Lean construction in railway platform construction

"For about three months, nothing worked at the Mühlburger Feld stop: The barrier-free conversion was pending. Now the stop is finished, so rail traffic can roll again - and three weeks earlier than planned." The schreibt KA-News about the construction site. Here we explain how Lean Construction has made this acceleration possible.

 

Data-driven process optimization with Digital Lean Construction

 

Our Customer Mature decided to implement Lean Construction in this project to make the construction process transparent and to enable collaborative process planning. We developed this planning in a joint workshop and evaluated and improved it in a subsequent weekly Lean meeting.

We approached the project with the Last Planner System from a bird's eye view and then worked out further details down to the day-by-day planning of the activities. Thus it was possible for us to fully understand the construction process and Software to visualize.

Step 1: Basic workshop

As an introduction to any project, it is of enormous importance to enable all project participants to apply lean methods. For this purpose, we have developed a special interactive workshop concept that teaches the employees all the necessary methods in a playful way. In addition, it also helps to understand the added value of Lean Construction and to apply it directly to the project.

Step 2: Overall process analysis

Following the basic workshop, we start analyzing the overall process together. In doing so, the project is broken down into individual process steps from back to front in order to identify all processes and dependencies.

Step 3: Milestone & Phase Plan

The overall process analysis is followed by the milestone and phase plan in which the entire project team breaks down the individual process steps into milestones, weekly work packages and a time line. This creates a transparent construction process that is far superior to the construction schedule in terms of detail.

Step 4: Weekly planning

We then go one level deeper into the project and plan all activities on a daily basis. This enables us to identify all interrelationships and potential problems in the construction process. In addition, the complete experience of all foremen flows into this process planning, so that the sequence can often be greatly optimized already in this phase. This was also the case in the Mühlburger Feld project.

Step 5: Evaluation & Optimization

The planning was evaluated and adjusted in weekly meetings lasting about one hour. This evaluation enables further optimisation of the construction process and shows how well we were able to assess our performance. Any disruptions to the construction process are identified directly in this meeting. The solutions often result directly from the discussion and are decided in detail in the subsequent construction meeting.

Step 6: Follow-up and key figures

With the help of the Lean Construction Software, we show that Lean is not only suitable for large projects, but can unfold its true potential in small, time-critical transport infrastructure projects, which are usually underestimated. It is precisely here that the generated data can be used for cross-project learning by creating project standards.
In addition, the evaluation of all process data in the system is possible. This allows meaningful key figures to be collected and further optimization potential to be uncovered. In particular, learning from project to project is promoted by a digital lean system.

Conclusion

The digital system and the location-independent access to data, allows new employees or project non-participants to visually immerse themselves in the project process of current or past projects in order to use the existing project experience.

Project Manager Jürgen Werner Says:

"Thanks to PLACE's consulting services, we were able to reduce the planned construction time together with the client. Thanks to digital process planning, the entire project team knows its tasks at all times. I and my team were particularly impressed by the transparency and the collaborative arrangements."

We would like to thank Reif for the trustful cooperation and are looking forward to the upcoming projects.
