Is this structurally viable.

I saw many building in Bengaluru having 6 inch width pillars and walls so i thought its new material and cost saving but I am seeing a 10 storey apartment being constructed in the nieghbourhood with same 6 inch thick pillars so i got doubt on structural integrity of the building,most of the pillar I saw growing up were atleast 9' width .So can anyone explain on structural integrity and legality of the building.
