What is Utility Detection?

Utility Detection is the process of Locating and identifying buried pipes, cables and ducting usually belonging to utility companies providing electricity, gas, water, communications, sewers and drainage.

What is Utility Mapping?

Utility Mapping is the process of accurately surveying and plotting the location and depth of detected utilities.

Why use Utility Detection and Mapping?

Records maintained for main pipe and cables by Utility Companies are often incomplete and inaccurate. The Utility Companies stipulate that it is the responsibility of the organisations carrying out excavation work to accurately Locate the 3D position of the individual utilities before starting work.

The location of the connections from the mains to service individual properties are not recorded by the Utility Companies.

The Issues Related to Utility Detection and Locating.

Many Utility pipes/ducts are plastic, and storm water and sewer pipes are generally made from concrete, earthernware or plastic. These non metallic services cannot be readily detected by Electromagnetic "wand" type locators unless they have a trace wire attached.

Optical fibres also cannot be detected by Electromagnetic "wand" type locators.

The type of pavement/soil, depth of cover, height of water table and type of cable/pipe all have a significant effect on the performance of the Locating Equipment.

Significant OHS and cost implications can arise if undetected Utility Services are damaged during excavation works including:

• Death or Serious Injury to Construction Personnel
• Disruption to dependant businesses and homes
• Disruption and Delays to the Construction works
• Compensation Claims from the Utility Authorities
