Cost Estimation System CES Implementation at NDOR TUG 2006

NEBRASKA

Diverse Roadways

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

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

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 pricesNeeds

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 Trnsport system maintains the integrity of the estimate prices allows for snapshot capability at any point in the life cycle Why CES

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 estimateWorkflow

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 Who ya gonna call…

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

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 Basic Training
