Having review this is a high-rise building 12 stories, my point of view as below;
1) The distance between column to column quite widen 27’ & 30’ (9, 10 m. width)
2) They will use hammer pile foundation system which is not suited to high-rise building 12-stories, normally should be use drilled pile foundation
My point of view, it’s not quite sure they really submitted to YCDC or not? because seeing from drawings no evidence to prove it e.g. no signed by licensed engineer, no detailed of owner.
For your information and advice krub.
