Project Development Workflow Tasks (PDWT)

Part 3 - Identify Project Need and Project Initiation Document

II. Project Initiation Document

A. Define Transportation Need and Assess Site (150.05) - Obtain and Review Existing Reports, Studies and Mapping (150.05.05)

P23. Review Related or Adjacent Studies

Important background information can provide a historic perspective to the current proposal and can often be obtained from related or adjacent studies of past or current projects. The project engineer should keep in mind that every existing highway has a past history, and is thus likely to have past project records. Locating the records may, however, prove to be difficult.

Information from past or current projects can be obtained from many sources such as the following:

  • The District Record’s Management Officer may be contacted for assistance in locating archived Project History Files.
  • The District Program/Project Management Database can help identify other State projects including Minor and Maintenance projects falling within the same or nearby limits.
  • The District Status of Projects should also be reviewed for other proposed or programmed projects overlapping, within or adjacent to the project.
  • The Program/Project Management or Advance Planning Division may also be able to provide completed PID documents for projects that were not programmed (shelved/inactive projects).

In addition, the project engineers must make a thorough search for other locally developed projects within the vicinity. The Local Assistance Office can help the project engineer to become aware of other locally developed projects that may otherwise not show up in the district’s Project Databases.

The Systems Planning section of a PSR document provides and opportunity to discuss the considerations and consistency of the proposed project with statewide planning efforts found in the District System Management Plan and the Transportation Concept Report. Planning section of a PSSR is used to identify other related projects. It is critical to address in the PID how the proposed project will impact or be impacted by other projects in the vicinity. During the PID Phase, particular emphasis must be placed on traffic handling in situations when another project involves concurrent or nearby construction.
