It seems that the joint between footing top portion and plinth beam is not cast properly. the reinforcement from footing top and column is not continuous.
It should be properly modified so that it will carry the desired load.
there is empty cement bag stuck in concrete at plinth beam and column joint. we should not use such material to seal the gap between shutter.
It also indicates (might be) the plinth beam had de-shutter on second day and this snap is taken.
in that case, there is no bottom support seen to plinth beam near column area.
if the curing of the concrete not done correctly, it will lead to make concrete weaker.
Here's an issue: There's currently no bearing surface under the grade beam - How will the Contractor backfill under the grade beam to insure that it has bearing capacity? With the beam currently "floating" the Contractor will need to install a flowable material under it so there is full engagement between the beam and it's substrate.
cement bags left while concreting of plinth beam at the junction of column & beam. plinth beam alignment is not proper. also bulging of beams
overall the bad workmanship. external plinth beam top above the natural ground level. refiling in footing area not proper.
