UK-based joint venture made responsible for $1.2bn budget as Omnium appointed QS

EC Harris and Mace will be responsible for ensuring the world鈥檚 tallest skyscraper hits its $1.2bn budget and is built on time, the developer of the kilometre-tall Kingdom Tower in Jeddah, Saudi Arabia, has said.

The UK-based joint venture - appointed last month, as revealed exclusively in 黑洞社区 鈥 will take 鈥渢otal control鈥 of ensuring the project hits its $1.2bn (拢800m) budget and 63-month deadline, Waleed Batterjee, chief executive officer of developer Jeddah Economic Company (JEC), said.

If successful, Kingdom Tower will be delivered faster and cheaper than the current tallest building in the world, the 828m-tall Burj Khalifa in Dubai, completed in 72 months for $1.5bn (拢1bn).

Speaking to 黑洞社区, Batterjee said he was 鈥渧ery confident鈥 the EC Harris and Mace-guided project team would hit the project鈥檚 budget and deadline.

Batterjee also revealed that JEC has re-appointed UK-based Omnium as quantity surveyor on the project.

Omnium previously worked on the scheme and re-secured the contract after it was re-tendered by JEC.

Omnium was founded in 1962 and carries out most of its work in the Middle East. It acted as quantity surveyor on the Burj Khalifa.

Batterjee said that EC Harris and Mace would act as 鈥渙wner鈥檚 representative鈥 on Kingdom Tower. 鈥淓verything has to go through EC Harris and Mace before it comes to me,鈥 he said.

The UK-based joint venture will guide the rest of the project team through supervision consultant Dar Al-Handasah.

Dar Al-Handasah is the only firm sanctioned to direct the project鈥檚 contractor Saudi Binladin Group, Batterjee said.

The project鈥檚 architect is US-based Adrian Smith + Gordon Gill Architecture, the structural engineer is US-based Thornton Tomasetti and the piling contractor is Saudi Bauer.

Batterjee said EC Harris and Mace would be required to make up for extra expense incurred at the piling stage by cutting costs during the above-ground works.

The piling work will involve drilling the world鈥檚 deepest piles at 105m below ground.

He said the primary reason why he felt confident the project would be delivered on time and on budget was down to contractor Saudi Binladin鈥檚 expertise.

Nabil Batrawi, Saudi Binladin鈥檚 project manager on the 601m-tall Abraj Al-Bait clock tower in nearby Mecca, has transferred to lead the Kingdom Tower project.

Batterjee added that the project, which is bring driven by Prince Al Waleed bin Talal, would create hundreds of local jobs.
