Data centres at risk of disuse: planning and reuse lessons for engineers
Reviewed by Joe Ashwell
First reported on New Civil Engineer
30 Second Briefing
Government has been accused of having no contingency plan for large-scale data centres if an AI investment bubble bursts and facilities become stranded assets, a gap campaigners call “alarming”. With new hyperscale campuses typically demanding tens of megawatts of grid capacity, deep foundations, extensive cooling infrastructure and multi-decade planning consents, critics warn that unplanned obsolescence could leave local authorities managing redundant, highly serviced shells. Engineers are urged to consider future-proofing, adaptive reuse of high-spec M&E systems, and decommissioning strategies at the planning and design stage.
Technical Brief
- Absence of a statutory decommissioning framework leaves redundant high‑load electrical and cooling systems unmanaged long‑term.
- Without mandated decommissioning, large diesel backup plants and fuel storage could remain on brownfield sites indefinitely.
- Fire‑suppression gases, batteries and high‑capacity switchgear may sit unmaintained, increasing arc‑flash and fire risk.
- Structural frames and deep foundations would likely be retained, but no guidance exists on safe partial strip‑out.
- Local planning authorities currently lack central government guidance on re‑zoning or safely repurposing such serviced shells.
- Emergency access, egress and compartmentation were designed for live data use, not derelict or intermittent occupancy scenarios.
Our Take
New Civil Engineer’s recent webinar on BIM, CDEs and the ‘data handover gap’ suggests that concerns about what happens to digital infrastructure at project close-out are already live in the sector, and the question of disused data centres extends that risk from data to large physical assets.
Because New Civil Engineer also curates innovation-focused initiatives like the Heathrow early careers competition and the Bridges Challenge, this critique of government planning may feed directly into future calls for design standards or competitions around adaptable, reconfigurable data-centre structures.
