Implementation of Last Planner® System in an infrastructure project

Abstract

Since the establishment of the Last Planner® system (LPS) by Ballard and Howell, multiple studies have been conducted to evaluate the implementation of LPS in many construction projects. However, few studies have recorded the implementation process in infrastructure projects. This study investigates the implementation of LPS in an infrastructure project (Minnevika Bridge project), detect the challenges that arise during the implementation, and suggest measures to overcome these challenges. Several data collection methods were used in an action research approach; namely, a single case study, a literature study, non-participant/participant observations, six semi-structured interviews and two surveys. The study revealed that the project followed the best practice process map for LPS implementation mentioned in the literature. Moreover, the project experienced challenges described in the literature that tend to arise when adopting LPS, similar to those reported from other construction projects (e.g. participants’ resistance to the system). The study concludes with suggested measures to overcome these challenges (e.g. sufficient training and openness towards the LPS). Finally, the researchers represent challenges that are not clearly described in the literature (e.g., fear of responsibility when making the commitments).
