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.

Lowest bidder emerges for Kuwait Airport Terminal 2 operations19 October 2026

Ireland’s DAA International has emerged as the lowest bidder for the contract to operate, manage and maintain the new passenger Terminal 2 (T2) at Kuwait International airport, submitting an offer of KD419m ($1.35bn).
Official price-opening records released by Kuwait’s Central Agency for Public Tenders on behalf of the Directorate General of Civil Aviation show three international airport operators submitted commercial bids for the tender.
DAA International’s proposal undercut its nearest rival by about 45%. Turkiye’s TAV Airports Holding submitted the second-lowest offer at KD764.15m ($2.46bn), while South Korea’s Incheon International Airport Corporation bid KD959.48m ($3.1bn).
All three proposals were marked as approved in the tender committee’s price disclosure.
The contract entails the operation, management and improvement of training, maintenance and development services across Terminal 2 and its associated aircraft parking aprons.
The remit also includes corporate management of centralised operation and maintenance across the broader Kuwait International airport model, centralising operational procedures, systems integration and service delivery across the aviation hub.
Technical documents indicate the winning operator will oversee facility management, terminal operational readiness, passenger processing systems, apron operations and staff development programmes before and after the complex’s commercial launch.
MEED reported in June 2023 that six airport operators had initially been invited to bid for the Terminal 2 operating concession.
Terminal 2 is the centrepiece of Kuwait International airport’s multibillion-dollar expansion, aimed at boosting total handling capacity to 25 million passengers a year.
Turkish contractor Limak Insaat is executing the main terminal building under an estimated $4.34bn contract awarded in 2016.

Dubai tenders Al-Maktoum-Dubai South drainage scheme19 October 2026
Dubai Municipality has invited contractors to submit bids by 5 November for the construction of a stormwater drainage system connecting Al-Maktoum Airport and Dubai South
The project, designated TF-06-C2, involves approximately 20 kilometres of pipelines with diameters ranging from 400mm to 3,000mm. The works will use deep trenchless construction and conventional open-cut methods.
The scheme is one of four projects, for which a project management consultancy (PMC) tender was issued earlier this month.
The tender for TF-06-S1 Supervision of Stormwater Drainage System Projects – Package 4 was issued on 6 October.
The consultancy covers the following projects:
- TF-06-C1: Construction of a stormwater pond connecting Al-Maktoum Airport and Dubai South
- TF-06-C2: Construction of a stormwater drainage system connecting Al-Maktoum Airport and Dubai South
- TF-07-C1: Construction of a stormwater drainage system on Sheikh Zayed Bin Hamdan Road connecting developers
- TF-24-C1: Connecting developers’ areas to the stormwater networks in Dubailand
The projects are part of Dubai Municipality’s wider Tasreef programme, intended to increase Dubai’s rainwater drainage capacity by 700% by 2033 and provide capacity for the emirate’s needs for the next 100 years.
Investment in the UAE water sector has been dominated by stormwater drainage and network resilience schemes this year, as Dubai Municipality advances procurement under its AED30bn ($8.1bn) Tasreef programme.
TF-07-C1
As previously reported, contractors are preparing to submit bids on 22 October for the main construction contract for TF-07-C1.
The project covers more than 100 million square metres between Sheikh Mohammed Bin Zayed Road and Emirates Road, and from Expo Road to Dubailand.
It will provide stormwater infrastructure and service connections for more than 20 private developers and Al-Yalayis 5, as well as supporting major roads in the Jebel Ali area. The construction scope includes a major gravity drainage system with pipeline diameters of up to 3,000mm.
TF-24-C1
Bids for TF-24-C1 were submitted on 1 October, with Nael Construction & Contracting, Al-Nasr Contracting Company and Al-Kharafi & Sons understood to be among the bidders.
The project will connect developers’ areas in Dubailand to the stormwater network. It includes 18km of stormwater drainage pipelines with diameters of up to 1,800mm and 3.5km of gravity sewer pipelines with diameters of up to 1,000mm.
As MEED understands, the main contract tender for TF-06-C1 has yet to be released.

Contractor wins $44m Morocco rail stations deal19 October 2026
Morocco’s national railway operator, Office National des Chemins de Fer (ONCF), has awarded a MD437.6m ($44.5m) contract to local firm Jet Contractors to build five railway stations along the Benguerir-Marrakech corridor.
The project forms part of the wider Kenitra-Marrakech high-speed rail development programme.
Jet Contractors will build one high-speed rail station and four regional express rail stations.
These include two stations in Benguerir, and one each at Sidi Bou Othmane, Sidi Ghanem and Marrakech Stadium.
The scope of work includes construction and fit-out of the stations and associated infrastructure, including concrete structures, platforms, ancillary facilities, passageways, circulation areas and connection zones within the stations.
It also covers architectural finishing works; testing and commissioning of electrical networks; and all mechanical, electrical and plumbing services.
The contractor will also provide all safety, security and protection systems, including alarms, fire detection and firefighting systems, and surveillance systems.
Morocco awarded multiple civil works contracts in 2024 to international and local firms to build its Kenitra-Marrakech high-speed railway line.
The rail project is part of a $37bn strategy to connect more of Morocco’s cities, ports and airports by rail. It will stretch 375 kilometres from Kenitra on the northwest coast to Marrakech in the south.
The project is divided into seven lots, each measuring 36km to 64km. The rail link will pass through cities including Rabat, Sale and Casablanca.
The link will extend the Al-Boraq high-speed rail line between Tangier, Rabat and Casablanca. The line began operating in 2018 and was Africa’s first high-speed railway system.

