Abstract:
Integrating lean learning practices in construction is paramount for elevating project quality, thus bolstering industry competitiveness and sustainability. However, there exists a notable dearth of research addressing lean learning practices specifically within the Sri Lankan construction industry. Therefore, this study aims to investigate the state-of-the-art lean learning practices in the Sri Lankan construction industry. An interpretivism stance is adopted, and a qualitative research approach is used. A case study strategy was adopted, focusing on three large Sri Lankan contracting organisations selected through purposive sampling. Data was collected through semi-structured interviews with fifteen experienced individuals, and document reviews. The collected data was then analysed using code-based content analysis using NVivo 12. Different lean tools, including Last Planner System (LPS), Value Stream Mapping (VSM), and 5S, are presently being utilised in an ad-hoc manner within contracting organisations. Comprehensive lean learning practices, including regular training sessions, workshops, and hands-on exercises, were emphasised to translate theoretical lean concepts into practical knowledge. By identifying the ad-hoc nature of their implementation, the study shed light on the importance of structured lean learning initiatives tailored to different organisational levels. It is recommended to implement clear communication channels, ongoing training, and a culture of continuous improvement for sustaining lean transformation in the Sri Lankan construction industry. By focusing on lean learning practices, the topic acknowledges the continuous improvement aspect of lean construction, emphasising the need for ongoing education and skill development within construction teams. This study has the potential to contribute valuable insights to both academia and industry practitioners seeking to enhance efficiency, quality, and sustainability in construction projects.
