Assessment of technical and economic security risks protection at the stages of the life cycle of real estate objects

Abstract

Introduction. An innovative approach to the sustainable development of real estate objects based on a comprehensive analysis of the requirements of resource conservation, technical and economic protection and safe operation is presented. The shortcomings of the current standards for the design of corrosion protection measures are identified, which do not allow modelling the calculation of the life cycle cost (LC). It is shown that it is necessary to expand the calculation and analytical indicators of the expertise of design solutions in order to prevent negative consequences in case of corrosion failure.

Materials and methods. The object of the study is a regulatory management system for which algorithms for making effective decisions on corrosion protection construction projects are developed. A technique for reserving technical and economic protection based on computational models of quality, reliability and safety of structures and structures is proposed. Functional and temporary redundancy of resistance to aggressive influences is carried out taking into account the requirements for operation and safety of the ISO/TC 267 Facility Management (FM) standard. A holistic perception of the criteria of technical and economic protection is achieved with the help of indicators of the expertise of design solutions and the regulations of the housing and communal services for a given level of corrosion hazard (KI – KV) or protection (ZI – ZIV).

Results. The approbation of the principles and conditions of the regulatory reservation of technical and economic protection measures was carried out by setting direct and inverse survivability tasks. The programme of definitive tests included monitoring, risk diagnostics and management of indicators for calculating the cost of housing and communal services. The risk assessment was carried out on the basis of the HAZOP (Hazard and Operability Study) method. The proposed approach provides a scenario analysis of the possibilities and identification of threats to the use of new materials and technologies in accordance with the provisions of the Lean Six Sigma concept of “lean management”.

Conclusions. The theoretical and experimental substantiation of the principles of the regulatory management system for corrosion protection and survivability of real estate objects contributes to the promotion of digital technologies and platform solutions for technical and economic protection based on target indicators of quality, reliability and safety of structures and structures.
