Progress on the foundation

There's been a lot of progress on the house over the last week!

First, the men working on plumbing, electricity and hvac all placed pipes and tubes that will be under the slab.  This includes electric conduits to every room, incoming water and outgoing sewage, and a pipe for the ground source heat pump.  Here is Frida posing with some electric conduits and water pipes in the kitchen.

 After all the pipes were placed and checked by the city inspector, a truck with a gravel shooter sprayed rocks in and around the house.  They deposited several inches of gravel.

 Here's Ella playing with the gravel.

 Once the gravel was all placed, then Jeff and Jimmy spent all day placing 2 layers of R20 high density foam.  It took a long time because they had to cut little holes for every pipe and tube sticking out of the floor.

This foam is one way that our house is different from most homes.  In typical home construction there is no foam under the floor, but insulation here actually makes a big difference in how a house performs from an energy standpoint.
