Рассматриваются основные принципы управления проектом, этапы жизненного цикла объекта капитального строительства, а также требования к уровням проработки цифровых информационных моделей.</p><p>   Особое внимание уделяется взаимосвязи графических данных и атрибутивных параметров, а также параметрам валидации и верификации.</p><p>   Был проведен анализ затрат на разных этапах жизненного цикла, включая возведение здания и эксплуатацию инженерных систем. В статье было раскрыто понятие «управление проектом» и было установлено, что это замкнутый повторяющийся цикл набора обязательных действий. Представлено графическое изображение, отражающее понятие «этапы жизненного цикла объекта капитального строительства».</p><p>   Особый интерес при рассмотрении понятия «управление проектом» вызывает то, что конкретизированы требования к уровням проработки цифровых информационных моделей.</p><p>   В заключении подчеркивается значимость синхронизации процессов и совместной работы участников проекта для успешного выполнения строительных задач.</p></abstract><trans-abstract xml:lang="en"><p>   The purpose of this work is to improve the basic principles of creating information models of buildings, taking into account engineering systems.</p><p>   The article reveals the key stages of building a digital building model, taking into account engineering systems and emphasizing the importance of an integrated approach in modern construction. The basic principles of project management, the stages of the life cycle of a capital construction facility, as well as the requirements for the levels of development of digital information models are considered.</p><p>   Special attention is paid to the relationship between graphical data and attribute parameters, as well as validation and verification parameters.</p><p>   A cost analysis was carried out at different stages of the life cycle, including the construction of the building and the operation of engineering systems. The article revealed the concept of project management and found that it is a closed, repetitive cycle of a set of mandatory actions. A graphic image reflecting the concept of stages of the life cycle of a capital construction facility is presented.</p><p>   Of particular interest when considering the concept of project management is that the requirements for the levels of development of digital information models are specified.</p><p>   In conclusion, the importance of process synchronization and collaboration of project participants is emphasized for the successful completion of construction tasks.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цифровая модель</kwd><kwd>жизненный цикл</kwd><kwd>инженерная система</kwd><kwd>управление проектом</kwd><kwd>графические и атрибутивные данные</kwd></kwd-group><kwd-group xml:lang="en"><kwd>digital model</kwd><kwd>life cycle</kwd><kwd>engineering system</kwd><kwd>project management</kwd><kwd>graphic and attribute data</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Мошкалёв Д.С., Бахтизина А.Р.
