Geodetic Deformation Survey is a field of surveying science which devises and builds points, collects observations, performs adjustments and analyzes geodetic control networks. Geodetic networks are a combination of pillars and target points whose coordinates (locations) are determined accurately.

Pillar: Geodetic network points located outside the structure.

Target Points: Geodetic network points located on the structure whose displacements are monitored and measured.

Geodetic Deformation Survey is an efficient tool for tracing and measuring vertical and horizontal displacements of dams, drill holes, tall buildings, bridges and power plants. It is one of the requirements for starting operation of dam-building projects.

  • Planning 3D geodetic networks to control stability of large structures such as dams, bridges, tunnels, towers and power plants;
  • Performing geodetic observations based on international standards using state-of-the-art surveying and geodetic instruments;
  • Processing and analyzing geodetic observations and preparing technical reports of observations and adjustment calculations;
  • Planning and implementing precision geodetic networks for building dams and related structures;
  • Planning satellite networks and building and installation of related points;
  • Satellite networks observations using dual frequency GPS receivers;
  • Analyzing structure deformations using finite elements method;
  • Planning and providing building details of pillars and target points; and
  • Building pillars and target points.
