Under the global development of sustainable construction, the government devotes more and more efforts to the proper handling and recycling of construction and demolition wastes. In order for controlling those wastes to go into recycling plants or legal dumping sites for proper treatment, contractor of a building project is required to submit a waste handling plan to local EPA (Environmental Protection Agency) for review before they can start the work. In the plan, they have to estimate the expected quantity of wastes, and to state clearly, where they will go, how they will be treated, and so on. Later on, the contractor has to report the actual generation and handling of the wastes on line into the EPA Waste Reporting System. Therefore, the estimated quantity serves as a base for the local EPA to monitor and control the wastes in the remaining process of construction waste management. The objective of this research is to investigate the major factors influencing the waste quantity generated in the construction as well as demolition of a building project. Factors considered includes building floor areas, use purpose of building, its structural type, with and without basement, building contract dollars, whether a recycling program equipped on site, and so on. Several thousands of building construction and demolition waste records (cases) in the local Waste Reporting System are employed for the investigation and analysis. Statistical regression analysis is performed on each of the considered factors to identify the major ones influencing the waste quantity generated in a building project. The identified major factors are compared with those identified in the previous studies for further discussions. These factors can serve as a base for the local EPA to better audit and control the amount of wastes generated in a building project and facilitates the remaining process of waste management. Findings and conclusions are reported in the paper.
