Purpose: An analysis is presented of the use of material and construction solutions used in construction, mainly residential, for the construction of OC (civil defence) shelters. Design/methodology/approach: The article presents procedures for designing reinforced concrete structures that make it possible to properly determine the load capacity of critical sections. In the present work, a study of the deformation stability of a zone of reinforced concrete sections that is subjected to compression is used. Computational methods based on Drucker's postulate were used to solve the problem. The proposed approach enables the determination of the values of ultimate and failure strains based on the analysis of the loading path of a reinforced concrete section. Findings: Generally, shelters built into residential buildings are analysed, intended to be constructed in the rooms of the basement floor. A reduced need for ancillary space, the basement room, is observed. Garage functions are located on the basement floor. The plan contours of the basement are often larger than those of the ground floor. It is possible to design a shelter for the residents of the building, which ensures the greatest efficiency in its use. It is desirable to maintain uniform material and construction solutions while maintaining technological and organisational solutions during the erection of the entire building. Research limitations/implications: The paper indicates the possibility of using some of the material and structural solutions of the housing construction in the realisation of OC shelters built into the basement floor. The construction of free-standing shelters was not analysed separately, but the proposals presented in the paper can also be applied to the type of OC shelters. Some results of the analysis of the adaptation of material and structural solutions of the housing construction to the needs of OC shelters construction will be presented during the symposium. Practical implications: It is advisable to develop models for the construction of OC shelters using contemporary technologies used in the construction industry. Originality/value: Useful tool can be the proposed scheme for improving activities based on the EFQM model.

Construction objects arise during the implementation of construction projects. Participants in these projects are interested in taking systematic actions to improve the state of occupational safety and health protection. The effectiveness of these activities requires that they be carried out as part of a comprehensive system of managing the construction project implementation process. The safety management and health protection system is part of the overall project management system, which includes: organizational structure, planning, responsibility, rules of conduct, procedures, processes and resources and requires analysis of safety and health protection issues in its individual areas, phases and stages. This is primarily due to the fact that proper management is the most effective way to ensure an adequate level of safety and health protection (S&HP), desirable both due to the need to comply with legal provisions in force in construction, social expectations, and the possibility of obtaining positive economic effects by individual process participants in the scale of the entire construction project. The article proposes a theoretical model of the built undertaking that can be used to recognize the state of bioses. The model distinguishes parts, activities and areas in accordance with the logical course of the process, which was assigned to individual stages of the project. A research tool - RADAR S&HP - was developed to identify the factors affecting S&HP. To assess the condition of bioses, an analytical and mathematical model of the examined undertaking was formulated to ultimately determine the directions of preventive actions in the field of safety and health protection at individual stages, phases and areas of the construction project implementation process.

Bezpieczeństwo i ochrona zdrowia w pracy podczas realizacji procesów inwestycyjnych w budownictwie nabiera coraz większego znaczenia. Procesy, podczas których powstają obiekty budowlane charakteryzują się wysokim poziomem zagrożeń dla zdrowia i życia uczestników biorących udział w realizacji przedsięwzięcia budowlanego. Zagrożenia te są skutkiem niewłaściwego projektowania, realizacji obiektu budowlanego i jego użytkowania, warunków pracy, dużą zmiennością warunków atmosferycznych oraz zachowań pracowników wynikających z obowiązujących wymagań prawa, zasad i kultury bezpieczeństwa pracy lub pominięcia zagadnień szeroko pojętego bezpieczeństwa związanego z obiektem. W artykule przedstawiono znaczenie etyki zawodowej w zapewnianiu i utrzymaniu właściwego poziomu bezpieczeństwa i ochrony zdrowia w życiu obiektu budowlanego.

Safety and health protection at work during the implementation of investment processes in construction is becoming increasingly important. The processes during which construction works are created are characterized by a high level of threats to the health and life of participants taking part in the implementation of a construction project. These hazards are the result of improperdesign, construction of the building and its use, working conditions, high variability of weather conditions and employee behavior resulting from applicable legal requirements, principles and culture of work safety or omission of broadly understood security issues related to the object. The article presents the importance of professional ethics in ensuring and maintaining an appropriate level of safety and health in the life of a building.
