A few years ago, the department's dis- of visualization technology use is based on the project trict value engineering coordinators discussed adding another manager's experience with the technology and discussion feature to the program, "value added." This concept caused with various in-house staff, vendors, and consultants. There some initial confusion as to whether to report the additions is no regional visualization division.

Value Engineering and Visualization Why the Need for Visualization? A value engineering study using visualization technologies was implemented and reviewed for Okeechobee Road (U.S. District 6 typically has several high-profile projects being Highway 27), a six-lane, controlled-access highway.
