|Title||Labor productivity measurement in building projects|
The aim of this paper is to report on measuring labor productivity for block works on building projects in the Gaza Strip by using activity sampling for block works. The labor productivity measurement on construction sites was based on studying block work in the Gaza Strip. In this research activity sampling technique has been chosen. Data for this study was collected from construction sites of sheikh Zayed township project through observations. This township project includes 70 five-story buildings, 5 twelvestory buildings, a mosque, a school, shops, offices, and two water reservoirs. It includes also the construction of infrastructure works. The results indicate that the average productivity rate of skilled labor in laying blocks 20 is 38.40 blocks per hour (3.07 m2/h), while average productivity rate of skilled labor in laying block 10 is 40.50 blocks per hour (3.24 m2/h). The research looked at the distributions of skilled labor time and unskilled labor time in working day. The finding also indicate that productive time of skilled labor was 77% of his working time, while productive time of unskilled labor was 9.34% of his working time. It is hoped that this research will lead to an improvement of the construction productivity in Palestine and other developing countries..
