BIM Model Management for BIM-Based Facility Management in Buildings

Summaries of the responses from the interviews.

No.	Responses
1	Interviewed by BIM manager: It is very important for owners to know which FM information needs to be tracked and managed in advance. There are many BIM models to be developed during the operation stage. Without careful consideration and planning, there will be serious time consuming problems in practice.
2	Interviewed by BIM manager: It takes lot of time to track and manage updating and revised BIM-FM models from different participants during the process. I suggest that it will be helpful and effective when the newest result of BIM-FM model modification and development can be traced and managed through the online system. It will be useful and helpful for responsible managers.
3	Interviewed by FM/BIM engineer: In our organization, some of the BIM-FM models were updated and revised many times. Sometimes, I adopted old BIM-FM models for FM. Therefore, it is necessary and helpful to provide the newest BIM-FM models through the centralized storage platform.
4	Interviewed by FM/BIM manager: When a new facility is purchased during the operation stage, the owner-operator FM organization will not be notified to develop the new BIM model for FM. Therefore, it is necessary to provide management mechanisms to develop BIM models for FM if the new facility will be planned to have the integration of FM and BIM.
5	Interviewed by BIM manager: Based on my experience, most nongeometric information in BIM-FM models are blank or have errors. Without suitable and clear employer information requirements and planning, it will be very difficult for the general contractor to enter the required nongeometric information of all BIM-FM models during the project closeout stage.
6	Interviewed by BIM engineer: For the effective implementation for the management of BIM-FM models, it is necessary and helpful to provide a management platform to assist in the development of new BIM-FM models and modifications tasks. Furthermore, there is important information necessary for this to be traced and managed. This information should include the status of the modeling work and finished BIM-FM models for new development or modification.
7	Interviewed by BIM engineer: Usually I need to access the version history and record of changes regarding updating the BIM-FM model. Therefore, it will be useful and effective for me if the system can provide the historical modification records regarding the selected revised BIM-FM model.
