Introduction. The demand for interior design services (Fit-out) in Russia began to grow actively in recent years, so the research in this area, aimed at improving the efficiency of project implementation, is relevant. Despite the relevance of this direction in our country, in the scientific community the topic of interior design (Fit-out) is touched upon only in the field of BIM modelling. The stages of research on revealing the dependence of the choice of organizational and technological solutions by general contracting organization on the terms of construction project implementation in the direction of Fit-out are presented.

Materials and methods. Literary sources, scientific publications, Internet resources were studied. The analysis of design and estimate, production, organizational and technological, executive, tender, financial and reporting and other documentation, with which the studied factors affecting the efficiency of construction project implementation by general contracting organization in the direction of Fit-out are connected, is carried out.

Results. The dependence of the identified factors and the analyzed documentation is determined. The performance criterion — the period of realization of the construction project Fit-out is established. As a tool for assessing the efficiency of construction project realization “Complex indicator of efficiency of construction project Fit-out” is accepted. The formed system will be the basis for the development of a methodology for determining the efficiency of construction project implementation by the general contracting organization in the direction of Fit-out.

Conclusions. Completed projects are required to be evaluated for achievement of the company’s objectives and quality of work. These evaluations can serve as feedback for future projects and for process improvement. In addition, these evaluations can be used to make adjustments to organizational, technological and management decisions during the construction process to achieve goals.
