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.

Stakeholders aim to sign Iraq pipeline deal by year end6 November 2026

Stakeholders expect a key contract to be signed before the end of the year for the development of a major oil export pipeline network in Iraq, according to industry sources.
Iraq and Syria’s governments, state-owned oil companies and a consortium led by Qatar’s UCC are currently discussing the terms.
If all parties agree to the proposed deal, the UCC-led coalition will become the selected developer responsible for tendering engineering, procurement and construction (EPC) contracts for the project.
The consortium includes US-based Chevron, the investment company TI Capital and France’s TotalEnergies.
The proposed plan will use a fast-track framework to bring the pipelines online as quickly as possible.
One source said: “The plan that is being discussed is highly unusual, because it is such a large-scale pipeline project and it would be brought online in a relatively short timeframe.”
A team from UCC is currently in Iraq for meetings with government officials to discuss the project, one source said.
The project will be focused on four pipeline packages:
- Basra to Najaf
- Najaf to Haditha
- Haditha to Fish Khapour
- Haditha to Banias Port in Syria
In July, Iraq’s cabinet approved state-owned Basra Oil Company signing a ​heads of agreement and a non-disclosure agreement with the UCC-led consortium to explore possible future oil pipeline projects.
Under the terms of the agreement, the consortium is preparing technical and financial feasibility studies for strategic export pipeline projects.
Also in July, US-based KBR was awarded a consultancy contract for the section of pipeline due to extend from Basra to Haditha.
In April, Iraq announced the allocation of $1.5bn for the Basra-Haditha route, while the larger scheme is estimated at around $5bn.

Taqa shortlists 17 contractors for Mirfa-Liwa scheme6 November 2026

Up to 17 contractors have been invited to submit bids for a major water transmission and distribution scheme serving Mirfa, Madinat Zayed and Liwa in Abu Dhabi, a source close to the project has confirmed to MEED.
The project, originally estimated to cost $775m, comprises a water transmission system from Mirfa, alongside distribution networks serving farms and settlements in Abu Dhabi’s western region.
In October, MEED exclusively reported that a request for proposals had been issued, with bids due on 5 January 2027, following an extension from the initial deadline of 11 November 2026.
The Mirfa-Liwa scheme has been in procurement for several years and was previously tendered in December 2024 as an engineering, procurement and construction scheme, divided between transmission and distribution works.
As MEED understands, it was recently re-tendered under a design, build and operate model, extending the contractor’s responsibilities to operating the infrastructure after construction.
According to sources, the full list of contractors invited to bid for the tender includes:
- Afcons Infrastructure (India)
- Alkhorayef Water & Power Technologies (Saudi Arabia)
- China Machinery Engineering Corporation (China)
- China National Chemical Engineering (China)
- China Tiesiju Civil Engineering Group (China)
- Danway Electrical & Mechanical Engineering (UAE)
- Emarat Aloula Contracting (UAE)
- FCC Aqualia (Spain)
- Gulf Contractors Company (UAE)
- Hydropower Energy & General Construction (UAE)
- Jereh Oil & Gas Engineering Corporation (China)
- Mapa (Turkiye)
- Nesma & Partners Contracting Company (Saudi Arabia)
- Orascom Construction (Egypt)
- Power Construction Corporation of China (China)
- Tecton Engineering & Construction (UAE)

