Questions and Answers 12/08/2025

Project Title: Zuni Roof Replacement and Fall Protection Construction, AQ22ZS004 Solicitation #: 75H70126R00007

Below are the questions received in response to this solicitation and their respective answers:

1. Can we submit an alternate solution to the one requested in the RFP?

Similar question: There are a few other attachment options that we can limit the amount of adhesive needed. It could help save costs on materials and labor. Is there any interest in looking into different or additional attachment options?

Answer: You may propose this alternative system as part of your bid and the Government may then decide to do a deeper assessment if yours is the lowest offer being evaluated; remember that this is a LPTA solicitation. In your offer, I suggest you address the following questions:

- Is this product fully compatible?

- What are the vapor and off-gassing implications of product(s) with regard to infiltration into the facility?

- Are there multiple products such as cleaner, primer, coating, perhaps others for repairs prior to coating?

- 4. What is the warranty available for this particular installation? Make sure the warranty is stated clearly.

2. Past Performance – Teaming/Subcontractors. The solicitation states that teaming proposals must clearly identify each firm’s role and level of participation.

Question:

Will the Government allow relevant past performance from a major subcontractor or teaming partner, specifically for specialty trade work such as roofing, to be submitted and evaluated as part of the Offeror’s proposal?

Answer: Refer to M.2, Factor 2. Notice that this RFP will use a LPTA source selection, so the past performance evaluation will be rated as Acceptable/Unacceptable. Ensure the past performance record reflects how the past performance record of the proposed organization applies to this project.

3. Teaming Documentation Requirement. The solicitation indicates that “teaming proposals shall clearly identify the roles and level of participation of each firm.”

Question:

Does the Government require a signed teaming agreement (or letter of commitment) to be submitted with the proposal, or is identifying the proposed teaming structure and roles within the technical proposal sufficient?

Answer: Refer to L.8,Factor 3, Joint Venture Agreement (2) for signature requirements. and to SBA Mentor – Protégé Agreement for SBA approval requirements.

4. Key Personnel – Superintendent, SSHO, and Quality Control Manager Roles. The solicitation outlines the requirements for the Job Site Superintendent, SSHO, and Quality ControlManager.

Question:

Will the Government allow one individual to serve in more than one key role (e.g., Superintendent also serving as SSHO and/or Quality Control Manager), or does the Government require these positions to be filled by separate personnel?

Answer: Refer to M.2, Factor 1. Ensure your technical approach is appropriate for this project.

5. The plans show a tear-off leaving the Cementous lightweight concrete topping in place and installing the roof system over the top. The spec book calls for a tear-off down to the metal deck.

From what I understand, the metal deck sits below the concrete deck.

Do I figure to tear off down to the metal deck?

Answer: No, lightweight topping to remain per drawings.

6. Are there any requirements to utilize local labor?

Answer: No.

7. Is a bid bond required?

Answer: Refer to L.3. Yes.

8. Should our bid include gross receipts tax?

Answer: Refer to B.2 and L.8. Additionally, perform a search for the term “tax” throughout the RFP for additional tax considerations. Yes, taxes shall be included as part of your price proposal.

9. The bid is due on 12-2-25. When do you expect to award the project?

Similar Question: When does the agency plan to award the project as weather conditions can contribute to the 180 days of POP?

Answer: Refer to block 13.d of the SF-1442. The Government expects to award the project within 60 days of the FRP close date.

10. When is the first mobilization of work to commence?

Answer: Refer to F.2. The notice to proceed (NTP) date will be negotiated after award.

11. Is the building structurally sloped? The plans require a ¼” slope; however, the assembly does not specify any tapered materials.

Similar Question: I’m reaching out to confirm that the Concrete deck itself is sloped? The Drainage plan looks like it could be a full taper but the description specs seem to call just for flat stock and crickets.

Answer: The structure and metal deck are level. Existing roof slope is provided by the lightweight concrete topping. Tapered materials may be required to achieve specified slopes.

