This is an image from the exterior (it was getting dark outside) we can see the rough framed opening for the door, and the weatherproofing still around it. When I was talking to one of the managers he was saying that they are not gong to be able to finish the masonry work (The brick that is seen around the exterior) until it gets warmer because the mortar will freeze
This is a picture of the exterior, there are blocks of foam (not insulation, just foam) and they are being covered with a type of stucco, the joints between blocks are being grooved to make them look like blocks of concrete. Again this process cannot be finished until the weather warms up

This is a picture of a hallway on the first floor, it shows the installed gypsum board drywall and the screws before they are filled. On the right side we can see the joint where 2 pieces of vertical drywall meet (not horizontal like is recomended). There is no drywall tape or joint compound filled in at this point.
The manager of the construction showed me a room on the first floor that had all the electrical lines coming in from the entire building.
The wall on the right is a stucco finish and between the door there is a gap left -a joint to-be filled with caulk to allow for movement/expansion/contraction between two different materials
Here is an example of fire caulking joints, it provides a tight seal against fire, smoke, toxic fumes and moisture. It can be used on plastic, insulated and glass pipe, construction gaps, dynamic joints, HVAC ductwork and insulated cable.
The manager of the construction was telling me about a problem that they had with the fire safety requirements: The back of this opening (the blue area) was supposed to be covered in gypsum, but there was no way that they could put in a layer of gypsum (there is no space) so they had to talk to the inspectors and be creative. They put gypsum on both sides, and they are going to put the sheet of gypsum on top of that, in a way that it can be included as part of the other room. Then they will put the dry wall as planned on top of the studs facing the hallway as seen here.
elevators are car-framed with a platform. Here the elevators are framed using steel (on the left we can see the wood framing on the wall)


The fire extinguisher was by the doors to the exits (stairs) which were also by the elevators
A picture of the trusses above the fifth floor walls. Here we can see the horizontal bottom chords, nail plates are used for strong connections and also can be used for truss repairs, they are more economical and effficient then a series of nails. Metal framing is used a safety measure in case of a fire. And the very top we can see the sheathing of the roof
This picture shows the lateral supports of the truss, the webbing, top and bottom chords, held together y the nailing plates
In this hallway we can see the two walls of studs, the beam running between the walls and the ceiling that is being installed
An example of fire caulking, it creates a seal that is a barrier against fire, smoke, toxic fumes and moisture.

This is the framing of the bathroom in one of the apts. The rough opening for the door is visible, aswell as the jack stud, king stud, cripple studs, header, and top plate. The single hung window is also visible with the header and sill
This man is insulating the pipes that are installed in the ceiling, insulating water pipes can prevent heat loss and freezing. On top we see the rigid insulation, and the joints between the sheets that are sealed.
We can also see the section of a wall, the studs and the layer of drywall
This is a view of the hallway, it is fuly framed, it is waiting for the drywall. The manager i was talking to said that it took 20 guys a total of NINE days to frame this entire floor (pretty impressive, in comparison to the weeks it took 6 people to frame a small section)
This is the electricians panel , it is installed between the studs in the wall, in the back ground we ca n see the cripple studs and the wall studs
This hallway is covered in drywall, the walls are installed before the ceilings are installed. In the ceiling we can see the pipes, plumbing, and the sprinklers. The light bulbs are also installed (meaning the electrician has also been working) In the hallway is also a carpenter's table with a saw to cut materials as needed.
This floor is ready to be drywalled, the insulation is already put in the wall between the studs. The electricians have not installed the lights on this floor.

The man in the picture is using a caulking gun to seal the joints on the exterior.
The manager showed me the courtyard in the interior of the building, it was the roof of the first floor offices, and was open to the 3 floors of apartments. Running through the center was a walkway, there are going to be chairs and tables put in for the tenants.
The floor is covered in roofing felt and slopes down towards the drains. On the ground floor there are stacks of concrete blocks, they are going to be used to cover the ground, they are going to be placed level, to create a drain.
On the second floor (going to be offices) there are a stack of wood panels, they are goign to be the backing of the cabinetry that has not yet been installed on this floor.
This is the finsihed cabinetry in one of the apartments, the men working on this are waiting for the counter tops to be delivered
This is the interior of one of the apartments. The walls are finsihed, they are painted and we can see the single hung window is completly installed, theyre is also a crown molding nailed in at the top of the wall. The electricians have been in here, and we can see what will be a light switch.
This is an open area that is not yet finished, the floor is covered with roofing felt as weather/water protection. The walls are going to be covered in stucco. The white is the finish stucco -it cannot be finsihed because of the temperature drop, and the workers are waiting till it gets warmer to finish up around the site. The rough opening for the window is visible, as well as a layer of weather proofing that is pulled through to form a tight barrier
This is the interior of the stairwell, it is now filled with batt insulation between the rim joist, and the wall studs of both the 1st and 2nd floors
The men on the bottom floor are installing the handrail, they were talking about the wood blocking as I was coming up the stairs (the woodblocking between the studs is how the handrail is attatched to the wall.
Closer up we can see the balusters and posts supporting the handrail
This is the view of the interior hallways, the walls are fully insulated and soon the gypsum wallboard will be installed.

The interior of the second floor is still in progress, the floor is still concrete, the floor finish is going to be one of the final things to be installed. The electrical and mechanical wires are intalled and run through the spaces in the floor joists. We can also see the plumbing pipes.
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 a view from the interior of the 2nd floor, we can see the detail of the the floor trusses. The main trusses are running horizontally and the bridging trusses connecting the main trusses are running from front to back -they help spread the load of the structure. Above the trusses is the decking which runs continuously across the floor.
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.

The man in the back is applying the stucco finish to the piers, he is using a hawk and trowel. On the right side of the image we can see that he has not yet applied the stucco to the final pier, it just has the scratch and brown coats on
Batt insulation is used in between the wall studs and between the floor joists

This is an image from the stairwell, the electricians have installed the gas pipes, and these pipes will be hidden from view after the steel studs are covered. The block of wood is placed between the joists to allow for stability for the pipes.



On the interior of the building the workers were putting up a stucco finish. Here we can seethe gypsum lath of foam that is being put up over the rigid insulation.
Here we can see the different stages of the finish, on the right are the intermediate stages, and on the left is the finished coat. The bottom right corner are the water meters that have already been installed for what will be an apartment complex.
This picture shows the interior finish of the walls, there are two layers of a concrete/plaster mix that are laid before the finish coat of stucco is applied.Over the sanded gympum lath the plastic netting and scratch coat were applied, then the brown coat was applied, and for the finish the stucco was appliedThis is the closeup, the tight netting is visible, and the dinstinction between the intermediate and final layers of stucco is apparent.

This is the detail of 2 windows that have just been installed. The main frame is made up of the head (top piece), the sill (bottom) and the jambs (sides). The frame that hold together the panes of glass is made up of rails (horizontals) and verticals (stiles), between the windows is the mullion (which has not been filled in yet) above rests the lintel and below is the exterior sill which is sloped to direct water away from the window.
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 a window in a wall that has not been clad with the exterior brick. It's important to note the order of installation. After the weatherproofing goes up the windows are installed to maintain the air and water tightness. The frame of the window is make up of the horizontal members which are the jambs, the vertical at the top is the head and on the bottom is the sill. The frame that hold the panes of glass is made up the stiles (verticals) and the railes (horizontal) members. The intermediate pieces are called the mullions.
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.
