What is the combination of competitive procedures designed to obtain the benefits of sealed bidding when adequate specifications are not available?

The combination of competitive procedures designed to obtain the benefits of sealed bidding when adequate specifications are not available is indeed two-step sealed bidding. This approach involves two distinct stages.

In the first step, potential bidders submit technical proposals without pricing information. This allows the procuring agency to evaluate the technical competence of each bidder and identify any required changes to the specifications. After this evaluation, the agency may finalize the specifications based on feedback from the bidders.

In the second step, the same bidders are invited to submit sealed bids based on the final specifications. This process utilizes the competitive nature of sealed bidding while allowing for input and refinement of the project's requirements when initial specifications may lack clarity.

This method is particularly beneficial in complex procurements where precise specifications are essential for fair competition yet not initially available. It encourages innovation and diverse solutions from bidders, ensuring that the final proposals align closely with the agency's needs while maintaining a fair competitive environment.
