This paper describes a piece-based construction information system organized as a hypergraphic virtual environment on the World Wide Web. An array of cubes on the site's animated splash-page acts as a directory to a collection of data-theaters that give this information its virtual form. A mouse click on one of these cubes leads to an orthographic model of the object to be constructed. This model is an index to a database of scaled drawings, animations, and specifications. The index is hypergraphic because a click on the image of one of the pieces of the model leads to a data page that provides information about that piece in the context of its assembly. Panels surround the index to act as an interface to projections of the pieces of the object. These projections include elevations, plans, slices, and dimensioned details. A click on the elevation-panel leads to information on finishes, framing, and construction of each face of the object. From above, the plan-panel shows roofing, framing, floor plan, foundation layout, excavation, and utilities as an animation of the construction process. There are also animated slice-panels that cut through the object to give heights and materials. A click on one of these panels leads to two-dimensional drawings and details of the actual construction. The orthographic index morphs to a framed VR environment where the model can be turned and viewed in perspective. A click on one of the pieces of the model in this information the VR environment leads to specifications and manufacturing information about the materials of its construction. The user accesses this information through a tool-palette to communicate with design team members. In this way, the team can coordinate the document's development, review progress, and make changes to the information system. This breaks the notion of a construction document as an object-of-exchange and suggests the use of the computer as a medium of communication that facilitates the design and construction process. |
