RELATIONSHIP BETWEEN THE BUILDING INFORMATION MODEL (BIM-MODEL) AND THE ESTIMATED COST

Abstract

An information model of a construction project (BIM-model) is an integral part of the project at the design and construction stages now days. The BIM-model contains parametric data about the object, the resources used and serves as a basis for making, as a rule, technological decisions. There is a need to transparently indicate the connection between the BIM model and the cost of the object, which is a key indicator when making management decisions. The information model is implemented in the IFC format, and estimating programs do not support this option for data transfer. In particular, the transfer of estimate data occurs using XML files. This discrepancy requires revision at the conceptual and software levels, including organizing a common data environment. The purpose of the work. The article is related to identifying the connection between the properties of the information model of the object and the estimate properties that should be included in the model parameters at all stages of the object's life cycle. Materials and methods. In the process of writing the article, general scientific methods and research techniques were used: descriptive method, comparison method, analogy method, generalization method, and systems approach. In preparing the work, the data of regulatory and methodological documents in the field of information modeling in the Russian Federation and international standards for the content and filling of the information model of the object were used. For testing, design and estimate documentation for the repair of an element of an administrative building was used. Results. A feature of the work is the development of the filling of the BIM-model with estimate properties depending on the level of development of the model (LOD), taking into account the requirements of regulatory and methodological documents in the field of construction and international standards. A method is proposed for the formation of a set of estimate properties, which can be further adapted to the needs of the customer depending on the type of construction, stage of the project life cycle and estimate standards. Conclusion. The results of the work can be used to form methodological documents on the organization of the general data environment at the stages of the life cycle of a capital facility.
