Jeddah Tower Surpasses 100-Story Mark as Construction Pace Quickens

Construction teams at the Jeddah Tower site in Saudi Arabia confirmed this week that the structure has surpassed 100 floors. This latest development follows a period of accelerated activity after work on the site resumed in early 2025.

Engineering firm Thornton Tomasetti, providing structural design services, noted that the tower now exceeds 400 metres in height. This progress places the project roughly halfway toward its final objective of reaching at least 1,000 metres.

The skyscraper is intended to be the first human-made structure to reach a full kilometre in height. Upon reaching its final elevation, it will stand more than 170 metres taller than Dubai’s Burj Khalifa, which has held the record for the world’s tallest building since 2010.

The project site became active again last year following a seven-year halt that began in 2018. Since January 2026, when the tower was reported at the 80-floor mark, crews have added 20 stories in less than four months.

Jeddah Tower is the central feature of the Jeddah Economic City, a large-scale development covering 57 million square feet. The project is designed by Adrian Smith + Gordon Gill Architecture, the same firm responsible for the Burj Khalifa.

The structural system uses a buttressed core configuration with reinforced concrete. This design consists of a triangular central core with three wings that radiate outward to provide lateral stiffness against wind loads.

According to Jeddah Economic Company, the tower will be a mixed-use facility featuring a luxury hotel, residential units, and office space. It is also designed to house the world’s highest observation deck, situated at an altitude of 630 metres.

Current schedules suggest the building will reach completion in 2028. While work on the concrete structure continues, installation of the exterior facade cladding is also underway to maintain the current delivery timeline.

Project management is being handled by Turner International, with Saudi Binladin Group serving as the principal contractor. Other partners on the development include Dar Al-Handasah, Langan, and RWDI.

The acceleration of the Jeddah Tower comes as Saudi Arabia expands its portfolio of vertical infrastructure projects. Reports indicate that other proposals, including a potential two-kilometre tower in Riyadh, are currently under consideration within the Kingdom.

For now, the focus remains on the Red Sea coast where the Jeddah Tower structure is becoming a permanent fixture of the regional skyline. Engineers indicate that the next phase of construction will involve increasingly complex logistical coordination as the tower enters its upper tiers.
