Building for demand in data centres: power and adaptability for designers
Reviewed by Tom Sullivan

First reported on New Civil Engineer
30 Second Briefing
Europe’s data centre build-out is shifting to campus-scale schemes, with individual sites routinely designed for tens of megawatts and some projects now exceeding 150MW of IT load. Developers are pushing high‑density layouts, dual 132kV grid connections and large‑scale backup generation to secure power resilience while leaving space and structural capacity for future rack loads and cooling upgrades. For civil and M&E designers, the focus is on modular power blocks, flexible chilled‑water or direct‑to‑chip cooling corridors, and foundations that can accommodate phased vertical expansion.
Technical Brief
- Structural grids are being widened to accommodate heavier racks and cable routes without excessive transfer structures.
- Designers are reserving additional riser and plant space to retrofit liquid or direct‑to‑chip cooling later.
- Floor slabs are commonly detailed for future point‑load increases, with reinforcement patterns optimised for rack realignment.
- Civil layouts are leaving safeguarded corridors for extra HV feeders and chilled‑water mains to future buildings.
- Roof and mezzanine levels are being framed for potential extra AHUs, dry coolers or adiabatic units without strengthening.
- Stormwater systems are upsized early, anticipating higher condenser water discharge and hardstanding expansion across the campus.
- Fire compartments and escape routes are planned to remain compliant under phased infill of white space and added plant.
Our Take
Data centre schemes in Europe pushing beyond 150 MW put them in the same grid-impact bracket as major airports and rail hubs seen elsewhere in our Infrastructure coverage, meaning early coordination with transmission operators and city planners is now a de facto prerequisite rather than a nice-to-have.
Across the 803 Infrastructure stories in our database, only a subset of sustainability-tagged pieces deal with continuous 24/7 loads of this magnitude, which suggests permitting and ESG scrutiny for large European data centres is likely to converge with that applied to thermal power plants rather than conventional commercial buildings.
New Civil Engineer’s role as organiser of innovation and tech-focused awards in the UK (e.g. TechFest Awards 2025) signals that high-capacity data centre projects in Europe are increasingly being treated as testbeds for advanced grid-integration, cooling, and demand-response technologies rather than just large M&E jobs.
