We often hear of the great tectonic shift that digital technologies have brought to almost every aspect of our lives, but in one particular yet understated way, architecture has been revolutionized by computerization. Building Information Modeling (BIM) is a background revolution that has implications on every stage in the building process from development through construction and onto the lifecycle of the building. As defined by the US National Building Information Model Standard Project Committee:
"Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolition." 
While that gives some indication of BIM’s applications, many people may still be wondering how such a shift came about, what are its present applications and benefits, and how it will shape architecture’s future?
