Grandstand "column support footing" consist of three 50' Auger Cast, 1" rebar, & 1-/34" threaded rods.

A dedicated worker secures the "threaded bolt rods" to the center Auger Cast.

Concrete is then pumped into the framed rebar & threaded rod footings.

The plywood forms are stripped away after the "concrete cures", leaving a finish look.
