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.

  • Kuwait receives bids for Al-Khairan phase one IWPP

    2 June 2026

     

    Two developer consortiums have submitted bids for the first phase of Kuwait’s Al-Khairan independent water and power producer (IWPP) project, according to a source.

    Bids were received by the Kuwait Authority for Partnership Projects (Kapp) on 1 June.

    The facility will have a capacity of 1,800MW and 150,000 cubic metres a day of desalinated water. It will be located in Al-Khairan, adjacent to the Al-Zour South thermal plant. 

    The bidders include:

    • Abu Dhabi National Energy Company (Taqa) / A H Al-Sagar & Brothers (Saudi Arabia) 
    • Acwa (Saudi Arabia) / Gulf Investment Corporation (Kuwait)

    The Al-Khairan IWPP is being procured by Kapp in partnership with the Ministry of Electricity, Water & Renewable Energy (MEWRE).

    The main contract was tendered last September. Three consortiums and two individual companies were previously prequalified to participate in the tender.

    Ernst & Young, BNP Paribas, AtkinsRealis and Addleshaw Goddard are financial advisers on the project. Chadbourne & Parke is acting as legal adviser.

    The winning bidder will sign a set of public-private partnership agreements covering financing, design, construction, operation and transfer of the project. The energy conversion and water-purchase agreement is expected to cover a 25-year supply period.

    Future phases

    The Al-Khairan IWPP project is expected to run on low-sulphur fuel oil as the primary fuel and to accommodate crude oil, gas oil and natural gas as backup fuels. Future phases will further expand capacity.

    It is understood that the estimated $750m second phase of the Al-Khairan IWPP project will add a further 1,800MW of generation capacity through a combined-cycle gas-fired power plant.

    The project, first mooted over a decade ago, remains in the early development stages, with no plans currently to advance to procurement in 2026, a source said.

    According to the source, the immediate focus is on advancing plans for the 3,600MW Nuwaiseeb power and water desalination IWPP project.

    The Nuwaiseeb IWPP plant will have a desalination capacity of 75 million imperial gallons a day.

    Kapp plans to release a transaction advisory tender for the project by the end of the year.

  • Doosan confirms Saudi Jafurah 2 cogen contract

    2 June 2026

    South Korea’s Doosan Enerbility has confirmed it has signed an engineering, procurement and construction (EPC) contract worth about $556m for the second phase of the Jafurah combined heat and power (CHP) plant in Saudi Arabia.

    The project is being developed by Korea Electric Power Corporation (Kepco) in partnership with Saudi Aramco.

    Doosan said the contract covers design, equipment supply, installation, construction and commissioning of the facility.

    The Jafurah CHP phase 2 project will be built near the Jafurah gas field, about 400 kilometres east of Riyadh. Once operational, it will generate 330MW of electricity and produce 465 tonnes of steam an hour for the nearby gas field.

    According to the firm, the project’s main steam turbine will be supplied by Doosan Skoda Power, a subsidiary of Doosan Enerbility.

    WSP is acting as the project management consultant for the project, which is scheduled for completion in 2029.

    The Jafurah gas development is part of Aramco’s $3.2bn unconventional resources programme, which aims to develop shale gas in three areas. Jafurah lies southeast of Ghawar, the world’s largest conventional oil field.

    The programme is part of Riyadh’s plans under Vision 20230 to ensure the kingdom remains self-sufficient in gas supply amid rising demand from the residential and industrial power sectors.

    Jafurah phase one

    In February 2025, MEED exclusively reported that talks were under way to expand the capacity of the $500m Jafurah cogeneration independent steam and power plant (ISPP).

    Construction works were completed on the facility last November.

    At the time of its procurement, the plant’s first phase was to have a power capacity of 270-320MW, and a low-pressure (LP) steam demand of 77-166 thousand pounds an hour (klb/hr) and high-pressure (HP) steam demand of 29-126 klb/hour by 2023.

    The LP and HP steam demand will increase to 283-373 klb/hr and 66-321 klb/hr by 2027, respectively.

    The oil giant issued the letter of award to Kepco for the contract to develop the Jafurah ISPP scheme in July 2022.

    Kepco subsequently awarded South Korea’s Doosan Heavy Industries & Construction the project’s EPC contract.

    US/India-based Synergy Consulting provided financial advisory services to Kepco on its bid.

