01 February 2022
Diriyah Development Company (DevCo), a development subsidiary of Saudi-based Diriyah Gate Development Authority (DGDA), has awarded its largest contract to date worth SR3.99 billion ($1.06 billion) to Salini Saudi Arabia for the construction of its ‘super basement’ car park.
Salini Saudi is a unit of The Webuild Group, a leading global player in the construction of large, complex projects for sustainable mobility, clean hydro energy, clean water, green buildings.
The state-of-the-art three-level underground car park supports the commercial heart of the culture and heritage giga project’s Diriyah Square.
The mixed-use district will offer a combination of leisure and entertainment, ultra-luxurious hotels, retail, Grade A offices and residential units designed in the traditional Najdi architectural style, set for completion in 2024. It also includes the King Salman Grand Mosque.
Nearly 1 million sq m in floor area, the car park hosts an intricate network of underground roads and tunnels situated below Diriyah Square with multiple access points, with the capacity to accommodate 10,500 cars.
On the contract award, DGDA Group CEO Jerry Inzerillo said: “Diriyah Square’s forthcoming underground car park is an integral component of our development’s design, ensuring beautification and safety within our urban pedestrian spaces for visitors and the local community.”
“An estimated 9,000 local jobs will result from this aspect of the project, further contributing to His Royal Highness The Crown Prince Mohammed bin Salman’s Vision 2030,” he added.
A key feature of the parking facility allows for a continuous flow of traffic and integration with the existing road network in Riyadh. The clever road system will directly connect commuters with all of Diriyah’s destinations, including Wadi Hanifah, the Western Ring Road, and a National Motorway, and will be a key component of the City of Riyadh Arterial Road System.
The car-park structure is an intricate undertaking that will connect to the existing road and bus network and will include over 2 km of four-lane tunnels.
Salini will be responsible for the detailed excavation and backfill for the three-level underground foundation construction inclusive of all mechanical, electrical and plumbing, fire, safety and fit out.
The structure will support 700,000 sq m of concrete, 90,000 tonnes of steel reinforcement and 1,600,000 sq m of formwork.
On the big win, The Webuild Group said the contract awarded is the core of the whole project. It includes civil and structural works, tunnels and other connections for the district’s huge car park.
The Diriyah Gate Development will oversee the creation of a district along the Western Ring Road in northwestern Riyadh that will cover 7 sq km. The architecture and design of the district will take inspiration from the traditional Najdi style. It will include the development of a network of pedestrian streets, public squares, courtyards, souqs and bazaars to recreate the authenticity of a Saudi village, it added.
