Construction projects can generate various types of waste, including solid, liquid, and gas waste. If this waste is not managed effectively, it can cause disruptions to project activities and have negative impacts on the surrounding environment. To address this issue, research was conducted to identify the factors causing construction waste and the methods for managing it in construction projects. This study involved distributing questionnaires to project managers who are currently or have previously been involved in construction projects in Bali. The data from these questionnaires were then tabulated and analyzed using Factor Analysis to identify the primary causes of construction waste with the assistance of SPSS software, and the Scoring Method was used to evaluate waste management practices. The analysis revealed that the dominant factors contributing to construction waste include: Worker competence and skills, Material handling not in accordance with work procedures, Material quality not meeting specifications, Inadequate Standard Operating Procedures (SOP). The most commonly implemented construction waste management practices in projects in Bali include: having clear procedures for material handling and storage, conducting strict and regular supervision of workers to minimize errors, storing materials in weather-protected and easily accessible locations, reusing materials for tasks where leftover materials can still be used, and regularly monitoring and evaluating construction waste management.
