You must include the requirements for technical proposals and price proposals in the phase-two solicitation. All factors and significant subfactors that will affect contract award and their relative importance must be stated clearly in the solicitation. Use your own procedures for the solicitation as long as it complies the requirements of this part.

Alternate technical concept proposals may supplement, but not substitute for base proposals that respond to the RFP requirements.
