The region’s most ambitious causeway projects

8 February 2023

 

The submission of feedback questionnaires and meetings with contractors for the planned second causeway connecting Saudi Arabia and Bahrain is the latest sign of potential progress on one of the region’s largest infrastructure projects.

Causeways have a chequered history in the region. The first causeway connecting Saudi Arabia and Bahrain was completed during the 1980s, and since then, it has had a transformative impact on the Bahraini economy. 

The project’s success has inspired other causeways. But while these schemes remain ambitions for many in the region, construction progress has been limited. The hope is that a successful second causeway linking Saudi Arabia and Bahrain will foster the delivery of other longstanding causeway plans.

These are the most ambitious causeway schemes that the region has planned:

 Second Saudi Arabia-Bahrain causeway

The second causeway between Saudi Arabia and Bahrain is the most likely to proceed. Planned by the King Fahd Causeway Authority, the $3.5bn project, which has been called the King Hamad Causeway project, is moving towards construction.

In 2021, senior government officials in Bahrain told MEED that the project was progressing towards tendering as financial studies had been completed.

The project was included in Bahrain’s $30bn Strategic Projects Plan that was announced later in 2021. As well as the causeway, the plan includes building new urban areas on five reclaimed islands to increase the country’s total land area by 60 per cent. It also comprises plans for a new airport.

The second causeway involves building a 25-kilometre road and rail crossing linking Saudi Arabia and Bahrain. It will follow the same alignment as the existing King Fahd Causeway.

It has been earmarked for delivery on a public-private partnership (PPP) basis. The King Fahd Causeway Authority appointed a consortium to provide transaction advisory services in late 2019.

The $8.9m consultancy agreement was signed with a consortium of Netherlands-headquartered KPMG, US-based Aecom and UK-based CMS. The team was tasked with working on developing the financing model, the required engineering specifications and design, as well as helping with the assessment and selection of the project’s developers.

Canada-based SNC Lavalin and UK-based consultancy firm PwC conducted the project due diligence study in 2017.

The existing King Fahd Causeway is operating at capacity. About 11.5 million cars cross the causeway every year, and the growth has been 6 per cent per annum over the past 10 years.

 Qatar-Bahrain causeway

There have also been suggestions that the proposed causeway bridging Bahrain and Qatar may be revived. In March 2022, Manama called for work to restart on the causeway joining the two countries.

“We in the Kingdom of Bahrain renew the call for the start of bilateral talks between the two sides in accordance with the mechanisms agreed upon in the Al-Ula statement,” said Bahrain’s undersecretary for land transportation and post in an official statement published by the official Bahrain News Agency.

The estimated $4bn Qatar-Bahrain causeway project was put on hold and the contracting consortium demobilised in 2010.

A joint venture of state-owned developer Qatari Diar Real Estate Investment Company and French contractor Vinci Construction Grand Projets led the consortium. The other consortium members were Germany’s Hochtief, Athens-based Consolidated Contractors Company (CCC), Dredging International from Belgium and the local Middle East Dredging Company (Medco).

The planned 40km bridge includes a four-lane motor crossing scheduled for completion in 2013 and two railway lines forming part of the GCC rail network.

The project also comprises 22km of bridges and viaducts, 18km of embankments and two 400-metre cable-stayed bridges. The causeway connects Ras Ashairij on the west coast of Qatar to Askar on the east coast of Bahrain.

The project was also known as the Friendship Bridge and was to be jointly funded by the Qatari and Bahraini governments, which intended to recover some of the construction costs by implementing a toll system on the bridge.

The crossing would cut the journey time between the two countries, which currently involves a detour through Saudi Arabia, from five hours to just 30 minutes.

 Saudi Arabia-Egypt causeway

The prospects for the causeway connecting the $500bn Neom project in Saudi Arabia and Egypt’s Sinai Peninsula across the Straits of Tiran improved last year after US President Joe Biden’s visit to Saudi Arabia.

After the visit, a joint communique issued by Washington and Riyadh referred to the development of Tiran Island.

“President Biden welcomed the arrangements by Saudi Arabia to remove the Multinational Force & Observers (MFO) from the Island of Tiran, including the removal of US troops there as part of the MFO mission, while preserving and continuing all existing commitments and procedures in the area,” it said. 

