The man working is a carpenter and is working by the emergency light because the lights in the building have not been turned on yet.
This is opening by which the gypsum board was being transfered and we can see the stacks on the right. The header of the opening and the studs of the wall are visible, as is the plumbing work. The cavity on the left could be an elevator shaft, the cables are clearly visible.
This is the interior of a stairwell, we can see the framing of the walls -the rim joist of the 2nd floor and the steel studs of both the 1st and 2nd floors. The man that is walking is steping onto the landing between the 1st and 2nd floors.
Between the steel studs there is wood blocking for the handrail. The handrail on the left has more elements, the balusters are the vertical members, and each articulated member is a post(it isnt butted up against a wall, but an empty cavity -unsafe, needs the balusters and posts)
From this angle we can also see a stringer of stairs leading up to the 2nd floor, the treads are the horizontals and the risers are the verticals.
This is the view of a window from the interior, the weather proofing that is nailed to the exterior is pulled through the rough opening before the prefabricated window is installed. The main frame is made up of the head, the side jambs and the sill. The sash is the window frame that holds the panes of glass, it is made up of the horizontal members -rails, and vertical members -stiles. Connecting the panes of glass are the muntins. This is an awning window and its operator is on the bottom, resting on the sill.
We can also see the interior framing of the wall and the window. The wall studs are running vertically, butted against the window are the jack studs and next in line are the kingstuds. Under the window are the cripple studs, all the studs are sitting atop the bottom plate.
Batt insulation is used in between the wall studs and between the floor joists
Around the window we can see how the bricks are cut accordingly and it is evident that the window is in a preplanned location (as it always is)-every other row of bricks ends just at the window frame.
In this picture we can see that the top half of the building is farther along than the bottom half. In the top we can see the vents that are made in the brick for fans -most likely for a kitchen. Because brick expands there is an expansion joint created between the two brick sections. On the lower level roof we can see that there is roofing felt laid out as a vapor barrier and it is pulled over the edge a little bit to prevent the seepage of water below the roofing materials into the sheathing. On top of the lower level are stacks of either gypsum board or foam insulation ready to be installed.
The man in this picture is sanding down the foam that has been applied to the exterior in staggered blocks. On top of the foam will go layers of stucco for the finish.
This is an example of an awning window: as seen only the bottom portions open up, these windows are good for rain, they direct it down and away from the building.
This is a gable end that is not covered brick. We can see the finished soffit on the left and into the interior of the soffit on the right. We can see the rafters coming out from the roof. The side of the eave (horizontal edge of the roof) we see is the fascia. We can also see the flashing that is sitting atop of the rake (sloping edge of the roof), flashing is used as a water barrier. On top of the roof we can see the sheathing and on top of that the felt paper and shingles.
A bag of portland cement, a component of mortar and plaster.
This side of the building (gable) is finished on the exterior. We can see how all the different parts come together. The exterior brick is laid and the rough openings have the windows in them and the roof is framed aswell.
On this end of the building single hung windows are installed, only the bottomportion of the window slides up to allow for air circulation. The sash is the frame consisting of rails and stiles that hold the panes of glass together. The muntins are the pieces of the frame connecting the panes of glass. A top the window is the lintel, and below is the sill (directs water away from window) and between the 2 windows is the mullion.
On the roof we can see the peak where the ridge beam sits on the interior. From this view of the gable we see the rake which is the sloping side of the roof (eave -horizontal). Under the fascia -which is the horizontal strip under ther roof, the cornice is at the meeting of the roof and the wall, under the cornice is the frieze board which is the transition from the roof to the brick veneer. Under the peak the is a louvered window that is used as an air vent for the interior of the roof/attic.
The concrete blocks delievered prefab to the site ready to be put up on the exterior wall.
The concrete blocks that were seen in the stacks are being put up on the exterior wall -over the rigid insulation and the weather proofing. The concrete blocks are cut accordingly to creating the running bond that is seen. They are not butted up against the weatherproofing but rather there is a 2in gap between to create a drainage system inside the wall. The moist mortar can also be seen in between the concrete blocks.
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.
Type X gypsum board is 5/8 in thick, it is used as a method of fire resistance, and contributes to much of the fire resistance rating of a building. ASTM is incharge of conducting tests to determine the fire resistance of gypsum board. To get type X rating the wallboard has to achieve at least a one hour fire resistance rating
Type X wallboard is made with noncombustible fibers, they maintain the integrity of the core as the wallboard begins to shrink.

At this time there is also a fire sprinkler system installed -its going to effect the type of construction and the effects of building code and zoning laws.

There is a pile of bricks on the right hand side of the wall and it is unfinished, we can see the paving bricks ready to be laid, we can see the horizontal (courses) and vertical (wythes) already laid in the running bond style Description: This picture has two openings, they are both framed with trimer studs and a top plate. There are cripple studs all along the top and are finally interuppted by the header which is turned on its side. The openings themsemvse are framed with lumber all along the inner profile.
