Industry Base Classes as a Tool for Determining the Volume of Construction Work
Object. Industry Foundation Classes (IFC) act as the universal format of data for the digital description of the construction project. However, they are first of all applied to transfer of geometrical and physical data between computer-aided engineering systems. These data can be insufficient for the information transfer to other participants of construction. Methods. Industry Foundation Classes is the main semantic part of the open standards. They play the role of universal language of communication between computer technologies and appendices. They can be applied in the languages of object-oriented programming directly in the form of classes. Classes describe the elements of building structures, space partitioning of buildings and structures, geometrical and physical properties of elements as well as their relations among each other. The bases of the classes structure are described. Findings. Some disadvantages of the format constraining the broad use of information technologies during modeling buildings, are revealed. Thus, despite complexity of a format, there are no descriptions of many used building structures in the list of the main classes. There is no description of structures of underground, transport, hydraulic engineering and other constructions. Unloading of the CAD drawing and the return loading in the same system does not provides complete information transfer in all the cases. The development of the CAD concrete systems advances possibilities of the universal format. Conclusions. Some disadvantages of the IFC format, such as insufficiency of the data structure for the selection of the installation and construction works corresponding to the constructive solution of the building, come to light as the result of the research. for completion It is necessary to conduct purposeful dialogue with the user for the elimination this shortcoming
