As-Built BIM for Data Centers
The design model is not the building. An as-built model records what was actually installed, which is what operations will rely on for the next decades.

Why it matters
Maintenance, expansion and fault response all depend on knowing what is where. An as-built model that matches the installed system saves time and reduces risk in operation.
Capturing changes
- Log every site change with its reason and the affected elements.
- Verify the installed condition, for example with survey or inspection.
- Update the model and its data to match, and record the version.
- Reconcile drawings, schedules and the single-line diagram with the model at handover.
What to hand over
- The updated model and extracted drawings and schedules.
- Equipment data (ratings, manufacturers, serial numbers where required).
- Test and commissioning records. See the commissioning and handover checklist.

Frequently Asked Questions
What is as-built BIM?
A model updated to reflect the installed condition of the facility, including changes made during construction and the data from handover.
Why does it matter in a data center?
Operators need accurate locations, ratings and connections to maintain equipment, plan changes and respond to faults.
How do changes get captured?
Through a controlled process: site changes are logged, verified (for example by survey) and fed back into the model.
What is the usual gap?
The model is not updated after changes made on site, so the handover documentation does not match the building.
