The Pour is a study of the construction process of Williamsburg’s Public Library. The Library is designed through an architecture of ‘shelves’ - as books exist on shelves, they are picked up, read, and placed back. A shelf supports and shares its stories with the visiting reader. The architecture of Williamsburg’s Public Library seeks to shelve the life of the public, and in turn be read - observed, interpreted and used. The technical study attempts to explore an architecture that is built with a bespoke system of casting. It questions the nature of in-situ fabrication and the role of materials post-production. How can the construction process be left behind as a story - an integral part of the building’s character? The dissertation is interested in the dissection of this character - where perhaps certain elements of the library are lost in time - without function yet remnants determining space around them - much like the existing shell of the Domino Sugar Refinery and its position amongst the library. The exploration will be directly involved with making these ‘shelf ’ structures at certain scales, constantly testing and speculating with the potential of the casting system. How can moulds of formwork be set up, released and left behind? Aside from an interest in their fabrication, the ‘shelves’ will be explored functionally as a structural system that supports both the exterior wall of the Domino Sugar Refinery and the attached public programs; as well as the moderator of the atmospheric conditions necessary to support different public environments.
