BIM stands for Building Information Modelling… or at least that’s the original use of the acronym. Over the years, as BIM has evolved, some have also referred to it as ‘Building Information Management’ or ‘Better Information Management’. Fundamentally, BIM is the term used to describe the process of developing a digital model and associated data to represent a building or infrastructure project. It’s worth noting that the term is a verb. BIM is not a software format or a single piece of technology. The utilisation of BIM (tools, processes, workflows, protocols, technology) results in substantial efficiencies for various project stakeholders across all project stages. From site evaluation and concept design through to facility management and eventual demolition, and from building product manufacturers to facility managers, BIM is used to drive efficiencies and better quality outcomes. As far as the design aspect of BIM is concerned, this is usually defined (broadly / generally) as the utilisation of parametric-capable software such as Revit or Archicad to create a data-rich 3D model that contains both graphical and non-graphical information to generate outputs such as Architectural and Engineering drawings, visualisation and schedules, and to perform analysis and coordination tasks such as clash-detection, costings, sustainability evaluation and cost estimates.
