A best practice tool to enhance design-build best-value procurements are stipends, yet there is very little literature dedicated to this topic. Cited benefits of stipends include incentivizing the level of effort put forth by proposers in preparing their technical proposal, encouraging the number of proposers and thereby increasing competition, and mitigating risk.

This paper investigates four aspects of stipends: (1) stipend value and calculation processes; (2) impact on a contractor's decision to propose; (3) impact of stipend amount on an offeror's proposal development, and (4) stipends' ability to aid agencies in achieving best value for highway construction projects.

Agencies should use stipends when proposal costs are expected to be high and should estimate the stipend amount on a project-by-project basis.
