now, finally i've seen the only machine. yea on the buildingplace they have one. it doesn't make holes, doesn't nail, no it pumps the concrete into the fifth floor. well finally i thought that there has to be something on this building site which is moved by a motor instead of pure handwork.
next week they will have the sixt floor and it still makes fun to watch the place growing, somehow a pitty that i won't see the top of the place...
