Expo 2030 Riyadh construction gathers pace

14 July 2026

 

Construction activity at the Expo 2030 Riyadh site is accelerating, with Expo Riyadh 2030 Company (ERC) moving to award its first major vertical contracts and advancing infrastructure works across a programme that will eventually require between 50,000 and 70,000 workers at peak.

Saudi Arabia’s first World Expo runs from 1 October 2030 to 31 March 2031. Riyadh was awarded the hosting rights in November 2023, winning the vote in the first round, and the event is projected to attract more than 40 million visits over its six months. Beyond the event itself, the project carries significant economic weight: ERC, wholly owned by the Public Investment Fund (PIF), expects the construction phase and legacy development to contribute around $64bn to Saudi GDP and generate approximately 171,000 direct and indirect jobs, with the live event contributing a further $5.6bn.

The masterplan covers 6 million square metres to the north of Riyadh, adjacent to the future King Salman International airport. After the event closes, ERC plans to transform the site into a global village combining retail, food and beverage and an international residential community – meaning every asset being built now is being designed with its post-Expo purpose in mind.

Infrastructure works under way

The earliest works on site – bulk earthworks including cut, fill and levelling – have been completed by local contractor Binyah, with millions of cubic metres of material moved to bring the site to design level.

The programme has now moved into utility infrastructure, which has been split into two packages. Nesma is constructing the primary utility networks – the main corridor running around the site carrying high-voltage power lines, water mains, sewerage and communications – while Al-Yamama is delivering the secondary networks that bring services into the central event area, with construction expected to commence this month.

Power has been a priority. ERC has worked with the Saudi electricity sector since 2025 to develop the site’s demand profile, and an agreement for permanent supply has been signed. Design and procurement of the main substation and primary power infrastructure are under way, with a contract award expected within weeks and full permanent power – at a capacity of 400MW – targeted approximately 18 months ahead of the event.

An initial 25MW supply to power site operations and support testing and commissioning is already installed and ready to be energised.

On water, ERC is finalising an agreement with the Royal Commission for Riyadh City (RCRC), the Saudi Water Authority and the National Water Company, with an announcement expected in Q3 and construction targeted to start in 2027.

Transport and connectivity

With more than 42 million visits anticipated over the six-month event, transport connectivity is treated as central to the project’s success. ERC is working with RCRC on a mobility plan that covers several modes. Two road enhancement projects around the airport and along King Salman Road are expected to be announced shortly, increasing capacity on the main arteries approaching the site.

A dedicated Expo metro station on Riyadh Metro Line 4 – which connects the airport to the city centre – will be built within the site boundary, forming the first stop from the airport towards Riyadh, and providing a direct link for international arrivals.

A park-and-ride programme using dedicated bus lanes will serve domestic visitors parking at locations across the city.

A hotel within the fenced Expo site is also nearing contract, with a design agreement close to signature. ERC says the intention is to give guests staying on site “the full experience from early morning when the gates open until late at night when the gates close” – an offer it expects will prove particularly popular with international visitors.

Pavilions and vertical assets

The Expo's masterplan is organised around five districts, each echoing one of the event’s sub-themes under its overarching theme of Foresight for Tomorrow: planet, people, technology, collaboration and culture. ERC is responsible for delivering a signature pavilion in each district, plus an iconic structure in the Global Collaboration district and a convention centre intended to serve both the event and Riyadh’s long-term conference market.

The Kingdom of Saudi Arabia (KSA) Pavilion, one of the centrepieces of the event, is also under ERC’s delivery responsibility. Design work is progressing across all these assets with engineering firms taking concepts through to schematic and detailed design.

For international participating countries, this edition of the Expo marks a significant departure from previous editions. Rather than grouping lower-income countries into shared halls, all participants will have their own national pavilion.

“In this edition, we are following the ‘one nation, one pavilion’ model, whereby each country has its own pavilion, and we have a dedicated budget to help up to 100 eligible countries deliver those pavilions,” says Murad Al-Sayed, ERC’s chief delivery officer.

Contracting strategy

The contracting approach for vertical assets is being calibrated to the complexity of each building. Less complex assets will be procured on a design-and-build basis.

For the most complex – the KSA Pavilion and the iconic structure – ERC is using a two-stage model, separating enabling works and substructure from the main contract. This allows construction to begin on site while the main package is finalised and brings contractors into the design process earlier.

“We are adopting different contracting strategies depending on the asset – its size, complexity and anticipated construction duration,” Al-Sayed says.

