FCI Estill, Replace Roofs Questions and Answers

# Contractor Question FBOP Response

1 Daily tool inventories are required. Some items are considered “consumables”, not tools, and are broken/thrown away in the normal process. As an example, razor knife blades get dull and are changed frequently and snap blades have multiple segments. Due to the security issues prevalent on the site, what additional precautions/regulations will be enforced for these types of items.

All blades have an accountability requirement. Blades will be inventoried in and inventoried out, so dull blades must be retained and removed from the institution. For snap blades, the heel of the blade with the stabilization holes will be retained for accountability.

2 What is the protocol for a tool/consumable which is unaccounted for during the daily tool inventory? What restrictions will be placed upon the crew members until such time as the disposition of the tool can be determined?

Consumables (e.g., glue, caulk, screws, washers, etc.) are not typically counted, since they are not a tool. However, long screws are concern as a weapon, so any screws dropped from the roof should be immediately reported to the BOP escort.

Lost tools must be located before exiting the institution. All contractor staff shall assist in the search.

3 Temporary power will be needed in all areas of the project, including the tool storage area. Unfortunately, this item was overlooked by all of us during the walk thru. The drawings do not indicate locations where power panels are located or if courtesy power outlets are available. Can this information be provided in order to determine the extent of the electricians scope to provide said power? Are there specific institution requirements for the temporary power sources to be removed at the end of each shift?

Many of the exhaust fans have an electrical outlet under the cover. In areas that do not have readily available outlets, the contractor will be permitted to run temporary power from the nearest available power source. Temporary connections must be returned to original conditions by the contractor when that section of the roof is completed.

4 30 yard dumpsters were discussed as a means of debris removal; however, due to the physical logistics of getting the large amounts of debris from the roofs to the dumpster, the use of a RTHL forklift and a trash hopper to move the debris would be more effective. In several areas the dumpster could not even be placed near the roof edge. In addition, the forklift would be used to transport the new materials from the “lay down area” to the work site.

The contractor has the option of using its own trash hoppers.

There are logistical issues that should be noted. Morning: The full container will be removed from the rear sallyport and placed near the contractor’s laydown yard. An empty container will accompany the contractors as they walk to the job site.

Afternoon: the full container will be moved to the rear sallyport. If partially full, the container will be moved to the loading dock apron. Due to high BOP staffing requirements to escort lift equipment and containers, these are the only two times of the day containers will be moved.

5 It is stated in the “Statement of Work” Section F. Paragraph 10 that “lulls/boom trucks will only be allowed during certain times when the institution is locked down” and that “loading of roofing materials should be completed in the mornings, prior to the inmate compound being opened”.

Can the normal operating schedule for these “compound openings and lock down periods” be disclosed for preplanning purposes?

Movement of materials/trash will occur simultaneously with contractors entering and exiting the institution at the beginning and end of the workday.

6 We also discussed the use of an OSHA approved “man lift platform” (using the RTHL forklift as an elevator) for use specifically on the Housing Units. This would eliminate the need to access the roof through the living environment and reduce contact with the inmates in this area. The access would be from the rear of the buildings and in a “non‐inmate access area”. This would however, require an operator (and therefore one Escort) to remain on the ground constantly throughout the day. Can the logistics of this be considered for approval “pre‐bid”? With the two man Escort team provided, will this present a logistical issue for the facility? If approved and needed, would there be an extra cost to the contractor to pay for an additional escort and what would be the cost to have an additional escort provided for the “ground personnel”?

One escort on the roof and one escort on the ground is approved by the FBOP. There is no means for the contractor to pay for salaries for additional BOP staff. The contractor should plan on being limited to two full‐time FBOP escorts, which will be supplemented when needed for vehicular movement on a very limited basis.

7 Is there a limit to the number of personnel which can be submitted for security clearances? I believe that, in addition to the expected personnel on site, we would like to submit the names for contingency personnel. This will be to allow for crewman/supervisor substitutions in order to maintain full crew compliments in the event of sick days, vacations, etc. Likewise, we expect there to be regularly scheduled progress meeting which will require site visits by administrative personnel whom must also receive the appropriate clearances. It was stated today that there does not need to be “an issue” in a persons’ background to be refused clearance, nor will we be told why a clearance is denied. With that in mine, we really have no way to pre‐screen personnel to insure positive results.

There is no set limit to the number of personnel submitted for security clearances. However, the contractor should submit personnel that are reasonably expected to access the site as a primary or backup employee, due to the high cost to the BOP for background investigations.

