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
- Besix Construct (Belgium)
- China Harbour Engineering (China)
- China Railway Group (China)
- China State Construction Engineering Corporation (China)

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.

Kuwait studies two oil export pipelines to bypass Hormuz15 October 2026
State-owned Kuwait Petroleum Corporation is considering developing two oil export pipelines that would bypass the Strait of Hormuz, according to a senior Kuwaiti oil official.
The pipelines would transport crude oil through Saudi Arabia and the UAE, aiming to diversify Kuwait’s export routes.
Mohammed Al-Abduljalil, the deputy chief executive for planning and innovation at the KPC subsidiary Kuwait Oil Company, told Asharq Bloomberg that KPC had agreed with its partners in Saudi Arabia and the UAE to conduct feasibility studies for two separate projects.
The first project extends from Kuwait’s Ahmadi region through Saudi Arabia to the Red Sea coast. The second extends from the Ahmadi region to Fujairah in the UAE.
The pipelines would build on existing infrastructure and, if the plans are approved, are expected to take around four or five years to complete, Al-Abduljalil said.
He said the first project, currently under study, would use the route of the existing East-West pipeline, which connects the kingdom’s eastern oil-producing regions to its western coast.
The second project would follow the UAE’s Habshan-Fujairah pipeline route, enabling oil exports from the Sea of Oman coast, outside the Strait of Hormuz.
Al-Abduljalil emphasised that both projects remain in a very early stage, noting that the agreement to conduct feasibility studies does not constitute a final investment decision to proceed with implementation.

Gulf Spic submits lowest bid for Kuwait booster stations15 October 2026

Kuwait-based Gulf Spic General Trading & Contracting Company has submitted the lowest bid for a contract to upgrade gas booster stations in the country.
Gulf Spic’s bid was worth KD41.2m ($132m) and was one of four bids submitted for the contract.
The project scope focuses on upgrading gas booster stations 140 and 150 (BS-140 and BS-150).
The full list of bidders was:
- Gulf Spic General Trading & Contracting Company, Kuwait – KD41.2m ($132m)
- Combined Group Contracting Company (CGC), Kuwait – KD45.5m ($146m)
- Heavy Engineering Industries & Shipbuilding Company (Heisco), Kuwait – KD50.7m ($163m)
- Alghanim International General Trading & Contracting Company, Kuwait – KD65.5m ($210m)
The project was first announced in 2014. The invitation to bid was issued in May this year, and bids were submitted ahead of the 11 October deadline.
The scope of work on the project covers:
- Upgrade of BS-140 and BS-150
- Replacement of dehydration facilities
- Laying of pipelines
- Installation of safety system
- Construction of associated facilities
Kuwait’s oil and gas sector is currently in the midst of a major crisis, as disruptions to shipping through the Strait of Hormuz have dramatically reduced exported crude oil volumes.
The disruption is also creating significant challenges for oil and gas construction projects, which normally import equipment and materials through the Strait of Hormuz.

