Every building has a foundation. The bigger the structure the deeper the foundation.The architect and construction manager survey the land before any work is started.
It is decided how many workers were needed, where to start digging and how much material should be used…all prior to building the foundation.

A few years ago I saw some plans for an addition my brother-in-law was adding on to his home. Most amazing to me was that the plans even showed where each builder would stand as the foundation was built. Every detail counts.
I once heard that a father asked the Chofetz Chaim at what age does chinuch for a child begin? His answer was to that chinuch starts when the child is born.
