Comment Classification: Unclassified (U)

The Bidding Schedule identifies an estimated excavation quantity of 1,220,000 CY. Section 31 23 00 states that payment quantities will be determined by the Government using the average-end-area method based upon the Contractor's Pre-Grading Survey and actual final grade. Please confirm whether 1,220,000 CY represents the Government's current calculated estimate based on the March 2026 survey and contract grading limits. Please also provide the Government's quantity calculation, existing/proposed digital terrain models, cross-section quantity files, or other supporting earthwork quantity data used to establish the 1,220,000 CY bid quantity, if available.

On: Aug 25 2026.

Government Response. . The estimated excavation quantity of 1,220,000 CY identified in the Bidding Schedule

(CLIN 0001) represents the Government's estimate and is based on March 2026 survey.

However, the contract documents stipulate that the final payment quantity will not be based on this initial estimate.

Instead, the final paid quantity will be determined using the average-end-area method based upon the Contractor's pre-grading survey and the actual final grade. On: Sep 08 2026

11978283 General Section 31 23 00.00 20, Paragraph 3.3.1; Section 02 21 10.00 12 Comment Classification: Unclassified (U)

The specifications indicate that grades shown on the drawings are prior to clearing and grubbing and that, following clearing and grubbing, the Contractor shall field verify the new grade elevations. This verification survey becomes the original survey for determining excavation quantities. Please confirm that the Contractor will be paid for the actual quantity calculated between the approved post-clearing Pre-Grading Survey and accepted final grade, regardless of whether the actual quantity is greater or less than the estimated 1,220,000 CY. Please also confirm that no excavation may begin until the Government has reviewed and accepted the Pre-Grading Survey that will establish the pay quantity baseline.

On: Aug 25 2026.

Government Response. . Yes, the contractor is paid on actual quantity calculated. No excavation may begin until the Pre-Grading Survey has been approved by the Government. On: Sep 08 2026 Current Request Status: Request Closed

11978287 General Section 02 21 10.00 12; Section 31 23 00.00 20 Comment Classification: Unclassified (U)

Please identify the anticipated Government review period for the Pre-Grading Survey and clarify the procedure to be followed if the Government and Contractor disagree regarding the pre-grading surface, final surface, or calculated excavation quantity.

Please confirm whether a mutually accepted quantity surface or signed quantity computation will be established before excavation progresses beyond initial grading.

On: Aug 25 2026.

Government Response. . Review will be completed as soon as practicable, but the Government will be allowed up to 30 calendar days for review and return of each submittal.

If the contractor and the Contracting Officer cannot agree on the survey elevations, the Government's calculation will be provisionally used. If the contractor does not agree with the Government's computation, the "Disputes" clause of the contract can be invoked.

The process does not mandate that all excavation must cease until a initial quantity is signed off on; rather, it relies on the accepted pre-grade survey as the established starting point. On: Sep 08 2026

Comment Classification: Unclassified (U)

The contract requires excavated material generated by CDF-22 degradation to be used as fill, first within CDF-22 and then within FDDA-22, and prohibits borrow excavation outside the grading limits.

Specifically, please confirm whether the Government would furnish additional borrow, authorize an outside borrow source by modification, revise the required grades, or otherwise adjust the work.

On: Aug 25 2026.

Government Response. . No additional borrow material will be provided. The contractor shall utilize all currently available material to bring CDF-22 to final grade first prior to placing material in FDDA-22. If the volume of available material is insufficient to achieve final grade across the entire site, the contractor shall bring as much of the site to final grade as possible using only the currently available borrow.
