Problems of using BIM in Variant Design of Reconstruction Processes in Underground Parts of Buildings and Structures Using Universal Machines

Building information modeling (BIM) is quickly transforming the construction sector, with significant improvements in project results. In recent years, as the construction industry has shifted from new building construction to building maintenance and usage, the need for BIM has increased. The life cycle of a building can be divided into several periods, the largest of which are the stages of design, construction, operation, and demolition of the building. The process of building information modeling mainly affects the building design and construction stages, minimally affecting the stages of operation and demolition. This is influenced by a number of factors, such as the low level of development of regulatory literature, or the lack of a modern technical base for the implementation of measures for the operation of the building using information models. As the development and use of BIM in new construction projects becomes more common, the construction industry begins to worry about and discuss the implementation of digital and intelligent management by creating As-is BIM for existing buildings and using BIM in the operation, maintenance, and building renovation or demolition phases. Processes of reconstructing underground parts of buildings and structures cause special challenges. This article summarizes the existing practices and concerns in this field, outlining vectors for further research and efforts.
