Pile eccentricity will allowable up to maximum 75mm. Above that we can proceed pile cap works by increasing the size of pile cap.

Concrete piles cannot be driven at precise intended location; This is true for bored piles also. For practical reasons various country design codes restrict the permissible deviation. In Indian code this value is specified as 75 mm. This plays important role in pile-cap design. The deviation smaller than this will never be reported. So pile cap sizing needs to be based on the worst possible direction deviation. The pile eccentricity is one of the important aspects in pile cap shear strength calculation as well as pile cap reinforcement calculation.
For ingestion the maximum permissible intake is 7 picograms.
Permissible Exposure Limits (PELs) are maximum permitted exposure levels established by the US Occupational Safety and Health Administration (OSHA).
The maximum permissible concentration of mercury in air is 0,1 mg/m3.