    Sumitomo Mitsui Banking Corporation (SMBC) served as the client’s financial adviser for the project. Germany’s Fichtner Consulting Engineers is technical consultant, while the UK’s Wood Group is project management consultant.

  • Al-Mabanee submits lowest bids for Kuwait infrastructure

    2 June 2026

    Kuwait’s Public Authority for Housing Welfare (PAHW) has opened commercial bids for two major infrastructure and public buildings packages at South Al-Mutlaa Residential City.

    Local firm Al-Mabanee United Company has emerged as the lowest bidder for both contracts, submitting combined offers worth KD44m. Both packages entail the construction, completion and maintenance of services, infrastructure works and public buildings for different district centres within the city.

    The first contract covers the infrastructure and public buildings for the N3 District Centre. PAHW received proposals from eight bidders, with Al-Mabanee United Company submitting the lowest price at KD20.9m. The second-lowest offer was submitted by The Contractor General Trading & Contracting Company at KD22.4m, followed by Golden Engineering Group for General Trading & Contracting at KD22.7m, though Golden Engineering Group was flagged for not providing a bid bond.

    Al-Khonaini General Trading & Contracting Company, operating as Inshat Al-Khonaini, ranked fourth with a bid of KD22.7m, followed closely by Kuwait Industrial Centre Company at KD22.8m. Combined Group Contracting Company submitted a bid of KD23.8m, Al-Dar Engineering & Construction Company bid KD25.7m, and China’s Sichuan Road & Bridge Group Corporation submitted the highest active proposal at KD29m. 

    The second contract is for identical infrastructure and public building works at the N1 District Centre. Al-Mabanee United Company submitted the lowest bid of KD22.8m. Its closest competitor was The Contractor General Trading & Contracting Company, which submitted an offer of KD23.9m.

    Al-Khonaini General Trading & Contracting Company came in third with a bid of KD24.2m, followed by Kuwait Industrial Centre Company at KD24.4m and Golden Engineering Group for General Trading & Contracting at KD24.4m. Combined Group Contracting Company placed a bid of KD26m, Al-Dar Engineering & Construction Company bid KD26.5m, and United Construction Company, known as Al-Inshat Al-Muttahida, submitted an offer of KD 30.9m. Al-Ghanim International General Trading & Contracting filed the highest bid at KD344m and was also noted for lacking a bid bond.

    South Mutlaa Residential City is a large-scale planned development designed to accommodate around 400,000 residents in a modern, fully serviced urban environment. Once completed, it will offer contemporary housing alongside extensive logistical services and a wide range of public and commercial areas, including hospitals, schools and other social services.

    The project also includes major infrastructure works such as approximately 150 kilometres of roads and related structures, lighting and other public works, as well as integrated systems for water distribution, rainwater collection and sewage. In addition, it will provide the civil infrastructure needed for electricity distribution, telecommunications networks and traffic control to support a well-connected, functional city.

  • SLB wins $385m contract for Kuwait oil research centre

    2 June 2026

    Schlumberger Oilfield Eastern, a unit of the US-headquartered oilfield services company SLB, has been awarded a KD118m ($385m) contract to develop an oil and gas research centre in Kuwait.

    The contract was awarded by the state-owned upstream operator Kuwait Oil Company (KOC), according to a report by Kuwait’s Al-Rai newspaper.

    The Ahmadi Innovation Valley (AIV) project is planned as an advanced research and innovation hub equipped with specialised facilities and technical teams focused on applied research for Kuwait’s oil and gas sector.

    The contract was awarded after the Higher Purchase Committee (HPC) of Kuwait’s national oil and gas company Kuwait Petroleum Corporation (KPC) determined the bid to be compliant with the project’s technical and commercial requirements.

    In February 2025, KOC signed memorandums of understanding (MoUs) with five international oilfield service companies to support the development of the AIV initiative.

    These companies were:

    • SLB (US)
    • Baker Hughes (US)
    • Weatherford (US)
    • Halliburton (US)
    • National Energy Services Reunited (US)

    Under the preliminary agreements, each of the five companies agreed to establish a world-class research and development centre at the project site, focused on helping KOC meet challenges in the upstream sector.

    KOC’s CEO Ahmad Jaber Al-Eidan had said in February 2025 that the project will enable Kuwait to keep pace with global transformations while investing in advanced technologies to ensure the sector’s sustainability and achieve operational excellence.
