Abstract
This paper describes the assessment of the probabilistic risk of an accident formed in the process of designing a technically complex facility. It considers values of conditional probabilities of the compliance of load-bearing structures with safety requirements, provides an approximate list of significant errors of the designer and analyzes the relationship between the degree of compliance and the level of danger of errors. It describes and proposes for implementation the regulated procedures related to the assessment of the safety level of constructive solutions and the reliability of the construction process participants.
Highlights
High-rise multi-profile buildings should be classified as technically complex construction projects
For a complex construction facility, safety must be ensured by the reliability of engineering systems and equipment
It is possible to manage the risk of erecting and operating a technically complex facility on the basis of the development and implementation of regulated procedures related to the assessment of the safety level of constructive solutions and the reliability of both engineering systems and all construction process participants
Summary
High-rise multi-profile buildings should be classified as technically complex construction projects. The reliability of load-bearing structures is the main indicator ensuring safety of operation at any stage of the life cycle for the construction facility. For a complex construction facility, safety must be ensured by the reliability of engineering systems and equipment. It is necessary to solve the problems of ensuring reliability of both the structural part and the operation of the building, strive to reduce the material consumption, optimize the ventilation and hydraulic regime, and the energy consumption regime at the design stage of a complex facility. It is possible to manage the risk of erecting and operating a technically complex facility on the basis of the development and implementation of regulated procedures related to the assessment of the safety level of constructive solutions and the reliability of both engineering systems and all construction process participants
