Muted public spending hinders global tunnelling

4 April 2025

 

This package also includes: Traffic drives construction underground

The pipeline of tunnel construction projects around the world as tracked by GlobalData stands at $1.3tn, encompassing projects from announcement to execution.

The total pipeline value reflects the overall values of projects that are either entirely tunnels or that have tunnels as an integral part of the work. The project pipeline includes tunnelling works across a range of sectors, including road and railway development, as well as water and sewerage.

The pipeline of tunnel construction projects around the world currently stands at $1.3tn

Subdued spending

Public spending is anticipated to remain muted globally in the short term, as governments are still trying to curtail expenditure to reduce public debt, thereby constraining investments in public infrastructure. This is affecting the demand for tunnel construction, which heavily relies on public infrastructure development. Elevated construction material prices, high interest rates and labour and skill shortages are expected to discourage new investment, further reducing demand for tunnel construction.

These challenges have already impacted project viability, leading to the withdrawal or postponement of funding for 50 projects in Australia’s $78.6bn infrastructure investment programme due to cost increases of over $21bn. The conflicts in Russia and Ukraine, the situation in Gaza and disruptions to shipping in the Red Sea are weighing on new investment levels, particularly in Eastern Europe and the Middle East and North Africa region due to increased uncertainty.

However, this decrease in new tunnel investment is not expected to be uniform globally, as China’s significant infrastructure investment drive, the US’ Infrastructure and Jobs Act and India’s various infrastructure investment programmes are driving new investment in their respective regions.

> Middle East and North Africa (Mena)
The Mena region has a tunnel construction pipeline valued at $128.6bn. The UAE is one of the leading markets, with $25.4bn of projects that are mainly for metro systems and water and sewage tunnels. Across the region, economic factors like high debt and lower oil revenues may hinder the progress of these projects in the future.
> Western Europe

Western Europe has a tunnel construction project pipeline valued at $329.5bn, with Switzerland leading with $60.6bn of projects, follwed by Germany with $56.8bn. Notable projects include the Turin-Lyon tunnel and the Genoa underwater tunnel. Projects in pre-execution and execution stages total $222.8bn, with the highest-value project being Zurich’s $38.8bn CST (underground cargo) Freight Metro Tunnel.

> Northeast Asia

Northeast Asia’s tunnel construction pipeline is valued at $327.7bn, with China contributing $220.3bn, including the $42.4bn Dalian-Yantai undersea railway tunnel. Japan has projects worth $101.3bn, primarily the $65.2bn Tokyo to Nagoya Maglev Railway Line. Most projects are in later development stages, totalling $198.3bn, or 69.8% of the pipeline.

> Australasia

Australasia’s tunnel construction pipeline totals $150.1bn, with Australia holding $112.9bn, about 75% of the region’s value. The largest project is the $87bn Melbourne Suburban Rail Loop, a 90km rail loop with 13 stations. Construction on six stations began in 2022, with the entire project expected to finish by 2050, though rising costs and labour shortages may affect this.

> North America

North America’s tunnel projects are valued at $92.4bn, with $63.6bn in pre-execution and execution stages. The pipeline includes 921.8km of tunnels, primarily in the US. Railway tunnels are the largest segment at $40.7bn, with the Hudson River Rail Tunnel being the highest-value project at $16bn.

> Southeast Asia

Southeast Asia’s tunnel pipeline is valued at $91.3bn, with $55.1bn under construction. Singapore leads with $45.2bn, mainly from rail tunnel projects. The Land Transport Authority awarded a $199m contract for tunnels connecting MRT stations as part of the Cross Island Line’s second phase.

> Eastern Europe

Eastern Europe’s pipeline is valued at $56.3bn, with $46.9bn in pre-execution and execution stages. Major contributors include Turkiye, Czechia and Romania, which has the largest share at $16.3bn. The $9bn Bucharest Metro Line 5 is a key project expected to complete by 2033, with spending projected to rise in the coming years.

> South Asia

South Asia’s tunnel construction pipeline is valued at $47.9bn, with India contributing $31.9bn, primarily from road tunnels. A notable project is the $1.3bn Thane to Borivali underground tunnel. The pipeline includes 2,043.7km of developments, with spending expected to reach $1.8bn in 2024.

> Latin America

Latin America has a growing tunnel construction pipeline valued at $30.3bn, with $28.7bn in later development stages. The region includes 276.2km of projects, with Colombia leading at 92.1km. The highest-value project is the $9.6bn Bogota Metro, which began construction in early 2021.

> Sub-Saharan Africa

Sub-Saharan Africa’s tunnel construction pipeline is valued at $6.7bn, with 63.7% in pre-execution and execution stages. The pipeline includes 1,580km of projects, primarily in Tanzania, Ethiopia and Kenya. Spending may reach $685.4m in 2025, but investment constraints may limit new projects.

