Centre Line Method (Ex. 6)

Estimate of the quantities of the items 1to 5 by centre line method is as given beloW i
) Total centre line length of all 30 cm walls Total centre line lengths of two long walls
and two outer short walls of the right side rooms (combined) and ofthe three walls of
the remaining room (square room) = (2 x 9.20 + 2x 3.90) + (3x 3.90) = 37.90 m.
Numbers of junctions are two with 30 cm walls.
(i) Total centre line length of 20 cm inter wall =3.90 m.
Numbers of junctions are two with 30 cm walls.
(ii) Total centre line length of all20 cm walls of front and back verandah =Total centre line
length of the front verandah long walland side wall and of the back verandah long
wall and side wall = (3.90 + 2.00) + (3.90 + 2.70) = 12.50 m.
Numbers of junctions are 8(4 with 30 cm walls and4 with 30cm pillars).
(iv) Total length of parapet wall, over outer walls of right side rooms and over outer walls of
square room = Right side long wall+front and back outer walls +(walls bythe right
side of front and back verandahs) +(outer walls of square room + front andback
square room) = (9.50 + 2 x 4.00 + 2.40 + 2.50) + (4.20 + 2 x 3.90) = 22.40
+ 12.00 =34.40 m.
