Abstract : In construction projects most of the resources are used in the construction phase. Therefore, the cost and time of
each construction activity are the main determinants of the total project cost and time. In this aspect, for an effective project
management it is crucial to calculate the cost and time of activities accurately. The main data for calculating the time and
accordingly the cost of an activity is the labor productivity rate. Since, labor productivity is affected by many factors; its value
rate varies from region to region. This circumstance, forced academicians and industry participants to measure labor
productivity rates for a specific region. One of the commonly used terms for expressing labor productivity in construction
industry is the man-hour value. This value is simply defined as the time required for a labor to finish unit work amount and is
widely used by planning engineers for cost and time analysis. Although, the Ministry of Environment and Urbanization
publishes every year the man-hour values for many construction activities; it is believed that these values are not appropriate
for all regions in Turkey. In this study it was assumed that labors can better evaluate the time they require to finish unit work
amount compared to on site measurements. In this context, actual man-hour values of specified construction activities were
determined by interviewing 126 labors employed in Antalya, Turkey and compared with those values of the Ministry of
Environment and Urbanization. The results revealed that, there are significant differences between these man-hour values and
for an accurate calculation the values of the Ministry of Environment and Urbanization must be updated for each region in
Turkey.
