Abstract. The article considers the environmental economic model of risk management and the costs associated with them. In the field of eco-friendly construction and labor safety, it is customary to allocate occupational hazards and hazards, expressed by quantitative or qualitative parameters of occupational risk. Risk management or environmental risk means the recognition and analysis of risks, the development and implementation of management decisions to reduce the likelihood of adverse situations, as well as the possible reduction of material or other losses. Risk management helps to get out of the zone of uncertainty into a situation with more or less predictable results. The methodology for applying the environmental economic model under consideration is a cyclic order of performing interrelated practical actions known as the Deming-Shewhart cycle, which is inextricably linked to the process approach and the quality management system. Synthesis of the principles of the quality management system and mechanisms for managing environmental risks and costs ensures high adaptability to any external and internal stress situations, reveals professional risks in a timely manner, optimizes processes and, as a result, reduces costs.

Modern economic conditions require construction companies to promptly prevent, identify and manage risks in various areas of their construction activities. As this research shows, many of the best practices of corporate risk management are adopted and applied in large Russian construction companies and in various industries. At the same time, the results of the research demonstrate the possibilities for further development. Key areas of development include: the process of integrating risk management into the development strategy of a construction company, the collection and accumulation of statistical data, interaction between units, the participation and active participation of key stakeholders, and the quality of information on key risks. Risk management is one of the most important functional areas in the methodology of project management in the construction sector. In practice, as a rule, in addition to quantitative risk assessment, qualitative risk assessments in construction is also always utilized. However, the theory of risk management based on qualitative assessments is virtually absent in the Russian practice. This article provides a definition of qualitative risk assessments and complex risks in the construction field. We desceibe the tasks involved in risk management in construction and propose algorithms for solving corresponding problems in the construction field.
