, with a bid date of Wednesday, December 4, 2024. The addendum incorporates clarifications and modifications to the original contract documents dated September 30, 2024, including the attachment of a pre-bid meeting attendance sheet and reference photos of the building. Key product specifications include approval of MP-175 metal panel systems manufactured by a Cincinnati, OH-based supplier, with one-piece fixed clips to accommodate thermal movement made from 16-gauge zinc-coated or aluminum-zinc alloy-coated steel, 18-inch panel coverage, and 1.5-inch nominal panel height. Special working conditions require daily cleaning with a magnet as outlined in Appendix II, Item 11.b.

The addendum revises several technical drawings and specifications to ensure consistency across contract documents. Revisions include corrections to the A-101 Housing Unit 8 Roof Plan note references, modifications to Details 2 and 4 on drawing A-301 to reference 1.5-inch standing seams rather than 2-inch seams, and the addition of a new E-101A Partial Electrical Floor Plan sheet that identifies interior ceiling scope for electrical work items. These changes clarify the technical requirements for bidders and ensure alignment between the project manual specifications and the corresponding construction drawings.
