Analysis of craft workers' and foremen's perceptions of the factors affecting construction labour productivity

Extensive studies have been conducted to examine the factors affecting construction productivity, but efforts have rarely been made to obtain craft workers' input. A survey was administered to 1996 craft workers throughout the US to quantify the workforce's perspective of construction labour productivity. Specifically, the survey measured the impact of 83 productivity factors, which had been identified through 18 focus group sessions with craft workers and their immediate supervisors on jobsites located throughout the US. Craft workers provide detailed insight into the factors affecting their daily productivity, and most of the adversarial factors affecting construction labour productivity can be addressed by jobsite management teams. The major findings indicated that craft workers and foremen share a general perception of the factors impacting on construction productivity; however, differences do exist. Specifically, foremen reported factors related to project management and engineering drawings having a more severe impact on their productivity compared to craft workers, and craft workers reported factors related to construction materials as having a more severe impact.
