Building Information Modeling (BIM) is a 3D model-centric process that increases the transparency and consistency of data in the planning, design, and operations phases of infrastructure projects. Economic cost benefit analysis (CBA) is currently used in the early planning stages of infrastructure projects to decide whether to proceed and, occasionally, which alternatives to design. BIM is used extensively in the design phase of infrastructure projects. CBA, if supercharged with risk analysis and multiple account and stakeholder views, can be dropped into a BIM chassis with exciting possibilities.
Automating CBA reduces cost, and bolting CBA into a BIM model enables important decisions made by the engineers and architects to be guided by rigorous economic analysis
CBA is becoming standard and cheap. At the same time, open data initiatives have allowed powerful BIM models to be populated easily and cheaply. Put simply, CBA in BIM gives architects, engineers, designers, and planners access to decision-making tools that help them decide what to build, how to build it, what the risks are, and who benefits.
CBA-BIM /si-bä-bim/ noun
CBA-BIM is a proposed framework for evaluating the Sustainability Impact Value (SIV) of infrastructure projects. The power of geographical information systems and economic SROI process means that climate risk analysis can be done early in the planning stages and often during the design stage.
