UAE infrastructure moves underground

The United Arab Emirates is reassessing the design and siting of two of its largest infrastructure ventures, moving significant components underground to bolster protection against potential attacks. One is a proposed 5-gigawatt AI data center project being developed with US technology partners, originally conceived as a single 10-square-mile campus in Abu Dhabi but now likely to be implemented as a dispersed national network of facilities. The other is a multibillion-dollar plan to relocate Dubai’s main airport south of the city, with underground fuel storage tanks and enhanced defensive measures under consideration.

"The changes will not shrink the plan to ferry 250 million passengers a year through the new hub," said Paul Griffiths, chief executive officer of Dubai Airports, describing how the relocation project’s ambition remains intact despite design changes.

Context and details

Officials and project planners are weighing a shift from concentrated surface infrastructure to a mix of subterranean and distributed sites. The AI data center project, which has been planned in partnership with US technology firms, was originally mapped as a contiguous campus in Abu Dhabi spanning roughly 10 square miles. Those plans are being reworked so the capacity is spread across multiple sites nationwide. Among the defensive measures being explored are the integration of air defence systems and constructing portions of facilities underground.

For the airport relocation, Dubai Airports has described the programme as a multibillion-dollar undertaking to establish a new hub capable of handling unprecedented passenger volumes. The scheme aims to accommodate up to 250 million passengers annually, a figure Griffiths affirmed will not be reduced as a result of recent design reconsiderations. Specific modifications now on the table include underground fuel storage tanks, which would reduce above-ground vulnerability of critical fuel supplies.

• AI data center: 5-gigawatt capacity; US technology partners involved; shift from a single 10-square-mile Abu Dhabi campus to distributed facilities nationwide.
• Dubai airport relocation: multibillion-dollar project to move the main airport south of the city; design may include underground fuel storage; capacity target remains 250 million passengers per year.
• Security measures under review: air defence systems, underground construction, and dispersion of critical infrastructure to reduce attack risk.

Outlook

Planners appear to be prioritizing resilience and survivability in critical national infrastructure, balancing vast capacity goals with a revised physical footprint that emphasizes dispersion and subterranean protection. For the AI data centre, converting a single campus into multiple sites could complicate logistics and increase construction costs, but would reduce single-point-of-failure risk and make sites harder to target. For the airport, adding underground fuel storage and other hardened facilities will add complexity and cost to an already ambitious relocation, but Dubai Airports leadership insists the annual throughput target of 250 million passengers remains achievable.

As both programmes move from blueprint to implementation, engineering, security and procurement teams will need to coordinate closely with international technology partners, contractors and defence planners to reconcile scale, cost and safety objectives while keeping the projects on schedule.
