BIM Technologies in the Organizational and Technological Design of Civil Facilities in the Republic of Turkmenistan

The article examines BIM technologies as a tool for the organizational and technological design of civil facilities in the Republic of Turkmenistan. The research focuses on the functions of the digital model that influence the quality of design preparation, the consistency of architectural, structural, and engineering solutions, as well as the integration of design with scheduling and resource planning. The purpose of the study is to substantiate BIM as a digital basis for managing the design and construction process at the stages of preparation, design, construction, and operation of a facility. The methodological basis includes an analysis of scientific publications on building information modeling, digitalization of the construction industry, development of organizational and technological documentation, and management of construction processes, as well as materials on the state of the construction sector in Turkmenistan. It was established that the transition to a digital scheme for developing organizational and technological documentation reduces the time required to prepare its individual elements by 28-43%, labor input by 28.6-33.3%, and the time needed for introducing changes by 50-75%. The highest intensity of BIM application occurs at the design stage and reaches 65%, while at the preparatory stage it is 51%, during construction 50%, and at the operation stage 55%. It is shown that the practical effectiveness of BIM is determined by the completeness of attributive information, data compatibility, interdisciplinary coordination, and the readiness of project participants to work in a unified digital environment. The obtained findings may be used to improve the organizational and technological design of civil facilities in the conditions of Turkmenistan.
