Construction remains one of the most hazardous industrial sectors due to the combined effects of technical, organizational, environmental, and climatic risk factors.This study aimed to develop and test a dynamic approach to occupational risk assessment in the construction industry, taking into account hazardous occupational factors and extreme climatic conditions, and to analyze associations between occupational environmental indicators and recorded morbidity among workers.The methodology combined occupational hygiene assessment, analysis of recorded morbidity, and correlation, regression, and epidemiological risk analyses.Dynamic occupational risk assessment (DORA) tools, including safety checklists for work at height and outdoor work, were developed and tested to support timely hazard identification under changing working conditions.The results revealed distinct occupational risk profiles at the two pilot enterprises.At Enterprise 1, the most pronounced associations were related to physical workload and microclimatic conditions, including associations of work intensity and air temperature with upper respiratory tract diseases (r = 0.816 and r = 0.818, respectively; p < 0.001).At Enterprise 2, chemical aerosols and dust were predominant, with the strongest association observed between quartz-containing inorganic dust and respiratory diseases (r = 0.970; p < 0.001).The findings support differentiated occupational risk management according to site-specific technological, exposure, and climatic conditions.Integration of occupational exposure monitoring with dynamic risk assessment may provide a practical basis for proactive occupational safety management in construction.
