During a project’s design, BIM is used to create a model of the finished facility. The data used is highly detailed, resulting in a 3D virtual representation of the structure that’s accurate enough to be used to prove all aspects of construction and long term performance before so much as a shovel hits the ground.
This BIM model is made up of all the components that will be used in its physical construction. If it’s a regular building, a school or office block for example, this will include all the usual things like bricks, doors & windows, thermal insulation, steelwork, pipework, HVAC & plant, sanitary ware, luminaires, ceilings, furniture, floor coverings and even the paint on the walls. These items are called BIM objects and can be likened to the individual pieces of a 3D jigsaw; of limited use on their own, but collectively a really powerful resource.