Gulf conflict cuts Emirates Group profit by 66%6 November 2026
Dubai’s Emirates Group made a profit before tax of AED4.1bn ($1.1bn) in the first half of its 2026-27 financial year, 66% less than the AED12.2bn it made in the same period last year.
The six months to 30 September were the group’s first full half-year since military activity disrupted commercial air traffic across the Gulf on 28 February. Group revenue fell 12% to AED66.2bn ($18bn), from AED75.4bn a year earlier. Profit after tax fell 66% to AED3.6bn ($1bn).
Earnings before interest, tax, depreciation and amortisation (Ebitda) fell 41% to AED12.5bn ($3.4bn).
The results follow a record 2025-26 financial year. The group made a profit before tax of AED24.4bn in that year, on revenue of AED150.5bn.
“It has been a demanding six months, and once again our business model and our people stood up to the test,” said Sheikh Ahmed Bin Saeed Al-Maktoum, chairman and chief executive of Emirates Airline and Group. “Customer demand held firm and our cargo operations made a strong contribution, keeping revenue and cash levels healthy even as global jet fuel prices doubled against the same period last year.”
Airline performance
Emirates airline’s profit before tax fell 68% to AED3.7bn ($1bn), compared with AED11.4bn a year earlier. Its revenue fell 13% to AED56.9bn ($15.5bn). The airline carried 21.8 million passengers, 22% fewer than a year earlier. Capacity measured in available seat kilometres fell 17%, and the passenger seat factor dropped to 72% from 79.5%.
Cargo partly offset the drop in passenger numbers. Emirates SkyCargo carried 1.2 million tonnes, 1% less than a year earlier, but its revenue rose 52%. The conflict reduced the airfreight capacity available on the market, and disruption to shipping pushed shippers towards air transport.
Before hedging gains, fuel costs rose 60%, even though the airline uplifted 12% less fuel. Gains of AED7.1bn ($1.9bn) from fuel hedging cut the net increase in fuel costs to 13%. Fuel accounted for 34% of operating costs.
On 30 September, Emirates was operating 91% of its pre-disruption network, serving 150 airports in 78 countries and territories. On 31 March, it had been flying 58% of its passenger capacity to 122 destinations in 65 countries.
Fleet investment
The airline received nine Airbus A350s and five Boeing 777 freighters during the period. Its fleet grew to 289 aircraft, from 277 on 31 March. Emirates is continuing its cabin retrofit programme, a planned investment of more than $7bn. It refurbished 12 aircraft in the first half. In May, it broke ground on a $5.1bn engineering and maintenance, repair and overhaul (MRO) facility at Al-Maktoum International airport, which is expected to be completed in the mid-2030s.
The group’s cash position was AED54.1bn ($14.7bn) on 30 September, down from a record AED59.6bn on 31 March. The group said it had used its reserves to make pre-delivery payments for aircraft and to service existing debt. It also paid the remaining AED2bn of the AED3.5bn dividend declared for 2025-26 to its owner, the Investment Corporation of Dubai.
Ground services and travel company dnata made a profit before tax of AED410m ($112m), down 51%. Its revenue fell 7% to AED11bn ($3bn), and the group said dnata’s international businesses helped offset weaker traffic in the UAE.
The group’s workforce fell 2% to 128,237 people.
“We enter the second half of our 2026-27 financial year with measured optimism,” said Sheikh Ahmed.

King Salman airport tenders roads and utilities package6 November 2026

Register for MEED’s 14-day trial access
Saudi Arabia’s King Salman International Airport Development Company (KSIADC) has tendered the Zone C1+C2 roads, bridges and utility networks package for King Salman International airport (KSIA) in Riyadh.
The tender was issued on 26 October, and bids are due by 6 December.
The request for proposals covers the procurement, construction, testing and commissioning of civil infrastructure supporting Terminal 6, alongside the existing Terminals 1-5.
The scope includes upgrades to Airport Road 539, which runs west of Terminals 1-5, and to part of Mohamed Bin Faraj Road 5333, west of Junction 6.
It also includes new roads, ramps, service roads, and signalised at-grade junctions. An additional access road will connect the Terminal 6 site offices to Road 5333.
Structures will include the Junction 6 and Terminal 6 bridges, retaining walls and reinforced-soil structures.
The contractor will also construct the central ground services equipment (GSE) bridge. Before construction begins, the contractor must validate the design, complete any outstanding elements – including mechanically stabilised earth walls, approach slabs, drainage and lighting – and secure the required authority approvals.
Dry utilities will comprise high- and extra-high-voltage containment, a 13.8kV medium-voltage network with package substations, low-voltage distribution and street lighting, and security-surveillance systems.
Wet utilities will include potable water, fire water, irrigation water, treated sewage effluent, district cooling and wastewater networks. Wastewater pipes will range from 200mm u-PVC gravity lines to 1,700mm glass-reinforced plastic mains.
The stormwater network will include channels, culverts, ponds and pipes ranging from 400mm to 1,400mm in diameter. Crossings will be constructed using open-cut excavation, horizontal directional drilling or microtunneling.
Utilities serving the operational terminals will be diverted on a design-and-build basis. Enabling works will include earthworks and the relocation of the security fence and trees. The contractor will also demolish a temporary car park, existing bridges and a sewage pumping station.
Optional works comprise two design-and-build elements that will proceed only at the client’s instruction.
The first is the south GSE bridge. The second is an approximately 1,400-metre, multi-lane access road to the Terminal 6 Transportation Hub, including bridges, underpasses, ramps and tunnels, as well as provisions for future Wadi Loop utilities and structures.

