W9127N23Q0024 – Questions & Answers

Q1: Normal course of business for this type of project is a delivery requirement after final approvals have been received by the door contractor. Is this acceptable on this project?

A1: Updated from “20 wks after date of award” to “20 wks after final approvals have been received by the contractor.”

Q2: Para 2.1 of the [prior] specification calls for “The door shall be constructed of structural steel, structural tubes or channel shapes and follow ASTM A992 Standard Specification for Structural Steel

Shapes with Aluminum skins.” The Electric Door Man 1955 drawings are Aluminum Structural Framing with Aluminum skins…

A2: Para 2.1 of the specification has been updated as follows:

2.1 DOOR SECTIONS

Provide the door panel preassembled and ready for installation. The door shall be constructed of structural aluminum, structural tubes or channel shapes and follow ASTM B221‐21 Standard

Specification for Structural Aluminum Shapes. Provide intermediate horizontal or vertical stiffeners so the maximum unsupported area of sheet is 20 square feet. Corners and intersections of frame members must be welded and ground smooth on exposed surfaces. Welds must develop the full strength of frame. Each door section shall be fully clad with aluminum sheet. The door sections shall be limited to 1/8” of inside to outside movement.

Q3: Also in reference to Para. 2.1: The door on the Electric Door‐Man 1955 drawings was shipped in two pieces due to the 12’ x 14’ size of the door panel and the ease of shipping, cost of the shipment and crating required per the specification. This does not seem to make sense for shipping, handling, installation, and of course overall cost of the project.

A3: We are requiring the door to be shipped and delivered in one piece. We would like to avoid the costs of welding and assembling at the site, the credential generation for on‐site work, the Contractor oversight at the site, and the on‐site labor requirements of the Contractor. We realize the shipping costs will be higher.
