Abstract
In the TPM literature, numerous frameworks for Total Productive Maintenance (TPM) pillars have
been given proposed by various writers. However, the majority of them are based on research done
in countries like Japan, Italy, the United States, China, and India. Thus, the aim of this study was to
assess the contribution of a few TPM pillars to manufacturing performance in the construction
industry. Data on production, downtime, reasons for downtime, and maintenance are gathered from
the case company and analyzed to determine how the company's equipment is currently performing.
Using a survey approach, 31 corporate employees were given questionnaires, with a 98% response
rate being the end result.
The relationship between the manufacturing performance dimension and TPM Pillars has been
calculated using descriptive statistical methods. In the survey, autonomous and planned
maintenance received the most attention, whereas development management received the least
attention. The TPM Pillars, autonomous maintenance, focused maintenance, planned maintenance,
and training and education are all covered up in the report, despite their considerable contributions
to manufacturing performance, including lower costs, greater equipment availability, strong
delivery, and improved quality.
The results of the study indicate that the company's availability, performance, quality, and OEE
were all increased by 67.74% 71.38% 99.08% 47.91%, respectively, as a result of the application
of TPM. For the case company, a new implementation framework has been suggested. When
completely implemented, all of the chosen pillars have activities that improve shop floor safety.
Maintaining safety initiatives across all pillars will be crucial to creating a secure working
environment.
