As per the sculptor Ram Sutar’s original design, the statue was to have a poised countenance, with Patel’s head held high and arms by his sides emitting a feeling of power as well as warmth. Since Patel’s face was an important aspect, special care was taken in casting the facial features that had to be as close as possible to the Sardar’s face. The walking pose also opened up a gap of 6.4 meters between the two feet which then had to be tested to withstand wind velocity.Īnother challenge came in the form of the look of the statue. This goes against the norms of what other tall statues have followed. The Sardar’s legs are clad in a dhoti, his feet in chappals and in a walking pose that means that the statue is most slender at the base. The SoU can also survive earthquakes measuring up to 6.5 on the Richter Scale, at a depth of 10 km and within a radius of 12 km of the statue. In any given situation, all the four corners of the base raft remain rooted to the ground. To arrest any sway of such a tall structure, two Tuned Mass Dampers of 250 tonnes each have been used. The challenge is not only of the wind blowing against the statue but the succession effect it creates at the back of the statue that had to considered in the structural design. The statue has been engineered to withstand wind speeds of up to 50 m per second (almost 180 km/hr. ) could buffet the statue in a worst-case scenario. Studies of wind patterns over the years revealed wind speeds of 39 m per second (roughly translated into 130 km/hr. Situated right in the middle of the river Narmada, the statue is exposed to the tunnel effect of winds blowing down the river. Natural factors like wind and earthquakes posed stiff challenges.

A viewing gallery at the 135 m level, at the chest, can accommodate up to 200 visitors at one go and affords a breath-taking view of the dam and its environs.The vertical cores support the steel frames to which about 6500 bronze panels are clad.The structure has two vertical cores, each housing a high-speed passenger elevator.It has a unique, slender width to height ratio, far more exacting than existing technical norms, that calls for special engineering considerations.It rises out of a star-shaped, geometric base that covers the entire Sadhu Hill.The statue is conceived as a naturalistic depiction of Sardar Patel in characteristic garb in a walking pose.
