  1. Welcome to the International Right of Way Association’s Course 901 Engineering PlanDevelopment and Application

  2. Introductions Who you are. . . What you do . . . Where you work . . . How long . . .

  3. Objectives • Identify and Use Plan Information • Understand Engineering Terms • Explain Plans • Use Engineering Tools • Apply Principles to Your Work

  4. Schedule • Follow Participant’s Manual 8:00 – 8:30 Introductions, etc. 8:30 – 2:45 Use of Engineering Plans and Plan Development 2:45 – 3:45 Other Plans and Maps 3:45 – 4:15 Summary and Review 4:15 – 5:00 Exam

  5. Graphic Language ➢ Lines ➢ Graphs ➢ Charts ➢ Symbols Engineering Plans

  6. Right of Way Plans used by: • Appraiser • Negotiator • Attorney • Engineer/Surveyor • Value Property • Explain detailsAcquire Property • Present in Court • Legal Documents • Design & Construct

  7. Three View Concept Top View Side View End View Plan View Profile View Cross Section Length and Width Height and Length Width and Height Each View is Perpendicular to Others Gives 3 Dimensional Picture Of Project

  8. Plan View (Top View) • Existing Features - Dashed Line • Proposed Construction - Solid Line

  9. Plan View (Top View) • Property Information • Drawn to Scale

  10. Engineers Scale Inches divided into multiples of 10 per inch

  11. Architects Scale Divides feet into inches and fractions

  12. North Arrow - Orientation of Plan Three Norths - Geographic True North - Magnetic North - Datum North

  13. Centerline - Control Line ➢ Horizontal Direction of Project ➢ Deflection Angle Changes - Delta ()

  14. Compass Bearings • Four Cardinal (Main) Directions • ➢ “N” , “E”, “S”, & “W” • Quadrants (90°) • ➢ “NE” , “SE”, “SW”, & “NW”

  15. Compass Bearings Shows Direction of Centerline or Property line

  16. Stations • Marked in 100’, 100 m or 1000 m Intervals • Always Numbered Positive • Used for Reference and Location • Intermediate Points Called “+” (Plus) • Directions: “BK”, “AH”, “LT”, “RT”

  17. Exercise #1 - Utility Centerline 3962 +2126 N = 58°-30’ Sta 60+88  6088 2126’ PI Sta 39+62 N81°-45’E 60+88 81°-45’ -23°-15’ 1962’ 58° -30’ N23°-15’E  = 58°-30’, Rt 20+00 =2000 +1962 3962 39+62 POB, Sta 20+00 Scale: 1” = 500’

  18. Station Equations/Equalities • Used When Stations Not Continuous • Point has Two or More Station Numbers • ➢ One Back and One Ahead • Calculating Correct Distance Between Stations • ➢ Add Individual Segment Lengths

  19. Station Equations R/W NEW HIGHWAY C L R/W

  20. Highway & Railway Curves PI T T T - Tangent - Straight Section of Centerline PI - Point of Intersection - Delta Angle - Deflection Angle

  21. Simple Curve PC - Point of Curvature PI D PT PC PT - Point of Tangency L POC L - Length of Curve POT R - Radius R POC - Point on Curve D POT - Point on Tangent

  22. Reverse Curve Two Curves, Adjacent, Opposite Directions PRC PRC - Point of Reverse Curvature Has 2 PIs

  23. Compound Curve Two Curves, Adjacent, Same Direction PCC Different Radii PCC - Point of Compound Curvature

  24. Spiral Curve Constantly Changing Radius Spiral on Each End of a Simple Curve TS - Tangent to Spiral SC - Spiral to Curve CS - Curve to Spiral ST - Spiral to Tangent

  25. Degree of Curvature • Measured 100’ Along Centerline • Angle at center of arc 100’ D

  26. Degree of Curvature-D • Indicates Flatness/Sharpness of Curve • ➢ Small D - Large Radius • ➢ Large D - Small Radius • Examples: • ➢ 1° Curve Radius = 5,729.58’ • ➢ 10° Curve Radius = 572.96’

  27. Exercise #2 – Highway Centerline PI: 3962 -T = - 802 PI: 3962 (1463’) PC = 3160 + T = +802 Sta 31+60 PT = 4764 47+64 Sta 47+64 46+23 PC: 3160 + L = +1463 PT: 4623 31+60 Sta 46+23

  28. Offsets • PerpendicularDistance Right or Left • of Centerline ➢ Locate any Point off Centerline ➢ Use Radial Line on Curve 65’ Lt, Sta 14+50 P L (155’) 14+00 21+00 (650’) 90’ Rt, Sta 21+00  6502+ 1552= LENGTH = 668.2’

  29. Contours • Lines of Equal Elevation • Shows Shape and Slope of Land • Interval - Elevation Difference • Between Contour Lines

  30. Contours • Relative Spacing of Lines Indicates Slope • ➢ Close Lines = Steep Slope • Contours Point Upstream

  31. Contours

  32. Exercise #3 - Contours 50’ • 1. Map Scale? 1” = • 2. Contour Interval: • 3. Sidewalk Width: • 4. Elevation Difference: • 5. Ball Rolls: • 6. In Flood Plain: • 7. Elevation: • Equation: Saratoga = Bridge St • 9. Saratoga St. R/W: • 10: Bridge St. R/W: 1’ 8’ 1.2’ South 238 & 240 863 9+9 5 0+00 60’ 60’

  33. State Plane Coordinate System • Survey Control - Latitude & Longitude Converted to Coordinates • Establishes Precise Location • Four Datums: • ➢ Two Horizontal – NAD 27 & NAD 83 • ➢ Two Vertical – NGVD 29 & NAVD 88 • Zones - Depends on Size & Shape of State

  34. State Plane Coordinate System • Point Identified by Two Coordinates ➢ “X” is “Easting” ➢ “Y” is “Northing” • Vertical Control Surveys Establish Elevations • Advantages: ➢ Excellent Control over Large Areas ➢ Accurate Locations

  37. Profile View • Side View – (Length & Height) • Stations & Elevations on Centerline Only ➢ Existing – Dashed Line ➢ Proposed – Solid Line

  38. Profile View • Horizontal Scale same as Plan View • Vertical Scale exaggerated for Clarity • Datum - Reference Elevation • Bench Marks - Known Location & Elevation

  39. Profile View - Pipeline

  40. Profile View - Overhead Line

  41. Profile View - Highway

  42. Profile Grade Line/Point • Profile Grade Line - Stations & Final Elevations on Centerline • Profile Grade Point - Centerline Elevation at Specific Station

  43. Profile Grade Line • Percent Grade - Rise (+) or Fall (-) • ➢ % = 100 V/H V = Change in Elevation H = Horizontal Distance in Feet

  44. Vertical Highway Curve • Parabolic Curves ➢ Sag or Crest

  45. Vertical Highway Curve • PVC - Point of Vertical Curve • PVI - Point of Vertical Intersection • PVT - Point of Vertical Tangent • Length = PVT - PVC

  46. Highway Plan – Profile Sheet • ➢ Provides Two Dimensional View