In conclusion, while the global tunnel construction industry faces challenges due to muted spending, high construction material prices and geopolitical uncertainties, significant infrastructure investment initiatives in countries like China, the US and India are expected to continue driving new investment.

  • Regional rail industry emerges

    Read the December issue of MEED Business Review

    The GCC is experiencing a fundamental shift in its approach to rail infrastructure, as it moves from standalone projects to a self-sustaining regional industry. The transition is evident as local, national and regional projects advance across the region.

    The first wave of metro systems, in Dubai, Doha, and most recently, Riyadh, have reported stronger-than-expected ridership and demonstrated the viability of mass transit in the Gulf.

    Extensions to those networks are planned or under way, including Dubai’s Blue and Gold lines and Riyadh’s Line 2, alongside planned metros elsewhere such as Muscat and Bahrain.

    Projects are also planned and already being delivered at the national level. The UAE’s Etihad Rail and Saudi Arabian Railways are leading most of these efforts. The region’s first cross-border project is also progressing with the Hafeet Rail scheme linking the UAE and Oman.

    Other cross-border schemes are planned, including high speed links connecting Riyadh with Doha and Kuwait City, and rail links for Bahrain across causeways to Saudi Arabia and Qatar. The ultimate ambition is a GCC Rail network – a project that was reinvigorated by the Al-Ula accords in 2021.

    Sustained, simultaneous activity across the GCC is fostering the development of an indigenous regional rail industry. Rather than being executed as isolated endeavours, projects are creating ongoing demand for expertise, personnel and resources within the region.

    Project delivery capability will be complemented by the establishment of crucial ancillary services, including fabrication and servicing facilities.

    These operations will shift the GCC from a lucrative market for international contractors to a regional hub for the rail industry, capable of servicing and sustaining its growing network.

  • Aldar and Mubadala plan $16bn financial district expansion

    8 December 2025

    Register for MEED’s 14-day trial access 

    Abu Dhabi's sovereign wealth fund, Mubadala Investment Company, and local developer Aldar have established a joint venture to deliver an expansion of the financial district on Al-Maryah Island with a gross development value of AED60bn-plus ($16bn-plus).

    The development will be built on the undeveloped land bank on the north side of Al-Maryah Island, covering about 500,000 square metres (sq m), and will support the next phase of growth for Abu Dhabi Global Market (ADGM).

    The masterplan encompasses 1.5 million sq m of new office, residential, retail and hospitality floor space.

    In an official statement, the firms said that the core objective of the project is to support the continued expansion of ADGM, Abu Dhabi’s international financial centre. ADGM now has more than 11,000 active licences registered in the free zone and is among the fastest-growing financial hubs globally.

    "Nearly 40,000 people are already based within the district, and demand for space remains strong," the statement added.

    The Al-Maryah Island expansion will add over 450,000 sq m of Grade A office space, doubling the island’s current office inventory.

    The expansion will add over 3,000 residences on the waterfront.

    The next phase will also add a further 40,000 sq m of retail and dining spaces.

    A central feature of the expansion is the Al-Maryah Waterfront enhancement project. This will include a bay fountain capable of water displays up to 75 metres high, forming the focal point of a reconfigured waterfront with additional dining, leisure and event spaces designed to complement existing assets on the island.

    Three new bridges are proposed to link the north side of Al-Maryah Island with Reem Island and the Abu Dhabi mainland, reducing travel time to Saadiyat Island to under 10 minutes.

    The enabling works on these projects are due to begin in 2026.

    The new joint venture is owned 60% by Aldar and 40% by Mubadala.

    "The two organisations are close to completing the legal work on a retail joint venture that will own and operate several of Abu Dhabi’s leading retail destinations, including The Galleria Al-Maryah Island, Yas Mall and the planned Saadiyat Grove Mall," the statement added.

  • Visa agrees to support digital payments in Syria

    5 December 2025

    Visa and the Central Bank of Syria have agreed on a strategic roadmap that will allow the US-based card and digital payments company to begin operations in Syria and support the development of a modern digital payments system.

    Under the agreement, Visa will work with licensed Syrian financial institutions under a phased plan to establish a secure foundation for digital payments.

    The early stages will involve Visa supporting the central bank in issuing Europay, Mastercard and Visa (EMV)-compliant payment cards and enabling tokenised digital wallets – bringing the country in line with internationally interoperable standards.

    Visa will also provide access to its platforms, including near-field communication (NFC) and QR-based payments, invest in local capacity building and support local entrepreneurs seeking to develop solutions leveraging Visa’s global platform.

