Building Information Modelling (BIM) is the process of generating and managing building data during its design, construction and during the building or assets life cycle. Typically, the process uses three-dimensional building modelling software to increase productivity of consultants and contractors during the whole asset life cycle. The process produces the Building Information Model database, which encompasses building geometry, spatial relationships, geographic information, quantities and properties of building elements. It is a new way of working using new technology to facilitate project management, better construction process control, cross-disciplinary collaboration, communication with external stakeholders, decision support and risk management.
