GOVINDASAMY, T.  and  BEKKER, M.C.. Lean construction: Implementing the Last Planner System on mining projects. J. S. Afr. Inst. Min. Metall. [online]. 2024, vol.124, n.1, pp.15-24. ISSN 2411-9717.  http://dx.doi.org/10.17159/2411-9717/1695/2024.

The potential benefits of implementing the Last Planner System (LPS) on mining infrastructure projects were explored through two case studies in the South African mining industry. The first part of the study involved measurement of the impact of LPS through earned value techniques on secondary project data. The second part sought to establish the lean construction success factors leading to improvements in construction performance. This was done by means of a research questionnaire distributed to the project owner's teams, contracted parties, and the LPS facilitators. The results revealed a positive correlation between LPS application and planned percentage complete. However, the performance achieved during the LPS pilot was not sustained. The success factors and benefits considered most evident in the case study pilot differed among the three stakeholder groups. The findings are expected to guide construction stakeholders to better define performance measures and focus on factors required to make LPS implementation more effective in the South African mining sector.

Keywords : Last Planner System (LPS); success factors; earned value management (EVM); construction.
