Jeddah Tower reaches 454 metres as Saudi Arabia targets 2028 completion

Saudi Arabia’s Jeddah Tower has reached 113 floors and 454 meters, marking another major milestone in the construction of what is set to become the world’s tallest building.

The tower reached its latest height on September 2, according to project updates, adding to significant progress since construction resumed in January 2025. The project is targeting completion in August 2028.

When finished, Jeddah Tower is expected to rise more than 1,000 meters above Jeddah’s Red Sea coastline. It will overtake the Burj Khalifa in Dubai, which stands at 828 meters and has held the world height record since 2010.

The pace of construction has picked up considerably this year. In March, the tower stood at around 370 meters and level 91, with Kingdom Holding reporting an average five-day construction cycle and around 5,200 workers involved across the project. The September milestone puts the tower another 84 metres higher than in the March update.

Saudi Binladin Group is leading construction as the tower climbs through its next structural phase.

The scale of the project is also creating an unusually demanding construction environment, requiring structural, façade and building systems work to progress as the tower becomes increasingly narrow and exposed to wind.

The next phase will require the project team to maintain its construction pace while simultaneously progressing through structural work, façade installation, MEP systems, and testing and commissioning.

Engineering becomes more challenging at greater heights, where stronger winds place additional demands on the structure.

Jeddah Tower’s three-wing, tapering design is intended to manage those forces. As the tower rises, its floor plates progressively narrow, reducing the impact of wind on the building.

German fastening specialist Fischer is supplying steel and chemical fastening systems for the project, with specialists supporting contractors on site through construction. The company has previously supplied products for projects including the Burj Khalifa, Ain Dubai and Louvre Abu Dhabi.

Work is also advancing beyond the tower’s concrete structure. Façade fabrication was underway by March, with cladding installed across more than 10 floors, while mechanical, electrical and plumbing works were progressing through office levels seven to 14.

Thornton Tomasetti is providing structural engineering services, with Adrian Smith and Gordon Gill Architecture behind the design.

The project had also accumulated more than eight million working hours without a lost-time incident as of the latest update. Jeddah Tower is being developed by Jeddah Economic Company as the centrepiece of Jeddah Economic City on Saudi Arabia’s Red Sea coast.

The mixed-use development is planned to include a Four Seasons hotel, apartments, offices and luxury condominiums, alongside an observatory positioned high above the city and Red Sea.

The tower is planned to have a gross floor area of 243,866 square meters, according to the Council on Vertical Urbanism.
