Short takt time in construction - A practical study

Abstract

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.
