The adverse impact of the coronavirus (COVID-19) on the health and safety of the construction industry has been studied by many researchers, but few have identified strategies for mitigating its effects and correlated them with the size of an organization. This research aims to identify the precautionary practices implemented by small, medium, and large construction companies and determine how much the size of the company influences the frequency with which they are practiced. To achieve this goal, an extensive literature search was performed and was followed by a questionnaire survey. A total of 63 responses to the survey were received and statistically analyzed, revealing that the most common practices were encouraging sick workers to stay at home, initiating health and safety procedures on job sites, providing paid sick leave, and instructing workers to wear personal protective equipment (PPE). The analysis also found that an organization's size significantly influences how frequently the practices are executed. The study results will assist researchers and professionals in understanding how often the identified precaution practices were implemented by small, medium, and large-scale construction companies during the pandemic and will help them develop similar techniques for future health crises.
