  1. The Costs & Benefits of Implementing a MLLRS Sponsored by the AASHTO and FHWA and Conducted in the NCHRP

  2. Value Engineering • The value engineering study that was conducted for the NCHRP to support the NCHRP Project 20-07, Task 302. • The task was requested from the American Association of State Transportation Officials (AASHTO) • The report was conducted to identify the costs and benefits of implementing and maintaining a statewide Multi-Level Linear Referencing System (MLLRS)

  3. Value Engineering • The VE study was conducted at the Iowa Department of Transportation with a study team consisting of: • Renee L. Hoekstra, CVS, RH & Associates • Jerome Breyer, Works Consulting • Jun Wu, North Carolina Department of Transportation • Michael Sheffer, Maryland State Highway Administration • Thomas Martin, Minnesota Department of Transportation • Peggi Knight, Iowa Department of Transportation • Eric Abrams, Iowa Department of Transportation • Karen Carroll, Iowa Department of Transportation • Ryan Willie, Iowa Department of Transportation • Bruce Aquila, Intergraph • Gary Waters, ESRI

  4. What is a MLLRS? • Meets the NCHRP 20-27(2) data model • Includes multiple linear referencing methods, multiple cartographic representations and multiple network representations • Associates with a central object referred to as a “linear datum” • Meets the needs of integrating increasing amounts of linearly referenced data • Logically linked with other organizational electronic management systems

  5. Benefits of a MLLRS in a State Agency • Quantitative Benefits • Identified as time and cost savings by reducing: • Staff hours • Operational hours • Hours within other departments • Improved stewardship of data • Business/Operational unit improvements

  6. Quantitative Benefits • Business/Operational Unit Improvements • Sample Business/Operational Units Used • Safety improvements • Reduced level of risk for litigation • Reduced impacts to projects • Reduced maintenance • Baseline Savings • $1.1 million • Optional Functional Elements Savings • $2.5 million

  7. Qualitative Benefits • Ease of use and accessibility • Flexibility and integration • Quality of data • Internal and external collaboration • Data-driven decision support

  8. Other Identified Benefits • Facilitates the Breakdown of Departmental Silos • Able to Take Advantage of External Resources • Increased Opportunity to Integrate MLLRS into the Field Operations

  9. Costs to Implement a MLLRS • Capital Costs • Baseline - $2 million • Optional Functional Elements • Manage Change - $31,650 • Model Connectivity - $795,000 • LRM Development - $40,000 each

  10. Costs to Implement a MLLRS • Maintenance Costs • Baseline - $252,000 • Optional Functional Elements • Minor adjustments only

  11. Cost/Benefit Analysis • Based on a 5-year period • 3% escalation rate, constant dollar approach • Baseline - $2.5 million in savings • Cost/Benefit Ratio – 2:1 • Optional Functional Elements - $10 million in savings • Cost/Benefit Ratio – 21:1
