Non-Intrusive Utility detection

Interpreting old files

 

Old stocks are an essential part of a utility survey. We often find that old records are not (or only partially) available. The use and field validation of these files is of paramount importance when creating new digital files.

Classical geodesy

 

Our company is of course also active in traditional geodesy. Whether it’s land marking, building marking, building elevation, subdivision, land consolidation, utility surveying or even industrial geodesy – often requiring mm accuracy. Our company also provides expert advice, so we can offer our clients the best solutions.
 

 

Locator research

 

The primary tool for utility surveys is the electromagnetic locator. A signal generator is used to send a signal into the metallic conducting cables / pipes which “run” through the cable / pipe in a longitudinal direction. The generated signal can be detected by a receiver on the ground and its exact position can be determined – including depth!
Electromagnetic locators cannot be used on plastic pipes and fibre optic cables due to the laws of physics. In these cases we use ground penetrating radar.
 

 

Georadar research

 

We have different types of ground penetrating radar available, which we use according to the customer’s needs, depending on the task to be solved. The right choice of ground penetrating radar is of paramount importance, as the wrong choice will not help you achieve the desired objective. Whether it is soil composition investigation, archaeological research, utility mapping, concrete structure research or bridge structure investigation, our company can advise and offer solutions for any investigation.
 

 

CAD

 

CAD stands for Computer Aided Design. In engineering practice, it is one of the most widely used programs, in practice, the measurement results are edited in these programs, helping the work of contractors and designers. The design can be 2D or 3D, where the drawing and its associated objects are given the appropriate elevation in relation to the terrain.

 

 

CAD Model

 

Digital building solutions are nowadays one of the most dominant trends followed by design offices and construction companies. In the construction industry, it is slowly becoming essential that measurements are not represented in three dimensions. In addition to the X,Y coordinate, the data is also given a Z, or height, in the measurements. If field measurements are accompanied by a sufficient amount of data, this can help to produce a spatial model where the above or below ground extent of land features is represented in scale. This is of vital importance to design firms, especially in areas with high built-up areas.
