The study divided into 3 parts. ; 1) The causes of the wastes 2) the types and quantities of construction waste 3) current status of waste management and recommendations for a better approach of construction waste management. The results showed that: 1) All of the construction phase which consists of design/documentation, procurement, material transport; and storage phase, the construction phase is the phases that generated most of the waste process for both precast concrete structure and conventional concrete structure system; 2) Rebar and structural steel waste are the two largest of waste types in conventional construction project and wood waste is largest waste type in the precast concrete system; 3) The most common waste management method is proper storage and inventory control, while the least is the policy of waste management.
