Risk Assessment in Construction Using FMEA to Improve Quality: A Multi-Level Analysis

Abstract: This study employs Failure Mode and Effects Analysis (FMEA) to assess risks across five construction levels (Basement, Lintel, Roof, Casing, and Finishing). Surveying 750 stakeholders (architects, designers, engineers, supervisors, workers), we identify 12 critical failure modes, their root causes & severity. Key findings reveal supervisors and workers as most accountable (26-39% responsibility), with "Unsafe working conditions" & "No training" as dominant causes. We propose targeted interventions to mitigate risks and enhance quality.
