Dubai prequalifies EPC firms for $22bn tunnels project
2 August 2024
Dubai Municipality has prequalified engineering, procurement and construction (EPC) companies that can bid, along with investor and operation and maintenance (O&M) partners, for the contracts to develop four of the six packages of the $22bn Dubai Strategic Sewerage Tunnels (DSST) project.
Under the current plan, the $22bn DSST project is broken down into six packages, which will be tendered as public-private partnership (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 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.
The prequalified EPC companies for packages J1, J2 and W are:
- Acciona Construccion (Spain) – Dubai branch

J1, J2, W and J3 will comprise the deep sewerage tunnels, links and TPS (TLT) components of the overall project.
Dubai Municipality said the prequalified companies have received the pre-request for proposal phase versions of the technical schedules.
For each EPC contractor, the technical prequalification may be in respect of one or more components – which include deep sewer tunnels, terminal pumping stations and/or link sewers, as applicable – of one or more DSST-TLT packages.
MEED understands the project’s remaining two packages, the expansion and upgrade of the Jebel Ali and Warsan STPs, will be procured in a process separate from the four DSST-DLT components.
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
Unconventional procurement process
In addition to its size, the project is gaining significant interest due to its unique procurement approach, whereby EPC contractors’ prequalification precedes developers’ prequalification.
"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," the source said.
"These designs should be ready once the Dubai Municipality completes the prequalification process for investors, saving roughly three months compared to the usual route where the prequalification process for developers and EPC contractors are done simultaneously."
The staggered prequalification process is expected to help ensure the RFP process takes around six months rather than the typical nine-month period.
"It will also encourage a stronger partnership approach to implementing the project's various packages," said the source.
Dubai Municipality recently invited investors and developer firms to submit their statements of qualifications by 5 September for the contracts to develop and operate various packages of the project.
The client is expected to issue the RFP to prequalified investors by the end of September.
The bidders for each of the PPP RFPs will be prequalified consortiums comprised of sponsors, EPC contractors and O&M contractors.
MEED previously reported that 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 sewage treatment plant (STP) treats the flow.
The second catchment, called Jebel Ali, 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.

Diriyah signs land lease deal with King Saud University19 December 2025
Saudi Arabia gigaproject developer, Diriyah Company, has signed a long-term land lease agreement with Riyadh Valley Company, an investment arm of King Saud University.
Diriyah Company will lease 552,000 square metres (sq m) of land from King Saud University for a period of 70 years.
The deal will enable the company to add the land bank to its second phase of the Diriyah Project, which is also known as DG2.
The agreement was signed by Diriyah Company's Group CEO, Jerry Inzerillo, and the acting president of King Saud University and Riyadh Valley Company chairman, Ali Masmali.
Diriyah Company is already developing the area adjacent to King Saud University. In April, it awarded an estimated SR4bn ($1.1bn) contract for a utilities relocation package for the King Saud University project located in the second phase of the Diriyah Gate development (DG2).
The contract was awarded to the joint venture of Beijing-headquartered China Railway Construction Corporation and China Railway Construction Group Central Plain Construction Company.
The scope of the contract covers the design, construction and relocation of KSU's utilities and administration offices, as well as the construction of a district cooling plant, water storage facilities, a sewage treatment plant, a natural gas plant, a diesel transfer pumping station, a utility tunnel, irrigation water storage tanks, office buildings, warehouses and maintenance workshops.
In addition to KSU, DG2 will feature residential developments, hotels, an opera house, the Saudi Museum of Contemporary Art, six academies, an arena and a mosque.
The Diriyah masterplan envisages the city as a cultural and lifestyle tourism destination. Located northwest of Riyadh’s city centre, it will cover 14 square kilometres and combine 300 years of history, culture and heritage with hospitality facilities.

