Why does a bird fly? |
| An essential feature for being able to fly is the composition of its bones. Bird’s bones have evolved to a highly efficient structure. A hard shell and struts formed by multiple cavities, appropriately located give the bone a stability equivalent to solid bones. The result is an efficient structure that has less mass and requires less force to lift. |

| It’s in the air – a bird flies. |

Design principle |
| Remove the non working dead load, maintain biaxial strength. In concrete, create a hard shell with struts through the use of appropriately located cavities formed by void formers. |

Cobiax flat slab - international Patents |
| Void plastic formers are placed between the upper and lower static reinforcement of a concrete slab. They displace concrete in zones where it has no structural benefit. The result is a floor that weighs up to 35% less compared to solid slabs of equivalent dimensions and imposed loads. |