12. Can you confirm the following scope/assembly

a. Section 070150, section 3.2.A refers to tear off down to the metal deck. In section 075400-6section 3.2.D the spec book calls to repair holes and deficiencies in the lightweight concrete deck. Please clarify.

Answer: Lightweight topping on metal deck is to remain. Existing topping to be repaired if damaged during tear-off.

b. Section 075400 section 1.1.A-2 refers to an adhered ½” underlayment (the plans call for a temp roof underlayment, the spec book calls for a ½” underlayment, which I interpret as a1/2” rigid coverboard. Can you confirm which is being called for )

Answer: I am unsure of plan reference for “temp roof underlayment.” See 075400.2.4.C. – First layer is ½” underlayment (Densdeck or equal) over existing sloping lightweight concrete topping.

c. Adhere flat 2” Polyiso rigid insulation

Answer: Second layer. Is this a question?

d. Adhere ¼” gypsum coverboard Answer: Third layer. Question?

e. Adhere 60mil PVC roof membrane

Answer: Fourth layer. Question?

f. Install 22ga cleat + 24ga coping on walls Answer: Detail 1/A4.5 shows indicates the new coping system of 20ga cleats and 24ga prefinished coping. Also see spec 077100. Is there a question on this?

g. Provide 24x36 roof hatch (with safety railing)

Answer: Is this a question? There are two new roof hatches/openings/safety railing/ladders per Keynote 14, Sheet A4.1.

h. Is there any other fall protection required?

Answer: Yes. This includes but may not be limited to Fall protection guardrails per Keynote 1, Sheet A4.1, horizontal lifeline system per Keynote 26, Sheet A4.1, Ladder approach protection per Keynote 27, Sheet A4.1 and A4.10. Also see specifications section 055000 and 118129.

i. Are ISO crickets required?

Answer: Tapered materials may be required to achieve specified slopes. See generals notes A and F, Sheets A4.1 and A4.2.

13. The intent of the lightning protection aspect of the project is to relocate temporarily to facilitate re-roofing/ re-install and re-certify. Will the Fall Protection system, railings, posts, cabling require integrating into the existing lightning protection system?

Answer: Most likely, and that would need to be confirmed by the lightning protection subcontractor and certifying agency for the system.

14. Drawing A4.5, Detail 4 – Can extending the plumbing vent be done above the roof using no hubb ands and pvc sch 40 piping?

Answer: Yes. New PVC piping will need to be painted white to avoid degradation of the pipe.

15. Specification 070150 Part 3 Execution 3.2 Roof Tear Off, A. States that the roof tear off is down to the metal deck. In several other locations in the drawings, the lightweight concrete is to remain. Please advise.

Answer: Lightweight concrete topping is to remain.

16. The condition of the lightweight concrete insulation was not observable during the pre-bid walkthrough. Specification 075400 Polyvinyl Chloride (PVC) Roofing, Part 3 Execution 3.2.

D.1describes unforeseen repairs to existing fastener holes, incidental surface damage, divots, gouges, bird baths, existing rough cold joints. Can the Contracting Officer assign a square footage or an allowance for repairs to existing so that the proposals will be equitable amongst the bidders?

Answer: Not needed but it may be easier to negotiate a contract modification if you provide the assumptions for your offer.

Realistically, the adhered underlayment will suffice for all small anchor holes and divots. Only more extensive areas of damage will need repair and that is impossible to guess at.

17. How many and how often will pull tests be required for this project? Specification 075400Polyvinyl Chloride (PVC) Roofing, Part 3 Execution 3.2. D Answer: Perform pull test at four (4) random dispersed locations agreeable to COR and roofing manufacturer’s representative. Test should be performed using adhesive and ½” underlayment, not insulation, as underlayment will be adhered to lightweight concrete topping.

18. This project will likely experience delays for weather. How many days has the COR set aside for weather delays? Who will make the determination of what constitutes a legitimate weather delay? Closeout Procedures 017700 E.6 asks for the contractor to submit a final liquidated damages settlement statement, (as applicable). Are Liquidated Damages applicable to this project? If so, what amounts?

