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)
  • Daewoo Engineering & Construction (South Korea)

EPC companies that have been prequalified for package J3 are:

  • Acciona Construccion (Spain) – Dubai branch
  • Alghanim International General Trading & Contracting (Kuwait) 
  • China Railway Group (China)
  • China State Construction Engineering Corporation (China)
  • Daewoo Engineering & Construction (South Korea)
  • DETech Contracting
  • Archirodon Construction (Overseas) Company (Greece) / BESSAC (France)
  • China Civil Engineering Construction Corporation (China) – Dubai branch / Shanghai Tunnel Engineering Company (STEC) / China Railway 14th Bureau Group Corporation 
  • Gulermak Agir Sanayi Insaat (Turkiye) / DETech Contracting (local) 
  • International Foundation Group (IFG, local) / General Construction Company (local)

  • The Petroleum Projects & Technical Consultation Company – Petrojet (Egypt)

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.

  • EtihadWE tenders $150m Ajman substation project

    21 July 2026

    The UAE’s Etihad Water & Electricity (EtihadWE) has tendered a contract to build three new substations in Ajman.

    Estimated to cost $150m, the project involves the construction of three new 132/11kV substations in the Bahya, Rumaila and Liwara districts. It also includes associated 132kV underground cabling works to connect the substations to the existing transmission network.

    The bid submission deadline is 10 August.

    According to tender documents, the project will add distribution capacity to support load growth and improve the security of electricity supply in the emirate.

    The scope of work includes site preparation, construction of three substation buildings and foundations, installation of 132kV GIS/AIS switchgear, 132/11kV power transformers and 11kV switchgear, as well as protection, control, Scada and telecommunications systems.

    Etihad WE is responsible for electricity and water services in Ajman, Umm Al-Quwain, Ras Al-Khaimah, Fujairah and parts of Sharjah. The utility has been investing in new substations and transmission infrastructure as electricity demand continues to increase across the Northern Emirates.

    This includes a 132/33/11kV substation project on Al-Marjan Island in Ras Al-Khaimah. Construction work is ongoing on the project, with Maetal Dubai serving as the main contractor.

    EtihadWE is also finalising a new masterplan that will cover network capacity requirements and expansion priorities for the next 10 to 15 years.

    In June, Abdulla Al-Khemeiri, chief operations officer, told MEED: “We are currently reviewing it, and we need to obtain shareholder approval first. Once it is approved, it will be released, hopefully by the end of the year.”

  • Seven seeks contractors for Dammam water park and hotel

    21 July 2026

     

    Saudi Entertainment Ventures (Seven), a wholly owned subsidiary of the Public Investment Fund, is preparing to shortlist general contractors for the main construction package of its Dammam Water Park & Hotel project in the Al-Hamra district.

    The waterfront development sits on a 324,300-square-metre (sq m) plot.

    A notice was issued to contractors in July, and the client is expected to finalise the shortlist by the end of this month.

    Seven is seeking firms capable of delivering a lump-sum, turnkey solution for both the water park and a 321-key lifestyle hotel. Construction is expected to take 24 months from contract award.

    The water park is designed around five themed zones and will feature what is billed as the world’s first double-tornado/triple-wave waterslide.

    The park will include 21 major rides and attractions, 21 food and beverage outlets, 66 cabanas, parking for 1,100 vehicles and a daily peak capacity of 4,500 guests.

    Slide procurement has already been completed directly by Seven. The selected contractor will be responsible for locally sourcing slide towers, integrating them with rockwork and secondary steel, and installing the units.

    Detailed design and issued-for-construction packages are complete.

    Marine works, piling, dewatering and site utilities are being progressed separately by the existing early works contractor.

    The hotel component covers roughly 31,700 sq m of gross floor area and will offer 321 guest rooms, four F&B outlets, spa and wellness facilities, a family pool, and meeting, incentive, conference and exhibition space.

    The new contractor’s scope includes superstructure concrete works, façade and roof works, mechanical, electrical and plumbing, interior fit-out and landscaping.

    Seven will consider only contractors with demonstrated experience delivering water parks with complex aquatics, theming and rockwork – either directly or through clearly defined subcontractor partnerships – along with a track record in high-end turnkey hotel fit-outs.