“This area of the Red Sea will now be developed for tourism and economic purposes, contributing to a more secure, peaceful and prosperous region.” 

The US-Egyptian-Israeli-backed MFO was founded in 1981 to oversee the terms of the 1978 Camp David Accords, which included the full Israeli withdrawal from the Sinai Peninsula.

In 2016, Egypt and Saudi Arabia agreed during a state visit to Cairo by King Salman bin Abdulaziz al-Saud to develop a causeway linking the two countries across the Red Sea. 

The agreement was made as part of a broader deal that would also involve Egypt ceding the sovereignty of the two Tiran islands to Saudi Arabia.

While details of the proposed crossing were never revealed at the time, it was understood to be a revival of a $4bn project announced in 2011. That scheme involved building a 32km crossing stretching over the Straits of Tiran from Ras Humaid in Tabuk, in the northern region of Saudi Arabia, to Ras Nasrani, close to the Egyptian resort of Sharm el-Sheikh.

Plans to link Saudi Arabia and Egypt are far from new. The development of a causeway was first mooted as far back as 1988. However, the idea has received additional focus in recent years following the launch of the Neom development in northwestern Saudi Arabia, which includes Ras Humaid. Part of the Neom scheme, the 170km-long linear city known as The Line, will extend from the promontory inland to the city of Tabuk.

UK-based Arup was reported to have been selected in 2019 for the next stage of the feasibility study for the causeway. 

Saudi Arabia was understood to be considering using a public-private partnership (PPP) model for the scheme, similar to other transport projects planned in and around the kingdom.

 Yemen-Djibouti causeway

A 28.5km causeway was planned to connect Yemen and Djibouti before the scheme was put on hold in 2010 until the governments of both countries signed the framework agreement for the project. The civil war in Yemen means it is unlikely the scheme will make any progress soon.

The estimated $20bn first phase involved building the link between the Yemeni mainland to the island of Perim in the Red Sea. Phase two would have then connected Perim with Djibouti.

The wider project also involves building two cities at each end of the link. The total investment required to construct the cities and the bridge is $200bn.

Dubai-based Al-Noor Holding Investment Company was developing the project.

In 2009, the company said it expected to award a build-operate-transfer contract for the first phase of the bridge and that three companies had expressed interest in funding and building the road and rail link. Denmark’s Cowi prepared the preliminary design for the crossing.

 UAE-Qatar causeway

In 2005, Abu Dhabi and Doha were reported to have been setting up a joint company to oversee the implementation of the proposed UAE/Qatar causeway.

The 40km causeway was expected to start near Sila in Abu Dhabi emirate and extend to the south of Doha.

The estimated $13bn crossing would have significantly cut journey times. At present, traffic between Qatar and the UAE has to pass through 125km of Saudi Arabian territory.

The scheme stalled shortly afterwards. Problems included difficulties with the route, which ran through Saudi Arabian territorial waters.

  • Managing risk in the GCC construction market

    19 December 2025

     

    The scale and complexity of construction projects under way in the GCC region has attracted global attention. And while large-scale project announcements continue to dominate the headlines, the underlying risks – insufficient financing, harsh contract clauses and a tendency to delay dispute resolution – are often overlooked.

    Around the region, many contractors are experiencing difficulties once projects have started because they mistakenly believe they have the necessary in-house skillsets to navigate these complex issues.

    MEED has convened a panel of construction consultants and specialists to develop a checklist to help contractors and subcontractors operating in the region to navigate the market’s challenges as the sector moves into 2026.

    The proactive steps are aimed at positioning a company so that it can maximise recovery and mitigate threats posed by unresolved claims and poor commercial or contractual administration.

    Systemic risk

    The regional market is characterised by several systemic issues that amplify risks for contractors. 

    The fundamental problem is finance. Projects frequently suffer because they are not fully financed from the start, which places financial strain on contractors. This problem is then compounded by the region’s traditional contractual environment, which means disputes are typically not finalised until well after jobs have been completed, creating cash flow problems for contractors, particularly near the end of such projects.

    Further financial strain is created by unconditional performance guarantees and retention. The combined requirement for advance payment bonds, a 10% performance bond and sometimes 5%-10% retention represents a significant draw on contractors’ cash flow. The growing tendency of employers to pull bonds further exacerbates the situation.

