One of the newest developments in building is the application of systems analysis to design and construction. The systems approach depends heavily on the use of prefabricated components and modular subsystems, in both design and construction processes. Construction times are shortened and costs often lowered because the flexibility of prefabricated subsystems allows construction on the building shell to proceed while interior design is still in the planning stage. The use of performance specifications provides additional control over construction costs and saves additional time by using products that have already been tested and used successfully. This report focuses on the experience of one architectural engineering firm that uses systems analysis as one approach to the design and construction of school facilities.
