A contractor has won the bid to develop a 6GW data centre campus infrastructure project in Saudi Arabia.

Al-Yamama Company for Trading & Contracting, a Dammam-based construction firm, has won a contract to develop infrastructure for a planned 6GW hyperscale artificial intelligence data centre campus in Riyadh. The project will be delivered on an early contractor involvement (ECI) basis, under which selected contractors submit methodologies and design proposals before one team is chosen to deliver the construction works. Saudi Arabia's AI company Humain, owned by the Public Investment Fund (PIF), tendered the contract in May.

The infrastructure scope encompasses construction of a 380kV/132kV/33kV electrical distribution network, two substations with capacities of 500MVA and 200MVA, and a bulk supply point of 2,000MVA, along with water networks and fire protection systems. The project also includes a sewage treatment plant, wastewater network, stormwater systems, roads, underground cable and fibre optic networks, and landscaping works.

The development will occupy a 24-square-kilometre site in the Al-Saad area in east Riyadh, delivered in two phases across six plots, each with 1GW capacity. Humain is being supported by Canadian engineering firm Hatch, France's Egis, and US-based JLL.

Humain was launched in May last year to operate and invest across the AI value chain, building full-stack capabilities across next-generation data centres, hyper-performance infrastructure and cloud platforms, and advanced AI models, including Allam.

In May 2025, Humain signed preliminary deals with US chipmakers AMD and Nvidia to build multibillion-dollar advanced digital infrastructure in the kingdom. AMD committed to invest up to $10 billion to deploy 500MW of AI compute capacity in Saudi Arabia over the next five years.

In October 2025, PIF and Saudi Aramco signed a non-binding term sheet setting out key terms under which Aramco would acquire a minority stake in Humain, with PIF retaining majority ownership.
