Abstract or Summary
  • Over the years, the performance of construction projects has been a main source of concern given the percentage of a project cost associated with poor project performance. As a result of the growing clamor to improve the output of the built industry, comprehensive studies have been conducted to examine the factors that affect construction productivity, cost, schedule, safety and quality. However, little has been done to quantify the cumulative effect of project characteristics on the construction workforce. This study adopts the physical property of energy as a means to understand and quantify impacts to worker performance. To conduct the study, energy and its derivatives (power and pressure) were first translated from their physical sense to the context of work operations on a construction site. Once defined for construction operations, the research included conducting a survey of construction workers across 3 construction projects in the Pacific Northwest to quantify the workforce's perspective of construction energy and how work-related energy components impact construction workers. Specifically, the survey measured the impact of 55 components that were identified through an extensive literature search as possible constituents of energy. Craft workers, foremen, superintendents, project engineers, project managers, safety professionals, and owner representatives provided detailed insight into the energy components affecting their safety and quality of their daily output. The survey was followed by a severity analysis to determine the key components that play a major role in determining construction project performance. Analysis of the feedback from participants shows that while each work level rated the components differently, attitude of worker to safety and the use of poor quality materials were rated as the most impactful factors to safety and quality of work on a project level, respectively. Using these components, a project management framework for forecasting and evaluating safety and quality performance on a construction project utilizing energy principles as its foundation was developed and proposed. The framework may be used to plan the construction operations for optimal safety and quality.
