Building 16 Flat Roof Replacement RFI Questions and Answers

1. There is no mention of coverboard or insulation for the project. Is that correct?

Answer: Yes just the flat roof

2. The spec calls out IKO rolled roofing. Are we able to install another rolled roofing project that meets or exceeds the specs of IKO?

Answer: Yes EDPM

3. Will there be any formal spec book released for the project?

Answer: NO

4. Solicitation calls out this in the general requirements-

5. "Contractor will replace flat roof with EDPM OR IKO roofing, with a 30 year Warranty. All material will be approved by the carpenter shop Forman."

6. This seems counter to what is called out in the SOW which is that the new flat roof will be rolled roofing. Is the case that the new roof is a 30-year NDL EPDM roof and that the rolled roofing items were placed in the scope accidentally?

Answer: Either or EDPM or IKO

7. To clarify is the area highlighted in blue below is the area included in the scope and not any of the steep sloped shingles.

Answer:- NO, it’s Just the Flat room

8. Insulation Not Included in Current Scope:

The current scope does not include the addition or replacement of any roof insulation. Could you please confirm whether insulation is intended to be part of this project, or if the work should proceed without it?

Answer: Insulation is not included

9. Conflicting Roofing System References:

The scope references IKO torch-down granulated roofing in one section, while another section specifies replacing the flat roof with EPDM roofing and a 30-year warranty. These are two completely different systems. For clarity and accurate pricing, please confirm which roofing system is required:

Answer: It can be either I need to put both as choice

· IKO torch-down modified bitumen

· EPDM single-ply membrane Material Recommendation:

After further discussions with subject matter experts, we would recommend installing either EPDM or TPO, as both systems offer superior performance, durability, and long-term reliability compared to torch-down products. Additionally, IKO is generally considered a lower-tier roofing manufacturer relative to others in the commercial roofing industry. EPDM or TPO would provide a higher-quality, longer-lasting solution for this facility.

10. Additional Roof Photos:

We would greatly appreciate it if you could provide any additional photos of the roof to assist with our assessment.

11. As per the statement of work Outlined on page 4 of the solicitation, it references, new IKO granulated roll roofing, But then in section C. General requirements it references EPDM with a 30 year warranty. Please clarify What product is to be used?

Answer: It can be either The Carpenter shop Supervisor will approve all material

12. As per the statement of work, it references replacing any sheathing, as necessary. Are we to provide a unit price per square foot for any sheathing replacement?

Answer: IF a piece of sheathing is compromised we need to replace, if the roof is good nothing need to be done .

13. As per the statement of work, the estimated replacement quantity is 2000 SF but the actual roof area is closer to 3000 SF are we replacing the whole roof area or just the 2000 SF section? \ Answer: This was a rough estmiate, the actual square footage is 2950 SF image1.png
