Signature engineering
Four problems that had no standard answer.
Specific technical challenges our team solved on live projects, where the method mattered as much as the result.
270metres
A tower that shortens as it stands
Advanced analysis of creep, shrinkage and elastic shortening on a 270 m tower, so the façade and MEP systems could absorb the movement.
21storeys
Removing a column from a standing building
A steel transfer truss allowed a basement column blocking vehicle access to be removed safely from a 21-storey building in service.
170metres
A crane platform in the sky
Designed a cantilever platform carrying a tower crane 170 m above ground on a landmark high-rise in Riyadh.
