Tennesseans 12+: Now Eligible for a COVID-19 Vaccine


CADD Support


James K. Polk Bldg.
505 Deaderick Street
Suite 1200
Nashville, TN 37243

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 or phone, it is our duty to assist the following groups with specific problems they may be encountering in getting something done on their roadway projects.

  • Headquarters - Since our office resides at headquarters, this where most of our one on one or face to face support is provided.
  • Regional and Survey Offices - This help is usually conducted via email or by phone but occasionally does involve going to these remote locations for face to face assistance.
  • Other TDOT Divisions - Most TDOT Divisions do not have personnel directly assigned for support of CADD. Since Design is ultimately the place where all groups come together on project data, many have adopted and use our standards. These include Planning, ROW, Utilities, Geotechnical and Construction. Coordination with Structures and Aeronautics on various CADD issues are executed but with only occasional support.
  • Consultants - This help is conducted via email or by phone with only an occasional visit by consultants to our office.
