BIM Compliance – Where are we with BIM Standards?

At Michael Gallie & Partners, our emphasis is on ensuring clients leverage BIM to its fullest. We champion a unified approach, fostering synergy among design teams right from a project’s inception, eliminating potential errors down the line.


The Rise and Integration of BIM in Modern Construction

The Government’s 2016 mandate for all its building ventures to achieve Level 2 BIM compliance marked a significant shift. This mandate thrust Building Information Modelling into the mainstream of the AEC sector, making it a cornerstone for various building ventures. With time, as the industry internalised lessons and refined its strategies, BIM standards have seen progressive evolutions, promoting enhanced collaboration in projects.


BIM Standards: A Glimpse into the Current Landscape

When diving into prevalent BIM standards, the PAS 1192 series, unveiled by BSI in 2013, is a frontrunner. Tailored to the modus operandi of the UK’s AEC sector, this series stands as a testament to the industry’s commitment to BIM. However, its UK-centric design occasionally hit issues when applied internationally.

Addressing this, the AEC world welcomed the BS EN ISO 19650 BIM standards in early 2019. Considered an augmented version of the PAS 1192, the new standard broadens its horizon to cater to a global audience. By offering ample room for regional-specific tweaks, BS EN ISO 19650 promises to bridge the gaps left by its predecessor. While its adoption rate in the UK is currently moderate, its relevance and influence are poised to escalate, potentially overshadowing the PAS/BS 1192 series.

On the classification front, Uniclass 2015 reigns supreme in the UK AEC sector. With consistent upskilling and training, coupled with the palpable financial advantages BIM offers in design and construction, it’s evident that BIM’s imprint on the AEC landscape will only deepen.



The dynamic world of Building Information Modelling is a testament to the AEC industry’s relentless pursuit of excellence. With evolving standards and an industry eager to adapt, BIM is not just a tool but the future of design, collaboration, and construction.

1. Why did the Government introduce a BIM mandate in 2016?

To standardise construction projects, ensuring efficiency and collaboration throughout the process.

2. How do the PAS 1192 series and the BS EN ISO 19650 BIM standards differ?

While the PAS 1192 is tailored for the UK AEC industry, the BS EN ISO 19650 is designed with a global perspective, allowing for regional-specific adaptations.

3. Is the PAS 1192 series obsolete now?

While it remains relevant, the advent of more inclusive standards like BS EN ISO 19650 suggests a possible shift in preference in the future.

4. What is Uniclass 2015?

It’s a classification standard primarily used in the UK AEC sector for BIM projects.

5. Why is collaboration emphasised so much in BIM projects?

Collaboration ensures seamless integration of diverse expertise, resulting in efficient and error-free project execution.
