In the case of multiple contract awards on the same day, what is the priority order for the delivery dates?

The priority order for delivery dates in cases involving multiple contract awards on the same day is determined by the urgency of the required delivery. The designation "DX" indicates a priority delivery which is crucial for national defense or emergencies. Consequently, contracts designated as "DX" take precedence over others due to their critical nature.

Following "DX," contracts categorized as "DO" (Delivery Order) are the next in line for priority. If there are multiple DO contracts, these will typically be treated equally in terms of priority. Lastly, unrated contracts, which lack a specific urgency designation, are considered last in this hierarchy.

Thus, the correct sequence of priority is "DX," followed by both "DO's," and finally the "Unrated" contracts. This order ensures that the most urgent needs are addressed first, aligning with the principles of efficient contract management and national priorities.
