Professional excavators are the last line of defense in protecting underground utility lines.
As an excavator or contractor, you play an important role in our efforts to keep citizens safe. If you are excavating a new building, repairing buried infrastructure, landscaping, residential paving, building concrete slabs, or anything else that requires you to break ground, you must contact Missouri 811.
Contacting Missouri 811 will help protect your project from unnecessary damages, injuries and financial penalties. We notify buried infrastructure owners that you are excavating. Once notified, they will then let you know where cables, pipes and wires are buried.
Be safe. Know what’s below.
The Process
Notify Missouri 811
Request a utility locate online or by phone at 811 at least three full working days prior to excavation.
Utilities Are Notified
Missouri 811 will notify any public utility companies within your dig site while you wait the required time.
Utilities Mark Their Lines
The utilities will locate and mark their lines, or provide an all clear notification.
Confirm the Marks
You confirm the marks and utility statuses.
Dig with Care!
Do you know what's below?
Utility color codes are used to identify existing underground utilities in construction areas with the intent of protecting them from damage during excavation. This is done with either flags or a special spray paint, neither of which will cause long-term harm to your lawn.
The American Public Works Association (APWA) Uniform Color Codes for temporary marking of underground utilities are listed below:
White
Proposed Excavation
Pink
Temporary Survey Markings
Red
Electric Power Lines, Cables, Conduit and Lightning Cables
Orange
Communication, Alarm or Signal Lines, Cables or Conduit
Yellow
Gas, Oil, Steam, Petroleum or Gaseous Materials
Green
Sewers and Drain Lines
Blue
Potable Water
Purple
Reclaimed Water, Irrigation and Slurry Lines
Advance Ticketing
The Advanced Ticketing tool allows schedulers to plan out projects during the planning process, often months in advance of breaking ground. When utilizing the Advanced Ticketing tool, users can place locate requests in a ‘tentative’ status and will receive an automatic email notification 7 days in advance of the project start date that was entered in the ITIC system. When the notification is received, the user will be prompted to either submit the locate request, edit the request, or delete it altogether. From here, the scheduler can proceed with finalizing the locate as their excavation plans dictate.
Ticket Types
Routine Ticket
This is a regular locate request. Utilities must respond by the start date/time listed on the locate request.
Emergency Ticket
Only to be requested when the situation meets the legal definition of an emergency. Utilities must respond in 2 hours.
Dig Up Ticket
Excavator legally required to notify Missouri 811 when damage to facilities has occurred. If damage involves pipeline or natural gas facilities, both 911 and the affected utility must be notified.
No Response Ticket
To be requested when one or more utilities fail to respond to the original locate request. If notification is made before 2 pm, the marking shall be completed that working day. If the notification is made after 2 pm, the marking is to be completed no later than 10 am the next working day.
Renewal Ticket
Submit a renewal when previously placed utility marks are no longer visible due to weather, construction activity, or when excavation has not been completed within the 21 consecutive calendar day Ticket Life.
Incorrect Locate Ticket
Ticket type to be requested when markings at the dig site are mismarked, out of the area described, at the wrong address or when statused incorrectly.
Design Tickets
Knowing what utilities are involved in the planning states of a project is an important aspect of damage prevention. Individuals involved in planning a project should use one of the two types of “Design” tickets available. Excavation cannot take place on either type of design ticket. A routine locate request must be placed before beginning work.
Preliminary Design Ticket
To be requested to determine what facilities are present when planning a project. Contact names and phone numbers will be immediately supplied. No markings will be made.
Design Ticket
To be requested when planning a project. Will generate actual markings at the site. Excavation cannot take place on a design ticket. A routine locate request must be placed before beginning work. Utilities are allowed 5 working days to respond.
