The Georgia Department of Transportation (GDOT) was preparing to relocate water and sewer mains coming from a rest area and paralleling I-75.
GDOT suspected that there were conflicts between newly proposed utility services and the existing utility lines in the right-of-way, and they hired a SUE consultant to provide utility information for the project.
A QL-B study and a subsequent QL-A investigation (excavation of test holes) revealed, however, that no conflict existed at the critical sections.
The utilities were not relocated, resulting in a savings of thousands of dollars.
