  • Over the decades, worker performance on construction projects has been a significant source of concern to be evaluated. Comprehensive studies have developed models for evaluating worker performance outside of the construction industry; however, minimal research has been conducted to evaluate worker performance in the construction industry. One of the reasons for a lack of similar research in construction is because the construction process makes construction more complicated compared to other industries. This research aims to further develop a new way of evaluating worker performance in the construction industry using the energy concept. Within the context of this research, “energy” is a property related to performing construction operations and can be defined as the feeling of stress, pressure, and being overwhelmed as a result of the factors, conditions, and resources that accompany the performance of the task. To develop the energy model, an initial conceptual model from previous research and literature review was used as a starting point. The conceptual model contained three levels (constituents, components, and metrics) to measure the level of energy felt by a worker when performing construction operations. The Delphi method was utilized to identify, verify, and quantify the constituents and components, and confirm the energy model. The results from the literature review and Delphi survey revealed 14 constituents, 53 components, and one metric for each component to measure the level of energy. Constituents, components, and metrics were used to develop the energy model to evaluate worker performance on construction sites during a project and assess an ongoing project. The contributions of this research to knowledge are the validation and identification of the constituents, components, and metrics used for evaluating worker performance using the energy concept. The energy model contributes to evaluating worker performance in the construction industry based on the level of energy felt by the worker.
