Pour Concrete into Piers

What happens here

At each pier location, workers carefully tip the wheelbarrows to pour the concrete directly into the cylindrical pier forms. The video indicates that approximately seven wheelbarrows of concrete are required to fill each 4-foot-deep pier. The concrete is poured until the form is completely filled to the desired level, typically followed by some form of consolidation (like vibrating or tamping, though not shown) to remove air bubbles.
