Color Codes

The nationally recognized color code system for utility locating provides a universally accepted system for engineers, facility managers and construction workers to be able to understand the type of utility that may he hidden under the ground, in walls or behind concrete.

When working in a mark-out area proceed with caution. Flags and paint markings are placed with the use of sophisticated utility locating equipment. Utility Survey uses advanced Ground Penetrating Radar, Radio Frequency location equipment and other devices in an effort to determine the type and depth of hidden obstacles.

Although markings are placed based upon the best understanding of the equipment output inaccuracies can occur due to equipment limitations and other factors. Do not make assumptions about the continuation of a mark out beyond the bounds of the survey area.
