Yet, How do you calculate rate per m3 for excavation?

1. So, 10 cu.m. work for = 0.050 Days required. As per Backhoe Excavator =Tractor/Dumper.
2. The cost of a Backhoe excavator machine for 10 m 3 = 0.050 Day x 7000 Rs. ( This took in CPWD)
3. As per the same calculation for Tractor/Dumper = 0.050 Day x 2000 Rs. ( This took in CPWD)