Answer: No, liquidated damages are not included as part of this RFP.

19. Scope of Work IV Coordination with Owner – B. The contractor is allowed to utilize a limited portion of the existing parking lots for storing and staging. Reviewing the site, it appears that the only parking lot that will not impede on the operation of the hospital is the East parking lot. Can you please define the limited portion of parking lot we will be allowed to use for staging and storage?

Answer: The only parking lot available for contractors will be the southside dirt parking lot, as well as for staging and materials. To be coordinated with ZSU on Pre-Construction meeting

62. We can install as shown with a different attachment method or have another option.

- The connection detail for the anchor points does not make sense. Super Anchor does not have an approved connection detail for their 52-hole baseplate that is compatible with ultralight concrete over pan deck. We would either need to change to a different connection detail with a backer plate, or we would need to change to an energy-absorbing system that allows the anchor to sit on top of the roof composition and use toggle anchors through the pan deck.

Answer: It is acceptable to remove concrete topping at footprint of baseplate and attach directly to deck. Care must be given to not damage metal deck.

Are modular fitting-based guardrails acceptable instead of fully welded guardrails? Something like the below?. These systems are hot-dip galvanized with a 25-year powder coat, Answer: No, there is a concern with attachment of these systems. They are typically surface mounted with heavy steel baseplates with no mechanical connection to the roof. And they typically can’t be modified to accommodate attaching to structure since it requires additional post length.

63. I have reviewed the Asbestos Survey provided for the Zuni Comp. Community Health Center Roofing and Fall Protection - AQ22ZS002. Building 02000 Hospital is assumed to be the Comprehensive Community Health Center based on the provided floor plan. The survey provided does state that ACM is located within the hospital within floor tiles, sink undercoating, exterior window and door caulk, and within the penthouses. There was no samples taken of the existing roof systems contained within this report. Should we assume for the purposes of bidding that the roof to be removed does not contain ACM?a 25-year powder coat, Answer: There are no ACM’s on the roof of the facility as documented in the report.

64. Can the Govt provide results from core samples? Photos/results Answer: No, there is no core test that has been performed.

65. Can the Govt confirm the roof is structurally sloped?

Answer: The structure and metal deck are level. Existing roof slope is provided by the lightweight concrete topping. Tapered materials may be required to achieve specified slopes.

66. If not structurally sloped, will tapered insulation design be provided?

Answer: The structure and metal deck are level. Existing roof slope is provided by the lightweight concrete topping. Tapered materials may be required to achieve specified slopes.

67. Can the Govt provide a detail for the Lightweight Insulating Concrete (LWIC) Answer: The LWIC thickness is not known, the previous design drawings will be sent.

68. LWIC thickness?

Answer: The LWIC thickness is not known, the previous design drawings will be sent.

69. Density & Type of LWIC?

Answer: The LWIC thickness is not known, the previous design drawings will be sent.

70. Moisture content or recent moisture testing results Answer: No moisture content testing results available.

71. Have Fastener pull tests been performed? Please provide any pull test data (this info is required to determine fastener lengths, attachment patterns and deck suitability.)

Answer: No, there has not been a fastener pull test performed.

72. Can their be alternate phasing that can clear out hospital staff from below working areas during different portions of the project? (1-3 day of no access to certain areas of hospital?)

Answer: This could be possible; in such a case the hospital may require no less than a minimum of 2-weeks’ notice to rearrange and reschedule patient visits.

73. There are currently no specifications for the type or quantity of air monitoring within the facility during the completion process. What are the expectations for air quality monitoring?

Answer: To be below the minimum risk levels (MRL) for the chemicals used on the project.

Verify MRL with SDS sheets.

74. We are proposing to collect particulate samples within the facility based off the light weight concrete being used on the roof decking. We will propose our sample quantity and turnaround times from the laboratory pending response.

Answer: To be below the minimum risk levels (MRL) for the chemicals used on the project.

