Purpose. Research of methodological and practical aspects of improving the efficiency of construction project management using innovative approaches and determination of managerial reliability applying the principles of systems engineering in the conditions of transformation of economic relations of the construction industry. Methodology. An important role in the study is played by the formation of knowledge and skills to use a modern project approach to solving problems of management processes at different levels, focusing these processes on achieving end results with minimal time and money and mastering the methodology of construction project management as a new progressive tools in the field of construction organization. Findings. The paper analyzes the management processes of construction projects, usually due to a number of factors that affect the progress of the construction project. Methods for evaluating the effectiveness of investment construction projects, which are based on a single methodological basis, are considered. The results of introduction of the basic principles of system engineering as innovative approaches of increase of administrative reliability are substantiated. Originality. Based on the principles of systems engineering, as well as the laws of project management identified ways to improve the efficiency of construction project management through optimal choice of management and organizational and technological solutions through the ability of contractors to organize work by planning and regulating resources (labor, material, financial, technical) their interaction (intensity, sequence, combination) in order to achieve a given result. Practical value. The application of the concept of construction project management and the use of the principle of systems engineering is one of the main ways to increase the efficiency of construction project management to ensure the competitiveness of construction projects in the transformation of the construction services market.
