REPAIR, DESIGN AND CONSTRUCTION OF CONTROL MEASUREMENT SYSTEMS (CIS), DEFORMATION MONITORING – this is a service that involves the carrying out of precise geodetic measurements in order to monitor and monitor already-made engineering facilities and buildings

Sites subject to such monitoring may vary. From an ordinary residential building to a complex and highly responsible engineering facility, such as a dam wall „ Tsankov kamak“ for example.

Geodetic measurements from the control measuring systems shall be carried out in accordance with a special methodology with pre-calibrated high-precision geodetic equipment: one- or two-frequency GPS, digital level and inverse or wooden bar codes, secundary total stations and associated auxiliary equipment.

Regardless of the type of subject subject to control and monitoring, the monitoring of the deformations requires the existence of a special & nbsp; network of several - control, support, orientation and other types of geodetic points. They have a specific construction and are stabilized (built) on the terrain according to a special methodology.The goal is to remain stationary in space during the entire monitoring period of the facility in whose interest the geodetic measurements (from one to several decades) are performed. The set of all points included in this specially built network form the so-called CONTROL MEASUREMENT SYSTEM - (CIS).

There are special instructions and normative documents regulating the rules and norms for the design of suchcontrol measuring systems and the organization of geodetic measurements from them.

Geodetic measurements from the control measuring systems shall be performed according to a special methodology and during certain periods of time. The time intervals between geodetic measurement campaigns depend on a number of factors: recommendations of the Chief Constructor of the facility, the elapsed time from the moment the facility is put into operation, the construction features of the facility, etc. 

In its practice Precise Engineering has several built and reconstructed onescontrol measures systems between which are extremely important and responsible control measuring system built in the area of ​​TPP & Maritza Iztok-2“

Geodetic measurements from the control measuring systems are performed according to a special methodology with pre-calibrated high-precision geodetic equipment: one or two-frequency GPS, digital levels and invariant or wooden barcode lats, second total stations and related auxiliary equipment.
