This article discusses the system of construction control of capital construction objects, its participants and their interaction. Purpose: analysis of the building control system, interaction of its participants, determination of the main factors influencing the functioning of the building control system. Methods: the method of synthesis and scientific analysis was used. Results: the authors identified the main factors influencing the efficiency of the construction control system. Conclusions: the identified main factors provoke a decrease in the efficiency of the construction control system. The prospect of the study is further analysis of the factors to find their elimination.

Keywords: construction control system, interaction of participants, factors

In view of the trend of transition to the Western experience of construction, which implies the delivery of objects with a complete set of finishing works, developers and investors have a need to involve the technical customer service to carry out construction control, at the stage of finishing works. Since a clear system of controlled indicators has not been established to improve the quality of finishing works, this article is devoted to the identification of the main cycles of finishing works and the typification of the most common defects, with a reserve for the establishment of factors that affect the manifestation of these defects in the production of finishing works.
