LEAN CONSTRUCTION IMPLEMENTATION IN THE CONSTRUCTION OF AN AIRPORT RUNWAY

Abstract

This study explores the application of Lean Construction in the expansion and restoration of an airport runway, a project marked by complexities and high demands. The aim of this paper is to address the following research question: "What is the effectiveness of the daily scheduling approach compared to the weekly horizon approach for short-term scheduling in complex and variable infrastructure projects?". To answer this question, an extensive literature review was conducted, anchored in the action research method. It was found that the adoption of daily schedules may be more efficient, as it allows for greater agility in responding to client needs, accommodating constant changes requested by stakeholders, and managing uncertainties inherent in infrastructure projects of this nature. The results highlight significant advances in long-term adherence and project management effectiveness, despite encountered obstacles such as coordination among different stakeholders and adaptation to variabilities. The Percentage of Constraint Removal (PCR) improved by 22% from the start to the end of the project, while maintaining a 93% adherence to the Master Planning.
