The Government will award a Firm-Fixed-Price Purchase Order to the responsible offeror providing the Lowest Price Technically Acceptable solution. Evaluation ranks quotes by total price, then sequentially evaluates technical acceptability beginning with the lowest-priced quote. A quote receives "Acceptable" rating only if it clearly meets all minimum requirements; any failing quote is "Unacceptable." If the lowest-priced quote is technically acceptable and price is determined fair and reasonable, award is made and evaluation concludes. Past performance is reviewed solely for responsibility determination; offerors lacking relevant past performance are neither favored nor disfavored. A 12-month warranty applies from delivery date. Prices must be firm for 30 calendar days from receipt and include all-inclusive unit cost, materials, and transportation on FOB Destination basis.
