Intelligent specification, in the cloud

Over recent years, using the cloud has allowed me to connect applications and data together inside and outside work.

Looking at examples from outside work, it's so easy to embed a youtube video within Facebook - or transfer the data from a fun run from Garmin to Strava - or buy a book on the Amazon App and then see it on my Kindle. The cloud has revolutionized the way we interact in our daily lives.

When working on NBS Chorus, as a cloud based tool we expected that this would transform the way the industry interacted with specifications. We were aware of some immediate transformational benefits such as (1) functioning on other devices other than PCs (Mac, Tablet, Chromebook etc...), (2) the ease at which contributors can be added to a project and (3) the end to problematic installation of software and content on local machines/networks.

However, now that Chorus has been released - it's great to see some additional cloud benefits.

A special shout out here to Rob Jackson from Bond Bryan Digital (plug below - check out their services) for tweeting a few of the workflows he has managed to get Chorus linking to open data methodologies.

UK BIM Alliance - BS EN ISO 19650 Guidance

A free guide to the BS EN ISO 19650 series is now available:

UK BIM Alliance - BS EN ISO 19650 Guidance
This guide has been produced by UK BIM Alliance in association with Centre for Digital Built Britain (CDBB) and BSI.

The guide sets the scene of why digital information management is important and what the rationale for the 19650 series was. It then looks at the legal and security implications and in particular signposts the CIC BIM Protocol and the PAS 1192-5 standard.

The second half of the publication looks at the information delivery cycle and provides some practical examples.

It's good to see references to NBS resources. In particular:

  • Secton 6.5 looking level of information need. The guide references the work in progress here at a CEN level and also the free-to-use LOD and LOI guides on the NBS BIM Toolkit.
  • Section 6.6 gives a good overview on how to classify information and uses examples from Uniclass 2015.
  • Finally, Section 7 looks at the National Annex to BS EN ISO 19650-2 and provides guidance on the naming of information containers and associated metadata with respect to information delivery using common data environments. I blogged on a similar subject earlier in the year and NBS colleagues have been in discussions with the UK BIM Alliance team on this topic.

With respect to the National Annex, expect further alignment between the Form of Information and Roles Tables in Uniclass in the next month or two.

So - a good publication - great to see that support such as this is being produced for free for the industry and well done to those that have given up their time to contribute.

BIM - God is in the Specification

One of the most engaging speakers at BIM Show Live 2019 this year was James Woudhuysen. James is an author and speaker on technology trends and forecasting.
James Woudhuysen - BIM Show Live 2019
He challenged the tech-loving delegates about some of their statements in a fun and engaging way. Are we really experiencing 'exponential' disruption? developing 'seamless' systems? is AI really 'everywhere'? are the robots coming?
Myth busting
He then moved onto BIM. There was a clear message here - with respect to structured data and information collaboration through the timeline - it's about the specification.
When thinking BIM - think specification
These are key messages that we have been pushing for years at NBS as we integrate our developments into the wider BIM environment.

What quality of product is being specified. what quality of execution is required and what quality of documentation is required to prove the specification has been followed.
Specify the supplier and how it will be tested
The blue, green and red Powerpoint with sunlight on may not have been clear, but the message certainly was.

BS EN ISO 19650 and Uniclass

BS EN ISO 19650 parts 1 and 2 have now been out for a few weeks and there has been a lot of discussion on social media on how to make best use of the Uniclass tables when managing information for building and civil engineering work.

This blog post covers my thoughts from recent discussions internally, on social media and also a few web meetings with some members of UK BIM Alliance. Comments are very much appreciated and will help shape more formal UK BIM Alliance guidance being published later in the year.

BS EN ISO 19650-1:2018
The concepts and principles outlined in part 1, when considering information quality, state that classification '...should be in accordance with the principles in ISO 12006-2'. The UK implementation of ISO 12006-2 is Uniclass (Uniclass 2015). This is a free-to-use classification made available to industry at:

BS EN ISO 19650-2:2018
Part 2 lists ISO 12006-2 as one of the normative references in the introduction.

Clause 5.1.7 then reinforces that all information containers shall have an attribute for classification (in accordance with the framework defined in ISO 12006-2) when placed in the project's common data environment.

Part 1 makes it clear that an information container could be both structured and unstructured. 'Structured information containers include geometrical models, schedules and databases. Unstructured information containers include documentation, video clips and sound recordings.'

