Problem statement. The need for the formation and development of human resources in the construction industry of Ukraine to create a competitive sphere that complies with high standards of quality and efficiency, operating based on modern financial, economic, technical, and organizational mechanisms. One method to achieve the goals of innovative development is the modernization of architectural and construction design and engineering networks, particularly through the implementation of Building Information Modeling (BIM) technologies. These technologies enable effective decision-making at all stages of the life cycle of buildings and structures − from the initial idea to the stage of operation and even the dismantling of water supply and wastewater system engineering networks. The purpose of the article − to explore the utilization of BIM technologies to enhance the efficiency and accuracy of designing water supply and wastewater systems Conclusions. The application of BIM technologies in the design of water supply and wastewater systems significantly improves work efficiency. Creating digital models facilitates the interaction of all participants in the construction process and minimizes errors and conflicts during the design phase. The success of modernizing the construction industry became possible through active collaboration of all stakeholders. Public advocacy and participation in addressing industry issues provided a broader perspective on problem-solving. The implementation of BIM technologies allows for the development and improvement of water supply and wastewater system projects, contributing to work optimization and project planning enhancement.

Modern society faces a complex of problems related to the effective use of information. The combination of document studies with theoretical and applied management tasks makes it possible to talk about the existence of a separate document category that provides management processes. Documents are the basis for making and implementing management decisions and at the same time are their reflection. The level of management documentation, or record keeping, is an important factor in the effectiveness of any enterprise, institution, or organization. Management documentation covers several documentation systems. They, solving general issues, reflect the regularities and peculiarities of one or another sphere of activity. One of such systems is personnel documentation. Highlighting the specifics of personnel administration is important for understanding its place in the management system. In this connection, the problem arises of determining the personnel documentation role in the management processes of the organization, its analysis from the point of view of the performed functions. The study of personnel records as a separate subsystem in the documentation support of management processes is the basis of this work. The relevance of the problems discussed in the work is due to the modern development of Ukraine’s economy. Objectively, personnel administration acts as a mediator between two areas that do not entirely coincide: between labor legislation and the personnel management system. Today, issues of organizing an effective system of work with personnel at enterprises, institutions and organizations are becoming more and more important. In this regard, the role of personnel administration is growing, and the analysis and improvement of the work organization for the personnel service is gaining special relevance.

Problem statement. The present-day realities show that the design of buildings and structures with regard to possible local collapses of their bearing structures is becoming more and more realistic and thus an increasingly urgent challenge. The need to solve this issue is an important component in ensuring the safety of buildings and structures under operational and emergency loads. Local destruction is interpreted as a global result that can lead to the destruction of the entire frame or a significant part of it and cause loss of life. The peculiarity of calculations for progressive collapse of steel-framed buildings is that, unlike monolithic reinforced concrete, in a steel frame, the nodes of connection of elements are usually hinged, and this can lead to transformation of the structural scheme into a geometrically variable structural scheme. In this case, structural failure may occur not due to loss of material strength, but due to loss of load-bearing capacity of the structural connection joints. The purpose of the article is to analyse the main specific peculiarities occurring in the design (reinforcement) of industrial buildings with steel frames, considering the possibility of their local destruction. Conclusion. The article considers some problems that need to be solved during the designing or reconstructioning industrial buildings with a steel frame, the operation of which may be associated with some local destruction of the bearing structures. Prospective constructive ways of effectively solving these problems are presented.

