What is BIM?
BIM is an acronym for Building Information Modelling. BIM models usually contain several types of building information such as structure, build-out, mechanical, utility, energy, geographic and occupant data. The concept of BIM is to have an accurate computer simulation of a building that can be referenced over the lifecycle of the building. BIM models may be used to prototype construction, costing, spatial requirements, energy efficiency, material usage, site safety, security, tenant activity and other building performance characteristics. An accurate BIM model can be very useful in the planning and management of a building over time.
Generally, BIM models are three dimensional in nature and their components are parametric. Parametric objects are generally meant to simulate real-world objects and contain dimensional, material and meta data (such as manufacturer's specifications).
There are several BIM software packages on the market today including Autodesk Revit, Graphisoft Archicad, and Bentley Architecture. BIM is experiencing rapid growth in the fields of architecture, engineering, construction, and building management. BIM models can be developed pre-construction at the design and development phase of a building, or post-construction from as-built information collected on-site.
