Contractors prepare Oxagon tunnelling bids

30 May 2023

 

Contractors are preparing to submit bids in June for a contract to build tunnels connecting the offshore elements of the Oxagon industrial city at Neom to the mainland.

The design-and-build contract involves digging a 6.5-metre-diameter tunnel using a tunnel boring machine (TBM) under the sea that will link the Neom Connector with the offshore elements of Oxagon port. It will house utilities including water pipelines, fibre optic cables and electricity cables.

Prospective bidders for the contract include:

  • Abuljadayel Company (local)
  • Bessac (France)
  • Binladin Contracting (local)
  • Daewoo (South Korea)
  • Dogus (Turkey)
  • Hassan Allam (Egypt)
  • Petrojet (Egypt)
  • Saudi Pan Kingdom Company (Sapac)
  • Shanghai Tunnel Engineering Company (China)
  • Soletanche Bachy (France)

Crown Prince Mohammed bin Salman launched Oxagon in late 2021. It will include onshore elements as well as floating structures offshore. Construction works on the 48 square-kilometre, eight-sided industrial city have already started.

Port construction

Work is also under way for the industrial city’s port, with Neom tendering a contract to complete the next phase of the Duba port expansion at Oxagon industrial city.

The prospective bidders are Belgium’s Deme with Greece’s Archirodon; Van Oord of the Netherlands with South Korea’s Hyundai Engineering & Construction; a Belgian joint venture of Jan de Nul and Besix; Netherlands-based Boskalis with France’s Soletanche Bachy; and China Harbour Engineering Company.

The tender for the project’s second phase follows the award of a contract to deliver the first phase of the port expansion. A team of Boskalis, Besix and the local Modern Building Leaders (MBL) was awarded that estimated SR3bn ($800m) contract in mid-January.

The scope of the Duba port expansion package includes excavation and dredging, revetments for channel widening, demolition, container terminal quay expansion and earthworks, in addition to the development of a flexible quay, a roll-on/roll-off (RoRo) berth and quay walls to a marine services berth and a coast guard facility.

Jacobs is the main design consultant with Moffatt & Nichol, IGO and Trent as the main subconsultants.

Port operations

Several crane and container equipment contracts have been awarded to Saudi Liebherr Company and Shanghai Zhenhua Heavy Industries Company (ZPMC).

Saudi Liebherr was awarded contracts for 10 mobile harbour cranes for SR200m.

ZPMC has been awarded contracts for 10 ship-to-shore gantry cranes, 30 electric rubber-tiered gantry cranes and six automated rail-mounted gantry cranes for over SR1bn. ZPMC will work with Siemens Europe to deliver the automation components. 

An expanded Duba port is a critical component of Oxagon and the broader Neom development, as it will allow greater volumes of materials to be imported for the project. With an expected investment value of $500bn, Neom is the largest programme of construction work in the world.

Neom says the first container terminal will be operational by the beginning of 2025.

The management of Duba port was transferred from national maritime regulator Mawani to Neom in 2022.

    Syria’s Ministry of Energy has invited expressions of interest (EoIs) for the development of the Halabiyeh-Zalabiyeh dam project on the Euphrates River.

    The project has an indicative total cost of $1.16bn, according to the ministry’s EoI document. This includes $433.7m for the dam and hydropower plant and $729.6m for the pumped-storage power plant (PSP). 

    The scheme includes an 81MW hydroelectric power plant and a pumped-storage facility with a capacity of up to 1,200MW. The project will also include the construction of the dam and associated water-storage infrastructure. 

    The ministry seeks interest from qualified local and international companies, investors and other entities. Interested parties can participate in studies, design, financing, construction, and operation and maintenance of the project. 

    The ministry is considering several potential development structures, including build-own-operate-transfer, build-operate-transfer and public-private partnership models, as well as an engineering, procurement and construction (EPC) structure. It has said it is also open to proposals covering consultancy and financing services.

    The EoI covers several stages, including pre-feasibility and feasibility studies, financing and bankability studies, detailed and executive design, EPC execution, and operation and maintenance.

