Clients often have difficulty in identifying and communicating their actual requirements to designers and vice versa. This is mainly due to the difficulty in comprehending the huge amount of information and knowledge with which the parties have to cope. In order to enable this immense magnitude of information to be addressed effectively to the client during the briefing process, this paper presents the data and process models for the development of the client‟s brief. The information is first modelled into structured data models using EXPRESS-G technique. The processes involved during the development of the brief is then modelled using IDEF0 technique. The developed models establish the foundation for the development of a prototype, which utilises an object oriented environment. The implemented object oriented data models then form the framework for the presentation of the client‟s brief. These models, when implemented into the computerised environment, would significantly enhance the communication channel between the project participants from a very early stage of a construction project. The outcome is not only an improved brief which fulfils the client‟s time, quality and budgetary constraints, but also one that narrows the gap between the client and the designer.
