Our specialists perform a full range of topographical, engineering-geological and environmental surveys of any complexity.

Topographical survey

The most advanced technologies are used for surveying works: laser scanning (surface and aerial), modern methods of aerial survey. Land survey is performed with the optical and satellite-based devices.

Topographic survey is carried out in the scale of 1:200 - 1:25000. By means of the airborne laser scanning, digital terrain models and 3D-object models are produced.

The materials of aerial surveys are used:

  • to create orthophoto plans:

  • to provide situation monitoring;

  • to create high-resolution images;

  • to survey railway stations and hubs;

  • to certificate railway tracks.;

    Altimetric survey networks, points and boundary marks are placed using GPS and GLONASS. The Institute also performs cameral and field works on tracing railways and roads, geodetic survey of facades of buildings, survey of underground constructions and land cadastral works.

    We possess the Russia’s most advanced survey system Optech consisting of:

  • ORION-M-300 Airborne Laser Scanner. Its performance and accuracy parameters meet the highest operational requirements;

  • CS-10000 High-Resolution Digital Aerial Camera equipped with 80-Mpixel sensor;

  • GSM3000 Gyro-Stabilization Mount;

This equipment which is unique for Russian design institutes allows us to perform the full range of topographical surveys by means of airborne laser scanning and aerial photography. Such equipment is particularly effective for surveying long mileage facilities (tens and hundreds of kilometers).

The uncertainty of height measurements is no more than 10 cm and from 2 to 30 cm depending on the flight level.

The speed of data collection is about 120 square kilometers per hour. In comparison with ground survey, the costs for aerial survey are reduced by 20 times (this difference is significantly increased in inaccessible or dangerous areas).

Engineering-geological survey

In order to determine physical and mechanical properties of all types of soil and to test chemical composition of ground water by means of crawler drilling rigs and wagon drills, the following works are performed:

  • drilling wells for different purposes and soil sampling for laboratory analysis;

  • engineering-geological survey at any scale;

  • exploration of borrow pits and drainage soil;

  • soil field testing: core penetration test at the depth of up to 20-40 m, soil tests with a pressuremeter, dilatometer, stamp, including electrodynamic testing and testing for underground water inflow;

  • stationary monitoring of ground water regime;

  • geophysical surveys (seismic survey, geoelectric survey, magnetic survey, radiometric survey).

    Our engineering-geological laboratory is accredited by “Mossstroycertification” until July 225, 2020.

    The laboratory is equipped with modern testing, measuring and supporting equipment and performs the whole range of tests for determining constitution and properties of soils and natural waters, and forecasting their potential change during construction works and operation of the designed facilities.  

Environmental survey

Scientific attitude and detailed study of areas peculiarities allow us to perform:

  • sampling of soils, surface waters and bed sediments;

  • survey of vegetation and fauna;

  • measurement of noise and vibration levels, electromagnetic radiation;

  • radiological studies;

  • measurement of air pollution and noise impact by means of modern specialized software package “Ecolog”.

    In cooperation with local authorities, the Institute holds public discussions with the residents of the settlements and districts which will be affected by the construction works. The purpose of these discussions is to inform the public about the impact of projects on the environment and about the protection measures which will be taken.


Design projects for public and non-public rail tracks, in particular:

  • construction of new railway sections and reconstruction/improvement of existing ones including the construction of additional main tracks;

  • construction of new approach and crossover tracks and reconstruction/improvement of existing ones.

    The Institute develops projects for construction/reconstruction of all types of roads from highways to road networks of urban and rural settlements.

    Moreover, the Institute performs design works using Digital Elevation Model technologies and digital ortho-rectified aerial images of configurable resolution which reduce the design period. We develop:

  • alternative positions of linear facilities considering all natural and territorial limitations; optimal variants based on engineering and economical comparison;

  • roadbed designs for railways and motor roads including standardized and individual designs;

  • superstructure designs for railways;

  • road pavement using modern advanced materials.