Kuwait to sign Mubarak port agreement next week19 December 2025
Kuwait and China are expected to sign the agreement to develop the subsequent phases of Kuwait’s Grand Mubarak Port next week.
According to media reports, the announcement was made by Kuwait’s Public Works Minister Noura Al-Mashaan on Thursday.
The contract value is estimated to be about KD1.2bn ($4bn).
In May, Beijing-headquartered China Harbour Engineering Company, a subsidiary of China Communications Construction Company (CCCC), signed an early contractor involvement (ECI) agreement with Kuwait to develop the next phases of the project.
The initial works include surveying, investigation, hydrological observation, geophysical exploration, testing, model testing, process simulation, design review, owner inspection, preliminary design of sand-retaining embankments, and on-site services and management.
The project launch ceremony was held in mid-April. It was attended by several high-profile representatives from Kuwait and China, including Fu Xuyin, China’s vice-minister of the Ministry of Transport, Zhang Jianwei, the Chinese ambassador to Kuwait, and Nora Mohammad Al-Mashaan, Kuwait’s minister of public works.
In January, MEED reported that Kuwait’s cabinet had approved a bid from China Communications Construction Company to implement all stages of its Mubarak Al-Kabeer Port project.
The country ramped up its efforts on the project after meetings between Kuwaiti and Chinese officials in June last year.
In 2023, the two countries signed a memorandum of understanding to develop port infrastructure.
Phase one of the project cost $1.2bn and was completed in 2014.
The project’s first phase included site levelling and the development of a marina, quay walls, berths, a navigational terminal and port buildings.
The port is not operational because the phase one works did not include vital equipment such as cranes.
It is understood that the completion of phase two will allow the port to start operations.
The full scope for phase two of the project is expected to include:
- Construction of loading and unloading facilities
- Construction of quay walls and reclamation
- Construction of the container yard and the back of the port
- Infrastructure works
- Construction of buildings
- Construction of a container terminal
- Construction of associated facilities
- Installation of safety and security systems
A third phase is also planned to further expand the port.
The latest developments follow a series of agreements signed in September 2023 to deliver some of Kuwait’s immediate development goals for 2024-28. These agreements will position Chinese companies to play a leading role in the Fourth Kuwait Master Plan 2040.

Metito consortium wins Mecca sewage scheme19 December 2025
A team comprising Metito (UAE), Etihad Water & Electricity Company (UAE) and SkyBridge Company (UK) has been awarded a contract to develop the Hadda independent sewage treatment plant (ISTP) project in Mecca Province, Saudi Arabia.
The contract was awarded by Saudi Water Partnership Company (SWPC), the kingdom’s principal off-taker for water and wastewater public-private partnership (PPP) projects.
The project will be developed on a build-own-operate-transfer basis and is expected to begin operations in 2028, followed by a 25-year operating term.
The plant will provide an initial treatment capacity of 100,000 cubic metres a day and will feature a treated sewage effluent (TSE) reuse system with a storage tank and a 38-kilometre pipeline designed to handle 350,000 cubic metres a day.
Earlier in December, MEED reported that the team had been named preferred bidder at a levelised tariff of SR2.354 ($0.63) a cubic metre.
SWPC selected the Miahona-led consortium as the reserve bidder for this project with the second-lowest submitted bid of SR2.599($0.69) a cubic metre.
According to SWPC, the TSE reuse system accounted for 31% of the preferred tariff for the Arana ISTP and 27% for the Hadda ISTP.
In March last year, SWPC signed a 25-year water-purchase agreement with a team comprising the local Miahona Company and Belgium-based Besix for the contract to develop and operate the Al-Haer ISTP in Riyadh, as part of the third batch of the kingdom’s ISTP programme.
Four months later, the Saudi-listed Power & Water Utility Company for Jubail & Yanbu (Marafiq) joined the developer consortium.
The Miahona/Besix team offered to develop the project for SR1.9407 ($0.5173) a cubic metre, while the second-lowest bid, from a team comprising Spain’s Acciona and the local Tawzea, was SR2.2041($0.588) a cubic metre.

Morocco awards $1bn Casablanca airport terminal deal19 December 2025
Morocco’s National Airports Office (ONDA) has awarded a MD12bn ($1.2bn) contract to build the new terminal at Casablanca’s Mohammed V International airport.
The contract was awarded to the joint venture of local firms Societe Generale des Travaux du Maroc (SGTM) and Travaux Generaux de Construction de Casablanca (TGCC).
Construction work on the Mohammed V International airport expansion is expected to begin immediately.
The project is slated for completion in 2029.
The expansion will cover more than 600,000 square metres (sq m) and increase the airport’s capacity to 30 million passengers a year.
The project is designed by a consortium comprising the local branch of French engineering firm Egis Batiment International, Morocco’s Ala Concept and UK-based RSHP Architects.
The scope of work covers preparatory works, structural works, waterproofing, steel structural works, building facades, electrical, mechanical and plumbing (MEP) works, data centre works, HVAC systems and other associated works.
The tender also covers the construction of a 300-key airside hotel.
The new terminal is expected to be ready in time for the 2030 Fifa World Cup, which Morocco is co-hosting alongside Portugal and Spain.
ONDA tendered the project contract on 4 November, with a bid submission deadline of 16 December, as MEED reported.
In July, ONDA began early works on the new terminal building, awarding an estimated MD294m ($29m) deal for enabling works to local firm Societe de Travaux Agricoles Marocaine.
In January, Morocco’s Transport & Logistics Minister, Abdessamad Kayouh, said that the study to expand the airport’s capacity was nearing completion.
The project is part of Morocco’s MD42bn ($4.3bn) plan to expand key airports in anticipation of increased passenger flow for the 2030 football World Cup.
Morocco plans to upgrade several airports, including those in Tangier, Marrakech and Agadir, increasing their respective annual passenger capacities to 7 million, 16 million and 7 million.
There are also plans to add a new terminal at Rabat-Sale airport, raising its capacity to 4 million passengers annually, and to increase Fez airport’s capacity to 5 million passengers annually.
The new terminal at Mohammed V International airport will be connected to a high-speed train network linking Kenitra to Marrakech.

