CHALLENGES IN LEAN CONSTRUCTION: INSIGHTS FROM THE INDIAN CONSTRUCTION SECTOR

Abstract

The construction industry has very strategic and vital role in development of the country. Currently, the construction sector experiences rapid growth. However, the sector faces project delay, cost overrun challenges. Lean principles offer a systematic approach to address these inefficiencies by minimizing waste and optimizing resources with maximize values. This study investigates the challenges of implementation of lean principles in the construction industry through comprising literature review and quantitative survey was conducted among industry professionals to gather insights on the key factors hindering lean adoption. The analysis included multi linear regression techniques to understand the relationship between key variables and to identify significant factors impacting lean implementation and a fishbone diagram was developed to visualize the root causes. The finding highlights that people, management and knowledge are the major factors hinder the adoption of lean practices. The study also emphasizes the importance of top management support, comprehensive training programs, and active involvement of employees in overcoming these challenges. Practical solutions such as the Last Planner System, Kaizen, Just-In-Time practices, and BIM are proposed to enhance lean adoption.
