On 13 November 2008, the governments of Hong Kong and Shenzhen signed the Cooperation Agreement on jointly undertaking comprehensive planning and engineering study (P&E Study) including environmental impact assessment on the development of the Loop on the basis of mutual benefits. The P&E Study, jointly conducted by the Planning Department and Civil Engineering and Development Department, is to formulate a comprehensive plan for the development of the Loop. According to the Environmental Impact Assessment Ordinance (Cap. 499), contractors are required to provide an Environmental Impact Assessment Report (EIA) to the Environmental Protection Department (EPD) which addresses environmental and social impacts, mitigation measures, related management, and monitoring plans to minimize environmental impact that can be caused from the projected development cycle. While providing the EIA report, the Environmental Protection Department attempts to find new solutions to several problems regarding difficulty in immediate data collection, data tracking, and tracing. In this project, we plan to develop a series of sensors and an integrated 3D system to collect the envoronmental data such as Air, Water and constructure waste infromation for EPD to effectively track and trace the enviornmental and pollution data in a development area. EPD has chosen the Lok Ma Chou Loop as trial site for this project .
