The previous photo hints at the apparent wood-steel hybrid of the column, but this view of the base shows it more clearly. What is most likely happening is that the spaces between the flanges in the steel column (it is the same shape as the beam above, just turned 90 degrees) are filled with wood pieces. This gives the impression that the steel is a sleeve on two sides of a wood column; it also creates a strong balance between wood and steel in the overall design.
