Dubai extends $22bn tunnels investor prequalification

28 August 2024

Dubai Municipality has set a new deadline for firms to submit their statements of qualifications (SoQs) for the contracts to develop and operate various packages of the $22bn Dubai Strategic Sewerage Tunnels (DSST) project.

According to a source close to the project, interested companies have until 21 October to submit their SOQs, which is six weeks later than the initial submission date of 5 September.

The investor prequalification process for the scheme, which is being procured on a public-private partnership (PPP) basis, comes after the client prequalified engineering, procurement and construction (EPC) contractors that can partner with the developers or investors to bid for the contracts.

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.

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, 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-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 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 the expansion and upgrade of the Jebel Ali and Warsan sewage treatment plants (STPs).

The prequalified EPC companies for packages J1, J2 and W are:

  • Acciona Construccion (Spain) – Dubai branch

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.

The packages for the expansion and upgrade of the Jebel Ali and Warsan STPs will be procured in a process separate from the four DSST-DLT components.

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 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.

    2 April 2026

    Saudi Arabia’s Ministry of Municipalities & Housing, in collaboration with the National Centre for Privatisation & PPP (NCP), has issued an expression of interest (EOI) notice for a contract to develop and operate municipal food safety laboratories under a public-private partnership (PPP) framework.

    The project will be delivered on an equip, operate, maintain and transfer basis, with a contract duration of five years.

    The EOI was issued on 1 April, with a submission deadline of 15 April.

    The project scope covers the equipping, operation and maintenance of municipal food safety laboratories across five municipalities: Hafr Al-Batin, Northern Borders, Tabuk, Qassim and Al-Ahsa.

    Key objectives include upgrading laboratory equipment, expanding chemical and microbiological testing capacity for food and water products, and enhancing testing accuracy to support laboratory compliance across the value chain. The project also aims to ensure effective knowledge transfer and a structured handover to the relevant municipalities at the end of the contract term.

    NCP said in a statement: “The project is intended to strengthen public health and safety standards for citizens and residents of the kingdom in alignment with Saudi Vision 2030, while developing the municipal monitoring ecosystem, optimising food and water testing services, and enabling private sector participation in accordance with global best practices.”

    In October last year, NCP highlighted the scale and diversity of opportunities in the kingdom’s PPP pipeline.

    “At the moment, we have around 200 projects in the pipeline with a total value of roughly $190bn,” said Salman Badr, executive vice president – infrastructure advisory, NCP, during a MEED webinar.

    The projects are spread across 17 sectors. “We have a very sizable programme, and it reflects the breadth of the kingdom’s transformation agenda,” he said.

    NCP was established in 2017. It serves as the central authority and catalyst for designing and implementing privatisation and PPP projects across the kingdom.

    When the first missiles and drones were fired at the GCC on 28 February, the region’s economic story pivoted abruptly, from long-term vision-building to near-term resilience.

    The conflict is now the Gulf’s most consequential economic stress test in a generation. It is challenging the safe haven premium that underpins capital inflows, while disrupting the physical networks that keep the region’s economies running, from energy exports and shipping lanes to airports and tourism.

    MEED editor Colin Foreman asks whether the GCC can sustain investor confidence as energy assets, trade routes, airports and banks absorb the shock. Read more here.

    April’s market focus is on Saudi Arabia, where the Iran war is compounding the logic behind the kingdom’s strategic pivot in its investment plans.

    This edition also includes MEED’s 2026 GCC contractor ranking, in which Chinese firms have surged to the top as Saudi spending cuts and geopolitical risks weigh on GCC construction activity.

  • Consultants submit bids for Al-Maktoum airport metro link

    2 April 2026

     

    French firm Egis has emerged as the lowest bidder for the design contract for the Route 2020 extension, which will start from the Expo 2020 metro station and connect with Al-Maktoum International airport’s West Terminal.

    Egis submitted the lowest bid, priced at AED232.6m ($63.3m).

    The other bidders are:

    • Halcrow International (UK): $66.4m
    • Parsons (US): $71.3m
    • Aecom (US): $82.6m
    • Surbana Jurong (Singapore): $106m

    The extension to the line will run for about 3 kilometres (km) and will feature two stations.

    MEED understands that the invitation to bid was issued in January with a submission deadline of mid-March.

    The existing Route 2020 metro link is a 15km-long line that branches off the Red Line at Jebel Ali metro station. The line comprises 11.8km of elevated tracks and 3.2km of tunnels, and has five elevated stations and two underground stations.

