Shown above is a view of the crane over the school with Central Park in the background.
You might also notice in the bottom right of the photo the almost total demolition of the rear portion of Graham House almost to the ground floor. The stair and elevator core can be seen still intact running the vertical length of Building 16, as well as the facade of Graham still intact. All is on schedule.
Below are a series of close up photographs of the chiller units being lowered into place.
