Building Information Management (BIM)
Building information modelling (BIM) provides architectural 3D visualisation and a standardised way to share and exchange building information. Recently, there has been an increasing interest in using BIM, not only for design and construction, but also the post-construction management of the built facility. With the emergence of wireless smart built environment technology (WBAMnet), which embeds most spaces with smart objects to enhance the building's efficiency, security and comfort of its occupants, there is a need to understand and address the challenges BIM faces in the design, construction and management of future smart buildings. BIM can contribute to the deployment of a WBAMnet. Since BIM is designed to host information of the building throughout its life cycle, such system covers phases from architecture design to facility management.
Recent rapid advances in information and communication technologies have led to their pervasive use across industry sectors, including building construction. Currently taking a central stage in the construction and management of emerging smart built environments. Here, "smart environment" refers to an environment that has been embedded with smart objects, such as sensors and actuators, with computing and communication capabilities, making the environment sufficiently 'smart' to interact intelligently with and support their human users in their day-to-day activities.
BIM serves as a data repository for the physical information of smart objects. For maintenance and asset tracking in the building post-construction phase, the hardware information of smart objects can be recorded, and their installation locations can be documented and visualised in 3D. On the other hand, BIM provides a perfect ontology database for WBAMnet. With the introduction of BIM, each smart object can be profiled through its information exchange interface. Because BIM is standard compliant; the WBAMnet middleware extracts data formats of smart objects and other local building information for viewing from a local ontology database and the Cloud SaaS Elastic Pool database.
