The long wall short wall methods are used to estimate the quantity of different work. In this method, the longer walls in a building (generally in one direction) are considered as long walls and measured from out to out and the shorter walls in a perpendicular direction to the long walls are considered as short walls and are measured from in- to-in for a particular layer of work.
To calculate lengths of long wall and short walls determine first their center to center lengths individually from the plan. Then the length of the long wall out to out may be calculated after adding half breadth of a wall at each end to its center to center length.These lengths of long and short walls are multiplied separately by the breadth and height of the corresponding layer and are added to get the quantity. Such length of long and short walls varies in every layer of footing.Length of the long wall out to out = Centre to center length + half breadth on one side + half breadth on another side.
