A unique infrastructure project in the mountains of Saudi Arabia, a location of the future in the desert, with dams, a lake and iconic architectural works. This was commissioned to Webuild by NEOM for the Trojena mountain destination in a major contract worth USD 4.7 billion. Webuild will construct three dams to form a freshwater lake for the ski resort, as well as a series of innovative related works under a contract that places the Group among the corporations leading the development of the futuristic NEOM region. More than 10,000 people, including direct and third-party personnel, will be involved in the construction.
Webuild will also create the futuristic Bow, an architectural structure that will extend the surface of the lake beyond the front of the main dam. It will be shaped like the prow of a ship suspended over the valley, and will house a luxury hotel, as well as a residential area and a large central atrium, with accommodation and hospitality facilities.
The main dam will be made of roller-compacted concrete (RCC) and will be 145 metres high, 475 metres long and holding a volume of approximately 2.7 million m³. The second dam will also be in RCC, while the third will be in rock, with a volume of 4.3 million m³. The artificial lake will cover an area of 1.5 km² and will have an island reserved for botanical dives and walks.
The Lake, which will be the largest architecturally-crafted body of water in Saudi Arabia, is a central feature of Trojena’s LAVA designed masterplan. Sitting at the very heart of the development, it will be key to Trojena’s ambition to sustain and regenerate the area’s vibrant natural environment, offer clean, serene outdoor mountain living, and become a global hub for water sports and entertainment.

Pietro Salini, Webuild CEO said: “We are delighted and truly proud to be awarded this important project in NEOM. The 2.8 kilometer-long, man-made, freshwater lake will be a key asset in the Trojena masterplan. The project is set to be an international engineering and construction marvel and we believe our team has the global experience and expertise to deliver this exciting infrastructure project.”
Philip Gullett, Executive Director – Region Head at Trojena, stated: “The appointment of Webuild S.P.A is a significant milestone in our construction progress. We have already completed around three million cubic meters of excavation at the lake site, and we continue to excavate 90,000 cubic meters of rock per week. Importantly are implementing a sustainable approach by using all the rock excavated and reusing it for the lakebed lining and dam construction. This is crucial stage of the project’s overall development, and we are excited to see works get underway.”
For NEOM, Webuild is already constructing 57 kilometres of the Connector high-speed railway line between ‘Oxagon’ and ‘The Line’. In addition to the Connector, Webuild operations in Saudi Arabia also include Line 3 of the underground in Riyadh, which at 42 kilometres, will be the longest line on the Saudi capital’s underground network, and the ‘Diriyah Square – Package 2 Super-Basement Works’, a 10,500-space underground multi-storey mega parking facility in the new district of Ad-Diriyah. With its Fisia Italimpianti subsidiary, Webuild is also engaged in the construction and long-term management of the water treatment plant at the ZULUF onshore oil complex.
Webuild has been active in Saudi Arabia since the 1960s. It has already completed works such as the Kingdom Centre in Riyadh, which was awarded the 2002 Emporis Skyscraper Award as the world’s best skyscraper design, more than 70 healthcare facilities, and the Shuaibah-3 desalination plant in Jeddah, which was awarded the 2020 Global Water Award in the ‘Desalination Plant of the Year’ category, one of the most prestigious awards in the water treatment and desalination industry.
