This paper describes an information model for client requirements processing in construction. It derives from a process 
 model for client requirements processing which was developed in response to the need for an appropriate tool to define, analyze and translate, within an integrated framework for concurrent life-cycle design and construction, the explicit and implicit wishes of clients into solution-neutral design specifications. Client requirements processing is one of the design stages in concurrent life-cycle design and construction, a conceptual framework that was developed for the implementation of concurrent engineering in construction. The model described in this paper, provides a formal representation of
 the nature, sources and interrelationships between information required for the implementation of the process model in a computer environment. The model is described using the EXPRESS-G, a graphical notation for the display of information models in the EXPRESS language, but which can be used as a modelling technology in its own right. The rationale and details of the process model which forms the basis for the information model are reviewed, and the schema and entity levels of the EXPRESS-G model are presented and discussed. The provision of a framework for implementing the process model in a computer environment, will enhance the processing of client requirements. This in turn will facilitate the implementation of concurrent engineering and the realisation of its benefits in construction.
