*REQUIRED DOCUMENTS

Each contractor providing a quote shall submit the following documents to include:

1. A completed and signed standard form SF1449 with unit prices for each line item.

2. Executed copies of any amendments (if applicable).

3. Completed FAR 52.212-3 Representations and Certifications unless otherwise completed in SAM.

4. Pictures of proposed equipment and Equipment Data Sheet

Award will be made for the technically acceptable item or combination of technically acceptable items that result in the lowest aggregate price to the Government.

Technical Acceptability: Technical Acceptability will be evaluated to determine an overall rating of “acceptable” or “unacceptable”. This will be determined by evaluating the ability of the quoter to provide a sound, compliant approach that meets all requirements and demonstrates a thorough knowledge and understanding of the Specification requirements. It is the contractor’s responsibility to ensure that their quotation clearly demonstrates their ability to perform these requirements. Technical acceptability will be defined as follows:

mailto:cheryl.copeland@navy.mil mailto:USFF_NNSY_C432@navy.mil mailto:cheryl.copeland@navy.mil

Technical Ratings

Rating Description

Acceptable Quote meets all of the requirements identified.

Unacceptable Quote does not meet all of the requirements identified.

Failure to meet any technical requirement for an item (or specification) will make the quotation unacceptable for that item (or that specification).

If an item (or specification) is technically unacceptable, its price will not be considered for award.

Price:

The estimated amount for each line item will be added together to determine the total estimated price which will become the evaluate price. Provide breakout for pricing as follows:

DAILY RATE

WEEKLY RATE

MONTHLY RATE

The vendor’s proposed price will be evaluated on the basis of price reasonableness. All prices must be considered fair and reasonable as determined by the Government. Price quote shall be held firm for sixty (60) days.

The completion and submission of the above items will constitute a quote and will be considered the vendor’s unconditional assent to the terms and conditions of this solicitation and any attachments and/or exhibits.

Failure to provide all of these documents by the required date and time may preclude a quotation from award consideration at the discretion of the Government.
