Clearing lot for new building

This is across from our apartment, a view on the balcony just outside our front door.  The workers had already demolished the old house that was there previously.  Only thing left was this tree.  I thought maybe they were going to leave the tree but then one day I heard chain saw buzzing away and knew immediately they were going to take it down.  So this photo shows one worker sawing away.  Another worker is in the tractor controlling the arm to keep the tree from falling onto next building, and another worker pulling on a steel cable to pull the tree toward the cleared lot.  Soon afterwards, after the worker who was doing the sawing went toward corner of the lot near the white truck, with one big nudge from the tractor arm, the tree came crashing down.  Next day, the tree trunk was gone too.  The next several days, they have been trucking debris away.  As construction of the new building starts, I'll take occasional photos to show progress.
