EPC teams start forming for $22bn Dubai tunnels
24 September 2024
Register for MEED's 14-day trial access
Some prequalified engineering, procurement and construction (EPC) companies for the contracts to develop and operate various packages of the $22bn Dubai Strategic Sewerage Tunnels (DSST) project have started forming teams in anticipation of the next stage of the tendering process.
In August, Dubai Municipality prequalified 21 companies and consortiums that can bid for three packages known as J1, J2 and W, and 19 for a fourth package known as J3, of the six-package project.
Some companies are in the process of finalising their partners, while at least one has said it does not intend to tap a partner.
While the country of origin is expected to play a role in the formation of teams, it is expected that the complementarity of the companies' expertise and resources will be crucial in the selection process.
The client and its advisers have opted to prequalify EPC contractors ahead of investors in a departure from the classic public-private partnership (PPP) procurement process.
"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," a source familiar with the project recently told MEED.
He added: "These designs should be ready once Dubai Municipality completes the prequalification process for investors, saving roughly three months compared to the usual route, where the prequalification processes for developers and EPC contractors are done simultaneously."
The staggered prequalification process is expected to help ensure the request for proposals process takes about six months rather than the typical nine months.
Six 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.
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 10 kilometres (km).
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.
J1, J2, W and J3 will comprise the deep sewerage tunnels, links and TPS (DLT) components of the overall project.
The project’s remaining two packages entail the expansion and upgrade of the Jebel Ali and Warsan sewage treatment plants (STPs), and will be procured in a process separate from the four DSST-DLT components.

Market-sounding
Dubai Municipality is expected to hold a market-sounding event for investors, MEED reported in early September .
The event is set to take place during the first week of October, a few weeks before interested investors submit their statements of qualifications (SOQ) for the projects' various packages.
MEED previously reported that the client had extended the SOQ submission deadline from 5 September to 21 October.
Gravity system project
The DSST 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 STP treats the flow.
The second catchment 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.

Oman’s Barka 5 IWP solar plant begins full operations1 May 2026
Spain’s GS Inima has begun permanent operations at the solar photovoltaic (PV) plant serving the Barka 5 independent water project (IWP) in Oman.
The solar facility is the third of its kind in Oman to power a large-scale desalination facility through a self-supply model.
In a statement, GS Inima said it will provide up to 50% of the desalination plant’s electricity needs during daytime operations, improving efficiency and reducing reliance on external power sources.
The PV plant has an installed capacity of 6.5MWp. It is designed to optimise energy consumption at the adjacent reverse osmosis desalination facility.
The project was developed by GS Inima in collaboration with local firm Nafath Renewable Energy as the engineering, procurement and construction (EPC) contractor. China-based OCA Global provided owner’s engineering services.
The Barka 5 IWP has a desalination capacity of approximately 100,000 cubic metres a day.
GS Inima won the contract to develop the Barka 5 IWP project in November 2020. As previously reported, financial close was reached in 2022, and construction of the facility was completed in 2024.
The self-supply solar PV plant is equipped with 10,504 bifacial modules supplied by China’s Jinko Solar. These are mounted on fixed structures provided by Mibet Energy.
Power is managed through 18 Sungrow inverters with a total capacity of 320kWac each, while electricity is fed into the desalination plant through an 11kV connection.
The integration of solar power supports the efficiency of the Barka 5 facility, which has an energy consumption rate of 2.7kWh per cubic metre.

Qiddiya receives high-speed rail PPP prequalifications1 May 2026
Register for MEED’s 14-day trial access
Saudi Arabia’s Royal Commission for Riyadh City, in collaboration with Qiddiya Investment Company (QIC) and the National Centre for Privatisation & PPP, received prequalification statements from firms on 30 April for the public-private partnership (PPP) package of the Qiddiya high-speed rail project in Riyadh.
This follows the submission of prequalification statements for the engineering, procurement, construction and financing (EPCF) package on 16 April, as reported by MEED.
The prequalification notice was issued on 19 January, and a project briefing session was held on 23 February at Qiddiya Entertainment City.
The Qiddiya high-speed rail project, also known as Q-Express, will connect King Salman International airport and the King Abdullah Financial District (KAFD) with Qiddiya City. The line will operate at speeds of up to 250 kilometres an hour, reaching Qiddiya in 30 minutes.
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 and travel to the New Murabba development, King Salman Park, central Riyadh and Industrial City in the south of the city.
In November last year, MEED reported that more than 145 local and international companies had expressed interest in developing the project, including 68 contracting companies, 23 design and project management consultants, 16 investment firms, 12 rail operators, 10 rolling stock providers and 16 other services firms.
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, and Ashurst 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.

