Dubai Municipality is expected to tender the first two packages of the $22bn Dubai Strategic Sewerage Tunnels (DSST) project imminently.
MEED previously reported 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 client could issue the request for proposals before the end of this week, a source close to the project tells MEED.
MEED reported last week that at least three companies have been prequalified as lead members of potential consortiums that can bid for the contracts.
These include:
- Etihad Water & Electricity subsidiary (local)
- Itochu (Japan) / Plenary (Australia)
- Vision Invest (Saudi Arabia)
According to industry sources, the Plenary-Itochu consortium will likely include South Korea's Samsung C&T and Italy's Webuild.
Final partnering negotiations are still under way for the two other teams, according to sources.
The engineering, procurement and construction (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 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," notes one source.
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 over 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)
MEED previously reported that the bidders for the PPP packages will be prequalified consortiums comprised of sponsors or investors, EPC contractors, and operations and maintenance contractors.
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.

Bahrain’s willingness to disrupt takes flight with Air Asia14 November 2025
Commentary
Colin Foreman
EditorAs the smallest economy in the GCC, Bahrain has long understood that its competitive edge lies in being agile and prepared to disrupt established economic models.
This proactive approach began decades ago with the deregulation of its telecoms sector, positioning it ahead of many GCC peers in opening that market. More recently, the same strategic foresight emerged in the fintech space with the early adoption of regulatory sandboxes and a supportive digital finance ecosystem.
Bahrain’s disruptive lens is now focused on the aviation sector. At the Gateway Gulf investor forum in Manama on 3 November, Bahrain signed a letter of intent with Malaysia-headquartered Capital A Berhad and Air Asia. The agreement covers the establishment of a hub in Bahrain as low-cost carrier Air Asia and its related businesses expand beyond Asia into new markets, including Europe and Africa.
A hub in Bahrain, which is located to the west of its existing hubs in Asia, will allow Air Asia to connect to the European and African markets, allowing it to develop a network that will be a low-cost alternative to the full-service airlines based in the Gulf that also bridge east and west, including Bahrain’s flag carrier Gulf Air.
Bahrain and Air Asia will not be competing on scale; instead, they will disrupt with lower prices. This agility will allow the kingdom to carve out a distinctive niche in an otherwise highly competitive market.
The strategic pivot is made viable by recent, essential capital investment in aviation infrastructure. A new terminal building was opened at Bahrain International airport in 2022. This has significantly increased passenger capacity and modernised operations, creating an attractive platform for a major international low-cost carrier like Air Asia to base its extensive operations.

The project was previously planned to be developed under a conventional model, but will now progress under a public-private partnership (PPP) model.
The line is expected to be developed in two phases. The first phase will connect Qiddiya with KAFD and King Khalid International airport.
The second phase will start from a development known as the North Pole – which is understood to include the Public Investment Fund’s proposed 2-kilometre-tall tower – and travel to the New Murabba development, King Salman Park, central Riyadh and Industrial City in the south of Riyadh.
In November 2023, MEED reported that French consultant Egis had been appointed as the technical adviser for the project.
UK-based consultancy Ernst & Young is acting as the transaction adviser on the project. Latham & Watkins is the legal adviser.
Qiddiya is one of Saudi Arabia’s five official gigaprojects and covers a total area of 376 square kilometres (sq km), with 223 sq km of developed land.

Meraas awards $120m Citywalk expansion project deal14 November 2025
Register for MEED’s 14-day trial access
Local real estate developer Meraas has awarded a AED440m ($120m) contract for the construction of the Northline residential project in the Al-Wasl area of Dubai.
The contract was awarded to the local GCC Contracting Company.
The project includes the construction of three residential buildings. Construction works are expected to begin shortly and the project is slated for completion by 2027.
The enabling works were undertaken by the local International Foundations Group.
The project is part of the recently announced City Walk expansion project.
In June, Merass announced the City Walk Crestlane project as it continued its expansion of the City Walk residential community.
City Walk Crestlane comprises two residential towers offering 198 one- to five-bedroom units.
The project is expected to be completed and handed over by the third quarter of 2028.
Meraas’ latest project contract award in Dubai is backed by heightened real estate activity in the UAE’s construction market. Schemes worth over $323bn are in the execution or planning stages, according to UK analytics firm GlobalData.
The company forecasts that the output of the UAE’s construction sector will grow by 4.2% in real terms in 2025, supported by developments in infrastructure, energy and utilities, as well as residential construction projects.

