Application of Cause Mapping Method in a Building Project with Prefabricated Slabs

This paper explores the application of the Cause Mapping method in a building project with prefabricated slabs in Lima, Peru.Cause Mapping is a root cause analysis technique based on the principle that a "root cause" is typically a system of interconnected factors rather than a single issue.In this case study, the method is used to identify, analyze, and propose solutions to the most recurrent quality defects observed in prefabricated slabs.Common defects identified are fissures in the slabs, misalignments in the modulation with respect to the plans, and incorrectly positioned or non-existent installation points.The study uses interviews and documentary analysis in projects of the construction company under study.The results show that many of the defects arise from discrepancies in the design drawings, manual processes in non-mechanized plants and communication problems between the parties involved.As a response, the study proposes optimizing preconstruction processes, strengthening design review protocols, and promoting the adoption of advanced technologies.A noted limitation of the study is that quality defect data were sourced from company records, which may contain inaccuracies or incomplete information.Future research could benefit from broader data samples and an expanded focus to include other scopes of work.
