General Circulation Models (GCMs) are sophisticated tools used primarily in meteorology and climate science to simulate the Earth’s climate system by mathematically representing the physical processes that govern atmospheric and oceanic circulation. In the context of the construction industry, understanding GCMs can play a vital role in ensuring safety and risk management, particularly because construction activities are highly dependent on weather conditions and long-term climate patterns. Construction sites are exposed to numerous environmental hazards such as storms, heavy rainfall, heatwaves, and high winds, all of which can be better anticipated and managed with insights from GCMs. GCMs provide projections of temperature, precipitation, wind patterns, and extreme weather events, enabling construction managers to plan for and mitigate risks associated with these variables. By integrating GCM-based forecasts into project planning, construction companies can adopt preventive measures, reduce accidents, and protect workers’ health. GCMs operate by dividing the Earth into a three-dimensional grid system, where each grid cell represents a specific volume of the atmosphere or ocean. Physical laws, such as the conservation of momentum, energy, and mass, are applied to these cells, allowing the models to simulate atmospheric dynamics, ocean currents, and interactions between different climate components. These models incorporate a wide array of variables, including solar radiation, greenhouse gas concentrations, cloud cover, humidity, and land surface properties. For construction safety, this information is invaluable because it allows project planners to anticipate adverse weather conditions that could compromise structural integrity, equipment safety, or
