Underground Mapping and Underground Surveying
A full underground survey is the most comprehensive mapping service on the market. Geotec uses complementary techniques, such as lift and look, magnetic and radio frequency indication, ground penetrating radar and other techniques to reveal what is under the ground.
Accurately tying in all the underground details utilising theodolites to ensure the layers of information are added to the map, Geotec builds up a comprehensive picture of the site above and below ground.
Sites can be marked out there and then but the survey is not complete until the surveyor has transferred all the data received onto a clear AutoCAD drawing of the entire survey area.
Geotec takes pride in the fact that the senior surveyor on site is also the one who creates the map, providing complete ownership of the project. The survey provides vital data to the design and construction teams. Geotec can locate:
- Hidden services (water, power, gas, communications)
- Non-metallic services
- Voids
- Disturbed and saturated soil
- Unexploded ordnance
- Other hazards
You can prove your route and determine whether existing services need to be re-routed and pinpoint exactly where trial holes can most safely and effectively be dug.
Underground Surveying Work Environments
We have provided underground mapping and underground surveying services in a variety of environments; these have included retail districts, business districts, public highway, water treatment works, pumping stations, schools, airports, railway trackside, electricity sub stations, cemeteries, and open green-field sites. The techniques used enable us to map the underground environment for buried utilities, of any construction, and anomalies such as voids, tunnels, cellars, foundations or other obstructions.
Benefits of Underground Mapping
- improved work safety
- minimised disruption to road users and pedestrians
- avoided project delays
- provided accurate data for planning and design
- reduced damage risk to buried apparatus
- minimised unnecessary excavation
