1. Smart Construction Objects (SCO) and RBIMP Gateway
SCOs and Gateway are able to capture the real-time construction data so as to support the decision-making in HKHA’s information systems like BIM and HOMES. That could be enhanced the data sharing within the high level decision-making entities and front-line construction sites. That means, the advanced decision-makings could real-timely reflected in the construction site, while, the real-time data such as prefabrication manufacturing progresses, prefabrication transportation statuses, etc could be fed back to HKHA on real-time basis. That forms a closed-loop information interaction throughout the prefabrication housing construction.
2. Traceability and Visibility Tools
The RBIMP Traceability Tool allows identification of objects in a fully automated manner via radio waves. The RFID tags are embedded in the prefab parts and goes through the whole lifecycle of manufacturing, transportation assembly and maintenance. The RBIMP Gateway will be setup as a data collector on the prefab shop floor, transportation vehicle, cross-border check point, and construction site. All the RFID events are captured and stored on RBIMP tracing servers, which can be shared among other participants in the supply chain in a secured and controlled manner. The RBIMP Visibility Tool can be geographically distributed in the locations of different participators. For instance, the prefab manufacturers can setup their own RBIMP Visibility Tool for production planning and control. The logistics companies can use the RBIMP Visibility Tool for tracing the cross-border vehicles. The construction companies have on-site RBIMP Visibility Tool to manage project progress. All the data can be integrated and complied into different KPIs (Key Performance Indicators) and displayed in the central control room of HKHA.
3. RBIMP Data Source Interoperability Services (RBIMP-DSIS)
RBIMP-DSIS works as an information sharing adapter so that all the heterogeneous data sources could be seamlessly integrated. Fig 3.6 demonstrates the key principle of RBIMP-DSIS, which uses an Application Information Service (AIS) that serves as a middleware for providing information query service for different data sources, integrating isolated information islands in construction into BIM and HOMES in HKHA so as to address current challenges in information sharing.
