Saudi Tender Watch — Issue 3

Priority action

Water-sector companies should assess the Eastern A Cluster immediately. Bids for the approximately $180m package are due on 30 September 2026; direct international eligibility should be confirmed with NWC before committing bid resources.

Eastern A Cluster — LTOM14

National Water Company

Who should pursue — wastewater operators, water EPC contractors, treatment-technology companies, O&M specialists, equipment suppliers and infrastructure financiers.

NWC’s Eastern A Cluster covers rehabilitation and upgrading of six sewage treatment plants. Expansion of Al-Jarodia STP by 30,000 cubic metres a day would lift combined treatment capacity from about 263,000 to 293,000 cubic metres a day.

At least three Saudi contractors are reported to be preparing bids. The identified field does not establish a local-only restriction, so foreign-bidder access remains unconfirmed. International companies should verify direct eligibility and, where appropriate, assess technology, subcontracting or consortium routes.

Why it matters — this is the week’s clearest live opportunity, combining a substantial contract value with a defined September deadline and a wider NWC programme that has already attracted international participants.

Prince Naif International Airport PPP

Matarat Holding · National Center for Privatization & PPP

Who should pursue — airport systems and equipment suppliers, EPC and specialist contractors, engineering consultants, infrastructure lenders, advisers and potential partners to the six qualified groups.

Five consortia and India’s GMR Airports have qualified for the long-term redevelopment of Prince Naif bin Abdulaziz International Airport. The field includes airport and infrastructure groups from Türkiye, France, Oman, Ireland, India, Bahrain and the UAE alongside Saudi partners.

The scope includes the passenger terminal and associated airside infrastructure under a design-finance-construction-operations-maintenance-transfer structure. The prime bidder field is fixed, but the procurement phase should create substantial downstream financing, systems, consultancy and supply-chain opportunities.

Why it matters — the qualification milestone turns a broad market approach into six identifiable bidding groups that suppliers, banks and advisers can target before final bids and financing structures are completed.

Land-port residential PPP

Zakat, Tax and Customs Authority · NCP

Who should pursue — PPP contractors, residential builders, facilities-management groups, building-systems suppliers, lenders and advisers.

ZATCA and NCP have selected preferred bidders for two packages covering residential buildings and associated facilities at nine Saudi land ports. Saudi Arabian Trading & Construction Company leads Package 1, while Bahrain-headquartered Lamar Holding is preferred for Package 2.

The DBFOMT structure covers new construction, management and rehabilitation over a 23-year term. The prime investment competition is advanced, but the preferred-bidder stage creates clearer downstream targets for construction, FM, systems, financing and specialist supply.

Why it matters — Lamar’s selection confirms cross-border participation and gives GCC suppliers and financiers a defined route into a multi-site Saudi PPP programme.

Northern Cluster STPs — LTOM10

National Water Company

Who should pursue — treatment-equipment suppliers, specialist contractors, technology providers, imported-equipment vendors and financing/service companies.

NWC has signed a 15-year LTOM contract with a Saudi-Chinese consortium covering rehabilitation, operation and maintenance of nine sewage treatment plants in Hail, Qassim, Al-Jouf and the Northern Borders.

The plants have combined design capacity exceeding 337,000 cubic metres a day. The programme includes rehabilitation and upgrades before long-term operation, creating continuing demand for treatment technology, equipment, specialist works and operating services.

Why it matters — the award confirms international participation in NWC’s LTOM model and opens a sizeable delivery-stage supply chain around a contract worth more than $348m.

Expo 2030 Riyadh metro station

Royal Commission for Riyadh City

Who should pursue — rail systems suppliers, station MEP and fit-out specialists, civil subcontractors, testing firms and project-service providers.

RCRC has awarded Freyssinet Saudi Arabia the design-and-build contract for a new Riyadh Metro station serving the Expo 2030 site in the north of the capital. The station will sit on Line 4, the Yellow Line.

The station forms part of a wider Expo delivery programme where infrastructure and vertical construction activity is accelerating. The principal competition is closed, but station delivery should create specialist packages across civil works, MEP, systems, fit-out and testing.

Why it matters — the station connects the Expo site directly into Riyadh’s metro network and provides a focused downstream procurement opportunity within a much larger event-infrastructure programme.

Oxagon AI data-centre development

HUMAIN · DataVolt · Oxagon

Who should pursue — power and cooling suppliers, MEP contractors, fibre and network providers, modular construction firms, data-centre equipment vendors and technology financiers.

HUMAIN and DataVolt have begun construction of the first 100MW of AI-ready data-centre capacity at Oxagon. The initial build forms part of a 360MW phase within a campus ultimately planned to reach as much as 1.5GW.

The first 100MW is intended for high-density AI and cloud workloads and is expected to become available in 2028. The current package value has not been disclosed, so the opportunity is best viewed through the delivery supply chain rather than as an open prime tender.

Why it matters — construction start gives suppliers a firmer timetable for power, cooling, network, modular and specialist MEP procurement at one of Saudi Arabia’s largest planned digital-infrastructure campuses.

Pipeline watch

LTOM12: NWC’s North Western B Cluster is moving towards award after financial bids were opened. The package covers seven STPs with combined capacity of about 162,000 cubic metres a day.

LTOM16: NWC’s Central Cluster is expected to be the next package tendered, potentially in November. The original scope covers 14 STPs with total capacity of about 153,000 cubic metres a day.

Taif International Airport: procurement remains under way for the new airport PPP, including terminal, airside, utilities, parking and access-road infrastructure.

Hail Airport: an expansion award has been reported, but the contract value remains undisclosed. Track the delivery phase for specialist aviation, building-services and equipment packages.

Before pursuing an opportunity

Confirm tender status and eligibility with the procuring organisation. Check Saudi registration, RHQ applicability, local content, prequalification, classification, Saudisation and joint-venture requirements. “Eligibility unconfirmed” means the public material did not establish foreign-bidder access.
