The integration of BIM and IBS: a case study of Harmoni Elmina 1, Selangor, Malaysia / Farah Salwati Ibrahim ... [et al.]

Innovative construction practices drive progress in the development of sustainable, efficient, and high-quality residential buildings. Yet, this practice in residential buildings remains limited. This study investigates the innovative construction practices applied in the development of Harmoni Elmina 1, with a focus on the integration of Industrialised Building Systems (IBS) and Building Information Modelling (BIM). Through a case study approach, key innovations were explored through interviews and project documentation analysis. BIM played a crucial role in the planning, design, and construction stages, reducing error, waste, and risk while enhancing cost efficiency and project progress. Moreover, 10 IBS components, including precast concrete, bubble deck systems, precast reinforced concrete, and prefabricated components, were utilized, further enhancing construction efficiency and quality. The findings demonstrate that integrating BIM and IBS significantly improved project performance, conserve project duration by 28-33%, preliminary cost by 30%, and achieving near zero construction waste. Inclusively, this case study offers valuable insights for industry professionals by showcasing best practices in BIM and IBS integration, providing a model for improving project outcomes, resource efficiency, and sustainability in the built environment. Projects like Harmoni Elmina 1 highlight the transformative potential of innovation in improving living standards, and promoting more sustainable built construction industry.
