(b) half breadth of wall on each side

(d) length of the wall

This question was posed to me in a job interview.

My question is taken from Estimate of Three Roomed and Sixed Roomed Building in portion Methods of Building Estimate & Estimate of Building of Civil Engineering Drawing

Answer 1

The correct option is (b) half breadth of wall on each side

To explain: This method is used for deriving quantities of different items of work in a load bearing structure. The wall that contains lengthiest length on plan is considered as “long wall” and all the walls parallel to the certain long wall (regardless of length) are also taken as long walls. The wall that is perpendicular to the direction of long wall is taken as “short wall” alias “cross wall”.
