According to Clause 15.1 of Agreement and Conditions of PAM Contract 2006,
It is unsure whether the conditions of contract by Pertubuhan Akitek Malaysia was adopted in the construction of KLIA2 but practical completion generally carries the meaning above.
The operator of KLIA2 already has full use of the airport for its intended purposes for more than 6 months. Citing confidentiality agreements, the officer from Malaysia Airports Holdings Bhd (MAHB) could not give any specifics other than the fact that the remaining 2% of the works was contractors' failure to comply with certain criteria, including "some minor testing of the facilities and documentation",
What is so confidential?
Separately, in 1Q13, its Chairman and officer of MAHB reassured the public that KLIA2 was on-track to conclude the construction and internal works by 1 May 2013, and the airport commencement date to be on 28 June 2013. (source1, source2 ). KLIA2 eventually opened on 2 May 2014, about a year later. With just about 3 months to the targeted deadline, how could the Chairman and the officer be so ignorant, not knowing it was impossible for KLIA2 to be ready by 1H13?
