Expectation mounts as Dubai tunnels tender nears

20 February 2025

 

Prequalified firms have been speculating about the project structure that will be offered to developers; engineering, procurement and construction (EPC) contractors; and operations and maintenance companies for the first two packages of the $22bn Dubai Strategic Sewerage Tunnels (DSST) project.

"We are keen to find out if the client will be issuing a lease or licence," one source told MEED, adding that there has also been speculation about whether a sovereign guarantee will be issued, and by whom.

The tender for the first two packages of the DSST project is expected to be issued before the end of this month. 

Given the scale of each package and the capital expenditure required, it is also unclear whether the project client, Dubai Municipality, will require 50% committed financing for bid purposes, noted another source.   

At least four companies have been prequalified as lead members of potential consortiums that can bid for the contracts.

MEED previously reported that the firms that have been prequalified as lead members for the project's four main tunnels and links packages include Ajman-based Etihad Water & Electricity, a team comprising Japan's Itochu and Australian investment firm Plenary, and Saudi Arabia's Vision Invest.

Belgium's Besix is also understood to be among those prequalified to bid as a developer lead member.

According to industry sources, the Plenary-Itochu consortium will likely include South Korea's Samsung C&T and Italy's Webuild.

MEED understands that final partnering negotiations are still under way for the other teams.

The EPC team of Abu Dhabi's National Marine Dredging Company and India's Afcons Infrastructure, and separately PowerChina, are understood to be engaged in final talks with either the Vision Invest or Etihad Water & Electricity consortiums, although it has also been suggested that Vision Invest and Etihad Water & Electricity could bid as one team.

"There is a possibility of team consolidation due to lack of bankable EPC," one of the sources said.

The same source said that Japan's Marubeni and Saudi Arabia's AlJomaih Water & Energy might also still be considering bidding for the contracts.

MEED reported in October that more than a dozen companies were keen to prequalify as investors or sponsors for the planned public-private partnership (PPP) project.

They included:

  • Abrdn Investcorp Infrastructure Investments Manager (UK)
  • Besix (Belgium)
  • China Railway Construction Corporation (CRCC)
  • China Railway Engineering Group (CREG)
  • China State Construction Engineering Corporation (China)
  • Itochu (Japan)
  • Nesma Company (Saudi Arabia)
  • Plenary (Australia)
  • Samsung C&T (South Korea)
  • Vision Invest (Saudi Arabia)
  • Webuild (Italy)
Six packages

It is understood that packages J1 and W will be tendered together as separate contracts first, followed by J2 and J3, with the requests for proposals to be issued sequentially, staggered about six to 12 months apart.

The first package, J1, comprises Jebel Ali tunnels (North) and terminal pump stations (TPS). The tunnels will extend approximately 42 kilometres (km), and the links will extend 10km. 

The other package, W for Warsan, comprises 16km of tunnels, TPS and 46km of links.

The overall project will require a capital expenditure of about AED30bn ($8bn), while the whole-life cost over the full concession terms of the entire project is estimated to reach AED80bn.

The investor prequalification process for the scheme comes after the client prequalified EPC contractors that can partner with the developers or investors to bid for the contracts.

The prequalified EPC contractors for the J1 and W packages, along with the J2 package, are: 

  • Acciona Construccion (Spain) – Dubai branch
  • Besix Construct (Belgium)
  • China Harbour Engineering (China)
  • China Railway Group (China)
  • China State Construction Engineering Corporation (China)
  • Daewoo Engineering & Construction (South Korea) 
  • Dogus Insaat VE Ticaret Anonim Sirketi (Turkiye) – Abu Dhabi
  • FCC Construcccion (Spain)
  • Archirodon Construction (Overseas) Company (Greece) / BESSAC (France)
  • China Civil Engineering Construction Corporation – Dubai Branch / Shanghai Tunnel Engineering Company (STEC) / China Railway 14th Bureau Group Corporation 
  • Gulermak Agir Sanayi Insaat (Turkiye) / DETech Contracting (local)
  • National Marine Dredging Company (local) / Afcons Infrastructure (India) / ITD Cementation India 
  • The Arab Contractors (Osman Ahmed Osman & Company, Egypt) / Darwish Engineering Emirates (local) / AqualiaMACE Contracting Operation & General Maintenance (local)
  • Larsen & Toubro (India)
  • Porr (Austria)
  • Power Construction Corporation of China (China) – Dubai branch
  • Samsung C&T Corporation (South Korea) – Dubai Branch
  • SK Ecoplant (South Korea) 
  • Strabag Dubai (Austria)
  • The Petroleum Projects & Technical Consultation Company (Petrojet) – Egypt
  • Webuild  (Italy)
DSST packages

Under the current plan, the $22bn DSST project is broken down into six packages, which will be tendered as PPP packages with concession periods lasting between 25 and 35 years.

In addition to J1 and W, J2 covers the southern section of the Jebel Ali tunnels and will extend 16km and have a link stretching 46km.

J1, J2, W and J3 will comprise the deep sewerage tunnels, links and TPS (TLT) components of the overall project.

J1, J2 and W will be procured under a design, build, finance, operate and maintain model with a concession period of 25-35 years.

J3 will be procured under a design, build and finance model with a concession period of 25-35 years. Once completed, Dubai Municipality will operate J3, unlike the first three packages, which are planned to be operated and maintained by the winning PPP contractors.  

The project’s remaining two packages entail expanding and upgrading the Jebel Ali and Warsan sewage treatment plants. MEED understands that these packages will be procured at a later stage.

  • 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.

    17 September 2026

    Abu Dhabi-based sovereign wealth fund Mubadala Investment Company and local developer Aldar have completed the acquisition of Masdar City Square at Masdar City, in a transaction valued at AED918m ($250m).

    The deal was executed through their joint venture established in 2024.

    Masdar City Square comprises more than 47,000 square metres (sq m) of net leasable area across seven office buildings.

    Completed in Q1 2026, the development is 99% occupied. Tenants include Taqa, the Department of Energy, Emirates College and the Mohamed Bin Zayed University of Artificial Intelligence.

    The transaction expands the joint venture’s real estate portfolio in Masdar City, which is now valued at AED4.7bn ($1.3bn).

    Masdar City is one of the region’s leading hubs for clean energy, artificial intelligence, advanced research and sustainable urban development.

    The joint venture acquired The Link project at Masdar City for AED654m ($178m) in April.

    Comprising about 32,000 sq m of net leasable area across five buildings, The Link is fully leased to a portfolio of major tenants, including Abu Dhabi Future Energy Company (Masdar) and the Mohamed Bin Zayed University of Artificial Intelligence.

    The asset includes Grade A, Leed Platinum office space, a net-zero-energy headquarters building, a multi-use hall and residential accommodation, supporting its position as a high-performing, integrated component of Masdar City.

  • 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.
