Abu Dhabi’s ADQ completes Plenary 49% stake purchase

24 February 2025

Abu Dhabi-headquartered ADQ has completed the acquisition of a 49% stake in Australian infrastructure investor and developer Plenary Group.

The Abu Dhabi-based critical infrastructure-focused sovereign investor announced the planned acquisition in April last year,  including all shares owned at the time by the Canadian pension fund Caisse de Depot et Placement du Quebec.

The transaction marks the first major inbound investment from the UAE into an Australian company since the signing of the Australia-UAE Comprehensive Economic Partnership Agreement, ADQ said in a statement.

The investment significantly strengthens Plenary’s balance sheet, accelerating growth in key markets in Australia and New Zealand, including prospective projects such as Hobart Stadium, Brisbane 2032 Olympics infrastructure, energy transmission, social and affordable housing and transport infrastructure.

The investment also positions Plenary to expand its presence in other priority regions, including the Middle East, Asia, the UK, Ireland and Europe, said ADQ.

As part of the agreement, Plenary and ADQ have established a co-development and investment platform, Plenary Middle East, which will focus on public and social infrastructure opportunities in high-growth regions in the Middle East and Central Asia.

Plenary remains majority-owned and controlled by its Australian founders and senior management team, maintaining operational independence as it continues to develop and invest in long-term infrastructure and real assets.

Plenary, in partnership with other firms, has won several public-private partnership (PPP) contracts in the UAE since 2022.

A consortium comprising Belgium’s Besix and Plenary won a contract to develop the Zayed Schools PPP project in May of that year. The scheme involved the development of three schools with a capacity of over 5,000 students from kindergarten to grade 12. Construction works on the project were completed last year.

In July 2024, the Abu Dhabi Investment Office (Adio) appointed a team of Plenary, Besix and the local Mazrui International for a contract to develop and operate a 3,250-bed student accommodation complex and associated facilities at Khalifa University in Abu Dhabi. 

Plenary is also part of a consortium that is understood to be planning to bid for the first two packages of the $22bn Dubai Strategic Sewerage Tunnels project.  

Another Australian infrastructure developer and investor is also expected to enter the Middle East region.

MEED recently reported that PPP projects in the Middle East will be a key focus for Sydney-headquartered infrastructure developer and investor Capella Capital, following its acquisition by Japanese infrastructure investor Sojitz in January this year.

  • Firms prepare Hudayriat East PPP tunnels advisory bids

    25 June 2026

     

    Abu Dhabi’s Modon Infrastructure, formerly Gridora, has tendered a contract for technical advisory services for the construction of two underwater tunnels connecting the eastern side of Hudayriat Island with mainland Abu Dhabi.

    Consultants have until 26 June to submit their proposals.

    The project includes the construction of a 4.8-kilometre (km) highway, with four lanes in each direction, connecting Hudayriat Island to Mussafah 8th Street.

    The project will be delivered on a public-private partnership (PPP) basis in coordination with the Abu Dhabi Department of Municipalities and Transport and the Abu Dhabi Investment Office.

    The contract term is expected to be 25 years.

    The latest infrastructure development in Abu Dhabi follows Modon Infrastructure’s invitation in May for firms to register for the next phase of Abu Dhabi’s Mid Island Parkway Project (MIPP), which will also be developed on a PPP basis.

    Modon Infrastructure will act as the lead developer, holding the majority equity stake in the project company. It will award the engineering, procurement and construction contract, as well as the operations and maintenance services and advisory appointments.

    The second phase of the MIPP involves the construction of about 11km of highways, including a mix of three-, four- and five-lane sections. The highways will connect the Um-Yifeenah, Al-Jubail, Al-Sammaliyyah and Sas Al-Nakhl islands to Khalifa City and the E10 road.

    The scope also covers the construction of three interchanges: the E20, E10 and Dumbbell interchanges on Al-Sammaliyyah Island.

    The project includes several major structures, such as the E20 interchange, which will feature cast-in-place box-girder and void-slab bridges, and the E10 interchange with cast-in-place box-girder bridges. It also includes I-girder bridges between Raha Beach West and Sas Al-Nakhl Island, as well as a causeway at Sas Al-Nakhl Island.