Contractors prepare bids for Aramco gas compression project13 November 2025

Register for MEED’s 14-day trial access
Saudi Aramco is making progress with the main contract tendering process for a project to boost gas compression capacity at the Shedgum and Uthmaniya processing plants in the kingdom’s Eastern Province.
The Shedgum and Uthmaniya plants currently receive approximately 870 million cubic feet a day (cf/d) and 1.2 billion cf/d of Khuff raw gas, respectively.
Through this multibillion-dollar project, Aramco aims to increase the compression and processing capacity of the two plants, as well as to construct new pipelines to enhance gas transport.
Contractors are preparing bids for several engineering, procurement and construction (EPC) packages of the Shedgum and Uthmaniya gas compression capacity expansion project. Aramco has set a bid submission deadline of 17 November, according to sources.
The Saudi energy giant is understood to have started the solicitation of interest process for the main EPC contract tendering exercise in the fourth quarter of last year.
Aramco then issued the tenders for the EPC packages of the scheme during the second quarter of this year and set an initial bid submission deadline of 17 August, the sources said.
In line with its aim of increasing gas production and processing capacity by 60% by 2030, with 2021 as its baseline, Aramco is investing significant capital in gas projects in the kingdom this year.
Aramco’s capital expenditure (capex) in the third quarter of 2025 stood at $12.55bn, a marginal year-on-year increase of 2%. For the first nine months of the year, the firm registered capex of $37.41bn, an increase of 3.38% compared to the same period last year.
The company previously announced capital investment guidance in the range of $52bn-$58bn for 2025, excluding around $4bn of project financing.

Aramco Stadium races towards completion12 November 2025

Register for MEED’s 14-day trial access
The Aramco Stadium in Khobar is moving forward at an impressive pace as the fast-track project races towards completion in 2026.
The 47,000-seat stadium will be the new home for the Aramco-owned Al-Qadsiah Club and a key venue for the 2027 AFC Asian Cup and the 2034 Fifa World Cup.
The project’s progress stems from detailed planning and an accelerated delivery strategy. The project was conceived in May 2023, with the design process, managed by Aramco, commencing shortly thereafter.
“We completed the design within six months,” said Mohammed Subhi, the Aramco Stadium’s project manager.

The project advanced quickly due to thorough planning and a fast-track delivery approach. Initiated in May 2023, the design phase—overseen by Aramco—was completed within six months
An early engagement approach with the main contractor – a joint venture of Besix and Al-Bawani – was instrumental in maintaining momentum. This partnership began early in 2024, allowing for collaborative input on critical construction elements.
This upfront collaboration minimised pre-construction time, ensuring a rapid transition to site work.
Engineering challenges
The stadium’s architectural design, inspired by the natural whirlpools of the Gulf and featuring interwoven transparent sails, presents significant engineering challenges, particularly in the structural steel and façade work. For spectator comfort, the stadium is equipped with full cooling systems and designed to the highest international standards.Logistics management is another crucial facet of the project, which is located in central Khobar. With thousands of workers on site, the movement of materials is tightly controlled to minimise community disruption.
“We control how many trucks can enter the site and at what time. For example, we cannot cast concrete during the day. It has to be after 6pm, up until the early morning,” said Subhi.
A key priority on site is health and safety, an area where the organisation’s legacy from its oil and gas operations is clearly visible. Subhi explains that the principle of health and safety is part of the company’s DNA and is embodied in the deployment of advanced technology and rigorous standards, which have collectively resulted in over 10 million safe working hours to date.
The project employs a sophisticated Smart Safety Command Centre (SCC), which utilises artificial intelligence-based monitoring and 24/7 surveillance. One key feature of the centre is the crane collision prevention system – a key technological advancement in heavy machinery coordination and a first for the region.
“We have tower cranes and crawler cranes talking to each other. The anti-collision system means cranes talk to each other without human interference, and they automatically shut down when they are too close to each other,” said Subhi.

A key technological advancement is the crane collision prevention system, which means the cranes talk to each other and shut down if they become too close
In addition to ground operations, the project is leveraging aerial technology to mitigate risk in high-altitude work.
“We have used drones for the inspection of the cranes and inspection of the steel structure itself to minimise the risk of working at height,” said Subhi.

Drones have been adopted on-site to mitigate the risk of working at height
Worker welfare
The project’s commitment extends beyond mere regulatory compliance to comprehensive worker welfare, establishing a high standard for construction sites in the region.
With current staffing reaching approximately 11,000 direct and indirect workers, welfare provisions are a core priority, linking directly back to Aramco’s corporate standards.
In a region where extreme heat is a constant challenge, the project has implemented advanced heat stress management protocols. This includes the installation of heat sensors with alarm systems, mandatory work stoppage during peak heat hours and regular briefings on heat exhaustion symptoms. Fully air-conditioned rest areas are provided for breaks and meals.
Aramco is also committed to developing national talent. A significant proportion of the staff are young, and about 20% of the team are women.
The relationship with the joint-venture contractor is defined by collaboration rather than traditional client-contractor hierarchy. “We are one team, working together,” said Subhi. This approach has fostered a cooperative environment that is accelerating the on-site progress towards the 2026 completion goal.
