Estimation of Construction Wastes Based on the Bill of Quantitiy in South China

Abstract

In this paper, taking the South China area as an example, a list of construction wastes has been established based on the bill of quantities, and a calculation method for the production of construction waste of new residential projects has been proposed. According to the existing research data, the scrap rate of the main materials is obtained, and the waste production of the newly-built project is estimated, which is 0.326 m³per unit area . The model in this article estimates the amount of construction waste and promotes the classification and reduction of construction waste at the construction site. It is recommended to adopt source reduction measures, implement a classification system and improve relevant laws and regulations, as well as optimize the waste market. Meanwhile, this model includes waste production budget into bidding, providing reference for improving the management level of domestic construction departments.
