Utility Surveying

Underground Utility Surveys

Subscan UDS complete full PAS 128 Utility Survey for designers and contractors.  Producing detailed guides so everyone working on a project understands exactly what they are dealing with when preparing and working on a site. Our underground utility surveys allow workers to establish exactly what buried obstacles they may face before breaking ground.  Preparing them for what they may come across, minimising costly delays from unknown obstacles.

It’s a legal requirement that before digging you should be aware of what is beneath the surface, ensuring there are no hidden surprises when you break ground. A hit gas main can not only be costly in terms of time and money, it can cause injury or worse. Subscan UDS use the latest detection techniques including Electromagnetic Detection, signal induced threading and Ground Penetrating Radar to locate utilities.

Ground Penetrating Radar (GPR) is a form of non-intrusive utility detection and can be used in a variety of materials including; rock, soil, ice, water and pavements.

PAS 128 Utility Mapping

Precise Utility Location: Using GPR technology, we accurately locate and map underground utilities such as water pipes, gas lines, electrical cables, and more.

Mapping and Documentation: We provide detailed reports and maps that outline the exact positions and depths of underground utilities.  Ensuring safety during construction, excavation, or renovation projects.

Safety and Risk Mitigation: Accurate mapping of underground utilities helps prevent accidental damage, costly repairs, and disruptions during construction and excavation activities.

Project Efficiency: Our data empowers architects, engineers, and project managers to make informed decisions, reducing risks and optimizing project efficiency.

Specialist detection & mapping

At Subscan, our commitment to excellence is reflected in our specialist detection and mapping services, where our skilled surveyors employ a range of cutting-edge techniques to ensure the highest standard of utility mapping. Our comprehensive approach includes electromagnetic location methods, ground-penetrating radar, and meticulous visual inspections.

The foundation of our service lies in delivering accurate and detailed information, empowering you to make informed and safe decisions on-site. Our surveyors utilize advanced technologies to create layered CAD models, providing a comprehensive representation of underground utilities. These models are complemented by detailed reports, ensuring that you have all the essential data at your fingertips.

Ground Penetrating Radar and
Electromagnetic Locating Technology

Subscan UDS utilise the very latest Ground Penetrating Radar technology and post processing software. From cutting edge ‘stepped-frequency continuous wave radar’ to high frequency 3D scanners.

New, innovative & powerful ‘Best In Class’ multi frequency electromagnetic locators are used on all Utility Mapping operations; giving the most accurate on site utilities information available and also highlighting potential locating issues such as ‘signal distortion’.

Emergency Work

In case of a utilities emergency, and you require to undertake excavation works at extremely short notice.  Subscan have a dedicated ad hoc team who can be on site within 48 hours (location dependant) to locate and mark out underground utilities.