Stability holds as project work continues14 October 2026

When Dean McGrail describes the performance of the region’s construction market, he keeps returning to a single word: “stable”.
After initial concerns that the market would experience a sharp downturn and project cancellations following the onset of conflict in the region, regional president McGrail says WSP has yet to see a single major contract cancelled across its regional portfolio.
“We have seen some projects re-evaluated – questions around whether the mix between residential and commercial is right, and whether it should be luxury residential,” he says. “But as of today, we have not seen any projects cancelled, which is a real sign of resilience in the market.”
Under the surface
That resilience does not mean nothing has changed. McGrail is careful to separate re-evaluation from cancellation. Projects already on site and selling into the market are pressing ahead. It is schemes that have not yet been released for off-plan sales that are being paused and reconsidered.
“None of the projects we are currently involved in have been put on hold or suspended,” he says. “It is more re-evaluation. Some of that is investor sentiment, but some of it is materials and logistics as well, which people do not necessarily consider.”
Logistics, in particular, is a pressure that rarely makes the headlines. According to McGrail, shipping disruption has complicated the delivery of heavy equipment on certain schemes. “If we have big pieces of kit coming in – chillers or turbines for a power station – that becomes challenging,” he says.
The bigger question is viability. And while rising material costs, set against softening sales prices, are forcing developers to reappraise the numbers, for now the balance sits firmly on the side of continuity. McGrail estimates that revalidation and feasibility work accounts for less than 3% of the firm’s current order book, with the remainder progressing as normal.
“Requests for proposals have not slowed down across any of our disciplines or business units,” he says. “We are definitely seeing an uptick in infrastructure.”
Infrastructure pivot
That focus points to where McGrail expects the next few years of growth to come from. Rail sits at the centre of the UAE story, alongside road upgrades and other major developments in Abu Dhabi. In Dubai, the clearest signal of intent is the expansion of Al-Maktoum International airport.
“Al-Maktoum is a really good indicator of the future direction of travel,” he says. “That is not a project that is slowing down. There has been a commitment to Emirates that it will move there, and it is still progressing.”
The scale of the airport – and the challenge of relocating an airline the size of Emirates in one move – raises the question of how it will be funded. Here, McGrail returns to the theme of stability and to the mechanism that underpins it.
“One of the beauties of this region is the ability of government to step in,” he says. “They can fund it. If the private sector does start to suffer, that is the backstop. They push money into infrastructure – roads, rail, airports – which keeps our industry moving.”
Saudi reset
In Saudi Arabia, the recalibration story predates the conflict, and McGrail says the change should be read as a strength rather than a retreat.
“I am positive,” he says. “When the reprioritisation started at the beginning of 2025, having lived through the global financial crisis here, I saw the decision to stop, re-evaluate and reprioritise expenditure as a positive. When Vision 2030 was set, Saudi Arabia had not won Expo or the World Cup, so the reprioritisation was the right thing to do. Saudi Arabia will come out of it stronger. Short-term pain, long-term gain.”
The nature of the work is shifting with the budget. McGrail sees the kingdom moving towards a model long familiar in the UAE, in which core infrastructure and a handful of landmark buildings are delivered first, before surrounding plots are carved up and sold on.
“You establish a few key iconic buildings, then the plots on the outside are carved up and they look for external investment to come in and develop them,” he says. “It is no different from Downtown Dubai, where Emaar built the Burj Khalifa and a few buildings, then started selling plots.”
That approach is increasingly tied to public-private partnerships (PPPs), although McGrail is measured on how far the model will stretch.
“PPP is definitely becoming more prevalent on some of the larger infrastructure projects, though still not as significant as it was made out to be when they first started talking about it,” he says. He sees industrials, mining, healthcare and schools as a natural fit, rather than PPP becoming a blanket procurement route.
Aviation is another priority. WSP was recently appointed to the rehabilitation of the existing terminal at Jeddah’s King Abdulaziz International airport, alongside a new terminal. It also recently secured a role on the expansion and upgrade of King Fahd International airport in Dammam.
“Aviation is definitely a key area of focus for us as we head into the next 12, 24, 36 months,” McGrail says.
Beyond the two dominant markets, McGrail sees pockets of activity but no challenge to the balance of the portfolio. In Qatar, he points to a recovery taking shape towards the end of last year, with WSP active on the Qatar Children’s Museum and continuing its long-running work with the Public Works Authority (Ashghal). Oman is generating masterplanning work, including reviving the Blue City scheme.