Problem statement. The design of wastewater treatment systems is a complex process and requires the use of special mathematical models. As a rule, empirical models are used at the stage of designing structures of water drainage systems, which allow obtaining only an “integral” characteristic of the efficiency of wastewater treatment. But in a number of cases, it is important to have information about the spatial distribution of the impurity concentration in the structure. To solve this problem, you need to have three-dimensional mathematical models. In the future, there is a shortage of such models, so the creation of three-dimensional multifactorial models for the analysis of the efficiency of drainage system structures is an urgent task. The purpose of the article. Development of a three-dimensional numerical model for the analysis of the mass transfer process to determine the impurity concentration in the clarifier. Methodology. The analysis of impurity concentration fields in the clarifier is carried out by numerical integration of the three-dimensional equation for the velocity potential and the three-dimensional equation of the convective-diffusion transport of the impurity. For the numerical integration of the Laplace equation for the velocity potential, the variable-triangular method and the Liebmann method are used. Finite-difference splitting schemes are used for numerical integration of the three-dimensional equation of convective-diffusion transport of impurities. Scientific novelty. A dynamic multifactorial numerical model was created for the analysis of the process of mass transfer of impurities in a settling tank by conducting a computational experiment. Practical value. The built multifactorial numerical model makes it possible to analyze the efficiency of wastewater treatment in clarifiers that have a complex geometric shape and cannot be calculated on the basis of existing engineering methods. Conclusions. On the basis of the developed three-dimensional numerical model, a computer code was created, which allows you to quickly obtain information about the distribution of the impurity concentration in the settling tank.

Problem statement. In Ukraine, green energy, in particular, solar power plants, is developing rapidly in recent years. Their power depends on the area of solar panels, so large land plots are required for powerful plants. In the context of urban development, there are almost no free plots. It is proposed to place such stations on the roofs of residential buildings. The problem is that in order to implement this, it is necessary to investigate the technical condition of the roof structures. To do this, it is necessary to develop technique for surveying the roofs’ technical state. The purpose of the work is to classify the survey objects, with further development of the visual observation methodology, instrumental measurements, selection of facts, and establishment of links between them. Method. The methods of visual observation, instrumental measurements, data accumulation, selection of facts, and establishing links between them were used to develop the classification of the survey objects. The types of residential buildings that were built from the 30s to the 80s of the last century on the territory of Ukraine were studied. The investigation of urban residential buildings for the purpose of their classification was conducted according to consumer and operational characteristics. The result of the research is the development of a technique for the application of research methods such as visual inspection, instrumental measurements. A technique for surveying the technical state of those types of roofs that were included in the classification based on the study of existing residential buildings was developed. The scientific novelty is that the technique is developing for the first time for surveying the technical state of roofs and garrets, for the tasks of placing electric solar stations on their surface. Practical value. With the help of the developed technique, it will be possible to conduct a survey of the technical condition of roofs and garrets for the placement of solar stations on their surface by all organisations that are engaged in such work and have the necessary experience and tools. Conclusions. A classification of types of roofs and garrets of residential buildings was developed for the possible location of electric solar batteries on their surface, as well as a technique for surveying the technical state of roofs and garrets structures was developed.

Problem statement. Electromagnetic radiation is a combination of electric and magnetic radiation, the energy of which, when it affects a given material body, does not cause an ionisation process in it. Natural electromagnetic radiation not only guarantees the proper development of every living organism, but also affects the change of seasons and weather. Humans have disturbed the Earth's natural electromagnetic environment by including devices that emit electromagnetic energy in a wide range of frequencies. Artificial electromagnetic fields accompany us everywhere: at home, at work, on the road, and during leisure. The sanitary and hygienic state of the environment, including the electromagnetic situation in populated cities, is of great hygienic importance for ensuring proper living conditions for the population. The electromagnetic situation in cities and other settlements is created by a large number of radio and electrical equipment for economic, defence and other purposes. The purpose of the article. To conduct a systematic analysis of the impact of electromagnetic radiation from various types of electrical equipment on the environment. It is shown that electromagnetic radiation is dangerous both for the population as a whole, especially for children, and for personnel who operate powerful equipment - sources of electromagnetic radiation. Conclusion. Studies of electromagnetic radiation in the environment show that prolonged exposure to powerful electromagnetic fields can cause illness and even death. Therefore, rules for using artificial sources of electromagnetic radiation should be followed to minimise the damage to both human health and the environment. These rules are not so difficult to follow, but they are quite effective. And for labour protection and civil safety specialists, this knowledge will enable them to create safe working conditions in the workplace.

