Airfield Paving and Repair Solicitation

Questions and Answers #2

Q 1. Is there any existing pavement data available?

a. Concrete Thickness

A 1a. Thickness ranges from 8 to 24 inches

b. Asphalt Thickness

A 1b. Thickness ranges from 2 to 9 inches

Q 2. Can you provide an estimation for the typical proposed repair sizes?

a. Bituminous asphalt

A 2a. Typical width will be 25’ wide and length will vary up to 2,000’

b. Partial Depth Repair

A 2b. 2” minimum in depth. Typical width 12” and length 6’ to 8’

c. Random Slab Replacement A 2c. 12’ X 12’; 15’ X 15’; 20’ X 20’; 24’ X 24’; 25’ X 25’. Thicknesses vary 8” to 24”

Q 3. Project Specifications require surface smoothness requirements using a straight edge and profilographing. Since this is a repair project fixing existing pavement, the existing conditions may not allow for the pavements smoothness requirements to be meet (faulting, spalling, heaving, etc…). Will these specifications be waved?

A 3. No, the specifications will not be waived. The specifications take the existing conditions into account.

Q 4. The definition of a “lot” seems to me more defined for a new pavement rather than pavement repairs. I am assuming the repair areas will be smaller in size than the defined “lots”. Can you please provide a better definition for lot size?

A 4. For concrete from the specifications on page 118, “A lot will be equal to one shift of production not to exceed 750 cubic yards.” Therefore a lot of concrete can be between 1 and 750 cubic yards.

For asphalt from the specifications on page 92, “A standard lot for all requirements will be equal to 500 short tons.”

Q 5. Is there any additional information available for the proposed required traffic control?

a. Closure Durations

A 5a. The duration of the closure will be the shortest time required to complete the project i.e.

construction time, curing time, restriping time, then reopen.

b. Closure types & Lengths A 5b. The work area will be completely closed, but the rest of the airfield will remain open. The length will vary depending on the size of the area being worked on.

c. Will low profile barriers with flashers be required?

A 5c. Yes, in some areas they will be required as well as a drum fence.

Q 6. We are interested in clarification of an item within 52.219-14 Limitations on Subcontracting, specifically item 3) General construction, which states:

Questions and Answers #2 The concern will perform at least 15% of the cost of the contract, not including the cost of materials, with its own employees.

a. How is the 15% cost calculated?

b. With projects that have high material cost / large material component to them, will the 15% requirement be difficult to achieve?

A 6a. In accordance with FAR 52.219-14, the 15% will be calculated based on the cost of the contract, not including the cost of materials.

A 6b. The difficulty of achieving the 15% requirement will be determined by the contractor, and based on the contractor's bidding strategy for such projects; as a firm-fixed-price contract, the responsibility of performance within the terms and specifications of the contract rests on the contractor regardless of difficulty level for such endeavors. When determining whether the 15% is met, keep in mind that while some orders may be difficult to meet 15%, as it's based on the contract, other projects/task orders could well exceed the 15%.
