Purpose. Research and analysis of opportunities to improve the quality of insulation from secondary raw materials to study the prospects of their use in the construction industry as innovative materials with better performance than traditional ones. Materials made from secondary raw materials are of great importance not only in the formation of the building materials market, but also in the Ukrainian economy. The processing infrastructure creates a large number of jobs and tax deductions to the budget. In addition, the consumption of energy resources and the cost of servicing energy mains directly depend on the improvement of the thermal efficiency of premises and structures. The use of modern technologies of building materials combines economy, efficiency and durability of structures. Methodology. An important role in the development of modern construction production is played by the possibility of developing and improving the quality of building materials and technologies for their use. In modern conditions of the market of construction products there is an urgent need for constant modernization of construction processes, due to the efficient use of raw materials and the latest processing methods. With the use of modern information technologies and theoretical and methodological ways to solve problems, it becomes possible to consider options for improving the characteristics of building materials by combining qualitative characteristics and eliminating negative ones. Findings. This paper presents scientifically sound methods of modernization of secondary raw materials in the composition of insulation materials with high thermal and economic characteristics, which are able to compete in the market with traditional building materials. The analysis of flame retardants was carried out. Originality. Theoretical and methodological directions have been formed on the basis of research on the use of secondary raw materials for the manufacture of insulation in construction. The comparative characteristic is carried out. The conclusion on the competitiveness of the presented materials in the market of construction materials is made. Practical value. Analysis of the application of modern technologies for recycling on the basis of the latest theoretical and practical approaches, with the subsequent elimination of shortcomings. Consideration of the possibility of adding flame retardants to the composition of materials. Use of materials as insulation of premises and buildings. Development of processing infrastructure of Ukraine.
Problem statement. The introduction of new requirements for rationing in the construction industry provides for changes in the rationing methodology, through the use of a predominantly parametric method. This stimulates the use in management of modern approaches, methods and mechanisms, technologies, innovative organizational and technological solutions to improve the quality and volume of construction, which in turn can accelerate the recovery from the crisis and the development of the construction industry as a whole.The use of the parametric method, in addition to the certain advantages indicated above, creates new challenges for the efficiency of management in the construction industry. On the one hand, there is an increase in the alternatives of possible managerial and organizational and technological solutions; identification of the list and consequences of risks for each alternative; improvement of the procedure and processes for predicting the consequences of each of the alternatives; putting forward new requirements for the information necessary for decision-making, the possibilities of its analysis and interpretation.On the other hand, the use of such a selection mechanism and the lack of clear requirements and orders can increase the costs of achieving the declared quality and reliability requirements of the construction object, and accordingly increase financial and organizational and technological risks. This creates the preconditions for the use of integrated management with the use of appropriate organizational and technological solutions that can satisfy both the requirements of quality management and risk management in construction. Purpose of the article − describe and substantiate the possibility of applying the mechanism for choosing organizational and technological solutions aimed at achieving parametric criteria as target indicators for managing construction processes in conditions of uncertainty using a functional model of a system-integrated approach. Conclusion. It has been substantiated that for an effective process of managing construction processes within an integrated approach, in conditions of uncertainty, it is necessary to use a system-wide algorithmic mechanism, which will ensure the coordination of control functions, their parallel and continuous execution within individual processes, the choice and decision-making in emergency situations for a minimum possible time period.This requires the compliance of each organizational and technological solution with the established criteria and the possibility of their comparison, in order to select the most effective in terms of leveling risk, achieving efficiency − in relation to their cost; and criteria for feasibility, assessment of the impact on quality indicators, implementation in time, competence and technological feasibility − in relation to their ability to implement. Keywords: construction process management; rationing; parametric method, integrated approach; processapproach; situational approach; a mechanism for choosing organizational and technological solutions
Purpose. Justification of the appropriateness of use in terms of efficiency for a construction company, the process of integrating quality management and risk management. Determination of the principles of applying an integrative management model, modules for managing the quality of construction in conditions of risks based on a dynamic system. Methodology. Analysis and generalization of scientific research, practical approaches to quality management and risk management of construction projects, the use of the integration method and the method of identification of QM and RM processes, which makes it possible to substantiate the possibility of developing an integrated approach and determine the principles of applying an integrated quality management model in the face of risks. Results. The study substantiated the feasibility of using an integrative model of risk and quality management in construction, which allows the QM and RM processes to be aligned with the project efficiency criteria, and makes it possible to eliminate contradictions between the quality requirements for the construction object and the level of acceptable risks, and also aligns them with the efficiency requirements for developer. Originality. The principles of quality and risk management are determined, which are prerequisites for the integration of QM and RM processes; modules and levels of implementation of an integrated model of quality management in a risk environment, taking into account the requirements of project efficiency. Practical value. The use of an integrated approach aimed at combining quality management modules for projects and risks in the construction industry will allow to level all the contradictions of these processes in practical implementation, to harmonize with the efficiency requirements for projects and balance the costs of ensuring the planned quality level, provided that the acceptable level of risks is observed.
