  1. Best Practices and Benefits of Estimating Techniques and Technology Cindy L. Menches, Ph.D., P.E. Stephen M. Kleps, P.E. Illinois Institute of Technology

  2. What’s in the best practice guide • Review of estimating methods: Manual, on-screen, CAD-based • The current estimating landscape (i.e., who’s doing what) • Migrating to CAD-based estimating: Benefits and challenges • Obstacles to adopting CAD-based estimating methods • Best practices (…of all three estimating methods) • Case studies: Manual, on-screen, CAD-based estimating

  3. The estimating landscape

  4. Subjectively experienced Benefits For PDF and CAD-Based estimating software: • Potential time savings…but will vary with the method • Potential for greater accuracy…and organization • Younger estimators are comfortable with technology • Great presentation value for clients • It’s an extra “tool” in the estimating “toolbox”

  5. Obstacles to Technology adoption For PDF and CAD-Based Estimating Software: • Cost for hardware, software, and training • Skepticism about the magnitude of benefits • Concerns about obsolescence • Misconceptions about integration with existing system

  6. Obstacles to Technology adoption • Difficulty in obtaining native CAD files • Incompatible CAD files • The estimator must know CAD For CAD-Based Estimating Software:

  7. Best Practices Just a few…for more, review the guide • Vary the method to optimize time versus accuracy • Estimators are more satisfied (and perform better) when they can choose their own method • Beginwith one or two licenses

  8. Best Practices • Clean up CAD files first to maximize efficiency • Utilize the automatic quantity updating feature • Venture into PDF or CAD-based estimating to add more tools for estimators to use
