Post-811 Verification
When you need more certainty after 811 markings are complete, Beyond 811 Locating provides an added verification layer to help reduce risk before digging starts.
Why post-811 verification matters
811 is essential, but jobsite conditions, private utilities, unclear markings, and high-risk excavation scenarios may still require another layer of underground clarity. Post-811 verification helps close that confidence gap before work moves forward.
This service is especially valuable when the project carries real schedule pressure, underground uncertainty, or a low tolerance for strikes and delays.

Post-811 Verification FAQs
Is 811 still required?
Yes. 811 remains the required first step before most excavation. Post-811 verification is the added layer when more underground certainty is needed.
When should I request verification after 811?
When markings are unclear, private utilities may be present, the site is complex, or the project risk is high enough that you want more confidence before digging begins.
Who uses post-811 verification?
Contractors, commercial site teams, developers, and property owners who need more reliable underground understanding than a basic locate ticket alone may provide.
