As-built or as-constructed building information model

According to PAS 1192-2:2013: Specification for information management for the capital/delivery phase of construction projects using building information modelling (BIM), (now replaced by BS EN ISO 19650) an as-built or as-constructed building information model is a:

'A model consisting of documentation, non- graphical information and graphical information defining the delivered project.

As-built” is defined as the record drawings and documentation defining deviation to the designed information occurring during construction at the end of the project.

“As-constructed” defines the defect and deviation to the designed model occurring during construction. The “as-constructedmodel and its appended documentation are continually updated through re-measurement as construction progresses. This allows for deviation to be reviewed with respect to the following packages and making knowledgeable assessment of impact and resolution.'
