Bridge Park construction site

A number of buildings are going up on the northeast corner of Route 161 and Riverside Drive, just east of the Scioto River. A roundabout is taking shape southwest of the buildings. The square blue tower going up on the left is actually gray cinder block, continuing upward to four or five stories high. Maybe it will hold the elevator shaft. The building in the middle--behind the eah mover--is dark interior space between white-edged planes of floors and ceilings. The light building to the rear on the right, with outer walls, has made the most progress. The smaller piles of earth have become one large pile off to the eastern edge. The main site is level, lighter soil.  Darker, rough clods tumble down the outer sides.

Do they use GANTT charts for this? If so, how many does it take? How big are they? Just thinking of it is a little overwhelming.

This was an experiment, with watercolor added on site, then color pencil (blended with alcohol) applied at home. The orange plastic fence blurred into the orange and white barrels.  This view may be too complicated for the timeframe I had.  (Previous attempt to sketch.)
