Abstract

Megaprojects, characterized by their complexity, large scopes, and diverse stakeholders, often face inefficiencies, cost overruns, and uncertainties. Lean Construction (LC) has emerged as a transformative approach to address these challenges, enhancing efficiency, collaboration, and sustainability in megaproject delivery. This study bridges the gap between theory and practice by developing a comprehensive LC implementation model for megaprojects. It focuses on three objectives: identifying key LC practices through a literature review, validating them via expert interviews, and ranking them using the Fuzzy Relative Importance Index (FRII) Employing a mixed-methods approach, the research combines a systematic literature review, expert insights, and a survey of 379 construction professionals to evaluate and rank critical LC practices. The study identifies 35 essential practices, with Integrated Project Delivery (IPD) systems as the most critical, followed by the Last Planner System (LPS), Value Stream Mapping (VSM), Building Information Modelling (BIM), and Target Value Design (TVD). These practices address barriers to LC adoption and megaproject challenges. By providing a prioritized framework, the study offers actionable insights for industry leaders and policymakers, enabling them to focus on impactful strategies for sustainable megaproject delivery. The findings advance LC theory and provide practical tools for driving innovation in the construction industry.
