Non-Conformance in work due to Proper compaction not done for Footing PCC.

Footing and ground structure are designed for ground with an assumed or
known ground bearing pressure, If there is a loose spot at the bottom of the excavation, It must be removed. Levels can be made up with crushed stone, sand or sometimes
low strength concrete.

We generally use concrete as blinding to seal and protect the surface of bearing stratum, this also
provides a firm base for erection, shuttering or block wall true to line and level.

And as our site is near to sea it’s not worth to ignore proper compaction so we will redo it again
after proper preparation.
