The purpose of this study is to determine the deterministic meaning of the term “Cluster of urban residential development” used in organizing the re-profiling of urban areas taking into account the organizational and technological model of production reliability. When implementing such projects, a set complex of combined tasks of an organizational and technological profile is solved and a number of parameters are taken into account (comfortable living, with rationally used free space; a combination of residential buildings with social, educational, cultural, everyday and entertainment facilities, etc.), as well - the basic principles of the formation of the reliability of the organizational and technological model of a cluster of urban residential development. The fundamental scientific hypothesis is that using the methods of organizational, technological, as well as numerical modelling and system engineering, the indicators of the integral reliability of construction manufacturing can be increased. As a result of the study, the cluster parameters of the urban residential for use in the complex model are established.
Features of renovation of built-up areas are considered. The main difficulties in carrying out the renovation process are identified. The concept of the constraint factor of the building is defined. Methods. A method for analyzing and assessing constraints for selecting optimal organizational and technical solutions for the renovation of territories is proposed. Results. An analysis algorithm is proposed, based on the consideration of the constraint factor as an array of actions of individual “objects of influence” on the corresponding “subjects of influence”. Conclusion. Сonducting such an analysis will provide the most effective and optimal organizational and technological solutions reflected in the relevant sections of the renovation project in high-rise construction (development of a construction master plan, preparation of calendar and network work schedules). The implemented rational version of the design solution ensured the reduction of the prime cost and the reduction of the terms of the preparatory works for the renovation of housing construction projects taking into account seismic uncertainty. Renovation is one of the varieties of this reconstruction of high rise construction.
Construction reorganization, as a type of construction of high-rise buildings, is a part of a basic reorganization cycle. Features of renovation of built-up areas and issues of energy modeling are considered. The experience of assessing the efficiency of quality management systems for the organizational structures of construction management and common approaches to solving this issue are currently insufficient. Loft style methodology is used: the integrated performance indicator of organizational and technological operational reliability (OTOR) in high-rise construction. The possibilities of the construction method using 3D printing technology are considered. Comparative analysis of cost indicators for the construction of walls made of concrete blocks with plaster, brick cladding and ApisCor technology is made. These circumstances allow formulating the scientific task of the study. On the basis of the well-known BIM technology for information modeling of objects, a bank (information base) of standard implementation plans (IP) is created, from which the most rational IP for this type of work is selected using the criteria research method based on modified genetic algorithms (GA). The issues of choosing a method of construction work by the totality of implementation plans of construction and installation works are considered.
Implementing the modern technological methods is recommended in the article, as well as performing some operations. It should be considered that small and medium-sized enterprises involved in the construction of industrial and civil facilities are also installing the roof coverings. The algorithm of technological operations is as follows: preparatory work; gluing a two-layer waterproofing roofing on freshly formed reinforced concrete panels; double rolling of the uncooled roll roofing after removing the panel from the steam chamber. The process of installing the waterproofing roofing has to be carried out in a specially equipped enterprise area. It is recommended to use the following domestic and foreign tools and equipment for above-mentioned operations. Such equipment is a truck crane (for example, KS-45717), a roof crane (KL-3), a temporary fence, a metal ruler, a tape measure, roller or a brush, a scraper, a roofing knife and a roller (weight is 100 kg).The rational methods of roofing installation (based on labor intensity) are presented. As was substantiated, the calculation of labor can change while improving the technology and the tools and equipment used. The quality control of operations is described, it involves visual inspections and the necessary measurements performed with a ruler. Optimal organizational and technological solutions, which allow to manage processes taking into account the safety of workers, were obtained. Fulfilling the labor safety requirements during construction (part 1 and part 11) is primary while installing the roll-up waterproofing roofing made of melting roofing material with the help of a solvent. In addition, it should be noted that the workplaces and storage locations with flammable materials and substances have to be provided with a portable fire stand, as well as with fire extinguishing and medical equipment. The conclusions and recommendations on organizational and technological solutions forin stalling the prefabricated roofing from roll materials by using mechanization means are presented. They are intended for developers of organizational and technological documentation, including flow charts, work projects, regulations, codes of rules. They will be useful for students, masters, graduate students studying for professions related to the production of building, erection and special works.
