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.

  • KBR re-evaluates design for Libya oil project

    10 July 2026

     

    US-headquartered KBR is responsible for re-evaluating the front-end engineering and design (feed) for the project to develop the J6 North Gialo field in Libya, according to industry sources.

    In June, MEED reported that Libya’s Waha Oil Company (WOC), a subsidiary of the state-owned National Oil Corporation (NOC), had launched a review into the tender process for the J6 North Gialo oil field development project, and that this would include re-evaluating the feed work.

    The Waha concessions are held by a consortium of Libya’s NOC, which holds 59.16%; TotalEnergies, holding 20.42%; and US-based ConocoPhillips, with 20.42%.

    They are operated by WOC, which is 100% owned by NOC.

    KBR has previously provided engineering services for major national projects in Libya, such as the Great Man-Made River project, which is widely recognised as the largest irrigation project in the world.

    In March, KBR was awarded a contract by Zallaf Exploration, Production & Refining of Oil & Gas Company to provide project management and technical services for the South Refinery project in Libya’s southern city of Ubari.

    Under the terms of the contract, KBR will provide contract management, project management and supporting technical services throughout the engineering, procurement and construction (EPC) phases of the project.

    The EPC work is expected to be executed over a 50-month period.

    In its statement, KBR said that the project is aligned with its “long-standing commitment to advancing vital oil and gas infrastructure in Libya”.

    In March, MEED reported that South Korea’s Daewoo had pulled out of the tender process for Libya’s J6 North Gialo oil field development project.

    Daewoo had formed a partnership with Egypt’s Petrojet to participate in the tender process.

    The only other company to submit a bid for the project was UK-based Petrofac, which filed for administration in October last year.

    In January, TotalEnergies signed an agreement extending the Waha concessions agreement up to 31 December 2050.

    This agreement set new fiscal terms, allowing an increase in the production of these concessions that were, at the time, producing about 370,000 barrels of oil equivalent a day (boe/d).

    In January, TotalEnergies said that the deal paved the way for “a new phase of investments, including the development of the North Gialo field, which is expected to add 100,000 boe/d of production”.

    The J6 North Gialo project is the first of three field development projects that WOC has prioritised.

    The other two are known as NC98 and Gialo 3.

    Together, the three projects are expected to double Waha’s production from about 300,000 barrels a day (b/d) of oil to 600,000 b/d.

    The Waha concession covers 13 million acres.

  • Qiddiya to tender high-speed rail in September

    10 July 2026

     

    Saudi Arabia’s Royal Commission for Riyadh City, in collaboration with Qiddiya Investment Company and the National Centre for Privatisation & PPP, are expected to float the tender in September for the Qiddiya high-speed rail project in Riyadh.

    MEED understands that the clarification process is ongoing for the engineering, procurement, construction and financing (EPCF), as well as the public-private partnership (PPP) packages.

    The Qiddiya high-speed rail project, also known as Q-Express, will cover 84 kilometres, connecting King Salman International airport and King Abdullah Financial District with Qiddiya City.

    In April, MEED exclusively reported that the clients had received prequalification statements from firms for the EPCF package of the project.

    MEED also reported in May that firms were forming joint ventures for the PPP package of the project.

    The line will operate at speeds of up to 250 kilometres an hour, reaching Qiddiya in 30 minutes.

    There are five stations planned: Qiddiya Grand Central Station, Qiddiya Uptown Station, King Abdullah Financial District, Terminal 6 King Salman International airport (KSIA) and Iconic Terminal at KSIA.

  • Middle East construction cost inflation to hit 5.1% by 2027

    9 July 2026

    Construction cost inflation in the Middle East is forecast to reach 5.1% in 2027, the second-highest of any region worldwide, as global demand for data centres tightens contractor capacity and deepens shortages of skilled labour.

    The projection comes from the Global Construction Market Intelligence report, published by UK programme manager Turner & Townsend. The report draws on data from 112 markets across 44 countries, gathered between 2 March and 20 March 2026.

    Only Africa is expected to see steeper cost escalation, at 7%. Australia and New Zealand follow the Middle East at 4.9%, while the EU records the lowest figure at 2.8%. Globally, construction cost inflation is set to rise from 4.2% in 2025 to 4.5% in 2026 before flattening in 2027.

    The report identifies a two-speed market. Data centres are now the most in-demand construction sector globally, followed by industrial and logistics. More than 70% of the 112 markets surveyed report tightening or overstretched contractor capacity in the data centre sector. By contrast, more than 79% of markets show balanced or spare capacity across hospitality and leisure, residential and commercial development.

    Skills shortage

    Labour availability has displaced material costs as the primary driver of cost escalation. About 71% of markets report labour shortages. Skills deficits are most acute in mechanical, electrical and plumbing (MEP) trades, with 87% of markets reporting MEP shortages. These trades are central to data centre delivery.

    The findings carry weight for the GCC, where sovereign programmes in Saudi Arabia and the UAE are competing for the same contractor pools that artificial intelligence (AI) infrastructure now draws on. Regional governments have announced large data centre commitments alongside gigaprojects, housing and transport schemes, placing further strain on an already stretched supply chain.

    Turner & Townsend says that construction input costs have stabilised over the past year, with supply chain resilience built since the pandemic limiting the impact of recent volatility. Cost drivers are becoming more localised and sector-specific rather than the product of international shocks.

    Energy market exposure introduces a separate risk. The report cites oil prices, higher transport and freight costs, and volatility in petrochemicals inputs as significant challenges. Disruption to shipping routes lengthens lead times and adds supply chain volatility.

    Conflict assumptions

    The baseline scenario assumes a relatively short-lived conflict in the Middle East and a moderate rise in energy commodity prices in 2026. A prolonged or escalating conflict would produce more pronounced effects on inflation, supply chains and construction costs.

