The completion deadline for the RM 4 billion Kuala Lumpur International Airport 2 (KLIA2) has been further postponed to April 2014. Design changes and other construction setbacks such as unexpected ground conditions that required additional piling have been cited as the key reasons for the delay. KLIA 2 that is being constructed as a low-cost carrier terminal is expected to become operational in May 2014. According to Malaysia Airport Holdings Berhad (MAHB), the company responsible for the construction and operations of the airport, 90 per cent of the project is already complete and costs have not risen substantially despite the delay. The airport was originally scheduled to become operational in 2012; since then, several extended deadlines have remained unmet, the latest being June 28, 2013.
