Window Replacement

BID DUE DATE: May 1, 2025 @ 2:00 pm

TO: All Contract Document Holders of Record.

This Addendum forms a part of the bidding and construction documents. This Addendum supersedes and supplements all portions of the original bidding and construction documents dated January 17, 2025, with which it conflicts. Please attach this Addendum to the Project Manual(s) in your possession.

ACKNOWLEDGE RECEIPT OF THIS ADDENDUM IN THE SPACE PROVIDED ON THE BID

FORM. FAILURE TO DO SO MAY SUBJECT BIDDER TO DISQUALIFICATION.

1. QUESTIONS/CLARIFICATIONS

a. Clarifications

i. Contractor to provide tempered glazing on lower sash of (2) windows in the Carpentry

Shop stairwell. See the plan page below for reference.

ii. Contractor to provide a SF unit cost for stucco repair/replacement and re-painting

(incidental damage to façade during demolition).

iii. Specification section 07 9200 – Joint Sealants, line item 2.5.B has been removed from the project. See specification section below for reference.

iv. Per specification section 01 1200 – Contract Summary, line item 1.04.A.1 and 1.04.A.2, the Contractor shall be responsible for all abatement activities as required by the Contract

Documents. Information regarding existing hazardous materials is provided in Section 00

3126 – Existing Hazardous Material Information. The Contractor shall retain a licensed abatement subcontractor to perform the required abatement work per Section 00 3126 –

Existing Hazardous Material Information.

v. See attached meeting minutes and sign-in sheet below from the pre-bid meeting held on

April 17th, 2025.

Q1. Can you advise on which windows openings will require abatement? The survey provided appears to show hazardous materials in a few areas, but not all openings were sampled, so it is unclear which specific locations need to be addressed by a licensed abatement contractor.

A1. All the windows in Appliance Shop have asbestos containing window glazing and caulking, and the concrete surrounding the windows contains lead-based paint. All the windows in the Powerhouse have asbestos containing windows (other than the vinyl replacements) and the metal frames contain lead-based paint (this will be removed with the asbestos) and the concrete surrounding the windows contains lead-based paint. All the wood window trims associated with the windows in the Carpentry

Shop contain lead-based paint, no asbestos. All the wood window trims in the Paint Shop, as well as the brick surrounding them, contain lead-based paint, no asbestos.

Q2. What are the parameters for patching, repairing, and painting the stucco finish at the door perimeter on plan page A-35 Elevation 1?

A2. The contractor shall patch, repair, and paint the stucco finish within a 12” diameter of the door frame.

Q3. Who do we contact if we would like to take an additional site visit?

A3. Contact Tony Kempker for any additional site visits. Tony can be reached at (319) 931-9460.
