Before You Dig
Safe digging is everyone’s responsibility, but excavators have more responsibilities under the law and higher risk if the proper processes aren’t followed. Submitting a ticket is the first step but it’s not the only step, and sometimes it takes more than just the one call.
Steps to Safe Digging
PLAN YOUR PROJECT
SUBMIT A TICKET
Provide a 2 – 10 full working day notice, not counting day of notification, prior to the proposed start of excavation.
WAIT FOR MARKS
CHECK TICKET RESPONSES
CONFIRM THE MARKS
DIG WITH CARE
EXTEND THE LIFE OF THE LOCATE REQUEST

HELPFUL TIP:
The proposed areas of excavations can be marked with white paint in order to show the location or boundaries of the proposed excavation. This helps with the efficiency of the locate process.
What is a Positive Response?
Positive Response is a process to facilitate communication between utilities, excavators and Alabama 811, regarding the status of identifying and marking the underground facilities within the proposed area of excavation on locate request tickets.
Responses can be viewed in real-time via the Find Locate Request link on the Alabama 811 WebPortal.
- Visit https://geocall.al811.com/geocall/portal
- Select Find Locate Request, enter your locate request ticket number in the search box and click search.
- Your locate request ticket will be shown on the right side of the screen.
- Scroll to the bottom of the locate request ticket to view the actions posted for each participating member utility company.
Our member underground facility owners must provide positive response, or give the “all clear,” before you can begin digging. You can check the status of your request online HERE by clicking the “Find Locate Request” option. You will need your locate request number to access the system. If a facility has not responded, we suggest that you contact Alabama 811 to have a second notice sent to members to let them know it has not been marked so that they can get it marked for your safety and protection.
If you would like to submit responses for your company you will need to fill out a registration form HERE.
Positive Response option for HIGH VOLUME tickets – For members that receive a high volume of locate requests, use a ticket management system or use your own response system, you will want to register for the automated upload to the positive response servers. Please indicate your interest on the registration form. Alabama 811 will provide documentation outlining the setup needed to enter responses into the positive response system.
Positive Response for the Alabama 811 WebPortal and Mobile App – The Alabama 811 WebPortal and the Alabama 811 Mobile App are resources available to members to document and record their responses to the locate request notifications received. The excavators will have the ability to look up the ticket and view the responses from members on the locate requests. The responses submitted will inform the excavators if utilities have been marked, are clear of the excavation

Use of color-coded surface marks (paint, chalk, flags etc) is to indicate the location and route of buried facilities. All marks should indicate the name, initials or logo of the company that owns or operates the lines to help determine the proper facility owner if needed. If the width of the facility is greater than 2” (5mm) then it is good to indicate the width. If the surface above the buried facilities is to be removed, such as asphalt removal, then supplemental offset marks may be used. Offset markings should be on a uniform alignment and must clearly indicate the actual facility specific distance.
