The study evaluated the effect of the spring position in the panel on the amount of force required for vertical pushing of the columns. The results show that the farther the spring is from the hinge, the less pushing force is required to lift the column. In this method, the column was connected to the panel by hinged hinges at the factory, which allows lifting elements by crane as a single group during the installation of the frame structure on the construction site. In addition, a spring is installed on the panel at a certain distance, helping to push out the column and secure it. In this article, a threaded connection of precast reinforced concrete columns is proposed, which can be used to connect elements of fully assembled buildings and structures. The contact-screw connection of precast reinforced concrete consists of an upper and lower column, both have a cylindrical steel external thread in the end section connected. The strength of the screw column connection is determined by ensuring the transmission of axial loads and torque in the joints, ensuring the destruction caused by cutting and thread confusion that may occur between the connected columns. By means of the necessary calculations for the screw connection of columns made of precast reinforced concrete the corresponding rigidity and strength were confirmed. The new connections will contribute to the development of construction, its energy efficiency and acceleration of the installation process. These are effective approaches to reducing effort, time, and labor and energy costs.

The main maintenance of a diversification Based on the results of the studies, analysis of standards, taking into account the modern level of construction technology proposed and justified evaluation criteria installation of constructions of spatial modules of various types, and modifications produced by industrial methods, including "sandwich" or combined structures that dictated VA-reantaso construction projects. The formation method of installation is to find sustainable solutions through continuous analysis of components of organizational and technological structures. The present study represents the experience of a systematic presentation of the technological foundations of the analysis of efficiency of engineering solutions in the construction of buildings of the modules and quality control of construction works. The author believes that such a science-based framework that is able to provide a robust framework and methodology for designing rational processes of construction of buildings of the modules, can and should be a detailed analysis of the interrelated factors of construction, which, together, determine the level of efficiency of technologies of construction of buildings of the modules. During the development of mechanized technology, the modular construction of the proposed model the sequence of design stages.of production as activity of subjects of managing is considered. being shown in purchase of the operating enterprises, the organizations of the new enterprises, redistribution of investments in interests of the organization and development of new production on available floor spaces. The most important organizational economic targets of a diversification of management are presented by innovative activity of the industrial enterprise.

In today's construction business is very often the case related to the delay of construction. The transition to a market economy obliges to revise the old methods of organizational and technological design. Analysis of domestic, foreign literature has shown that we have a lot of experience in organizing and planning the work, but the timing of the development of project documentation is currently not regulated anywhere. But the construction period also depend on the speed of preparation of project documentation. This article deals with a new approach for planning the construction work based on existing methods of organizational and technological design. We analyzed the situation in the market of construction of residential real estate. The article describes the methods of work with network models with closed loops. Taking into account established principles, provisions and requirements of the paper proposes a graphical conceptual model for finding cycles in a closed loop. The formulas of finding cycles using matrix multiplication
