Implementing the Cost Estimation System (CES) for Effective Project Management in NDOR, Nebraska

In 2006, Nebraska's Department of Roads (NDOR) implemented the Cost Estimation System (CES) to manage a state highway program valued at approximately $350 million. The CES enhances estimation efficiency by utilizing multiple bid histories, allowing for long-range and item-level estimates. It addresses price instabilities and incorporates inflation into decision-making processes, ensuring accurate project pricing. The implementation included extensive training for estimators to optimize system use, enhancing project scheduling and management capabilities across over 250 annual contracts.

  1. Cost Estimation System CES Implementation at NDOR TUG 2006

  2. NEBRASKA

  3. Diverse Roadways

  4. Background • Nebraska’s State Highway program is an estimated $350,000,000 • Nebraska’s Lettings consist of 250+ contracts per year • Nebraska has 400+ active contracts at any given time

  5. Background • Centralized Estimating section • 5 Estimators • 50 + years of experience • Bid Based Estimates • Currently using PES generate bid based prices • Only able to use one bid history

  6. Needs • NDOR is having to adjust schedule of program due to price instabilities • Management wanted to factor inflation at the project level into decision making process • Use inflation to get a better idea of total project price as you move projects in the schedule • Open up possibility to use cost sheets to validate prices

  7. Why CES • CES is a tool for the complete life cycle of the estimation of a project • Ability to use multiple Bid Histories and group items based on type of Contract • Allows the estimator to work more efficiently • Integral component of Trns•port system • maintains the integrity of the estimate prices • allows for snapshot capability at any point in the life cycle

  8. Trns•port Modules Estimation Projects & Proposals Bid Lettings Construction BAMS/DSS Data Warehouse CES PES LAS SiteManager SiteManager Materials Expedite

  9. Workflow Project begins in CES • Long Range estimates - project-level estimates based on project work types and their major cost groups • Item-level estimates - bid item estimates derived from bid histories • Export to PES • Snapshots taken to track evolution of the estimate

  10. Who ya gonna call… • Called Info Tech • Kathy Yelle and troops • Developed Contract Agreement • 1.75 service units • Pre-work on developing bid histories • 3 days on-site implementation and discussion • 3 days on-site training and discussion

  11. Market Areas - DSS • Market areas help define your price indexes • Same types of items - Same types of jobs • Market Types (redefined in 2004) • Asphalt • Concrete • Structures • Districts

  12. Market Areas - DSS • Project begins in CES • Long Range estimates - project-level estimates based on project work types and their major cost groups • Item-level estimates - bid item estimates derived from bid histories • Export to PES • Snapshots taken to track evolution of the estimate

  14. Market Areas - DSS • Project begins in CES • Long Range estimates - project-level estimates based on project work types and their major cost groups • Item-level estimates - bid item estimates derived from bid histories • Export to PES • Snapshots taken to track evolution of the estimate

  15. Market Areas - DSS

  16. Bid Histories - DSS • Using HIREG to develop based on Market area and Time - Input • Time - 3 year, 2 year, 18 months, 1 year • Determined type of observations to include - Input • low bid, low 3 bids, all bids • minimum of occurrences • Bid Histories -Output • Weighted Averages • Regressions

  17. Basic Training • Two Days User • High level - Navigation, Shortcuts, best practices • More detailed level – Utilizing multiple libraries, standard task, snapshots • One Day System Administrator • High level - Navigation, User Roles • More detailed level – Creating and maintaining libraries

  18. Basic Training

  19. Basic Training

  20. Retirement…???

  21. To Do • CES to PES Export • Working with TTF, Info Tech and other Agencies • Customize Screens • Create Reports • Detail estimate report with inflation
