Neom selects three contractors for Trojena dams

28 March 2023

Neom has selected three contractors to work on the three dams that will form the central lake at the Trojena mountain resort that will host the 2029 Asian Winter Games.

The three contractors engaged on an early contractor involvement (ECI) basis are a consortium of Saudi Arabia-based Al-Ayuni with Turkiye-headquartered Limak, Beijing-based PowerChina and Italy’s WeBuild.

The ECI process requires selected contractors to submit methodologies for the project and a design proposal. The phase during which contractors work with the project team is expected to last six months.

After that period and based on the proposals, Neom will select one contractor for the 26-month contract.

It is understood that the work on roads and infrastructure leading to Trojena's three dams has already started.

MEED reported in February that the construction of the dams could cost about $2bn.

The main dam will be 145 metres high and 475 metres long at its crest. It will be built using 2.7 million cubic metres of roller compact concrete (RCC).

Some 650,000 cubic metres of RCC will be used to build a dam within the planned lake to create an island below the water level. This kidney-shaped dam will be 38 metres high and 700 metres long. It will connect to the nearby Lake Village via an underwater tunnel. The landscaping and other attractions within the dam are known as the Enchanted Forest.

The third dam will have a height of 65 metres and measure 490 metres long at its crest. It will be constructed using 4.15 million cubic metres of rockfill. The works also include the lakebed line and the foundations for the Bow Building, a concrete structure at the end of the lake that will overhang the valley below and incorporate a hotel.

The engineer for the lake is Singapore’s Surbana Jurong. The executive programme manager is US-based Aecom. US-based Bechtel was awarded the contract to provide project management consultancy services for the Trojena development at the end of last year.
