Dubai prequalifies EPC firms for $22bn tunnels project

2 August 2024

Dubai Municipality has prequalified engineering, procurement and construction (EPC) companies that can bid, along with investor and operation and maintenance (O&M) partners, for the contracts to develop four of the six packages of the $22bn Dubai Strategic Sewerage Tunnels (DSST) project.

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

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

The second package, J2, covers the southern section of the Jebel Ali tunnels, which will extend 16km and have a link stretching 46km.

W for Warsan, the third package, comprises 16km of tunnels, TPS and 46km of links.

J3, the fourth package, comprises 129km of links.

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

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

The prequalified EPC companies for packages J1, J2 and W 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)

  • SK Ecoplant (South Korea) 
  • Strabag Dubai (Austria)
  • The Petroleum Projects & Technical Consultation Company (Petrojet) – Egypt
  • Webuild  (Italy)

EPC companies that have been prequalified for package J3 are:

  • Acciona Construccion (Spain) – Dubai branch
  • Alghanim International General Trading & Contracting (Kuwait) 
  • China Railway Group (China)
  • China State Construction Engineering Corporation (China)
  • Daewoo Engineering & Construction (South Korea)
  • DETech Contracting
  • Archirodon Construction (Overseas) Company (Greece) / BESSAC (France)
  • China Civil Engineering Construction Corporation (China) – Dubai branch / Shanghai Tunnel Engineering Company (STEC) / China Railway 14th Bureau Group Corporation 
  • Gulermak Agir Sanayi Insaat (Turkiye) / DETech Contracting (local) 
  • International Foundation Group (IFG, local) / General Construction Company (local)
  • Nael Construction & Contracting (UAE) / Concord for Engineering & Contracting (Egypt) – Dubai branch
  • National Marine Dredging Company (local) / Afcons Infrastructure (India) / ITD Cementation India

  • Mohammed Abdulmohsin Al-Kharafi & Sons (Kuwait)
  • Porr (Austria)
  • Power Construction Corporation of China – Dubai branch
  • Strabag (Austria)
  • Tecton Engineering & Construction (local)
  • The Petroleum Projects & Technical Consultation Company – Petrojet (Egypt)

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

Dubai Municipality said the prequalified companies have received the pre-request for proposal phase versions of the technical schedules.

For each EPC contractor, the technical prequalification may be in respect of one or more components – which include deep sewer tunnels, terminal pumping stations and/or link sewers, as applicable – of one or more DSST-TLT packages.

MEED understands the project’s remaining two packages, the expansion and upgrade of the Jebel Ali and Warsan STPs, will be procured in a process separate from the four DSST-DLT components.

According to a source close to the project, packages J1 and W will be tendered together as separate contracts first, followed by J2 and J3, with the requests for proposals (RFPs) to be issued sequentially, staggered around six to 12 months apart

Unconventional procurement process

In addition to its size, the project is gaining significant interest due to its unique procurement approach, whereby EPC contractors’ prequalification precedes developers’ prequalification.

"The idea is to issue the technical information pack to the prequalified EPC contractors before the prequalification process for investors starts, allowing EPC contractors time to undertake the design process," the source said.

"These designs should be ready once the Dubai Municipality completes the prequalification process for investors, saving roughly three months compared to the usual route where the prequalification process for developers and EPC contractors are done simultaneously."

The staggered prequalification process is expected to help ensure the RFP process takes around six months rather than the typical nine-month period.

"It will also encourage a stronger partnership approach to implementing the project's various packages," said the source.    

Dubai Municipality recently invited investors and developer firms to submit their statements of qualifications by 5 September for the contracts to develop and operate various packages of the project.

The client is expected to issue the RFP to prequalified investors by the end of September.

The bidders for each of the PPP RFPs will be prequalified consortiums comprised of sponsors, EPC contractors and O&M contractors.

MEED previously reported that the overall project will require a capital expenditure of roughly AED30bn ($8bn), while the whole life cost over the full concession terms of the entire project is estimated to reach AED80bn.

Sustainable project

The project aims to convert Dubai’s existing sewerage system from a pumped system to a gravity system by decommissioning the existing pump stations and providing “a sustainable, innovative, reliable service for future generations”.

Dubai currently has two major sewerage catchments. The first in Deira is Warsan, where the Warsan sewage treatment plant (STP) treats the flow.

The second catchment, called Jebel Ali, is in Bur Dubai, where the wastewater is treated at the Jebel Ali STP.

According to a source close to the project, the DSST will replace 120 pump stations, saving approximately 100 gigawatt-hours of electricity annually.

  • Alba to acquire EU’s largest primary aluminium producer

    6 March 2026

    Aluminium Bahrain (Alba) has reached an exclusive agreement with American Industrial Partners (AIP) to acquire 100% of France-based Aluminium Dunkerque.

