Abstract
This research examines the effect of hot climatic conditions on the productivity of construction workers. The objective is to identify the existence of a robust relationship between variations in temperature and workers' productivity. Although climate is known to influence human activities in many pervasive ways, there is a lack of quantitative and qualitative information on the influence of climatic conditions. The main cause of the lack of reliable information about the effects of hot climate on productivity may be that it is difficult to know whether the effects are due to the climate or simply due to other environmental or organizational factors. In this research, particular consideration was given to isolating the influence of several environmental and organizational factors, by constructing a closed system of data collection. Information related to the work output was collected, on a daily basis, by direct observation methods, from live projects. At the same time, data on climatic variability was based on daily information from meteorological stations in the United Arab Emirates, where the live projects are located. This location was determined by the availability of three identical construction projects executed in hot climatic conditions. The choice made the three live projects a reliable source of data collection. The collected data was analysed statistically by the use of regression analysis. The results of the analysis confirm that workers' productivity is affected by hot climatic conditions. However, the results show that there is no consistent relationship between workers' productivity and temperature. Different construction activities have different levels of sensitivity to hot climate. This sensitivity may well be related to the nature of construction operations and the degree of complication associated with them.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
