At least three contracting groups submitted revised prices on 2 May for the 1-kilometre Kingdom Tower on the outskirts of Jeddah.

According to sources close to the project, the confirmed bidders include the following groups:

• El-Seif Engineering & Contracting (local) and Six Construct (Belgium)
• Saudi Binladin Group (local)
• Saudi Oger (local)

The project client, local investment firm Kingdom Holding, originally asked the contractors to submit their final lump sum prices in March (MEED 15:3:10).

Kingdom says it plans to award the contract by the end of May.

US-based Adrian Smith & Gordon Gill Architecture was selected to design the 1-kilometre tower in March. 

Dubai-based Emaar Properties is managing the development of Kingdom Tower, as well as the surrounding 23-square-kilometre Jeddah Kingdom City for the local Kingdom Holding Company.

If Kingdom Tower goes ahead, it will be almost 200 metres taller than Emaar’s 828-metre Burj Khalifa in Dubai.  

Kingdom Tower will also be more than 400 metres taller than Saudi Arabia’s tallest building, the 577-metre tall Makkah Clock Royal Tower, which is scheduled for completion in August this year (8:3:10).
