... 8 NCHRP LRD 90 dence of bid protests for best value procurement. On the other hand, the exibility that allowed the procuring agency in a best value procurement makes it dicult for protesters to argue that the agency failed to comply with applicable requirements, so long as the evaluators comply with the requirements specied in the RFP and applicable law.

... NCHRP LRD 90 9 561: Best-Value Procurement Methods for Highway Construction Projects describes the four concepts (best value parameters, evaluation criteria, evaluation rating system, and award algorithms) that are shared in common by best value procurements for multiple highway construction projects and provide a foundation for the best value selection process, as shown in Figure 4.

... 10 NCHRP LRD 90 considered in the evaluation process. An agency may further include a formal ATC process in the procurement, whereby proposers are permitted to submit, for agency approval in advance of the preparation of the proposal, proposed deviations from the technical requirements for the project that may be included in the proposal.28 In many cases, proposed design solutions are consistent with the contract specications and do not require the submittal of an ATC.

NCHRP LRD 90 13 the likelihood of proposer challenges to award decisions. e evaluators in a best value procurement process rate price along with more subjective, non-price factors, thus potentially leading to allegations of unfairness.34 Considerable thought and analysis should be used in forming these teams, as well as in training evaluators regarding the criteria and process for evaluations to avoid claims of bias or inconsistency.

... NCHRP LRD 90 15 study, including internally developed evaluation rating systems, which may be: • Adjectival-based rating systems with consensus rating or other methods of determining rankings for each proposal in each criterion. In some cases, evaluators assign adjectival rates that are later converted to scores.

... 16 NCHRP LRD 90 Satisficing is rating system, also known as "Go/No Go" is the simplest and easiest among all evaluation rating systems. Evaluators establish minimum standards for each evaluation criterion in the form of a statement of the minimum level of compliance that must be met by a proposal to be considered acceptable.

Fixed Budget–Best Proposal is value unit price algorithm is a variation of best value procurement procedure in which an agency stipulates the contract price in the proposal request, as well as the qualitative and technical evaluation factors for project elements upon which the selection will be determined.

... 22 NCHRP LRD 90 should carefully consider dierent scenarios to ensure that the formula will produce the expected result. Quantitative Cost–Technical Tradeoff In this value unit price award algorithm, the agency uses a formula to assign a numerical value to the incremental dierence between the highest technical score and other technical scores.
