(c) The contracting officer shall, when contracting by negotiation, insert in solicitations and contracts containing the clause at FAR 52.219-25, Small Disadvantaged Business Participation Program-Disadvantaged Status and Reporting, a clause substantially the same as the clause at FAR 52.219-26, Small Disadvantaged Business Participation Program-Incentive Subcontracting, when authorized (see FAR 19.1203). The contracting officer may include an award fee provision in lieu of the incentive; in such cases, however, the contracting officer shall not use the clause at FAR 52.219-26. Do not use award fee provisions in contracts with contractors that have comprehensive subcontracting plans approved under the test program described in 219.702.
