These details come with limitations, generally not applicable to steel columns supporting double storey section, can you show the whole page which may have additional notes?

If the rebate is supporting studs/steel column, I recommend you to get the Engineer check the photo and confirm it can take the load or provide rectification, the rest of honey combing needs to be patched to provide enough cover to reinforcements, again this need to be addressed by the design engineer.

Min. is 300+85, the height will be specified by your structural engineer and not soil tester, in your case it should be 300pods + 100 slab thickness which is better.
