This paper is the counterpart to the paper Collaborative Takt Time Planning of Non-Repetitive Work of Iris Tommelein. Both paper describe Takt approaches in two different geographical and project contexts. A follow up paper is planned and will compare the described approaches and assesses their applicability and success. This Paper describes the German Takt approach, called Technical Takt Planning and Takt Control. The authors used this method in on several projects in construction. It describes the historically development of Takt in construction in German and leads to the current state of the theoretical method used at the Karlsruhe Institute of Technology (KIT). The third part of the paper gives a practical example of the KIT approach.The contribution of this paper is that it offers a characterization of the Takt approach that is used in Germany in several construction projects. The researchers try to give with the KIT Method an overview in science for the German Takt Planning and Takt Control approach. The method is for Takt integration in make to order production.

Mastering complexity in Takt planning and Takt control -Using the three level model to increase efficiency and performance in construction projects." In: Proc. ABSTRACTWhen scheduling a construction project, resource consumption, efficiency of the trades, external influences and the possible changes within the construction process must be taken into account. Hence, the complexity of the construction schedule and an exact planning is difficult. So often the time buffers are balancing the unexpected events. That's the reason the full potentials of the construction project are often missed. The approach of Takt Planning and Takt Control (TPTC) offers a possibility to dimension buffers and schedule them transparently. This approach is often seen as a rigid and complicated procedure. The planning has to be adapted with a huge effort to changes in the construction process and therefore often does not show the real image of the construction site. The three-level model tries to structure the method for all participants. This paper aims to improve the simplicity of dimensioning value, time and activities in Takt Planning. Performance indicators can provide information about the dimensioning and its adaptation to the construction process. Thus, TPTC can be seen as a flexible method for controlling the complexity of construction planning and excellerate efficiency of the hole project.

Takt Planning and Takt Control (TPTC), as a method of Lean Construction, has been developed over years and has increasing applications in construction practice over the last years. The collective understanding is that this method can only be implemented when there is a high level of repetition in the structure of a building project and in fact it is frequently used in such kind of projects.A case study shows how this method was implemented on a construction site with no obvious repetition in the structure. Takt Time was reduced to a level of one hour and the single room construction site was split into small areas. A high collaborative approach of the TPTC was used. The completion time was reduced from over ten days to three days. This paper documents the steps of the implementation, the integration of the team and subcontractors and also compares the typical approach before the optimization with the results after the Takt Time integration.

Takt Planning and Takt Control (TPTC) as a method for construction has the potential to reduce construction time in relation to normal scheduling without the increase of manpower. This leads to the question: what changes with the use of Takt planning? One theory is that Takt planning is using buffers more effectively than other schedule and planning methods. This paper provides an overview of the various buffers in Takt planning and describes how they can be used.
