Q:how many days does it take to make 1000 paper cranes?
It depends on how many people are making them. Depending on skill it takes about 2-5 minutes to make a crane. If you dedicate 5 hours a day that makes 7-50 days if one person is making them. Cranes are often made for memorial. It is a Japanese tradition, especially for Hiroshima. You make 1000 cranes as a memorial for the lost lives. She should definitely get her friends to help.

Q:how do they take crane off top of building?
Depends on the building. Either a taller crane is brought in to lift them, or they're lifted by helicopter. And sometimes a building effectively builds itself, and the crane moves up with the construction platform after being constructed at ground level. Will still need a helicopter to remove it of course.

Q:what is the ground bearing capacity required for a crane weighing 300t 100t lift.?
This depends on the angle of the lift and the distance away from centre of the crane. With the lift at tipping range all 400t will be distributed along the outer half of the pad or on the extreme legs. Rule of thumb is all the load is placed under the one pad. so one pad is 9 sq metres and the load is 400 tonnes so the bearing capacity must exceeds 400/9 tonnes per square metre. 44.44444t/m^2
