Abstract

Material management is an important aspect of construction projects because it affects cost, quality, and project duration. Improper management can cause construction waste, including leftover materials, material damage, material loss, and rework. This study aims to identify waste material, analyze its causes, evaluate Lean Construction implementation, and formulate improvement efforts in the Amanah Residence Housing Project, Gadut, Agam Regency. This study used a descriptive qualitative method through observation, interviews, and documentation. Data were analyzed using waste identification, Fishbone Diagram analysis, and Lean Construction evaluation. The results showed that the dominant waste-causing factors were Man, Material, and Environment. The highest causes were lack of care, improper storage and material damage, and unfavorable weather. Lean Construction implementation reached 28.57%. Improvement efforts include better supervision, storage, distribution, coordination, and continuous improvement.Keywords: Lean Construction; Material Management; Waste Material; Fishbone Diagram; Housing Project
