The time-lapse "north-west" camera view now makes it easy to compare building heights vis-a-vis the J.W. Marriott and the Edmonton Tower. For this particular camera view, the Marriott building has reached the horizon line with the floor level (not yet poured) of the 18th floor hitting directly on the horizon line. This is roughly compared to the 16th floor of the Edmonton Tower. The two-floor discrepancy is accounted for in the difference of the floor-to-floor heights of the two buildings (although not all of them because the floor-to-floor heights of the lower six floors of the Marriott are much greater than those of the upper floors). The room floors of the Marriott are much smaller in height than the office floors of the Edmonton tower -- a ratio probably like 10:13 (roughly). Marriott will probably match Edmonton Tower height around floor 36 or 37.
