Lean construction in platform construction

"For about three months nothing worked at the Mühlburger Feld stop, because: The barrier-free reconstruction was pending. Now the stop is finished, so rail traffic can roll again - three weeks earlier than planned. The swrites KA-News about the construction site. How Lean Construction has made this acceleration possible is explained here.

 

Data-driven process optimization with Digital Lean Construction

 

Our Customer Reif 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.

Thereby we approached the project with the Last Planner System from a bird's-eye view and then worked out further details except for the daily planning of activities. Thus it was possible for us to fully understand the construction process and to work in our Software to visualize.

Step 1: Basic workshop

As an introduction to every 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 employees all the necessary methods in a playful way. It also helps them to understand the added value of lean construction and apply it directly to the project.

Step 2: Overall process analysis

Following the basic workshop, we start together with the analysis of the overall process. 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 & phase plan in which the entire project team breaks down the individual process steps into milestones, weekly work packages and a timeline. This already results in a transparent construction process, which is far superior to the construction schedule in terms of detail.

Step 4: Weekly planning

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

Step 5: Evaluation & Optimization

The planning was evaluated and adjusted in weekly meetings of about one hour duration. This evaluation allows further optimisation of the construction process and shows how well we were able to assess our performance. Any disruptions to the construction process are directly identified 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 that it can unfold its true potential especially 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, it is possible to evaluate all process data in the system. This allows meaningful key figures to be collected and further optimization potential to be uncovered. Especially the learning from project to project is supported by a digital lean system.

Conclusion

The digital system and the location-independent access to data enables new employees or those not involved in the project to visually immerse themselves in the project flow of current or past projects in order to use the existing project experience.

Project manager Jürgen Werner says:

"By consulting PLACE we were able to reduce the planned construction time together with the AG. 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 joint arrangements".

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