“…additional 15 and 20 minute breaks for temperature rehabilitation due to the limit values of weather hardness and the creation of appropriate rehabilitation procedure. The model also calculates the probability [17][18][19] of absenteeism due to diseases associated with severe weather. Figure 3 shows the dependence of the possible values of injuries of construction workers due to the severity of the weather.…”

This study investigates the influence of climatic conditions on the performance of the construction process and the characteristics of the elements of the construction process: construction machines, workers, the estimated cost of construction, and the reliability of construction deadlines. As an integral indicator of weather and climatic conditions, the indicator of “weather hardness” was chosen. The method of simulation modeling with its ability to generate random numbers with the given parameters is chosen as a mathematical model on a computer. The aim of the study is to identify the regression and correlation relationships between the indicators of weather hardness and the corresponding indicators of the elements of the construction process: the Fund for working time of workers, the coefficient of technical readiness of construction equipment, increasing the estimated cost of construction, increasing labor costs for the re-installation of construction equipment, identification of additional costs by types of work, for all the stated dependencies, regression equations are obtained. The results are presented in graphical form, and the results show that the proposed simulation model of the impact of weather and climatic conditions on the characteristics of the construction process allows to optimize management decisions, and reduce construction risks, reduce the estimated cost of construction.

“…As a result, some financial institutions and investors do not invest in construction projects, explaining their actions are due to increased level of risk in construction industry. [6][7][8][9] According to the ISO 31000 international risk management standard in construction projects, risk can be defined as the probability of an event that impairs the viability of a project [10] Not all risks should be associated with negative results, because, although in most cases this happens, risks can also mean potential opportunities. From the time the project objectives are set, construction time, cost, and quality are the most important risk factors to consider.…”

This study focuses on enhancing the effectiveness of investment in construction given the constant threat of new risks. We investigate the types and causes of risks of firms working in the construction industry, draw conclusions about the importance of risks associated with the investment attractiveness of projects, as well as responsibility for the environmental safety. Urbanization and changes in the surrounding area are the dominant trend in the development of modern society. The constant demand of business for commercial real estate, as well as the increase in population growth demands enhanced effectiveness in the construction market, where supply in construction market depends on the economic conditions. The relevance of the research topic is due to the fact that the increasing capital flows in the construction industry pose new challenges for forecasting, statistics and risk control, and a focus on the rates of return mechanisms to hedge against the uncertainty of the future. The aim of the study is a systematic integrated approach to solving problems to improve the efficiency and effectiveness of investments and their protection using a methodological systematic approach, which considers the components of an integrated investment process. We propose a model of risk hedging management, and focus on an analytical methodology of the most relevant risks in modern construction.

“…In these methods the estimated effects of the event and the probability or frequency of occurrence of certain effects are attributed to conventional qualities characterizing their value. The assigned qualities can be descriptive or measured by the quality of something rather than its quantity [21]. The choice of the methods depends on the type of the assessed work process, the type of hazards, and availability of data.…”

Working at height, and especially on construction scaffolding, is one of the most accident-prone situations on a construction site. The article attempts to assess the state of threat of working on scaffolding on the basis of the proposed coefficients concerning the possibility of an occupational accident occurring. The article presents the analysis of 10 parameters, which were classified into three groups of factors that cause accidents: technical, organizational, and human factors. In order to assess the state of threat of working on scaffolding, partial hazard factors and a simplified and accurate factor of the state of threat of working were proposed. The coefficients were determined on the basis of the data collected from post-accidental control reports on occupational accidents occurring on scaffolding in the construction industry that took place in Poland in five voivodeships in the years 2008–2017, and also on the basis of the obtained results of research on 120 scaffoldings conducted in the years 2016–2018. Based on the determined factors, it was possible to determine the probability of an undesirable event, in other words, an occupational accident. In addition, the developed test method proposed numerical scales for assessing the state of threat of working on scaffolding. The form proposed in the article for assessing the state of threat of working on scaffolding, which was developed using a spreadsheet, can provide support for people managing work at workstations involving scaffolding, for example, construction directors, construction engineers, work managers, or construction managers.
