on the territory of Central Asia and Kazakhstan
Topographic Surveying Works

These works are intended for the obtainment of the accurate, reliable and timely materials and data (in digital, graphic and other forms) about the situation and the relief of area; about existing buildings and constructions (ground-based, underground, elevated) and other components of planning needed for rational economic use of the territory; for efficient operation and removal of objects; for justification of the preproject documentation; for designing and construction of the new facilities, expansion, reconstruction and modernization of the operating facilities; for creation and keeping of the state cadastres (land, city planning etc.); for formation of the technical inventory accounting systems of the real property; for territory management; for realization of civil and legal operations with the real estate.    

                                              The works include:


·  Collection, analysis, computer processing (digitization) of the archive plan and cartographic materials;

· Territory reconnaissance survey;

· Implementation of altitude plan reference and survey justification in the form of the network of fixed beacons;

· Engineering topographic land survey of various scales;

· Search, detection and topographic survey of the underground utilities;

· “Office” processing of the received results;


· Creation of topographic maps of various scales, engineering and topographic plans, the summary plans (charts) of engineering utilities and constructions, thematic maps and atlases;

                                     · Technical reporting; 



The large-scale topographic surveying of the territories of the areal and linear objects is usually made instrumentally, with use of the modern electronic tachometers, the satellite GPS- equipment, the laser tapes and the field computers. The wide application of the field coding of the surveyed objects allows the minimization of time spent for subsequent “office” processing and the significant improvement of work efficiency.

The source plan and cartographic material, the aerial survey data, the results of the engineering survey are digitized and used for the office tracing of the linear objects in the automated mode.

The use of the preciseone-frequency GPS-equipment for the altitude plan geodetic referencing and creation of reference justification along the route allows the avoidance of traditional geodetic constructions (of progression and leveling lines), the high-resolution layout and field tracing in real time that considerably enhances the productivity and quality of works.

The surveying for the construction and operation of facilities.

Survey works and in-situ project implementation, layout of the basic and assembly axes, elevations and grades are done by means of the in-built software of the used geodetic equipment.  On the construction sites, the laser elevation meters and devices of the vertical projection are widely used.  The control of the geometric parameters and quality of construction is realized on the basis of the results of the realized surveys.



Our company possesses highly qualified experts, who have wide work experience.

All works are carried out in the shortest time, and the results are given to the customer in paper and electronic versions. All works are carried out with the use of the modern geodetic equipment.

The office data processing is done with the use of the latest computer equipment and software.
