I N T R O D U C T I O N T O T h e B U I L D I N G The Geisel Library The development of the central library of the university of california in san diego was the product of an intensive interchange of ideas among the library staff and the office of architects and engineers from William L. periera & associates. Geisel library is a biomedical library which is centrally located within the other three cluster of colleges, combining undergraduate and science library facilities. The design of the library is as such that it was aimed to reach beyond the library’s practical capiblility as a functional building. It was designed to be able to convey to future generations the idea of power and permanency of the knowledge contained inside it. The community behind the project envisioned a complex of libraries serving the needs of both the campus and the general community. those envisions included a biomedical library as an integral part of the school of medicine, The library that was already in operation at the Scripps institution of Oceanography, Three cluster libraries each centrally located within the other three surrounding colleges and the central library of the university which includes both the graduate humanities and social science collection. 2

Where it all began.

Like all great projects, there was a time where designers had to start from scratch. Before schematic designs were begun, the architects studied and reviewed all the background material avaliable. in order to aid the process, criterias are developed in order to evluate schematic designs before they are being pursued. The architects finally agree upon the importance of a tower to be integrated into the design. however, upon survey amongst librarians, it was agreed that the tower form is not desirable unless the floors themselves are large. Hence, the cube or box form was explored. although a cube or box form fits the criterias of an effectively functional library, the cube by its geometry alone does not establish a significant form from an architectur- al standpoint. It was also known that the floors from a cube schematic may be too large for comfort. A modification of the cube style was then explored. the central court scheme turns inward to a multi storied, sky lit court with stairs and elevators at each floors. Upon discovering and understanding the requirements for the project, four schemes emerged. each of which afforded a solution to the problems and in one way or another helped contribute to the ultimate design of the central university library. 3 T H E S C H E M A T I C P H A S E The Multi-Tower Scheme The Subterranean Scheme The Gateway Scheme The Compound Scheme

The Refinement.

Initially, due to the long cantilever employed in the design, a steel frame was thought to be the most economical method of construction. The proposed system utilized four huge steel trusses, a full storey in height that were concealed in the second floor of the spheroid and created a platform for a standard structual framing on the third fourth and fifth levels of the spheroid. Despite being given the green light to proceed with the construction of the project via steel as the mainframe, prices per ton of steel were skyrocketing back then. Due to this occurence, a building that was framed in concrete up to the second level of the spheroid was proposed. however the second scheme had negative aspects mainly due to the fact that the previous scheme was highly dependant on steel truss. This truss constituted an interior planning problem and severly limits the flexibility of floor floor planning. Seeing that the fusion of the two materials is quite costly, a third and final scheme was made using only reinforced concrete. This scheme moves the cantilevering action of the steel truss from the inside of the building to the exterior in the form of sixteen diagonal concrete members that tie each of the three lower floors of the sphere together. The all-concrete system provides a new dimension and vocabulary in design.

Lower Level (1st Floor)

Staff and public area dictate the main use of this level of the library. There is a significant amount of space on this level dedicated to mechinacal rooms where thermal energy are housed in an underground tunnel that would enter the building at this level from the southern face of the building. 6 T h e l i b r a r y l e v e l s Viewing^ Media Stations Tunnel Computer Lab (PCs only) Copier WEST SOUTH NORTH Access to all floors Older Journals^ Arts Books & Call number N, SB, TR Quick-Use Computers Books & ScoresMusic Call number M 1st Floor WestComputer (PCs & Macs)Lab Tables &Carrels Brody CollaborativeStudy Space To floors 1&2 only Tables Scanner Copier Printer Carrels Geisel Library 1st/Lower Level Geisel Library floor plans.^ Click here to access all Rms 1040-1045Group Study E E = Emergency Exit E E E E E Printer Last revised K.

Second Level of Stacks (5th Floor)

The second level of stacks is approximately 46 meters across. It contains a major portion of the book collection. Major lounge areas are present in each of the four corners of this level. Patrons seated in these areas will have a spectacular view of the vegetation outside and will be protected from the sun by the overhanging floor above.

Third Level of Stacks (6th Floor)

Third level of the library is the largest floor, spanning 60 meters in diameter. This floor has the major part of the book collection and has the largest number of individual reader stations. The stacks that radiate out from the center of the floor creates niches of private spaces for reading.

Fourth Level of Stacks (7th Floor)

This level of stacks is identical in size and shape to the second level of stacks. The difference between the two is that the fourth level is surrounded by the roof area of the floor below hence providing the opportunity for the roof area to be developed as an outside study area

Fifth Level of Stacks (8th Floor)

The top level of the building contains the special collection and rare book collection. it is the only floor in the building that has controlled access.

C o n s t r u c t i o n M e t h o d In order to grasp the exact the exact method of forming the quality of concrete desired by and acceptable by both the architect and the owner, a half-scale model of a portion of the concrete bents was made to demonstrate the architect’s vision. 11 Test Model of Concrete Bent The lower two floors of the building were built first, so that the forum level could be used as a platform for the scaffolding that would hold the form work in place. The scaffolding would remain in place until the completion of the top floor. This was necessary because the post tensioning of the lower floors of the sphere would not be accurately executed until the floors above were exerting their maximum load.

Where we all began.

Upon being given this building as part of our assignment to better understand the process of building construction, we were intrigued as to how the sixteen concrete bents function in terms of support and the importance of these bents during the construction process of the library. Our first clue as to what Geisel library is all about derived from the classification that our assigned building is classified under solid construction as opposed to the other class which is surface construction.

Initial Attempt.

our initial attempt at breaking down this project to further understand the construction process was to introduce a diagonal section cut across the building. This however does not portray the elements of the structual support effectively and our final section cut was then revised.

Finalized Decision.

After discussing where the best area to create a section cut for the model would be, we finally decided to insert the section cut along one of the concrete bents in order to demonstrate how reinforced concrete is like with our model.

Getting There.

After finishing all the required cutouts to create our model, we could slowly start to see how the concrete bent structure is holding out each floor slab. Images were always used as a reference during modelling

More Trials.

Due to our decision to utilize cardboard to create the form instead of casting it, we had to conduct more trials to see how applying a layer of plaster would react towards cardboard. Trials concluded that a single layer of plaster by itself would be subjected to cracks. our discovery was that pva would help us achieve what we envisioned.

Moment Of Truth.

Scrape & Spray.

Due to uneven coating during our plaster application process, we discovered that by scraping off the excess amounts on the surface of our cutouts, it further enhances the concrete texture emulation we are trying to achieve.
