The article deals with current issues of the introduction of building information model technologies, which are a tool for digitalization of the construction industry, into the workflow of design organizations. The problems and disadvantages of the existing system in organization of joint work are revealed based on the analysis of the current state, assessment of internal and external factors that affect the management of the working environment within the organization. The general principles of the formation of a unified environment based on the use of information modeling technologies - the common data environment (CDE) are analyzed. The concepts of forming a common data environment with their subsequent analysis in order to identify advantages and disadvantages are considered. The article concludes that it is necessary to organize a common data environment through the use of specialized software that has significant advantages over other methods, the main of which is the ability to work with a consolidated model. A step-by-step plan for the implementation of the common data environment in the activities of project organizations is proposed. The plan is divided into four stages: the preparatory stage, the analytical stage, the testing stage and the stage of full implementation of the common data environment. Taking into account the identified problems, an improved methodology for organizing the common data environment in the design of the section 'Land plot layout scheme' has been developed. The methodology makes it possible to use the resources of the project company (through the use of building information model technologies) and ensure high quality and speed in the implementation of the project (due to the possibility of checking the model for collisions and creating conditions for data exchange) effectively, and, consequently, increase the competitiveness of the company in the market.
