NCHRP Program Cycle
Submittal & Evaluation
• NCHRP solicits problem statements from authorized sources: DOTs, AASHTO Committees/Subcommittees, and FHWA (July-September)
• FHWA and NCHRP evaluation panels and staff evaluate problem statements
• SCOR and RAC rate the candidates in a mail ballot to set priority for the SCOR meeting in March
• NCHRP sends a summary report to the SCOR
NCHRP Program Cycle
Formulation & Approval
• SCOR meets to formulate the NCHRP Program (late March)
• FHWA approves of conformance with Federal-aid requirements
• SCOR sends a report to the AASHTO Board of Directors requesting approval of the projects
• AASHTO refers program to the NAS for administration
• NAS reviews for acceptance
NCHRP Program Cycle
Execution
• NCHRP solicits panel nominations (May-June)
• NCHRP appoints panel members
• Panel prepares RFP (July-September)
• NCHRP solicits proposals
• Panel reviews the proposals and makes recommendation for award of contract
• NCHRP negotiates and executes a contract
• NCHRP administers the project
