Roof (Fourth Floor), Greenhouse, and Existing Roof

Roofing of the fourth floor areas started this week.

Roof (1)
The barrel-vault roof of the library, waiting for roofing materials.
Roof (2)
Looking westward along the roof of the third floor, with the greenhouse and existing roof above chemistry on the left.
Roof (3)
Looking from the headhouse roof to the northwest, the materials for the third-floor roof await installation. Work also progresses on the framing of the greenhouse.
Roof (4)
This picture is about 180 degrees reversed from the one on the left; the view is to the southeast, over the greenhouse framing, toward the head house.
Roof (5)
Looking southwest, over the new courtyard, toward the mechanical rooms and air handlers over the existing biology and chemistry areas.
Roof (6)
Looking southward over the courtyard toward mechanical areas above chemistry and physics. Some of the new exhaust units are particularly prominent on the roof.

Courtyard

A steam vault and cistern provide infrastructure within the new Science courtyard.

Courtyard (1)
Excavation on the east of the courtyard will provide a place for a cistern to collect rainwater for use in the greenhouse. A small scoop is used, so crane will be able to remove it from the courtyard area.
Courtyard (2)
Looking westward, the scoop is clearing room for the cistern on the east of the courtyard (bottom), while the steam vault (above) allows steam pipes to connect between the new construction and the existing Science building.

Transformer Area

Courtyard (3)
A close-up view of the steam pipe and water return leaving the new construction and entering the steam vault in the courtyard. Note the drain title/pipe along the new foundation — just below the window line (a window is just barely visible on the lower left).
Transformer Yard
A transformer enclosure is being updated to the east of the 1986 wing (Math/Stat/CS/Psych). This area, just south of the transformer area, supplies power to much of the Science building.

Second Floor

Second Floor (1)
This picture looks southward along the main path from Burling to the Student Center. Studs form a lab wall on the left, with the courtyard beyond. The masonry wall on the wall will be covered by brick, along a stairway down on the right.
Second Floor (2)
This area forms a storage and work area for one of the many types of pipe. Each type of pipe is color coded to indicate its purpose.
Second Floor (3)
Studding is stored in the library area. Note the tracks in the floor for compact library shelves that will be installed later.
Second Floor (4)
Studding is laid out along the floor on the northwestern part of the floor to indicate walls. Vertical studs then will connect the base and top studs laid along the floor and ceiling, respectively.
Second Floor (5)
Several floor areas are left open through the building for air conduits. This section shows return air ducts, ...
Second Floor (6)
while this picture shows hot/cold air supply ducts.
Second Floor (7)
Pipes for various services must run around the air handling ducts — generally creating an intricate planning puzzle.
Second Floor (8)
Air conduit curves along corridors, with pipes interspersed.

First Floor

For the most part, studs and many air ducts are in place on the first floor. Next, pipes are added through ceilings and walls. Also, conduit, particularly air ducts, are installed in the shafts that run between floors.

First Floor (1)
Looking down the main north-south corridor along the path that continues by the Forum to Burling. A stairway will go down to the right; light is entering the far end of the corridor from the western end of the new courtyard.
First Floor (2)
Rooms along the northern size of the building have been framed in, but few services are yet installed. This picture looks at the northwestern part of building along Eighth Avenue.
First Floor (3)
Again, the middle of the northern side along Eighth Avenue is framed, with few utilities.
First Floor (4)
The same pattern extends to the northeastern part of the building.
First Floor (5)
In contrast, a room in the southern part of the building serves as a center for pipe fittings and plumbing supplies.
First Floor (6)
Also along the main north-south stairway, a shaft area allows air handling ducts to move from the basement (below) through the first floor and onto the second.
First Floor (7)
Another view of the air shaft, looking downward. This picture shows pipes intermixed with the ventilation shafts.
First Floor (8)
A more distant view of an air shaft that extends between floors.
First Floor (9)
A closer view of the installation of ventilation of air ducts in the shafts, looking up from the first floor toward the second..
First Floor (10)
This picture shows something of the complexity of the arrangement of conduit and piping in these shafts from floor to floor.

Basement

In past photo collections for this project, views have progressed generally from north and west toward south and east. This set of pictures starts on the southeast, just north of the existing Psychology Department, then progresses north and west.

Basement (1)
This picture looks south along the eastern basement wall toward the existing Psychology Department. Wall framing has not yet started, and one can see the temporary, insulated sanitary sewer and storm pipes mounted along the far wall (on the outside wall of the current Psychology basement).
Basement (2)
A corridor opening has been cut into the current Psychology basement for future connection between the 1986 wing and the new construction.
Basement (3)
Framing is being installed for the labs north of the current Psychology Department. Note the same temporary, insulated sanitary and storm sewer lines along the far wall.
Basement (4)
Just a little west of the stud-installation area, studs identify offices and labs. This picture looks toward the courtyard area.
Basement (5)
Moving farther north, work focuses on installation of pipes and conduits. The main mechanical rooms lie along the northern part of the building, along Eighth Avenue. Many areas contain two-levels of pipe racks for pipes running in one direction; crossing pipes often run below (sometimes above) these main pipe trays.
Basement (6)
Relatively small pipes turn a corner from one corridor to another, with ventilation ducts above.
Basement (7)
A close up of one tower of values for a single pipe line.
Basement (8)
Electrical conduit carries power from main switch gear (shown here) to smaller panels found throughout the building.
