The Impact of Lean Construction Tools on Environmental Sustainability in Morocco: A Structured Survey Analysis

Abstract

AbstractThis study explores the influence of Lean Construction (LC) techniques on environmental sustainability in the Moroccan construction industry. Known for minimizing waste and maximizing value in production systems, LC not only holds promise for improving efficiency and competitiveness but also has the potential to address environmental concerns. This study aims to fill this gap by assessing how LC can contribute to the environmental performance in Morocco based on a survey by structured questionnaire involving 330 Moroccan construction professionals. The methodology includes a comprehensive survey and analysis using SPSS V26.0. Key findings indicate a significant positive impact of LC on environmental performance, particularly in reducing material use, energy consumption, pollutant release, and non-product output. Notably, non-product output emerged as the most significantly influenced factor by LC practices. The study also reveals a differential impact of LC based on organizational characteristics, with distinct influences observed between contractors and consultants, especially in pollutant releases. These insights underscore the potential of LC in fostering environmental sustainability within the Moroccan construction sector. This survey is crucial for a more holistic understanding of LC’s impact, aligning with global environmental goals and the specific needs of the Moroccan construction industry.
