Question { 7971 }

if the length and breath of footing is 1.2m x 1.2 m what
will be the length and breath of foundation trench

Answer

Am not agree with the above posted answer because,
as we all know you can not dig the exact paper size trench
practically on ground,
so, answer could be = length of Footing + extra pcc length
(if not considered then also its Ok)+ extra digging portion
(depends on excavater for its better working)
= 1.2 + 2 X 0.150 + 2 x 0.300
= 2.1m
So Length/Width of trench = 2.1 X 2.1 m
