Abstract

Lean thinking is an essential concept that has emerged in most organizations and industries. This is due to its proven outcomes in improving the process by removing waste and delivering value to the customer. Applying lean has also benefited the process by making it more sustainable by reducing the waste that negatively affects the three pillars of sustainability (Environment, Economy, and Society). Although lean has been established as a concept to improve the manufacturing process, it has extended to cover the maintenance process with reliance on established maintenance principles like Total Productive Maintenance (TPM) and existing lean methods. This paper aims to study and analyze a preventive maintenance (PM) process of a construction company in Qatar and implement lean maintenance methods with TPM to improve the process by minimizing lean waste with a focus on improving process sustainability. The methodology has been assessed through a real case study from a construction project of the company selected. The project equipment preventive maintenance process was analyzed, sustainability indicators were identified, and lean maintenance tools were implemented. The results have revealed that the process has been improved, with sustainability wastes minimized and an overall cost reduction.
