SUPPLY CHAIN DEVELOPMENT IN GENERAL CONTRACTING THROUGH LEAN THINKING

Abstract

In the construction industry, increasing efficiency and reducing waste is an urgent challenge. The application of lean thinking offers an opportunity to improve the success of construction projects by optimizing material flow and enhancing information flow. This study demonstrates, through the Hungaroring construction project, how construction processes can be supported by digital solutions to optimize material flow and information management. The application of the just-in-time (JIT) principle minimizes storage costs and ensures timely availability of materials. Through digital inventory management and supply chain management integrated with IT solutions, more efficient coordination among stakeholders can be achieved. Value stream mapping was used to analyse the processes, revealing the deficiencies in the current operations, helping to reduce waste and design the optimal system. The results confirm that combining lean principles and digitalization can lead to significant time and cost savings in construction projects.
