Enabling lean design management: An LOD based framework

Abstract

Question: How can we use the Level of Development (LOD) concept to better develop BIM models under a Transformation, Flow and Value (TFV) perspective? Purpose: The purpose of this study is to introduce a new LOD framework to relate the LOD value of a model element to its actual design context and to manage the design process according to the TFV theory. Research Method: Review and analyze current LOD definitions and guidelines. Develop a new LOD framework and align its use to lean design management. Findings: The new framework enables the application of lean design principles through a practical use of the TFV theory. The defined LOD variables, the LOD matrix, and the parametric nature of BIM models facilitate the integration of the TFV theory into the management of design workflow on BIM projects. Limitations: The LOD framework needs to be applied experimentally to investigate its full potential. Implications: The paper builds on the LOD and TFV theories. Researchers can employ current findings to develop new design management procedures and tools to ameliorate the quality of the design process as well as the final design product. Value for practitioners: This study provides practitioners with a systematic and flexible procedure to define and manage LOD requirements inside BIM models. It also enables them to integrate lean design principles into the project’s workflows. © 2016, Lean Construction Institute. All Rights Reserved.
