Kolkata Airport costs rise from from USD431.3 million to USD516.4 million

India's Kolkata Airport reportedly announced modernisation and expansion costs have risen from USD431.3 million to USD516.4 million, excluding a USD66.5 million air traffic control tower, which was included in the original cost estimate (The Hindu Business Line, 30-mar-2010). Airports Authority of India (AAI) reportedly announced plans to defer the construction of the control tower due to current cost overruns. The modernisation and expansion programme is scheduled to be completed by Aug-2011, with 40% of works already completed. Additional projects, including a baggage sorting system, have also affected cost overruns. The programme includes a 400 m runway extension and 180,000 sq m terminal expansion.
