The number of service providers involved in TBM is often large. If the documentation of responsibilities with contact persons and associated SLAs is incomplete or not accessible, this leads to avoidable delays when important systems fail, which may even result in personal injury.

A lack of documentation of the security certifications of building services systems, including dates for necessary renewals, can lead to expired certifications not being renewed in time. This can result in violations of the law, danger to life and limb depending on the building services system in question, and damages not being settled via the appropriate insurance policies.