Gas-fired projects drive resilience in UAE power sector14 October 2026

The $3bn Taweelah C combined-cycle gas turbine (CCGT) project has been the UAE power sector’s standout contract award this year, accounting for the majority of the $4.17bn in awards as of early September.
The total is well below the record $12.02bn awarded in 2025, when Abu Dhabi’s $6bn round-the-clock solar photovoltaic (PV) and battery energy storage system (bess) project lifted the market to record levels. However, 2026 remains broadly consistent with recent years, compared with $5.93bn in 2024 and $3.05bn in 2023.
According to MEED Projects, generation accounted for $3.06bn across three awards, while transmission contracts totalled $1.11bn.
Gas-fired focus
Emirates Water & Electricity Company (Ewec) signed the power-purchase agreement (PPA) for Taweelah C in June with a consortium comprising Abu Dhabi National Energy Company (Taqa), Saudi Arabia’s Al-Jomaih Energy & Water Company and Singapore’s Sembcorp Industries.
The scale of the 2.5GW independent power producer (IPP) provides a useful lens through which to view the wider market. Although the UAE continues to expand solar generation and battery storage, it is still investing heavily in flexible thermal capacity to support rising electricity demand and a grid with significant renewable generation.
Major gas-fired opportunities are also moving into the Northern Emirates, with state utility Etihad Water & Electricity (EtihadWE) preparing to receive offers from five contractor groups for the 2.6GW Al-Zawra CCGT project in Ajman.
The project follows the retirement of EtihadWE’s older 200MW Al-Zawra gas plant in 2023. With Ewec acting as offtaker, the scheme also points to a wider role for EtihadWE in developing large-scale generation.
It is understood that the Ajman project will be the first of at least three planned power plant projects procured by the utility under a new long-term roadmap for future projects across both power and water.
Abu Dhabi’s 3.3GW Al-Nouf IPP is another major gas-fired plant moving towards execution. Japan’s Sumitomo Corporation is expected to formally sign the PPA by the end of the year, while the joint venture of Spain’s Tecnicas Reunidas and Egypt’s Orascom Construction is also set to be confirmed as the engineering, procurement and construction (EPC) contractor.
To put this into context, the deal would make 2026 the second most valuable year for power sector investment on record, eclipsing both 2017 and 2018, when contract awards in the UAE reached $7.39bn and $7.27bn, respectively.
Solar and storage
The UAE’s renewable procurement is increasingly combining solar generation with storage to provide electricity beyond daylight hours.
Dubai Electricity & Water Authority (Dewa) is preparing to award the seventh phase of the Mohammed Bin Rashid Al-Maktoum Solar Park, with Abu Dhabi Future Energy Company (Masdar) submitting the lowest tariff for the project in July.
China’s BYD will act as a bess supplier for the project, which combines 2,000MW of PV capacity with a 1,400MW bess designed to discharge for six hours, equivalent to 8,400MWh of stored energy.
The storage component will allow Dewa to use more solar power after sunset, reducing the gap between daytime generation and the evening demand peak.
The 1,800MW sixth phase is also nearing completion, with Larsen & Toubro delivering the estimated $1.5bn project for Shuaa Energy 4, the project company formed by Dewa and Masdar.
Dewa has increased the planned capacity of the solar park to 7,260MW by 2030, from its earlier target of 5,000MW.
Furthermore, Ewec is advancing its 1.5GW Al-Zarraf solar PV plant, with EDF and Korea Western Power Company selected as the consortium to develop the project.
Grid expansion
Multibillion-dollar IPP schemes have driven annual award values in recent years, while transmission work continues to provide a steadier flow of opportunities for contractors and equipment suppliers.
Transmission awards fell to $1.11bn across 22 packages in 2026, from $2.98bn in 2025, reflecting the absence of a comparable large-scale package rather than a halt in network investment.
Ewec and Taqa are expanding 400kV and 132kV networks across Abu Dhabi and the Northern Emirates, while Dewa continues to reinforce its cable and substation systems in Dubai.
In September, EtihadWE received bids for a contract to carry out a techno-economic feasibility study for a proposed 2GW subsea electricity interconnector with India.
The proposed 1,400-kilometre link would be the UAE’s first direct subsea cross-border electricity interconnector, illustrating a potential longer-term ambition to connect the UAE to wider regional and international power markets.
Earlier this year, the GCC Interconnection Authority awarded Omexom, part of France’s Vinci Group, a contract to build a 400kV overhead transmission line between the UAE and Saudi Arabia.
In October, the UAE and Saudi Arabia signed a memorandum of understanding to advance cross-border electricity interconnection, paving the way for feasibility studies on power exchange, commercial electricity trading and the expansion of the wider GCC interconnection grid.
Waste-to-energy
Waste-to-energy continues to become an increasingly important part of the UAE’s infrastructure pipeline as the country seeks to reduce landfill dependence and diversify its power mix through alternative generation sources.
Dubai Municipality recently invited developers to submit expressions of interest for its planned Jebel Ali waste-to-energy public-private partnership, a greenfield facility designed to treat up to 6,000 tonnes of municipal solid waste a day.
According to a source, the municipality plans to prequalify developers later this year, then issue a request for proposals in the first quarter of 2027.

Riyadh awards $1.5bn metro rolling stock contracts14 October 2026
Register for MEED’s 14-day trial access
Saudi Arabia’s Royal Commission for Riyadh City (RCRC) has signed contracts worth about SR5.5bn ($1.5bn) to procure 94 additional trains for the Riyadh Metro network.
Germany’s Siemens and France’s Alstom have been awarded the contracts. They cover rolling stock manufacture, onboard systems, equipment and related services.
The procurement will increase the metro fleet from 183 to 277 trains. Deliveries are due to begin in phases in 2028, with the additional units subject to testing and operational trials before entering service.
RCRC expects the programme to increase the network’s passenger capacity by 60%.
The additional trains will be distributed across the six metro lines based on current demand and projected ridership.
The Red Line will receive the largest capacity increase, at 142%, followed by the Yellow Line at 116% and the Blue Line at 60%. Capacity on the Orange and Purple lines will increase by 27% and 16%, respectively.
Daily capacity on the Blue Line is set to increase from about 340,000 to 533,000 passengers. Capacity on the Red Line will rise from 154,000 to 370,000 passengers a day, while the Yellow Line will increase from 133,000 to more than 288,000.
The expansion is intended to meet rising demand for public transport as Riyadh prepares to host Expo 2030 and the 2034 Fifa World Cup, alongside continued growth in residential, commercial and entertainment developments.
Speaking at the 37th government press conference, RCRC chief executive Ibrahim Al-Sultan said the metro has carried more than 300 million passengers since it began operating.
Average metro ridership rose by about 25% in the first nine months of 2026 compared with the same period in 2025, he added.
The wider Riyadh public transport system, including buses and the metro, is approaching 500 million passenger journeys.
