Vision 2030 drives tall tower plans

2 October 2023

Commentary

As work restarts on Jeddah Tower, economists and historians will revisit the theory, known as the Skyscraper Index, that the completion of record-breaking towers coincides with recession.

The notion that completing extreme skyscrapers and economic downturns are correlated is a longstanding debate.

The origins of the Skyscraper Index can be traced back to the early 20th century. In the 1920s, the completion of the Chrysler Building (pictured) and the Empire State Building in New York coincided with the Great Depression. The correlation then repeated itself when the Petronas Towers in Malaysia were finished during the Asian financial crisis in the late 1990s.

Then in 2008, construction work for the Burj Khalifa in Dubai was in the final stages as the global financial crisis crippled the emirate’s property market with debt.

There are three broad reasons commonly used to explain the phenomenon. The first is overconfidence and speculation. Building tall towers is an expensive venture, which means the decision to go ahead with them is typically made during a period of economic exuberance. The danger is that this exuberance can also create speculative bubbles that may burst before tall towers are completed.

The likelihood of bubbles bursting before completion is increased by the second reason for the correlation: long construction periods. Record-breaking towers take a long time to plan, design and construct, and during the time between their conception and completion, the economic landscape inevitably changes.

The third reason is the misallocation of resources. In boom times, investors are prone to chasing higher returns without fully assessing the risks. Pouring resources into large building projects is often an example of such misallocations, and when economic corrections occur, these projects can become symbols of excess.

The head start means Jeddah Tower should comfortably be completed before 2030

Improved fortunes

Jeddah Tower has restarted during a period of economic exuberance for Saudi Arabia. Oil prices are riding high, with Brent crude trading at nearly $95 a barrel at the end of September. While output cuts mean the Saudi economy is technically in recession, the performance of the non-oil sector remains robust and record levels of project spending are expected to be achieved by the end of this year.

How long it will take to complete Jeddah Tower is not yet clear. While the tower is a major undertaking, it does have some advantages over a new project. It has already been designed, and the foundations and one-third of the superstructure have been completed.

This head start means that the tower should comfortably be completed before 2030. This will be crucial because Riyadh has committed to completing projects worth hundreds of billions of dollars as part of Vision 2030, and this spending should help cushion Saudi Arabia’s economy from any storm clouds and headwinds that may be gathering elsewhere in the world.

  • Parsons wins role on Elon Musk-backed Dubai Loop project

    4 May 2026

    US-based Parsons Corporation has been appointed to deliver programme management services for the Dubai Loop transportation system.

    The contract was awarded by Elon Musk-backed firm The Boring Company, which signed a construction agreement with Dubai’s Roads & Transport Authority (RTA) in February.

    Parsons’ scope of work includes independent design verification, stakeholder management, permitting and no-objection certificate (NOC) support, and multidisciplinary design reviews for the project’s first phase.

    The first phase comprises a 6.4-kilometre route with four stations, linking the Dubai International Financial Centre (DIFC) and Dubai Mall.

    Stations will be located at DIFC 2, ICD Brookfield Place, Dubai Mall Zabeel Parking and Burj Khalifa.

    The first phase is expected to cost about AED565m ($154m) and to be delivered within one year after design work and other preparations are completed. Tunnelling is expected to begin in the second half of this year.

    Next phase

    The second phase will connect Dubai World Trade Centre and DIFC with Business Bay.

    The tunnels will extend up to 22km and include 19 stations.

    The total cost across both phases is expected to be around AED2bn ($545m), with completion scheduled within three years.

    The pilot route is expected to serve around 13,000 passengers a day, while the full route is projected to have a capacity of about 30,000 passengers a day.

    The RTA and The Boring Company signed a memorandum of understanding on the sidelines of the World Governments Summit in Dubai in February last year to explore the development of the Dubai Loop transportation system.

    The Dubai Loop is expected to be similar to The Boring Company’s Las Vegas Convention Centre (LVCC) Loop project. The LVCC Loop is a 2.7km underground tunnel system that connects different convention centre halls, reducing walking time across the site to about two minutes.

    The LVCC Loop has been in operation since 2021. It uses Tesla Model 3 cars to carry passengers between five stations. The Boring Company began construction in November 2019 at an estimated cost of $49m.

  • Humain tenders infrastructure for 6GW data centre campus

    4 May 2026

    Saudi artificial intelligence (AI) infrastructure company Humain, owned by the Public Investment Fund (PIF), has issued a tender inviting firms to develop infrastructure for its planned 6GW hyperscale AI data centre campus in Riyadh.

    The project will be delivered on an early contractor involvement (ECI) basis. Under the ECI process, selected contractors are required to submit methodologies and design proposals, after which one team will be selected to deliver the construction works.

    Firms have until 8 May to submit proposals.

    The development will be built on a 24-square-kilometre site in the Al-Saad area in east Riyadh. It will be delivered in two phases across six plots, each with a capacity of 1GW.

