Highway administrators, engineers, and researchers often face problems for which information already exists, either in documented form or as undocumented experience and practice. This information may be fragmented, scattered, and unevaluated. As a consequence, full knowledge of what has been learned about a problem may not be brought to bear on its solution. Costly research findings may go unused, valuable experience may be overlooked, and due consideration may not be given to recommended practices for solving or alleviating the problem. This report of the Transportation Research Board summarizes available information on statewide highway letting programs, which are defined as a set of highway projects in advanced stages of design that have a target date for construction bid. This synthesis identifies those approaches, tools, and techniques used by state highway agencies (SHAs) in the management of letting programs; evaluates changes that influence letting schedules; identifies the impact of issues relevant to contract award that may influence the outcomes of specific lettings; and assesses SHA interest in data sharing initiatives relative to letting program management. This synthesis report contains information drawn from three primary sources: a review of the literature pertaining to letting program management conducted with a specific focus on processes and techniques; a survey questionnaire distributed to SHAs; and selected interviews with five SHAs, representing a cross section of agency size, to explore in greater detail the various approaches taken to develop and manage letting programs. |
