IKAC (Imam Khomeini Airport City) is located in Southern Tehran, Capital City of Islamic Republic of Iran. The main objective to carry out such a mega-development project is to convert the airport to an international "Air Hub" in the region. From site selection point of view, IKAC's location is unique, and enjoys the geo-strategic advantages of the country – its natural and physical endowments like oil and natural gas, educated and skilled human resources and a growing domestic market. The initial site selection and design was done a long time ago, but no serious steps were taken until 1987. From then onward, the civil activities started, and in 1990 essential revisions became inevitable and therefore a new Master Plan for aviation zone was prepared by the joint venture of Iranian and Dutch consulting firm of NACO+3T. Construction of Passenger Terminal 1 commenced in 1995 and it was inaugurated officially in 2005 and received flights from since then. IKAC is owned and operated by Imam Khomeini Airport City Company.
