A Lean Design Management Process Based on Planning the Level of Detail in BIM-Based Design

Abstract

Few construction companies apply the available lean tools and processes in an integrated manner when managing design. Additionally, various lean design management -tools and -processes have each their own strengths and optimal phases in project when to apply them. Earlier approaches in lean design management have not explicitly included level of detail of BIM-models in connection with planning methods in an appropriate manner. For example, the Last Planner System (LPS) is a planning and control system that uses collaborative social methods to get task dependencies and commitments from project stakeholders, but it does not provide any guidance what those tasks should be in a BIM-based process. On the other hand, location-based methods such as Location-based Management System and takt planning have provided guidance for scheduling production by using (LPS). Thus, by combining information from various sources we were able to define a location-based design management process using the concept of level of detail that can be integrated with LPS. The level of detail definition must start from the end-user of the information in each stage of the construction project. The model was co-created and validated in focus group meetings with design and construction companies. In future research we will run case-studies to test the model in real-life settings.
