Who makes cx agents for AI data centers

A commissioning agent is the independent party that proves the building works before anyone hands over the keys. They write the test scripts, witness the tests, document the results, and — the part that gives the role its value — they work for the owner rather than for the contractor whose work is being tested. The testing runs in levels, from factory acceptance of individual equipment through to integrated system testing where the whole facility is run at simulated full load and faults are deliberately injected: utility failure, generator failure, UPS transfer, chiller trip, all of it with load banks standing in for the compute that has not arrived. Integrated testing is where the failures that matter are found, because it is the only stage that exercises the interactions between systems that were each designed and installed by different parties. Skipping or compressing this is a recognisable pattern behind facility failures, and schedule pressure on AI builds pushes exactly that way. What to look for is whether commissioning is genuinely independent or performed by the design or build team, whether integrated testing at full load was actually done rather than deferred, and whether the documentation was handed over — the test results become the baseline that future maintenance is judged against, and a facility without them has lost its reference point.
