Christof is a software professional with extensive experience. However, he did his doctorate in chemistry because that is also pretty complex. Christof is a key account manager and also one of the thought leaders at RIB IMS. As such, he already solves questions today that others will only ask themselves later. When Christof doesn't care about customers or ponders CAFM, BIM, IoT, AR, KI and other acronyms, he enjoys the free time with his family.

The BIM process is an excellent provider of data for the operational phase. The knowloedge CAFM-Manufacturers and users for quite a while, but there are no standardization guidelines in order to be able to transfer the data of a BIM model into a CAFM system relatively easily. The VDI has now taken up this aspect in its series of guidelines 2552 to BIM will be expanded to include sheet 6 "BIM in operation".


Of course, experts in the field will now want to object that IFC and CoBIE already have two standards on the market that can be used to import data. The CAFM-Connect approach of the CAFM Ring is a possible anchor for all those who want to import data from BIM into CAFM. But all of these approaches are incomplete, because they only have selected data in view, only the data without accompanying processes and only the one-way transport.

From B to C ...

It is a complex 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 common practice, but everyone reinvents the wheel in order to be able to do everyday work that everyone can and will benefit from. Comprehensive and global standardization would be desirable, in both directions.

... and from C to B

Because one thing is clear: BIM is not just an excellent tool for building a new building. In principle, BIM models are also helpful when converting and renovating, even when dismantling. Therefore, data should also be able to be transferred from the CAFM back into the BIM, i.e. from C to B. Therefore, comprehensive and global standardization in both directions would be desirablen.

Use cases everywhere

The need for interoperability of the systems is evident, because use cases can be found in many different ways:

  • 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 admission.
  • Maintenance: The continuous maintenance process is a requirement of the operating phase, which must already be taken into account in the BIM model, for example, when maintenance activities by manufacturers are stored on the property.
  • Simulation of operating costs: The operating costs can be simulated based on BIM even before the installation. However, this requires CAFM software that has already integrated the tools for costing and forecasting.
  • Tenders: With access to BIM models, robust tenders can be carried out at an early stage - possible from AVA software, but also from 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.

Matthias Mosig from der TÜV SÜD Advimo GmbH examined the most important BIM use cases and answered the question “Do you keep what you promise?”. Nice that the topic also gets attention from the consultant side.

Value creation even before construction

The benefits of a close integration of BIM and CAFM are clearly linked to value creation scenarios - before, during and especially after construction, because operation accounts for all building costs for more than 70%. It is therefore essential to be able to work with BIM data in CAFM systems as early as possible. And that's why we, as RIB IMS, are involved in the “BIM in Operation” working group of the VDI.
