Why Burj Khalifa’s Foundation Needs Electricity

burj khalifa stands 828 metres tall, but its most surprising engineering system is hidden deep beneath the ground. its foundation requires a continuous low-voltage dc supply to protect the steel reinforcement from corrosion caused by dubai’s highly saline groundwater. this video explains how engineers constructed 192 deep foundation piles in loose desert soil, how friction helps support the enormous weight of the tower, and how polymer slurry prevented the boreholes from collapsing during construction. it also explores the buttressed core structural system, the aerodynamic spiral shape, vortex shedding, concrete pumping up to extreme heights, mechanical floors, lightning protection and the reason the upper section can safely sway during powerful winds. main topics covered in this video burj khalifa foundation and pile construction continuous dc supply and cathodic protection buttressed core structural system wind resistance and vortex shedding concrete pumping to extreme heights lightning protection system mechanical floors and building services
