Abstract:
The thesis examines the integration of lean construction principles in tunnelling using the example of the Strömmen Passage, a section of the Anneberg-Skanstull Tunnel. The tunnel, which is intended to meet Stockholm's increasing demand for electricity, runs under urban areas and crosses Strömmen, a basin in the Baltic Sea. A comprehensive data analysis identified the biggest problems in conventional tunnelling in the areas of machinery, personnel management, logistics and time management. The analysis serves as a basis for evaluating the potential of lean methods such as the Last Planner System, Kanban, Just-in-Time, Andon, 5S and Total Productive Maintenance (TPM). TPM and preventive maintenance strategies in particular could reduce machine downtimes and increase machine availability. The optimisation of material logistics through just-in-time and Kanban could also reduce storage costs and improve the material flow. The work develops key performance indicators (KPIs) to monitor and continuously improve the performance of lean methods. In addition, feedback mechanisms are introduced to ensure sustainable implementation. Finally, a comprehensive concept for the application of lean construction in tunnelling is presented. This concept recommends the gradual implementation of lean methods in order to increase acceptance and overcome resistance. The integration of lean principles as early as the planning phase is recommended in order to establish efficient work processes and improve project results. In summary, the work shows that lean construction principles in tunnelling offer significant benefits, including increased efficiency, reduced costs and improved construction quality. These findings form a basis for further research and development in the field of lean construction in tunnelling.
