GPS (GNSS)
GPS, a common misnomer for GNSS (global navigation satellite systems), has nearly 30 years of experience in topography and geodesy. With the establishment of new Chinese, European, Russian and American constellations, the offer has been multiplied and today allows us to have very broad coverage of the territory, which we use with our receivers as support and complement to the solutions of classic topographic measurements.
Total stations and accurate digital levels
Classic topometry devices remain the basic tools for our profession as surveyors. Used on construction sites or for all field measurement operations, they continue to evolve. In addition to being precision tools, they are today facilitating tools for implementation, reporting and control
Laser Scanner
This technology consists of measuring 3D points at phenomenal acquisition speeds, up to several million points per second.
Thus, we resort to its use to measure large built complexes, such as apartments, villas or old farms, entire buildings in the process of renovation, or even during construction to allow us to compare the states as built with the BIM models which are increasingly used, and thus validate the different stages carried out, which, for some, will then never again be accessible for measurements.
The point clouds, assembled, calibrated and georeferenced, then allow us to process them and generate 3D models, for BIM in particular, which can sometimes go as far as the development of true digital twins.
Drones
The use of drones is very widespread today. We use this technology as a vector for acquiring aerial images to carry out photogrammetry.
The ability of drones to position themselves and see what we cannot see from the ground, makes it possible to produce images, orthophotos and point clouds of inaccessible or large-scale areas : roofs, facades, study areas of several hectares, structures, wooded areas, etc.
We use several types of drones, each more or less adapted to different configurations.
LIDAR and Mobile Mapping
The latest mass acquisition technologies, such as mobile mapping (pedestrian or vehicled) or aerial lidar scanning (often helimade), have become widely available with the evolution of the computing power of our modern computers.
Already today, inventory of several hectares is only carried out with these technologies.
Fast, reliable and precise, they make it possible to cover large areas ranging from a few hectares to an entire territory.
Moreover, the Territorial Information Department regularly carries out a complete overview of the Canton to produce two key tools: an orthophoto and a 3D model of its territory.
We use this data in particular to extract relevant information according to the needs of a project, data which we can supplement with additional measurements via combination with other technologies.
AI and cloud points traitments
The processing of point clouds, or more precisely the exploitation of geographic data and information in a point cloud, is an essential point after the acquisition of these point clouds. Without georeferenced processing, without appropriate modeling, acquisitions remain of little relevance. These treatments are therefore a very important part of our activity.
The immense quantity of data requires specific IT performance, as well as simplifying and organizing this information in systems that can be used by project authors.
Whether for classification or modeling assistance, today we use artificial intelligence to support us in these innovative computer treatments.
XR projectors and bimprinters
The repetitiveness of actions during implementation increases the risk of errors and reduces efficiency.
The increase in the complexity of the layouts to be carried out (curves, angles, concentration of equipment, etc.) makes traditional layout methods less and less universal.
These two simple observations led us to invest in robotic and alternative solutions maintaining high and reproducible implantation precision.
With the Bimprinter, we now offer new services in terms of quality and precision. Controlled by a total station, our autonomous tracing robot traces curves or lines in a built environment (interior or exterior of buildings). It opens up the field of possibilities for architects or designers of ground works.
With our very recent XR laser projector from Mechasys, we are able to carry out layouts by laser projection on the floor, ceiling and walls of selected elements from an execution plan.
With these recent instruments, we have tools that save valuable time while guaranteeing a minimal risk of error.
Monitoring and special instrumentation
The instrumentation or installation of monitoring devices makes it possible to monitor movements, variations or displacements (x,y,z) remotely and continuously without having to travel to site. Robotic total stations allow such monitoring, as well as an infinite quantity of additional sensors of all kinds : inclinometers, crackmeters, tassometers, geophones, thermometers, etc. We strive with enthusiasm to stay on top of developments in instrumentation every day, allowing us to offer you the most effective systems to monitor and monitor the stability of your installations and construction sites.
