This is a sole source requirement for the repair of two specific generator units, with the government stating it lacks the data to contract with anyone other than the current source. The induction period for the initial units is 365 calendar days from award, with a government option to extend it by an additional 365 days for a total of two years. The contractor must propose option pricing for up to 10 units over the entire contract period, with separate pricing required for the second year if prices will change. The total contract value will be calculated using the highest proposed unit price multiplied by the maximum number of units. The performance location is associated with NAVSUP WSS Philadelphia.
