Abstract
Rapid urbanisation in Malaysia has led to increased activity within the construction industry, yet negative environmental impacts from construction have been closely linked to climate change. Additionally, increasing project complexity and shorter deadlines are challenging industry players to enhance productivity. To address these issues, the building delivery process in Malaysia must transform to allow seamless exchange of information among project stakeholders while championing sustainability. The implementation of building information modelling (BIM) has been shown to improve output in the construction sector, but its adoption rate in Malaysia is still low. On the other hand, life cycle assessment (LCA) has been frequently used to evaluate the environmental impacts of buildings, but its implementation in Malaysian construction projects is also lacking. Considering the limited adoption and research for both BIM and LCA in Malaysia, an integrated approach is needed to address issues in both areas. Therefore, the aim of this research was to propose a model to support implementation and integration of BIM and LCA for sustainable development in the Malaysian construction industry. To achieve this aim, a nationwide survey of Malaysian construction firms was carried out to identify critical success factors (CSFs) for BIM implementation. Additionally, a systematic literature review and content analysis were conducted to formulate a conceptual framework which effectively integrates BIM and LCA. Together with the CSFs, this conceptual framework was translated into a practical model for BIM implementation and BIM-LCA integration in the local construction industry. Application of this model was demonstrated using a Malaysian public school building as a case study. Additionally, palm oil clinker concrete (POCC) was used as an alternative constructionmaterial for this case study. Using BIM, the selected building was constructed as a digital model based on structural drawings. Visual programming was utilised to semi-automatically generate alternative design options from the original model. Using LCA, the embodied environmental impacts of the conventional and alternative concrete types were calculated. LCA results indicated that a concrete mix utilising 30% replacement of sand with palm oil clinker (POC) was a feasible alternative to conventional concrete. The compressive strength of this mix was approximately 47 MPa which was suitable for structural applications. Use of this specific POCC mix would reduce environmental impacts by 13% and material costs by 9.6% if used as a direct replacement for conventional concrete. It was predicted that application of the model may deliver increased productivity and efficiency over traditional methods in the construction sector. Furthermore, the model may provide building designers with explicit feedback regarding environmental impacts of the proposed structure during the early design stage. This would encourage stakeholders to consider sustainability as one of the core concerns in construction projects alongside cost and time. Moreover, its usage is believed to support efforts to achieve sustainable development in Malaysia and bolster international sustainability goals. This study also contributed to the research gap on BIM implementation, LCA utilisation, and BIM-LCA integration in the local construction sector.
