Monkey caught a ride Northbound and did some monkeying  horsing around on our jobsite in Lake Zurich, Illinois.  The project is called, " Cedar Lake Assisted Living".  The concrete vault he climbed is a giant underground storm-water detention structure which is located under our parking lot.  The structure receives fairly extensive sub-grade preparation to ensure that it doesn't sink into the earth.

The detention structure will be located under the parking area shown in the foreground of this rendering.
