Lean construction applies manufacturing efficiency principles to construction. Value stream mapping identifies value-adding and waste activities. Elimination of waste reduces cost and schedule. Muda (waste) includes waiting, movement, and rework. Pull scheduling coordinates work based on actual pace rather than pushing tasks. Last planner system synchronizes all trades. Weekly coordination meetings ensure readiness. Just-in-time delivery of materials reduces on-site storage. Continuous improvement through regular reflection identifies improvements. Worker empowerment enables frontline suggestions. Standardization of processes and procedures reduces variability. Template approaches for repeated tasks improve efficiency. Visual management using kanban boards tracks work status. Color coding shows readiness and progress. Real-time information improves decision-making. Metrics tracking progress encourage engagement. Defect elimination prevents rework. Quality focus at source prevents problems. Integrated product development involves stakeholders early. Early problem identification prevents costly late changes.
