Abstract

Construction projects worldwide are significantly affected by waste occurrences which negatively influence their performance. Nevertheless, limited studies have been performed aiming at waste assessment, especially in developing countries. In the current study, 24 sources of wastes were identified through a review of previous works, consolidated by interviews with Moroccan construction experts. Subsequently, a structured questionnaire was used to survey 330 Moroccan construction professionals to explore the critical sources of wastes in Morocco. “Activity start delays” was found to be the most significant source of waste according to the perceptions of the surveyed respondents. Furthermore, the statistical analysis revealed that the top three ranked waste categories were: 1—unused employee creativity, 2—delay and waiting, and 3—defects/errors/corrections. These findings are expected to help practitioners and managers of construction projects to focus their resources and interest on the main sources of wastes and to establish, therefore, more effective strategies for waste reduction.
