Electronic product catalogues and brochures are gaining
popularity but there is little agreement on content, format and
searching methods. This limits their usability and integration with
existing construction software tools. This paper examines a productmodelling
approach to delivering building product information and
describes a proposed multi-tier client-server environment. ISO/STEP
and IAI/IFC building product models are considered to facilitate
representation, exchange and sharing of product information. The
proposed architecture incorporates scalability with middleware
components that would provide single or few points of entry to
integrated product information. This paper is part of a research
project, which builds on the results of related projects including
ConstructIT Strategy, PROCAT-GEN, Active Catalog, COMBINE and ARROW,
towards implementing the required software components
