An integrated project extranet design prototype : e-AEC for architects, engineers and contractors in Hong Kong and Mainland China

This paper presents an integrated project extranet design prototype for the architects, engineers and contractors in a typical construction setting in Hong Kong and mainland China (known as "e-AEC"), with the aim of achieving technological and organizational integration. Internet, Information-sharing, Database, and Firewall technologies are applied for achieving such an aim, and discussions are provided as to how e-AEC can be used to support the construction industry, which has been slow in adopting Information Technology. Previous literature on project extranets and related commercial products are provided. A questionnaire survey with local construction professionals was conducted to identify the requirements of a construction project extranet. Two key requirements have been identified, including information database and interactive services such as online forum, engineering and management database, files transfer, and industry newsletters. In this connection, the benefits of project extranets and the barriers to successful implementation of project extranets have been identified. A case study on a railway project was conducted to evaluate the effectiveness of e-AEC. The findings suggest that it could be an effective project information and communication management tool.Department of Civil and Environmental EngineeringDepartment of Building and Real Estat
