Abstract

Surface mining operations have particular attributes resulting from geological variability. This paper aims to show improvements gained from the implementation of the Last Planner System (LPS) in open pit mining. Lean Construction concepts and principles had never previously been implemented in this kind of heavy civil construction project in Peru. With the Last Planner System of production control implemented, it is anticipated that productivity will improve as well as planning reliability (Ballard and Howell 1997) to match the degree of variability in the project’s characteristics. This is likely to help the company currently under analysis, GyM, to increase efficiency and generate value in clients and stakeholders of all surface mining projects. The best practices in planning and operations control have been collected from two case studies, the Shougang and Brocal projects, in which there was successful implementation of Last Planner System (LPS) in big surface mining services carried out for GyM. This paper will analyze results from both, and propose adequate means to a sustainable LPS in all open pit mining projects.
