Project Development Workflow Tasks (PDWT)

Part 3 - Identify Project Need and Project Initiation Document

II. Project Initiation Document

E. Prepare and Approve PID (WBS 150.25) - Prepare Draft PID (WBS 150.25.05)

P75. Prepare Attachments

Attachments to PID documents are used as support of the information and conclusions contained within the PID, and help clarify the project proposals. Since there are many PID types, each type will have varying types of attachments. Appendices in the PDPM recommend the appropriate attachments for each of the various types of PIDs. Attachments must be of sufficient quality such that subsequent copies remain legible.

Attachments to the PID:

  • Must be legible.
  • Should be standard 8 ½ x 11 inch or 11 x 17 inch paper size. Odd size attachments are difficult to copy and slow down reproduction.
  • Maps should be oriented with the north direction facing up the page.
  • Should have an identification letter or number such as; Attachment A, B, C or 1, 2, 3.
  • Should be attached in the order in which reference is made within the PID.
  • Should be listed at the end of the PID text.
  • Should use shading or patterns rather than color.
  • Must never contain specific traffic accident reports.
  • Should be referred to within the text of the PID.
  • DES Scoping Checklist

Recommended Map/Drawing Attachments:

  • Area of Interest Map (Location Map/Vicinity Map)
  • Plan View (Layout) or Strip Map
  • Typical Cross Section
  • Highway Inventory Photos
