Ensuring seamless operations from day one is non-negotiable when building a mission-critical data centre. That’s where Data Centre Commissioning (CxM) plays a pivotal role. Whether you're constructing a Tier 3 facility or scaling a 50MW hyperscale data centre, commissioning ensures every power, cooling, IT, and security system is tested, validated, and ready for full operations.

In this article, we unpack the fundamentals of CxM and why it’s essential for operational success. Plus, discover how Sixfold Group delivers a streamlined commissioning experience that guarantees results.

What Is Data Centre Commissioning (CxM)?

Commissioning Management (CxM) is a structured, multi-phase process that verifies all building systems perform according to the owner's project requirements and design intent. It spans from pre-design to handover and includes planning, inspections, testing, documentation, and validation.

In the context of data centres, CxM involves detailed verification of critical infrastructure like:

• Power distribution units (PDUs)
• Uninterruptible power supplies (UPS)
• HVAC and cooling systems
• Fire protection
• Networking and BMS integration

Why It Matters

Data centres are highly complex environments where even minor system failures can lead to catastrophic downtime. CxM reduces risk, improves energy efficiency, and ensures system integrity from day one.

Key Benefits of Data Centre Commissioning

✅ Operational Readiness

CxM confirms that all systems function under both normal and emergency conditions—before going live.

✅ Cost & Time Savings

Catching issues early prevents costly rework, schedule delays, and unplanned outages.

✅ Energy Efficiency

Proper commissioning improves system performance, helping facilities meet ESG and PUE targets.

✅ Regulatory Compliance

CxM ensures adherence to global data center standards, from Uptime Institute Tiers to ASHRAE guidelines.

The 4 Phases of Data Centre Commissioning

1. Pre-Design & Design Phase

Commissioning starts with intent. In this phase, commissioning professionals collaborate with engineers and stakeholders to define:

• Operational goals
• Performance metrics
• Initial commissioning plan
• Design reviews and gap analysis

2. Construction Phase

Once construction begins, the CxM team verifies installation standards and readiness for testing. Tasks include:

• Factory Acceptance Tests (FATs)
• Equipment inspections
• Witness testing of key components
• Compliance checks with design specs

3. Testing Phase

This is the heart of CxM. Testing includes:

• Pre-functional and functional testing
• Integrated Systems Testing (IST)
• Simulations of failover scenarios
• Black start and load shedding tests

4. Operational & Handover Phase

After all tests pass, systems are handed over to the operations team with:

• Final commissioning report
• As-built documentation
• Performance data logs
• Staff training and ongoing monitoring protocols

FAQs About Data Centre Commissioning

What’s the difference between CxM and CxA?

CxM (Commissioning Management) oversees the entire process, while CxA (Commissioning Authority) is the third party responsible for verifying execution. Sixfold Group provides both for complete coverage.

When should commissioning begin?

Ideally, CxM should begin at the design stage to influence planning, improve constructability, and streamline testing.

Is commissioning required for Tier certification?

Yes. Uptime Institute requires documented commissioning processes for Tier III/IV certification, especially during integrated systems testing.

What’s included in a final commissioning report?

It includes test plans, procedures, results, issue logs, compliance statements, and lessons learned—delivered in a formal, traceable format.

Does Sixfold Group offer commissioning for live sites?

Yes. We also provide retro-commissioning and recommissioning services for live data centres undergoing upgrades or expansion.
