Practices on Project Performance: A Comparative Analysis of Traditional and Lean Construction Methods in Selected Construction Companies in Metro Manila

Construction practices in Metro Manila predominantly rely on traditional methods, with lean construction still not widely adopted or recognized in the Philippines. This comparative analysis investigates the impact of these two approaches on project performance within selected construction companies in the region. The research explores the differences in implementation, identifies construction workers' perceptions of their performance under each method, and evaluates the effects of lean construction practices compared to traditional methods. The study also assesses work efficiency and performance improvements using lean and traditional methods in terms of quality, time, and cost—the three critical project management control variables. A comparative quantitative research design is employed, focusing on construction workers and professionals within the region. Data is collected using a structured questionnaire, designed to capture detailed insights into participants' perceptions of both construction methods. Statistical analysis, including the Kruskal-Wallis test and correlation coefficient, will be applied to evaluate differences and correlations between the two methods. The findings aim to provide insights for improving construction practices based on the comparative outcomes of lean and traditional construction approaches.