For the KSA Pavilion, enabling and substructure works are already in the market, with an award targeted in Q3, allowing construction to start before the main contract – for which nine tier-one contractors, local and international, have been invited to bid – is awarded towards the end of the year. Packages for the remaining signature pavilions are expected to follow later this year and into 2027.

On commercial terms, ERC is favouring lump-sum contracts where design maturity allows, with provisional sum or remeasurement provisions used where elements remain in development. A final public realm package, covering site-wide finishing works, remains under design and is expected to be tendered in 2026, sequenced deliberately to be installed last and once only ahead of the event.

Bidding appetite from the market has been strong. ERC says all tenders issued to date have attracted healthy numbers of qualified bids, reflecting a contracting market that has eased over the past 18 months as several gigaprojects elsewhere in the kingdom have reached completion or had their timelines revised.

Programme and supply chain

ERC is targeting completion of major construction by the end of 2029, leaving six to nine months for finishing, snagging and operational testing. To ease the build programme for international participants, ERC is making plots available up to 36 months before the event – around nine to 12 months longer than the industry norm – giving countries more schedule float to complete their pavilions.

On the supply chain, ERC is leaning heavily on local manufacturers for current infrastructure work, covering piping, cabling, electrical equipment and bulk materials. As construction moves above ground and international participants begin work on their pavilions from 2027 onwards, ERC will make its database of prequalified local contractors, suppliers and consultants available to them through a dedicated one-stop shop – a registration exercise already under way and expected to remain open until the event itself.

  • SAR tenders design review consultancy for GCC rail link

    18 September 2026

     

    Register for MEED’s 14-day trial access 

    Saudi Arabia Railways (SAR) has issued a request for proposals (RFP) for a design management and review consultant to oversee engineering works on the GCC railway network, the latest step in advancing the long-delayed regional rail link.

    The RFP was issued on 9 September, with a submission deadline of 18 October.

    The tender seeks a consultant to manage, audit and verify deliverables produced by SAR's separately appointed design services consultant, rather than carry out the design itself. The tendering for the design services consultancy is currently in progress.

    Construction will be tendered separately through competitive bidding once designs are approved.

    The GCC railway will run for about 672 kilometres (km) inside Saudi Arabia, linking the kingdom's existing network to Kuwait, Qatar, the UAE and Bahrain, with four sections of about 141km, 200km, 151km and 21km, respectively.

    The line is planned as a single-track, non-electrified corridor for mixed freight and passenger traffic, with a maximum axle load of 32.4 tonnes and passing loops for bidirectional working.

    The appointed consultant will develop a design management and review plan covering governance, interdisciplinary coordination and stage-gate approvals, and will issue formal review and audit reports against SAR's requirements and international standards.

    The scope also covers stakeholder engagement, interface management and oversight of land acquisition activity tied to the design consultant's land acquisition plan.

    Key design stages are expected to take about 16 months: four months for concept design, six for preliminary design and six for issued-for-construction design, each with four weeks of contingency.

    SAR has asked bidders to mobilise a core team from day one. These must include a project director, engineering and design manager, stakeholder manager and lead document controller, all based at SAR's offices, with minimum experience thresholds ranging from three years for junior operators up to 25 years, including 15 in rail, for the project director role.

    GCC railway line

    Under the overall plan, the railway will run from Kuwait, pass through Dammam in Saudi Arabia, reach Bahrain via a planned causeway, and continue from Dammam to Qatar, the UAE and, ultimately, Muscat via Sohar in Oman. The railway is reported to cover about 2,186km in total.

    The route length within each member state is as follows:

    • UAE – 684km
    • Saudi Arabia – 672km
    • Oman – 306km
    • Qatar – 283km
    • Kuwait – 145km
    • Bahrain – 36km

    The railway is designed for passenger trains travelling at 220 kilometres an hour (km/h) and freight trains operating at 80km/h–120km/h.

    With high levels of project activity, governments in spending mode and renewed cooperation under the Al-Ula Declaration, the latest efforts to restart the GCC railway project may make more progress than previous attempts. If completed, the railway could prove transformational for a region that is globally connected but still divided by national borders.

  • Tender issued for Libyan gas project

    17 September 2026

    An invitation to bid has been issued for a contract to conduct environmental assessments for the project to expand the Mellitah oil and gas complex in Libya.

    The bid submission deadline is 2pm today (17 September) Libyan time.

    The scope of the project includes provision of:

    • An environmental baseline study (EBS)
    • An environmental impact assessment (EIA)
    • An environmental management plan (EMP)

    The client is Mellitah Oil & Gas (MOG), which is a joint venture of Italy’s Eni and Libya’s National Oil Corporation (NOC).

