BIM Introduction
What is Building Information Modelling (BIM)?
Building Information Modelling is digital representation of physical and functional characteristics of a facility; creating a shared knowledge resource for information about it and forming a reliable basis for decisions during its life cycle, from earliest conception to demolition.
This image contains a diagram that illustrates the life cycle of the model and its uses. The key thing to recognise is that BIM is about process rather than technology or software. BIM is creating a digital record of an asset and a central source of truth and shared knowledge.
Degrees of simulation
BIM is often referred to in dimensions.
-
3D refers to design and 3D modelling to communication design intent
-
4D adds the aspect of time to a project so the models are aligned to the programme to communicate construction sequencing and timelines
-
5D adds the aspect of cost to a project – quantities and data is harvested from the model to
-
6D is the operational part of BIM. This is where a model has been handed over to a client and they can then use this to assist in asset management activities. Data can be assigned to model objects that can then be used by a client to assist in life cycle cost programmes.
Why would we use BIM?
