Before a data centre becomes operational, it is critical to ensure that every system performs as intended and meets the highest standards of reliability and resilience. Through rigorous analysis, independent review and structured testing, we validate that the design and infrastructure can support continuous, uninterrupted operations.
We conduct Single Point of Failure (SPOF) analysis across electrical and mechanical infrastructure to identify critical vulnerabilities that could compromise operational continuity. Our systematic assessment evaluates power distribution paths, cooling system redundancy, utility supply configurations, control system dependencies, and failure mode scenarios to verify that redundancy strategies are correctly implemented and aligned with the target availability tier (Uptime Institute Tier certification, 5-nines availability, or client-specific SLA requirements).
Our independent peer review process provides objective third-party assessment of mission critical design packages to verify compliance with industry standards (IEEE, IEC, ASHRAE, NFPA), validate design assumptions, and ensure alignment with performance requirements and operational objectives. Acting as owner's engineer or technical advisor, we review system designs, equipment specifications, redundancy architectures, and integration strategies to confirm design integrity, identify potential risks or optimisation opportunities, and provide technical assurance before construction commitment or contractor mobilisation.
We conduct systematic design validation and compliance reviews to verify that mission-critical facility designs meet applicable electrical codes (NEC, IEC, and BS standards), mechanical standards (ASHRAE and IMC), fire and life safety requirements (NFPA), and regional regulatory frameworks. Our reviews assess design documentation against local authority requirements, utility provider specifications, and client operational standards to confirm the facility will achieve regulatory approval, perform safely and efficiently, and align with the client's availability and operational objectives.
We provide commissioning management and oversight services to verify that electrical and mechanical systems are installed, integrated, tested and performing according to design intent and operational requirements. Our commissioning process coordinates Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), Integrated Systems Testing (IST), and witness testing protocols across power distribution, UPS systems, generators, cooling infrastructure, controls, and monitoring systems, ensuring all mission critical systems achieve specified performance levels and reliability targets before operational handover.
Integrated Systems Testing (IST) validates the coordinated performance of electrical, mechanical, and control systems under simulated operational and failure scenarios. Our IST process verifies power distribution failover sequences, UPS transfer operations, generator start and synchronisation, cooling system response to load changes, and control system integration to confirm that all mission critical infrastructure responds correctly during normal operations, maintenance events, and simulated equipment failures, ensuring the facility achieves its design redundancy level and availability targets before go-live.
We conduct reliability and operational readiness assessments that evaluate the technical performance and resilience of building systems prior to operational handover. Our assessments verify that all mission critical infrastructure has been commissioned successfully, redundancy mechanisms function as designed, monitoring and alarm systems are operational, and the facility is technically capable of achieving its design availability level and performance targets under both normal operations and simulated failure scenarios.