    The technical specifications envisage a 23-metre-high dam with a reservoir storage capacity of about 219 million cubic metres.

    The hydropower plant will have three generating units, while the 1,200MW PSP will have 3.5 hours of storage capacity and four reversible units.

    The deadline for submitting EoIs is 10 November, with enquiries accepted until 26 October.

  • Arada launches UAE construction arm with Roberts

    7 October 2026

    Register for MEED’s 14-day trial access 

    UAE developer Arada has integrated Australian contractor Roberts into the UAE market as part of its wider business strategy.

    Arada acquired Roberts in 2025 after entering the Australian market. The tier-one contractor delivers projects in the healthcare, education, commercial, residential, hospitality, industrial, life sciences and defence sectors.

    At the time of the acquisition, Arada said it planned to invest about $20m in Roberts. The investment is intended to give the developer greater control over the delivery of its Australian projects and support Roberts’ expansion into markets including the UAE.

    Arada has said it could invest up to $100m in Roberts’ expansion into new sectors and markets. The company is targeting $1bn in annual revenue from Roberts by 2028.

    Roberts has established a UAE office, with a head office team already in place. Arada said the contractor’s capabilities will support the delivery of its high-rise residential and social infrastructure projects.

    The contractor’s first UAE project will be phase two of Arada Central Business District, a commercial development within Aljada in Sharjah. Arada is developing the AED35bn ($9.5bn) mixed-use project.

    Roberts is also providing preconstruction services for several Arada projects in Dubai and Sharjah, ahead of starting site work.

  • Expo Riyadh sets October deadline for Saudi Arabia pavilion

    7 October 2026

     

    Expo 2030 Riyadh Company (ERC), tasked with delivering the Expo 2030 Riyadh venue, has set a deadline of 25 October for bids for a contract to build the Saudi Arabia pavilion.

    The tender was issued on 19 May, with an initial bid submission deadline of 26 August.

    The pavilion is a major asset located within the KSA District on the eastern side of the Expo 2030 Riyadh masterplan, in the Loop of Nations district.

    Construction activity at the Expo site is accelerating, with Riyadh moving to award its first major vertical contracts and advancing infrastructure works across the programme.

    Last month, MEED reported that ERC had received contractor interest on 14 September for a contract to design and build a convention centre in the site’s Collaboration District.

    ERC also tendered a contract to deliver the Souq areas within the Expo site, as MEED exclusively reported on 8 September.

    These areas are divided into five precincts, with a total development area of about 300,000 square metres.

    Also in September, Saudi Arabia’s Royal Commission for Riyadh City awarded a design-and-build contract to construct a new metro station serving the Expo 2030 site.

    In April, ERC awarded two contracts for the next phase of infrastructure works at the site to local firm Al-Yamama Company.

    The scope covered the construction of road networks and infrastructure for water, sewage, electricity, telecommunications and electric vehicle (EV) charging.

    These awards followed ERC’s January award of an estimated SR1bn ($267m) contract for initial infrastructure works at the site to local firm Nesma & Partners.

    That scope covered about 50 kilometres of integrated infrastructure networks, including internal roads and essential utilities such as water, sewage, electrical and communications systems, as well as EV charging stations.

    The masterplan covers 6 square kilometres, making it one of the largest sites ever designated for a World Expo event. Situated north of the Saudi capital, the site will be near the future King Salman International airport and will provide direct access to Riyadh landmarks.

    The Public Investment Fund, Saudi Arabia’s sovereign wealth vehicle, launched ERC – a wholly owned subsidiary – in June 2025 to build and operate facilities for Expo 2030.

  • Kuwait on track to hit oil production target

    7 October 2026

    Kuwait is on track to meet its target of having 4 million barrels a day (b/d) of oil production capacity by 2035, according to Kuwait Petroleum Corporation (KPC) chief executive Shaikh Nawaf Al-Sabah.

    Al-Sabah also said Kuwait is on course to increase non-associated gas production to 2 billion cubic feet a day by 2040.

