Abstract
In this study the labor productivity (LP) and the effects of main factors on LP in building projects in Sulaimani City practically on field sites were investigated for gypsum plastering (GP) works. Accordingly, the most important effective factors on LP were, height(h), number of skilled laborers (SkL) and Crew size (Cz). 30 practical data on field sites were practically observed.
The results showed that the minimum and maximum LP were between 10.53 and 23.73 m2/hr. The average LP was 15.2 m2/hr., while h=0-3 m, SkL=1-2 laborers and Cz=2-4 laborers. The study investigated that the h, SkL and Cz had a direct effect on LP, while it is found that the age and experience of laborers had a slight effect on LP. A model with a significant relation R 2 97.5% with the factors was found to predict the LP for gypsum plastering
