NIA MGSU: Laser scanning technique during construction of buildings and structures

2025: Introduction of Laser Scanning Technique

Moscow State Construction University (NRU MGSU) laser The method of scanning for construction buildings and structures has been developed. This method is already used in the construction of high-rise buildings To Moscow in and large industrial facilities in the regions. The university announced this on January 30, 2025.

The technology is designed to help reduce the measurement time of objects and reduce the amount of human resources. In addition, the laser scanning method avoids measurement errors that are inevitable in traditional geodetic measurements.

Modern construction requires high accuracy of measurements and control over the state of structures. Traditional geodetic methods do not always allow you to quickly and accurately record the parameters of objects in conditions of dense urban development or complex geometry of structures. Specialists of the Moscow State Construction University (NRU MGSU) proposed a solution to this problem - a laser scanning technique that allows detecting structural deformations and deviations from regulatory requirements with high accuracy.

The laser scanning laboratory operating as part of the Institute of Scientific and Technical Support of Construction (INTSS) of NRU MGSU is also engaged in the development and use of laser scanning methods during the construction of buildings and structures. Laboratory developments are already used in the scientific and technical support of the construction of buildings and structures in Moscow, as well as in the technical examination of industrial structures and existing industries. Among them are residential complexes more than 100 meters high on Wilhelm Peak Street and Academician Korolyov Street in Moscow, an electrometallurgical complex operating on environmentally friendly technology in the Nizhny Novgorod Region, one of the country's major scientific facilities - the Siberian Ring Photon Source in the Novosibirsk Region, as well as petrochemical enterprises in the Saratov Region.

As of January 2025, the construction of buildings and structures uses traditional geodetic methods based on the use of tacheometers, levelers and other geodetic survey devices. They remain effective in surveying small objects with simple geometry, however, for large-scale structures and complex objects, their accuracy and speed of work are insufficient.

Laser scanning is especially needed in dense urban environments, high-rise buildings and facilities with complex architecture, as well as in industrial enterprises that require fast and safe diagnostics. It allows you to minimize interference in the work of existing production facilities and quickly obtain accurate data for subsequent design and construction.

The technique developed at NRU MGSU includes the use of laser scanning to form a detailed cloud of points that creates a digital model of the object. The point cloud contains information about the spatial position and geometric parameters of the entire object and with any required detail, and not individual areas, as in the case of traditional geodetic survey.

Laser scanning captures the spatial position and geometry of objects with high accuracy, which makes it possible to analyze the state of structures at any stage of construction and operation. Unlike traditional methods, the technology allows for complete data on the building, including areas that may subsequently be restricted in access. You can return to the point cloud at any time without the need for repeated and additional geodetic measurements.

The laser scanning technique greatly expands the capabilities of technical inspection and monitoring of buildings and structures. With its help, it is possible to identify construction defects in the early stages and quickly eliminate them, which, in turn, significantly increases the safety of facilities during their operation.

The use of laser scanning significantly reduces the time required for geodetic work. This technique provides high speed and accuracy of measurements, which makes it possible to obtain initial data for subsequent processing. In addition, the technology allows you to minimize the human factor and errors in calculations.

Laser scanning is actively used in the process of information modeling at all stages of the object's life cycle. This, in turn, contributes to increasing the economic efficiency of construction through more rational use of resources.

The use of the technology reduces the time for technical inspection of buildings, reduces the total cost of monitoring and design by automating processes and improving the quality of input data.
