Trojena is making significant construction progress on site as it prepares to receive the first of two tunnel boring machines (TBM) in February, which will enable the construction of Trojena’s funicular railway.
On its way from Germany, the 235-metre-long, 2,000-tonne TBM is one of two machines commissioned to bore a twin 3.8-kilometre-long time travel tunnel.
The railway will run through the side of and up the mountain and will take guests from the Mirage Visitor Centre terminal to the Vault building.
The TBM is designed and manufactured by German firm Herrenknecht.
Philip Gullett, executive director and region head of Trojena, said: “This will be the first operating funicular rail system in the kingdom and the steepest TBM-driven funicular tunnel in the world. There is a one-kilometre height difference between the start of the tunnels at the bottom of the mountain to the breakthrough point at The Vault building, so this tunnel drive is not only complex but unique.”
The machine has been procured as part of the Turkish-local joint venture Limak Holding and Al-Ayuni Investment & Contracting Company’s contract to undertake the tunnelling and excavation works for the project.
In August last year, MEED exclusively reported that Neom had awarded the joint venture an infrastructure development contract at Trojena.
The scope covers the construction of the time travel tunnel, Mirage freight depot and Vault excavation works in the Gateway cluster of the Trojena development.
The tunnel links the Mirage Visitor Centre and the Vault, Trojena’s centrepiece development.
The Mirage freight depot will be located next to the Mirage visitor centre, providing access to the underground time travel tunnel.
The Vault will be built vertically inside a hollow mountain that will fold in on itself. It will be 198 metres high, 253 metres wide and 864 metres long. The total surface area of the project is 200,000 square metres.
Trojena progress
Trojena will host the Asian Winter Games in 2029 and the construction works have been planned to meet that deadline.
At the MEED Saudi Giga Projects event in Riyadh last May last year, Gullett said: “We have procured 30% of the overall project and are preparing to procure the remaining 70%.
“The whole masterplan consists of six zones. We have already awarded some of the major contracts and the construction works have started on several schemes, most notably the Vault excavation works, tunnelling works, Ski Village and the construction of the dams at the Lake District.”
Launched by Crown Prince Mohammed Bin Salman Al-Saud, Trojena is set to be a year-round tourist destination. It will include a ski village, family and wellness resorts, retail, food and beverage facilities, and sports amenities such as watersports and mountain biking. An interactive nature reserve is also planned. The project is due to be completed by 2026.

Boutique Group tenders Tuwaiq Palace hotel in Riyadh24 April 2026

Saudi Arabia’s Boutique Group, backed by the sovereign wealth vehicle Public Investment Fund (PIF), has retendered a contract to convert Tuwaiq Palace in Riyadh into a hotel.
Contractors have been given a deadline of 31 May to submit proposals.
The scheme comprises 40 hotel rooms and suites and 56 one- and two-bedroom villas.
According to regional projects tracker MEED Projects, the contract was first tendered in 2022.
In January of that year, Crown Prince Mohammed Bin Salman launched Boutique Group to manage and convert historic and cultural Saudi palaces into ultra-luxury hotels.
Boutique Group’s first phase covers three palaces, two of which are under construction. Al-Hamra Palace in Jeddah is being converted to include 33 suites and 44 villas. In July 2023, MEED reported that Jeddah-based Al-Redwan Contracting was appointed the main contractor for the Al-Hamra Palace conversion.
The other project is the Red Palace in Riyadh, which will feature 46 suites and 25 guest rooms. In 2023, local contractor Mobco won the contract to undertake the project.
In 1957, the Red Palace became the headquarters of the Council of Ministers for 30 years, and later served as the main office for the Board of Grievances until 2002.
Jordan-headquartered Dar Al-Omran is acting as supervision consultant on all three projects.

Firms announce 129MW Dubai data centre24 April 2026
Dubai’s Integrated Economic Zones Authority (DIEZ) has signed a joint-venture agreement with Netherlands-headquartered data centre developer Volt to build a new artificial intelligence (AI)-ready data centre in the emirate.
Planned for Dubai Silicon Oasis, the development will take the form of a campus covering up to 60,000 square metres.
The project will be delivered in two phases, starting with 29MW of immediately available capacity, followed by a second phase adding a further 100MW of committed power.
Under the arrangement, DIEZ will supply the land and essential infrastructure, while Volt will finance and develop the project, lead construction, and manage the design, leasing, implementation and day-to-day operations.
French firm Schneider Electric, which has its regional headquarters in Dubai Silicon Oasis, will support the development by supplying advanced electrical systems, power distribution capabilities and smart data centre infrastructure.
The GCC currently has more than 174 active data centre projects, representing over $93bn in investment, led by international players such as AWS, Google and Huawei, alongside regional developers including Khazna and Moro, supported by government-led localisation strategies.
More than a dozen large-scale facilities valued at over $100m each are currently under tender, with further packages expected to reach the market over the next six to 12 months.
The UAE is one of the leading data centre markets, with hyperscale campuses, sovereign cloud initiatives and edge data centre deployments underway.
Data centre development is closely aligned with the UAE’s digital economy and AI roadmap, as well as the wider smart city programme.
Priorities include hyperscale and colocation facilities to support cloud service providers; edge data centres to reduce latency and enable 5G and IoT use cases; energy-efficient designs using advanced cooling, modular construction and renewables; and strategic partnerships between global hyperscalers, local developers and utilities.

Iraq signs upstream oil contract24 April 2026
State-owned Iraqi Drilling Company (IDC) has signed a contract with China’s EBS Petroleum for a project to drill 17 horizontal wells in the southeastern portion of the East Baghdad field.
Mohamed Hantoush, the general manager of IDC, said the contract signing came after a “series of successful achievements” by the company at the field.
The achievements included the completion of a project to drill 27 horizontal wells and another project to drill 18 horizontal wells, according to a statement released by Iraq’s Ministry of Oil.
In January, Iraq’s Midland Oil Company (MOC), in collaboration with EBS Petroleum, completed the country’s longest horizontal oil well in the southern part of the East Baghdad field.
The well, which was called EBMK-8-1H, reached a total depth of 6,320 metres, and had a 3,535-metre horizontal section, making it the country’s largest horizontal well ever drilled.
Senior officials from the Iraqi Oil Ministry and representatives of EBS Petroleum attended the well’s completion ceremony.
EBS Petroleum is a subsidiary of China’s ZhenHua Oil, which is focused on Iraq.
ZhenHua Oil is the operator of the field and is working with Iraqi partners to oversee the field’s development.
