GRR only goes around it.

They actually did this twice just to make sure the ground was real compact!! They piled it up, left it for a little while, then cleared it away. Then put it all back.

It's called surcharging, and we did it on the bridge project I'm currently working on it the Bay Area. <I see. Because it seems that building on top of a big pile of dirt would be kind of dangerous in an earthquake.> Only if the pile is not placed properly (i.e. compacted between lifts) or the weight of the building is not evenly distributed on the pile. A real tall structure can be stabilized (i.e. given a lower center of gravity) by driving pile (long slender pieces of steel or concrete encased steel) into the ground. That's what we did for our bridge abutments (the beginnings and endings of the bridges).