    The scope of infrastructure work covers:

    • Construction of 380kV/132kV/33kV electrical distribution network, two substations with a capacity of 500MVA and 200MVA, bulk supply point (2,000MVA)
    • Water network and fire protection systems
    • Sewage treatment plant and wastewater network
    • Stormwater systems
    • Roads
    • Underground cable and fibre optic networks
    • Landscaping works

    The client is being supported by Canadian engineering firm Hatch, France’s Egis and US-based firm JLL.

    Humain was launched in May last year to operate and invest across the AI value chain.

    Humain is building full-stack AI capabilities across four core areas: next-generation data centres, hyper-performance infrastructure and cloud platforms, and advanced AI models, including Allam.

    Also in May 2025, Humain signed preliminary deals with US chipmakers AMD and Nvidia to build multibillion-dollar advanced digital infrastructure in the kingdom.

    AMD said it will invest up to $10bn to deploy 500MW of AI compute capacity in Saudi Arabia over the next five years.

    In October, PIF and Saudi Aramco signed a non-binding term sheet setting out key terms under which Aramco would acquire a minority stake in Humain, with PIF retaining majority ownership.

  • Abu Dhabi selects consortium for 2.5GW Taweelah C IPP

    4 May 2026

     

    Register for MEED’s 14-day trial access 

    A consortium of Al-Jomaih Energy & Water Company (Saudi Arabia) and Sembcorp Industries (Singapore) has been selected to develop the Taweelah C independent power producer (IPP) project in Abu Dhabi.

    The consortium will sign a power purchase agreement (PPA) in mid-May, a source told MEED.

    The combined-cycle gas turbine (CCGT) plant will have a capacity of 2.5GW. It will be located at the Al-Taweelah power and desalination complex, about 50 kilometres northeast of Abu Dhabi city.

    It is understood that China Energy Engineering Corporation (CEEC) will be the engineering, procurement and construction (EPC) contractor.

    Last September, MEED reported that state offtaker Emirates Water & Electricity Company (Ewec) had received three bids for the facility.

    The bidders included:

    • Al-Jomaih Energy & Water Company / Sembcorp Industries
    • Sumitomo Corporation (Japan) / Korea Overseas Infrastructure & Urban Development Corporation / Korean Midland Power
    • Korea Western Power Company / Etihad Water & Electricity (UAE) / Kyuden International (Japan)

    At the time, Mohamed Al-Marzooqi, chief asset development and management officer at Ewec, said the bids would make Taweelah C “one of the lowest tariff CCGT projects in the region”.

    The carbon-capture-ready facility had been scheduled to begin commercial operations in the fourth quarter of 2028.

    This was based on the initial timeline for a PPA to be signed in the fourth quarter of 2025.

    Taweelah C is part of Ewec’s wider programme to support the UAE’s Net Zero by 2050 Strategic Initiative and the Abu Dhabi Department of Energy’s Clean Energy Strategic Target 2035.

    Ewec plans to raise solar power capacity to 18GW and wind capacity to 2.6GW by 2035, while reducing the carbon intensity of its power generation by more than half compared to 2019.

    Ewec is also expanding its low-carbon water desalination capacity, with the Taweelah reverse osmosis (RO) plant already operating as the world’s largest RO facility and additional projects, such as the Mirfa 2 RO and Shuweihat 4 RO, under way.

    By 2030, it expects 95% of Abu Dhabi’s installed water capacity to come from RO technology.

  • Dubai launches Blue Line metro tunnelling works

    4 May 2026

    Dubai has announced the launch of tunnelling works for the Dubai Metro Blue Line extension project.

    In a post on X, Sheikh Mohammed Bin Rashid Al-Maktoum, UAE Vice President, Prime Minister and Ruler of Dubai, announced the start of operations of the tunnel boring machine (TBM), which the Roads & Transport Authority (RTA) has named ‘Al-Wugeisha’.

    The TBM is 163 metres long, weighs more than 2,000 tonnes and will operate around the clock. The post added that its average excavation rate ranges from 13 to 17 metres a day.

    The Blue Line will connect the existing Red and Green lines. It will be 30 kilometres (km) long, with 15.5km underground and 14.5km above ground.

    The line will have 14 stations, seven of which will be elevated. There will be five underground stations, including one interchange station, and two elevated transfer stations connected to the existing Centrepoint and Creek stations.

    In December 2024, the RTA awarded a AED20.5bn ($5.5bn) main contract for the construction of the project to a consortium comprising Turkiye’s Limak Holding and Mapa Group, along with the Hong Kong office of China Railway Rolling Stock Corporation (CRRC).

    The consortium is responsible for all civil works, electromechanical works, rolling stock and rail systems. After completing the project, it will assist with maintenance and operations for an initial three-year period.

    According to an official statement, the Blue Line will have a capacity of 46,000 passengers an hour in both directions.

    The project is scheduled for completion in September 2029.
