  3. Background • 17 Years of Experience with Utilities • Majority of KCI’s Work is Directly for the Utilities. • Understanding of DOT’s Needs and Schedules. • Success with Utility Coordination Comes From Successful Relationships.

  4. Maryland’s Process • Project Planning • Utility Estimates by Highway Planners. • Rough Assessment Approach. • 2002: SHA asked KCI to Develop “Planning Level Utility Estimating Matrix”.

  5. Planning Estimate

  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

  9. Prior Rights • Grey Areas • Pole Outside of Right of Way, Conduit in Right of Way • Cables Feeding from County Road

  10. Risk Management • DOT’s Risk • Under Estimate Funding Request • Higher Bids Due to Unknown Utility Involvement • Delay Claims Due to Concurrent Utility Work • Higher Bids Due to Construction Methods • Overhead Clearances • Handwork

  11. Risk Management • Utility Company’s Risk • Under Estimate Project Funding • Loss of Service to Customers • Increased Effort for Relocation

  12. Maryland’s Process Utility Estimate By Highway Planner Estimate By Utility with 30% of Information Planning Estimate Impacted Utilities Known, Estimates With Contingences and Prior Rights Complete Final / PS&E Estimate Actual Construction Rubber Meets the Road

  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

  18. New Approaches • Consultant Involvement with Utility Review • Relieves burden on Utility Companies • Works to DOT’s Schedule • Develop Utility Cost Data • Interactive Coordination During Design • Reduce Changes • Continue to Develop Relationship with Utilities.
