Activity-Based Construction Labor Productivity in China and the US
This paper investigates the differences of construction labor productivity (CLP) in the United States and China at the activity level in order to have a clear picture of the productivity status of both countries from an operational perspective. Supplementing other comparative construction studies measuring productivity by out value per person, this research examined the CLPs, measured by physical quantity per labor hour, on major building projects. Selected sample activities include earthwork, concrete, masonry, structural steel, water proofing and interior finishes. Paired comparisons (US-China) of these selected activities were then analyzed and evaluated. The data source of US labor productivity was RS Mean’s Cost Data, which was cross-validated by data from Walker’s Building Estimator’s Reference Book. The data source of Chinese labor productivity was mainly the Beijing Construction Quota, which was cross-validated by Chinese quotas from several other cities and provinces in China. In terms of hourly output, significant differences were observed in many operational categories. It appears that Chinese CLP significantly lag behind its US counterpart for equipment intensive construction activities. Smaller CLP gaps or comparable CLPs between the two countries were observed for labor intensive activities. Based on these findings, construction equipment efficiency appears to be a major contributing factor to the productivity difference between the two countries.
