This article is aimed at finding ways to accelerate the implementation of BIM by actively involving small businesses in the implementation process. A differentiated approach to the implementation of BIM has made it possible to determine that the scale of costs and changes in large and small organizations in the investment and construction sector differ significantly. Many of the factors hindering the implementation of BIM in small organizations are not insurmountable or are absent in a small organization due to the limited functions performed by it. Accordingly, the scale of costs and organizational transformations required by a small organization when implementing BIM is many times different from those needed by a large organization. Based on the differences in interaction models in a large and small organization when implementing a project using BIM, the main aspects of BIM implementation in small organizations are formulated, a methodology for implementing BIM in small organizations is proposed, taking into account their specifics and orientation to the requirements of the external environment. Active involvement in the BIM implementation process will significantly contribute to the spread of the technology. This will help reduce the amount of resources consumed (material, labor, energy, financial), reduce construction debris and emissions, and increase the economic efficiency of projects. The massive implementation of BIM in construction based on the involvement of small organizations will allow for an economic effect at the meso- and macro– level – the level of the region and the country due to the scale of the construction industry in the economy.
