Reconstruction of engineering structures and engineering networks, landscape based on laser scanning technology

Abstract

The relevance of reconstruction of urban infrastructure has increased when solving modern tasks of sustainable development of cities and united territorial communities in the conditions of urbanization of territories, including engineering structures, engineering networks, and landscape objects. The active introduction of laser scanning technology in construction corresponds to the concept of "Industry 4.0" and provides a modern technical level of solving a wide range of tasks in the construction field.

During laser scanning, data is transmitted about the dimensions, orientation in space, the location of the supporting structures of the object, etc. With the help of this method, high accuracy of measurements is ensured and significantly saves time for object research. This technology makes it possible to obtain high-precision measurements of complex engineering objects, restore design documentation, create a 3D model of the object with sufficient detail for further processing in various software packages. Therefore, the article analyzes the directions of using laser scanning technology for the reconstruction of engineering structures, engineering and transport networks, the landscape of urban areas and wilderness areas.

The main areas of use of laser scanning technology for scientific research in construction are analyzed. The possibilities of this technology to integrate the data of 3D models obtained by laser scanning in BIM with other application programs are emphasized. In particular, such integration can be applied to the research of: elements of building structures; pipelines and their working environments; engineering networks, landscape in accounting and informational, billing, GIS software products for municipal institutions, enterprises; characteristics of energy efficiency of buildings and facilities, engineering networks. The development of such integration is constantly expanding.

Laser scanning technologies facilitate the task of developing a landscape project during the reconstruction of the territory with changes: in its development; planning solutions for transport and pedestrian routes, engineering structures and networks, landscaping and greening; designing objects of landscape architecture in the conditions of the existing restrictions of the territory from the side of buildings, relief and other factors of the territory of the urban environment.
