Lean Integrated Project Delivery for Construction Procurement: The Case of Sri Lanka

The choice of proper procurement methods has an impact on the overall productivity and sustainability of construction projects. The current procurement methods have alerted the construction industry (CI) due to the exacerbating fragmentation among parties and the resulting low level of productivity. Therefore, introducing a new procurement system to eliminate the above challenges is imperative to the CI. Therefore, this research investigated the applicability of lean integrated project delivery (LIPD) as a construction procurement system and developed a framework for its successful implementation. A qualitative exploratory approach was adopted, informing an interpretivism stance. Accordingly, semi-structured interviews with 15 Sri Lankan (SL) CI experts were conducted to determine the applicability of the LIPD concept in a real-life CI context. Qualitative content analysis was used to analyse the collected data. This research identified the significance of LIPD compared to existing procurement methods, which may contribute to the long-term planning and management practices in the CI. However, the findings elicited several barriers that could hinder successful LIPD implementation. As a result, some of the strategies discovered include providing LIPD training and awareness, obtaining expert support, and encouraging professionals. This is the first study of its kind to reveal a LIPD framework in a developing country like SL without restricting itself to a specific construction type. Therefore, this study is expected to impact the global CI by paving the way for LIPD as a new procurement system to improve the performances of similar CIs in developing countries across the world.
