In the process of construction and operation of objects of increased responsibility, it becomes necessary to monitor their deformations (precipitations, shifts, rolls).
Geodetic observations of deformations and displacements include measurements using geodetic instruments of horizontal and vertical displacements, both of buildings and structures under construction and those located in the zone of influence of construction in order to:
- timely establishment of critical values of deformations;
- identifying the causes of deformations;
- development and adoption of measures to eliminate negative processes.
There are observations of vertical (precipitation) and horizontal (shifts, rolls) displacements.
Geodetic measurements of the precipitation of the foundations of buildings and structures are carried out using precision digital levels, and shifts and rolls – using high-precision robotic electronic total stations.
To obtain a complete picture of the state of the object under examination as a whole, geodetic monitoring of cracks in its facades is carried out simultaneously with the observations of the subsidence of the building base.
As a result of observations of the deformations of buildings and structures, a technical conclusion is drawn up on the state and forecast of the development of the identified displacements, recommendations are made for taking appropriate measures to prevent the negative consequences of critical violations.
