Why European Data Centre Construction Needs Smarter QA: A Take on RLB’s 2025 Trends

The UK and Europe are in the middle of a data centre gold rush.

According to the RLB Data Centre Trends Report 2025, commissioned capacity has exploded, surging by nearly 300% since 2023. AI adoption, cloud growth, and geopolitical data localisation are driving massive demand. Hyperscale projects averaging 47MW are becoming standard. Everyone’s building fast.

But here’s the catch: when speed ramps up and complexity scales, quality becomes the first thing at risk. And in the world of data centres, poor quality isn’t just an internal issue,  it’s a critical failure that can delay go-live, jeopardise uptime guarantees, and put client relationships on the line.

This blog explores what RLB’s latest report tells us about the future of data centre construction and why QA teams need to step up, not step back.

What’s Fueling the Data Centre Boom?

The surge in data centre development isn’t random — it’s structural. And right now, three forces are converging to supercharge demand:

1. AI’s Explosive Infrastructure Needs

Artificial intelligence isn’t just trending — it’s transforming infrastructure. As RLB’s report highlights, data centre capacity is increasingly being designed around AI training and inference workloads, which require:

• Higher power densities
• Massive computational throughput
• Advanced cooling systems

Operators are scrambling to future-proof their facilities to support these new AI-driven demands. And with AI investments accelerating across Europe, this isn’t slowing down anytime soon.

2. Geopolitical and Regulatory Pressures

The push for data sovereignty is growing. Across Europe, stricter regulations regarding data residency mean operators must build local infrastructure, rather than relying solely on global hubs. That’s prompting hyperscalers and cloud providers to ramp up in-region builds, from Dublin to Frankfurt to London.

3. Private Equity and Platform Growth

The RLB report also spotlights a significant shift: more data centres are being speculatively developed by private equity-backed platforms. These developers are targeting fast builds with high scalability, creating a race to deliver capacity before demand peaks.

In short: AI is the spark, regulation is the accelerant, and private capital is fuelling the fire.

The High-Speed Reality of 2025

Let’s break it down. According to RLB’s report:

• • 53% of developers are concerned that the supply chain can’t keep up
  • Construction costs have jumped 12% year-on-year
  • 70%+ say supply shortages are delaying project delivery
  • Private equity and hyperscaler pressure is accelerating timelines
  • New builds are increasingly designed to be modular, scalable, and green

This is a pressure cooker environment.

The sector isn’t just growing, it’s evolving. Clients want resilience, sustainability, and speed. But they also expect rigour. Handovers need to be traceable. Issues need to be closed out properly. ESG goals need to be documented. If these are missed, you risk more than defects; you risk trust.

Where Quality Typically Falls Short

Delivering a data centre isn’t like delivering any other asset. It’s high-stakes, high-speed, and highly scrutinised. Yet too often, quality assurance still relies on outdated tools that aren’t built for the complexity of these projects.

We still see QA managed through:

• • Fragmented tools: PDFs, spreadsheets, and scattered emails instead of one central platform.
  • Delayed feedback loops: Issues are flagged days or weeks after they happen, not in real time.
  • Limited traceability: Documentation gets lost, or doesn’t meet compliance and client requirements.
  • Reactive workflows: Teams only discover problems when they’re already on the critical path.

In a hyperscale environment, this isn’t just inefficient — it’s risky. And as more data centres move toward modular, multi-zone builds, these gaps only widen without the right system in place.

The RLB report touches on this challenge, noting that as data centre projects scale in size and complexity, the ability to manage and share accurate, up-to-date information becomes mission-critical. Quality assurance, when disconnected or poorly managed, is one of the first areas to suffer, causing rework, delays, and friction at handover.

That’s why forward-thinking teams are investing in digital QA platforms like Visibuild to centralise information, automate traceability, and bring quality into the critical path, not bolt it on at the end.

Why QA Matters More in Data Centre Construction

Visibuild is already supporting QA on over $10 billion worth of data centre projects across Australia and New Zealand. These include complex, large-scale builds where precision, speed, and seamless closeout aren’t optional — they’re essential.

Our experience in the sector, outlined in more depth here, shows that quality can’t be treated as a last-minute task. Data centre clients expect:

• Traceable and auditable QA processes
• Rapid close-out cycles that don’t bottleneck final delivery
• Field visibility across every zone, trade, and team

And as more data centres move toward modular construction and integrated commissioning, QA must evolve to support that shift, not slow it down.

What the Experts Say

The RLB report features recommendations from industry leaders that align directly with how quality should be managed on modern projects:

This is exactly why Visibuild puts structured, centralised QA processes at the core. When information is buried in email threads or hard drives, collaboration breaks down. We help teams surface the right data at the right time — so decision-makers can move fast with confidence.

“Digital technology provides far greater visibility into the supply chain risks than has ever been possible. To mitigate these risks, integrate digital platforms and dashboards throughout the project life cycle and use real-time data analytics to identify potential disruptions before they happen.”
Michelle Zompi, Head of RLB Digital

Spot on. This kind of proactive, insight-driven approach is baked into Visibuild’s design. Real-time field data, inspection progress, and outstanding issues are visible across the team, so risks can be tackled early, not after they become a crisis.

Visibuild’s Take: Quality Built for Speed and Scale

Visibuild isn’t just a snagging tool. We help data centre delivery teams build quality into every stage of construction — in real time.

Standardised QA at Every Site

Create, manage, and update checklists that reflect client requirements, ISO standards, and project-specific needs — and roll them out across multiple sites with consistency.

Real-Time Field Visibility

Capture issues onsite with mobile checklists and defect photos. Instantly sync updates with your central dashboard. Whether you’re on a Tier IV hyperscale build or a smaller colocation site, your team has one source of truth.

Faster Closeout, Fewer Surprises

Avoid that end-of-project scramble. With Visibuild, teams can track QA status live, chase outstanding issues proactively, and walk into PC with confidence, not chaos.

Audit Trails That Write Themselves

Every check, comment, sign-off, and photo is logged automatically, ready for client reports, regulators, or ESG documentation without extra admin.

Quality Can’t Be an Afterthought

The data centre construction boom is a huge opportunity. But it’s not without risk.

Projects are getting bigger, faster, and more complex. Mistakes cost more. Oversights are harder to hide. And delivery teams are being held to a higher standard by clients, consultants, and regulators.

If you’re still managing quality through emails, Excel sheets, or siloed systems, now’s the time to rethink it.

At Visibuild, we’re helping teams shift from reactive QA to proactive, performance-led quality management — purpose-built for modern projects like data centres.
