Surveying for civil engineering and the construction industry is an integral part of our activity, from the design process to setting out, as-built surveys and subsequent monitoring.
TPLM-3D is employed by consulting engineers or main contractors to set out alignments, curves or reference levels for buildings and structures at a variety of stages of construction. Our activities include setting out of alignments during excavations, of foundation piling, of anchorage systems and of reinforced concrete walls as well as surveys of existing structures for monitoring purposes or for future projects.
Our methods are also very suitable for the linear nature of road and railway projects, especially for profile surveys and deformation analyses.
In quarries and in ground investigations more generally, our site surveys are effective, accurate and comprehensive, and are performed in complete safety. Our products provide an excellent basis for structural and geomorphological analyses.
For regional development and other projects of large extent, we make use of techniques and methods which will provide you with georeferenced data covering very large areas: lidar from helicopters or drones (UAVs) and GPS campaigns.
Created from point clouds in conjunction with photographs, 360° panoramic visualisations give an excellent understanding of the existing site as well as a rapid measurement capability.
A virtual reconstruction of the geometry of the object, the 3D model is the preferred medium on which to base your plans.
The BIM structure adds intelligence to your 3D models. Once the model is structured it becomes universally useful ! Numerous information-rich by-products can then be easily created.
Elevations and horizontal and vertical sections enable the viewer to access the detail of the measured object and to understand the complexities of the whole site.
Quality and accuracy of your completed structures … benefit from quality control delivered by an external and independent surveyor.
When ultimate accuracy is at stake our techniques and equipment are at your service.
This product uses the point cloud derived from laser scanning or photogrammetry, in the form of a simple orthorectified image.
Exhaustive and accurate monitoring … our processes enable flatness to be checked or deformations to be quantified.
This complete basic dataset emerges directly from our measurements. It is a digital archive of the measured object but at the same time it provides you with the opportunity to extract any type of plot or of 3D model.
Periodic surveys of quarries for accurate and reliable monitoring.
Greater accuracy, greater flexibility … we operate at every stage of your project to set out the reference points required for construction.
Construction sites large and small … our techniques and experience are at your service for all your measurements and setting-out works.
The topographic map shows the existing situation on the ground, and is needed at the outset of your project.
Laser scanning ensures exhaustive data capture within a tunnel ; the subsequent processing provides both a survey of the existing situation and a check on the structure gauge (checking of clearances).
Our survey methods are particularly well suited to bringing ever greater precision to volume measurement.
