Weather affects building construction in many different ways. High temperatures can cause crew health problems due to lack of hydration, sun burn, and heat exhaustion. Low temperatures lead to frost bite and low core temperatures not to mention more clothing that slows the workers’ pace. Precipitation in the form of rain is dangerous around power tools and zaps the body of its heat and if it is snow, clearing the site before and during the day takes time and energy. Ice forming on surfaces also takes its toll on speed and safety. Wind is another factor that may deny the crew from safely standing walls, trusses, or sheeting a roof.
