This RFQ is for the purchase of one initial unit of a specific spare part, with options for up to 10 total units over the contract period. The induction period for the initial units is 365 days from award, which the Government may extend by an additional 365 days. The total contract value will be calculated using the highest proposed unit price multiplied by the maximum number of units. These items require Government Source Approval, and unapproved sources must submit specific information with their proposal to be considered. The contract will be awarded under the terms of an existing Basic Ordering Agreement.
