Formation of an effective schedule of work during the construction of a monolithic reinforced concrete house

Introduction. The existing principles of construction organization, based on early developments that do not take into account the current situation, to a large extent become an obstacle to the development of the construction industry. The current situation requires the introduction of new approaches in construction management, allowing to adapt to changing economic conditions, and contributing to a reduction in the duration of construction. The task of the study was to develop a project for the organization of work, which allows reducing the time for the construction of a monolithic floor from 14 to 6 working days. The scientific novelty of the work lies in the development of such combinations of various technological stages that made it possible to reduce the duration of construction without violating construction production technologies; to make decisions promptly in a specific situation and maintain full control over the consumption of building materials, possible losses and labour costs not aimed at fulfilling the main tasks, in order to improve the technical and economic indicators of construction.Materials and methods. Standard technological processes and regulatory documents were studied. It is revealed that the optimization of technological processes and the use of the principles of “lean construction” contributes to reducing labour costs and consumption of building materials, increasing productivity and improving quality; the development and implementation of technology depends on the final goal and task of the project, implies a sequence of decision-making.Results. In the course of the research, an algorithm for making specific decisions was developed. To achieve this goal, an analysis of the technology of monolithic housing construction was carried out, the moments that have a direct impact on increasing the duration of construction and possible losses were identified, and options for making changes that contribute to solving these problems were proposed.Conclusions. The proposed work organization system may have great potential in the future, despite its simplicity. The developed technical and technological solutions aimed at a lean attitude in production and organization of construction will greatly contribute to improving the competitiveness of construction companies, reducing the cost of production by reducing direct costs, increasing productivity and improving product quality. The stages of further implementation will be built entirely on the justification and development of a lean construction management model, and steps to implement this system, determining the area of responsibility of each participant.
