UNDERGROUND SURVEY, UTILITY SURVEY AND UNDERGROUND MAPPING
An underground survey is a specialised surveying that involves mapping, identifying and measuring the characteristics of subsurface structures and features, such as caves, mines, tunnels, and pipelines. Our underground surveyors experts follow the PAS128 standard. Adhering to the PAS 128 standard ensures the protection of subsurface utilities from damage during construction or excavation.
Depending on the type of utility survey, we deliver the following accurate deliverables when conducting an underground service:
- 3D utility surveys data capture and modelling
- 2D, 3D and 3D Modelled CAD
- GIS Model
- BIM Model
- MEP BIM Models
GPR: 2D and 3D technology. Towing and pushing systems with a broad range of frequencies
UNDERGROUND SURVEY SERVICES WE PROVIDE
Our CCTV drain inspections will gather complete analysis to identify any problematic blockages or damages and allow you to avoid any further complications in the future.
Using high-quality GPR equipment to complete precise ground penetrating radar surveys in a non-intrusive manner, we locate and identify any anomalies from below the surface.
SETTING OUT ENGINEER
Our experienced surveyors are incredibly skilled in site controlling and setting out positions, site boundary levels and columns to reduce the of mistake before construction.
3D LASER SCANNING SURVEYS
Capturing three-dimensional information about a physical structure through non-contact 3D laser scanning technology. Our laser scanning survey provides detailed deliverables no matter the scale.
Underground Survey Specialist
UNDERGROUND SURVEY SPECIALIST
The combination of skills, knowledge, and the latest underground surveying technology assures every client of accurate data, minimal risks, and effective results when detecting such objects below. Detection, location and verification of subsurface information give confidence and assurance in both the planning and construction of your projects.
Our head underground surveyor holds a PhD in Geodesy and Navigation, with an MSc in Surveying. With his extensive 12+ years of knowledge in surveying and management, we offer underground survey services to:
- Large-scale developments
- Underground and airport environments
In addition, our underground surveying department holds PASMA, PAL, and CSCS certifications, including harness training and inspection with Asbestos awareness.
METHODS AND EQUIPMENT WE USE
Our underground utility surveyors use powerful tools to obtain and analyse underground data to plan your projects. Several techniques can be delivered to target the type of underground service you require, including:
- GPR: 2D and 3D technology. Towing and pushing systems with a broad range of frequencies
- EML (Electro-Magnetic Locators)
- Mobile Mapping
- 3D Laser scanners. We use the latest laser scanning technology from leading brands such as Leica and Faro.
- Total Stations
- Software for drawings modelling and processing of the data
- Our own applications

UNDERGROUND SURVEY FAQ
Underground utility surveys focus on detecting, locating, and verifying all statutory services and other subsurface structures and features. This non-intrusive survey minimises the disruption and exposure to buried hazards while accurately recording underground utility features and locations.
Avoid excessive excavation and the modification of grounds and sites. Our experienced surveyors use the latest electromagnetic scan, Ground Penetrating Radar and their expertise to identify the subsurface environment and features when underground mapping. Our utility surveyors will identify all of the below features for a smoother process.
This equipment works by transmitting a pulse into the ground, which is recorded on site. The strength of the signal is transmitted back to the GPR unit and is translated into images of the objects underneath the ground.
Our team of experienced surveyors uses the latest underground surveying equipment to identify and produce highly accurate data on the subsurface environment to provide the vital details needed for your project planning including buried objects, infrastructures, layers under the ground, and services.
Our survey teams can help identify and document everything you may need for a construction project. BT and other Telecoms, Gas Supply, Water Supply, Electrical supply (both high and low voltage), Drainage (foul and surface) and subsurface structures will all be detected.
Depending on the depth and the type of utility being surveyed, underground mapping also has limitations, such as accessibility. That is why our team ensures that all means and efforts are executed using a range of techniques and tools to provide satisfying results.
