VDI and BIM in operation
The BIM-process is an excellent supplier of dates for the operating phase. That know CAFM-manufacturers and users for quite a while now, but there is a lack of standardisation guidelines to make it relatively easy to convert the data of a BIM model into a CAFM-system. This aspect has now been taken up by the VDI, which has published its series of guidelines 2552 on BIM will be expanded to include Sheet 6 "BIM in operation".
Of course, those familiar with the subject will now want to object that with IFC and CoBIE there are already two standards on the market by means of which a data import can certainly be realised. The CAFM Connect approach of the CAFM Ring is also a possible anchor for all those who want to import data from BIM into CAFM. But all these approaches are incomplete, because they only have selected data in mind, only the data without accompanying processes and also only the transport in one direction.
From B to C ...
It is a laborious task to actually get data from B to C, namely from the BIM model into the CAFM system. Interfaces with import tables have long been a practised way, but everyone is reinventing the wheel to be able to do everyday work from which everyone can and will benefit. Comprehensive and global standardisation would be desirable, in both directions.
... and from C to B
Because one thing is clear: BIM is not only an excellent tool for constructing a new building. BIM models are also helpful in principle for conversion and renovation, even for deconstruction. Therefore, it should also be possible to play data from CAFM back into BIM, i.e. from C to B. Comprehensive and global standardisation in both directions would therefore be desirable.
Use cases everywhere
The need for interoperability of the systems is evident, because use cases are manifold:
- Import of room and system book: Direct transfer of all relevant construction data from the BIM model instead of the total loss of necessary room and plant data after completion of construction and costly new recording.
- maintenance: The continuous maintenance process is a requirement of the operational phase that must already be taken into account in the BIM model, for example by storing maintenance activities by manufacturers on the object.
- Simulation of the operating cost: Even before construction, the operating costs can be simulated based on BIM. However, this requires CAFM software that has already integrated the tools for cost calculation and forecasting.
- Tenders: With access to BIM models, reliable tenders can be carried out at an early stage - possible from one source. AVA- but also from a CAFM software.
- Smart processes: Buzzword topics such as Smart Maintenance and Smart Service also benefit if IoT sensors are already integrated in the BIM model and the digital twin BIM + IoT contains.
At this year's digital Servparc, Matthias Mosig from the TÜV SÜD Advimo GmbH took a close look at the most important BIM use cases and answered the question "Do they deliver what they promise? It's nice to see that the topic is also getting attention from consultants.
Value creation even before construction
The benefits of a close integration of BIM and CAFM is clearly linked to value creation scenarios - before, during and especially after construction, because operation accounts for over 70% of all building costs. It is therefore essential to be able to work with BIM data in CAFM systems as early as possible. And that is why we are involved as RIB IMS in the VDI's "BIM in Operation" working group.
