Abstract Rapid economic growth and urbanization in China lead to extensive construction activities which generate a large amount of construction waste (CW) inducing a great adverse impact on the environment. Therefore, how to implement effective construction waste management (CWM) has received increasing attention from construction stakeholders and researchers in the past few decades. The aim of this study is to provide a simulation model for CWM which can help to reveal the amount of CW generation and quantify the effects of various policy implementations. With the agent-based modeling (ABM) approach, the inter-relations between stakeholder agents and the CWM process are analyzed and a simulation model integrating four subsystems is built. The model is then developed and programmed with Repast Simphony software. The results indicate that the practitioners’ awareness and ability of CWM as well as their communications should be further improved. Furthermore, the regulations for the use of low-waste technologies, disposal charging scheme and incentive mechanism should be further refined to reduce landfill, increase the ratio of reuse or recycling. The findings can provide guides and references for predicting CW generation and making effective CWM policies. Keywords Construction waste modeling Repast simphony

Introduction
With the acceleration of urbanization and urban renewal, huge construction, renovation and demolition activities can be found across China causing the quantities of construction and demolition waste (CDW) to increase at a high speed in the architecture, engineering and construction (AEC) industry. According to statistics, the amount of CDW generated each year has accounted for 30–40 % of the total municipal solid wastes in China, among which more than 100 million tons of wastes are generated due to the construction of new buildings [1]. However, most of the CW is delivered to suburban or rural areas for landfills, which has become an urgent issue due to not only its cost efficiency but also its adverse effect on the environment. Therefore, it is imperative to research how to implement effective CWM to promote the urban sustainable development. In the past few decades, many researchers devote themselves to the study of CWM by adopting diverse approaches to investigate different topics ranging from CW generation, reduction, reuse, recycling to assessing the effectiveness of CWM, among which quantificatio
