How to Calculate Estimate using Center Line Method
We have a plan of three rooms. Center to center length and breadth are required and utilized when calculating estimate of a room.
In the plan, length = 5 m and breadth = 4.5 m
Also, three rooms are of same dimension.
Thickness of wall = 0.3 m
In the section, there are three steps, PCC, DPC
PCC thickness = 0.20 m
Height of three steps = 0.30 m
PCC breadth = 1.05 m
First step breadth = 0.75 m
Second step breadth = 0.60 m
Third step breadth = 0.45 m
Wall breadth =0.30 m
Center to center length of long wall = 15.9 m
Length of short wall = 4.80 m
Long wall = 2 x 15.9 = 31.9 m
Short wall = 4 x 4.80 = 19.20 m
Overall length = 31.9 m + 19.20 m = 51.1 m
Height of DPC = 0.0381 m
