Qatar-based Mannai Corporation announced that its Saudi Arabian subsidiary, Mannai IT KSA, secured a major engineering contract for a landmark Riyadh Giga-Project development.

Primary engineering procurement contractor China Harbour Engineering Company awarded the sub-contract package to deliver integrated mechanical, electrical, public health, and smart building technology infrastructure across the master plan.

This flagship Saudi capital contract accelerates nationwide infrastructure delivery frameworks, mirroring regional public-private partnership models seen in the Wasel Al-Haram Project: Saudi Arabia Signs $1.5B Mecca Transport PPP, which established multi-billion-dollar transit concessions across western Saudi Arabia.

Specialized engineering crews will execute the complete mechanical and technology scope over a fast-tracked two-year installation program.

Project directors structured the package to combine traditional building services with intelligent digital infrastructure.

Delivering MEP systems alongside smart building technology under a single contractual package reduces operational interface risks across complex urban sites.

Engineering Scope and Technology Systems for Riyadh Giga-Project

Technical teams designed the installation program to support high-density commercial, cultural, and residential facilities.

The integrated delivery framework establishes future-ready digital platforms while optimizing energy distribution across the urban district.

• Complete Mechanical and Electrical Installation: Engineering units will deploy high-efficiency HVAC networks, heavy electrical sub-stations, and primary power distribution grids.
• Integrated Public Health Systems: Specialized plumbing contractors will install advanced water treatment, greywater recycling, and municipal drainage networks.
• Smart Building Infrastructure: Technology integration specialists will implement Internet-of-Things automation, fiber communication backbones, and central data monitoring systems.

Engineers from Mannai Corporation will leverage experience gained from delivering mission-critical technology networks across major regional sporting and transport venues. Systems integration will meet stringent environmental performance criteria aligned with national building standards.

Execution Strategy and Delivery Milestones for Riyadh Giga-Project

China Harbour Engineering Company and Mannai IT KSA finalized the contract terms during an executive signing ceremony in Saudi Arabia.

The joint project office will coordinate engineering sub-mittals, equipment procurement, and site logistics to maintain the strict two-year construction timeline.

• Procurement and Detailed Design Mobilization: Technical teams finalize MEP schematics and issue long-lead equipment purchase orders for heavy HVAC units and smart servers.
• Rough-In and Structural Installation Phase: Site crews embed conduit networks, riser piping, and primary electrical cabling as civil construction advances.
• Smart Systems Integration and Commissioning: Technicians configure central building automation software, complete hydraulic balancing, and execute full operational testing.

The project supports broader urban transformation objectives established under Saudi Vision 2030. Expanding high-tech MEP infrastructure builds local engineering capacity while driving sustainable urban growth across the capital city.
