'Suspended concrete ground floor' vs 'Ground supported concrete floor'?

THERE ARE MANY ADVANTAGES OF CHOOSING A SUSPENDED CONCRETE GROUND FLOOR OVER A GROUND SUPPORTED CONCRETE FLOOR, THIS IS ALSO COMMONLY KNOWN AS A "GROUND BEARING SLAB OR OVERSITE". 1) IF THERE ARE ANY AREAS OF BACKFILL THIS WOULD HAVE TO BE REMOVED AND FILLED USING COMPACTED TYPE1 OR SIMILAR IF USING THE SLAB METHOD 2) INSTALLING A SUSPENDED CONCRETE FLOOR IS NOT WEATHER DEPENDANT 3) NORMALLY THERE IS LESS MATERIAL TO MOVE/HANDLE 4) ON SLOPING SITES OR AREAS WHERE A HIGH FLOOR LEVEL IS REQUIRED THE SUSPENDED FLOOR WOULD SAVE A SIGNIFICANT AMOUNT OF FILL MATERIAL

I agree that a suspended floor is more practical in certain areas over a concrete slab or over site concrete however if the suspended floor is constructed of a cavity inner wall of damp course (doc)there would be no problem of damp