Firms submit Dubai multibillion-dollar road scheme interest19 October 2026

Register for MEED’s 14-day trial access
Contractors submitted expressions of interest on 10 October for a design-and-build contract for a multibillion-dollar new road that will run parallel to Sheikh Zayed Road.
Dubai’s Roads & Transport Authority (RTA) held an online meeting after the submissions to prepare for the prequalification phase of tendering, expected to start in a few weeks.
The scope covers about 30 kilometres (km) of works.
These include about 15km of viaduct along First Al-Khail Street and more than 14.5km of bridge ramps, along with other associated infrastructure works.
The RTA floated the expression of interest notice to contractors in early September.
The project is another significant initiative aimed at alleviating pressure on the existing Sheikh Zayed Road section from Hadiqa Street to Hessa Street.
Dubai has previously explored bold concepts to expand capacity on Sheikh Zayed Road, including proposals to introduce double-decker sections to add extra lanes without widening the existing corridor.
The idea was discussed in the context of rising congestion and limited right-of-way along one of the city’s busiest arterial roads, with elevated decks potentially carrying through traffic while existing at-grade lanes served local access.
The plans ultimately became standalone schemes, with subsequent efforts focusing instead on corridor-wide upgrades, interchange improvements and complementary public transport expansions to manage demand more sustainably.
The latest project aligns with Dubai’s continued investment in upgrading and expanding its road network to keep pace with rapid population growth and rising commuting demand.
Planning for growth
Dubai launched the 2040 Urban Master Plan in March 2021, referencing studies indicating that the emirate’s population will reach 5.8 million by 2040, up from 3.3 million in 2020. The daytime population is set to increase from 4.5 million in 2020 to 7.8 million in 2040.
In December 2022, Sheikh Mohammed Bin Rashid Al-Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, approved the 20-Minute City Policy as part of the second phase of the Dubai 2040 Urban Master Plan.
In addition to the road projects, the RTA’s Dubai Metro Blue Line extension and Dubai Metro Gold Line form part of Dubai’s plans to improve residents’ quality of life by cutting journey times, as outlined in the policy.
The policy aims for residents to have 80% of their daily requirements within a 20-minute journey, on foot or by bicycle. This goal will be achieved by developing integrated service centres with all necessary facilities and increasing population density around mass transit stations.

Libya seeks offshore contractors for $8bn gas project19 October 2026
Libya’s Mellitah Oil & Gas Company (MOG) has invited companies to prequalify for a major offshore package as part of its Mellitah Complex Expansion & CO2 Management Integrated Development Project, which is estimated to be worth about $8bn.
The package is estimated at around $3bn and focuses on developing offshore pipelines and subsea systems for the “E” Offshore Installation Project and CO2 project.
The deadline to submit prequalification documents is 5 November. The contract will use the engineering, procurement, installation and commissioning (EPIC) model.
MOG is a joint venture of Libya’s National Oil Corporation and Italian oil and gas company Eni.
This is not the first time MOG has invited submissions for the offshore pipelines and subsea systems package. The company originally launched a prequalification process for the EPIC contract in 2021, but the project experienced delays and the process was eventually cancelled. The prequalification process was restarted nearly three years later, but it was also ultimately abandoned.
Complex expansion
As part of the Mellitah Complex Expansion & CO2 Management Integrated Development Project, two offshore structures – Structure A and Structure E – will be developed in Libya’s offshore block NC 41.
Structure A is in the central-western part of the area, about 80 kilometres (km) from the Libyan coast, with a water depth of 95-105 metres.
Structure E is located in the central-eastern part of the area, about 130km from the Libyan coast, in a water depth of 205-235 metres.
The scope of the wider project includes:
- A new wellhead platform installed in 96 metres of water as part of the development of Structure A
- A new production platform installed in about 220 metres of water depth as part of the development of Structure E
- Modification of the existing Sabratha platform
- Sealines and subsea systems for structures A and E
- Upgrading the existing onshore Mellitah complex
Project contract awards
In June 2024, MOG awarded an offshore engineering, procurement and construction (EPC) contract worth €1.2bn ($1.28bn), which was part of the Mellitah Complex Expansion & CO2 Management Integrated Development Project.
The contract was awarded to a consortium of three Italian companies: Rosetti Marino, Kerry Project Logistics and Gruppo Antonini.
In a statement, Rosetti Marino said its share of the project contract was worth €400m ($428m), comprising 33% of the total contract value.
Rosetti Marino said its scope of work includes EPC and load-out activities to deliver the topside of the approximately 6,000-tonne gas production wellhead platform, named WHP-A, to be installed off the coast of Libya.
Project setbacks
During 2023 and 2024, several setbacks affected the Mellitah Complex Expansion & CO2 Management Integrated Development Project.
In November 2023, MOG restarted the prequalification process for an upstream offshore package worth an estimated $700m.
The project scope involves modifications to the offshore Sabratha platform at the Bahr Essalam field.
Less than two months later, MOG restarted prequalification for a second package as part of the integrated development project.
The scope of the second package covers key sealine and subsea systems.
No reason was given for restarting the prequalification process for two of the project’s packages.