    The proposed cash transaction, which will be fully underwritten by a syndicate of banks, aims to create a geographically diversified industrial group with a combined footprint across the GCC and Europe. Located in Loon-Plage, the Dunkerque facility produces approximately 300,000 tonnes of aluminium a year and is considered one of the lowest-carbon primary producers in Europe.

    The move aligns with Alba’s broader strategy to build a low-carbon aluminium platform. Alba’s chairman, Khalid Al-Rumaihi, said in a statement that the partnership will help the group capture market opportunities driven by global decarbonisation and electrification.

    As part of the deal, Alba has expressed a willingness to offer a shareholding position to the French sovereign wealth fund, Bpifrance, to foster a strategic partnership. The transaction is expected to close in 2026, pending consultative processes with works councils and regulatory approvals from French and EU authorities.

    AIP was represented in this transaction by Goldman Sachs, Societe Generale and Messier & Associes as financial advisers, and Jones Day and Baker Botts as lawyers.

    Alba was represented in this transaction by Rothschild & Co as financial adviser, and White & Case and BDGS Associes as lawyers.

  • Conflict duration will determine impact on aviation sector

    6 March 2026

    The Middle East’s aviation and travel sectors are grappling with the fallout following the 28 February military actions involving the US, Israel and Iran, and subsequent retaliatory strikes.

    According to a 5 March report by Fitch Ratings, the duration of this disruption will be the key factor in determining the financial and operational impact on airlines, airports and the broader hospitality industry. While the current baseline suggests the conflict may last less than a month – limiting the damage to rated issuers – the scale of the immediate disruption is unprecedented for the region’s aviation hubs.

    Between 28 February and 5 March, more than 15,000 flights were cancelled across seven major regional airports, affecting over 1.5 million passengers. Major international hubs, including Dubai, Abu Dhabi and Doha, have faced significant congestion and scheduling challenges as carriers scramble to reroute or divert services.

    The impact is most acute for carriers whose primary hubs are located within the affected corridor. “Flight operations over the UAE and Qatar appear particularly constrained, which is important given the scale of the region’s hub carriers’ operations,” said Fitch.

    Airlines are facing a sharp spike in operating costs. Rerouting around restricted airspace often requires longer flight paths, additional technical stops, and increased expenses for crew overtime and passenger handling. While passenger compensation may be limited because the conflict is classified as an event outside the airlines’ control, the cost of issuing refunds, vouchers and accommodation remains a burden on balance sheets.

    Another challenge is higher fuel prices, which is a perennial risk for the industry during Middle East instability. Fitch said most of the region’s carriers have maintained a disciplined approach to risk management with hedge levels for the next three months ranging from 50% to over 80%, providing a significant buffer against immediate price volatility.

    The insurance market is also seeing shifts. Aviation policies typically grant insurers the right to cancel cover during active conflict. “War cover would typically relate to aircraft damage, although business interruption policies usually exclude war risks,” said Fitch.

    The broader outlook for regional travel remains resilient. Global lodging companies with exposure to the Middle East are generally well-diversified enough to absorb the impact of travel disruptions. Similarly, aircraft lessors – supported by globally diversified fleets and long-term, fixed-rate lease contracts – face very limited credit risk.

    For the region’s major aviation players, the focus now is on how quickly the safe haven status of the Gulf’s primary hubs can be restored. If the conflict remains short-lived, the impact on annual growth and profitability is expected to be temporary.

    A prolonged period of airspace instability would test the flexibility of the region’s transport infrastructure at a time when aviation remains a central pillar of the GCC’s economic diversification strategy.

  • GCC banks show resilience amid regional conflict

    5 March 2026

    Register for MEED’s 14-day trial access 

    The GCC’s banking sector is facing its most significant test in years following the attacks by Israel and the US on Iran, and the subsequent strikes launched by Iran on all six GCC states.

    The data so far indicates that the region’s finances are holding firm. “Fitch believes GCC sovereign ratings generally have sufficient headroom to withstand a short regional conflict that does not escalate significantly further, including in most cases substantial assets that provide a buffer against short-term hydrocarbon revenue disruption,” it said in a report on 3 March.

    In the UAE, the Central Bank of the UAE (CBUAE) issued a statement on 5 March saying that the nation’s banking and financial sector continues to operate normally. It said the UAE’s banking assets now exceed AED5.42tn ($1.48tn), supported by a capital adequacy ratio of 17% and a liquidity coverage ratio of 146.6%, adding that both figures sit comfortably above international regulatory requirements.

    “The UAE’s banking and financial sector continues to maintain very strong levels of capital adequacy and liquidity … reflecting the scale, resilience and strength of financial institutions operating in the country,” said Khaled Mohamed Balama, governor of the CBUAE.

    While the immediate financial metrics are sound, the broader operating environment is not without its challenges. Fitch notes that the attacks raise risks to the 2026 baseline, which had previously assumed robust non-oil growth driven by the region’s massive pipeline of diversification projects.

    Economic impact

    The conflict has already impacted the real economy. Air travel suspensions, a slowdown in consumer activity and shifting risk perceptions regarding tourism could weigh on non-oil GDP if the tension lingers. Fitch highlighted that the key metric to monitor will be the “strength of operating conditions, particularly non-oil growth and general confidence in the region”.

