5. Section 01 11 00 requires all roofing work to be performed by the successful bidder’s own crews. Please confirm whether a qualified, manufacturer-approved standing-seam roofing subcontractor may be used for Deck 2. Response: A manufacturer approved subcontractor may be used to install the standing seam sheet metal roof system.

6. Section 01 11 00 requires the 2-inch and 3-inch polyiso layers to be mechanically fastened together and the high-density cover board adhered. Section 07 53 23, Paragraph 3.5.B, states that the insulation boards shall be fully adhered. Please confirm the required attachment method for each insulation and sheathing layer.

11. Note J on R1.0 requires seven new double-wall galvanized flue pipes with caps at Deck 2.

Please provide the required diameters, lengths, material specifications, connection requirements, and identify whether replacement or modification below the roof level is included. Reponse: The Contractor is to field verify the dimensions and conditions. It is assumed that some work may be required below the roof deck. Flue extensions shall be fastened to meet the 2024 IMC requirements.

12. Please clarify the snow-retention scope. R1.0 identifies two rows of “snow retention walkpads” and also requires snow-retention bars with ice stops. Please identify the required product, roof areas, number of rows, and limits of installation for each system. Response:

The plans call out and indicate where each item is to be used.

13. Please provide the hazardous-material survey and laboratory report referenced in the

Advertisement. Please confirm that any asbestos or other hazardous materials discovered outside the negatively tested EPDM membrane will be tested, removed, and paid for by the Owner in accordance with Article 35.3. Response: The findings will be distributed to the selected contractor at the pre-con meeting. The government understands if there is an unforeseen asbestos during removal, the proper steps will be taken.

14. Please confirm how deteriorated or storm-damaged metal decking and structural components discovered after tear-off will be handled. Should bidders include an allowance or unit price for deck replacement beyond the specifically identified curb-opening patches?

Response: No deck damage is anticipated. If any is found it will be handled by a field order.

15. The anticipated construction period is October 1 through December 30, while Section 07 53 23 prohibits EPDM installation when the forecasted daily high is below 50 degrees or winds exceed 15 mph. Please confirm the required completion period and whether weather-related extensions will be granted when these specification limitations prevent roofing operations. Response: The required completion period is as listed. Any weather modifications the may be needed will be handled when such delays occur. Typical weather delays are included in the performance period.

17. Please confirm whether the State apprenticeship requirements apply to the roofing, sheet-metal, mechanical, electrical, and welding work. The apprenticeship certification box in SC-

6.21 is checked, although the stated project estimate is below $1 million. Response: This box was accidentally checked. The State Apprenticeship requirement is not required for this project.

18. Please confirm whether Buy Clean Colorado requirements apply and identify which roofing, structural-steel, plywood, and sheet-metal products require Environmental Product Declarations. Response: If the successful Bid is greater than $500,000 a waiver will be submitted for Buy Clean Colorado as none of the plywood or steel will have a cost greater than $50,000. The only items on the current EPD list are plywood and steel.

19. The Advertisement states that performance and payment bonds must each be at least 50 percent of the Contract Sum, while Article 26 appears to require bonds for the full Contract Sum. Please confirm the required bond amounts. Response: That reference is that if the contract is over $150,000.00 than the payment and performance bonds not less that 50% of the contract sum and cost associated can be included in the contractors bid. The awarded vendor’s requirement is that the performance and labor and material bonds required by contract are at 100% of contract sum.

20. Please provide the SBP-6.18 Direct Labor Burden Calculation form required with the bid but not included in the Project Manual. Also confirm that this is a Base Bid only with no alternates, allowances, or unit prices. Response: Yes, SBP-6.18 will be required by the apparent low bidder and has been attached to the addendum.

21. Please provide the construction-phase badging and access requirements, including processing time, personnel eligibility, escort requirements, delivery procedures, approved construction gate, and procedures if a worker is denied a badge. Response: All personal that work on Buckley SFB are required to go through a background check. It is the responsibility of the contractor to vet employees to ensure they can pass a background check. If a worker is denied a badge, they will not be able to gain access to the base and perform any work. A DBIDs will need to be completed for everyone entering the base for work, this takes 72 hrs. for approval before the individual can arrive at the visitor center and receive a long-term badge to the duration of the project. If entering Buckley SFB in a personal owner vehicle, they can enter through the Mississippi or 6th Ave gates. If they will be driving a commercial vehicle, they will be required to enter through LVIP which is located off 6th Ave. for a full search of the vehicle. This process takes longer than the standard gate entry and is dependent on the demand of contractors entering the base for that day. All deliveries will also us the LVIP gate and process. The government will assist in assigning escorts for the project based off the selected contractors project managers’ recommendation. These escort will be required to attend a short training and assume the responsibilities of the escorting requirements.

22. Section 01 50 00 appears to require a six-foot chain-link enclosure with barbed wire around the construction site, while R1.0 specifically requires fencing around the dumpsters. Please confirm the required fencing limits. Response: No construction fencing is required at the work will take place on a secure facility.

23. R1.0 requires a commercial truck sweeper multiple times daily for FOD control. Please confirm the areas to be swept, the minimum daily frequency, and whether this requirement applies throughout the entire project or only during work adjacent to the flightline.

Response: It’s required to always keep the flight line clear of any debris throughout the entire project. It’s also anticipated to keep the surrounding areas of the building clear of debris as the site adjoins an active construction site.
