Architectural design is interdisciplinary team work within the context of architecture and engineering fields. Today, the information inputs from various disciplines and experts are needed in the design of buildings which have large areas, different technological systems and complicated functions. The data transfer procedure between architects, engineers and various disciplinarian experts has been modified due to commence of performing the architectural-engineering design process in the digital environments. Engineering fields which could engage to design process only after a preliminary architectural design phase in the traditional design period; can take their place simultaneously with the architects at the beginning of the design today without restricted by the time and place by means of speed and easy communication abilities of the digital technologies. The first aim of this work is to research utilization rate and methods of the digital-synchronized design abilities in today's architectural offices which are used among the interdisciplinary relations such as architecture, engineering, landscape and interior architecture. In this work, a questionnaire work has been applied to the hundred architectural offices in Ankara. What kinds of effects concerning in the utilization of computer-network technologies in the internal office works and inter-disciplinary relations have been revealed. Depending on the obtained data, methods and standarts have been recommended in order to use computer technologies productive in the architectural design and interdisciplinary relations.