8 It is almost guaranteed that windborne debris (mostly small Styrofoam pieces) will be swept off the roof by the wind, no matter how much effort is made to contain it. Cleanups will need to be made periodically to collect this debris in the inmate yard areas. How often will this be allowed/required?

A reasonable effort should be made by the contractor to minimize windborne debris. The contractor will be responsible for cleanup in inmate restricted areas (i.e., “No man’s land”).

However, debris in inmate populated areas (i.e., the inner compound and the recreation yard) will be cleaned up by inmates. The frequency of the contractor cleanup will be coordinated with the escorting FBOP staff and may vary from daily to weekly, depending on the type and quantity of debris.

9 On the Recreation building (plan A4) there is a vertical metal wall which overlaps the existing membrane roof. Removal of the wall panels and louvers will substantially alter the scope of work to install the new roof membrane appropriately. There is a possibility of adding an additional piece of trim to the underside of the metal panels to provide an overlap for the new membrane to be sealed properly (less that 4” but possibly adequate). Please advise on the engineers preferred approach to this issue? Detail D2/A218 is not clear for a replacement membrane roof closure.

The FBOP is receptive to additional trim to avoid removing the wall panels. However, the detail must be approved by the membrane manufacturer to ensure a warrantied installation.

10 A similar situation occurs on the concrete patio roof at the rear of the same building (A5) and again on the Camp Core Building (A12 ‐ concrete dock roof/rear patio roof). At these locations the metal roofing panels overlap the existing membrane roofing. Please advise as Details F1 and H1 on A240 do not address roof membrane replacement?

There are areas of concern where the current low slope roofing meets the Standing Seamed metal roofs. It appears that there are areas where entire wall panel systems and standing seam roof panels will need to be completely removed to achieve proper flashing heights per warranty requirements? Is this an item that was taken into consideration when preparing this solicitation?

The contractor should plan on providing the most cost effective means of replacing the membrane using approved details (whether standard details or specially approved custom details) from the membrane manufacturer to ensure a warrantied installation. Removal of roofing panels may be required if an alternative detail does not receive manufacturer approval.

11 The central roof area on the Camp Core Building has multiple issues with unused equipment and debris where equipment has been demolished and abandoned. It was indicated that other venting/equipment was to be eliminated as well. Can additional drawings be issued to accurately reflect the equipment to be removed and identify roof decking repairs needed in this area?

No additional drawings are available. However, one large exhaust fan will remain and the contractor shall deck over all other penetrations.

12 While on the Food Service Building Section, A8 and A9, several areas were discussed wherein equipment vents were to be removed and capped off “under deck” by the institution maintenance personnel. There would be a requirement for roof deck repairs in multiple areas in this zone. Please provide the information conveyed verbally on the roof, in writing and if possible a drawing with locations and approximate size of repairs?

There were curbs and pipes where abandoned equipment was located in several locations. It was discussed on site that the Prison would be responsible for cutting and capping lines below deck and the contractor would be responsible for closing the hole in the roof decking from topside.

Please confirm.

Hot water supply and return lines from removed equipment will be capped below the decking, eliminating two sleeves in six

(6) locations. The corresponding support curbs can then be demolished by the contractor. The corresponding capped duct opening should be “re‐decked” over. The contractor should utilize decking of the same type as the original decking (i.e., fluting configuration and gauge). The decking splice should lay over the existing decking and extend to/past the nearest bar joist. The new decking should be spot welded in place.

Alternately, only the opening could be infilled if appropriate angle iron supports are installed. In the future, additional information will be included as part Amendment 0002.

13 We request structural drawings for the roof areas designated for replacement. If these are available, we would like to have the drawings which show the roof slope only.

The structural drawings showing decking slope will be posted as part of Amendment 0002 when available.

14 In section 2.1.A.3 of the PVC roofing specifications, it states that the contractor must "meet local building code requirements". If that is the case, SC abides by the 2009 IECC requiring minimum R‐20 (3.5" iso) on roof construction projects including replacement. However, in 2.1.C., a single layer of 3" iso (R‐17.4) is specified. Please clarify.

Yes. The roofing system as a whole should provide a minimum of R‐20. If cover boards or other means will not provide that, the base thickness of the rigid isocyanurate foam insulation board may need to be increased over the minimum 3” thickness.

