Question: 
Can I ensure the use of my specialized subcontractors when awarding to a prime?

Use of subcontractors is at the discretion of the prime contract holder, subject to advance consent to subcontract provisions as provided in the FAR. If you have specialized requirements, they should be included in your SOW and, if those requirements necessitate the support of a specific subcontractor, it would be incumbent upon the prime to make the necessary business arrangements with that party in order to improve their chances of obtaining an award.
