AIP PROJECT NO. 3-51-0041-026-2025

DELTA PROJECT NO. 24052

QUESTIONS AND ANSWERS

1. QUESTION: If the bid is held until October, will the bid be awarded prior?

ANSWER: Yes. The County will award the project based on the Alternate selected. A

Notice of Award will be executed at that time. The awarded contractor will separately receive the signed contract on or before October 20, 2026.

Information regarding the bid bond is referenced in the Invitation to Bid.

2. QUESTION: When will the notice to proceed (NTP) be issued?

ANSWER: Two separate NTPs will be issued; one for the administrative start and procurement of materials and one for the start of onsite construction. The procurement NTP will be issued closely following final funding approval in October 2026.

3. QUESTION: What is the construction contract time and what are the liquidated damages?

ANSWER: The total contract time is 165 calendar days. Contract time will begin following the construction notice to proceed. The overall contract has

$3,000 per day of liquidated damages. The work phase that will affect access to the existing hangar (Phase A1) will have $3,000 per day of liquidated damages.

4. QUESTION: When is construction expected to start?

ANSWER: The County anticipates that administrative work will occur in Fall 2026 with construction in Spring 2027. The County’s intent is to allow flexibility for the Contractor to supply the building materials without impact to the construction. If the Contractor requests to start site work in Fall 2026, in anticipation of having the site prepared for the building materials delivery, the County will consider a full notice to proceed in Fall 2026. This will start the 165 Calendar Day Contract Time. A temporary stop work order would need to be issued to stop contract time for winter months. Any cost to temporarily stabilize the site during a stop work order would be at the

Contractor’s cost.

5. QUESTION: The building materials have a long lead time to approve and procure. What work may be completed prior to the start of construction time?

ANSWER: The 165 Calendar Day Contract Time is applicable only to on-site construction (tree clearing, earthwork, erosion and sediment control, drainage, foundation, building erection, paving, and electrical installation).

The final design, shop drawings, permitting, and material delivery period is

NOT included in the 165 Calendar Day period. The contractor may complete all shop drawings, and deliver materials to the project site, prior to construction.

6. QUESTION: What are the site work limits for Alternates 2 & 3?

ANSWER: Except for a portion of pavement on the plan-left side of the proposed building, the site work will end with the face of the selected building. In alternates 2 & 3, the areas not receiving full build out will be graded to final elevations and permanently stabilized. The limits of the alternates can be viewed on Sheet 8.

ANSWER: No. Only the pedestrian doors will be considered accessible entrances.

ANSWER: The Contractor will be responsible for final building, foundation, and electrical design, to be signed and sealed by a professional engineer.

9. QUESTION: What is the minimum foundation depth?
