Part 1: Concepts and principles - provides recommendations on how to manage building information. Part 2 of this standard; ISO 19650-2 Organization of information about construction works - Information management using building information modelling. Part 2: Delivery phase of assets. - provides information management requirements in the delivery phase of assets. Buy / Download BS EN ISO 19650-1:2018


It is expected that majority of large scale projects in the UK and elsewhere follow this standard to be in line with the latest industry protocols. The UK BIM Alliance published a guide to help individuals and businesses in the UK understand the fundamental principles of this standard. This is now incorporated in UK BIM Framework Standards & Guidance.

Drawing Numbering Convention

According to ISO, issued drawings should follow Project – Originator – Volume/System – Level/Location – Type – Role – Number – Suitability – Revision.

For detailed explanation of each field please read guidance by NG Bailey or by Viewpoint

Field 1 Field 2 Field 3 Field 4 Field 5 Field 6 Field 7 Field 8 Field 9
Project Number Originator Volume / System Level / Location Type Role Number Suitability Revision
12345 CMP Z1 L1 DR A 10001 S1 P01

Bimlead have prepared a Autodesk Revit® & Graphisoft ArchiCAD® project template with in-built parameters related to the ISO drawing numbering convention. We have provided a example A1 title block for both the software and have included the A1 titleblock as well as shared parameter file for Revit. The users can add other titleblock templates such as A2 & A3 as required by modifying the A1 template provided.


Below is a description of how the Field information within each software is driven by the parameters. Status and Revision codes are driven by metadata but can be easily incorporated into titleblocks if needed. The templates can be downloaded from our Tools section above (requires email input). If you have any comments, please feel free to let us know in the comments section below or email us using the contact form, we will be happy to help.

A question was asked in a BIM forum: "We like to show the building elevation with 2 or 3 different color options for the client to choose from. Elevations do not change, just the paint is changing. I know I can copy the building over 3 times and give each one different colors, but these are massive buildings and I am hoping to avoid that. Also, I don't think we can use the "design Option" for the pain only. How would you offer multiple looks for the same building? Any suggestion would be appreciated." The simplest way to achieve this is by applying view filters to each of the duplicated elevations and then applying various colour / hatch options to duplicated elevations in the vg settings. For example - see above image showing four colour options for the same elevation. I have duplicated the south elevation four times, applied the same 3 view filters to each elevation picking out the family types that I needed in the options.
