Expo 2030 Riyadh Company has awarded two further main utilities and infrastructure works packages to Al Yamama Company, extending buried services and site preparation across the six million square metre exhibition ground north of the Saudi capital.
The awards follow the first main utilities and civil works package, which went to Nesma & Partners in December, earlier than the organiser had originally planned. That contract covers around 50km of infrastructure networks: water and sewage systems, electrical and communications networks, and electric-vehicle charging infrastructure. Construction under it is already under way, and the Al Yamama packages build directly on it.
The organiser has described a phased approach in which infrastructure, buildings and public spaces advance in sequence through 2026 and into early 2027. Main site construction is expected to break ground in the third quarter of this year.
Front-loading the services is not a stylistic preference. A world expo has an opening date that cannot move, and its critical path runs through the plots rather than the permanent buildings. Riyadh has committed to hosting 197 nations and 29 organisations, each of which designs, procures and builds its own pavilion on its own programme, with its own contractors and its own delays. Those participants cannot start until the host hands over a serviced plot with power, water, drainage and communications already terminated at the boundary. Every week of slippage in the utilities is a week compounded across nearly 200 independent construction programmes.
That is why the first package was pulled forward rather than tendered on the original timetable, and why the follow-on scopes have gone out before the main buildings are procured. The site is planned around five districts and the organiser expects more than 42 million visits across the event.
Both contractors are Saudi. Nesma & Partners is one of the larger domestic contractors, with a background in industrial and infrastructure work rather than showpiece architecture, and Al Yamama Company is a long-established Riyadh civils and building contractor. For a client whose principal risk is schedule rather than novelty, that is a rational selection: deep utilities work rewards local mobilisation, established subcontractor relationships and familiarity with municipal approvals far more than it rewards international design credentials. It also sits comfortably with the local-content requirements now attached to Public Investment Fund-linked procurement.
The expo site is one of several very large programmes running concurrently in Riyadh. Diriyah has awarded more than $29bn of construction contracts, New Murabba has finished excavation and foundations for the Mukaab and expects to procure the superstructure in 2027, and King Salman International Airport produced one of the largest single awards of 2025 at about SR20.63bn for six parallel runways. Expo 2030 is the one among them with a fixed, externally set opening date, which is increasingly making it the pacing item for infrastructure delivery in the capital — and the reason contractors are watching its award schedule as a proxy for when labour and plant will be tightest.
What has not yet been let is the visible part: the permanent structures, the pavilion shells the host provides, and the public realm. Those packages will reach the market against a schedule that is now, by the organiser's own sequencing, running ahead of where it expected to be.
