I was wondering if anyone has done dropped edge beams (with 500mm) and know how much costs is expected from this. It would be helpful to know what the average costs is so that I can make a comparison when my builder gives me their quote. The maximum fill under the dropped edge beams will range from 500mm down to zero. The total length is around 18 metres (starting from half way on one side of the slab and wrap around the front of the slab).
Thanks very much!!
