Amendment 0001 Solicitation 140FHR25R0001 Questions and Responses:

1. Do you require the drawings to have a Professional Engineering Stamp?

Yes

2. Can the bid due date be extended to the end of January? With the holidays right around the corner, we would need more time to develop the bid information and the technical section.

The solicitation will be extended to 1/28/2025.

3. Can the equipment delivery date be extended to at least 180 working days instead of 140 days upon contract award? Once a PO is provided, we need to allow time for submittal development, submittal approval, receipt of downpayment, prior to even starting production of the equipment.

The delivery date will be extended to 200 days from the contract award.

4. Are you open to staggered delivery of equipment to the hatchery site/ over a couple months?

A single delivery is preferred; however, a staggered delivery may be considered with proper justification. Please include a detailed delivery plan with your documentation.
