How Many?

How many men does it take to build a 120 room hotel?

Answer 4 (Two in cherry pickers, one in a large crane, one to load the crane on the ground) admittedly that is only for the steel work, more workers will be required to finish it off.

This new hotel is being built opposite my work and is going to change the traffic load around the area quite significantly, but it will look just like my work, a black mirror glass block.
