What We Do
Vannguard is a contract locating company
based in the Midwest.
We contract with utilities to locate and mark their buried facilities prior to excavation. These utilities can be large investor-owned, rural cooperatives, or city-run municipalities.
Facilities We Locate & Mark
Gas & Electric represent 97% of Vannguard’s locating business.
The One Call System
Starting in the 1980s, laws were passed requiring utilities to become members of a state One Call system. This system simplified the process for excavators — before it existed, they had to call each utility directly.
Multiple utilities may need to be identified at a single job site — each locator is only responsible for its own customer’s facilities. Someone else may show up to locate the others. The service is free to the excavator, supported by the utilities. When the One Call center, excavator, and locator work together, everyone digs safely and the community stays safe.
