PREFAB: NEW TECHNOLOGIES AND PROSPECTS OF THE CONSTRUCTION INDUSTRY

Statement of the problem. The main factors in the construction industry are: the cost of the project, its duration and uniqueness. Their achievement is facilitated by the currently developing pre-fabrication, the essence of which is reduced to the factory or factory manufacture of parts with their subsequent assembly into structural elements, modules and objects in general. At the same time, technologies, organization of construction and management of prefab processes have not been worked out to date. Results. A systematic review of the implementation of buildings using prefab technology with high factory readiness is proposed. An overview of modules that can be integrated into on-site projects with less waste and higher quality control compared to projects that use a traditional type of construction is provided. The difference between the prefab method and the modular assembly of a construction object is emphasized. An overview of the prefab products currently on the market is given. Conclusions. The article substantiates the directions of improving the quality of manufactured buildings inherent in prefab technologies, as well as the environmental friendliness and energy efficiency of this technology. A fragment of a BIM model with a calendar and construction schedule for the construction of a prefab house, prefab technologies used in Russia and in particular in Novosibirsk, is presented.
