10.7.2 Plan Set Requirements
The following, at a minimum, should be included with all 3R PS&E submissions:
- Design speed for the project (same as shown on page 3 of form 1002);
- Existing and proposed typical sections showing lane and shoulder widths, obstruction clearances, and bridge widths;
- Existing and proposed information on bridge rails and the structural capacity of all structures;
- Plan and profile sheets detailing the proposed horizontal alignment, superelevation, and vertical alignment if the existing grade or horizontal alignment are changed at specific locations. If the scope of work closely follows the existing grade line (e.g., overlaying, widening, etc), then data from previous plans or a summary sheet (tabular presentation) showing horizontal curve data and vertical curve data may be used. The plans could also be a combination of proposed realignment plan & profile sheets at specific locations and a summary sheet of existing geometry for the remainder of the project; and
- Existing and proposed information on safety appurtenances (such as guard fence and safety end treatments).
The summary sheet indicated above should be signed and sealed by the responsible engineer with a note documenting that the appropriate engineering analysis was accomplished. The note will vary depending on the analysis completed. The following is an example of a note that might be used:
"Existing bridge rails are constructed in and structures meet HS loading. This project meets the basic safety requirements of the 3R design criteria. Guard fence (including connection to structures, post spacing and end treatments), signing, and pavement markings meet current standards. Cross drainage culverts, parallel culverts, mailbox supports, luminaire supports, and sign supports within the required clear zone of feet have been safety treated or are being upgraded to standards.”
