The US Department of Transportation released a guidance document on completing a benefit-cost analysis (BCA) associated with BUILD grant applications. The PDF document is here.
DOT notes the information provided in applicant BCAs will be used to help ensure that the available funding under the programs is devoted to projects that provide substantial economic benefits to users and the nation as a whole, relative to the resources required to implement those projects. DOT staff has noted in application debriefs that applicants should utilize BCA information within the application narrative to strengthen the case for the project rather keep the BCA and the narrative separate.
