Continuous and robust process planning is contrary to the different goals of project participants in the construction business. The aim of holistic building process management must be to optimize the overall process by streamlining individual processes. Lean management methods are increasingly being used to harmonize building processes. For this purpose, especially the method of takt time planning and takt control is appropriate. Building information modeling (BIM) is another promising way to promote a collaborative planning and construction process. BIM is generally understood as a virtual 3D model of a project with additional information. In order to be able to use the synergies of the two methods, the requirements, framework conditions, and goals of the two methods must be coordinated so that the added value of information for process planning can be used. The parallel application of lean construction methods and BIM can create added value that leads to productivity gains. In established BIM applications, the product (e.g., building) is planned as optimally as possible. However, the production process is not sufficiently considered. This is where lean construction methods are used to optimize the process. This article describes synergies through the combination of both methods and defines the requirements for a new BIM use case, "takt time planning and takt control." The presented concept is prototypically tested on a hotel tower project and the benefits and requirements are discussed.