Bahrain construction activity remains subdued5 November 2026

Bahrain’s construction and infrastructure sector remains subdued, with project awards still depressed despite a modest uptick this year.
Data from regional projects tracker MEED Projects shows that $737m-worth of construction and infrastructure contracts had been awarded in the kingdom by 29 October 2026. While this exceeds the $686m recorded across the whole of 2025, it confirms that the market remains in a prolonged downturn.
Between 2016 and 2020, Bahrain recorded more than $2bn in annual awards, peaking at nearly $3.9bn in 2016 when major packages for the Bahrain International airport expansion were signed. Awards then fell to $912m in 2021 before rebounding to almost $2bn in 2022. The recovery was short-lived, with awards declining to $1.66bn in 2023, $1.57bn in 2024 and $686m in 2025.
Major awards
Activity this year has been supported by several housing and transport packages.
The largest award was an estimated $400m contract secured by a joint venture of local developer Naseej and China Machinery Engineering Corporation for the Madinat Khalifa project. Procured under the Mega Government Land Development Programme, the scheme involves the design, financing, construction, marketing and sale of more than 2,500 housing units on two government-owned land parcels, alongside roads and electricity, water, sewage and drainage networks.
Road infrastructure also produced a major commitment. The Ministry of Works amended its award for package four of the Busaiteen Link project, appointing a joint venture of Nass Company and Nasser Hazza Al-Subaei Contracting Company under a BD65m ($172m) contract. The three-year deal replaces a BD69.7m ($185m) award made in January to a consortium of Haji Hassan Group, Saudi Arabia’s Alomaier Trading & Construction Company and Greece’s Terna.
The package includes a signature bridge connecting Muharraq with the North Manama Causeway and Bahrain Bay, as well as road works between junctions four and five.
Residential projects provided further volume. Mohammed Abdulmohsin Al-Kharafi & Sons secured a $112.4m contract to build 512 social apartment units on Madinat Salman’s Island 12. Binaa Al-Bahrain also appointed Kooheji Contractors to build Bayview in Manama, a development comprising four residential buildings and 489 apartments.
Early-stage commitments included a BD5m ($13.5m) consultancy contract awarded to US-based Populous for the planned Sports City at Sakhir. The scope covers the masterplan, internal infrastructure, phase 1A design and tender documents. Lebanon’s Dar Al-Handasah won a QR28m ($7.7m) contract to conduct feasibility studies for the proposed 40-kilometre Qatar-Bahrain Causeway, also known as the Friendship Bridge.
Transport links
Transport is the most promising near-term outlet for the market, with a pipeline valued at about $15bn, according to MEED Projects data.
Cross-border rail has re-emerged as a strategic focus. Bahrain has introduced legislation to establish a framework for constructing, operating, maintaining and regulating railway networks, including licensing, safety, cross-border services, and passenger and freight tariffs.
The move comes as Gulf states prepare to advance the GCC railway network, which is expected to begin operating by the end of 2030. Bahrain’s proposed rail link to Saudi Arabia is expected to run via the planned King Hamad Causeway, a second fixed connection between the two countries alongside the King Fahd Causeway.
Road expansion is also progressing. In September, the Bahrain Tender Board received bids from Nass Contracting, Haji Hassan Group, Almoayyed Contracting Group, Mohammed Abdulmohsen Al-Kharafi & Sons, Eastern Asphalt & Concrete Production, Cebarco Bahrain and Kingdom Asphalt for the upgrade of two kilometres of the Sheikh Jaber Al-Ahmed Al-Sabah Highway. The works involve a four-lane dual carriageway with service roads.
Industrial and maritime infrastructure is advancing, too. The Ministry of Works received five bids for engineering and quantity surveying services linked to reclamation works at Salman Industrial City and Bahrain Logistics Zone.
Dar SSH International Engineering Consultants submitted the lowest offer at BD778,580 ($2.1m), followed by Aecom at $2.2m, Ansari Engineering Services at $2.3m, Millet Engineering Bureau at $2.4m and Ayesa at $2.8m. The project involves reclaiming about 1.13 million square metres of land using 9.67 million cubic metres of fill near Khalifa Bin Salman Port.
The government is also preparing the Bahrain Northern Link Road as a public-private partnership. The 29.5km highway will connect the North Manama Causeway with Suhaila Island and the King Hamad Causeway, creating a parallel east-west route to Sheikh Isa Bin Salman Highway and improving links between Khalifa Bin Salman Port and Saudi Arabia.
Building pipeline
Outside transport, Bahrain’s construction pipeline exceeds $6bn. The most prominent project is the Bahrain International Sports City development in Sakhir. In September, 21 local and Saudi Arabian contractors were prequalified for the first-phase construction contract, which is expected to include Bahrain’s largest sports stadium and a multipurpose indoor sports arena.
The planned National Assembly Building in Manama is another significant civic project. Bids submitted earlier this year included three options from Cebarco Bahrain, ranging from $163.8m to $200.3m, alongside offers of $239.4m from Nass Contracting and $316.4m from Kooheji Contractors.
The four-storey complex will be built on a reclaimed island and will include a main hall for joint sessions, separate debating chambers, administrative offices, an auditorium, library, museum, meeting rooms, public spaces, underground parking and supporting facilities.
These projects provide a route out of Bahrain’s multi-year downturn. The market’s recovery, however, will depend on whether the government converts feasibility studies, advisory mandates and prequalification exercises into construction awards.
