4.1          Administrative Requirements

  • The BIM files should be stored in a non-rewritable DVD-ROM in ISO/IEC 13346:1995 format (i.e. DVD format). Except otherwise agreed by the BA, all other electronic submission media are not acceptable.
    • Each BIM file should be limited to the size of 500MB. Each BIM  file should contain 3D model, views, schedules, as well as the pre-set drawing sheets including plans, area diagrams, calculations, etc. for the production of the hardcopy of prescribed plans. The text file should be included in the DVD-ROM to describe the linked files’ hierarchy structure.
    • BA currently accepts BIM native files created by (i) Revit version 2017 or later and (ii) ArchiCAD version 21 or later only. As BIM technology is fast developing, there may be add-ons assistant programs or in-house scripts used for enhancing automation in the BIM file production. Add-ons or other implanted automation may cause the submitted BIM file not  usable by BD’s standard Revit or ArchiCAD software. It is the APs’ responsibility to ensure that the purposes of the BIM model are served, as elaborated in the Guidelines, without relying on add-ons or additional scripts.
    • The use of software, other than Revit and ArchiCAD, requires prior acceptance from the BA. As a general rule for such prior acceptance, the APs should submit at least one test sample together with the enabling software to the BA for installation and testing. For the avoidance of doubt, BA does not accept any web based BIM software.
    • Revit files should be saved in “.rvt” format and ArchiCAD files in “.pla” format only. All other lightweight, compressed or zipped file  formats such as “.dwf”, “.dwfx” and “.bimx” will not be accepted.
    • Drawing title blocks with drawing number, revision number, legends, site

/ project title, drawing title, etc. as detailed in Section 5.4.1 should be inserted in every drawing for identification purpose.

  • BIM files submitted in DVD ROM format should be self-contained and detached from the originating server. It shall be able to  be  opened on any standalone computer with the abovementioned software. All “X-Ref” files for the BIM model such as xlsx and pdf files should be stored in respective sub-folders in DVD ROM, and the link between all “X-Ref” files and BIM main file should be appropriately connected.
