Long Wall and Short Wall Method

LONG WALL AND SHORT WALL METHOD

 In this method, the wall along the length of room is considered to be long wall while the 

wall perpendicular to long wall is said to be short wall. To get the measurement of materials

and works length of long wall or short wall, calculate first the center line lengths of

individual walls. Then the length of long wall, (out to out) may be calculated after adding

half breadth at each end to its center line length. Thus the length of short wall measured

into in and may be found by deducting half breadth from its center line length at each end.

The length of long wall usually decreases from earth work to brick work.in super structure

while the short wall increases. These lengths are multiplied by breadth and depth to get

quantities. 

EXAMPLE 

Estimate the quantities of following items of a two roomed building as shown in figure 1

a. Earthwork in excavation in foundation trench

b. Lime concrete in foundation

c. First class brick work in 1:6 cement mortar in foundation and plinth

d. 2.5 cm thick DPC (1:2:4) with water proofing compound

e. 1st  class brick work in cement mortar superstructure

The dimensions of doors, windows and selves are

Door D = 1.20 m × 2.10 m. 

Windows W = 1.00 m × 1.50 m

Shelves S = 1.00 m × 1.50 m
