REQUESTS FOR INFORMATION #1

FCI ASHLAND, KY

REPAIR/REPLACE ROOF PROJECT

IFBP01021200001

1. Will you allow 10 hour days to help with the completion of the job? Either 4 or 5 ‐10 hour days.

RESPONSE: The work week will be forty hours, eight hours per day, Monday through Friday, excluding Federal holidays.

2. Will the roofing contractor be allowed to work weekends?

RESPONSE: No.

3. In your SOW work it states to spray over the EPDM roof system on the flat roofs. A warranty will not be given for three roof systems. As my past work experience with the Ashland prison, there were two roof systems (EPDM and built up) on the flat roofs. If we are to remove the EPDM roof system, will we be allowed to wet‐vac the built‐up roof and apply the foam system onto the built‐up roof?

RESPONSE: The Specifications require the installation Contractor to prepare each individual roof surface to a Manufacturer approved substrate. The Contractor is responsible to comply with their respective Manufacturer’s roof system(s) guidelines to ensure an acceptable surface is in place for a 10 year system warranty. If a wet‐vac process is needed or is necessary to ensure an acceptable surface on the built‐up areas, then the wet‐vac should be estimated in the final cost of the project. The areas with ballast EPDM‐type roof systems with concrete roof decks are: E‐Unit (EPDM over built‐ up), G‐Unit (EPDM), H‐Unit (EPDM), and partial areas on the Food Service Building (EPDM over built up). The remaining portion of the Food Service Building (EPDM) is a wooden deck of approximately 9200 square feet.

4. Will all roofing personal have to stay in one area of work? (Other words have two crews going).

RESPONSE: The Contractor will bid the project as if his/her’s vehicle will be confined to the area of the compound (North‐side / South‐side) in the Contractor‐supplied, proposed schedule (i.e. working in close proximity) for each day. No working on separate buildings on opposite sides of the compound. Two escorts will be provided (an escort on the roof and an escort on the ground).

5. What weight restrictions, if any, are applicable to equipment?

RESPONSE: No weight restrictions for general use vehicles on the ground.

6. What equipment, including port‐a‐potties and dumpsters, has to be removed to the staging area at the end of each workday?

2 | P a g e

RESPONSE: All equipment will be confined to secure staging areas designated by the owner. No dumpsters, porta‐potties, and equipment/trailers will be left unattended during off‐hours. These areas will be confined inside the compound to eliminate daily removal. Items (i.e. cutting tools, long lengths of rope and hoses, ladders over 6’, etc.)

must be removed from the secure compound daily. A staging area at the rear of the facility will be provided for these items.

7. In the event of emergency or other situation where FBOP might require contractor to leave premises during their process a roof could be left unprotected. In this event, will FBOP accept responsibility for any damage or additional cost incurred as a result?

RESPONSE: In the event of a situation beyond the control of the Contractor, the owner (FCI) will assume responsibility for damages. Any situation that is not the result of an emergency is the sole responsibility of the Contractor.

8. Can you provide additional detail on the individual roofs in Part I as follows:

‐ History of roof – age, last roof system application and year installed?

‐ Existing deck – Concrete? Wood? Etc.

‐ Composition of existing roof over the deck. Built‐up? Polyisonate and EPFM?

‐ For polyisonate board can you provide depths at center and edges of roofs?

Slope?

‐ Desired slope of roof?

RESPONSE: A‐Bldg (shingles (mid 1990s)), B‐Bldg (shingles (mid 1990s)), E‐Unit (ballast EPDM with concrete deck (late 1980s)), Food Service Warehouse (ballast EPDM with wooden (9200 SF) and concrete deck areas (8100 SF) (late 1980s)), J and K‐Units (shingles (mid 1990s)), Laundry (shingles (mid 1990s)), and N‐Bldg (shingles (mid 1990s)), were built in 1939‐41. G‐Unit (flat roof portion ‐ ballast EPDM with concrete deck (late 1980s) and shingles (mid 1990s)), built in the 1970’s. H‐Unit (ballast EPDM with concrete deck) built in the mid 1980’s. Approximately 2 ½” to 1 ½” taper on the polyisonate board. Slope should provide adequate drainage for warranty purposes.

9. Pursuant to last item two‐inch depth as specified will not provide slope to drain to meet manufacturer specifications for warranties. Will this be considered under a change order after manufacturer/contractor has had a chance to more closely inspect the roofs?

RESPONSE: Part I, 3.3 INSTALLATION, C. should state a minimum thickness of 2”±¼”.

Proper thicknesses will be followed to ensure adequate drainage/slope is present as per Manufacturer’s requirements for slope/drainage.

10. There are a number of items in the preparation prior to work that may not be known until removal of the existing gravel and EPDM. These include wet and saturated areas, roof deck damage, etc. Will uncovered items be handled with a change order to meet manufacturer’s warranty requirements?

RESPONSE: Any changes will be handled by change orders.

11. The general summary on page 4 of 17 talks about a direct bond application of foam “over” EPDM as does some of the Part II preparation 3.2 on page 9 of 17 where it discusses detergent cleaning. Is it correct that all EPDM roofs are being removed and cleaning will be of remaining built‐up or concrete decks?

RESPONSE: The term “over” (Part I, 1.1) refers to the structure, not the roof membrane.

Any non‐adhered EPDM‐type systems, built‐up, etc. will be removed to comply with an approved substrate. It is correct that all EPDM roofs are being removed and cleaning will be of remaining built‐up or concrete decks.

12. At completion will FBOP take care of any incidental damage to grass, landscaping, and sidewalks or should contractor budget for potential needs and costs?

RESPONSE: FCI Ashland will assume responsibility of any needed restorative work to the grounds caused by general foot and vehicle traffic by the Contractor. The FCI does request that they are notified of any extreme weight issues so provisions can be made accordingly.

