Here, I describe the more common methods of taking out quantities in the Length of long wall measurement decreases while length of short. This construction video is recorded on the topic of long wall and short wall method. Both the methods are useful for load bearing structure. In centre line method, estimate of works for the walls of the building can be done at the same time. Whereas in long wall short wall method, each wall is.

## Methods of takeoff quantities – Explanation with solved problem - Basic Civil Engineering

No doubt, this method is quick as compared to the method described above but there may be mistake of long wall short wall method particularly at junction. For each junction half breadth of the respective item of footing is to be deducted from the total center length.

Thus in case there is one partition wall which have two junctions, deduct one breadth of trench or concrete from the total center length i.

These lengths of long and short walls are multiplied separately by the breadth and height of the corresponding long wall short wall method and are added to get the quantity. Such lengths of long and short walls vary in every layer of footing. This method is described as follows, First, find out the lengthy wall they are the long wall and wall perpendicular to that is short wall.

## Estimation of Building - Long Wall Short Wall, Center Line Method.

Methods of Estimation of Building. Estimation of a building can be done by different methods as follow.

Long Wall — Short Wall Method. Long wall — Short wall Method. In Long wall — Short wall method of estimation, the external wall along the length of the room is intended to be Long wall while the wall perpendicular to the long wall is stated to be a Short wall.

To get the length of the long wall or short wall, calculate long wall short wall method the centerline lengths of the particular wall. Then the length of the long wall, out to out may be measured after adding half breadth at each end to its centerline length. Thus, the length of short wall measured into in and may be found by deducting half breadth from its centerline length at each end.

The length of the short wall usually increases from earthwork to brickwork in superstructure while the long wall decreases.

These lengths are then multiplied by depth and breadth to get quantities. In short wall and long wall method, the wall along the length of the room is considered to be a long wall, while the wall perpendicular to a long wall short wall method wall is known to be a short wall.

## Can anyone please explain the the long wall short wall and centre line method in detail? - Civil4M

In Center Line method of estimation, measurements of the wall are taken up-to center. Internal measurements are generally taken.

The thickness of half wall from one side and thickness of half wall from another side in internal measurements are added in order long wall short wall method determine the length of Center Line of room walls.

To obtain the length of long wall or short wall, initially the centre line lengths of individual walls should be computed. Then the length of long wall has to be computed after affixing half breadth at each end to its centre line length.
