Underground Utility Survey Services


Comprehensive Underground Utility Survey Services

At Cambridge Measured Survey, we specialise in capturing intricate underground data that is crucial for any construction or renovation project. Underground surveys form an essential part of ground investigations, helping to identify potential obstacles and safe zones before beginning any invasive works onsite. Our team employs advanced tools such as Ground Penetrating Radar (GPR) and Electro-Magnetic Locators (EML) to meticulously capture and analyse underground data. Benefit from our extensive range of services, including concrete and rebar scanning, drain surveys, and CCTV surveys using robotic cameras, all designed to facilitate precise planning and flawless execution of construction projects. Trust our measured surveyors to provide reliable underground survey services alongside top-tier GPR services and CCTV drain survey services.

What is an Underground Utility Survey?

An underground utility survey is a critical process that uses various technologies to detect and map the location of hidden services and infrastructure. This type of survey is essential for any project that requires digging or excavation, as it ensures that all underground utilities are identified and accounted for, minimising the risk of damage and enhancing safety on the project site.

What Can an Underground Survey Detect?

Our utility surveys are designed to locate all major underground utilities, including sewers, electricity and gas mains, water pipes, fibre optic lines, lighting cables, communication networks, and traffic signalling cables. These comprehensive surveys provide vital information on underground conditions, ensuring that site excavations, drilling, piling, or borehole operations are conducted safely and efficiently. By determining the location of underground utilities early in the project, we help ensure smooth operations throughout the design and build stages, avoiding costly delays and accidents.

Underground Utility Surveying Methods

  • Radio Frequency Location (RFL) Technology
    This technology utilises radio waves to detect and locate metallic and non-metallic underground utilities, such as water and gas pipes, helping to prevent service interruptions and accidents during excavation.
  • Ground Penetrating Radar (GPR) Technology
    This method employs radar pulses to image the subsurface, ideal for mapping hidden objects and changes in material properties. GPR is crucial for detecting non-conductive materials including PVC pipes and fibre optics.
  • CCTV Drainage Surveys
    We use advanced robotic cameras to inspect sewer lines and drainage pipes, ensuring they are free from blockages or damages prior to any construction activities.
  • PAS 128 Utility Survey
    Adheres to the PAS 128 standard, providing a strategic framework for the detection, verification, and location of active, abandoned, redundant or unknown utilities.
  • Concrete and Rebar Scanning
    Essential for structural renovations or upgrades, this technology detects embedded rebar, conduits, and post-tension cables within concrete structures, ensuring structural integrity.

FAQ About Underground Utility Survey

A utility survey is a specialised process that identifies, locates, and maps underground utilities and services. Using advanced detection technologies, these surveys help prevent damage to underground infrastructure during construction activities and ensure safety on the site.

Underground utility surveys are crucial for identifying the position of hidden services such as gas, water, electricity, and telecommunications cables. These surveys help mitigate risks associated with accidentally damaging utilities during excavation, which can lead to costly repairs and safety hazards.

In a utility mapping survey, technologies like Ground Penetrating Radar (GPR), Electro-Magnetic Locators (EML), and Radio Frequency Location (RFL) are utilized to detect and map underground utilities accurately.

A PAS 128 utility survey follows the PAS 128 standard, providing guidelines for the accurate detection, verification, and depiction of underground utilities. This survey includes a detailed assessment of the location and type of underground assets, ensuring high-quality data for construction planning.

Underground utility surveys can detect a wide range of services, including but not limited to water and sewer lines, gas and oil pipelines, electrical power cables, communication cables, and fiber optic lines.

Using GPR in underground surveys and utility mapping allows for the non-invasive detection of non-metallic and metallic utilities. GPR is highly effective in providing a clear picture of what lies beneath the surface, which is essential for planning any excavation or construction work.

Sewer maps created from utility surveys are highly accurate, reflecting the precise location and depth of sewer systems. These maps are invaluable for municipal planning, maintenance, and ensuring that new construction does not interfere with existing sewer infrastructure.
