AMENDMENT NO. 6 CONTRACTOR QUESTIONS AND CLARIFICATION

1. Roof membrane is called out in the specs as being 60-mil, but it says fabric backed, which would be a 115-mil fleeceback membrane. Please verify that a fleecebacked membrane is required or if we can install standard 60-mil white TPO.

Response: Standard 60-mil white is acceptable; fabric backed is not required for a new roof. See revised specification Section 07 54 23

THERMOPLASTIC POLYOLEFIN (TPO) ROOFING.

2. Roofing spec calls for 5/8” coverboard, roof details show 5/8” substrate board and ½” coverboard, please verify correct assembly.

Response: Install cover board and substrate according to roof details on drawings; ½” cover board above insulation under roofing and 5/8” substrate under insulation. See revised specification Section 07 22 00-

ROOF AND DECK INSULATION.

3. Roofing spec does not list a vapor barrier; however, one is called out in the drawings. Per the warranty requirements vapor barrier is not required, but please verify if one is to be included in the system.

Response: Vapor barrier is required. See revised specification Section

07 22 00-ROOF AND DECK INSULATION.

4. Due to some inconsistencies in the door schedule, some assumptions were made on the hardware sets. Set 1 cannot use auto flush bolts as the doors are fire rated. Set 2 cannot use push/pull as rating requires it to be self-latching, and auto closing. Set 7 was missing from the specs. Please review door hardware.

Response: See revised specification 08 71 00 DOOR HARDWARE Amendment

No. 5 issued in Amendment 05.