    His comments come amid an ongoing crisis in Kuwait’s oil and gas sector linked to the regional conflict that began when the US and Israel attacked Iran on 28 February.

    The subsequent war has significantly disrupted shipping through the Strait of Hormuz, which is a crucial export route for Kuwaiti crude oil.

    Kuwait is currently producing around 2 million b/d of oil, down from 2.6 million b/d before the US and Israel attack.

    Speaking at a conference in London, Al-Sabah said: “We have the capacity to go back up to our current maximum sustainable capacity of 3 million b/d, if we have the export routes available, and this comes down to the ability to move oil through the Strait.”

    KPC is investing $9bn-$10bn a year in capital expenditure to meet its oil and gas production goals, according to Al-Sabah.

    He said: “We are doing this because we recognise that it is our hydrocarbons that will be most in demand a decade from now, and two decades from now – in fact, for the rest of our lifetimes.”

    Project Seef

    KPC is pushing ahead with the Al-Seef project, which focuses on developing three large offshore oil discoveries, Al-Sabah said.

    The offshore fields are known as Nokhatha, Julaia and Jazza. The development was first announced in February this year, about two weeks before the US and Israel attack on Iran.

    Al-Sabah said KPC is continuing with the project and believes the three fields collectively hold more than 3 billion barrels of recoverable oil.

    He said: “We are asking international oil companies to partner with us to develop those resources under an operating services contract.

    “So, we’re moving ahead according to the exact same schedule that we had put together even before the war began.”

    Al-Sabah did not say which international oil companies KPC has approached to help develop the three offshore fields.

  • Roshn plans new flagship development in Riyadh

    7 October 2026

     

    Saudi developer Roshn Group plans to develop its next flagship scheme in north Riyadh, spanning an area of 13.7 square kilometres. 

    Roshn is looking to appoint lead design consultants to deliver detailed design, tender documentation and construction documents across the scheme, known as Plot 1.

    The scope covers all infrastructure, utilities, public realm works and site adaptation of Roshn’s residential prototypes, split across two work packages.

    Part 1 covers phases A, B and E, which collectively span about 7.8 million square metres (sq m) and will comprise 17,000 units.

    Part 2 includes phases C and D, which will span about 4.7 million sq m and comprise more than 15,000 units.

    The development is bordered by Expo 2030, King Abdulaziz Park, the Sports Innovation Lab Zone and the National Housing Company-developed Khozam district.

    It will be a residential-led mixed-use development, also featuring retail, offices, hospitality, education and civic facilities.

    Connectivity is a core plank of the masterplan, with two metro stations planned: one at the existing Line 4/proposed Line 7 interchange and another dedicated Line 7 stop. The scheme would also be served by the future Qiddiya high-speed rail and a possible King Salman Road diversion.

    Plot 1 builds on Roshn’s existing footprint in the capital, notably the multi-phase Sedra community, as the developer expands beyond single-family housing into mixed-use districts under its Roshn 3.0 strategy.

    Last month, Roshn Group announced that it had signed a preliminary agreement with Talaat Moustafa Group (TMG) Saudi, the local subsidiary of Egyptian developer Talaat Moustafa Group, to establish a joint venture to explore and develop a mixed-use project in Riyadh.

    Under the agreement, TMG will hold a 51% stake in the joint company, while Roshn Group will hold 49%.

    The agreement sets out a framework for the two groups to assess a potential partnership for the project’s phased development, which is planned as a residential-led, mixed-use community featuring retail, commercial, hospitality, leisure, healthcare and education facilities, alongside parks and public spaces.

    Roshn Group and TMG Saudi plan to conduct detailed master planning and develop the project’s business case.

    Preliminary studies indicate the development could include more than 55,000 residential units across all phases.

    Roshn Group did not disclose the exact project location in its announcement.

    As a Public Investment Fund-owned developer, Roshn remains a key vehicle for delivering Vision 2030’s housing programme, which targets 70% Saudi home ownership, alongside the kingdom’s wider quality-of-life and economic diversification agendas.
