In-depth experience with the various survey tools and technologies available on the market.
We offer high-quality survey services, backed by our knowledge of potential issues relative to the design and execution of engineering projects across our various areas of expertise. Our vast experience allows us to select the digital survey equipment and technologies that are best-suited to the client’s context and needs. From the survey of the existing situation to simulation of major maintenance (shutdown), solutions are gathered and incorporated into your work flow with a view to optimize your investment and achieve enhanced control of all parameters.
Analysis of verticality, flatness and deformation
With the high capture speed of the 3D scanner, it is possible to capture the existing condition of an infrastructure asset at a rate of millions of points per second, and to carry out a facade deformation or slab flatness analysis by generating a colour-gradient image to facilitate interpretation of the data.
Volumetric calculations
Volumetry is the measurement of a space or element in three dimensions. We have the ability to precisely calculate the volume of a tract of land based on a three-dimensional topographic survey (photogrammetry, topographic survey, GPS survey, etc.). This allows us to generate a digital terrain model that takes into account the volume, the spreading of the material and the slope.
Data extraction and 2D drawing
Using the thousands of points captured by a 3D scanner or drone during a survey, the information required to prepare drawings of the existing conditions can be extracted by means of various tools designed to optimize the use of this information. The files that are obtained can then be input directly into the CAD software for data extraction and the production of drawings.
Inspection of confined spaces
Using specialized remote-controlled equipment, it is possible to capture the existing conditions in confined spaces and carry out surveys efficiently and safely. By capturing LiHDR 360 images with millimetre-level precision, we can produce a reliable portrait of all visible components inside the confined space in just minutes.
Infrastructure inspection
Using drones and high-precision sensors, we are able to capture the existing conditions of infrastructure assets and conduct surveys efficiently and safely. Capturing high-definition images allows for the generation of a 3D model or orthophotograph, and for rapid consultation of the photogrammetric survey.
3D modeling
The point cloud that is obtained from a survey carried out using a 3D scanner or a drone can be input and used as a reference in CAD software packages, such as AutoCAD, Revit, Civil 3D, Inventor, 3DsMax, Infraworks, Navisworks, Sketchup, Microstation, Bentley Descarte, CATIA and Solidwork. There are many tools available for extracting and optimizing the use of point cloud data. Over the years, our technicians have developed expertise in the use of these various programs, and can efficiently convert 3D surveys into a 3D CAD model to generate a digital twin for conducting virtual simulations.
Orthophotographs
This technique involves processing aerial photographs using powerful software to obtain a three-dimensional image and a to-scale photomap, while deriving various measurements. Drone aerial orthophotography has interesting applications in many sectors, including agriculture, archeology, architecture, etc., and in particular, urban planning, land-use planning or the environment, environmental impact studies, prevention plans, landscape analysis or the revision of land-use plans (LUP).
Site supervision and quality control
Based on a 3D survey conducted using a 3D scanner or a drone, depending on the requirements, monitoring and quality control of the existing structures or of the work performed can then be carried out, along with site supervision. This makes it possible to characterize and index the as-built drawings over a given period and monitor the evolution of the site.
3D virtual visit
Using virtual reality (VR) technology, it is possible to simulate a site visit remotely, either in 3D or as a 360-degree view. The image representing the site being visited changes dynamically in response to the user's instructions. This technique makes it possible to visit buildings, industrial sites, confined spaces, museums or tourist sites, heritage buildings, entire cities and buildings for sale or rent, without having to travel to them.
