Lean Design Management (LDM) is a response from the lean construction community to overcome the chaotic design process in the AEC industry. Many tools, processes and methods were adapted to the context of design with limited success. This paper presents the use and adaptation of different lean design tools and processes in two phases of a major infrastructure project in the UK. The project is the new high-speed railway to be the backbone of the UK transport network, and it is considered Europe’s largest infrastructure project. The lean design implementation occurred in a Joint-Venture (JV) that had been awarded the main works civils contracts. This paper also compares the results of combined use of adapted last planner in phase 1 and adapted design structure matrix in phase 2, and identifies some of the practical challenges and benefits of the implementation of lean design management. The main contribution of this paper is the contextualisation of different project organisational structures and its influence on the success of the LDM tools implementation. Moreover, a common result for both phases is the enhancement of project communication, collaboration, and transparency of information for planning and control of the project activities.
