What are the different machinery used for excavation ?

Following are the machinery used for excavation

 

JCB Machine

1. JCB Machine
2. Rock Excavator – L&T Case machine
3. Porclain Machine

What is the output of the Porclain Machine ?

The output of the porclain machine is calculated as 50-60 m3 / hour.

What is the output of Hydraulic Excavator ?

According to the CPWD code, the output of a Hydraulic Excavator is 20 CuM/hour for Ordinary Rock and 30 CuM/hour for all other soil.

How is per m3 excavation costing is calculated ?

Cost of excavaion depends on the following factor

1. Type of rock
2. Depth of excavation to be done
3. Type used :- Machines or Manual labor are to be used.

For doing excavation of about 15 cm, for an area of 100 m2 ; we would require 13 labours;  and approx cost would be around Rs 4600 for 100 m2. or in cubic meter sense; it would be around Rs 400/m3 for excavation.

but for example, if we have to do with mechanical means for a depth of more then 30 cm; then we will use hydraulic excavator. The per hour output of hydraulic excavator is 30 Cubic meter; assuming a hire charge of 8000 per day , with loader hire charges of 5000 Rupees per day;  The cost comes out to be Rs 147/ Cubic Meter.
