At Sygma Solutions Ltd., we recognise that cable avoidance is an essential part of construction and excavation activities. Accurate detection of underground utilities prevents unnecessary damages, disruption of services, and, above all, potential risks to employees and the general public.

Even with the implementation of sophisticated machinery such as the Cat and Genny, cable avoidance remains a problem.

In this article, we discuss some of these issues and how they can be successfully overcome.

Operator Errors Due to Inadequate Training

Misuse of Cat and Genny equipment can result in missed or misread cables, making damage more likely.

Solution:

  • Provide operators with extensive training, as the courses offered by Sygma Solutions Ltd. do.
  • Hold regular refresher courses to maintain skills at their best and current.

Outdated/Inaccurate Utility Maps

One of the most prevalent problems operators encounter is using inaccurate or outdated utility maps. Such records might not indicate recent changes to infrastructure, raising the potential for utility strikes.

Solution:

  • Always cross-check maps with a site survey prior to excavation.
  • Utilise the most advanced technology, such as ground-penetrating radar (GPR) and electromagnetic detection equipment.
  • Cross-check maps with several data sources where possible.

Ground Conditions

Some types of soil, for example, wet or clay-based soil, will interfere with the reception of signals and decrease the efficiency of detection equipment.

Solution:

  • Adjust equipment settings for varying ground conditions.
  • Make multiple passes with various frequencies to enhance accuracy.
  • Use auxiliary tools such as signal clamps or sondes for better readings.

Interference from Adjacent Utilities

Superimposed signals from various utilities may render individual lines difficult to identify.

Solution:

  • Apply frequency filters and signal differentiation methods.
  • Employ systematic scanning patterns to demarcate overlapping signals.
  • Refer to experienced professionals for challenging detections.

Time Pressure Resulting in Hurried Surveys

In close project timelines, operators can be in a hurry to detect utilities, which will lead to errors.

Solution:

  • Provide enough time for proper surveys.
  • Promote a safety and accuracy culture over speed.
  • Utilise pre-dig meetings to emphasise the need for cautious cable avoidance.

Final Thoughts

Cable avoidance is crucial for safety and efficiency in excavation works. By overcoming these shared risks through effective training, the use of suitable equipment, and a systematic approach, operators can sufficiently minimise the threats of utility strikes.

At Sygma Solutions Ltd., we offer top-of-the-line training programs to equip experts with the capability and experience necessary for efficient cable avoidance.
