The use of Building Information Modelling (BIM) is an innovative approach to building design and construction. The Buildings Department (BD) encourages authorized persons (AP), registered structural engineers (RSE) and registered geotechnical engineers (RGE) to consider adopting BIM in their building projects under the Buildings Ordinance (BO).
There is a wide range of applications of BIM on new building development and alteration and addition works which are considered useful to facilitate BD in processing plan submissions. Some examples of BIM applications are given in Appendix A of the Practice Note for Authorized Persons, Registered Structural Engineers and Registered Geotechnical Engineers (PNAP) ADV-34. The project AP/RSE/RGE are encouraged to provide BD with a soft copy of the computer modelling information under the specified format for reference. Details of the format and software version of the BIM files are specified in PNAP ADM-19 and PNAP ADV-34.
Whilst BIM is submitted as a kind of supplementary information for reference, BD processes approval of plans under the BO based on the information contained in the plans. In case of any discrepancy between the plans and BIM submitted, the plans shall prevail.
