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.

  • Etihad Rail to begin passenger rail operations from 30 June

    26 June 2026

    Abu Dhabi’s Etihad Rail is set to begin passenger rail operations on 30 June 2026, launching an introductory operational phase on the Abu Dhabi-Fujairah route. Tickets are already on sale through the operator’s digital platforms.

    The passenger roll-out marks a major milestone for Etihad Rail, the developer and operator of the UAE’s National Rail Network. Established in 2009, the company was tasked with delivering a roughly 900-kilometre railway linking key cities, ports and industrial hubs from Ghuwaifat to Fujairah on the eastern coast.

    The launch comes less than five years after the UAE announced its ambition to create a national passenger railway under the country’s “Projects of the 50” programme, which aims to support economic diversification and sustainable development.

    According to Etihad Rail, passenger services will be introduced in planned phases through 2026 and 2027:

    • 23 June 2026: Passenger tickets went on sale via the Etihad Rail app and a dedicated booking website (as well as the contact centre for certain fares)
    • 30 June 2026: Introductory operational phase begins with services between Abu Dhabi and Fujairah only
    • 30 September 2026: Passenger rail services formally commence and expand to include Abu Dhabi, Dubai, Al-Dhaid and Fujairah
    • 30 December 2026: Services extend to Al-Dhafra stations
    • 30 March 2027: Services expand further to include Sharjah

    Customers can book tickets up to four weeks before travel. Tickets for new destinations will be released in line with the phased roll-out.

    Once fully operational, Etihad Rail’s passenger service will connect 11 cities and regions across the UAE, supported by a station network that links key urban and economic centres. The station list includes:

    • Abu Dhabi – Mohamed Bin Zayed City Station
    • Dubai – Al-Yalayis Station
    • Sharjah – University City Station
    • Fujairah Station
    • Al-Dhaid Station
    • Al-Dhannah Station
    • Madinat Zayed Station
    • Liwa Station
    • Al-Mirfa Station
    • Al-Sila Station
    • Al-Faya Station

    For the initial Abu Dhabi–Fujairah service starting 30 June, Etihad Rail said fares will start from AED55 for Comfort class and AED120 for Premium class. The operator added that future fares and routes will be announced separately.

    The operator will offer two travel classes:

    • Comfort: guaranteed seating, Wi‑Fi, power at every seat and luggage space
    • Premium: wider reclining seats, extra legroom and complimentary refreshments

    Within each class, passengers can choose from three fare types based on flexibility:

    • Saver: lowest fare for fixed plans; available only via the app, booking website and contact centre
    • Value: includes complimentary seat selection and ticket changes
    • Flex: includes seat selection, ticket changes and refunds

    Etihad Rail said introductory fares are designed to encourage early uptake and will be available for a limited period, with pricing expected to transition “towards a more advanced fare structure and, ultimately, a broader fare framework” as the service matures.

    Etihad Rail’s passenger trains will have a maximum speed of 200km/h and, once fully operational, each train will carry up to 400 passengers, with an expected annual ridership of about 10 million.

    The journey times are as follows:

    • Abu Dhabi to Fujairah: 105 minutes
    • Abu Dhabi to Dubai: 57 minutes
    • Dubai to Fujairah: 69 minutes

    Train features include generous legroom, Wi‑Fi, power at every seat, foldable tray tables, overhead storage, space for larger baggage and accessibility provisions. Station features include clear signage, comfortable waiting areas, staff assistance, accessibility features and parking.

    Etihad Rail said the onboard experience is designed around “comfort and time well spent”, enabling passengers to work, relax or switch off in a “calm and spacious environment” with guaranteed seating, Wi‑Fi and charging points.

    Etihad Rail’s network currently supports freight operations across 11 terminals and four major ports, underpinning supply chain efficiency, emissions reduction and national connectivity.

    The company also pointed to the broader economic value of the UAE Railway Programme, stating that it creates opportunities worth AED200bn, while passenger rail is expected to generate around AED91bn in economic and social benefits over the next 50 years, driven by faster, safer and more efficient travel.

    Etihad Rail also differentiated the new passenger service from the UAE’s future high-speed rail plans, saying passenger rail is intended to connect more communities across the country with an affordable and comfortable service, while high-speed rail is being designed for “very fast journeys between central points of our major cities”, describing the two as “different products and services designed for different types of journeys”.

