BENGALURU: Software giant Infosys is all set to build the world's tallest free-standing clock tower at its 345-acre global education centre in Mysuru.

At 135 metres, the proposed tower will be taller than Big Ben (96 m) in London, Hoover Tower (87 m) in California and McGraw Tower (53 m) in Cornell, Times of India reported on Tuesday.

The tower, to be built in Gothic style to meld with the classical look of the other buildings in the campus, will have 19 floors and a board room at level seven. It will be erected from a 22x22 metre base. The company estimates the project to cost about Rs 60 crore and take 20 months to complete.

The tower has been designed by Hafeez Contractor, the Mumbai-based architect who also designed Infosys' Mysuru campus. LERA, a New York-based firm of structural engineers is providing structural consultancy services for the tower, which is being built by Bengaluru-based KEF Infra.
