The construction team developing the Trojena dams for Saudi Arabia’s NEOM development has surpassed a major engineering milestone: 1 million cubic meters of roller compacted concrete (RCC) placed to date.
The figure marks roughly 25% of the total RCC required for the project’s main and secondary dams, according to project personnel. The milestone was achieved in approximately 18 months of continuous progress.
Webuild, the Italian engineering and construction group, is leading the dam package.
The following cumulative work statistics have been shared by site engineers:
- 687 days of continuous activity
- Average workforce: 5,348 people (with peaks reported above 7,000)
- More than 9.6 million m³ of earthworks completed
- 280,000 m³ of conventionally poured (CVC) concrete placed
- Over 55,000 hours of workforce training delivered
- Personnel representing 41 nationalities currently on site
The RCC achievement comes as part of Webuild’s US$4.7bn contract, signed in early 2024, to build three dams and related infrastructure that will create Trojena’s planned 2.8km freshwater lake. The lake will be central to the mountain destination’s masterplan and a key feature ahead of Trojena hosting the 2029 Asian Winter Games.
The main dam is designed to reach 145m in height with a volume of 2.7 million m³ of RCC, while a second dam will also use RCC and a third will be constructed as a 4.3 million m³ rockfill structure. According to NEOM, excavated material from the surrounding mountains is being reused for dam and lakebed construction to reduce environmental impact.
Webuild’s scope also includes The Bow, a large architectural structure that will project over the valley and host a hotel and residential facilities.
The company stated that more than 10,000 workers – including direct and third-party personnel – will be involved throughout the duration of the contract.
