Replace Roofs Building 69 and 139

Project No. 542-23-201, Solicitation 36C24426B0010

Amendment No. 002

Additional Contractor Questions and VA responses (bold).

Please provide a copy of the phase 1 asbestos survey/report (or any applicable hazardous materials report) covering the scope of work for this project. This can be found in the Design Narrative - Appendix DÂ

The taper drawing on sheet A-105 shows a Y-panel start at the roof drain with a starting thickness of 1½-inch (R-8.6). The taper drawing on sheet A-110 shows an X-panel start at the roof drain with a starting thickness of ½-inch (< R-3). This contradicts with Specification Section 07 22 00, paragraph 2.1.A.2 which requires an R-10 minimum (or 1¾-inch) at any location. Which taper should be provided, the ones shown in the plans, or that which is in the specifications? The tapered insulation layouts included in the drawings are provided to show intended slope of the finished roof. These do not include information about a base layer which will be required on each building to achieve the required R-values: minimum R-10 and overall average R-33 as required in the specification refer to section 072200 2.1 A.  Tapered insulation shop drawing submittal shall include evidence of calculated average R-value meeting this minimum requirement.

Please provide a typical roof system detail for the shingle assembly similar to that shown on Detail 2/A-503 for the low-slope assembly.

Where does the composite nail base specified in Section 07 22 00, paragraph 2.4.D get installed? Please specify the thickness required. This was taken from the VA.TIL specs we had left this in the specifications for the penthouse shingled roof. Â VA requires adherence with the specification.

For the skylight removal on Building 139, Details 2 & 3/S-104 appear to indicate that a new raised deck will be installed approximately 14-inches above the existing roof. This would create a base flashing condition. Sheet A-107 does not show this raised area. Will the new structural deck at the skylight removal be flush with the existing deck, or will it be raised? If raised, please provide details showing the roof flashing and termination conditions at this area. The design intent is for the roof deck infill to be placed on the existing curbs and be raised as shown in the detail on S104. This allows for the 6" cold form to be installed to support the new ceiling within these skylights. The flashing detail is similar to Detail 4 found on sheet A503.

Section 07 31 13, paragraph 2.1.A refers to Section 09 06 00 for the shingle Basis of Design. The 09 06 00 specification states the shingle size, shape, and manufacturer are to be selected. Please provide a basis of design for the shingles. Refer to section 073113 2.2, for requirements.

Will snow guards be required on the shingle roof? There are currently snow guards installed in the shingle roof only above the penthouse doorway but not the entire perimeter. VA requires to maintain snow guards in that location.  These are listed in 073113 2.7

Section 07 52 16.11, paragraph 2.3.C.2: are bio-based SBS modified bitumen products applicable to this project? Yes, cold applied membrane adhesives are required to have bio-based content. Refer to 075216 2.5 C and D

Referring to Detail 3/A-503, the replacement fascia appears to be a unique custom prefabricated item. Please provide a manufacturer basis of design for this fascia. Include material type and size/thickness. Also, please provide attachment requirements and details. Match existing adjacent trim in materiality and method of connection.Â

Referring to Detail 3/A-503, the shingles and roof felt appear to be installed over some sort of insulation and a wood starter block. Is this insulation currently in-place? What substrate will the shingles be nailed to? Nail base (refer to question 4). Note that this is not a vented product consider a vented nailboard (see Hunter Cool-vent as an example).Â

Refer to the phasing plan for Building 139 (Sheet A-108). Phases 03, 04, and 05 entail installing and flashing new HVAC units prior to installing the new roof assembly under phases 06, 07, and 08. The new roofing and flashing assemblies (SBS modified bitumen) are incompatible with the existing EPDM assemblies. The new flashing installed during phases 03, 04, and 05 cannot be properly sealed to the existing EPDM. Can Phases 03, 04, and 05 be combined with phases 06, 07, and 08? If not, please provide tie-in details between the new modified system and the existing EPDM system. The specified final membrane flashings for the modified bitumen roof system should be installed during phase 06, 07 and 08. Install temporary watertight seals compatible with existing EPDM roofing for work in phases 03, 04 and 05. Unless otherwise noted, prep surrounding existing roofing with membrane cleaner and primer, and install EPDM membrane patch material (typical peel and stick patch roll with pressure sensitive adhesive backing and release liner) to make curbs weathertight until reroofing phase work begins.

Refer to the phasing plan for Building 139 (Sheet A-108). Which trade provides and installs the penetration housings listed under Phases 03, 04, and 05? Typically a mechanical contractor provides/installs and the roofing contractor flashes to the roof, but decision falls on prime contractor and specifications.

Advise what are the ICRA Levels in the areas below the roof level where items are to be removed and decking repairs are required. For example, where skylights and penetrations are to be removed. Refer to Appendix E of the Design Narrative Â

Is the use of temporary plastic wall panels (such as STARC panels) acceptable to meet ICRA requirements? ICRA barrier approval will come after formal submittal process to awarded contractor.

Roof plans indicate providing roof curb extensions. Please advise if sizes of curbs or model numbers of existing equipment can be provided. Please clarify required height of extension. Refer to General Notes on M101. Additional info requested was "if possible" - I do not have that information at this minute, and I have not yet received any further detail. But the question regarding the curbs is covered in the General Notes. If I get anything further today I will send it but this response should be satisfactory.Â

Confirm there are no existing asbestos or hazardous materials to be removed. This can be found in the Design Narrative - Appendix DÂ

Amendment No. 001

Contractor Questions and VA Responses in bold Part 1.

Include Site Visit Contractor sign-in sheet dated 6/10/2026.

