Utility Survey

What is a Utility Survey?

A utility survey is a detailed examination of underground utilities, such as pipes, cables, and ducts, to accurately map their locations and depths. This type of survey is essential for construction planning, excavation work, and infrastructure development, ensuring that all underground services are identified and avoided to prevent costly damage or delays. At Brookes Geospatial, we offer expert utility surveying services across Lancashire, West Yorkshire, and the UK.

How is a Utility Survey Conducted?

Utility surveys are conducted using advanced Ground Penetrating Radar (GPR) and electromagnetic equipment. GPR uses radar pulses to image the subsurface, detecting various underground utilities by identifying changes in material composition. Electromagnetic locators are then used to detect and map the positions of metallic utilities by responding to the electromagnetic fields generated by these utilities. Our team of skilled surveyors combines these methods to provide a comprehensive map of underground services, ensuring accuracy and reliability in even the most challenging environments.

How Can I View a Utility Survey?

We provide utility survey results in various formats to suit your needs:

  • PDF Copies: Ideal for easy viewing and sharing.

  • DWG Files: Used for further design and analysis in CAD software like AutoCAD.

  • Paper Copies: Available upon request, perfect for on-site reference.

Our deliverables are clear and user-friendly, ensuring that you can effectively utilize the survey data for your project.

What Are the Limitations of Utility Surveys?

While utility surveys provide invaluable information, there are some limitations to consider. GPR and electromagnetic methods may struggle to detect non-metallic utilities or those buried at great depths. Additionally, highly congested areas with multiple overlapping utilities can sometimes produce complex data that requires expert interpretation. Weather conditions and ground composition can also affect the accuracy of the survey. Despite these challenges, our experienced team at Brookes Geospatial is equipped to handle these limitations, providing the most accurate results possible.

Utility Survey Specifications: PAS128 Compliance

At Brookes Geospatial, we conduct our utility surveys in accordance with PAS128 standards, the recognized specification for underground utility detection, verification, and location. PAS128 outlines several quality levels, or "bands," that indicate the accuracy and reliability of the survey:

  • QL-D: Basic desktop utility records search.

  • QL-C: Site reconnaissance and survey of visible utilities.

  • QL-B: Detection of utilities using non-invasive techniques like GPR and electromagnetic locators.

  • QL-A: Verification of utility positions through physical exposure, providing the highest level of accuracy.

By adhering to PAS128, we ensure our utility surveys meet industry standards for accuracy and quality, giving you confidence in the data we provide.

How Much Do Utility Surveys Cost?

The cost of a utility survey can vary based on several factors, including location, complexity, and site conditions. For example, conducting a utility survey in a school playground during holidays is typically more straightforward and cost-effective than surveying a busy main road in Leeds or Manchester, which might require traffic management. Each project is unique, and we provide customized quotes based on your specific requirements.
