Building Information Modeling (BIM) is a process focused on the development, use and transfer of a
digital information model of a building project to improve the design, construction and operations of a
project or portfolio of facilities. The National Building Information Modeling Standards (NBIMS)
Committee defines BIM as:
“… 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. A
basic premise of BIM is collaboration by different stakeholders at different phases of the life
cycle of a facility to insert, extract, update or modify information in the BIM to support and
reflect the roles of that stakeholder.”
