             Critical Factors 
              
            1. Depth of pile and number of reamers  
            2. Quality of soil  
            3. Water table level  
            4. Clear cover of concrete to reinforcement 
             | 
            
             Tools Used 
              
            1.   Crow Bar                         4. Reamer 
            2.   Spade                             5. Tape 
            3.   Basket

            | 
             1. Pile should be cast immediately after boring  to avoid collapse of bore wall  
             
            2. Depth of pile should be checked properly  
             
            3. Concrete should be properly compacted  
              
             | 
            
             1. Fine sand should not be used for concreting  
             
            2. Concrete should not be used for a designload  
                  more than 80 tones
