i am also a contractor... i know why nagcollapse... it always happen naman, not because of cheap materials... because of construction workers who is doing the roofing or painting something and they fell of the ceiling, cyempre masisira yun, then papalitan yun buo nanaman... one single pagkakamali... tsk tsk...
theories from a legal perspective . . . the ceiling falling down looks intentionally done (malice involded); why? only the ceiling panel fell, while the truss structure holding this doesn't seem to be structurally compromised.
why?
the contractor Takenaka Corp. wants to be paid the remaining balance of US$75M before the Phil. gov't. even opens NAIA3 for commercial operations. (Did Takenaka do this? we don't know.). Has Takenaka exercise a contractors lien on the facility?
or
to operate NAIA3, the Phil. gov't has to pay P3.2 billion for writ of possession with the balance of just compensation to be determined (& settled?) within 60-days. Maybe the gov't realized that they can generate the needed P3.2Bn by Friday-March 31 but don't have enough funds for the balance (around US$320M) so they have to save face by propping up an incident to delay the opening of the airport (while they source the funds from whomevers coffers)
