Questions submitted to CE 8/6/2025:

1. For the purpose of fair bidding, can The government provide a typical section for concrete pavement based on Dyess AFB standards for inside airfield areas and past projects solutions?

- Typical pavement section not available. Pavement section should be designed for ground equipment list provided and soil boring provided.

2. It is the intent of the government to use the proposed parking pad only for the mentioned ground equipment, or will also be designed and built to carry heavy bombers and other aircraft at any given moment in the future?

- The proposed AGE parking pad will not carry any aircraft. The pavement should be designed for the ground equipment provided.

3. The statement of work, page 3, paragraph 3.5.3 reads: The concrete shall have a minimum thickness of 8 inches. From past projects experience in Dyess AFB, for the last 20 years the construction of aprons and taxiways have included a 19” Concrete Slab panel on top of 6” RDM gravel layer and 6” mud slab. Please clarify if these standards also apply to the current project.

- The pavement section is not rated for aircraft traffic so past standards do not apply.

4. In reviewing the statement of work and specifications provided it is not specifically mandated the use of 650flex concrete for construction of concrete panels. From past projects experience in Dyess AFB, for the last 20 years the construction of aprons and taxiways has specified the use of 650flex concrete for all areas inside the airfield. Please clarify if this standard also applies to the current project.

- Yes. Specification Section 32 13 13.03 PCC Construction for Street Pavements Para. 2.2.1.1 Flexural Strength requires a minimum of 650 PSI flexural

5. In reviewing the statement of work and specifications provided it is not specifically mandated the use of #5 rebar @ 6” OCEW for the construction of all concrete panels. From past projects experience in Dyess AFB, for the last 20 years the construction of aprons and taxiways has specified the use #5 rebar @ 6” OCEW for all areas inside the airfield. Please clarify if this standard also applies to the current project.

- Reinforcement should be designed for the ground equipment list/pavement section.

6. Due to the new AI facility that is being built in Abilene, and the huge amount of resources that it demands, rentals and hotels are close to impossible to reach. Can the government provide assistance with any kind of lodging inside the base for this project?

- No known lodging available on base.

7. Due to the expansion and general growth of all City of Abilene there are big constraints for the dumping of construction spoils. Can the government allocate an area to permanently stockpile all construction spoils from this project?

- Permanent stockpiles are not permitted on Dyess AFB. All spoils must be removed in accordance to specifications and city, state, and federal regulations.

8. Does the government contemplate the construction of APU slabs for B1 bombers inside proposed concrete panels for future use?

9. Does the government contemplate the installation of moorings in proposed concrete panels for future use?

10. Does the government contemplate the installation of grounding system in proposed concrete panels for future use?

11. Please let us know what the specified class for reinforced concrete pipe is to be used in the current project.

- Class 3 has been used on Dyes AFB before. The reinforced concrete pipe should be designed for the provided traffic pattern and pavement section.

12. Will the adjacent building (B5020) remain operational during construction activities? If yes, will the contractor be required to maintain access to the areas in between the building and construction site? If yes, will the contractor be required to do phasing of the schedule of the work to allow full-time access to the building?

- Yes. The airfield and all supporting facilities will remain operational. No phasing required.

The contractor shall yield to all aircraft traffic.

13. As per provided conceptual plans, concrete panels shall be 12.5’x12.5’. Most of the concrete panels built in the airfield area are 25’x25. Please confirm concrete panel dimensions for the current project that are required by the government.

- The conceptual joint spacing is based on a minimum slab thickness of 8”. The joint plan should be designed according to designer’s pavement thickness and layout.

14. We have concerns about the bad quality of the existing subsoil in current grass areas. As per provided specifications “Compact subgrade for pavements to at least 100 percentage laboratory maximum density for the depth below the surface of the pavement shown.” If the embankment under the subgrade is poor-quality soil material, it will affect the compaction of the subgrade. We might be facing a huge amount of over-excavation and embankment construction with imported suitable soil. For the purpose of bidding, can the government provide a geotechnical report of cores inside the proposed jobsite area?

15. Please let us know if proposed trench drain shall be airfield heavy rated.

- Inlets should be rated for ground equipment list provided.

16. Please let us know if proposed junction box shall be airfield heavy rated.

17. Please let us know if proposed inlets shall be airfield heavy rated.

18. Please let us know if proposed inlets in sod areas shall be airfield heavy rated.
