When designing external façade claddings, civil engineers consider a variety of factors such as the building’s location, climate, and intended use. They also consider the building’s structural requirements, as well as codes and regulations related to fire safety and energy efficiency. They will also consider the aesthetic and architectural design of the building, as well as the materials that will be used for the cladding. They will also consider the cost of materials and construction, and how the cladding will be installed and maintained over time. The final design will be tested to ensure that the cladding will be able to withstand wind, rain, and other environmental factors, and that it will last for many years without requiring major repairs or replacement.
