SYSTEMATIZATION OF RISKS AT THE STAGE OF DESIGN DOCUMENTATION DEVELOPMENT BASED ON THE CONCEPT OF CASCADING DESIGN RISKS

Abstract

Introduction. The article analyzes the risks that arise in the activities of design organizations at the stage of developing design documentation for construction projects. It was established that the process of developing design documentation is characterized by a high level of uncertainty.

Purpose. The main goal of the study is to systematize the risks of design organizations at the stage of developing design documentation, as well as to substantiate the approach to their analysis through the concept of a cascade of design risks and to identify effective intervention points to limit their spread.

Materials and methods. The research materials include: scientific works of the authors in the field of risk management and project management; regulatory and technical documents regulating the process of developing design documentation for construction projects; results of expert observations and practical experience of design organizations in the construction industry.

The following scientific methods were used in the course of the research: theoretical generalization and systematization (to analyze existing approaches to risk classification in the field of design and to develop the structure of the cascade of design risks); expert evaluation (to identify critical intervention points and mechanisms for mitigating the cascade of risks); logical generalization of results (to formulate the conclusions of the study).

Results. The paper analyzes existing approaches to risk classification in the field of design and identifies their limitations associated with the static nature of risk consideration. The feasibility of transitioning to a dynamic model, within which risks are considered as an interconnected process of their sequential emergence and transformation, is substantiated. The concept of a cascade of design risks, reflecting the logic of their occurrence, is proposed. Risks are systematized according to the levels of cascade emergence: primary risks, risks of design decisions, coordination risks, and change risks. It is established that the most critical stages from the management perspective are the stage of initial data formation and the stage of coordination between project disciplines, where effective mitigation of the risk cascade is possible, while at the later stages of design risk management is predominantly compensatory in nature.

The study proposes the concept of a cascade of design risks as a dynamic model for the systematization of risks in the activities of design organizations. The approach to risk classification has been improved through their structuring according to the levels of cascade distribution.

The results of the study are advisable for application in the activities of design organizations in order to improve the effectiveness of risk management at the stage of design documentation development. The proposed approach makes it possible to improve the quality of design works and optimize design timeframes and resources.
