Abstract: In the context of high-rise residential projects, managing defects is crucial for process efficiency and customer satisfaction. Using a case study of a nine-tower apartment complex in The Greater Jakarta Area, this study intends to analyse and prioritise failure modes as well as offer action plans for dominant defects for high rise residential complexes. It does this by integrating four analysis techniques: failure mode effect analysis (FMEA), Pareto analysis, fault tree analysis (FTA), and the Delphi method. The research identifies four primary defects using Pareto analysis. FTA and FMEA help uncover failure modes, failure effects, root causes, and existing controls. By involving a panel of experts, the Delphi technique establishes the risk priority number (RPN) for each failure mode. The findings highlight top six specific failure modes related to door and framework, wall and masonry work, ceramic tiling work, and painting work. Action plans are proposed to mitigate these defects in high-rise residential projects.

Keywords: Delphi; defect; fault tree analysis; FTA; failure mode effect analysis; FMEA; Pareto.
