^ ^ that's a weird place to put the crane
The other end of the building is seemingly out of reach considering the boom length of this crane.
Maybe a second crane is coming? Twinsies??
or
Maybe one of the less expensive cranes which exist as an extension of the building as it rises?
My favorite observation, however, is why they choose that particular corner. I re-examined the render on page 1... The crane is clearly being erected just left of the eventual vertical rise, where a glass-clad two story section serves to "communicate" with its existing three story brick neighbor. How cute. Probably one of this projects final punch list items when the crane is down and off their payroll!
If you aren't understanding what I'm seeing, its the short glass portion just behind the second street tree (from left) in the render - a portion which just so happens to be similar in width to the tower crane's support column.
