Addendum No. 002 MSTB, FAA-OKC Work Order 6973GH-22-F-00856 Issued: August 1, 2023

Addendum No. 002 forms a part of the Contract Documents and modifies the original bid documents. Items in this Addendum take precedence over the original documents. Addendum No. 002 consists of the following:

General Information:

The purpose of the Addendum is to respond to Bidders questions and revise the construction documents in response.

Revisions are as follows:

1) Drawing revisions to indicate PEMB Batt roof insulation system noted in Specification

Section 07.21.16.

2) Revised Specification Section 13.34.19 – Metal Building Systems to identify roof and wall metal panels basis of design and delete remove roof ventilators accessory.

3) Bid Questions with responses.

Drawings:

1) Refer to attached Sheet A.501. Revisions to this sheet are the wall hatch designating the foam insulation. This sheet replaces A.501 in the original Construction Documents. This is a new sheet that replaces, in its entirety, the original sheet in the Construction Documents.

2) Refer to attached Sheet A.502. Revisions to this sheet include noting the PEMB roof insulation per spec section 07.21.16. This sheet replaces A.502 in the original Construction Documents. This is a new sheet that replaces, in its entirety, the original sheet in the Construction Documents.

3) Refer to attached Sheet A.702, Revisions to this sheet include noting the PEMB roof insulation per spec section 07.21.16 and revising the details to not show foam insulation on the roof deck. This sheet replaces A.702 in the original Construction Documents. This is a new sheet that replaces, in its entirety, the original sheet in the Construction Documents.

Specifications:

1) Refer to attached specification section 13.34.19 – Metal Building systems. Revisions include identifying basis of design for the roof and wall panels and deletion of roof ventilators in the accessories section. The Section replaces in its entirety the original specification section in the Construction Documents.

Bid Documents:

None.
