Explanation:
Reshoring is a set of supports for lower floors while upper floors get poured, it is the process of utilizing multiple levels of shores below the story being cast to distribute the applied construction loads to multiple stories.

Reshoring helps distribute the weight of the concrete that is to be poured on an upper flow evenly within nthe lower floors.
