This is the ground floor you're looking at, without most of the exterior walls. Look at this diagram

See the trapezoidal columns in both the diagram and the photograph? It looks like the main lobby desk will be right where that blower with the red stripe currently is. All of the ventilation equipment you see now will go away as well as those corrugated walls. When they resume construction, all that will remain will be the structural steel and concrete. The rest of what you see now is temporary to provide HVAC, power, etc. to the sub-levels.
The utilities you see now, will go where the black areas are in this diagram. Look at the top left exterior support column in the diagram, the one that houses two stairwells. Notice how between the stairs, there are two small rectangular black spaces? Now look at the photo above, and notice how the closest vents to the camera, they both enter the structure in those same rectangular spaces?
The elevator banks will reside within the tower core, which will be inside those black capped walls.
