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.

  • Egypt seeks consultant for major inland waterway study

    18 November 2025

    Egypt’s Transport Ministry has issued an expressions of interest (EOI) request, through the River Transport Authority, to appoint a consultancy firm for a study on a proposed inland waterway linking Lake Victoria to the Mediterranean.

    The consultant will carry out basin-wide data collection and prepare a strategic environmental and social assessment for the project.

    The assignment includes hydrological, topographic, bathymetric and geotechnical surveys across the Nile Basin.

    The consultancy is expected to run for about 15 months, starting in February or March 2026.

    Firms must submit EOIs by 6 December.

    The study forms part of the Vic-Med project, a multi-country plan to establish a continuous inland waterway from Lake Victoria to the Mediterranean Sea.

    The masterplan project aims to reduce transport costs for landlocked countries and provide a lower-carbon alternative to road freight along the Nile corridor

    The work is part of phase two, part one of the feasibility study, funded through a $2m grant from the New Partnership for Africa's Development – Infrastructure Project Preparation Facility (NEPAD–IPPF), the African Development Bank’s (AfDB) fund for early-stage project development.

    The first phase, completed in July 2019 with $650,000 in AfDB funding, developed the project’s legal and institutional framework and launched two regional inland water transport programmes.

    The second phase, valued at $11.7m, covers updated feasibility studies and expanded technical assessments supporting detailed engineering design and cost-benefit analysis in the next stage. 

    This phase also covers the establishment of a regional operating unit for the project in Cairo.

  • Kuwait to make decision on four oil pipeline packages

    18 November 2025

     

    Kuwait is evaluating bids on four packages for a major pipeline project after prices were submitted earlier this month, according to industry sources.

    The four separate packages cover pipeline work in the north, south, east and west regions of the country, sources said.

    Although the total of all bids submitted by Kuwait-based Alghanim International General Trading & Contracting is the lowest at KD419m ($1.4bn), the company submitted the lowest individual bid on only one package, located in northern Kuwait.

    Its bid for the north Kuwait package was KD149.8m ($488.3m).

    Mechanical Engineering & Construction Company submitted the lowest bids for pipeline work on two packages located in the south and east of the country. 

    Both of these bids were valued at KD97,868,394 ($319m).

    Al-Dar Engineering & Construction Company is the low bidder on the fourth package, for pipe work in western Kuwait, submitting a bid of KD64,825,398 ($211.3m).

    Together, all four contracts are expected to be worth about $1.4bn when awarded.

    The scope of all four packages focuses on developing new flowlines and connecting pipelines for oil-producing wells and water wells.

    In some cases, companies are also required to replace old flowlines.

    The contracts are based on work orders, so when KOC needs to connect wells it will issue a request for work execution, industry sources said. 

    Kuwait is trying to boost project activity in its upstream sector.

    The country’s national oil company, Kuwait Petroleum Corporation, is aiming to increase oil production capacity to 4 million barrels a day (b/d) by 2035.

    In August, Kuwait announced that it was producing 3.2 million b/d.

    Earlier this month, KOC said it was planning to spend KD1.2bn ($3.92bn) on its exploration drilling programme through 2030.

  • Indian firm wins Oman chemicals project EPC contract

    17 November 2025

    Register for MEED’s 14-day trial access 

    Indian contractor Nuberg EPC has won a contract to perform engineering, procurement and construction (EPC) works on a project to build chlor alkali and calcium chloride plants in Oman for privately-owned Al-Ghaith Chemical Industries.

    The project involves expanding Al-Ghaith’s existing chlor alkali plant in Sur Industrial City, by adding 120 tonnes a day (t/d) of capacity, taking the unit’s total output capacity to 190 t/d. The project also involves building a calcium chloride plant that will have a production capacity of 80 t/d.

    Nuberg EPC said the contract is being executed on a lump sum turnkey basis, with its scope covering design, front-end engineering and design (feed), detailed engineering, procurement, fabrication, construction, commissioning and handover.

