A conceptual framework for implementing lean construction and building information modeling (BIM) in post-disaster housing reconstruction projects

The occurrence of natural disasters in Indonesia every year results in massive damage to people's homes. It requires a fast and appropriate post-disaster housing reconstruction (PDHR) strategy. The building firm or contractor is among the most significant contributors; in post-disaster conditions, the contractor has to work in a project environment that is much more complicated than conventional projects, and this often results in poor contractor performance. An approach to improve contractor performance is the application of Lean Construction. In line with this linking, the function of the Building Information Modelling (BIM) tool in the application of Lean has also proven effective in conventional projects. However, studies focusing on its simultaneous application to PDHR projects are still lacking. A conceptual framework that can be applied to specific Lean and BIM implementations in PDHR projects is needed to address this issue. This paper proposes a conceptual framework by identifying and analyzing various previous studies as a proper basis. The study shows several Lean Construction and BIM factors relevant to contractor performance indicators in post-disaster housing reconstruction projects.
