Preliminary models for the computer-aided building design and construction management process

This research project deals with computer- aided building design and with the development of a preliminary systems model for a national computer-aided design process. The purpose is to introduce a design system into common use within 5 to 10 years which is more advanced than today and meets requirements of different parties involved in construction. This research report covers the construction project as a whole from preliminary project planning to the use and maintenance of the finished building. The main stress is laid, however, on the development of a design process model. In the prestudy, on which this report is based, preliminary models were created. In the study, different phases of the construction project and application of information technology to these phases are discussed. The development needs of the construction project from the client's point of view together with a preliminary model for the control of the construction project are also presented. The building design process becomes essentially different when changing from manual design to CAD. This change is described both in writing and by means of a diagram. The implementation of information technology in different phases of the design process is described separately.