Bids due July 9, 2026, at 12:00 PM EDT

Provide design narrative.

Will piping riser need replaced below roof drain? Not indicated on drawings. Or just the roof drain itself? Per drawings: only roof drains.

Will there be any equipment replaced? Or just reusing existing? Both.

Designated laydown area location? Laydown is usually discussed after project award.

Will temporary equipment be needed? Not likely.

What is the pipe size for the roof drains? Contractor to verify.

Please provide a copy of the phase 1 asbestos survey/report (or any applicable hazardous materials report) covering the scope of work for this project. See attached design narrative. If an asbestos report is not available, please advise whether the Contract Documents will allow for a Unit Price Allowance to address potential asbestos abatement activities. Not Applicable. Contract will be firm fixed price.

The solicitation states that the Contractor is to repair damage due to leaks and age as needed and required for Building 139 s roof structure. As these appear to be unforeseen conditions, please confirm if a lump sum Allowance, or a Unit Price Allowance would be able for bidders to provide to price this work. If so, please provide details on how to price this work. Conditions are available in attached design narrative. No unit price allowance or allowance will be used.

Please confirm if there are any associated warranties with the existing roof structures along with any information of existing roof materials. None currently on record.

Has a roof condition survey or core cuts been performed? Yes. If so, can we have the report and photos? See design narrative for report and photos.

Please confirm if Note 2/A102 is for only (1) glass panel or multiple. If so, please provide the quantity. Drawing A102 Note 2 show 1 panel. Contractor to verify.

On building 69, Is the Natatorium part of the scope of work? It does not currently have lightning protection. To meet UL standards, it needs lightning protection. Do they want lightning protection installed as part of this project? Only portions as indicated in the drawings. Mostly resealing, redirecting drainage and replacing a pane of glass. Again, this is all indicated clearly in the bid documents. Lighting protection is shown to be replaced as indicated on the drawings and as directed by the VAMC.

On building 139, Is the masonry coping being replaced with metal coping? Not replaced covered with metal coping see detail A 502-11

Do asbestos and lead surveys/reports currently exist for buildings 69 & 139? If so, can the VA publish them for our review? Please review design narrative.

Since there is no asbestos section in the specifications, we assume there is no abatement required under this contract, only an investigation per the Project Understanding section of the solicitation. Is this accurate? Correct.

During the freezer condenser work on building 139, is the contractor responsible to develop the phasing plan only, and not assist with the relocation of food items? That is correct. Contractor will not handle VA food stuffs.

Do the temporary safety railings atop building 139 get demolished and put back after the roof is completed? See note on drawing AD-102 and A-107.

Do the temporary safety railings around the existing skylights atop Building 139 get demolished, or does the VA want to keep them? Some will need to be reused in accordance with the note on A-107 any remaining will be returned to VA.

For the tree removal noted on AD-102, does the VA want the stumps ground or removed as well? Yes. Please remove stumps.

Section 07 22 00, paragraph 2.2.B.3: are bio-based insulation products applicable to this project? Possibly. Contractor will need to show it conforms to specification.

During the scheduled site visit we were not allowed access to the roof of Building 69 to investigate existing conditions. The reasoning being that access would have to be through an extension ladder set-up on the exterior of the building and that fall protection would be needed. OSHA Section 1926.500(a)(1) allows inspectors to be exempted from the fall protection requirements when performing an inspection before or after the performance of work. This includes verification inspections as we tried to perform during the site visit. We request a consecutive 3-hour period where two of our inspectors can investigate the existing conditions of this project on the rooftop. While OSHA guidelines provide this exemption, we do not require OSHA certification for site visits. No additional site visits will take place. Please see design narrative for current conditions of both roofs.

If a formal inspection time will not be provided, please comment how discrepancies between plans and actual field conditions will be handled. Any discrepancies from plans and conditions provided by the VA will be handled in post-award.

Will the sign-in sheet from site visit be available in addendum? See attached.

Please clarify if a superintendent can be a dual hat to cover the requirements of SSHO? No. See Spec 013526 1.9

If no to the question above, will the SSHO need to be full-time for this project? SSHO will need to maintain full time presence on jobsite as shown in Spec 013526 1.9

Please clarify if a superintendent can be a dual hat to cover the requirements of QA/QC? Yes. See spec 014500 3.4 B.

If no to the question above, will the QA/QC need to be full time for this project? N/A

Can a superintendent be a triple hat to cover the requirements of SSHO and QA/QC? No.

Please confirm if tax should be included in our proposal? Bids should be inclusive of all allowable contractor costs. Contract is firm fixed price.

Will shutdowns be required to be done during off hours or weekends? There is a strong possibility of that occurring.

Are there any areas in either buildings that require advanced notice of work activity or vibration control? Yes. Building 69 contains audiology, recreation therapy and physical therapy. Basically the whole building. Building 139 is the patient dining hall. Areas over patient serving and dining would pose greatest concern.

Is there a particular vendor or contractor currently servicing and maintaining the Building Automation System or Temperature Controls System? CM3 holds the contract for this.

To allow sufficient time to review responses and prepare our bid we kindly request that you please extend the bid date. Bid date extended one week to 7/9/2026.

Will both construction areas share a laydown area? Please indicate the laydown areas for both Building 69 and Building 139 on Staging Plan drawing sheets A-001 A-002. Laydown areas will be agreed upon by VA and contractor after contract award.

Can both buildings be worked on concurrently? Yes.

Please confirm the bid package requirements for submission (ex. SF 1442, Acknowledgment of Amendments, Completed Limitations on Subcontracting, etc.) Please see submission requirements outlined in the solicitation for bid response.
