RCC Pile Foundation
System Components		Initial Cost Structure

Critical Factors	Tools Used	DO'S	DON'T'S
1.Depth of pile and number of reamers 2. Quality of soil 3. Water table level 4. Clear cover of concrete to reinforcement	1. Crow Bar 2. Spade 3. Basket 4. Reamer 5. Tape	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
Construction Process
Set out the location for bores	Mark the area for pile foundations	Dig the bore to 30cm deep using crow bar	Wet the bore and dig with reamer
Apply force over the reamer for digging bore	Remove the mud from reamer at regular intervals	Dig the bore to the required depth	Check the depth of the bore
Tie the reinforcement	Place the reinforcement in the bore	Fill the bore with cement concrete
