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.

Aramco and Emerson partner for corrosion management3 June 2026
Saudi Aramco has entered into a partnership with US-based industrial automation provider Emerson to jointly develop corrosion management systems.
As part of the corrosion research and development collaboration, Aramco will “combine its expertise and intellectual property with Emerson’s advanced corrosion solutions to digitalise and transform corrosion management”, Emerson said in a statement.
For Aramco, corrosion management is a strategic priority that is closely linked to operational performance, safety and environmental stewardship. Continuous corrosion monitoring can replace labour-intensive and potentially hazardous manual inspections while providing a reliable stream of digital data to support decision-making and asset integrity management.
The collaboration builds on the companies’ existing relationship. In May, Emerson announced the deployment of an artificial intelligence-driven optimisation system for Aramco.
The current phase of that initiative focuses on expanding a hybrid modelling approach for hydrocracker units across Aramco’s operations. The expansion is expected to improve model accuracy while demonstrating the scalability and robustness of the AI-driven optimisation strategy across the company’s asset base.
Emerson has steadily expanded its presence in Saudi Arabia over the past 16 years. Key milestones include the opening of facilities in Jubail, Dammam and Dhahran, as well as the launch of a manufacturing hub at King Salman Energy Park (Spark) in 2024.

Iranian drones hit Kuwait International airport’s Terminal 13 June 2026
Kuwait International airport was struck by a fresh wave of hostile drone attacks on 3 June. The drones caused significant structural damage to Terminal 1 and wounded several individuals.
Brigadier General Saud Abdulaziz Al-Otaibi, official spokesman for the Ministry of Defence, blamed the strikes on “criminal Iranian aggression”. He confirmed that the injured had been evacuated for medical care and stated that the armed forces remain in a state of complete readiness to secure the state.
The incident is the third major drone strike on the hub in recent months. On 1 April, a drone strike hit fuel tanks managed by Kuwait Aviation Fuelling Company, sparking massive fires. On March 28, another multi-drone raid severely damaged the airport’s primary radar systems.
The airport is being expanded with the construction of a new terminal, and works on the project are expected to be completed by 2027. It consists of three packages.
These are:
- Package 1: Main works – $4,329m
- Package 2: Multistorey car park building, connection roads, bridges and landscaping works – $550m
- Package 3: Aircraft parking, runways and service buildings – $950m
Turkiye’s Limak Holding is executing the main works.
The terminal building was designed by Foster+Partners and Gulf Consult.

Consortium signs PPA for Taweelah C power plant3 June 2026
Emirates Water & Electricity Company (Ewec) has confirmed it has signed a power-purchase agreement (PPA) with a developer consortium for the Taweelah C independent power producer (IPP) project.
The agreement, which will run through to 2050, was signed with Abu Dhabi National Energy Company (Taqa), Al-Jomaih Energy & Water Company (Saudi Arabia) and Sembcorp Industries (Singapore), the utility said in a statement.
Taqa will own a 60% stake in the project, with the international consortium holding 40%. The ADX-listed company will also own 40% of the project’s operations and maintenance company, while the international consortium will own 60%.
Last month, MEED exclusively revealed that the winning consortium had been selected for the project, with the PPA initially expected to be signed in mid-May.
It is understood that China Energy Engineering Corporation (CEEC) will be the engineering, procurement and construction contractor.
The combined-cycle gas turbine plant will have a capacity of about 2.5GW. It will be located at the Al-Taweelah power and desalination complex, about 50 kilometres northeast of Abu Dhabi city.
Taweelah C is part of Ewec’s wider programme to support the UAE’s Net Zero by 2050 Strategic Initiative and the Abu Dhabi Department of Energy’s Clean Energy Strategic Target 2035.
Ewec plans to raise solar power capacity to 18GW and wind capacity to 2.6GW by 2035, while reducing the carbon intensity of its power generation by more than half compared with 2019.
The Taweelah C IPP is now expected to start commercial operations in 2029. The facility had previously been scheduled to begin commercial operations in the fourth quarter of 2028.

Local contractor wins Oman water transmission contract3 June 2026

Local contractor Al-Jesr United has won the main engineering, procurement and construction contract to reinforce Oman’s Sur water transmission system.
The contract, awarded by state-owned utility Nama Water Services (NWS), forms part of a project to improve the reliability of potable water supply to Sur, a coastal city about 200 kilometres southeast of Muscat.
The scheme, estimated to cost $80m, is designed to strengthen the network’s resilience during peak-demand periods and emergencies.
The scope of work includes upgrading the pumps at the Sur DP Pump Station with variable frequency drive units and replacing ductile iron pipes and fittings within the facility. It also covers about 17km of new transmission pipelines.
According to regional projects tracker MEED Projects, at least five local firms submitted commercial bids for the contract, which was tendered in August 2025.
These include:
- Al-Jesr United
- Al-Rafaa Trading & Contracting
- Gulf Petrochemical Services & Trading
- Professionals Trading
- Sarooj Construction Company
In June 2024, NWS awarded a $1.3m contract for the project’s design and construction supervision to Muscat-headquartered Ibn Khaldun Almadaen Engineering Consultants.
Sur is home to one of the sultanate’s key desalination plants, which supplies potable water to communities across eastern Oman.
The water transmission project will support network expansion in areas such as Al-Aigah and Ahiae, as the existing ductile iron pipeline serving Wilayat Sur is no longer sufficient to meet current and future demand.
Construction is expected to start in the third quarter of 2026 and take about two years to complete.

Syria to tender gas plant contract3 June 2026

Syria is preparing to tender a project to rehabilitate the Conoco gas plant in Deir ez-Zor province in the east of the country within the next 10 weeks, according to a document published by the US-Syria Business Council.
The gas plant was reclaimed by Syria’s military during an offensive in January this year.
It is Syria’s largest gas plant, but is severely damaged and cannot be operated in its current condition.
Before the country’s civil war, it processed 13 million cubic metres of gas a day.
The US-based companies ConocoPhillips and Novaterra signed a memorandum of understanding with the state-owned Syria Petroleum Company (SPC) to restore the facility in November last year.
Syria is currently in the midst of a push to ramp up oil and gas production and establish itself as a regional energy hub.
Earlier this year, Yousef Qiblawy, chief executive of SPC, said that his organisation was aiming to double national oil production before 2027 and boost output to 800,000 barrels a day by the end of 2029, not including offshore production.
