Why Are Underground Utility Surveys Necessary?

When it comes to locating utilities, you need to conduct underground surveys for a number of reasons. For starters you can use the survey to pinpoint the location of the utilities, and identify ant leakages that might need to be addressed immediately. It is important to identify the location of existing pipes if you intend to install new piping. Workers, surroundings and neighboring residents are all at risk if the existing utilities, such as gas pipes, are damaged during excavation work. A professional service provider needs to conduct underground surveys to safeguard the workers, and public at large.

Underground Utility Survey Techniques:

Buried utilities, such as conduits, piping and cabling, can be located using a number of techniques. Each of these techniques has their own associated advantages and disadvantages. https://precision-um.ie chooses the most appropriate technique after taking a variety of factors into consideration, including the lay of the land area. The use of radio or electromagnetic waves and ground penetrating radar are the main techniques considered. 

When Choosing The Right Technique The Following Factors Are Considered

Soil conditions, type of survey being carried out, the type of land on which the survey is being carried out, how deep the utilities are buried and topography of the land under consideration are some of the main factors that influence surveys. In some cases, for Precision Utility Mapping Ireland to get the most accurate and precise report on buried utilities, the radio wave technique might have to be used if the electromagnetic alternative is unable to generate accurate results.

During Surveys, The Following Health And Safety Issues Are Considered

Engineers must keep a number of important aspects in mind when performing underground utility surveys:

  • Limiting the survey work to a specific portion of land
  • Making sure that gas piping is detected
  • Traffic within the affected area

Engineers Can Conduct The Following Levels Of Underground Surveys:

•              Level One: Looking for the results in company records.

•              Level Two: Identifying underground utilities using an electromagnetic locator.

•              Level Three: Using CAD (Computer Aided Design) to map out the area covered under level two.

•              Level Four: Pit covers and manholes are lifted in while carrying out a level three survey. CAD is used to map out all the findings.

•              Level Five: Radar technology is used to define the area covered under level four.

•              Level Six: Radar technology is used to survey the area covered by both level one and level five surveys.


The term underground survey refers to field inspections that are meant to identify the location of buried utilities.

The main reason for conducting these surveys is to pinpoint the location of buried utilities.

The most commonly used techniques are Ground Penetrating Radar and Electromagnetic Locators.  

The specific technique to be used is dependent on a number of factors.

When conducting underground surveys, health and safety regulations must be considered.

Underground surveys are categorized into six different levels.