    Many contractors sign up to one-sided contracts so as to secure more work, rather than challenging their employers. Key contractual issues include:

    > Unrealistic timelines: Contractors set themselves up to fail by accepting unrealistic timescales on projects, despite the knowledge that the work often takes twice as long.

    > Deficient design: A major risk, particularly on high-profile projects, is a lack of specification and design progress. Many contracts, such as the heavily modified Silver Book – a standard contract published by the International Federation of Consulting Engineers (Fidic) for turnkey engineering, procurement and construction projects – presuppose that the contractor has sufficient information to design, build and deliver, even when there is substantive information missing, which renders lump-sum pricing obsolete and inevitably leads to dispute.

    > Lowest-bid mentality: Contractors often fail to factor necessary commercial support from legal and claims specialists into their tender figures, making their bid appear more competitive but leaving them without a budget to seek help until it is too late. As a result, projects are managed with budgets that are barely sufficient, rather than being run properly to a successful conclusion.

    Supply-chain erosion

    The quality and capacity of the subcontractor market, particularly in the mechanical, electrical and plumbing (MEP) field, has eroded significantly. 

    Some major MEP players have closed or left the market due to underpricing, prompting contractors to call in their performance bonds. This means the region is receiving progressively lower quality for increasingly higher costs, further straining the delivery phase for main contractors.

    The risk of subcontractor insolvency is increasing and must now be considered a primary project risk. Contractors should monitor financial health, diversify subcontractor dependencies, challenge allocated resources and secure step-in rights wherever possible.

    Many Silver Book contracts in the GCC now include heavily amended, employer-friendly clauses that push design and ground-risk even further onto the contractor – often beyond what Fidic intended. These amendments require careful review and firm pushback.

    The GCC remains a market of opportunity, but success in 2026 will belong to contractors that combine disciplined tendering, transparent commercial governance and early issue resolution. Optimism is not a strategy; preparation is. 

    A 10-point checklist for contractors in 2026

    1. Mandate contractual due diligence: Invest time and money into a thorough contract review before signing. Be prepared to challenge harsh clauses, particularly those unfairly allocating risk, such as unknown conditions and full design responsibility. Assume that bespoke rather than standard amendments govern your entitlement. Treat the special conditions as the real contract.

    2. Factor commercial support into the budget: Do not omit the cost of essential commercial support from the tender, such as quantity surveyor teams, quantum and delay specialists, legal review and claims preparation. Even if not visible in the front-line figures, this cost – which could be as low as 0.01% of the project value – must be factored in to ensure a budget for early and continuous engagement.

    3. Prepare a realistic baseline programme: Stop committing to programmes just to fit the tender. Develop a realistic programme from the start, identifying risks and including necessary code books to track delays early. Consider commissioning an independent programme review at the tender stage – this is common internationally and reduces later arguments about logic, durations and sequencing.

    4. Confirm project funding: Ensure that the project financing is fully in position before starting work. Many problems stem from projects that are only partially financed, leading to cash running out near completion. Gone are the days of not asking employers for greater transparency when it comes to funding projects.

    5. Establish a strong commercial and claims function: This is where commercial management starts. Set up systems to ensure contractual compliance, including seven-day claim notifications. Variations are inevitable, and proper substantiation is required to secure entitlement – if it is not recorded, it cannot be recovered. Diaries, cost records and notice logs remain the foundation of entitlement.

    6. Seek early specialist engagement: Prevention is better than a cure. Bring in specialists early to examine time and cost issues before problems arise. Consultants can provide advice, help set up the correct commercial systems and prevent the escalation of unresolved issues.

    7. Adopt an old-school approach to claims management: Technology is useful, but nothing beats resolving issues face to face. Engage directly with the employer’s team regularly to negotiate and agree claims early. This manages the client’s expectations when it comes to budgeting and allows the contractor to secure cash flow sooner. A simple early-warning culture – even when not contractually required – prevents surprises and builds trust with the client.

    8. Avoid wasting resources: Focus claims efforts only on events that are actually recoverable and demonstrably critical. Contractors often waste time chasing things that will not be recoverable. Prioritise issues that are both time-critical and clearly fall under the employer’s risk – everything else should be logged but not pursued aggressively.

