Experience of the countries with stable market economy shows that the economic efficiency of construction depends on the organization of works based on the work schedules. In schedules the minimum indicators of value of works and period of their realization depend on the appropriate distribution of manpower and technical resources. Primary problems of reducing the construction cost, while maintaining its high quality are: timeliness of input of objects in operation and improvement of the work organization. Our studies have been aimed at a project cost reduction by optimizing the scheduling and organization of the construction process, i.e., through the development and application of the most efficient models of construction operations management considering the works at the level of simple technological processes and using the modern software products was done. According to the results of study the cost-effective methods are suggested to improve the construction scheduling. The improved methods of construction scheduling by considering the works at the level of simple technological processes can improve the organizational and economic feasibility of construction projects.
