Development of building information classifier elements to create and maintain information models of capital construction objects in terms of design processes, construction process management and construction information

Introduction. Integral approach to the application of construction information in the creation and maintenance of information models of capital construction objects is key in the constant development of construction activities. Besides, according to the global trends, the direct implementation of construction activity including construction of especially complicated and unique objects and typification of classical ones requires application of a unified system of building information classification to optimize duration, costs and improve the quality of the constructed object. Development of the Russian classifier of building information was the first step in this direction allowing to make a tool which is the unified system of building information classification generally available. The Russian building information classifier developed in 2020 contains a lot of elements among which we can distinguish those groups which allow to manage the cost, duration and quality of the future capital construction object both at the early stages of its life cycle and later: management processes, design processes and information. Materials and methods. International systems of classification of building information that have found wide practical application in the field of construction: OmniClass (USA), Uniclass 2015 (Great Britain), CCS (Denmark) and CoClass (Sweden) are considered. The analysis of the structures and composition of existing classification systems, as well as the analysis of the current regulatory and technical framework in the Russian Federation in the field of construction in areas related to the management of processes, design of capital construction object and its information entities. Results. Taking into account the analysis and generalization of world practice in the field of construction, and classification of building information, parts of the building information classifier adapted to the specifics of the national base of normative and technical documentation in construction, applicable to the design and management of capital construction object, as well as for its description, were developed. The structure recommended by the standard ISO 12006-2:2015 is adopted as the basis for such classification tables of the building information classifier. When developing the composition of the classifier, the requirements for unification and standardization of existing national classifiers and experience in the construction industry on domestic and foreign objects were taken into account. Classification tables of the building information classifier for the two areas of activity in construction (Management, Design) and a classification table describing the information entities of the capital construction object were developed. Conclusions. Classification tables “Process Management”, “Design Processes”, “Information” of the building information classifier in the developed structures and composition provide the formation of a unified structure of management and design of capital construction object, allowing to combine its parts for adaptation to the requirements of a particular object and organization. Thus, providing an opportunity to optimize its technical and economic indicators, including the duration of construction and the cost of the object in the extent of its life cycle, to develop a tool for typing design and management processes, including planning tools and quality and cost control. An additional tool for the interrelation of various activities in construction (e.g., design, operation, construction, etc.) is the developed classification table “Information”, which describes the information entities of the capital construction object.
