The development of the construction industry has both positive aspects of a social and economic nature, and negative ones - associated with an increase in the number of accidents, low quality of construction and installation work and the emergence of disputes between participants in construction production. The resolution of conflict situations arising in the construction industry between business entities is possible with the use of special construction and technical knowledge. One of the most demanded forms of application of such knowledge is judicial construction and technical expertise.

The relevance of experimental and theoretical studies of improving the operational efficiency of construction arbitrariness is justified. It is established that the operational efficiency of a construction site depends on many factors. In order to identify the main features of improving the operational efficiency of construction production in this study, we used a computer method of relative distribution of premises and computerized planning of relationships and layout. Some features of the system operation at increasing the operational efficiency of construction production are determined. Based on the conducted experiments, the need for further study of improving the operational efficiency of construction production is justified. Also, on the basis of a number of experiments, the influence of the operational efficiency of construction production on the economic aspect of construction was proved.

Modern design cannot be imagined without the application of BIM technologies. Modeling is increasingly used in the design of new construction of buildings and construction, renovations and major repairs, which makes up the majority of projects underway. 2D programs are still used for the inspection of buildings and construction. Visual and instrumental examination is not a difficult task requiring complex programs. But the introduction of BIM technologies ensures the acceleration of work on the inspection of buildings and structures, significantly improves the quality of the result, and also maximizes the actual condition of building structures.
