UNDERGROUND UTILITY SURVEYS

Underground Utility Surveys and Subsurface Mapping

At LandPlan, we provide expert underground utility surveys to detect, locate, and map subsurface services before construction or excavation begins. 

Using a combination of Ground Penetrating Radar (GPR), Electromagnetic Locators, and GNSS positioning, we identify the location and depth of underground utilities reducing risk, avoiding costly damage, and ensuring compliance with construction safety regulations.

Our surveys help developers, engineers, municipalities, and contractors make informed decisions when planning around underground infrastructure.

Underground Utility Survey Services

• Subsurface Utility Detection
  Identification of electric cables, water pipes, sewer lines, gas pipelines, communication ducts, and other buried services using non-destructive methods.

• Depth and Position Verification
  Accurate 3D spatial data including depths, alignments, and offsets of utilities relative to surface features and coordinate systems.

• Utility Mapping and CAD Plans
  Delivery of clear and detailed utility maps showing all detected subsurface infrastructure. Outputs are compatible with GIS, AutoCAD, and civil design software.

• Integrated Topographic and Utility Surveys
  Combined surface and subsurface surveys for design and planning, including roadworks, site development, and infrastructure upgrades.

• Construction Risk Mitigation
  Early-stage utility locating reduces the risk of hitting buried services, saving time and cost, and improving safety on site.
