Abstract

The objective of this study is to adapt the Last Planner System (LPS) for managing subcontractors in natural gas installations within repetitive housing projects, using BIM technology for enhanced modeling and efficiency. Our methodology was applied to a large-scale, multi-family, low-cost housing project in Lima, Peru. Through this application, we achieved high Percent Plan Complete (PPC) values and improved collaborative planning practices. This paper makes distinct contributions to the subcontractor management literature: (1) it demonstrates the practical integration of LPS with BIM to streamline subcontractor activities in a real-world setting; (2) it offers a novel approach for determining optimal Takt Time Planning for daily and weekly schedules, enhancing the predictability and reliability of subcontractor work; and (3) lessons learned from the implementation provide a roadmap that can be adapted to other subcontractor management scenarios.

Keywords
