I'm not an engineer but have been in the building industry for 30 years. Without seeing your engineering drawings I'd say that the slab on the right is over an open plan area and as such is often 258mm (3 course) to take the span. We had a mix of 172mm (2 course) across smaller spans but required 2...

Thanks, you quite right, the right side is an open plan. I can sleep now. Much appreciated and thanks again !!!

The engineer design say “to be 200mm”- UNO. Unless Noted Otherwise UNO The engineer notes the slab thicknesses on the engineering plan are you using 190mm wall blocks? The builder has no say in varying the slab thickness, the engineer must amend and sign his drawings? Not sure if this is normal due...