    The critical variable remains the duration of the conflict. If hostilities are contained within a month – as is the current expectation among analysts – the impact on GCC economic growth is likely to be temporary.

    There are specific regional nuances to watch. While most GCC banks enjoy ample liquidity, those in Qatar and Saudi Arabia have historically faced tighter conditions. “The conflict could make it more challenging for GCC-based entities to issue debt in overseas capital markets. This could particularly increase Saudi banks’ reliance on more expensive domestic markets,” said Fitch. 

    For now, the strategy from both regulators and ratings agencies is one of cautious optimism. The region’s capital expenditure programmes and diversification drives provide a structural momentum that is difficult to derail in the short term.

    Fitch concluded that as long as energy infrastructure remains intact and public spending continues to shore up growth, the GCC’s financial institutions are well-positioned to navigate the crisis.

  • Fitch Ratings sees limited oil price impact of Iran conflict

    5 March 2026

    Register for MEED’s 14-day trial access 

    The de facto blockade of the Strait of Hormuz in the Gulf by Iran since 28 February is likely to be temporary given its vital economic role in global oil trade, according to credit ratings agency Fitch Ratings.

    This, alongside global oil market oversupply, should limit oil price rises and mitigate any potential disruptions to Iranian oil supply, Fitch Ratings said in a note.

    As a result, the ratings agency does not expect significant upside to its December 2025 assumption of an average Brent oil price of $63 a barrel for 2026.

    “The strait is not formally closed, but vessels are increasingly avoiding it given the risk of attack by Iran or its proxies. Oil majors have halted shipments for safety reasons, and insurers are cancelling war risk cover for vessels. However, we expect this effective closure of the strait to be temporary. It is a vital artery for seaborne oil transportation, with limited alternative routes,” said Angelina Valavina, EMEA head of Natural Resources and Commodities at Fitch Ratings.

    Oil prices rose on 5 March, extending a rally as the ‌escalating US-Israeli war with Iran continued to disrupt supplies, prompting some major producers to cut production and others to take measures to ensure supply security.

    Brent crude was up $2.35, or 2.9%, at $83.75 a barrel at 12pm Gulf Standard Time, a fifth session of gains. US ​West Texas Intermediate crude rose $2.42, or 3.2%, to $77.08.

    ALSO READ: Oil prices rise to highest in a year as regional conflict deepens

    “Prior to the conflict, around 20 million barrels a day (b/d) of crude oil and petroleum products transited the strait, accounting for about a quarter of global seaborne oil trade and a fifth of global oil consumption. About half of the oil volumes transported through the strait are exports from Saudi Arabia and the UAE, with the remainder from Iraq, Kuwait and Iran. About half of these exports go to China and India.

    “A protracted closure would affect both exporting and importing countries and therefore is not our baseline assumption. If the strait were to remain effectively closed for a protracted period, naval protection for tanker navigation could be considered, as occurred during the 1980s' Iran-Iraq war,” Valavina said in the note from Fitch Ratings.

    “In addition, the global oil market is oversupplied, which should limit the geopolitical risk premium and cap risks to oil price increases. Global supply growth exceeded demand growth in 2025. Fitch expects this trend to continue in 2026. Supply increased by about 3 million b/d in 2025, while demand grew by well below 1 million b/d,” Valavina said.

    “We forecast supply growth of 2.4 million b/d in 2026, with demand growth of about 0.8 million b/d. Half of 2025-26 supply increases come from unaffected non-Opec+ producers. Opec+ spare production capacity is 4.3 million b/d,” she added.

    “In addition, global observed oil inventories rose by 1.3 million b/d in 2025 to reach their highest level since March 2021. Total global inventories stood at 8.2 billion barrels at end-2025. This is sufficient to cover a halt in oil shipments via the Strait of Hormuz for over 400 days.

    “Saudi Arabia and the UAE have some infrastructure to bypass the strait, which may mitigate transit disruptions. Saudi Aramco (Saudi Arabian Oil Company; A+/Stable) operates the 5 million b/d East–West crude oil pipeline to an export port on the Red Sea. The UAE operates a 1.5 million b/d capacity pipeline linking its oil fields to the Fujairah export terminal on the Gulf of Oman with a maximum achieved flow of 1.8 million b/d.

    “While Iran is a sizeable oil producer, producing about 3.5 million b/d and exporting about 2 million b/d, it accounts only for about 3.5% of global crude oil production. This means that potential supply disruption would be offset by global market oversupply.”

    Valavina concluded: “However, the duration and intensity of the increasingly regional conflict remain uncertain. Any protracted blockage of the strait or material and sustained damage to the region’s oil and gas production and transportation infrastructure would materially affect oil markets and likely result in a more material rise in our base case 2026 oil price assumption. Oil price volatility would rise if there were to be any material disruption to Iranian oil production.”
