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)

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.

Saudi Arabia approves new procurement law17 August 2026
Saudi Arabia’s Council of Ministers has approved a new Government Tenders and Procurement Law (GTPL), introducing changes to public procurement procedures and government contracting.
The Ministry of Finance announced the approval on 5 August.
The new law aims to strengthen governance and transparency, improve procurement planning and implementation, and promote fairness and equal opportunities in government contracting.
The changes give government entities greater flexibility in procurement while introducing new provisions that could affect contractors and suppliers, including contract variations, outstanding payments and procurement procedures.
Contract flexibility
According to a Ministry of Finance summary of the key amendments, one of the main changes allows government entities to increase existing contract items by up to 20% of the contract value. Contractor approval is required for increases exceeding 10%, while the total increase from adding new items or increasing existing items cannot exceed 20% of the contract value.
The amendments also introduce measures addressing outstanding payments to contractors. A government entity cannot make a new award when it has outstanding amounts owed to contractors for works or procurement and the required procedures have not been taken, after notification from the Ministry of Finance.
Exceptions apply where non-payment relates to ministry procedures or where the government entity has taken the required action on a claim but does not have sufficient budget allocations.
Single committee
Under the new law, the committees responsible for opening and examining bids will be merged into a single committee.
The maximum value for direct procurement will rise from SR100,000 ($26,700) to SR1m ($267,000) while government entities will be required to explain and document their use of direct procurement.
Direct procurement will also be permitted in cases involving research, development and innovation and certain contracts with professional practitioners.
The amendments reduce the minimum standstill period following a procurement award from five working days to three working days. Government entities will also be able to negotiate where the best bid exceeds the estimated cost plus the permitted contingency.
Localisation
The new framework includes provisions covering industrial localisation and knowledge transfer. The Ministry of Finance said it will issue rules for contracting for these purposes in cooperation with the Local Content and Government Procurement Authority.
A new regulation will also cover research, development and innovation, including tendering and contracting provisions for these activities.
Other changes involve contractors’ exposure to penalties. The maximum delay penalty on contracts, excluding supply contracts, will fall from 20% to 15% of contract value. The maximum penalty for non-performance in continuous-performance contracts will also fall from 20% to 15%.
The value of purchases exempt from providing a final guarantee will rise from SR100,000 ($26,700) to SR300,000 ($80,000). Additional exemptions will apply to contracts with professional practitioners and emergency or urgent cases.

GCC reviews first phase of water interconnection study17 August 2026
The GCC General Secretariat has completed the first phase of a study examining the feasibility of developing water interconnection projects between GCC member states.
A two-day workshop reviewing the study’s findings concluded on 12 August at the headquarters of the GCC Interconnection Authority (GCCIA) in Dammam, Saudi Arabia.
The GCC General Secretariat organised the workshop in cooperation with GCCIA, with representatives from relevant authorities and experts in water, infrastructure and water security taking part.
Participants reviewed the first phase findings, including an assessment of existing water supply infrastructure and the actual water needs of GCC member states. They also discussed the technical requirements and data needed to complete the study.
The study is intended to identify practical options and feasible solutions for developing a regional water interconnection network. This includes establishing an implementation roadmap.
The initiative aims to improve the GCC states’ ability to respond to emergencies and crises and support continuity of water supplies.
First meeting
The workshop followed a virtual meeting on 22 July between the GCC General Secretariat and Saudi Arabia’s water authorities as part of the study.
That meeting, which also involved consultancy Artelia, reviewed the study’s methodology and implementation stages. These include assessing existing water systems across GCC states, their resilience and emergency readiness, and developing technical options for bilateral water interconnection projects.
In Saudi Arabia, the study is focused primarily on the Eastern Province and Riyadh. It is assessing water production and desalination facilities, transmission pipelines, strategic reservoirs, pumping stations and existing and planned projects.
The study is also examining potential bilateral connections between Saudi Arabia and Bahrain, Kuwait and Qatar, as well as the possibility of a connection with the UAE.
The 22 July meeting also discussed potential connection points and routes, water flow directions and the possibility of designing interconnection pipelines to operate in both directions.

Neom’s next phase is crucial to green hydrogen pipeline17 August 2026
Commentary
Mark Dowdall
Power & water editorThe completion of construction at Neom Green Hydrogen comes at an important point for Saudi Arabia’s wider hydrogen ambitions.
The project has already shown that a large green hydrogen scheme can secure financing by reaching financial close in 2023 with long-term offtake from Air Products.
With the facility now moving into commissioning ahead of a targeted commercial operations date next year, Neom could soon give lenders and developers real evidence on the performance, costs and risks of a large-scale green hydrogen project.
That could be important for projects still moving through development. Acwa’s Yanbu Green Hydrogen Hub, for example, is targeting commercial operations in 2030.
The project has brought in Germany’s EnBW as a co-developer and minority investor and Japan’s Itochu as a co-developer, investor and offtaker. Acwa is targeting production of 2.5 million tonnes a year of green ammonia from the hub.
Saudi Arabia is also putting more of the framework around the industry in place. In July, the government granted Acwa exclusive rights to export green hydrogen produced in the kingdom along with its derivatives, including green ammonia, methanol and fuels.
However, partnerships and policy support alone will not remove the commercial questions facing projects. Yanbu still needs to progress through development and secure the financing needed to move into construction.
Neom’s financing structure and 30-year offtake may be specific to the project, but its operating performance should give future developers and lenders a clearer reference point for assessing production, reliability and costs.
While Neom will not make the next projects bankable on its own, if it stays on track and performs as expected, it could give lenders a stronger basis for assessing projects that follow. In the long-run, this could be one of its most important contributions.

