Building Information Modeling

• Building Information Modeling

(BIM) which has been defined

as “a digital representation or

visualization of physical and

functional characteristics of a

facility. In addition BIM serves

as a shared knowledge

resource for information about

a facility forming a reliable

basis for decisions during its

life-cycle from inception

onward”
