In recent years takt time planning has been a more and more utilized method in construction projects. In 2010 the Norwegian contractor Veidekke started their first takt project and have since carried out several projects with the method. The results of these has been wavering from breakdowns of the takt system to great success. It is therefore interesting to see how takt is used by different companies internationally and which experiences these have compared to Veidekke. Through literature reviews, interviews and case studies the paper looks at takt as practiced by Porsche Consulting, The Boldt Company and Veidekke. Their practical applications have a lot in common, but are distinguished – among other things – by the way to involve subcontractors, the types of projects that they use takt on, and how they divide the project into zones. Currently, takt seems to be dependent on key persons familiar with the method, and there is a need for a guideline for takt so more projects can benefit from use of the method.