    Construction of Seven’s Dammam entertainment complex is currently under way. In October 2023, Saudi Binladin Group won contracts worth around SR5bn ($1.3bn) from Seven to build two entertainment destinations in the Dammam and Al-Khobar areas of the Kingdom’s Eastern Province.

    The Al-Khobar entertainment complex is being built on reclaimed waterfront land. The complex spans around 300,000 sq m and is also known as ‘The Waves’.

    The Dammam entertainment complex spans 360,000 sq m and is being built on reclaimed land on the Dammam waterfront.

  • Contractors await decision on Riyadh airport sewage plant

    21 July 2026

     

    Seven contractors are awaiting a decision on a contract to build a sewage treatment plant at the King Salman International airport (KSIA) development in Riyadh, according to sources.

    It is understood that bids were submitted to King Salman International Airport Development Company (KSIADC) in March, following the tender’s release earlier this year.

    The plant will treat wastewater generated by the airport and surrounding developments, including passenger terminals, runways, residential districts, commercial facilities and logistics areas.

    The facility will have a treatment capacity of 92,000 cubic metres a day. The contract is estimated to be worth SR700m ($187m).

    The bidders (all local) are:

    • Al-Rawaf Trading & Contracting
    • Almajal Alarabi
    • Nesma Water & Energy
    • Safari Company
    • Saudi Services for Electro-Mechanic Works
    • Washnah Contracting
    • Water & Environment Technologies (Wetico)

    The project scope includes the construction of the treatment plant, the installation of preliminary, secondary and tertiary treatment systems, sewage collection and conveyance pipelines, pumping stations, and electrical and control systems.

    US-headquartered Jacobs is acting as the main project consultant. Commercial operations for the plant are scheduled for 2029.

    The sewage treatment plant is one of several water infrastructure packages planned for the airport. KSIADC is also evaluating bids for a separate $30m engineering, procurement and construction contract covering potable water and fire water tanks and an associated pumping station. The same seven companies have submitted bids for that package.

    Earlier in July, MEED exclusively reported that a joint venture of Beijing-headquartered China Civil Engineering Construction Corporation and Dammam-based Mofarreh AlHarbi & Partners had won a deal to undertake the enabling and substructure works for Terminal 6 at KSIA.

    The latest development followed KSIADC’s receipt of prequalification statements from contractors on 1 July for two new packages at KSIA.

    These include the construction of a permanent East-West corridor and landside access roads serving the North and South terminals.

  • Dubai Municipality awards Tasreef drainage contract

    21 July 2026

     

    Dubai Municipality has awarded local firm Detech Contracting the engineering, procurement and construction (EPC) contract for the TF-15-C1 package of its Tasreef Rainwater Drainage Network programme.

    It is understood the municipality issued the letter of award for the contract earlier this month, covering the construction of a stormwater drainage system along Al-Wasl Road and communities west of the Dubai Canal.

    The project includes the construction of a gravity-based stormwater pipeline network with diameters of up to 3.5 metres. It is estimated to cost $100m.

    It was tendered in February through the government’s Sewerage and Recycled Water Projects Department, with bids submitted in April.

    The package forms part of the wider Tasreef initiative, which is intended to improve Dubai’s flood resilience.

    The TF-15-C2 package was recently awarded to China State Construction Engineering Corporation for a stormwater drainage network project located along Umm Suqeim Road in the Al-Barsha and Al-Quoz areas of Dubai.

    The project is estimated to cost $162m and includes the construction of about 20 kilometres of new stormwater pipelines. Similar to the C1 package, it is located west of the Dubai Canal and will connect the Al-Quoz 3 and Al-Quoz 4 industrial areas with Al-Quoz 1.

    Separately, Al-Kharafi has won a drainage EPC contract (Ds207) to upgrade an existing pumping station for the municipality, a source said. The package focuses mainly on mechanical works and is valued at about $39m.

    In May, MEED reported that local firm Nael Construction & Contracting had signed a contract with Dubai Municipality to build a sewage and stormwater drainage system in Dubailand.

    The project (DS-204-C1) involves the construction of a drainage system with sewage gravity pipelines of up to 2,200mm in diameter.
