Risk management to ensure the exploitation reliability of high-rise buildings

Abstract

The paper presents the results of a study of design risks affecting the exploitation reliability of high-rise buildings. The aim of the study was to study and optimize risk management strategies. The relevance of the work is justified by the statistics of recorded violations in the design of high-rise buildings, which affects their quality in the process of exploitation, leading to disastrous consequences. Existing methods of risk assessment take into account natural and man-made hazards. The consequences of risk are human victims. Damage to risk is estimated from material losses. The paper suggests refinement to the methodology for assessing project risks. As a criterion of the consequences of risks, the deviation from the normative technical condition is proposed. As a criterion of damage, the value of operating costs, as well as the amount of costs for eliminating not the consequences of risks, but the costs of eliminating their causes at the design stage are proposed. The risk classification was carried out according to the design stages, according to the source of occurrence. The ranking of risk criteria was proposed to establish the priority of their elimination. The algorithm of risk management proposed by the authors can serve as an addition to existing quality control systems for the stage of designing high-rise buildings.

Modeling the process of choosing energy-saving technologies in the exploitation of transport infrastructure buildings

“…However, multicriteria optimization is very complex and rarely used in practice. A scientific approach based on quantitative decision-making methods makes it possible to improve the quality of decisions made [16,17]. Therefore, the purpose of this study is to develop a decision-making model for choosing the optimal energy-saving technology based on the hierarchy analysis method.…”

Justification of ways to improve environmental safety during the liquidation of buildings in the conditions of dense development

“…The final conceptual model of decision making (Table 1) on the choice of additional protective measure is based on a point estimate of the level of effectiveness of its implementation [22][23][24] and takes into account the degree of reduction of the negative impact of the proposed protective measure, the degree of its influence on the increase in material costs during implementation. The following scale of assessment of the degree of influence of an additional measure on the economic efficiency of works is proposed in the work:…”

Development of building exploitation programs in the concept of energy-sustainable urban development

“…It is assumed that such models should be developed by updating information throughout the life cycle of buildings. At the same time, at present, the most widely used information models are used at the design stage [6], to visualize data about the object, as well as to control project risks [7][8][9][10]. To a lesser extent, they are used at the construction stage and are practically not used for data management during the exploitation phase of the buildings [11][12][13].…”