Verify MRL with SDS sheets.

75. We are proposing to use handheld instruments, specifically a photoionization detector, to detect the volatile organic compounds used in the roof membrane adhesion process. The solvents have relatively high exposure limits. Is there a specific percentage of the exposure limit or a maximum amount of volatile organic compounds the Pueblo of Zuni will allow?

Answer: To be below the minimum risk levels (MRL) for the chemicals used on the project.

Verify MRL with SDS sheets. The facility is a federal location and the Indian Health Service is the AHJ.

76. We are planning to perform phased removal of the roof and phased replacement of the membrane to ensure the tightness of the building envelope during construction. Is it possible that the Pueblo of Zuni could phase the patient and staff concentrations beneath our proposed work areas to minimize negative impact during the potential chemical errant emissions?

Answer: This could be possible; in such a case the hospital may require no less than a minimum of 2-weeks’ notice to rearrange and reschedule patient visits. The facility is a federal location and the Indian Health Service is the AHJ.

77. What provisions are being made for air handling equipment with vents or air intakes near the work area operations? If we seal these off from the construction activities or asbestos abatement, what secondary systems is the Pueblo of Zuni incorporating?

Page 78:

1.6 PROJECT CONDITIONS

A. Buildings will be occupied during the work. Conduct reroofing so Owner's operations are disrupted as little as possible. Provide COR with not less than 72 hours' notice of activities that may affect service unit’s operations.

1. Coordinate work activities daily with COR so COR can place protective dust or water leakage covers over sensitive equipment or furnishings, shut down/restart HVAC and fire alarm or -detection equipment if needed, and evacuate occupants from below the work area in an emergency.

2. If structurally impaired areas of deck are discovered, notify COR to evacuate occupants from below the affected area. Verify that occupants below the work area have been evacuated before proceeding with work over the impaired deck area.

3.1 PREPARATION

A. Coordinate with Owner to shut down air-intake equipment in the vicinity of the Work. Cover airintake louvers before proceeding with reroofing work that could affect indoor air quality or activate smoke detectors in the ductwork. It appears that the COR will be responsible for providing protection for dust that may occur during the demolition and installation below the roof, and the contractor is responsible for coordinating this scope (HVAC shutdowns and covering air intake louvers). We are assuming that the scope of work for the new davit crane will be above a space that can be easily contained, a Type B Low Risk, Class III.

- The question is, is the space below the roof including the interstitial space between the hard lid ceiling and roof deck, as well as the areas below the hard lid ceiling considered Class III, requiring negative pressure and floor to ceiling containment?

Answer: Yes and No, the interstitial space between the lid/ceiling and the roof deck is considered both dependent on the area of the hospital. The inpatient area behind the 2-hr firewall are ducted. The business occupancy areas are plenum.

- Is the interstitial space between the roof deck and ceiling an HVAC plenum?

Answer: Yes and No, the interstitial space between the lid/ceiling and the roof deck is considered both dependent on the area of the hospital. The inpatient area behind the 2-hr firewall are ducted. The business occupancy areas are plenum.

- Drawing S2.1, detail 1 describes the Jib Crane as “jib crane per mfr.2000 lbs capacity max” Specification 114012 Davit Cranes 2.1 A. states that the davit crane is to have a capacity of 3000 lbs. Please advise which is correct?

Answer: The specified 3,000lb capacity crane is to be provided. The STRUCTURE is limited to a 2,000lb lift and signage is required to be installed at ground level and on lift according to Details 3 and 4 on Sheet A4.10. Due to reach requirements, the crane will never be utilized in its max capacity configuration.

92. The fall protection product used as the design basis ( Super Anchor) for a CRA-W would require 4- 3.75 anchors on a 16 x 16 base plate.

The drawings and specifications do not provide a thickness of the existing lightweight concrete deck. Can the COR provide as-built information that demonstrated the minimum compressive strength of the concrete and the thickness of the roof deck.

Answer: The LWIC thickness is not known, the previous design drawings will be sent.

