6 Specification Section 01 00 00, Paragraph 1.3.A (Statement of Bid Items): Is a new lightning protection system required for the new roof?

Lightning protection is not within the scope of this project.

7 Specification Section 07 53 23 (EPDM Roofing), Paragraph 2.3.A (Products- General): Are there other manufacturers of equivalent thickness that would be acceptable for the EPDM roofing? (e.g., Carlisle or Versico).

Any equivalent or better product is acceptable.

8 Is the entire existing roof system to be torn down to deck, deck inspected and new insulation, and EPDM system to be installed?

The membrane and any cover is required to be removed to deck, the deck inspected and repaired if necessary, and new coverboard/membrane installed per the detail on sheet A103, detail 1.

9 Or is only the membrane to be removed the insulation to be replaced only if wet or damaged?

Insulation is only to be removed if wet or damaged. Please refer to RFI question #33 as well.

10 There is no spec for a cover board to be installed. In the drawings below it appears that the plan is to keep current insulation and install 3/8 inch dens deck cover board. Are we correct in this assumption?

Yes

11 Is the gypsum board to be mechanically fastened?

Yes

12 Is the EPDM system to be adhered? Yes 13 25-year warranty is called out in the specifications are we able to utilize another manufacturer if we can meet the 90 mil EPDM and 25-year warranty requirement.

Any equivalent or better product is acceptable.

14 What size gutter is to be installed? 5” Type ‘K’ Seamless Aluminum, 4” aluminum downspouts 15 What type of roof deck on the building? Current roof decking is suspected to be 3/4” pressure-treated plywood, but it is the contractors responsibility to field verify and replace in kind. See drawing sheet A103, detail 1.

16 What is the thickness of the existing insulation?

Current insulation is R-30 mineral wool w/ cont. vapor barrier stapled to joists. ASTM E 84 moisture resistant, flame resistant and mold resistant.

17 Is the roof deck sloped or is tapered insulation required?

Please refer to drawings. This is a low slope (1/2" in 12”) EPDM roof.

18 What is the thickness of new insulation? Current insulation is R-30 mineral wool w/ cont. vapor barrier stapled to joists. ASTM E 84 moisture resistant, flame resistant and mold resistant.

19 Does the new roof require a cover board or vapor barrier?

See drawing sheet A103, detail 1. Current insulation is R-30 mineral wool w/ cont. vapor barrier stapled to joists. ASTM E 84 moisture resistant, flame resistant and mold resistant.

20 Please confirm that the new metal is to be aluminum.

Yes, aluminum gutters, downspouts and any facia.

21 Please confirm that gutters and downspouts are to be removed for reinstallation.

No, provide new gutters and downspouts per drawings.

22 Please confirm is this work is just for the replacement of 1300 SF of roofing and anything else has to be perform?, since the government estimate is between $250K - $500K When is the expected day to start?

The contractor is required to replace roughly 1,300SF of roofing, all gutters, downspouts, facia as necessary, repair/replace water damaged roof decking/insulation, and provide new cover board.

23 confirm if the deck replacement is limited to 200 SF?

Please provide this as a deduct. If not required, it will be deducted from the contract. If more is required a change order is appropriate.

24 do you need any carpentry to be replace, as rafters, beams, struts, etc?

No, this is not expected and not within scope.

25 Is Procore Photo Tools (Map, Timeline, Albums) acceptable for photo documentation?

Yes

26 Can the Site Superintendent and SSHO dual hat ?

Yes

Yes, this is acceptable

29 How close can a boom truck be placed next to the building for placing materials?

Or should we plan to use a crane for longer lift?

A boom truck or other machinery is permitted as close to the building as terrain allows.

30 Please confirm requirement for Portable restrooms.

The VA will not provide restrooms to contractor; thus alternative arrangements must be made by the contractor.

31 Specification Section 01 00 00, 1.3.a calls for Alternate 1 but it is not indicated on the Price Schedule, is it required?

Yes, ALTERNATE NO. 1 is required.

32 If Alternate 1 is required, please specify roof decking material and thickness required so we may provide accurate pricing.

Current roof decking is suspected to be 3/4” pressure-treated plywood, but it is the contractors responsibility to field verify and replace in kind.

33 Drawing A102 notes ‘Ex. Insulation replace any Damaged in Kind’. This is difficult to quantify especially if the roof is currently leaking. Manufacturer will likely require all insulation be replaced to maintain a warranty. Please clarify this requirement for fair and equitable bidding.

If replacement of all insulation is required by the manufacturer to maintain warranty, then this must be included, however, it is up to the contractor’s discretion on how this is to be handle/bid.

34 Drawing A101 doesn’t indicate any roof penetrations. Since we weren’t able to get on the roof please provide quantity, type and size of roof penetrations and/or photos.
