ROUGH COST ESTIMATE OF BUILDING
EXAMPLE: Prepare Rough Cost Estimate of Building from given Line Plan. Cost
of Construction is Rs 900/Sqft. Cost for Water Supply, Sanitary, Electricity and Gas
Supply should include separately and Cost for Contingencies also is included.
SOLUTION:
01 Figure
02. Sides AB = CD = 30.25ft

DETAILED ESTIMATE OF SEWER PIPE LINE
Work out the quantities of all item of work for laying 400ft sewer line having18inches inner diameter and 01inche thick RCC pipe including 3ft wide and 4ft
deep trench below ground level provide 6inch thick PCC (1:4:8) in the bed.
Calculations:
Length of sewer pipe line = 400ft
Width of trench = 3ftDepth of trench = 4ft
Thickness of bed concrete = 1:4:8 = 6inches = 0.5ft
Inner diameter of sewer pipe = 18inches = 1.3ft
Thickness of pipe = 1ft
Outer diameter of sewer pipe = 18+01+01 = 20inches = 1.66ftLength of each sewer pipe = 06ft
No of sewer pipes = 400/06 = 66.66 NOS = 67 NOS

Prepare detailed estimate of a 200 meters long sewer pipe line, the length of a pipe is
2meters having 22centimeter internal dia and 2.5centimeter thickness, the slope of a
sewer pipe line is 1:300.
Calculations:
Length of Sewer Line = 200 metersLength of Sewer Pipe = 2 meters
Internal Dia of Pipe = 2.5 cm
Thickness of Pipe = 22+2.5+2.5 = 27cm = 0.27 meters Number of Pipes Required = 200/2 = 100 NOS
Number of Joints in 200 meters Long Sewer Pipe Line = 200 – 1/2 = 99 NOS
Thickness of PCC 1:4:8 = 30 cm = 0.3 metersDepth of Trench of Initial Point = 1.8 meters
Slope of Sewer Line = 1:300
Extra Depth of End Point due to Slope = 2/3 = 0.66 meter Total Depth at the End = 1.8 + 0.66 = 2.46 meters
