The technology of information modeling of buildings is a new tool for managing information flows in the implementation of a construction project. Based on the analysis of information flows in the activities of the construction organization, an integration methodology and a data flow interaction scheme based on modeling has been developed. The Knowledge Base is considered as an expert system, which interconnects design engineering models and acts as a transmitter of design solutions to estimated and financial decisions and a data accumulator for a decision-making analytical center. A factor analysis of specific costs for the production of construction products based on multiple linear correlation and regression analysis was carried out. The possibilities of machine learning and data requirements for the learning program are considered.
