This design guide presents state-of-the-art practices in voided slab construction. The concept centers on removing concrete mass from the areas of the slab where it is not structurally efficient; thus reducing the dead load by as much as 35%. This floor system allows for large, clear spans and efficient overall slab thicknesses. Innovative structural slab construction practices have taken the efficiency of traditional slab systems to new heights.
