Being Seattle, it can only be one thing:

I actually think it's funny that with all this hi-tech equipment and all the planning & surveying that was done, nobody could see this coming?

they should have had some sort of scans done long before this project was even started

Saw a news program about that the other afternoon.
Lots of speculation on what it could be, from the early days of Seattle.
Probably a ancient alien space craft, is my guess.  lol

I'm not worried, the same thing happened in the late 60's in England while digging a subway tunnel. Everything was fine in the end.