Problem statement. The issue of studying the working conditions of workers with increased heat exposure is considered. Diseases provoked by harmful working conditions have a rather long incubation period, so their manifestation is not always easy to recognize and there are difficulties in establishing the root cause of occupational disease. The purpose of the article. Development and implementation of risk assessment methodology based on the joint action of harmful and hazardous industrial factors and regularities of their intensity decrease with distance from the source. Methodology. The impact of occupational and heterogeneous industrial factors on the employee's health, taking into account the time of action and the impact of their joint action in quantitative form, can be fairly objectively assessed on the basis of the Weber-Fechner law through the calculation of the integral index of potential risk. Structural analysis was used to determine the structure and causes of occupational diseases. Correlation analysis was carried out to find out the nature of relationships between the levels of influence of factors of the industrial environment to assess the conditions and nature of labor at the workplaces of workers, at whose workplaces the increased thermal stress was installed. Probabilistic-statistical methods were used for data processing - to determine the algorithm of transformation of environmental parameters into an indicator of occupational risk for workers with harmful working conditions. Development of a model for determining the zones of transformation of occupational risk through mutual influence on the industrial risk of the processing of research results needed the application of formalization methods. A software system for the formation of aggregated for multivariate analysis of information was used, which made it possible to build a three-dimensional model of changes in the values of the indicator of occupational risk in the space between the workplaces of employees located in the welding department. Scientific novelty. The applied risk-oriented approach using the methods of occupational and industrial risk assessment for electric welders' workplaces allows to take into account the harm to the worker's organism from the factors of the industrial environment. The established regularities allow to determine the zones of transformation of occupational risk through mutual influence into production risk, which is the justification of measures to reduce injuries and occupational diseases. Practical value. On the example of labor conditions at the workplaces of electric welders the methodology of risk assessment is developed and tested taking into account the joint action of harmful and hazardous industrial factors and regularities of their intensity decrease with distance from the source. The given risk-oriented approach allows to fulfill all the requirements and recommendations set forth in ISO 45001: its application to the working con

A software system for the formation of aggregated for multivariate analysis of information was used, which made it possible to build a three-dimensional model of changes in the values of the indicator of occupational risk in the space between the workplaces of employees located in the welding department. Scientific novelty. The applied risk-oriented approach using the methods of occupational and industrial risk assessment for electric welders' workplaces allows to take into account the harm to the worker's organism from the factors of the industrial environment. The established regularities allow to determine the zones of transformation of occupational risk through mutual influence into production risk, which is the justification of measures to reduce injuries and occupational diseases. Practical value. On the example of labor conditions at the workplaces of electric welders the methodology of risk assessment is developed and tested taking into account the joint action of harmful and hazardous industrial factors and regularities of their intensity decrease with distance from the source. The given risk-oriented approach allows to fulfill all the requirements and recommendations set forth in ISO 45001: its application to the working con","PeriodicalId":228894,"journal":{"name":"Ukrainian Journal of Civil Engineering and Architecture","volume":"101 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140680023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The considers the field of development, specifically focusing on the organization of project management in development. It is demonstrated that real estate development possesses certain characteristics that directly impact the activities of developers and the organization of development management. The presence of these characteristics creates a unique environment in which developers operate, influencing various approaches, schemes, forms, and models of project development management organization. The purpose of the article is to formulate systematic concepts regarding the forms of organization in development projects. To achieve the goal of forming a comprehensive understanding of organizational mechanisms for managing development projects, the paper examines the organizational environment in which project teams operate and the forms of project management organization in development companies. The paper illustrates that in the project life cycle model, the organizational structure of project management can vary both within individual phases and across projects of different concepts and scales. The management organization during different phases of the project life cycle (PLC) and the organizational structures of development companies during the construction phase have been analyzed. It is demonstrated that contemporary organizations consistently channel their efforts towards improving (developing) the organizational management environment in development and creating conditions for the successful implementation of projects. Therefore, in addition to the value of creating new tangible assets, the project management group (PMG) adds (creates) value through the establishment of a unique organizational environment. The approach to evaluating the values of collaborative work within a project team is demonstrated. The developed organizational environment unquestionably represents a value that the developer additionally acquires along with new development projects. Task: the paper explores the organization of project management groups (PMG) in development; organizational forms of development project management; the organization of project management in development during the construction phase as the most significant; and organizational structures of development companies. Research results: a system application for the organization of development projects’ management has been created. Possible forms of development projects’ organization and elements of the company's organizational structure are analyzed.