    Project execution is already under way, with completion targeted within 19 months, Nuberg EPC said.

    The project marks the second phase of Al-Ghaith’s integrated chemicals complex in Sur and represents a first-of-its-kind large-scale chlor alkali expansion in Oman.

    Nuberg EPC also performed EPC works on the original chlor alkali plant, which has a capacity of 70 t/d.

    In addition to the Oman project, Al-Ghaith has, in the previous decade, also brought on board Nuberg EPC for its chlor alkali and calcium chloride plants in Abu Dhabi. Those contracts covered the commissioning of a 60 t/d chlor alkali plant that was later expanded to 120 t/d, and the execution of a 125 t/d calcium chloride plant and a 50 t/d carbon dioxide plant.

    Nuberg EPC has also executed the expansion of a 45 t/d chlor alkali plant and a greenfield 80 t/d calcium chloride plant for Oman Chlorine in Sohar, increasing the total chlor alkali output capacity to 75 t/d.

  • Egypt starts production from strategic gas field

    17 November 2025

    Egypt has started gas production from the West Burullus field in the Mediterranean Sea, after connecting the first wells to the national gas grid, according to a statement from the country’s Petroleum & Mineral Resources Ministry.

    Productivity testing showed an output rate approaching 45 million cubic feet a day (cf/d).

    Kareem Badawi, Egypt’s Petroleum & Mineral Resources Minister, said he intends to accelerate development of the field and confirmed that work is under way to connect two additional wells, with the aim of increasing production to 75 million cf/d in the coming months.

    He added that the ministry aims to cut the county’s gas import bill by boosting domestic production.

    The operator of the concession is Cheiron, an Egyptian independent exploration and production company.

    Egypt’s oil ministry said in its statement that the West Burullus field development project represents a model for future integrated projects and investment plans.

    It said that a range of domestic and foreign companies are involved in bringing the field into production.

    In February, a banking consortium led by Banque du Caire, alongside Arab International Bank, Al-Baraka Bank Egypt and Saib Bank, arranged $75m in syndicated medium-term financing for Cheiron Egypt Delta, a subsidiary of the Cheiron Group.

    This financing will help cover part of the investment costs for the gas field development project.

    At the time, Cheiron said that the financing will provide up to 45.5% of the total $165m investment required for the project.

  • Major Iraq refinery project stalls

    17 November 2025

     

    Construction has yet to start on Iraq’s Al-Faw Investment Refinery project due to a range of problems, according to industry sources.

    In May last year, a statement released by the Iraqi Prime Minister’s Office said that Iraq’s state-owned Southern Refineries Company and China National Chemical Engineering Company (CNCEC) had signed a contract to develop the project.

    Iraq’s Oil Ministry previously said the project would be worth $7bn-$8bn.

    One source said: “This project is failing to make progress despite the efforts of senior political figures in the country.”

    A meeting was chaired by Iraqi Prime Minister Mohammed Shia Al-Sudani in August this year to discuss and try to resolve the problems that are stopping the commencement of construction, according to industry sources.

    It is believed that financing remains a key obstacle for the project.

    The Al-Faw project is part of the Iraqi government’s plan to increase Iraq’s refining capacities, attract foreign investment and increase the production of petroleum products domestically.

    The refinery will have a capacity of 300,000 barrels a day and will produce oil derivatives for both domestic and international markets.

    The project will be carried out in two stages.

    The first phase will involve refining operations, while the second will involve constructing a petrochemicals complex with a capacity of 3 million tonnes a year.

    The project also includes the construction of a 2,000MW power plant and the establishment of the Al-Faw Academy for Refinery Technology, to train 5,000 Iraqi workers that will eventually work at the facility.

    Hualu, a subsidiary of CNCEC, signed a preliminary principles agreement for the project in December 2021.

    At the time, Iraq’s Oil Ministry said that the project would have a value of $7bn-$8bn.

    Due to material price inflation since December 2021, some insiders believe that the project value may now be significantly higher.
