Relationship between the building information model (BIM-model) and the estimated cost

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.
