IFB # 36C25722B0039 – Amendment # A00004

RFI #Pre-Bid RFI #1 — Asbestos Requirement Current Status: Resolved Description: There is a specification for the abatement for this project however the spec given does not have quantities in it. After reviewing Asbestos survey report, it appears that comprehensive survey report would tend to indicate that it doesn’t need abatement for pipe fittings or insulation. Can you please confirm this. If abatement required for this project, then provide us allowance to carry in our bid.

Comments:

it is my understanding that this project does not require any asbestos abatement due to the construction year of the building. However, I cannot say that there is no asbestos in the areas of work. The contractor was supplied with an asbestos report for the building and should use that as their basis for providing any allowances. Any allowances for abatement shall be clearly identified in their bids.

RFI #Pre-Bid RFI #2 — Valve Count Current Status: Resolved Description: Yesterday it was mentioned in the walk through that a valve count would be provided by the Engineer. Haven’t seen the valve count? The engineer said that they would provide the individual valve count.

The PRV schedule only reflects the PRV valve count. Not the individual valve count that is reflected on each page of the plans.

Comments:

** Attached is the updated valve quantity schedule. - Mark McComas
