Abstract
The implementation of the Last Planner System (LPS) and off-site construction has been identified as means to improve production management and, thus, increased productivity and project performance. Nevertheless, the sector lacks an evaluation system that allows clients, designers, and contractors to identify areas for continuous improvement and encourage further adoption of the LPS and off-site manufacturing. Therefore, this paper aims to analyze performance during the construction of the reinforced concrete structural frame of two similar high-rise residential projects in Lima-Peru. Both projects used the LPS. However, the first case used traditional on-site poured slabs, and the second used a mix of precast slabs and additional on-site pouring. Data was collected during the construction process and included labor data, production data, schedules, site visits, and observations. Data were analyzed to obtain cycle times, production and productivity rates, and labor density. The results show that the building using precast slabs performed 14% better in terms of time and 16% in terms of productivity compared to the traditional slab. Further research can measure performance and productivity by implementing other precast components such as shear walls, beams, and columns.