    9. Upskill internal teams: Use specialist involvement as an opportunity to upskill your in-house commercial team. Have them sit alongside specialist consultants to learn proper commercial and contractual administration processes, creating a lasting work-culture benefit.
    10. Push for faster dispute resolution: When a dispute arises, advocate for a swift resolution mechanism like adjudication, mediation or expert determination to temporarily resolve cash flow issues. Dispute adjudication boards are intended to give quick, interim decisions. However, if not set up from the start of the project, the process becomes protracted – sometimes taking many months – so fails to provide the cash-flow relief contractors urgently need.  Where clients resist adjudication, propose interim binding mediation or expert determinations, or failing this, milestone-based dispute workshops – anything that accelerates getting cash back on site.

  • Diriyah signs land lease deal with King Saud University

    19 December 2025

    Saudi Arabia gigaproject developer, Diriyah Company, has signed a long-term land lease agreement with Riyadh Valley Company, an investment arm of King Saud University.

    Diriyah Company will lease 552,000 square metres (sq m) of land from King Saud University for a period of 70 years. 

    The deal will enable the company to add the land bank to its second phase of the Diriyah Project, which is also known as DG2.

    The agreement was signed by Diriyah Company's Group CEO, Jerry Inzerillo, and the acting president of King Saud University and Riyadh Valley Company chairman, Ali Masmali.

    Diriyah Company is already developing the area adjacent to King Saud University. In April, it awarded an estimated SR4bn ($1.1bn) contract for a utilities relocation package for the King Saud University project located in the second phase of the Diriyah Gate development (DG2).

    The contract was awarded to the joint venture of Beijing-headquartered China Railway Construction Corporation and China Railway Construction Group Central Plain Construction Company.

    The scope of the contract covers the design, construction and relocation of KSU's utilities and administration offices, as well as the construction of a district cooling plant, water storage facilities, a sewage treatment plant, a natural gas plant, a diesel transfer pumping station, a utility tunnel, irrigation water storage tanks, office buildings, warehouses and maintenance workshops.

    In addition to KSU, DG2 will feature residential developments, hotels, an opera house, the Saudi Museum of Contemporary Art, six academies, an arena and a mosque.

    The Diriyah masterplan envisages the city as a cultural and lifestyle tourism destination. Located northwest of Riyadh’s city centre, it will cover 14 square kilometres and combine 300 years of history, culture and heritage with hospitality facilities.

  • Kuwait to sign Mubarak port agreement next week

    19 December 2025

    Kuwait and China are expected to sign the agreement to develop the subsequent phases of Kuwait’s Grand Mubarak Port next week.

    According to media reports, the announcement was made by Kuwait’s Public Works Minister ​Noura Al-Mashaan on Thursday.

    The contract value is estimated to be about KD1.2bn ($4bn).

    In May, Beijing-headquartered China Harbour Engineering Company, a subsidiary of China Communications Construction Company (CCCC), signed an early contractor involvement (ECI) agreement with Kuwait to develop the next phases of the project.

    The initial works include surveying, investigation, hydrological observation, geophysical exploration, testing, model testing, process simulation, design review, owner inspection, preliminary design of sand-retaining embankments, and on-site services and management.

    The project launch ceremony was held in mid-April. It was attended by several high-profile representatives from Kuwait and China, including Fu Xuyin, China’s vice-minister of the Ministry of Transport, Zhang Jianwei, the Chinese ambassador to Kuwait, and Nora Mohammad Al-Mashaan, Kuwait’s minister of public works.

    In January, MEED reported that Kuwait’s cabinet had approved a bid from China Communications Construction Company to implement all stages of its Mubarak Al-Kabeer Port project.

    The country ramped up its efforts on the project after meetings between Kuwaiti and Chinese officials in June last year.

    In 2023, the two countries signed a memorandum of understanding to develop port infrastructure.

    Phase one of the project cost $1.2bn and was completed in 2014.

    The project’s first phase included site levelling and the development of a marina, quay walls, berths, a navigational terminal and port buildings.

    The port is not operational because the phase one works did not include vital equipment such as cranes.

    It is understood that the completion of phase two will allow the port to start operations.

    The full scope for phase two of the project is expected to include:

    • Construction of loading and unloading facilities
    • Construction of quay walls and reclamation
    • Construction of the container yard and the back of the port
    • Infrastructure works
    • Construction of buildings
    • Construction of a container terminal
    • Construction of associated facilities
    • Installation of safety and security systems

    A third phase is also planned to further expand the port.