    New York remains the world's most expensive construction market at $7,938 a square metre, followed by San Francisco at $7,883 and Geneva at $6,985. London ranks fifth at $6,032.

    North America carries the highest regional labour costs, with an average hourly wage of $79.5, ahead of the EU at $75.6 and Australia and New Zealand at $68.

    Digital adoption remains uneven, though momentum is building. Sixty-six percent of markets report that AI capability now carries more weight in tendering and client discussions than it did 12 months ago.

  • Contractor appointed for Dubai’s One B Tower

    9 July 2026

     

    Dubai-based construction firm Naresco Contracting has been awarded a contract to build One B Tower, located on Dubai's Sheikh Zayed Road.

    Local real estate developer Wasl Group awarded the contract.

    It covers a 47-storey high-rise tower offering a mix of one- to four-bedroom residential units.

    The project is also known as One Billion Meals Endowment Tower.

    The enabling works were undertaken by local firm APCC Building Contracting.

    Netherlands-headquartered UN Studio is the project architect.

    Dubai-based firm Studio International Engineering Consultants is the project consultant.

    The project is slated for completion by 2028.

    This is the second major contract to have been awarded by Wasl Group this year for a residential development.

    In January, the firm awarded an estimated $250m deal to build the Avenue Park Towers project in Dubai to South Korean contractor Ssangyong Engineering & Construction.

    The development comprises two mixed-use buildings offering residential and commercial facilities. One of the towers will have 43 floors while the other will have 37.

    The project is slated for completion by 2028.

    Wasl Group's latest contract award in the UAE market is backed by heightened real estate activity in the construction sector, with schemes worth over $323bn in the execution or planning stages, according to UK analytics firm GlobalData.

    The company forecasts that output from the UAE’s residential construction sector will grow by 3% in real terms in 2026-29, supported by infrastructure, energy and utilities developments, as well as residential construction projects.

  • Iran and US break peace deal and resume Gulf attacks

    9 July 2026

    Iran and the US have once again traded attacks in the Gulf region, in the worst exchange of fire since the two nations signed an interim peace deal in June.

    US Central Command (CentCom) said on 7 July that it had launched strikes in response to attacks on three oil tankers in the Strait of Hormuz, hitting more than 80 targets including air defence systems, coastal radar and fast boats.

    In retaliatory attacks on 8 July, Iran said it had targeted US military sites in Bahrain and Kuwait.

    Oil prices have spiked following the strikes, with global benchmark Brent crude trading at $77.32 a barrel as of 1pm Gulf Standard Time.

    UK Maritime Trade Operations (UKMTO) said a tanker travelling through the strait had reported a fire after an unknown projectile hit an engine room on 6 July.

    In two separate incidents on 7 July, a tanker reported it had been hit as it exited the strait but was able to proceed to its next port of call, while another tanker reported sustaining minor structural damage after being struck, UKMTO said.

    Qatar and Saudi Arabia have denounced the attacks, each saying a tanker from its country had been hit while transiting in or near the strait, and blaming Iran.

    A spokesperson for Qatar's foreign ministry, Majed Al-Ansari, said it held Iran fully responsible for an apparently targeted attack on a vessel called Al-Rekayyat as it transited near the Strait of Hormuz.

    Saudi Arabia's foreign ministry said Iran had targeted the Saudi tanker Wedyan as it crossed the strait. The owner of the very large crude carrier, the kingdom’s national shipping company Bahri, confirmed the attack on the vessel in a statement on 7 July, adding that “all crew members are safe and accounted for, and the cargo remains secure”.

    “The vessel remains in a seaworthy condition. The company promptly informed all relevant authorities and continues to work closely with them and other maritime stakeholders, while maintaining continuous communication with the vessel's crew and closely monitoring the situation,” Bahri said.

    “Bahri continues to closely monitor developments in the region and has implemented appropriate precautionary measures to support the safety of its people, vessels and operations,” it added.

    Breakdown of peace deal

    Separately, the US also said it had revoked its temporary suspension of sanctions on Iranian oil sales. Iran's speaker Mohammad Bagher Ghalibaf accused the US of breaching their memorandum of understanding (MoU) on this issue, and others, including the attacks in southern Iran and "violating Iranian adjustments in the strait".

    Missiles and drones were launched at "85 key US military facilities", including a US Navy headquarters and an air base in Kuwait, the Islamic Revolutionary Guard Corps (IRGC) said.

    Iranian state media agency Irna also reported the death of an IRGC guard in the US strikes, “after being struck by shrapnel from a projectile".

    Kuwait has responded to the Iranian strikes on its country, lambasting the "repeated attacks".

    Talks on reaching a permanent peace deal have been on hold due to the state funeral in Iran for the late Supreme Leader Ayatollah Ali Khamenei, who was killed on 28 February – the first day of US-Israeli strikes on Iran.

    Early on 7 July, Iran's deputy foreign minister described the US attacks as a violation of the US-Iran MoU signed on 14 June, and warned Tehran would "take decisive measures".

    The US had said there would be consequences for what it called the "wholly unacceptable" attacks on the three tankers.

    CentCom said that in addition to 60 small boats, it had struck Iranian missile launch sites and command centres. It did not give the locations of its targets.

    It said the strikes were "to impose heavy costs for targeting and attacking commercial shipping crewed by innocent individuals in an international waterway".

    Before the strikes, the US Treasury revoked a waiver that had temporarily lifted oil sanctions on Iran and was part of the MoU signed by Washington and Tehran in June.

    Iran's foreign ministry called the move a breach of the MoU and said it proved the "bad faith, inconsistency and unreliability" of the US government.

    It added that Tehran "will take whatever measures it considers necessary to safeguard its national interests and national security".
