Construction activities have significant and irreversible effects on the environment, and generates large amount of waste. In Hong Kong, as in many countries the disposal of construction waste has become a severe social and environmental problem. Prefabrication has been identified as a solution to reduce the generation of construction waste arising from design and construction phases. In recent years, the government has implemented incentive schemes, the Joint Practice Notes 1&2, with gross floor area exemptions granted for building development employing green and innovative building technologies and prefabrication. These Joint Practice Notes were recently revised in 2011, modifying the maximum area allowed for exemption when using prefabricated walls. This research project will attempt to assess the impact of the Joint Practice Notes on the use of prefabrication in high-rise building and its waste reduction level. In this research project, data will be collected and analysed , using combination of quantitative and qualitative methodologies such as questionnaire survey, detailed case studies of recently completed buildings in Hong Kong (including site observations), and face-to-face interviews. The triangulation between results will allow validation of the collected data. This research could significantly promote the aspiration towards a more environmentally responsible and sustainable building industry in Hong Kong to achieve a healthy built environment and efficient use of resources.