  • Firms prepare Hudayriat East PPP tunnels advisory bids

    25 June 2026

     

    Abu Dhabi’s Modon Infrastructure, formerly Gridora, has tendered a contract for technical advisory services for the construction of two underwater tunnels connecting the eastern side of Hudayriat Island with mainland Abu Dhabi.

    Consultants have until 26 June to submit their proposals.

    The project includes the construction of a 4.8-kilometre (km) highway, with four lanes in each direction, connecting Hudayriat Island to Mussafah 8th Street.

    The project will be delivered on a public-private partnership (PPP) basis in coordination with the Abu Dhabi Department of Municipalities and Transport and the Abu Dhabi Investment Office.

    The contract term is expected to be 25 years.

    The latest infrastructure development in Abu Dhabi follows Modon Infrastructure’s invitation in May for firms to register for the next phase of Abu Dhabi’s Mid Island Parkway Project (MIPP), which will also be developed on a PPP basis.

    Modon Infrastructure will act as the lead developer, holding the majority equity stake in the project company. It will award the engineering, procurement and construction contract, as well as the operations and maintenance services and advisory appointments.

    The second phase of the MIPP involves the construction of about 11km of highways, including a mix of three-, four- and five-lane sections. The highways will connect the Um-Yifeenah, Al-Jubail, Al-Sammaliyyah and Sas Al-Nakhl islands to Khalifa City and the E10 road.

    The scope also covers the construction of three interchanges: the E20, E10 and Dumbbell interchanges on Al-Sammaliyyah Island.

    The project includes several major structures, such as the E20 interchange, which will feature cast-in-place box-girder and void-slab bridges, and the E10 interchange with cast-in-place box-girder bridges. It also includes I-girder bridges between Raha Beach West and Sas Al-Nakhl Island, as well as a causeway at Sas Al-Nakhl Island.

    Further key elements include a cast-in-place balanced cantilever bridge between Sas Al-Nakhl Island and Al-Sammaliyyah Island; a tunnel between Al-Sammaliyyah Island and Bilrimaid Island; and a cut-and-cover (open) tunnel on Bilrimaid Island. The project will be completed with another tunnel connecting Bilrimaid Island to Um-Yifeenah Island.

  • Red Sea Global tenders King Salman Bay construction work

    25 June 2026

     

    Saudi gigaproject developer Red Sea Global (RSG) has tendered a contract inviting firms to undertake marine infrastructure works at King Salman Bay on the Red Sea coast, north of Jeddah.

    The scope includes dredging and earthworks, as well as quay wall and edge protection works spanning about 11 kilometres.

    The bid submission deadline is 31 July.

    King Salman Bay is expected to be a waterfront development aimed at reshaping the city’s northern Red Sea frontage into a mixed-use destination, anchored by public-realm improvements and leisure-led development.

    The update follows RSG’s award of an estimated SR100m ($27m) contract to construct a solid waste management centre at its Red Sea Project. The scope includes four buildings: a material recycling facility, a transfer station, an administration building and a vehicle maintenance building.

    In October last year, MEED reported that RSG had secured a SR6.5bn ($1.7bn) credit facility to further develop Amaala, its luxury tourism destination on Saudi Arabia’s northwestern Red Sea coast.

    According to an official statement, “The funding is led by Riyad Bank as the sole underwriter, along with Saudi Investment Bank and Bank Al-Bilad as mandated lead arrangers.

    “The loan arrangement comprises a mix of conventional and Islamic financing and adheres to RSG’s Green Loan Framework, which was first established when it secured private funding from a consortium of four banks for the Red Sea destination in 2021,” the statement added.

    The announcement followed RSG’s opening of its first properties for sale at Amaala, including branded residential communities and a five-bedroom villa on a private island.

    Kuwait’s oil and gas sector has been in crisis in recent months due to disruption from the regional conflict that started after the US and Israel attacked Iran on 28 February 2026.

    A preliminary peace agreement between the US and Iran, which was announced on 14 June, has increased optimism that disruption to the sector will decrease in the coming weeks.

    Under the terms of the agreement, both sides have stated that the free flow of vessels will be permitted through the Strait of Hormuz, through which nearly all of Kuwait’s crude oil is normally exported.