Bid deadline extensions hint at tighter project market1 May 2026
Commentary
Mark Dowdall
Power & water editorThere has been a steady run of bid deadline extensions across major power and water projects in recent weeks.
The latest is the Al-Dibdibah and Al-Shagaya solar independent power producer (IPP) plant in Kuwait, where the submission date has been moved again to 31 May, following an earlier shift from February to the end of April. Similarly, bidding for the first phase of the Al-Khairan IWPP has also been extended.
In Bahrain, bidding for the 1.2GW Sitra IWPP has been pushed back by another month to 17 May, having already been under main contract tender since last August.
Meanwhile, in Dubai, contractors have been given additional time to submit bids for both the Jebel Ali sewage treatment plant expansion and a dams rehabilitation project in Hatta.
Individually, these shifts are not unusual, and extensions are a routine part of the procurement cycle, especially with large, capital-intensive schemes.
However, amid regional tensions and increasingly complex risk profiles, stakeholders are having to weigh up how much they can absorb, whether that is performance guarantees, financing exposure or delivery risk.
For contractors and developers, this could mean looking more closely at supply chains, insurance costs and the potential for disruption. Lenders, too, are likely taking a more measured view on long-term exposure.
This caution can show up in the bid process. More internal approvals, more conservative pricing, and in some cases, perhaps a hesitation to commit altogether.
At the same time, strong pipelines across the GCC mean contractors are not short of work. Firms can afford to be selective, focusing on projects where risk and return are better aligned.
Clients, in turn, face a choice. Push ahead with more limited competition or extend and try to draw in stronger participation. Most appear to be opting for the latter.

Saudi Arabia launches $2bn Jawharat Al-Arous project1 May 2026
Saudi Arabia has launched Jawharat Al-Arous, an SR8bn ($2bn) private-sector-led residential development in north Jeddah.
The scheme covers 107 million square metres and comprises 18 residential neighbourhoods planned to accommodate more than 700,000 residents. It will provide more than 80,000 residential and commercial plots.
The masterplan also includes 41 government-backed infrastructure and service zones to support large-scale urban expansion.
The project was unveiled by Mecca Region Governor Khalid Al-Faisal and will be overseen by Saud Bin Mishaal Bin Abdulaziz.
According to a recent report by real estate firm Cavendish Maxwell, Jeddah’s residential stock stood at about 1.09 million units at the end of 2025, following the completion of around 4,000 units that year.
An expanding pipeline of about 18,000 units in 2026 and 22,000 units in 2027 is expected to bring total stock to around 1.14 million units by 2027, gradually adding supply without destabilising market equilibrium.
GlobalData expects the Saudi construction industry to grow by 3.6% in real terms in 2026, supported by increased foreign direct investment (FDI) and investment in the housing and manufacturing sectors.
The residential construction sector is forecast to grow by 3.8% in real terms in 2026 and to record an average annual growth rate of 4.7% between 2027 and 2030, supported by Saudi Vision 2030’s goal of increasing homeownership from 65.4% in 2024 to 70% by 2030, including through the delivery of 600,000 homes by 2030.

Damage to US bases in region expected to cost more than $15bn1 May 2026
The $25bn estimate a Pentagon official gave US lawmakers on 29 April did not include the cost of repairing damage to US bases in the Middle East, and the real cost of the war is likely to be between $40bn and $50bn, according to CNN.
That would put the cost of repairing bases and replacing destroyed assets at between $15bn and $25bn.
Jules Hurst III, the Pentagon official serving as the agency’s comptroller, told the House Armed Services Committee that “most” of the $25bn he cited had been spent on munitions. Defence Secretary Pete Hegseth declined to say whether the figure included repairs to damaged US bases.
Iranian strikes across the Gulf in the early days of the war significantly damaged at least nine US military sites in 48 hours, hitting facilities in Bahrain, Kuwait, Iraq, the UAE and Qatar.
Six US servicemembers were killed in an attack on a command post in Kuwait, and 20 more were injured.
Three sources told CNN that the figure provided to the House Armed Services Committee did not include the cost of rebuilding US military installations and replacing destroyed assets.
One source said the true cost would likely be between $40bn and $50bn.
US contractors such as KBR and Fluor, as well as local firms, are likely to be among the leading contenders for contracts to repair and rebuild US bases in the region.
