Infosys is all set to make Hyderabad its biggest campus. The IT major has firmed up plans to expand its Pocharam campus capacity to 25,000 from the present 12,000 employees. The expanded campus would be formally inaugurated in February 2016. The firm had earmarked over Rs 1,000 crore to build the facility. The first one at Gachibowli has 10,000 employees. The firm was allotted 450 acres at Pocharam about eight years ago for building the project in phases.
