Climatic effects on construction

The results of an investigation designed to determine the relationship between overall construction productivity, and temperature and humidity are presented. Data from the following activities or crafts, or both, were employed: excavation (manual), erection, masonry, electrical, carpentry, laborers, and excavation (equipment). Two nonlinear equations were determined, one for cold or cool weather (R2 = 0.62) and another for hot or warm weather (R2 = 0.64). The overall findings indicate that below –10° F and above 110° F it is difficult to achieve efficient construction operations. In addition to productivity data, the health hazards, possible preventive measures, and acclimatization of workers to severe environments are examined.
