Anybody has any idea where the error is introduced?
Meaning
A) foundation , beams , are not in position, ie error by 3%.
B) different methods of measurement differ by 3%.
if A) Not sure whether 3% is allowed in industrial facilties.
oopps, the position of the machine is wrong by 3%. Need to redo the piping
.
Anyway, it looks like none, AMK excepted, actually ask for surveyor's results. Don't actually check whether we get what we paid for.
So if I was a developer, I would built according to BCA plans, my sales brochure shows extra space by 3% in aircon ledge, balcony. Make them shorter but same width
.
if the law permits that I can charge them extra by overbuilding, I would enlarge the AC ledge
hopefully, the government can tighthen to rein in misrepresentation by the developers.
