Construction companies around the world have adopted the Last Planner® System (LPS) to reduce variability, increase workflow and improve reliability on their projects. This study explains the implementation of LPS in an infrastructure (railway bridge construction) project. Strengths and weaknesses of the implementation were examined and possible measures to overcome the experienced challenges were discussed. Finally, attitude changes towards the LPS during the project were measured. Data was collected through case-specific observations, semi-structured interviews with open-ended questions, and two surveys. The findings revealed that the project benefitted from implementing LPS, but benefits could have been reinforced if critical team members had participated continuously in the necessary meetings, followed the system without resistance and maintained their commitments. Additionally, LPS on the Minnevika bridge project was the novel start and detected challenges are often experienced by every organization at the beginning of implementation of a new system. Indeed, the Minnevika bridge project can be considered as a point of departure and being persistent will help the parties to benefit even more in the next project.