13. There are some variances in square footage related to parapet walls, etc... While not large in total, will FBOP be willing to review actual square footage measurements with a contractor and allow adjustments, either increases or decreases? If so would such changes be handled via a change order?

RESPONSE: The Contractor will bid the project as per the figures provided in the drawings and specifications. Any changes will be handles accordingly once the project is awarded and work commences.

14. The silicone specified calls for high‐solid GACO 2000 silicone. (‐ or equivalent is assumed.)

The usual return on this for the extra cost is the ability to apply it in one coat versus two.

However, your spec calls for two applications of base coat and top coat at 11 mils each to have a contrasting color, offsetting the labor savings. A regular silicone could be used at less cost (adjusting the gallon per square foot application rate) to achieve this. You also call for the silicone granular or finishing coat over the latex roof portions. Is the silicone specification and indicated usage what is desired?

RESPONSE: Yes, as per specifications.

15. Is the expected warranty a ten‐year manufacturer warranty?

RESPONSE: Yes.

16. On Pg. 4 0f 17 Part 1, 1.1 it states to apply over pre‐existing weathered EPDM. Since the

EPDM is ballasted and not fully adhered, the existing system will have to be completely removed for the new roofing system to be applied. Is this the consensus of the engineers?

RESPONSE: The term “over” (Part I, 1.1) refers to the structure, not the roof membrane.

Any non‐adhered EPDM‐type systems, built‐up, etc. will be removed to comply with an approved substrate. It is correct that all EPDM roofs are being removed and cleaning will be of remaining built‐up or concrete decks.

17. Does the entire facility have a concrete substrate or are their parts that have metal and wood? If, so which are which.

RESPONSE: The areas with ballast EPDM‐type roof systems with concrete roof decks are: E‐Unit (EPDM over built‐up), G‐Unit (EPDM), H‐Unit (EPDM), and partial areas on the Food Service Building (EPDM over built up). The remaining portion of the Food Service Building (EPDM) is a wooden deck of approximately 9200 square feet. The shingled roofs are either wooden or concrete decks with roll felt and asphalt shingles.

18. Will the contractor be given a laydown area for material, dumpsters, tools and equipment inside the gated facility?

RESPONSE: All materials, dumpsters, tool and equipment will be confined to secure staging areas designated by the owner. No dumpsters, porta‐potties, and equipment/trailers will be left unattended during off‐hours. Some of these items can be confined inside the compound to eliminate daily removal. Items (i.e. cutting tools, long lengths of rope and hoses, ladders over 6’, etc.) must be removed from the secure compound daily. A staging area at the rear of the facility will be provided for these items.

19. The contractor will need access around each of the buildings for equipment to place and pull from the roof. Are there areas that restrict the contractor from using heavy equipment such as an off‐road fork lift?

RESPONSE: No weight restrictions for general use vehicles on the ground. FCI Ashland will assume responsibility of any needed restorative work to the grounds caused by general foot and vehicle traffic by the Contractor. The FCI does request that they are notified of any extreme weight issues so provisions can be made accordingly.

20. Will the core sample pictures be made available to the contractor for bid purposes?

RESPONSE: No. The description of each roof area is included in the RFI and Drawings/Specifications documentation.

21. Are there specific buildings that your engineer requires more than what the manufacture recommendations are for the preparation before applying the foam roofing system. i.e wet‐vac. If this is the case which buildings would the engineer want this task performed?

RESPONSE: The Specifications require the installation Contractor to prepare each individual roof surface to a Manufacturer approved substrate. The Contractor is responsible to comply with their respective Manufacturer’s roof system(s) guidelines to insure an acceptable surface is in place for a 10 year system warranty. If a wet‐vac process is needed or is necessary to ensure an acceptable surface on the built‐up areas, then the wet‐vac should be estimated in the final cost of the project. The areas with ballast EPDM‐type roof systems with concrete roof decks are: E‐Unit (EPDM over built‐ up), G‐Unit (EPDM), H‐Unit (EPDM), and partial areas on the Food Service Building (EPDM over built up). The remaining portion of the Food Service Building (EPDM) is a wooden deck of approximately 9200 square feet.

22. The bid documents did not specify any requirements and details regarding plans required for this contract. What plans will be required such as QCP (Quality Control Plan), and APP (Accident Prevention Plan)? If required, the preparation of these plans will require development of each specific work plan for submission to the Government for review and approval. What plans are required for this bid package?

RESPONSE: As stated in the pre‐bid conference meeting, the Contractor will provide FCI Ashland with an estimated sequence of events so proper escorting and security provisions can be made to accommodate the work. FCI Ashland requires that the Contractor comply with Manufacturer’s requirements to ensure a 10 year materials / system and 2 year workmanship (labor) warranty. The APP will be provided to the FCI Safety Manager (OSHA standards) once the project is awarded.

23. The Statement of Work under Section 1.6, Warranty, requires that the material supplied will meet or exceed physical properties as published. The contractor guarantees that work will be free of defects in coating application. However, there is no stated time period for the warranty requirements under this section. What is the time period for this warranty by the manufacturer such as Five, Ten, Fifteen or Twenty years?

RESPONSE: The FCI requires a 10 year materials / system and 2 year workmanship

(labor) warranty.

24. Are there any specific weight limitations for mobilizing all necessary equipment to install the new roof systems inside the prison at any specific locations in Part I and Part II?

RESPONSE: No weight restrictions for general use vehicles on the ground. FCI Ashland will assume responsibility of any needed restorative work to the grounds caused by general foot and vehicle traffic by the Contractor. The FCI does request that they are notified of any extreme weight issues so provisions can be made accordingly.
