The gypsum board is being transfered into the building through the opening. We can see the structure of the building exposed through the weather proofing. Under the weather proofing we can see the sheathing which is used to tie the building together -connecting all the sections into one cohesive unit. Also visible are the rim joist of the 2nd and 3rd floors and the floor joists of the 3rd floor ( because the ceilings haven't been put up yet)
Manufactured doors delivered to the site, going to be installed on the 1st floor. The jambs are the vertical parts of the door, the head is the top, and the threshold is the part on the floor. The hinge attatches the movable door to its frame (2 hinges on each door)
This picture also shows the foundation of the building. We can see the cement foundation coming above ground level, at the top of the foundation sits the sill plate.
Looking closely we can also see one of the stakes that was used to mark the original foundation.

On the exterior 2 men we nailing the felt paper on to the ledge that is set up to frame the brick veneer, the vapor barrier is meant to prevent the leakage of water into the building. The paper is nailed to the wall and is turned up following the shape of the ledge. The felt paper is being put up over the rigid insulation, and under the weather proofing.
