Successful medical planning constitutes the basis of a successful design and is considered a critical element in the process of hospital design. Medical concept drawings are a graphic scaled presentation representing the general planning concept of the proposed hospital. They incorporate a comprehensive study in terms of optimum traffic flow, location of departmental zones, departmental circulation, inter- and intradepartmental relationship, flow of patients and outpatients, and other planning issues relevant for this stage. Medical concept drawings are further developed and detailed into medical Schematic Drawings, which show the internal configuration of each department according to international standards. They are coordinated with all engineering disciplines, to achieve a comprehensive design package.
