This examination paper has been commissioned by the Tunnel and Bridge unit of Ramböll in Stockholm. The purpose of the report is to describe the procedure of constructing a calculation template in Excel for the designing of a retaining wall, based on the principles of Lean design. The intention of making processes more efficient in order to save time and improve quality exists within most businesses. In management literature, one reappearing tool for making processes more efficient in the construction consulting industry is called Lean design. Lean design can be applied to all design and calculation processes for different types of bridges and structures. This report describes the background to Lean design and the process of trying to implement its principles in the making of a calculation template for the designing of a retaining wall. The purpose is to enable a more efficient designing process, where calculations are standardized, and the results of the process are comprehensibly presented to other actors within the consulting business, such as reviewers and CAD designers. The template is to be used for designing retaining walls in different situations depending on, for instance, construction and soil material, geometry and loads. Consequently, a major part of this report has been devoted to standardizing calculations for load effects and bearing capacity in the construction, depending on different possible settings. Designing is regulated by Eurocodes and national annexes, why it is important to refer to relevant chapters in the regulations. The regulations depend on settings and the field of application for the construction. Therefore, some generalizations of the design process have been made. However, during the process it has been clear that implementation of Lean design is one possible way of making construction design more efficient when it comes to time and quality.
