Lean Construction has been developing in France since the 2010s, mainly under the impetus of specialized consultants for the largest general contractors.
‘Takt time’ is a term used in manufacturing to describe pacing work to match the customer’s demand rate. ‘Work structuring’ is the practice of scheduling out work and is a part of designing a production system. Takt time planning then, is one method for work structuring around a set pace of work.
As a foreword to the post, I think there are many ways one can execute Takt time planning (TTP). The fact that there isn’t much research on the topic in construction means that it is definitely an open question. Through some iteration and research, the five step method below is the best practice to Takt time planning so far.
In recent years, Takt Production has received a lot of interest in the construction and we are seeing more and more implementations around the industry. Takt Production comes from the aeronautical industry and its purpose is to stabilize and maintain rhythm of production.
Location-based scheduling methods are not new. In some countries such as Finland, the adoption of line of balance schedules is widespread and used for decades. However, in the United States these schedules have remained unpopular.
Takt time planning is a great tool for aligning crews and creating flow on site. However, it’s still just a plan and it will inevitably fail at some point. One of the reasons for using takt time is not only to create flow, but also help pinpoint where the bottleneck is on site.

The Location-based Management System (LBMS) builds on decades of work on location-based scheduling methods. The first recorded utilization of location-based methods in vertical construction was in the Empire State Building.
In my previous post about LBMS, I mentioned that cascading delays can cause project duration increases of 10% or more. This blog article digs a bit deeper and explains what cascading delays are, why they happen in construction projects and how LBMS controlling can help to prevent them.
Takt planning has come into its own in the last few years. Takt is German word (Taktzeit Cycle) for establishing the “beat” or rhythm of a process. Companies including BMW, Sutter Health, and others have reported very positive results of implementing Takt planning.
The Last Planner System (LPS) is a production planning and control system designed to produce predictable workflow and rapid learning in programming, design, construction and commissioning of projects. LPS has five main elements.
Modern understanding of lean has evolved over several decades and is mostly based on the knowledge gained from the past experiences. However, in today's world new knowledge and developments are evolving very fast, which means that our today's ingrained understanding can tomorrow already be old.
