Lean Construction: Implementing a Last Planner System on Mining Projects

The purpose of this research paper was to explore the potential benefits on construction performance by implementing the Last Planner System on mining infrastructure projects in the South African mining industry.
The benefits of lean construction methods were identified through a literature review and applied on two mining project case studies. This was through applying the Last Planner System, which is a function of lean construction. The research was twofold. The first part involved the measurement of the impact on Last Planner System application through earned value techniques on secondary project data. The second part sought to establish the lean construction success factors leading to construction performance improvement. The latter was done through a research questionnaire distributed to the project owner’s team, contracted parties and the Last Planner System facilitators.
The results revealed a positive correlation between the Last Planner System application and planned percent complete. However, the observed performance achieved during the Last Planner System pilot was not sustained. The success factors and benefits considered most evident in the case study pilot differed among the three stakeholder groups.
The study’s findings are expected to guide construction stakeholders to better define performance measures and focus on factors required to make Last Planner System implementation more effective in the South African mining sector.
