Building Information Modelling (BIM) technology is identified as one of the key drivers to enhance the design, construction and project management in the construction industry. Buildings Department (BD) encourages Authorized Persons (APs), Registered Structural Engineers (RSEs) and Registered Geotechnical Engineers (RGEs) to consider adopting BIM in their building projects.

BD accepts the use of computer for calculating floor areas of buildings in the preparation of general building plans (GBP) submission. Practice Note for Authorized Persons, Registered Structural Engineers and Registered Geotechnical Engineers (PNAP) ADM-19 sets out the rules and pre-requisites regarding such computer use. If BIM technology is used in the preparation of GBP, this  Guidelines for Using Building Information Modelling in General Building Plans submission (the Guidelines) should be followed.
