MEP fit-out in a data centre environment encompasses three interconnected technical domains. The electrical domain covers the primary power distribution from the grid connection or UPS input through to the power distribution units at rack level — including transformer, switchgear, UPS systems, generator sets, and static transfer switches. The mechanical domain covers cooling — from primary cooling plant through to the in-row, rear-door, or direct liquid cooling systems at rack level. The plumbing domain covers the cooling water and glycol circuits that serve liquid cooling systems and the fire suppression systems that protect the IT load.

Each domain has its own specialist installation contractors, and the interface between them is where coordination failures typically occur. Power distribution routing and mechanical routing must be coordinated to avoid conflicts that require costly remediation during installation. The cooling water circuits must be pressure-tested and commissioned before any IT equipment is brought into the space. And the power system must be tested to its specified redundancy level before any offtaker is told their capacity is available.

NCP certification — NVIDIA Cloud Partner site approval — is a mandatory gate for any operator intending to host GPU infrastructure. An operator that claims GPU readiness without NCP certification is representing a capability it cannot deliver. Armason verifies NCP certification status as a hard gate in the fit-out process, not a preference — an installation schedule committed before certification is confirmed creates programme risk that is difficult and expensive to manage when the certification process raises questions about the facility specification.
