Architectural design work depends on information created from the initial phase and this information has great influence on various parts of the design process. Despite this, the poor management and use of initial information still is one of the major problems in design. Design tools with planning information created in the initial phase do not address the need for data interoperability. This study aims to develop the Industry Foundation Classes (IFC) extension model for the management and use of planning information through integration of design models and planning information in design work. This paper introduces the scope, rationale, method, implementation, and verification of study. The validity of the proposed method is also demonstrated.
