1. The document describes the long wall and short wall method for calculating quantities of building construction items like brickwork, plastering, and flooring. 2. It explains how to calculate the centerline length and actual length of long walls and short walls by adding or subtracting half the wall thickness at each end. 3. The lengths are then multiplied by the width and height/depth as needed to determine the quantities of different construction items like brickwork, plastering, and flooring for the building.

SESSION: 03 LONG WALL AND SHORT WALL METHOD
Example:
2. Find out quantities of following items of work
i. Superstructure brick work ii. Plastering iii. Flooring
Wall thick-0.3 m
Procedure:
1. To get length of long wall or short wall, calculate first the center line length of
individual walls.
Example: Refer above diagram for detail
Center to center distance of long wall = Length of wall + ½ width of left side wall +
½ width of right side wall
= 6.0 m + ½ x 0.3 + ½ x 0.3
= 6.3 m
Center to center distance of short wall = Length of wall + ½ width of left side wall +
½ width of right side wall
= 6.0 m + ½ x 0.3 + ½ x 0.3
= 6.3 m

2. Then the length of wall, (out to out) calculated after adding half breadth at each side
or end to its center line length. (This is applicable for long wall only)
Example:
Length of long wall = c/c distance of long wall + ½ width at each side
= 6.3 + ½ x 0.3 + ½ x 0.3
= 6.6 m
3. Thus length of short wall measured (in-to-in) calculated after deducting half breadth
of each side or end to its center line length. (This is applicable for short wall only)
Example:
Length of short wall = c/c distance of short wall - ½ width at each side
= 6.3 - ½ x 0.3 - ½ x 0.3
= 6.0 m
4. These lengths are multiplied by breadth and depth to get quantities of individual item
of work.
