The Indian government chose the design of the German architectural company Gerkan, Marg and Partners. Renovation of the stadium started in 2007. Nearly 4,000 construction workers worked on the stadium in double shifts. The substantially remodelled and modernised stadium was inaugurated on 27 July 2010. The stadium was given a new roof, improved seating, and other new facilities to meet international standards to allow it to host the athletic events and the opening and closing ceremonies of the 2010 Commonwealth Games. The capacity of the stadium was reduced from 78,000 to 60,254. The cost of the renovation was around US$150 million (₹961 crores).