    The Roads & Transport Authority (RTA) awarded the AED10.6bn ($2.9bn) design-and-build contract for the project to a consortium of Spain’s Acciona, Turkiye’s Gulermak and France’s Alstom in 2016.

    Dubai’s plans for its metro network do not stop with connecting the extension of the Route 2020 metro line to Al-Maktoum International airport. There are long-term plans for further extensions.

    Other metro projects

    In October last year, MEED exclusively reported that the RTA had selected US-based engineering firm Aecom to provide consultancy services for the upcoming Dubai Metro Gold Line project, also known as Metro Line 4.

    The Gold Line will start at Al-Ghubaiba in Bur Dubai. It will run parallel to – and alleviate pressure on – the existing Red Line, before heading inland to Business Bay, Meydan, Global Village and residential developments in Dubailand.

    The other metro lines in the pipeline are the Purple Line and the Pink Line, both of which are in the early stages of development.

    Firms are also bidding to update the emirate’s rail masterplan. In October 2025, MEED reported that 10 firms had submitted offers to undertake the project.

    The rail masterplan study will update and modify the RTA’s rail network, which includes the Dubai Metro and Dubai Tram. These plans will support Dubai’s 2040 urban masterplan, which aims for all residents to be within a 30-minute metro or light-rail trip to their place of work. 

    The existing network includes the Red and Green lines of the Dubai Metro and the Dubai Tram, which connects Al-Sufouh and Dubai Marina to the metro network. The last rail project to start operations in Dubai was the Red Line extension that opened for Expo 2020.

    There are also existing and planned rail lines connecting Dubai to other emirates that are being developed and operated by Abu Dhabi-based Etihad Rail. These include passenger and freight services as well as a high-speed rail connection.

    In December 2024, the RTA awarded a AED20.5bn main contract for the Dubai Metro Blue Line project to a consortium of Turkish firms Limak Holding and Mapa Group and the Hong Kong office of China Railway Rolling Stock Corporation.

    The Blue Line consists of 14 stations, including three interchange stations at Al-Jaddaf, Al-Rashidiya and International City 1, as well as a station in Dubai Creek Harbour. By 2040, daily ridership on the Blue Line is projected to reach 320,000 passengers. It will be the first Dubai Metro line to cross Dubai Creek, doing so on a 1,300-metre viaduct.

  • Chevron to drill two gas wells in Egypt before 2027

    2 April 2026

    Chevron is planning to drill two new gas wells this year, one in the Narges field and another in the Western Mediterranean, according to Clay Neff, the president of exploration operations at the company.

    The well in the Western Mediterranean area is due to be drilled in partnership with the London-headquartered oil and gas company Shell.

    Egypt and the broader East Mediterranean region will be core pillars of Chevron’s investment roadmap over the coming years, Neff said.

    He also said that the investments in Egypt reflected the Eastern Mediterranean’s growing strategic importance within Chevron’s global portfolio

    According to Neff, Chevron is aiming to increase its operational production capacity in the region by as much as 50% over the next five years, something that is expected to strengthen cash generation and enhance profitability from its regional operations.

    Chevron’s presence in Egypt dates back nearly nine decades, beginning in 1937 with the distribution of petroleum products before expanding into exploration and production activities in recent years.

    The company currently produces more than 2 billion cubic feet of gas a day across the Eastern Mediterranean.

    Chevron is advancing broader expansion initiatives in the Eastern Mediterranean region that include modernising existing facilities and increasing production capacity, alongside ongoing engineering and design work on the Aphrodite gas field in Cyprus.

    A recently signed government agreement enables the construction of a subsea pipeline connecting Cyprus directly to Egypt.

    Neff said the company is targeting an early final investment decision on the project next year, expressing confidence that close cooperation between Cairo and Nicosia will support timely progress.

    He emphasised that meeting domestic and regional energy demand remains the company’s top priority before directing additional supplies toward export markets in Europe or elsewhere.

    Neff said that Egypt’s well-developed energy infrastructure, particularly its pipeline network and liquefaction plants, provided a strategic edge, adding that new discoveries and capacity expansions will gradually support higher export volumes while safeguarding local supply needs.

    The comments from Neff come shortly after it was announced that the UK oil and gas company BP was making progress with its campaign to drill five wells in Egypt’s portion of the Mediterranean.

    BP’s Fayoum 4 well is scheduled to start production in July, with an estimated output of around 100 million cubic feet of gas a day.
