Abstract

Labor productivity is among the most critical factors that heavily impact the achievement of a construction projects. In construction sites, construction techniques, construction organization, human resource management, working conditions and worker personal characteristics have significant effects on the labor productivity. Formwork, among others, is a common task in every construction project. This paper presents the measurement of labor productivity by work sampling method for floor and beam formwork of high-rise buildings in Ho Chi Minh City, Vietnam. The research identifies the proportion of time consumption for effective tasks, supportive tasks, and ineffective tasks of formwork as follows: 32%, 35%, and 33% respectively. In other words, the change in the proportion of ineffective work over periods of time through a working day enables a conclusion that the labor productivity of floor and beam formwork workers begins low, then
