To facilitate checking of different floor areas in digital general building plans (GBP) in Building Information Modelling (BIM) format, the Buildings Department (BD) and the Lands Department (LandsD) have jointly commissioned a consultant to develop a common area calculation methodology and plug-in tools of two native BIM software (i.e. REVIT and ArchiCAD) to streamline the data extraction and conduct automated checking of floor areas against the requirements under the Buildings Ordinance and lease conditions (the Area Tool*).

The Area Tool, which may also serve as a design review tool, saves time and manpower in verifying numerical accuracy and in updating and rechecking when amendments to the design are required, thereby enhancing quality and certainty of the submissions.

In this webinar, representatives from BD and LandsD will brief you on the key features of the Area Tool and demonstrate how the created automation could make the complicated calculation process easy, dispensing with going through a mountain of detailed requirements in regulations/practice notes.  They will also introduce the Area Tool's smart functions for automated parameter input, data quality check and batch import of computation results to facilitate the preparation of calculation sheets for GBP submission.

Members with job duties involving GBP submission to BD and LandsD should not miss this opportunity to equip yourself with better knowledge on this newly developed BIM Area Tool.

*The Area Tool is available in BD Website and LandsD Website for free download and use.  Attendees are encouraged to download the tool and template for trial and view the relevant video guides before the webinar.
