Underground Utility Mapping

Subvision Surveys Ltd, with 25 years of industry experience, uses the latest electromagnetic and GPR equipment for accurate underground utility mapping. Our expertise extends to major projects like Heathrow T2, The Shard, Wembley Stadium, and the O2 Dome. Due to incomplete and inaccurate statutory utility records, high-quality surveys are essential for a safe working environment.

Why Use Underground Utility Mapping?

Underground utility mapping helps you avoid costly damages, improve safety, and ensure regulatory compliance by precisely locating buried infrastructure. Underground utility mapping optimises construction planning, reduces the over running of projects, and reduces the risks of service disruptions, ultimately saving time, resources and money.

Underground Utility Mapping – Purpose

The core objective of underground utility mapping is to stop damage to utilities during construction and excavation projects, improve safety, and support the planning and maintenance of urban infrastructure.

Underground Utility Mapping – Key Components

  1. Data Collection:
    • Geophysical Methods: Ground Penetrating Radar (GPR), Electromagnetic Induction (EMI), and sonar are used to detect and locate subsurface utilities without excavation.
    • Non-Geophysical Methods: Visual inspections, utility record searches, and site reconnaissance to gather information from existing documentation and visible utility markers.
  2. Data Processing:
    • The raw data gathered from surveys is processed and analysed to identify the exact locations and conditions of underground utilities.
    • Software is used to convert survey data into usable maps and models.
  3. Data Presentation:
    • The results are presented in the form of detailed maps, 3D models, and reports.
    • Geographic Information Systems (GIS) are often used to integrate and visualise the data.

Underground Utility Mapping – Techniques and Technologies

  1. Ground Penetrating Radar (GPR):
    • Sends radar pulses into the ground and detects reflected signals from buried objects.
    • Effective for detecting non-metallic utilities like plastic pipes.
  2. Electromagnetic Induction (EMI):
    • Uses electromagnetic fields to detect metallic utilities.
    • Can be affected by the presence of multiple utilities and other metal objects.
  3. Magnetic Locators:
    • Detect magnetic fields generated by ferrous metal objects like cast iron pipes.
    • Limited to detecting ferrous materials.
  4. Acoustic Methods:
    • Uses sound waves to detect and locate utilities.
    • Useful for detecting voids and non-metallic pipes.
  5. Vacuum Excavation:
    • A minimally invasive method to expose and verify utilities.
    • Provides the highest accuracy for utility location.

Underground Utility Mapping – Applications

  1. Construction and Excavation:
    • Ensures the safety of workers and the public by preventing accidental strikes on buried utilities.
    • Minimises project delays and costs associated with utility damage.
  2. Urban Planning and Development:
    • Helps in designing infrastructure projects by providing accurate subsurface utility information.
    • Supports the efficient use of space and resources in urban areas.
  3. Infrastructure Management:
    • Aids utility companies in maintaining and managing their underground assets.
    • Facilitates proactive maintenance and reduces the likelihood of service disruptions.
  4. Environmental Protection:
    • Prevents environmental damage caused by rupturing gas or chemical pipelines.

Underground Utility Mapping – Benefits

  • Safety: Reduces the risk of accidents and injuries during excavation.
  • Cost Efficiency: Prevents costly repairs and project delays due to utility damage.
  • Regulatory Compliance: Ensures adherence to safety and construction regulations.
  • Enhanced Planning: Provides reliable data for planning and decision-making.

Underground utility mapping is a vital practice that supports a wide range of industries and activities. By employing advanced technologies and adhering to established standards, it provides the accurate and reliable data necessary for safe and efficient infrastructure development and management.

Very knowledgeable and friendly staff. The job itself was completed to a very high standard and the drawings that were provided afterwards were incredibly detailed and accurate. We have used similar companies in the past but these guys were so much better than all of them put together. Would definitely use Subvision again and look forward to doing so.