Five bid for King Salman Bay construction work17 August 2026

Five teams have submitted bids for the contract covering the marine infrastructure works at King Salman Bay on the Red Sea coast, north of Jeddah.
MEED understands that the bids were submitted on 31 July.
The bidders include:
- Deme / Archirodon (Belgium/Netherlands)
- Van Oord (Netherlands)
- Abdulmohsen Altamimi / NMDC Group (local/UAE)
- Urbacon / Negida Contracting (Qatar/Egypt )
- Modern Building Leaders / China Harbour (local/China)
The scope includes dredging and earthworks, as well as quay wall and edge protection works spanning about 11 kilometres.
King Salman Bay is expected to be a waterfront development that aims to reshape the city’s northern Red Sea frontage into a mixed-use destination, anchored by public-realm improvements and leisure-led development.
Saudi gigaproject developer Red Sea Global (RSG) is developing the project.
The latest development follows RSG’s award of an estimated SR100m ($27m) contract to construct a solid waste management centre at its Red Sea Project. The scope includes four buildings: a materials recycling facility, a transfer station, an administration building and a vehicle maintenance building.
In October last year, MEED reported that RSG had secured a SR6.5bn ($1.7bn) credit facility to further develop Amaala, its luxury tourism destination on Saudi Arabia’s northwestern Red Sea coast.

PDO allows more time for Al-Ghubar field project prices17 August 2026

Petroleum Development Oman (PDO) has allowed contractors additional time to prepare commercial bids for a project to build a new facility to handle additional oil production from the Al-Ghubar field in the sultanate.
The Al-Ghubar field is located in the Ghaba Salt Basin at Qarn Alam, within majority state-owned PDO’s Block 6 concession area.
The Al-Ghubar gas-oil gravity drainage (GOGD) facility will be designed as a sour (hydrogen sulphide) facility and is expected to handle maximum oil production of 1,800 standard cubic metres a day (cm/d), a maximum total water flow rate of 10,421 standard cm/d, and maximum gas lift of 256,934 standard cm/d. Production from the planned Al-Ghubar GOGD facility will be exported to PDO’s main oil line.
Following receipt of the technical bids for the project in July, PDO granted contractors additional time – until 16 August – to submit commercial bids for the project, MEED recently reported.
The project operator has now extended the deadline for submitting commercial bids to 1 September, sources told MEED.
PDO floated the tender for the Al-Ghubar GOGD facility project in March, setting an initial bid submission deadline of 4 May, MEED previously reported.
PDO later extended the deadlines for submission of technical and commercial bids to 26 July and 7 August, respectively. Contractors submitted technical proposals by the revised deadline, according to sources.
The following contractors, among others, are understood to be bidding for the project:
- Archirodon (Greece)
- Engineering for the Petroleum & Process Industries (Egypt) / Petrojet (Egypt)
- Jereh (China)
- Kent (UAE)
- Larsen & Toubro Energy Hydrocarbon (India)
The scope of work on the Al-Ghubar GOGD facility project covers the engineering, procurement and construction (EPC) of the following:
- On-plot scope consists of:
- Production separator
- Test separator
- Concentric wash tank
- Wet oil pump
- Water bath heater
- Surge tank
- Gas injection/gas lift compressor (centrifugal)
- Utilities (Instrument Air compressors, chemical injection skids, drain system, vent system)
- Suction scrubber
- Air coolers
- Discharge scrubbers
- Condensate flash drum
- Atmospheric pressure knock-out drum
- Flare system
- Gas heater
- Water disposal pump
- Oil shipping pump
- New 132kV substation and plant substation (housing 6.6kV & 415-Volt switchboard)
- New control room
- Off-plot scope consists of:
- Off-plot pipeline network (bulk header, test header, gathering infrastructure/ gathering line header, instrument air header, water disposal header)
- Two remote manifold stations
- Tie-in connection to main oil line
- Tie-in to gas network pipeline
PDO previously intended to tender the Al-Ghubar GOGD project under its framework structure with selected EPC contractors, but eventually tendered it separately.
PDO is the operator of the Block 6 hydrocarbons concession in Oman, which is the sultanate’s largest and most prolific concession. Situated onshore and covering an area of 75,119 square kilometres, Block 6 contains 202 oil fields and 43 gas fields, with PDO producing a total of approximately 680,000 barrels a day (b/d) of oil and condensates from those fields.
The Omani government holds a 60% stake in PDO through Energy Development Oman (EDO). The other shareholders are UK-based Shell (34%), France’s TotalEnergies (4%) and Thailand’s state-owned PTTEP (2%).