    MOG is based in Tripoli and operates both onshore and offshore oil and gas facilities.

    The joint venture owns and operates six major oil and gas fields across the North African country.

    According to the tender documents, the company that is awarded the contract will need to prepare environmental management measures in compliance with:

    • Libyan environmental legislation
    • Ministry of Environment requirements
    • NOC environmental guidelines
    • Applicable international environmental standards and best practices

    The expansion of the Mellitah oil and gas complex is part of a project estimated to be worth $8bn.

    The wider project is known as the Mellitah Complex Expansion & CO2 Management Integrated Development Project.

    It has six main packages:

    • Onshore package
    • Offshore Structure A
    • Offshore Structure E
    • Subsea pipeline package
    • Site preparation work
    • Carbon capture and storage facility

    Security issues and political instability have been a major problem for Libya’s oil and gas sector since the country’s civil war started in 2011.

    Earlier this month, the Mellitah oil and gas complex was forced to shut down temporarily due to a protest over deteriorating public services.

    The existing onshore complex includes housing, processing units, storage facilities and export facilities.

    It also serves as the launch point for the Greenstream pipeline, which delivers Libyan gas directly to Italy.

    The planned expansion of the complex will involve:

    • Construction of a new fourth gas processing train
    • Construction of a third condensate train
    • Construction of a third natural gas liquids fractionation train
    • Construction of a fourth sulphur recovery unit train
    • Installation of a hydrogen sulphide enrichment unit
    • Installation of a sulphur recovery unit
    • Construction of other associated facilities

    The Mellitah complex is located about 100 kilometres west of Tripoli and is a key energy facility in the west of the country.

  • Nakheel awards $218m Dubai Islands buildings deal

    17 September 2026

    Register for MEED’s 14-day trial access 

    Dubai-based developer Nakheel, now part of Dubai Holding, has awarded a main construction contract worth more than AED800m ($218m) for phases one and three of Bay Grove Residences at Dubai Islands.

    The contract was awarded to the local firm Metac General Contracting Company.

    It covers the construction of 537 apartments, comprising one- to four-bedroom units, across seven residential buildings.

    Phase one includes 296 units in four buildings, while phase three comprises 241 units across three buildings.

    The works are scheduled for completion in late 2028.

    Bay Grove Residences will ultimately comprise 1,154 homes across 15 buildings. Planning is under way for the remaining 617 homes in phases two and four, with further contract awards expected.

    In August last year, Nakheel awarded a AED2.6bn ($708m) contract to Abu Dhabi-based Fibrex Contracting to build the Bay Villas project at Dubai Islands. The contract includes constructing 636 villas.

    In April this year, another AED527m ($143m) contract was awarded to local firm Al-Nasr Contracting Company to construct the primary infrastructure and utilities works on Island B at the development.

    The Dubai Islands development consists of five islands spanning 18.6 square kilometres. It features more than 59 kilometres (km) of waterfront and 20km of beaches, as well as parks, golf courses, promenades and cycling paths.

    The offshore island project gained renewed momentum in 2022, when Nakheel unveiled a new masterplan and rebranded it as Dubai Islands.

    The reclaimed islands were originally part of the Palm Deira project, which was partially completed before being put on hold in 2008.

  • Neom tenders Oxagon highway contract

    17 September 2026

     

    Saudi Arabia’s Neom has tendered a design-and-build contract covering permanent upgrade works on Highway 55 in the kingdom’s Oxagon region.

    The first phase of the project includes constructing 14 kilometres of road, with two lanes in each direction. It also covers one bridge and three interchanges.

    The project duration is 22 months.

    Contractors have been given until 21 September to submit their proposals.

    Highway 55 connects the Red Sea coast with the mainland in northwestern Saudi Arabia. It is currently the only road providing north-south connectivity between Duba and the Neom region.

    MEED exclusively reported in August 2025 that contractors had submitted responses to the expressions of interest notice that Neom had issued earlier that month.

    The project is expected to support the movement of cargo vehicles from Duba Port to other parts of the country and the wider region.

    Neom tested a pilot initiative last year by handling a shipment that travelled from Cairo via the Port of Safaga, across the Red Sea to the Port of Neom, and then inland to Erbil, Iraq.

    In a statement, Neom said: “The shipment travelled through an intermodal corridor spanning over 900 kilometres, marking a significant milestone in the kingdom’s transformation into a regional and global logistics hub.”

    The Port of Neom is located on the Red Sea near the Arar border, a key entry point into Iraq.
