Buildings 149 and 256 both have existing roof structures that are sloped. Please refer to drawings AD501 and AD502.

Detail 1/AD501 calls out “Exist sloped wood roof structure” and detail 1/AD502 calls out “Exist sloped steel roof structure.”

Additional slope at the roof overhangs on building 256 is shown on sheet AD502.

In addition, the arrow symbols on the various roof plans differentiate “roof deck slope” from “tapered insulation slope” as defined on sheet G‐002.

17 Is the EPDM to be black or white? Normally I would assume standard black but we just did a 90 mil white EPDM job on an adjacent building out there? The specs call for a Class A roof which will require gypsum over the deck first which the specs doesn’t spell out and the drawings don’t show.

PVC or EPDM membrane color will be White. Refer to manufacturer's recommendations for achieving class A roof system.

For example, a class A roof system can be achieved by providing 1/2" DensDeck Prime coverboard.

Refer to summary on page 1 ‐ the material tested at Building 149 was not classified as ACM in accordance with NH regulations.

Update 04‐ 02/01/2021

19 Solar collector and wanted to ask the question. It says to provide temporary support during construction. This tells me that it needs to stay up on the roof. I am concerned that it will be broken or blown off by high winds if it’s left up on the roof and not bolted down to anything. Would it be ok to take down off the roof and support on the ground somewhere during construction? Im not quite sure if this thing is supposed to remain operational during construction or not, it says to remove the pipe penetrations, but not the pipes.

The Contractor can remove the solar hot water system after the function check and place it on the ground during the construction project and reinstall it when the roof has been installed and inspected by the contracting officer.
