  1. CE303: Introduction to Construction Blueprint Lab

  2. Highway Plan Reading

  3. Typical Sheets • Sheet 1: Title Sheet • Sheet 1A: Project Location Map • Sheet 1B: Right of Way Information • Sheet 1C: Revision Data • Sheet 1D: Hydrology Information • Sheet 2: Typical Sections • Sheet 3: Plan Sheets • Sheet 3A: Profile Sheets These are only typical sheets, and are not standards for all states. For example, the INDOT plans used in class differ slightly.

  4. Title Sheet Title and Desc. Project Limits Key Diagram Termini: Start and End stations Project No. FHA Region No. Notes Project Length State for Plans are intended Federal Aid Project No. State Project No. Sheet # Total Sheet #’s Functional Classification and Traffic Data

  5. Title Sheet • Revisions • Column with dates that the plans were revised • Typically located in the bottom right hand corner of the Title Sheet The Revisions for the INDOT plans are located on Sheet 2, the Information Sheet.

  6. Key Diagram • Located on the Title Sheet • General Plan View of Road • Contains the Termini of the project • Beginning and End Points

  7. Location Map • Orient project in relation to other features or existing roadways • Typically always oriented to the North

  8. Location Map

  9. Common Symbols US Route State Primary Highway Interstate Highway

  10. Plan Sheets • Consists of a Baseline/Centerline • Contains all Horizontal Measurements • Measurements Marked in Stations • Stations based on 100 ft. Measurements • Station Numbers Increase W to E and S to N

  11. Curves • Any point of roadway in which points of baseline do not form a straight line • Horizontal and Vertical Curves • Curve Information given on plan sheets • Angle, Tangent, Length, Radius, PC, PI…

  12. PI Δ T PT PC R PI: Point of Inflection PC: Point of Curvature T: Tangent PT: Point of Tangent R: Radius Δ: Deflection Angle

  13. Equality OLD NEW • Point along Baseline with 2 Station Numbers • Used when New alignments meet old alignments • No changes to undisturbed alignment

  14. Equality Symbol POT 218+15.80 B’k POT 219+07.17 Ah’d What is the distance between Stations 215+00 and 220+00? 215+00 220+00

  15. Profile View • Shows Vertical Alignment/curves of Roadway • Not symmetrical, i.e. different grades on each side • Vertically Exaggerated Scale • Contains Station Numbers • Elevations • Shows Existing and Finished Grade

  16. Proposed Alignment Existing Ground

  17. Cross Sections • Located on a Typical Section Sheet • Contains Details about Structure of the Pavement • Shows Cross Slope of Pavement Surface • Shows Drainage Ditch Slopes
