Some useful methods for estimating building works

The following method are useful for working out various building quantities like earth work, foundation concrete, brickwork in plinth and super structure etc.
a) Long wall – short wall method
b) Centre line method.
c) Partly centre line and short wall method.
a) Long wall-short wall method: Under this method, the wall along the length of room is treated as long wall whereas the wall that is situated vertically to long wall is called short wall. To find out the length of long wall or short wall, initially compute the length of centre line for separate walls. Then compute the length of long wall, (out to out) once half breadth at each end is added to its centre line length. Therefore, the length of short wall is calculated into in and is built by subtracting half breadth from its centre line length at each end. The length of long wall normally declines from earth work to brick work in super structure whereas the short wall enlarges. In order to obtain quantities, multiply these lengths with breadth and depth.