    “A reliable and transparent payment system is the bedrock of economic recovery and a catalyst that builds the confidence required for broader investment to flow into the country,” noted Visa’s senior VP for the Levant, Leila Serhan. “This partnership is about choosing a path where Syria can leapfrog decades of legacy infrastructure development and immediately adopt the secure, open platforms that power modern commerce.”

    The move marks one of the most significant steps yet in Syria’s slow and uneven return to the formal global financial system and carries implications that reach beyond just payments technology.

    It lays the groundwork for overturning more than a decade of financial isolation in which Syria has operated largely outside global banking and settlement networks.

    Visa’s entry will not erase all existing barriers – as many restrictions remain in force and will continue to shape what is practically possible – but its support signals a reopening of channels that could smooth Syria’s reintegration into financial networks.

    The involvement of the US-based payments provider is also a further tacit sign of the US government’s enthusiastic bear hug of the new post-Assad Syrian government under President Ahmed Al-Sharaa.

    For investors assessing long-term opportunities, the presence of a globally recognised payments operator will provide reassurance that Syria’s financial system is returning to international norms, and the security and transparency that comes with it.

  • Meraas announces next phase of Nad Al-Sheba Gardens

    5 December 2025

    Dubai-based real estate developer Meraas Holding, which is part of Dubai Holding, has announced the eleventh and final phase of its Nad Al-Sheba Gardens residential community in Dubai.

    It includes the development of 210 new villas and townhouses and a school, which will be located at the northwest corner of the development.

    The latest announcement follows Meraas awarding a AED690m ($188m) contract for the construction of the fourth phase of the Nad Al-Sheba Gardens community in May, as MEED reported.

    The contract was awarded to local firm Bhatia General Contracting.

    The scope of the contract covers the construction of 92 townhouses, 96 villas and two pool houses.

    The contract award came after Dubai-based investment company Shamal Holding awarded an estimated AED80m ($21m) contract to UK-based McLaren Construction last year for the Nad Al-Sheba Gardens mall.

    The project covers the construction and interior fit-out of a two-storey mall, covering an area of approximately 12,600 square metres.

    The UAE’s heightened real estate activity is in line with UK analytics firm GlobalData’s forecast that the construction industry in the country will register annual growth of 3.9% in 2025-27, supported by investments in infrastructure, renewable energy, oil and gas, housing, industrial and tourism projects. 

    The residential construction sector is expected to record an annual average growth rate of 2.7% in 2025-28, supported by private investments in the residential housing sector, along with government initiatives to meet rising housing demand.

  • Frontrunner emerges for Riyadh-Qassim IWTP

    5 December 2025

     

    Saudi Arabia’s Vision Invest has emerged as frontrunner for the contract to develop the Riyadh-Qassim independent water transmission pipeline (IWTP) project, according to sources.

    State water offtaker Saudi Water Partnership Company (SWPC) is preparing to award the contract for the IWTP "in the coming weeks", the sources told MEED.

    The project, valued at about $2bn, will have a transmission capacity of 685,000 cubic metres a day. It will include a pipeline length of 859 kilometres (km) and a total storage capacity of 1.59 million cubic metres.

    In September, MEED reported that bids had been submitted by two consortiums and one individual company.

    The first consortium comprises Saudi firms Al-Jomaih Energy & Water, Al-Khorayef Water & Power Technologies, AlBawani Capital and Buhur for Investment Company.

    The second consortium comprises Bahrain/Saudi Arabia-based Lamar Holding, the UAE's Etihad Water & Electricity (Ewec) and China’s Shaanxi Construction Installation Group.

    The third bid was submitted by Saudi Arabia's Vision Invest.

    It is understood that financial and technical bids have now been opened and Vision Invest is likely to be awarded the deal.

    The Riyadh-based investment and development company made a "very aggressive" offer, one source told MEED.

    In November, the firm announced it had sold a 10% stake in Saudi Arabia-based Miahona as part of a strategy to reallocate capital "towards new and diversified investments".

    The company did not disclose which projects the capital might be reallocated towards.

    As MEED recently reported, Vision Invest is also bidding for two major packages under Dubai's $22bn tunnels programme in a consortium with France's Suez Water Company.

    The Riyadh-Qassim transmission project is the third IWTP contract to be tendered by SWPC since 2022.   

    The first two are the 150km Rayis-Rabigh IWTP, which is under construction, and the 603km Jubail-Buraydah IWTP, the contract for which was awarded to a team of Riyadh-based companies comprising Al-Jomaih Energy & Water, Nesma Group and Buhur for Investment Company.

    Like the first two IWTPs, the Riyadh-Qassim IWTP project will be developed using a 35-year build-own-operate-transfer contracting model.

    Commercial operations are expected to commence in the first quarter of 2030.
