Our Underground Utility Locating Capabilities

Our utility locating services can help you determine the location and depth of underground utilities before you dig, drill, or design a new project.

Why Our Utility Locating Services Are Needed

Prior to digging or drilling on public or private property the responsible person must call 811, a national organization that is responsible for the damage prevention of publicly owned underground utilities. Upon receiving this call, a notification message is sent out to all utility companies and municipalities that own services in the town work is going to be performed in. As soon as this message is received, technicians are mobilized to the site within at least 48 hours to mark the location of underground utilities running near or through the work area. Once these lines have been marked out, digging or drilling can legally begin. 

Since its inception, this program has been a huge success. It has reduced the risk of personal injury and saved utility companies, municipalities, and property owners countless millions of dollars in utility repair costs. Despite the program's many successes, however, it suffers from the following limitations:
811 Call Before You Dig
  • Not all utility companies and municipalities participate in the program
  • Only underground utilities documented on asbuilts will be marked out
  • The high volume of daily locates often causes mistakes to be made
  • Non-metallic, abandoned, and unknown lines cannot be located
  • The depth of underground utilities is not provided
  • The technicians have no direct contact with the excavator or driller
  • Non-conductive utilities are marked using asbuilts, which are often outdated and inaccurate
  • Each utility type is marked by a different company, making it impossible for their techs to obtain a holistic view of the site
  • Privately owned utilities--which constitute 65% of all underground utilities in the United States--are not marked at all
Our utility locating services can help combat the aforementioned limitations and, most importantly of all, provide drillers, excavators, and property owners with the location and depth of privately owned underground utilities outside the jurisdiction of the public 811 system.


Our Six Utility Locating Survey Design Options

In order to handle a wide variety of different types of projects, we offer our clients six different survey design options. Feel free to choose the option that best fits your needs. If you are not sure which one that is, we can recommend one for you after learning more about your project.

Single Line
Single Line Underground Utility Mark Out

When a single underground utility line needs to be located, which is often the case for residential and small commercial projects, we can limit our mark out to only this one line.

Trench Line Clearance
Trench Line Underground Utility Clearance

When an electrical, telecommunication, water, gas, or sewer line is going to be installed, in order to save time and money we can confine our utility mark out to an area surrounding the proposed trench line.

Partial Property
Partial Property Underground Utility Mark Out

When excavation or drilling is going to be performed within one small section of a large property, or a new construction project is being designed there, in order to save time and money we can confine our utility mark out to this one area of the property.




Multiple Lines
Multiple Underground Utility Line Mark Out

When more than one underground utility line needs to be located, which is often the case for large residential and most commercial projects, we can expand our mark out to include each one of these lines.

Borehole Clearance

When drilling in one spot, such as for the installation of a new sign post, grounding rod, bollard, monitoring well, or soil boring, we can confine our utility mark out to a 20' x 20' area surrounding this one location.

Full Property

When a complete picture of the underground site infrastructure is needed, we can expand our utility mark out to include the entire property. This is the survey design of choice for land surveyors who are in the process of creating a civil survey map.
