THE INFLUENCE OF LEAN CONSTRUCTION PRINCIPLES ON PROJECT PERFORMANCE

Abstract

Lean construction principles have emerged as a transformative approach to improving project performance by minimizing waste, enhancing efficiency, and optimizing resource utilization. This study explores the impact of lean construction principles on project performance by analyzing key metrics such as cost reduction, time management, quality enhancement, and overall site productivity. The research methodology involves a structured questionnaire survey targeting professionals involved in construction projects, including project managers, site engineers, supervisors, and contractors. The collected data is statistically analyzed using SPSS software to identify correlations and trends related to lean construction adoption and its effects on project outcomes.

The study is conducted on multiple active construction sites where lean methodologies such as Just-In-Time (JIT), Last Planner System (LPS), and 5S implementation are evaluated. The survey assesses factors such as the level of lean adoption, its perceived benefits, and challenges faced during implementation. SPSS analysis is used for descriptive statistics, correlation analysis, and regression modeling to determine the relationship between lean construction practices and project performance indicators. The findings highlight critical insights into how lean construction influences cost savings, waste reduction, and project efficiency, providing valuable recommendations for enhancing construction management strategies.

This research contributes to the existing body of knowledge by offering empirical evidence on the benefits of lean construction in real-world scenarios. It also serves as a practical guide for construction professionals seeking to integrate lean methodologies into their projects for improved outcomes
