You can see in the picture they built a temporary asphalt ramp around the manhole in the center. I’m not sure the SOP for NYC in particular, but most structures have adjusting rings sitting just below the frame/lid that you see. A crew will adjust the structures in the road to the final grade before the paver comes by. This is usually a concrete patch around the structure, either on the final grade or in a layer below so you don’t see it. That way they just pave around the structure.
Sometimes they are at the same grade now and don’t need adjustment. A company I’ve worked for also had a different specification for manholes in the middle of the road - adjusting the frame downward so it’s not sticking up of the road in the interim condition - then back up again to the final elevation.
