3D MONITORING / DEFORMATIONS of buildings and lands can be determined by geodetic methods using: classical methods (total stations), GNSS methods (global positioning systems: GPS, GLONASS, Galileo) or combined methods. The geodetic network formed by control points and object points materialized on the body of the studied object is created so that following the monitoring campaign it is possible to determine the absolute three-dimensional movement of the studied object. The position of the object points is established based on a monitoring location project executed by the general designer. In the case of monitoring the behavior of the constructions in time, during the execution and then in exploitation, the monitoring project will be considered with the aim of measuring three-dimensional displacements starting with the pouring of the leveling foundation and ending with the commisioning of the construction.

Used equipment
Trimble S6, S5, S8 total stations (with 2 ”and 3” angle accuracy | 2mm + 2ppm distance accuracy), Trimble & Stonex GNSS equipment, Leica RTC360 laser scanner. Depending on the configuration and the measurement method, the precision for determining the displacements / plane deformations is in the order of ± 1mm – 3mm.
To achieve this high accuracy the measurements are adjusted with specialized geodetic software using the least squares method. Each adjusted report contains: the most probable values of the adjusted coordinates, as well as the standard deviations and the values of the measurements corrections.
Execution term
1-3 working days from the moment of placing the order
