Statistical Analysis of the Effectiveness of Management Programs in Improving Construction Labor Productivity on Large Industrial Projects

Abstract

AbstractThe purpose of this research effort is to identify the effectiveness of a particular set of important management programs in improving construction labor productivity. These programs were previously defined through industry experts and research consensus as having significant impact on project cost, schedule, safety, scope, and quality performance, but their relationship to labor productivity was not known. Through statistical analyses of the database maintained by the Construction Industry Institute’s Benchmarking and Metrics Committee, headquartered in Austin, Texas, United States, the research presented in this article examined whether projects with high levels of implementation of programs related to front-end planning, materials management, automation and integration of information systems, team building, constructability, and safety, experienced better labor productivity among the mechanical, electrical, concrete, and structural steel trades compared to projects with low levels of implementa...
