Ultimately comprehensive
and resounding results


Refine translates the terms Lean Construction and change into a language that everyone understands. So that this always succeeds in a goal-oriented manner, we think and act according to the Lean methods that we have refined and call "bottom-up and face-to-face". Empathy, simple concepts, comprehensive knowledge and technical know-how are combined as never before to produce a result that is convincing in all areas of complex design and construction processes.

Know-how now

The integration of lean thinking into one's own company is also a pedagogical challenge. Therefore, the simplicity of the method used is the key to a perfect process execution. In our workshop series entitled Refinery, we explain how construction processes can be designed effectively and efficiently with the help of the principles of lean. During the one-day workshop, our experienced construction engineers will introduce you to lean principles and instruct you to integrate them directly into your own projects.

In the Refinery all participants learn the following aspects of Lean Construction:

  • What is Lean Construction?
  • Lean Principles
  • Types of waste in construction indusrty
  • The methodology of the Last Planner System
  • Short-cycled detailed production planning for the planning and execution phase

People are interested in people

We play in every league, whether in a small or large team, both nationally and internationally.

The term Refine stands for improving, grading up and changing. Our network approach is not described by the common loose association of partners; rather, it works with the resounding power of a strategic segmentation into cells. This not only guarantees work performance that is constantly self-optimising, it also guarantees the reliable availability of personnel.


We value the messenger as much as the message

Our employees are what distinguishes our company – extensive experience and the best qualifications combined with motivation and enthusiasm for the goal.

Dr. Claus Nesensohn

The future of construction relies on the harmonic collaboration of all process participants and a coordinated Lean System.

Starting out as a carpenter and civil engineer, my path led to a PhD degree. My consultancy work encompasses national and international projects of every size. As founder and board member of Refine, I bring the causality of all process developments in the trade sections and decision-making hierarchies together and make sure that Lean leads to the success that our clients desire.

Intelligent building demands new thinking.

After graduating in Building Technology and Real Estate Management in Stuttgart and after studying for one semester in Great Britain, it quickly became clear what really drives me. Lean Construction, Lean design and the Last Planner® System are the future of construction. As an experienced consultant at Refine, I have the daily opportunity to make a difference and spur new thoughts and work processes for continuous improvement.

Harmonising project teams means avoiding waste.

Since 2006, as a trained carpenter, I recognized the considerable potential for optimization in the construction industry. The key to realizing this potential was discovered during my studies as an industrial engineer (M.Sc.) in the context of lean philosophy. Since then, I have been firmly convinced that the greatest barrier to success is the lack of or incomplete harmonization of project teams, which can be achieved through the practice of lean philosophy. As a consultant at Refine Projects AG, I am now not only able to continue the journey I started in 2006, but also to share my enthusiasm.

How can the new be brought into the construction world?

As a researcher, author, editor, and consultant, I am convinced that the construction industry must change in a lasting way; a transformation from the current conflict culture to a collaborative approach. After studying industrial engineering in Dresden and studying abroad for two semesters in Auckland, and conducting research work at the University of California in Berkeley and at the Pontifical Catholic University in Santiago, Chile, as well as my continuing research activities, I am aware of the importance and effectivity of carrying out a project in a team-oriented way.

Bülent Yildiz

From semi-conductor production to a new hotel building - all these areas have one thing in common:

Only those who meet the challenges of complex design and construction processes and understand them as an opportunity for change, set a sustainable process in motion within projects that is nothing less than the future form of work. As lecturer, founder and member of the board at Refine, with many years of experience in the management of national and international projects in all sectors of the industry, I develop Lean-based production systems with our clients for optimum added value and target-aimed collaboration.

With our enterprise, Refine, we have created the opportunity to position the excellence of our team optimally in the market and at the same time give our activities a mission: Face-to-Face Lean Solutions.

Dr. Ing. René Huppertz

Change needs trust

During my studies in civil engineering at RWTH Aachen University, I realized that in addition to the technical challenges, economic and socio-cultural aspects in particular decide on the success or failure of projects. For this reason, I supplemented the study of Civil Engineering (M.Sc.) with that of Economics (M.Sc.) and combined the findings of both disciplines in a - still ongoing - PhD.

From my point of view, the quality of the relationship, the trust among the project participants, motivation and appreciation for all construction projects can be seen as crucial success factors. Since these are both part of the Lean philosophy and the Refine culture, I'm sure we can revolutionize tomorrow's construction industry together.

Mark Novinsky

Excellence is created when knowledge meets Team

Through my studies at the KIT (Karlsruhe Institute of Technology) I have the excellent theoretical knowledge, which characterizes the German construction industry. Due to civil engineering internships in Germany and Romania and a semester abroad in Argentina, I realized that you have to share the experience gained and the knowledge acquired in order to be successful in the team. As a consultant of Refine I now use the opportunity to share my knowledge purposefully, further develop and establish lean thinking worldwide. With the best approaches, the most interesting customers and our innovations, we help to take HP to the street.
