Brian wondered why the pipe was used for drainage (how does it work)? How does the elevator build the piles of dirt? What are those piles of dirt for, anyway?

I think they are doing a good job on our school!

Richard's comments: They are just putting in the drainage pipe lines. The soil is very soft. They have the foundations put in. There is a lake, kind of like a swamp in part of the field. We all know there will be an elevator in the new school. "Are they cutting any more trees?" he wonders.
