The Need for Convergence of BIM and 3D Imaging in the Open World

Effectively controlling a facility during its entire life cycle demands automated and rich information flows. These flows require the establishment of cyber- physical systems delivering bi-directional interoperability between the physical facility and its counterpart virtual Building Information Modelling (BIM) model. For example, during the construction stage the provision of real-time quality control against the as-designed BIM model ensures smooth construction processes and increases the promise to the owner that what is constructed is what has been designed.

Already, research and practice have demonstrated the value of on-site mobile devices and Radio Frequency Identification (RFID) technology to provide a unique link between physical and virtual objects. Motamedi et al. [5] have shown tracking of task and material during construction utilising RFID technology and open standard BIM models, i.e. Industry Foundation Classes (IFC) BIM models. In fact, current cyber- physical systems rely heavily on RFID technology as it provides a valuable means of identification of physical objects, that is creating the links between the real objects and their virtual counter-parts. However, RFID does not permit the acquisition of information about those objects, such as their as-is geometr y. As a result much human intervention remains required updating BIM models, e.g.
