The use of BIM technologies in the construction of a modern Allegro railway wheel manufacturing plant in the Titanium Valley Special Economic Zone in Verkhnyaya Salda

 The article examines the specifics of the use of building information modeling technologies in the construction of a modern Allegro railway wheel manufacturing plant located in the Titanium Valley special economic zone in Verkhnyaya Salda. The prerequisites for the introduction of BIM for this largescale industrial project, the methodology of its use at the design stage, including the choice of software and the organization of collaboration, are considered. The advantages achieved through BIM are analyzed in detail, such as improving the quality of design solutions, effective coordination of sections, and speeding up the release of documentation. A mathematical model for estimating the economic effect of collision avoidance is presented, based on average estimated data, confirming significant cost savings. Special attention is paid to the potential of using the created BIM model at the plant's operational stage as the basis for a digital twin that helps optimize maintenance, resource management, and incident re
sponse. The experience of the Allegro project demonstrates the high efficiency of BIM technologies for the implementation of complex industrial facilities, confirms their role as a tool for digitalization of the 
construction industry and is a successful example for replication in other large investment projects.
