This is to certify that the Office of Contracting and Procurement allocated $10,000.00 in its
FY2025 budget to cover potential costs that may be incurred if a minimum order is not achieved
for the District of Columbia Supply Schedule (DCSS) contracts.
Each DCSS contract has been established as an indefinite delivery/indefinite quantity (]DIQ)
contract, and agencies may place orders against each contract by means of an individual Task
Order (TO) or delivery order (DO). If no orders are placed against a DCSS contract, pursuant to
the DCSS Terms and Conditions, clause 5, the District guarantees the minimum order for each
contract in the amount of $10.00 for the base year and four option years. Any additional orders
placed on the DCSS contracts will be encumbered by the ordering agency prior to issuance.
There are approximately 420 contractors on the DCSS, and it is estimated that $ I 0,000.00 would
be sufficient to cover the possibility of having to pay $ I 0.00, upon request, to multiple
contractors.
