The contract includes an option for the government to increase the quantity by 100% within 180 days of award, with the same delivery terms. A key requirement is that the contractor must have facilities capable of performing Government Source Inspection (GSI). The performance location is not explicitly stated, but shipping and inspection instructions reference contractor and subcontractor CAGE codes, indicating work is performed at the contractor's facility.
