RFP 25-WA-01

Water Treatment Facility Re-Roof

Addendum #1

1. Question: Hello, My name is Zoey and I am with New Standard Construction. We want to place a bid on this project but the Online quote/Bid button is not working.

Can some one assist me on this? Thank you

Answer: The bid packet needs to be completed and shipped or delivered in person per bid instructions.

2. Question: Is it possible for a General Contractor company to take part in the bidding process by subcontracting a roofing company?

Answer: Yes, but the roofing company will need to be identified and their prior experience and capacity listed. The roofing company will need to be licensed to work in the State of Florida

3. Question: Regarding the section of the bid reference that requires multiple jobs related to the SOW of the RFP, is it acceptable to include jobs located outside of Florida?

Answer: You may, but please note that roofing work needs to be done according to Florida Building Code, and the "experience" category of evaluation may be affected.

4. Question: We were in attendance yesterday at the pre-bid and we have only one concern. The screened enclosure over the water basin, sits on top of a low profile continuous concrete curb. We are assuming you intend for us to flash up to and under the aluminum cap flashing. If so, there is not much room, and we need to know exactly how much vertical height is available to accommodate the new tapered insulation and membrane. We were not able to test this location above the adjacent roof deck. The entire perimeter base flashing of screen enclosure must be a waterproof application after the existing roof system is removed and new system installed. Are there any structural or as-built drawings available?

Answer: An original roof plan from 1969 has been uploaded to Vendor Link.

Functional drainage is a requirement of this project, so additional site visits are available to those who need additional information.

5. Question: I am inquiring if you could please provide the roofing scope of work for this project? From all the documents I have seen there is no specification on roofing material simply a complete tear off and replacement with a new modified bitumen roof.

Answer: An APP Modified Bitumen Roof is acceptable

6. Question: What is the scope at the abandoned curbs?

Answer: Please leave the abandoned curbs in place

7. Question: What minimum thickness or R value is required for the tapered insulation at the drains?

Answer: Per Florida Building Code requirements

8. Question: The existing roof flashing height at the screened in basin and doors are low at about 4” flashing height. Please advise if contractor should figure going back with same thickness as existing roof to keep existing heights the same?

Answer: Please see Florida Building Code Section 15.03

9. Question: The existing lightweight is sloped 1/8” per ft. Please confirm 1/8” per ft tapered insulation is acceptable to match existing slope. Note: 1”/12 slope listed on scope of work is incompatible with the flashing heights at the screened area. If the higher slope is required, please advise if the screen wall will be modified by others and provide guidance on flashing details. Tapered iso is also not available in 1”/12 slope.

Answer: Florida Building Code requires a minimum slope of ¼” per foot.

10. Question: The RFP lists liquidated damages to begin 90 days after notice to proceed.

Can this be modified to be 90 days after the permit application is approved since that time period is outside of the contractor’s control?
