5D BIM for Carbon and Cost Forecasting: Transforming Decisions for Sustainable Projects*

Abstract:

Achieving sustainable construction requires that cost, schedule, and carbon considerations be integrated from the earliest design stage. This keynote examines how 5D BIM—where 3D geometry is linked with time and cost data—can be extended to include carbon forecasting to support low-carbon, financially sound decision-making. By combining BIM-based quantity take-off with carbon factors and cost databases, project teams can simulate design alternatives, evaluate carbon–cost trade-offs, and optimise materials and construction strategies. Drawing on global benchmarks and Malaysian case studies, the presentation demonstrates how 5D BIM improves prediction accuracy, enhances transparency, and supports national decarbonisation goals.

Title of the speech:

Designing for Sustainable Futures with BIM

Abstract:

The built environment faces increasing pressure to improve environmental performance while meeting rising design and operational expectations. This talk presents recent research and development on integrating Building Information Modelling (BIM) with computational algorithms to evaluate and optimise sustainable building performance. It highlights how BIM-based workflows, coupled with simulation, parametric modelling, and data-driven optimisation, can support early design decisions, enhance resource efficiency, and improve overall sustainability outcomes. The session demonstrates emerging methods, prototype tools, and case studies that show how digital design intelligence can drive greener and more resilient buildings for a sustainable future.

Lean Construction: The Way to Deliver Sustainable Infrastructure

Abstract:

Lean construction has emerged as a transformative approach in the delivery of sustainable infrastructure, particularly in contexts facing rapid urbanization, resource constraints, and frequent natural disasters such as Indonesia. By integrating principles originally developed in manufacturing—such as maximizing stakeholder value, minimizing waste, and fostering collaboration—lean construction redefines how infrastructure projects are planned, designed, constructed, operated, and decommissioned. This paradigm shift moves beyond traditional project management, emphasizing continuous improvement and the holistic consideration of economic, social, environmental, and institutional sustainability throughout the infrastructure lifecycle. Lean construction methods, including the Last Planner System, Takt Planning, and Integrated Project Delivery, enable more reliable workflows, efficient resource utilization, and adaptive responses to disruptions, thereby enhancing both sustainability and resilience. As sustainability evolves from an intermediate to a final value in construction, lean principles ensure that infrastructure projects deliver long-term benefits not only to paying customers but also to supply chains, local communities, wider society, and future generations. Ultimately, lean construction is positioned as the essential pathway for delivering infrastructure that is both sustainable and resilient, capable of meeting present needs while safeguarding the ability of future generations to thrive.