Problem statement. Under the influence of European integration, globalisation and with the aim of building a single European higher education area, an important task for Ukrainian educators is to study the practical experience of foreign colleagues, in particular, in improving the pedagogical competence of teachers in higher technical education institutions. This study aims to investigate the issue of improving the pedagogical competence of teachers at the TU Bergakademie Freiberg (where one of the authors is studying under a double degree programme). Given the high standards set by German society for teachers responsible for training young professionals, we consider it necessary to analyse in detail the features of the current system of teacher training in Germany in order to be able to improve the Ukrainian system of training/retraining of scientific and pedagogical staff for higher technical education institutions. The purpose of the article is to investigate the professional development path that German teachers go through; and to analyse the innovative methods and programmes that help them become not only specialists in their field, but also effective teachers. Through this research, we aim to contribute to the understanding of the education process in Germany and to identify practices that may be useful in the context of improving higher education in Ukraine. Conclusions. The developed German system of retraining and professional up-skilling of pedagogical staff (represented by state academies/in-service training institutes and special centres of teacher education within universities) is aimed at comprehensive support of teaching staff for their continuous professional growth as civil servants responsible for the quality training of young professionals for the needs of the leading EU state. It is important to note the urgent need to use the achievements of German experience in practical training and professional up-skilling of teachers in the Ukrainian system of training and retraining of pedagogical and scientific-pedagogical staff in the field of professional pre-university and higher education. The analysis of the process of improving the pedagogical competence of teachers at the TU Bergakademie Freiberg gives grounds to assert that this task is key to ensuring quality education in higher education institutions. It is worth emphasising that the TU Bergakademie Freiberg actively invests in programmes for the professional development of its teachers. These programmes cover various aspects, ranging from technical updates to pedagogical innovations. The combination of professional up-skilling courses for teachers and supervision of students' internships is a clear indication of the dual form of education that is well organised in German society and is currently being actively implemented in Ukraine.

Problem statement. The research demonstrates that existing methods for determining the distribution of thermal radiation intensity using nomograms and formulas contain significant errors. This is due to the adoption of a number of simplifications regarding numerous interdependent parameters, including the temperature inside furnaces, the size of openings and shafts, etc. As a result, there is a need for measurements of thermal radiation intensity at distances of 5−10 meters and beyond. The purpose of the article. The objective of the article is to propose a concept for a new experimental methodology to investigate the intensity of radiation exposure to workers at their workplaces. Simultaneously, in order to address the issues of thermal protection for workers, actual measurement data of thermal radiation levels are necessary for each workstation under real working conditions within the workspace. Conclusion. It is important to characterize the composition of the gas environment, as its impurities can distort the distribution of radiant energy through interference and diffraction effects, which need to be considered for microclimate optimization. The presence of dust particles complicates the straight-line heat transfer through scattering and scintillation of rays, requiring further improvement of models. Turbulence, impurities, and atmospheric heterogeneity are important factors that need to be further investigated and taken into account in heat transfer process modeling. Scintillation affects the quality of radiation transmission, necessitating further study of this phenomenon. Local atmospheric composition peculiarities require the development of models that consider these variations. The obtained experimental data will contribute to improving the accuracy of modeling and enhancing working conditions. Further refinement of measurement techniques is necessary for obtaining reliable information.
