ABSTRACT
This chapter focuses on an ongoing study designed to support heritage clients in making informed and sound decisions in defining their requirements. It investigates the development of an ontology-based, Building Information Modelling (BIM)-enabled framework for Employer Information Requirements (EIR). Ontology will facilitate the sharing of knowledge and understanding between relevant parties by defining domain terminologies, vocabularies and relationships in the same way for all stakeholders. Research work in the field of requirements advocated construction briefing as client requirements process within the discipline of concurrent engineering for life cycle design and construction. OntEIR saves time in specifying requirements for projects and gives excellent results in terms of quality and consistency. Another model that has been implemented in this area is the Client Requirements Processing Model (CRPM), which adopts structured methods in translating the voice of the client into the voice of the designer.
