Improving the calculation of the cost of the construction project using BIM technology

In the scientific article the authors summarize the results of theoretical research and practical implementation in the design of residential and public buildings BIM - information modeling technology. The questions of application of digital models for control of financial expenses at all stages of project implementation in construction are considered. An attempt is made to harmonize BIM technology with the Comsol Multiphysics software package. A review of existing studies on this issue in Europe, Asia, the United States and Russia. With the participation of the authors of the article developed a set of specialized families for the system Autodesk Revit, which allow you to perform a comprehensive preliminary study of the construction site of residential buildings. The approach providing increase of efficiency of determination of estimated cost of works on construction of object of construction based on several generalized principles is offered. This innovative approach has been tested in the design of several large construction projects in the Ural region of Russia, implemented in 2017-2019.
