This opportunity is for the repair of a TITRATOR under a firm-fixed-price contract, with performance required at the contractor's facility. The government is seeking a specific Repair Turnaround Time (RTAT), and failure to meet the required RTAT will result in a price reduction per unit per month. All transportation is handled by the US Navy, and Government Source Inspection (GSI) is required. The contract includes a 100% option quantity that may be exercised within 365 days of award, with the same delivery turnaround as the base items. Offerors must provide pricing, RTAT, and indicate whether they accept the option quantity.
