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.
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:
Temporary Survey Markings
Electric Power Lines, Cables, Conduit and Lightning Cables
Communication, Alarm or Signal Lines, Cables or Conduit
Gas, Oil, Steam, Petroleum or Gaseous Materials
Sewers and Drain Lines
Reclaimed Water, Irrigation and Slurry Lines
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.
This is a regular locate request. Utilities must respond within 3 working days.
Only to be requested when the situation meets the legal definition of an emergency. Utilities must respond in 2 hours.
Dig Up Ticket
Excavators are legally required to only notify Missouri 811 when damage to facilities has occurred. If damage involves pipeline or natural gas facilities, both 911 and the affected utility must also 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.
To be used when previous marks are not visible and need to be remarked due to weather or construction. This is also required if excavation has not started within 10 business days. Utilities must respond within 3 working days.
Incorrect Locate Ticket
Ticket type to be requested when markings at the dig site are mismarked, out of the area described or at the wrong address. Utilities must respond within 2 hours.
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
The “Preliminary Design” ticket identifies all members within a given area. A list of contacts and phone numbers are made available to the requestor. No locate request is transmitted to member utilities. A routine locate request must be placed before beginning work.
The second type of Design ticket will generate an actual locate request allowing a (5) working day response time by the member utilities notified. A routine locate request must be placed before beginning work.