93. Can the deadline for this project be extended 4 weeks?

Answer: Proposal date has been extended to December 16, 2025.

94. Drawing A4.1 Key Note 13 states “Abandoned Equipment/Roof Penetration. Remove completely. Infill Deck. Roof Over with new system” There is a lot of equipment in this area.

Please provide a description of the Abandoned Equipment to be removed.

Answer: Contractor will verify equipment to be abandoned with Maintenance staff; there is no list available.

95. Would the Government consider extending the proposal due date by several days to allow sufficient time for pricing updates and coordination based on the latest information?

Similar Question: With the RFI answers being critical for pricing, and the holidays, can the Bid Due Date be extended allowing for contractors and suppliers to evaluate and change pricing if needed? A one week extension after RFI answers is preferable.

Answer: Proposal date has been extended to December 16, 2025.

96. Does penthouse 1 get guardrail? It only shows the guardrail icon on penthouse 2.

Answer: Disregard Keynote 1 at Penthouse 2. Penthouses get new safety rails at new roof hatches per Keynote 14.

97. What’s the thickness of the deck? Insulation depth and concrete depth?

Answer: The LWIC thickness is not known, the previous design drawings will be sent.

98. Can Drawing be provided for the entire floor below the roof? Since penetrations are required that will enter the space below, the KTR’s need to understand the rooms below for ICRA pricing.

We would need to know the ceiling constructions, sizes of rooms and the room functions such as if there is an Operating Room which requires a higher level of ICRA.

Answer: The original roofing and structural plans will be sent.

99. Please confirm the TERO appointed employees will be required to attend Fall Protection training.

Answer: Refer to H.50 and 52.229-3. IHS does not manage the Tribe’s TERO. Offerors are responsible for allowing for all applicable state, local taxes and fees within their bids and to perform their own due diligence in ascertaining them.

100. What is the TERO ratio of employees to Roofers?

Answer: Refer to H.50 and 52.229-3. IHS does not manage the Tribe’s TERO. Offerors are responsible for allowing for all applicable state, local taxes and fees within their bids and to perform their own due diligence in ascertaining them.

Answer: The previous design drawings will be sent.

102. Since no core test allowed during the site visit, we need the information on the existing thickness of the roof system to determinate if the existing roof slope is on the insulation or on the roof deck.

Answer: The previous design drawings will be sent.

103. Plans show to provide ¼” per foot slope, is the intent to add new taper system to the entire roof.

Answer: The structure and metal deck are level. Existing roof slope is provided by the lightweight concrete topping. Tapered materials may be required to achieve specified slopes.

104. If we are adding taper system, is the responsibility of the contractor to make height adjustments to wall base flashings and curbs.

Answer: Yes, if required.

105. Asbestos report for Building 2000 only show testing on the penthouses and show no testing on the roof assembly. Are we to assume no asbestos on the existing roof assembly.

108. Under 070150 3.2 Roof Tear off says to remove the roof down to the metal deck. Is the intention to remove the roof membranes and the lightweight concrete also?

Answer: Existing roofing to be removed. Existing lightweight concrete topping to remain.

109. Per the manufacturer’s guidance, a 1/2" cover board is not approved for installation over the existing lightweight concrete. Any moisture retained within the concrete could compromise the integrity of the coverboard. During the site visit, several areas were observed to have soft spots, indicating potential moisture presence. The manufacturer recommends installing a vapor barrier over the lightweight concrete to mitigate moisture-related risks.

- Answer: We do not know what manufacturer is being quoted, and are not aware of the observed conditions, we take no exception to adding a vapor barrier between the existing lightweight concrete topping and the new ½” cover board. Addition of this layer would factor into discussions/decisions related to adhered and mechanically fastened approach to the roofing system.

110. Is it possible to get the original drawings from the lightning protection design and a copy of the UL Master Label or LPI Certificate?

- Answer: There are no drawings of the lightning protection system. Unfortunately, the previous design and roofing project did not have this information either.
