Dammam-based construction firm Al-Yamama Company for Trading & Contracting has won a contract to develop infrastructure for a planned 6GW hyperscale artificial intelligence (AI) data centre campus in Riyadh.

The project will be delivered on an early contractor involvement (ECI) basis. Under the ECI process, selected contractors are required to submit methodologies and design proposals, after which one team will be selected to deliver the construction works.

Saudi Arabia’s AI company Humain, owned by the Public Investment Fund (PIF), tendered the contract in May, as MEED reported.

The scope of infrastructure work covers:

• Construction of 380kV/132kV/33kV electrical distribution network, two substations with a capacity of 500MVA and 200MVA, bulk supply point (2,000MVA)
• Water network and fire protection systems
• Sewage treatment plant and wastewater network
• Stormwater systems
• Roads
• Underground cable and fibre optic networks
• Landscaping works

The client is being supported by Canadian engineering firm Hatch, France’s Egis and US-based firm JLL.

The development will be built on a 24-square-kilometre site in the Al-Saad area in east Riyadh. It will be delivered in two phases across six plots, each with a capacity of 1GW.

Humain was launched in May last year to operate and invest across the AI value chain.

Humain is building full-stack AI capabilities across four core areas: next-generation data centres, hyper-performance infrastructure and cloud platforms, and advanced AI models, including Allam.

Also in May 2025, Humain signed preliminary deals with US chipmakers AMD and Nvidia to build multibillion-dollar advanced digital infrastructure in the kingdom.

AMD said it will invest up to $10bn 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.
