| Abstract: |
The building industry in Hong Kong is facing tremendous challenges in managing the progress of multiple major infrastructure projects and as demanding high quality building lifecycle management. Modern buildings have advanced facade designs, structures, and MEP (mechanical, electrical and public health) systems to cater for energy-efficient operations. The increase in complexity calls for the use of more sophisticated building information model (BIM) systems such as Autodesk Revit. The project extends the current geometric information in BIM by including semantic information to enhance operations in construction and facility management. By integrating sensors location information in BIM allows better facility management. Using Bluetooth mesh network, sensors and facilities information can be mapped into BIM model through the Bluetooth protocol. Latest upgrade to the Bluetooth standard is used to overcome current Bluetooth deficiencies in power consumption, data transfer rate and privacy settings. The project will present a novel multi-sensor network based on Bluetooth technology to provide updated tagged building facilities spatial location and their associated semantic attributes. Building facility managers can monitor the maintenance and sensors information via the on-line BIM portal. |