Batteries shape the region’s energy future18 December 2025

This package also includes:
> TECH THEMES: Key technology themes poised to shape 2026
> EVs: Middle East drives electric vehicle revolution
Batteries, having progressed from enabling consumer electronics to powering the first wave of electric vehicles (EVs), are now poised to become one of the world’s most significant industrial and geopolitical forces in the next decade, says GlobalData’s Strategic Intelligence platform.
According to a recently published report, this progress is due to stored energy’s accelerating and expanding role in mitigating climate change.
For the Middle East, a region defined by its energy leadership and major economic diversification strategies, the battery revolution presents not just a commercial opportunity, but a strategic imperative focused on securing key components of the new global supply chain. The region’s success in the coming years will be judged by its ability to navigate the raw material shortages, geopolitical rivalries and technological shifts that define the market.
The cornerstone of this theme is the soaring demand for cheap, safe and high-performance batteries, driven predominantly by the automotive sector, which is forecast to account for over 80% of aggregate battery demand between now and 2035.
Industry growth
Global lithium-ion battery industry revenues are forecast to surge to over $408bn by 2035, up from $88.6bn in 2022.
This growth is spurring industrial expansion, with the global transition to EVs requiring an accompanying build-out of battery gigafactories. While China currently dominates this landscape, accounting for 77% of EV gigafactories in 2022, Europe and North America are taking steps to reduce their dependence on Chinese supply chains by 2030, driven by the US Inflation Reduction Act and European ambition.
This geopolitical tension directly impacts the Middle East’s emerging industrial strategy. The need for regionalised supply chains is critical, and North Africa has already taken a step towards this with Chinese investment establishing a battery gigafactory in Morocco, aimed at supplying the European market.
Furthermore, Gulf nations are exploring direct investment in manufacturing capability, demonstrated by the Statevolt plan to build a $3.2bn gigafactory in the UAE’s northern emirate of Ras Al-Khaimah, specialising in advanced battery cells.
These efforts are essential to integrating the Middle East into the global manufacturing network, leveraging its geographical position between the major consuming markets of Europe and Asia.
Beyond manufacturing, the most significant threat to the industry is the impending shortage of low-cost, easy-to-purify raw materials like lithium, cobalt and nickel, which is largely due to a lack of investment in new mines over the past five years.
Lithium extraction, in particular, requires significant investment to meet the growing demand. This crunch has been exacerbated by China’s control over the entire supply chain, from the mines to the refining of critical battery metals.
This situation is as much an environmental and geopolitical concern as it is an economic one, necessitating a shift towards a circular battery economy. The region, therefore, has an immediate need to invest in recycling facilities to offset near-term supply shortages, securing local access to processed materials for its emerging domestic battery production capabilities.
Green hydrogen capacity in the region is projected to grow at a compound annual growth rate of nearly 150% in 2025-30
Clean energy edge
The Middle East’s position as a source of clean energy and a major energy exporter makes the deployment of hydrogen fuel cells a crucial complementary theme. Hydrogen has been championed for decades as a clean fuel, and a UN-sponsored Green Hydrogen Catapult Initiative, involving Saudi and European founding partners, aims to scale up green energy production.
The Middle East is pursuing this with projects like Dubai’s Green Hydrogen project, which uses solar power to produce hydrogen, signalling the region’s intention to be a major player in clean fuel production.
Though hydrogen is unlikely to power small vehicles like cars, its future dominance is expected in heavy industrial processes and heavy transport, such as lorries, trains, ships and planes, making it highly relevant to the Gulf’s core logistics and industrial sectors.
Green hydrogen capacity in the region is projected to grow at a compound annual growth rate of nearly 150% in 2025-30, although this starts from a low base.
Finally, the shift towards battery-powered EVs appears to be gaining regional momentum. Although EV adoption in the Middle East is still in its early stages – with the UAE leading with just a 3% penetration of new car sales – projections show EVs could account for as much as 64% of the new car market by 2035. The transition is supported by major investment in charging infrastructure and a market poised to be worth tens of billions of dollars.
Impending consumer demand will be a primary driver for the strategic battery manufacturing and hydrogen production investments now being made by policymakers and industrial leaders in the GCC. The confluence of these factors – securing the raw materials, establishing domestic manufacturing and deploying complementary clean fuels like hydrogen – will be central to the Middle East’s role in the global energy transition over the next decade.
