This is a sole source requirement for the repair of one specific multifunction unit, where the government lacks the data to contract with any source other than the current one. The induction period for the initial unit is 365 calendar days from award, with a possible one-year extension, and the contractor must propose option pricing for up to 10 total units over the contract period. Offers from non-approved sources must include a complete source approval submission to be considered. The performance location is NAVSUP WSS Philadelphia. For threshold purposes, the total contract value will be calculated using the highest proposed unit price multiplied by the maximum of 10 units.
