First Scott connected a heavy duty wire into the electrical panel in our basement, and ran electricity next door for their tools. This was decided upon so using noisy, expensive, gas-powered generators could be avoided.

Next the rim joist was installed around the perimeter. This is a 2x10 on edge (it is whatever size the floor joists will be). All this work is really precise, with the guys checking the diagonals often to be sure the base of the building is square, using a laser level and shims to adjust when needed to make the top of floor level.
After the rim joist was installed all the way around the perimeter, the first center girder was installed. In this case, it's an LVL -engineered lumber - stands for "laminated veneer lumber" and in the photo it is more a medium brown than the dimensional lumber, which looks almost white. The girder sits in the beam pockets in the concrete walls and is supported in the middle on concrete filled steel columns (that are red) that rest on the thickened footings that were poured with the slab floor. The girder is what holds up the floor joists, and this afternoon before they left for the day, they had installed a few floor joists that rest on that LVL and cantilever out over the foundation wall to create a bay window in the dining area.
