The Essential Guide to Utility Survey Mapping

Posted by John MacIntyre

Technics has been at the forefront of providing effective subsurface utility surveys, earning a solid reputation for delivering comprehensive solutions across various sectors. Our expertise in underground utility mapping ensures clients receive accurate, detailed, and reliable results tailored to their project needs.

The Value of Underground Utility Mapping

Underground utility mapping is essential for creating an accurate plan of the subsurface environment. Utilising advanced technology, we provide a clear and comprehensive view of the assets beneath the surface. Our Vacuum Excavation service further enhances our capabilities by safely exposing utilities to fulfil the PAS 128:2022 specification quality level QLA.

The Benefits of Underground Utility Survey Mapping

Conducting an underground utility survey offers numerous advantages, especially before breaking ground. Here are some key benefits:

  • Reduced project planning time: Streamline your project timeline by clearly understanding subsurface utilities.
  • Minimised risk: Reduce the chances of unforeseen issues during excavation.
  • Health and safety compliance: Ensure adherence to health and safety regulations, safeguarding your team and the public.
  • Confidence in excavation: Gain assurance in identifying ‘safe’ areas for excavation or the safest route for proposed utilities.
  • PAS 128:2022 compliance: Meet industry standards, avoid surprises and make better-informed decisions.

The Consequences of Not Using Utility Mapping Survey Data

Not obtaining accurate utility mapping data when commissioning, planning, managing, and carrying out works on or near underground services poses a significant risk.

  • Injury or fatalities – striking underground utilities, such as electrical cables, gas pipelines, or water mains, can result in serious injuries or fatalities to workers and bystanders.
  • Fire and explosions – damaging gas pipes can lead to leaks that may cause fires or explosions.
  • Utility outages – Damaging water, gas, or electrical lines can disrupt services for many people, potentially impacting residential, commercial, and industrial operations. Cutting through telecommunication lines can lead to disruptions in phone and internet services, affecting businesses and emergency services.
  • Project delays – Repairing damaged utilities can cause significant delays to the construction project, leading to increased labour and equipment costs.
  • Contamination: Damaging sewer or chemical pipelines can lead to environmental contamination, affecting soil and water quality. Leaks from damaged pipelines can harm local wildlife and disrupt ecosystems.

To mitigate these risks, it is crucial to conduct thorough utility surveys using methods such as ground penetrating radar, and electromagnetic location devices, and procuring utility reports before commencing any excavation work.

Understanding PAS 128:2022

The PAS 128:2022 specification provides comprehensive guidelines for underground utility detection, verification, and location. It includes updates on training and qualifications for practitioners, post-processing in detecting surveys, and controls for the accuracy of detection methods. This standard sets a benchmark for all practitioners, ensuring high-quality and reliable survey data for clients.
