Spatial measurement techniques & monitoring

They say that if you measure it, you can manage it. For proof, you need look no further than the incar navigation systems used by millions of people every day to manage their journeys. In engineering circles, however, the importance of using precise information with the highest imaginable accuracy is even greater. Developments in this field have widened, and applications now reach into different segments of the market. Iv-Groep specialises in spatial measurement techniques. Our experienced measurement specialists are deployable for various services, including above-ground and below-ground monitoring, overseeing construction work, borings, Geographical Information Systems (GIS) and terrestrial 3D laser scanning.

Engineering work is increasingly impacting the immediate vicinity in a country like the Netherlands where the landscape is slowly but surely filling up with buildings. Deformation, vibration and noise measurements enable good above-ground monitoring so as to prevent damage or nuisance. Geotechnical measurements allow good below-ground monitoring. Other key matters for monitoring the surroundings properly include the preparation of subsidence predictions, vibration predictions and monitoring plans, as well as the correct interpretation of measurement data.

Sites in public spaces are demarcated by means of the dimensional characteristics of buildings or roads. Flexibility and accuracy are prerequisites in this respect. It is necessary to oversee assembly in the workshop or on-site to make sure that assets like movable bridges, lock doors, and port cranes work properly.

Iv-Groep developed COMET (COntinuous MEasuring Technology) for the uninterrupted measurement of the position of drilling machines for compressed air drillings. Advantages include the avoidance of drilling delays thanks to accurate dimensioning and the instant availability of as-built data.
Government authorities in particular correlate numerous pieces of data spatially in a so-called Geographical Information System (GIS). A GIS can be used to store, manage, edit, analyse, integrate and present geographical data. In a GIS, various kinds of data can be combined to create and share useful information.

Terrestrial 3D laser scanning
Three-dimensional measurements are commonplace in several markets. Terrestrial 3D laser scanning is a specialisation used to good effect in as-built situations. Laser scanning involves the use of point clouds for the accurate compilation and representation of situations. The technique can be used for a variety of different purposes, including surveying quantities of sand and traffic gantries, but also visualising complex spaces. A good example is the recording of clusters of pipelines in the petrochemical and offshore industries.

Iv-Groep has adopted a pragmatic approach. We have a high level of quality thanks to the merging of expertise obtained through the diversity of measurements and the use of our finely-tuned high-tech equipment. We ensure good and direct communication. The benefit for you as a client is that we relieve you of challenging issues and will openly share information with you as an equal partner. The end-product will be a reliable and accurate report delivered on time.
