These pictures show interior construction within the new part of the Science Building. Many thanks to Paul Slycord and Weitz Corporation for supplying these pictures!

| Roof (Fourth Floor) | Greenhouse | Third Floor | Existing Roof | Second Floor | First Floor | Basement |
 The roof of the new building, looking east with the arched library roof at the left. |  Looking toward the northeast over the new roof toward the new north dorms. | |
 Looking northward along the roof toward the Campus Center. |  Looking southward along much of the new roof, over the 1986 building. |
Work on the greenhouse focuses upon waterproofing of the floor. This proceeds in several steps:
After the first main layer of waterproofing (step 3), 2 inches of water are poured throughout the region and let set to check for leaks.
 Fabric is being unfolded and laid in the room area to the upper left of the picture. Tar is applied on top of the plastic (lower left). The complete first layer (with tar) is shown on the room areas on the right. |  Fabric is unfolded (at right), and some tar has been laid. | |
 A distance view shows the base of several room areas. Tar has been applied over fabric in two rooms on the right plus one near the left. A workman is starting the application of tar over the white fabric. |  Applying the tar layer over the fabric sheeting | |
 Two room areas with the first tar layer completed |  A closer view of a room area with tar layer (with a drain in the middle) |
 Since work is progressing from the lower floors upwards, much of the third floor serves as storage. |  Drain points are being installed in the northeastern part of the third floor. |
Work on the existing roof of the Science building includes:
Eventually, much of the existing roof will be replaced.
 Installing of new conduit in the area over the current Science Division Office. |  Installing part of a new roof and building curbs for equipment |
 Looking westward from the middle of the floor. |  Looking southward toward the courtyard | |
 Much of the second floor, looking toward the southeast and the existing Math/CS/Psychology wing. |  Looking eastward through the library area, the red electrical extension cord catches one's eye. Note also the tracks in the floor (right) which will allow the use of compact shelving in the library. | |
 Looking toward the northwestern corner of the area. Trivia Question: How can one tell this is the northwestern section, rather than a view toward the courtyard? |
As with the second floor, these pictures progress counterclockwise, starting from the middle of the first floor and looking west.
 Looking west along the main central corridor toward the north of the existing building (near Clark Lindgren's lab and the growth chambers). |  An air shaft will run up along the north side of the current Biology lab areas. This space is being filled with studding, in preparation for sheet rock that will finish the air shaft wall. | |
 The corridor to the west of the courtyard has the first parts of air ducting in the ceiling. |  Studding is in place along corridors and under the windows near the courtyard. | |
 Installation of air ducts |  An electrical breaker box resides in the middle of studding for several rooms. | |
 Looking down the hallway to the east of the courtyard toward the existing building. (The old driveway entrance between Psychology and Physics would be at the end.) |  Looking at the southeastern part of building; the far opening is between the Chiller Plant on the left and the existing Science Building on the right. | |
 Looking eastward toward the Chiller Plant |  Looking from the southeastern section toward the northern middle of the building (under the Library) |
 A corridor in the hall separates a large mechanical space (left) from labs (right). |  A section of the mechanical rooms and air handler units |
