Contractor Toolbox

Take the key concepts that you learned in the 811 Pro training back to your organization with our downloadable educational assets.


Pre-marking your job site is the first step in the 811 process. It’s simply outlining the boundaries of your project with white paint, flags, or stakes so that the responding utility companies can clearly see your work area and mark their lines.

On average, we notify 8 different utility companies for each 811 ticket and keeping track of those responses can be tough. Electronic Positive Response makes it easy by collecting our utility company's responses in one place. Grab your ticket number and click the link below to check your ticket status.
