Construction sites are essentially outdoor factories and are highly influenced by various weather conditions, such as air temperature, humidity, precipitation, pressure, and wind speed. To ensure efficient organization and management of construction sites, it's crucial to consider several parameters, with weather conditions being one of the most significant factors. The Rulebook on the method of carrying out expert construction supervision, the conditions and method of keeping a construction diary, and the content of the final report of the supervising engineer prescribe that data on "weather and other conditions essential for the execution of works" should be entered in the construction diary every day. However, the specific data to be recorded is not strictly defined. Based on our experience, we have identified the essential parameters that need to be monitored, including average monthly temperature and pressure, average monthly air humidity, total monthly precipitation, and average monthly wind speed. We conducted a statistical analysis of publicly available data from the State Hydrometeorological Institute (DHMZ) for a 5-year period (2019-2023) to determine how the weather data affects the coefficient of weather conditions necessary for calculating the final coefficient of optimization of the construction site organization. Furthermore, we considered the impact of the planned/contracted deadline for the execution of the works on the statistical analysis of the data. This was presented in the oscillation/displacement of the average value of the parameter for the entire observed five-year period to the average values of the parameter for a shorter period under the planned/contracted deadline of the works. We conducted four separate statistical analyses of weather parameters for the four largest cities in the Republic of Croatia (Zagreb, Split, Rijeka, Osijek).
