The most useful numbers at Shaping Mega Projects 2026, the delivery summit that opened Monday at The Venue in ROSHN’s SEDRA community in Riyadh, came from the organizers’ own ledger. Roughly $130 billion of giga-project contracts have been awarded. Close to $200 billion more is moving through procurement. The larger half of the program has yet to be bought, and that single ratio organizes the agenda, the anxieties and the opportunities of the three days that follow.
The summit, in its fourth edition, runs through Wednesday with more than 300 delegates from the developers, contractors, investors and delivery partners doing the buying and building: Diriyah Company, Red Sea Global, ROSHN, Qiddiya, New Murabba, Soudah Development, the King Salman Park Foundation and their peers. The program tells you what its participants think is hard. Sessions on capital mobilization and procurement flank a new contractors’ leadership forum on capacity building, digital delivery, industrial localization and supply chain resilience. None of those topics belongs to the announcement phase of a construction program. All of them belong to the phase where invoices are issued.
The developers arrived with operating numbers rather than renderings. Diriyah Company cited SR16 billion ($4.3 billion) in sales to date and close to six million visitors to Bujairi Terrace. Red Sea Global’s airport is receiving scheduled flights. Sales, visitor counts and cost per delivered unit are business metrics, and their appearance on conference slides marks where the program now sits: early assets in operation and reporting revenue, while the next, larger tranche moves through tendering.
Power and water run underneath all of it. MEED’s power and water desk put the seventh round of the National Renewable Energy Program at 5,300 megawatts of solar and wind capacity, adding to the roughly 2,000 megawatts of battery storage agreements Saudi Power Procurement Co. signed in August. Demand is diversifying beneath the projects: population growth, the megaprojects themselves and a data center buildout that raises requirements for electricity and water at once. Desalinated water needs transmission as much as production, and wastewater needs treatment capacity to match the households being built. Each is its own procurement pipeline.
The friction was named plainly: contract awards in water and power have run slower than the demand curve. That is the delivery phase’s characteristic risk. In the announcement phase of a national construction program, the scarce input is credibility. In the delivery phase it is absorption: contractor balance sheets, skilled labor, grid equipment, cement and steel arriving in sequence. A $200 billion procurement queue converts into assets only at the pace the supply chain can take the orders, which is why localization and supplier development have moved from policy language into tender criteria.
The second day turns to executing at scale, with Expo 2030 Riyadh, Sports Boulevard, Jeddah Economic City and Jeddah Tower on the program. Expo 2030 carries a fixed international deadline, which makes it the schedule the rest of the Riyadh pipeline gets sequenced around. Fixed-date projects take priority in any capacity constrained system, and every contractor in the hall knows it.
The number to follow is the ratio itself. A maturing program is one in which the awarded figure closes on the procurement figure quarter by quarter, without the award cadence in power and water falling further behind the demand it serves. The summit’s working estimate says the Kingdom’s construction decade is nearer its beginning than its middle. The order books will say when that changes.
