Every day across Illinois, you build the communities we call home. That role comes with great responsibilities…like maintaining a productive and accident-free job site. Reduce the risk of striking an underground utility line and keep crew members safe by contacting JULIE before you dig. Respect the lines. Protect the lives.
The tolerance zone—a pre-defined horizontal distance extending from the outer edge of underground facility marks, to the depth of your proposed excavation—acts as a warning to proceed with caution while digging in this area.
REV makes it easy for you to REFRESH markings that have become indistinguishable, EXTEND an existing locate request, or VIEW a locate request from the past 6 months.
