Civil Engineering and Construction

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.

Quarry surveys

Quarry surveys

Periodic surveys of quarries for accurate and reliable monitoring.  In the same way as for volumetric surveys, the point cloud is a particularly suitable form of data. It can be obtained in different...
