This thesis examines the application of the lean construction approach in the development of an operational construction plan. The theoretical part presents the development of lean production and lean construction, its fundamental principles, and the most common types of waste in construction processes. Particular attention is given to the Last Planner System and takt planning as approaches for improving planning reliability, coordinating construction teams, and ensuring a more stable workflow. The practical part examines the Litijska–Pesarska residential development project in Ljubljana, with a detailed analysis focusing on drywall works in Building C. The starting point is the existing schedule, prepared using the Critical Path Method, in which the drywall works are presented as a single activity lasting 50 working days. Based on the project documentation and the existing schedule, an alternative proposal for organizing the works according to lean planning principles is developed. The building is divided into takt zones, with work packages, construction teams, activity sequences, and takt time defined. The takt plan is developed using the Hoylu software tool. A comparison of the two approaches shows that lean planning provides a more detailed spatial and temporal representation of the construction process, clearer coordination of construction teams, and better monitoring of work readiness and progress. The proposed approach complements conventional scheduling, while its successful implementation requires collaboration among project participants, continuous removal of constraints, and adaptation to actual site conditions.
