Abdul Shaikh • 1 December 2020

About BS EN ISO 19650-1:2018

ISO 19650 is a international standard produced to remove barriers to collaborative working. Part 1 of this standard; ISO 19650-1 Organization of information about construction works - Information management using building information modelling. 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.

Let’s be honest—when it comes to Point Cloud to BIM, most teams default straight to Autodesk Revit. Not because it’s always the best tool for the job, but because it’s the most familiar. The problem? Point cloud data doesn’t behave the way traditional BIM tools expect it to. And that’s exactly where BricsCAD starts to make a lot more sense. Before going any further—this isn’t a paid promotion, and I’m not affiliated with BricsCAD. This is based purely on project experience. BIM Software Wasn’t Built for Reality Most BIM tools—especially Autodesk Revit—are built around idealised geometry: Straight walls Perfect alignments Clean, predictable inputs Point clouds are the opposite. They’re messy. Incomplete. Full of inconsistencies. And if you’ve worked on refurbishment or existing buildings, you’ll know—that’s reality. Trying to force that into rigid parametric rules is where time gets lost. BricsCAD Doesn’t Fight the Data What stands out immediately with BricsCAD is that it doesn’t try to “correct” reality—it lets you work with it. You’re not forced into predefined object behaviour from the start. You can: Interpret geometry naturally Model irregular conditions without workarounds Apply structure and data after you’ve captured the shape That shift alone makes a huge difference on scan-heavy projects. The Flexibility Gap Is Real Here’s the part most people don’t talk about: In tools like Autodesk Revit, you often spend more time fighting the software than modelling the building—especially when the geometry isn’t textbook-perfect. With BricsCAD, the process feels much closer to how people actually think when interpreting a scan: Sketch it Adjust it Refine it Then classify it It’s a small shift in workflow, but a big shift in efficiency. AI That Actually Helps (Not Just Marketing) There’s a lot of noise around “AI in BIM,” but in BricsCAD, some of it is genuinely useful. Plane detection and geometry recognition tools can take a lot of the repetition out of modelling—especially on large datasets. It’s not magic, and it won’t replace good judgement—but it does speed up the boring parts. Direct Modelling Is Underrated One of the biggest advantages—and one that’s often overlooked—is direct modelling. Being able to push, pull, and reshape geometry without rebuilding families or breaking constraints is incredibly valuable when working from scan data. In comparison, more parametric-heavy tools like Autodesk Revit can feel restrictive when you just need to respond quickly to what’s in front of you. It’s Not About Replacing Revit To be clear—this isn’t about saying Autodesk Revit is “bad.” It’s not. It’s still the industry standard for a reason. But Point Cloud to BIM is a very specific use case—and it exposes some of the limitations of traditional BIM thinking. BricsCAD fills that gap surprisingly well. Final Thought If you’re working on: Existing buildings Refurbishment projects Heritage assets Or anything driven by scan data …it’s worth questioning whether your current tool is actually helping—or just familiar. Because in this space, flexibility beats convention more often than people admit. Need Help with Scan-to-BIM? At Bimlead, I help teams implement practical, efficient BIM workflows—including point cloud modelling, automation, and ISO 19650 alignment.

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.
