They installed a 20T tuned mass damper on Level 41

We recently had Gradient Wind Engineering at Richards and Drake to hoist a 20T Tuned Mass Damper up to Level 41.
Because of the tower's long, slender shape, it catches wind like a sail. Without intervention, that sway could be disorienting for residents and potentially make them feel seasick. This damper is precision-tuned to the structure's resonant frequency, acting as a kinetic shock absorber to cancel out the motion.
