From Design Review through Integrated Systems Testing: gated L1–L5 commissioning for data centres and high-density AI facilities.
Commissioning is the systematic verification that a facility performs as an integrated whole, in accordance with the Owner's Project Requirements and the Basis of Design. Installation confirms that equipment is in place. Commissioning confirms that it performs — individually, together, and under the conditions the facility was designed to meet.
MCE acts as Commissioning Authority on behalf of the owner. We hold no design interest and no construction interest in any project we commission, and our findings are reported to the owner against the specification, without obligation to any other party on the project.
The value to the owner is direct. Deficiencies are identified and resolved within the construction contract, while responsibility still rests with those who built the facility. Integration issues that cross vendor boundaries are found during testing rather than in service. Systems are placed into operation with their performance demonstrated, witnessed and documented rather than assumed.
Commissioning scope is defined in the Commissioning Plan and agreed with the owner at the outset. On data centre projects, MCE's scope typically covers:
Utility service, medium- and low-voltage distribution, standby generation, UPS systems, transfer and switching equipment, and distribution to the rack — including load acceptance and response to loss of source.
Chilled water plant, air handling, containment and heat rejection, verified for capacity, balanced distribution, control stability and recovery under design and off-design conditions.
Coolant distribution, direct-to-chip and rear-door cooling, loop integrity, and leak detection and containment.
Building and electrical power management systems, protection and control settings, and alarm and sequence verification.
The behaviour of all systems together under simulated failure, including transfer, ride-through and recovery.
MCE applies a gated five-level framework. Each level defines what is being verified, progressing from design documentation through to the completed facility. A system advances only once the preceding level has been signed off, and progress is tracked and reported to the owner throughout the program.
Design review is where the leverage is. A finding raised against the documentation costs a fraction of the same finding raised during integrated systems testing, and it is the level MCE invests in most heavily — the deliverable owners come to us for.
Testing is executed in accordance with NETA ATS, NFPA 110, IEC/IEEE, ASHRAE and AHRI practice.
High-density GPU deployments introduce cooling infrastructure that traditional air-cooled commissioning does not address. MCE commissions liquid-cooled facilities within the same gated framework, extending it to cover:
Verification of distribution units, primary and secondary loops, and loop integrity and cleanliness before liquid reaches live equipment.
Functional verification of detection, alarm and isolation response, and of containment provisions, ahead of energisation.
Verification of the control sequences linking facility cooling, coolant distribution and rack-level cooling as a single coordinated response.
Recorded verification of cooling performance and facility efficiency across progressive load steps, to design capacity and beyond.
Commissioning produces the record that supports acceptance, operation and future accountability. MCE's deliverables include:
An in-depth review of the design across every critical system — power, cooling, controls, fire and life safety — issued as a consolidated design pack for a resilient build: redundancy and topology, single points of failure, commissionability, and what must change before construction commits it. Written to the robustness of each critical system and to the availability the facility is targeting, up to five nines.
Scope, responsibilities, level definitions, test sequence and acceptance criteria, issued before work begins.
Executed checklists and test scripts, witnessed and dated, recording measured results against acceptance criteria.
Maintained throughout the program, prioritised, and tracked to closure prior to substantial completion.
The consolidated verification record, including performance results, failure-mode results and compliance data.
As-built records, O&M documentation, warranty registers and operating procedures, compiled through the program rather than at its close.
Operational Readiness support — training, procedures and staffing review — is available as an optional addition to the program.
The commissioning record remains the owner's evidence of verified performance long after project completion, supporting operations, insurance, financing and regulatory requirements.
Our commissioning team brings experience from more than 50 major data centre projects globally, and from several hundred megawatts of data centre infrastructure reviewed or assessed. The team is PEng-licensed and acts solely as the owner's representative.
Design intent, redundancy and topology assessed before construction commits the facility to them.
How the facility behaves over its operating life, and where single points of failure remain.
Whether existing power and cooling can carry high-density GPU load, and what it takes to get there.
Independent verification, on the owner's side, from design review through integrated systems testing.