    The latest developments follow a series of agreements signed in September 2023 to deliver some of Kuwait’s immediate development goals for 2024-28. These agreements will position Chinese companies to play a leading role in the Fourth Kuwait Master Plan 2040.

  • Metito consortium wins Mecca sewage scheme

    19 December 2025

    A team comprising Metito (UAE), Etihad Water & Electricity Company (UAE) and SkyBridge Company (UK) has been awarded a contract to develop the Hadda independent sewage treatment plant (ISTP) project in Mecca Province, Saudi Arabia.

    The contract was awarded by Saudi Water Partnership Company (SWPC), the kingdom’s principal off-taker for water and wastewater public-private partnership (PPP) projects.

    The project will be developed on a build-own-operate-transfer basis and is expected to begin operations in 2028, followed by a 25-year operating term.

    The plant will provide an initial treatment capacity of 100,000 cubic metres a day and will feature a treated sewage effluent (TSE) reuse system with a storage tank and a 38-kilometre pipeline designed to handle 350,000 cubic metres a day.

    Earlier in December, MEED reported that the team had been named preferred bidder at a levelised tariff of SR2.354 ($0.63) a cubic metre.

    SWPC selected the Miahona-led consortium as the reserve bidder for this project with the second-lowest submitted bid of SR2.599($0.69) a cubic metre.

    According to SWPC, the TSE reuse system accounted for 31% of the preferred tariff for the Arana ISTP and 27% for the Hadda ISTP.

    In March last year, SWPC signed a 25-year water-purchase agreement with a team comprising the local Miahona Company and Belgium-based Besix for the contract to develop and operate the Al-Haer ISTP in Riyadh, as part of the third batch of the kingdom’s ISTP programme.

    Four months later, the Saudi-listed Power & Water Utility Company for Jubail & Yanbu (Marafiq) joined the developer consortium.

    The Miahona/Besix team offered to develop the project for SR1.9407 ($0.5173) a cubic metre, while the second-lowest bid, from a team comprising Spain’s Acciona and the local Tawzea, was SR2.2041($0.588) a cubic metre.

  • Morocco awards $1bn Casablanca airport terminal deal

    19 December 2025

    Morocco’s National Airports Office (ONDA) has awarded a MD12bn ($1.2bn) contract to build the new terminal at Casablanca’s Mohammed V International airport.

    The contract was awarded to the joint venture of local firms Societe Generale des Travaux du Maroc (SGTM) and Travaux Generaux de Construction de Casablanca (TGCC).

    Construction work on the Mohammed V International airport expansion is expected to begin immediately.

    The project is slated for completion in 2029.

    The expansion will cover more than 600,000 square metres (sq m) and increase the airport’s capacity to 30 million passengers a year.

    The project is designed by a consortium comprising the local branch of French engineering firm Egis Batiment International, Morocco’s Ala Concept and UK-based RSHP Architects.

    The scope of work covers preparatory works, structural works, waterproofing, steel structural works, building facades, electrical, mechanical and plumbing (MEP) works, data centre works, HVAC systems and other associated works.

    The tender also covers the construction of a 300-key airside hotel.

    The new terminal is expected to be ready in time for the 2030 Fifa World Cup, which Morocco is co-hosting alongside Portugal and Spain.

    ONDA tendered the project contract on 4 November, with a bid submission deadline of 16 December, as MEED reported.

    In July, ONDA began early works on the new terminal building, awarding an estimated MD294m ($29m) deal for enabling works to local firm Societe de Travaux Agricoles Marocaine.

    In January, Morocco’s Transport & Logistics Minister, Abdessamad Kayouh, said that the study to expand the airport’s capacity was nearing completion.

    The project is part of Morocco’s MD42bn ($4.3bn) plan to expand key airports in anticipation of increased passenger flow for the 2030 football World Cup.

    Morocco plans to upgrade several airports, including those in Tangier, Marrakech and Agadir, increasing their respective annual passenger capacities to 7 million, 16 million and 7 million.

    There are also plans to add a new terminal at Rabat-Sale airport, raising its capacity to 4 million passengers annually, and to increase Fez airport’s capacity to 5 million passengers annually. 

    The new terminal at Mohammed V International airport will be connected to a high-speed train network linking Kenitra to Marrakech.
