Methods of building estimate

Following are the method for the calculation of estimation in the buildings.

1). Long wall & short wall method

This method is also called individual wall method, separate wall method, general

method.

In this method long wall (in longitudinal direction) is measured from outer to

outer. But short wall (transverse direction) is measured from inner to inner.

This method is very simple & accurate as compared to centre line method.

This method is time consuming.

In this method, length of long wall decreases as we more from foundation to

super structure. But short wall length increases as we move from sub-structure

to super structure.

This method is rapid method but not accurate.

In this method there is no change in total length if we move from sub-structure

to super structure.

This method is generally preferred for circular, square, octagonal (polygon)

shape without any cross wall.

This method req. Special attention at the junction point meeting point.
