Six levels. One verifiable handover.

Reviewing the Owner's Project Requirements (OPR), Basis of Design (BOD), and initial engineering diagrams to catch flaws early.

Testing critical equipment — generators, UPS systems, chillers — at the manufacturer's facility before it is shipped.

Inspecting equipment upon delivery to verify no transit damage occurred and that it matches design specs.

Verifying that equipment is installed correctly and safely energizing individual assets for the first time.

Torture-testing individual systems under simulated full operational loads — often using load banks — to meet performance metrics.

The 'Black Building' test — the entire data center is stress-tested simultaneously, simulating complete utility power failures.

Compiling final documentation, training the facility operations team, and officially transferring ownership of the live data center.
