hi..
I plan to extend my house DS Semi D:kitchen(1st floor) and room(2nd floor).
I would like to know recommended footing size spec.
base on tom jason, he mention 5x5 size is recommended.
I did ask one of contractor,he mention 3x3 is enough since soil is solid.

for two storey..the best is with pilling 5x5 feets...if space permit..else most contractor just use 3x3 footing...of course with piling is the best...and also depend on soil type...
the steel type is Y12 BS..is the minimum requirement...of course if you want bigger is better...usually for double storey that the standard....you dont need engineer to do that...for the case bungalow collapse is because the footing and the beam is not according to standard....but the end of the storey it depend on you...only big big company hire engineer for their reno...normal contractor just use the standard...of course if you want engineer no problem but the contractor will charge you..for normal house..contractor dont take soil sample..but of course if you want sur ecan..but they will charge you...
