  6. Preliminary Investigation • 30% Plans Are Sent To The Utility Companies • Rough Drainage • No MOT • Incomplete Grading • Utility Company Resource Issues • Many Projects Die Between P.I. and Final • Provide High “Ball Park” Estimates That Will Often “Kill” Project.

  7. Semi Final – PS&E • As SHA Plans Improve • Drainage Is Complete • Test Pitting Clarifies Impacts • Utility Estimates Are Updated • As Real Impacts Are Known, Estimates Become More Focused • Estimates Maintain High Contingencies Factor Because of “Risk”

  8. Prior Rights • SHA initiates the “RW57” Form Process • Utilities identify impacted facilities • Utilities research for existing easements and Rights of Ways • Submit to SHA for review • SHA reviews and validates research • Final percentage is: Total “Covered” Facilities/Total Facilities

  13. Results – Data Source • SHA’s Project Cost Database • 925 Total Projects Since 1992 • 773 Projects with Complete Data • 45 Projects with Cost Not Estimated • 107 Projects without Final Cost

  14. Results – Total Dollars Values In Millions

  15. Results – Total Cost Values In Millions

  16. Results – By Project

  17. Process Issues • Wide Variation on Individual Projects • Utility Estimates During Design Excessively High often Killing Projects • DOT Can’t Verify or Predict Utility Estimate • Utility Company can’t Respond to the Schedule or Flexible needs of DOT
