Abstract

Highway infrastructure projects are often characterized by complex workflows, extended timelines, and cost overruns, frequently resulting from inefficiencies in traditional construction methods. Lean Construction, a methodology derived from Lean Manufacturing principles, emphasizes waste reduction, continuous improvement, and value generation for the client. This paper explores the application of Lean Construction principles to highway projects with the aim of improving overall project efficiency, reducing delays, and enhancing resource utilization. Through a review of existing literature and analysis of case studies, the study identifies key Lean tools—such as Last Planner System (LPS), value stream mapping, and just-in-time delivery—that have proven effective in streamlining construction processes. The findings suggest that integrating Lean Construction practices into highway projects can significantly improve coordination, minimize waste, and foster a culture of collaboration across all stakeholders. The paper concludes by recommending practical strategies for implementing Lean principles in the planning, execution, and monitoring phases of highway projects to achieve timely and cost-effective project delivery.
