CNCC FY24-001 - Addendum 2.pdf

Addendum #2 August 22nd, 2023

CNCC FY23-010

Academic Building Roof Repair, Recover

Addendum #2

Questions/Answers:

1. We are wondering if we would be able to substitute the EPDM membrane for TPO and bid TPO on this project?

a. Answer: CNCC does not anticipate using TPO.

2. Over the finished wood overhang along the front of both sections of roofing about 6 foot out, there is existing material that is glued directly to the plywood decking that appears to be directly over the finished wood planking exposed on the soffit. To install the required fire rated board, the screws for attachment must extend ¾” beyond the substrate being attached to, laving screws sticking out of the soffit. I recommend removing the material over this area and fully adhering the fire board to the decking.

This will add a bit of cost but is necessary to complete properly. There is also some positive pressure causing ballooning on a large HVAC unit that will need to be addressed as well.

a. Answer: Based on roof coring previously performed, the subject soffit area consists of a 2” thick tongue and groove decking with an adhered plywood above it. Contractor will be responsible for providing mechanical attachment that will not penetrate the underneath side of exposed tongue and groove decking at soffits.

Mechanical attachment will be required to penetrate tongue and groove decking minimum 1” depth. See forthcoming Addendum #01 for additional information.
