Styrofoam, plumbing and a well

 Today we received the biggest load of styrofoam I have ever seen. This is laid under the entire floor area and acts as both insulation and as a raft to support the weight of the house. 

The plumbing rough-in was also completed as all the drain pipes need to be set under the cement base/floor of the house.

Also today, we got a well. Nobody knew they were coming today, but there it is and its it the correct place as well. I guess they must have consulted with the plumber who was on site at the time.
