Waste generation has negative impact on the environment, productivity, budget, and project completion schedule. Nevertheless, no study has been carried out in Morocco aiming at assessing the common causes of waste generation. In the current study, 25 causes of wastes were extracted from previous studies and, then, validated through semi-structured interviews with Moroccan construction experts. Subsequently, a questionnaire method was used to survey 330 Moroccan construction practitioners. The frequency method was employed to measure the level of occurrence of each item. Statistical Analysis of the collected data indicated that the five most recurrent causes of wastes are: 1- late payment, 2- lack of training for employees, 3- lack of waste management strategy, 4- inefficient planning and scheduling, and 5- lack of collective planning. These findings enable academics and engineering managers to benefit from increased awareness regarding the most common causes of wastes and, hence, develop appropriate strategies for improved performance through waste reduction.
