Cambodia Airports will expand the terminals at Phnom Penh and Siem Reap airports to allow them to cope with strong passenger growth.
Last year, over 2 million passengers passed through Phnom Penh, an increase of 13% year on year, while Siem Reap handed 2.2 million passengers, an increase of 21%.
The company is currently in the final stages of the conceptual design phase of the terminal expansion projects, which will add approximately 20,000m² (215,000ft²) to the terminal area at Phnom Penh and 15,000m² at Siem Reap, says a spokesman.
Construction at both terminals will commence in June and will be completed in 2015.
In June 2012, the company said that it hoped to expand the two terminals to bring their capacity up to 4 million passengers per annum.
Cambodia Airports is 70% owned by French construction and management group Vinci, with the remainder held by Cambodian-Malaysian joint venture company Muhibbah Masteron Cambodia.
