Forms (rectangular pieces) are stripped along the perimeter of the western roof section, which is becoming a staging area for ventilation work on the existing building.
A closer view of the preparations for work on the ventilation ducts on the roof of the existing Science building. New ducts and pipes are seen at the right of the picture on top of the new roof.
Looking north, forms for the vaulted roof take shape. The rounded forms are now about half done, starting on the eastern side.
Looking downward from the crane, the top of the columns peaks through the beams that will extend along the vault.
Steel supports are placed to support the vault forms for the western roof of the Science library.
Looking south toward the courtyard, the newly-poured roof provides a staging area for the rebar for the vaulted roof.
Looking downward into the courtyard with the existing Science building beyond.
Looking from the crane tower toward the southeast, the roof of the third floor appears in the foreground and the base of the greenhouse appears in beyond
The third-floor roof extends to the north (below) and east (left) of the greenhouse, and low walls provide a base for the greenhouse area.