15 The overflow scuppers are presently at the finished roof surface height. It was discovered during the walk through that the existing roof insulation is 2.5" iso. Regardless of the response from BOP about the thickness of insulation, there will be an issue with the height of the overflow scuppers during construction (either 1/2" or 1" will be lost to new insulation) which could affect overall drainage. Will the overflow scuppers be raised?

During the site visit it was discussed that the current detail on the through wall scuppers was not what needed to be put back. It was mentioned to do away with the screen on the interior side and the louvered look on the exterior side and have a completely open detail per SMACNA Details. Please confirm.

The present scupper height above the roof height varies considerably, since they presently are placed to match the coursing of the CMU veneer. The present configuration of a fine screen on the inside face and a narrow aluminum louvers on the outside face is unreliable in the event of a storm with windborne debris. The contractor should remove both the screen and louvers and provide a standard open scupper with hemmed sheet metal edges or a prefabricated metal scupper insert. The appearance on the exterior of the building should be reasonably attractive. Nominal raising of the roofline, partially blocking the scuppers will be tolerated, as long as the membrane manufacturer approves this condition. Any scuppers with less than 35 square inches of open space, should be enlarged. Tapering of the insulation near the scupper will also be considered, as long as it does not negatively impact primary flow to the roof drains.

16 Since rusted metal decking was discovered during the walk through near the damaged hot exhaust vent, it is reasonable to expect that other areas of the metal deck have rust damage. Will line items be added to the contract documents for roof deck replacement and/or clean and prime existing metal deck if possible?

It is assumed that all metal decking is acceptable, other than the metal decking you have noted. The repair of that rusted metal decking above Laundry that you have noted will be added to the scope of work as part of Amendment 0002 and should be included in the contractor’s bid price. If any additional metal decking is found to be damaged and in need of repair, it will be handled as a differing site condition after award.

17 What is the retainage on this contract? The Bureau of Prisons will not withhold retainage unless a contractor’s performance is endangering the successful completion of the project within the prescribed period of performance.

18 Please provide a photograph of the lay down area and approximate distance from contractor’s entry point?

No photos will be provided due to security concerns. However, any part of the large open field behind the Rear Gate can be utilized (either to the left or right of the rear gate). The approximate distance to the point of entry (Rear Gate) is 100 yards.

19 Will alternate roofing systems be considered? No. The contractor should bid a roofing system that meets the salient characteristics detailed in the existing statement‐of‐ work, specifications, and drawings.

20 Where a ladder is used for roof top access what will the security requirement be for the ground level while work is undergoing? Will the Prison Personnel provide a safe watch for this or will the contractor need a man on ground at this point of entry onto roof top for duration of work?

The contractor will not be required to provide an employee at the bottom of the ladder continuously. The BOP will provide appropriate security.

21 Will prison personnel photo/video document pre‐existing conditions as far as grounds current condition, interior current conditions like stained ceiling tiles etc. for reference during the project start up?

Prior to work in each area, a representative of the contractor and BOP shall visit each area and document existing conditions, noting pre‐existing damage. The BOP will take digital photographs and provide electronic copies to the contractor.

22 Is there a limit on parking for the contractor? Number of vehicles, etc.? The BOP will provide adequate parking for contractor vehicles.

23 Are there any restrictions on delivery times or dates? The contractor must accept his own deliveries. The BOP will not sign for deliveries. Deliveries should be scheduled between 6:30 AM to 7:30 AM and/or 3:00 PM to 4:00 PM, if possible.

24 May have missed it, but are there any provisions in the specs for bad weather days?

No. The typical weather patterns for Estill, South Carolina were considered when developing the period of performance for the project. No additional days or time extensions will be granted unless the contractor can demonstrate that the particular weather that was encountered was unusually severe for Estill, South Carolina during the particular time frame in question.

Also, if unusually severe weather is encountered, it will be incumbent upon the contractor to demonstrate that the unusually severe weather actually impacted the schedule. The contractor should not assume that rain days will be arbitrarily granted, as rain does not represent an unusual weather event in and of itself.

25 If there are any times during the contract where the Prison has to stop work due to an incident outside of anything to do with the work, will this time be given back to the contractor as a rain day or delay?

If an excusable delay happens to occur (such as an institutional lockdown for an extended period of time), the Contract Administration Office will review each on a case by case basis and determine whether a time extension is warranted. With regard to weather related issues, the threshold for the contractor to receive additional days is rather high (see answer #24 above).
