Subsurface Utility Mapping(SUM)
Subsurface Utility Mapping(SUM)
Quick View
Who: Excavators, developers, utilities, contractors.
Why: One fiber optic strike cost a developer $92,000. Gas line strikes kill people. 811 call-before-you-dig only covers marked utilities—not private lines, abandoned cables, or mismarked infrastructure.
What You Get
- Underground utilities located and mapped
- Depth and location verified with EM and GPR
- Private and public lines identified
- Utility conflict reports for engineering
A contractor in Gwinnett County relied on 811 markings. Hit an unmarked fiber trunk on day two of excavation. Repair cost: $67,000. The entire neighborhood lost the internet for 18 hours. The carrier sued.
Another developer struck a gas line not shown on any utility map. Site evacuated. The project shut down for three days while the gas company made repairs. Delay costs plus fines: $41,000.
811 doesn’t mark everything.
Private lines, old cables, and mismarked utilities put your crew and your budget at risk.
