Central line method
It is one of the methods for preparing an estimate.
Calculation of length of the wall is done first, and then multiply it with the breadth and depth of the wall to find out quantity.
This is a method that is suitable for rectangular, circular buildings having no inter or cross walls. Hence it is suitable for a wall having the same width.
Calculation:
Center to center length of wall = 5 + 0.3 = 5.3 m
Center to center width of wall = 4 + 0.3 = 4.3 m
So, Total centre line perimeter = 2 × 5.3 + 2 × 4.3 = 19.2 m
Total volume of brickwork = Total center line perimeter × width of wall × height of room - Volume of door opening
Total volume of brickwork = 19.2 × 0.3 × 3.5 – 1.2 × 2 × 0.3 = 19.44 m3
