It is our utmost pleasure to promote respective personnel/software users in the development of roadway projects using Computer-Aided Drafting and Design (CADD) in the most accurate and efficient manner available thereby making the best possible use of time and resources.

Our goal is to support designers in accomplishing roadway projects in a timely manner so regardless of what other CADD support effort we may be working on at the time, our software users and their projects always come first!

Either face to face or via email, phone or Teams, it is our duty to assist TDOT personnel and consultants with problems they may be encountering.
