The adoption of lean construction techniques in construction industry can eliminate waste and increase profit, and this paper is to test the maturity of implementation of lean construction tools in construction project, as well as the impact of lean construction tools on individual performance. In this research, five widely used lean construction techniques were selected (Last Planner system (LPS), visualization tool, six step plan(6S), Just-in-time (JIT) and Total quality management (TQM)), and individual performance was divided into two dimensions: task performance and contextual performance. The data collection methods included interviews and questionnaires, and the data analyzed via SPSS software. The results showed that the highest maturity implementation of lean construction tools in the investigated projects was TQM, had positive impact on individual performance, while LPS was the lowest maturity tool and had least impact on individual performance; for task performance, 6S was the most effective technique, and for contextual performance, the most effective tool was visualization tool. This study provides theoretical support and guidance for construction enterprises to select lean construction techniques to improve individual performance.
