Methods and equipment we use
Our underground utility surveyors employ advanced tools and methodologies to gather and analyse subsurface data. Depending on your project’s needs, we utilise a variety of techniques to target specific underground services, including:
- EML (Electro-Magnetic Locators): These devices are used for accurately detecting buried utilities and metal objects.
- Mobile mapping: A method used for collecting high-density data over large areas, ideal for urban environments.
- GPR (Ground Penetrating Radar): Using 2D and 3D technology with towing and pushing systems for versatile frequency ranges, GPR provides in-depth analysis of underground conditions.
- 3D Laser scanners: Using the latest technology from industry leaders like Leica and Faro, we create accurate drawings and 3D models.
- Total stations: It allows for precise measurements and positioning of underground utilities in relation to the site.
- Software for drawing, modeling and data processing: We use advanced software and proprietary applications to process data and create detailed utility maps.
