Specialist detection & mapping
At Subscan our surveyors use a range of electromagnetic location methods, ground penetrating radar and visual inspection to provide utility mapping services to the highest standard. Each survey is presented in layered CAD models with an accompanying report ensuring you have all the information required to make informed, and safe, decisions on site.

We continually invest in the best equipment to allow us to offer you the very best levels of service. Our latest Ground Penetrating Radar can scan to a staggering 5 metres to ensure you get a more complete picture of the ground beneath your feet. Ground Penetrating Radar (GPR) is a form of non-destructive utility detection and can be used in a variety of materials including; rock, soil, ice, water and pavements. Electromagnetic radiation is used to transmit radar pulses below the surface. The GPR records the reflected signals to produce an image of the composition and location of sub-surface structures.
For contractors who are required to undertake excavation works at short notice, Subscan have a dedicated ad hock team who can be on site within 48 hours (location dependant) to locate and mark out underground utilities.
Subscan UDS offer different levels of survey. Please find below a brief explanation of each level of survey
- Level D Survey – Desktop Utility Records Search
- Level C Survey – Site Reconnaissance Survey
- Level B Survey – Detection and Base Map Update
- Level A Survey – Detection, Survey Location and Verification
Underground utilities and topographical survey
Subscan were appointed by Wessex Water to carry out a full underground utilities and topographical survey to areas within Hinkley Nuclear Power Station and collate all information into one document.

This is an ongoing project due for completion on site Christmas 2018 and will be produced in a complete CAD DWG format with relevant PDFs. All high resolution photos from site and written day to day survey reports will be collated into one document by our surveyors and presented to the client on completion.
“The Subscan UDS team of surveyors and drainage engineers helped our minor works team out again and did a thoroughly professional job. We will continue to work with Subscan on LNE projects throughout the region.”
