We are providing structural design services for Jeddah Tower, which will become the world’s tallest building at more than 1,000 meters, and will be the first man-made structure to reach 1 kilometer in height. It forms a mixed-use centerpiece of Kingdom City, a 23-million-square-meter urban development.

A High Performance Structural System

Jeddah Tower’s structural system is based on stringent performance criteria for supertall structures, utilizing both international performance standards and regional building codes. Key challenges of the project include establishing wind loads appropriate for the location and building height, producing a building form that minimizes wind loading while optimizing the structural system, design of the slender spire elements, and design of a foundation system that supports the heavy loads and mitigates differential settlement.

A Mixed-Use Giant

Jeddah Tower, at 530,000 square meters, will house an opulent hotel, luxury condominiums, serviced apartments, office space and an observation deck. A high-performance exterior wall system will minimize energy consumption by reducing thermal loads. Each of the tower’s three sides will feature a series of notches that create pockets of shadow shielding areas of the building from the sun and providing outdoor terraces with stunning views of Jeddah and the Red Sea.

Tall & Supertall

Pioneers in the design of high-rise buildings, we use advanced analysis to optimize structural systems, resolve interdisciplinary conflicts, and guard the safety and comfort of occupants. For structures of unconventional size, shape, structural system or function, we employ performance-based design methodologies when prevailing building codes are inapplicable or inadequate, such as in high-seismic areas. Our deep bench of seasoned professionals combines unequalled experience with sophisticated technological tools to enrich the creative process, promote effective collaboration, improve coordination and enhance visualization and communication throughout planning, design and construction.
