Abstract

This paper shows a detail implementation and lessons learned from the Last Planner System (LPS) in the context of a social housing program of the government of Chile. Specifically the "Condominio Juanita Aguirre" (CJA) project in the commune of Conchali in Santiago, Chile, which includes the construction of 80 apartments of 56 m², in buildings of 4 stories high on a contractual period of one year. We followed the trajectory from the general contractor perspective, Oval Company, which has extensive experience in the construction of social housing. This company has obtained highly variable projects results in the past, and thus the company decided to implement the Last Planner System (LPS) in the CJA project. This research measures the results of the implementation throughout the construction process. Additionally, we make a comparison against previous projects of similar characteristics built by the same company with traditional management systems. Finally, the research shows that CJA project achieved significant improvements compared to previous projects, in the areas of: construction schedule, construction costs, safety, and final quality of housing.
