This is a sole source requirement for the repair of one specific generator unit, with the government stating it lacks the data to contract with any source other than the current one. The contract includes an initial induction period of 365 days from award, which the government can extend by an additional 365 days. The contractor must propose option pricing for up to 10 total units over the contract period, with separate pricing required for the second year if prices change. The total contract value will be calculated using the highest proposed unit price multiplied by the maximum number of units. Offers from non-approved sources must include a complete source approval submission to be considered.
