1. Q: Does Lead paint on tunnel metal entrances need to be abated/removed, or can demolition contractor dispose of the metal with paint intact?

A: MODNR states that as long as product painted lead paint is disposed of in a certified lead paint dump, the paint does not need to be abated.

3. Q: Does roof asbestos get manually removed prior to demolition? Or can it be demolished with the building and properly disposed of by the demo contractor?

4. Q: Is the abatement contractor to provide daily air monitoring and or clearances air sampling, or will the base be providing this service in house?

A: Yes if it is properly prepped for that purpose. After abatement, concrete/steel may be used as appropriate fill providing voids are filled to inhibit settling.

22. Q: Please provide a grading plan. A statement was made as to establishing grades that can accommodate a plane overshooting the runway. Please provide specific requirements for final grading in support of drainage and other requirements.

A: Given the location, overshooting is not an issue. The Government requires the contractor to generate a grading plan. The SOW attached to the solicitation is the requirement for this effort. If this comment was made, it was in error and should be disregarded.

Does this include removal of the existing medium voltage switches and any installation of new cable to redirect power feeds?

A: Disconnect at transformer North of security gate as stated in the SOW. Switches can remain and no redirection of power feeds is required.

27. Q: What is the general location of the fiber splices to be completed and the new vault set per SOW? How many fiber pairs enter the area? What is the configuration of the splice regarding the amount of fiber to leave the area?

A: From the existing manhole West of the Western-most tunnel on the Southern face of the S-6 structure, two three-inch fiber-optic capable lines shall be placed (trenched in or directional bored) East between the S-6 structure and the asphalt flight-line staging area.

The two lines shall be trenched in or bored under/through the curb and existing asphalt on the Eastern asphalt ring-road. These two lines shall enter a suitable splice-box that will be located/placed East of the ring-road but not interfering with the existing lighting vault/conduit and the existing manhole. The location of the new splice vault shall be at the discretion of the WAFB CE department. Two lines will then be trenched in/directional bored to the existing splice vault just over 100 feet East of the NE corner of the asphalt ring-road.

28. Q: Due to the proximity of the taxiway, elevation and location of the demo site, and the winter prevailing winds, will a full height containment fence be required during building demolition activities?

A: A 6-foot high chain-link fence is acceptable so winds can move through but fence will still prevent debris to move outside of the work area. The area shall be policed regularly to minimize FOD (foreign object debris) from entering the flight line. This is critical and will be inspected daily. Base FOD guidance will be provided at award.

29. Q: Will the contractor be responsible for running potential outages for all utility demolition/capping activities?

A: Outages will be coordinated with the Government.

30. Q: Line item D in the scope of work states “demolition (service work), grading and drainage (construction which may require the introduction of additional “fill” materials to meet said drainage requirements).” There was one wage decision posted with the solicitation that was regarding service work wage rates. Will the project be encompassed in the service wage rate in its entirety? Or will the contractor be responsible for defining the different scopes of work and adjusting certified payrolls from service to construction rates?

A: Per FAR 37.301, Labor Standards, this effort is governed by 41 U.S.C.chapter 67. This is a service contract effort only and is subject to SCA WD 2015-5089 rev 13 dated 18 May 2020.

31. Q: During the seeding process, will the contractor be required to drill the seed due to the project location and the potential for the traditional mulching activities to blow away and create a bird hazard?

A: This is means and methods to some degree, slit seeding, drilling, and hydro-seeding are all acceptable.

32. Q: Since as-built drawings have not been released, we ask for additional time to review and ask questions based on those documents. Would the Government allow an extension of 4 days from release of as-builts to ask additional questions and 14 days from release of as-builts to return the proposal.

A: Additional time was given when as-builts were posted to beta.SAM.gov. The solicitation has been extended, please see the amendment posting for extension information.

33. Q: Ahrens Contracting, Inc. would like clarification of final site grading for FA4625-20-R-

1006 Bldg. S-6 (B-6) Demolition.
