Overview

Electronic Engineering Data (EED) is typically produced during the design phase of a civil project and usually consists of various types of electronic design information that can be displayed graphically in a computer aided design file (CAD). Examples of EED include but are not limited to: 3D terrain models, coordinate geometry files and MicroStation CAD files.

Why is EED Needed from Designers?

In the past, contractors were not provided with EED at advertising; in order to use the newer technologies, the contractors would have to generate (reverse engineer) the required EED from the paper copies of the final design contract PDF plans. This process could be timely, costly and prone to error. State DOTs have begun requiring that accurate and reliable EEDs be developed in the beginning stages of a project and be delivered at final design. Nationally, the civil industry is quickly recognizing business improvements and lower costs by changing field operations to incorporate the use of these techniques.

What are the Benefits of Creating a 3D Model as a Designer?

  • To be able to see the whole model as one (communicates design intent)
  • To ensure all parts tie together (clash detection)
  • Valuable tool to represent data to others
  • Validates constructability of staging/final product
  • Better understanding of staging plans

How is EED Used During Construction?

  • Automated machine guidance (AMG)
  • Automated stakeout and inspection
  • Intelligent compaction
  • Generation of "live" as-builts
