"The model for the proposed 522-feet tall statue of the 'Lauh Purush' would be 30-feet tall. On the basis of the model the statue would be raised," famous sculptor Ram Vanji Sutar told PTI.
The proposed statue of India's first Deputy Prime Minister Sardar Vallabhbhai Patel is Prime Minister Narendra Modi's brainchild.
Sutar said he was contacted by L&T company three months back to construct the bronze-model.
The 90-year-old artist is working on the model at his Noida studio with his son Anil Kumar.
Sutar said he considers his contribution in the making of the world's tallest statue as his life's biggest achievement.