    Further key elements include a cast-in-place balanced cantilever bridge between Sas Al-Nakhl Island and Al-Sammaliyyah Island; a tunnel between Al-Sammaliyyah Island and Bilrimaid Island; and a cut-and-cover (open) tunnel on Bilrimaid Island. The project will be completed with another tunnel connecting Bilrimaid Island to Um-Yifeenah Island.

  • Red Sea Global tenders King Salman Bay construction work

    25 June 2026

     

    Saudi gigaproject developer Red Sea Global (RSG) has tendered a contract inviting firms to undertake marine infrastructure works at King Salman Bay on the Red Sea coast, north of Jeddah.

    The scope includes dredging and earthworks, as well as quay wall and edge protection works spanning about 11 kilometres.

    The bid submission deadline is 31 July.

    King Salman Bay is expected to be a waterfront development aimed at reshaping the city’s northern Red Sea frontage into a mixed-use destination, anchored by public-realm improvements and leisure-led development.

    The update follows RSG’s award of an estimated SR100m ($27m) contract to construct a solid waste management centre at its Red Sea Project. The scope includes four buildings: a material recycling facility, a transfer station, an administration building and a vehicle maintenance building.

    In October last year, MEED reported that RSG had secured a SR6.5bn ($1.7bn) credit facility to further develop Amaala, its luxury tourism destination on Saudi Arabia’s northwestern Red Sea coast.

    According to an official statement, “The funding is led by Riyad Bank as the sole underwriter, along with Saudi Investment Bank and Bank Al-Bilad as mandated lead arrangers.

    “The loan arrangement comprises a mix of conventional and Islamic financing and adheres to RSG’s Green Loan Framework, which was first established when it secured private funding from a consortium of four banks for the Red Sea destination in 2021,” the statement added.

    The announcement followed RSG’s opening of its first properties for sale at Amaala, including branded residential communities and a five-bedroom villa on a private island.

    Kuwait’s oil and gas sector has been in crisis in recent months due to disruption from the regional conflict that started after the US and Israel attacked Iran on 28 February 2026.

    A preliminary peace agreement between the US and Iran, which was announced on 14 June, has increased optimism that disruption to the sector will decrease in the coming weeks.

    Under the terms of the agreement, both sides have stated that the free flow of vessels will be permitted through the Strait of Hormuz, through which nearly all of Kuwait’s crude oil is normally exported.

  • Chinese firm wins $265m Saudi hospital contract

    24 June 2026

    Zhejiang Construction International, the local subsidiary of Chinese contractor Zhejiang Construction Investment Group, has won a $265m contract to build the Prince Mohammed Bin Fahd University Speciality Hospital in Al-Khobar.

    Construction is expected to take three years from the start date.

    Prince Mohammed Bin Fahd University awarded the contract.

    Located in Al-Raja district, Al-Khobar, in Saudi Arabia’s Eastern Province, the hospital project will cover about 60,000 square metres.

    The contract covers the construction of a 10-storey hospital building, two five-storey auxiliary buildings connected by corridors and a basement.

    Work will include civil works, mechanical and electrical installation, curtain walling, landscaping, detailed design and the procurement of medical equipment.

    The award is the latest in a series of contracts secured by Chinese contractors from Saudi entities in recent months.

    Last week, MEED reported that Saudi Arabia’s Ministry of Municipalities & Housing awarded contracts worth more than SR1.9bn ($506m) to Chinese contractors for two residential developments in the kingdom.

    China Architectural Construction Corporation won the first contract, valued at SR875m ($233m), to build 2,010 housing units at the Al-Ruba residential project in Riyadh.

    China State Construction Engineering Corporation secured the other contract, valued at more than SR1bn ($266m), for the Al-Rasha Al-Faisaliah residential project in Dammam, comprising 2,426 housing units.

    GlobalData expects Saudi Arabia’s construction industry to record average annual growth of 5.2% in 2025-28, supported by investments in transport, electricity, housing and tourism infrastructure, as well as the $850bn-plus gigaprojects programme.
