This rulemaking would revise and update regulations governing the procurement, management, and administration of engineering- and design-related services directly related to a highway construction project and reimbursed with Federal-aid highway program funding. To comply with statutory amendments, this rulemaking would remove all references to alternative or equivalent procedures contained in the existing regulations. This rulemaking proposes to revise existing small purchase procurement procedures to reflect an increase in the Federal threshold. This rulemaking would also address certain findings and recommendations contained in a 2008 Government Accountability Office regarding increased State DOT reliance on consultants and a 2009 DOT Office of the Inspector General audit regarding consultant indirect costs. This rulemaking would clarify existing Federal requirements in support of enhancing consistency with other Federal laws and applicable regulations, and addressing evolutions in industry practices to improve the procurement, management, and administration of consultant services.