So to be clear, when delivering 'BIM to ISO 19650' the scope is so much more than a 3D model of a building. The information that is to be managed stretches to an information container that is a sound recording of a meeting reviewing feedback from a previous highways project.

The UK National Annex provides further guidance and this is mainly grouped into field codification of the ID of the information container and additional metadata.

Classification metadata
This should define what information is in the information container. To give some examples at various stages of a project.

  • A business case at the Strategic Definition Stage - PM_50_30_10 - Business Case
  • A BEP at the Preparation and Brief Stage - PM_40_60_64 - Pre-contract BIM execution Plan
  • An early version of the Security Strategy at the Concept Design Stage - PM_80_50_80 -Security strategy
  • A work package containing drawings and specifications for all designed security systems - Ss_75_40 - Security systems
  • An asset data template for an infrared digital camera provided by a client in the supporting information - Pr_60_75_86_41 - Infra-red cameras

So codes from the appropriate Uniclass table can be used to define what is contained in the information container.

The big advantage of providing this level of granularity is being able to digitally query large information sets in modern common data environments and organisation's other data repositories.

Field codification
The field codification in the UK National Annex is a method of giving each information container on a project a Unique ID. The best analogy for me here is with a car registration plate. Make it unique and recognisable in the shortest way possible.
In the above example, this car was registered in Birmingham (BD) in the second part of 2001 (51).

Now, compare this now to the field codification rules in the UK Annex to BS EN 19650-2.
Just like a registration plate, the UK National Annex recommends that very short codes are used to create this unique ID. For example, the role requires a 1 or 2 digit code - so Architect is suggested to be shortened to 'A'. There is also a note to say that in the Project Information Standard additional codes can be specified for roles outside of the Annex. For example, 'CR' for Client Advisor. This is just like using 'BD' to indicate Birmingham.

So, what does this mean for Uniclass and these fields?

It would seem sensible for the Uniclass classifications to align and for each of these classifications to have a short code. I'd also suggest that the leading Common Data Environment's would build these unique IDs from metadata provided at upload (we shouldn't really be relying on renaming files in Windows Explorer). The Form of Information table seems to align nicely with the 'Type' (3D model, video, sound recording etc..), the Roles table aligns with the Role (Client, Contractor, Architect...).

To look at five earlier examples, this is how I'd expect them to appear in a Common Data Envrionment when working to BS EN 19650-2. The short codes in the Annex (and additional Project Information Standard codes) are linked to the Uniclass classification.

Unique ID nice and short - additional metadata giving further information
Quickly querying to filter by similar items (the power of classification)
As I said at the start of the post. This is my initial interpretation of how the 19650 series can be used with Uniclass. Please drop comments through and this will hopefully feed into more formal guidance that is reviewed by a number of people.

I'd be also very keen to see how other countries around the world develop their National Annexes to give guidance on this. Please drop me an email if you have any insight into this.

Edit 1:
The UK Foreword to BS EN ISO 13567-2:2017 Technical product documentation - organization and naming of layers for CAD. Concepts, format and codes used in construction documentation (ISO 13567-2:2017) covers guidance on layer naming and Uniclass. I had blogged on this one too - and the Dan Rossiter took ownership in terms of drafting the words for B/555.

The NBS Construction Technology Report 2019

We recently published our NBS Construction Technology Report. This was a survey of over 500 construction professionals, mainly based in the UK. This was a healthy sample size based on the number of construction professionals in the UK.

The report is a mixture of an analysis of the survey and also some opinion pieces from small, medium and large sized organisations that are pushing the boundaries with technology in the industry. We also received a thought-leadership piece from Microsoft (rather than single out one of the construction tech firms that more traditionally lead the design tech or construction tech spaces).

Some snippets below in this blog post. Link to download the full report for free at the bottom of the post.

One final point to address, we know that technology is not the only of topic of importance in the industry. We have previously published surveys into sustainability, contracts+law, specification and BIM - but we thought that technology is such a game changer, that it deserved a report of its own.

The report is opened with an introduction from NBS Chief Exec Richard Waterhouse

Opinion piece from Ben Highfield Microsoft looking at how leaders can adopt digital technologies to achieve their goals

An introduction to the ISO 19650 series

Last Friday, Paul Shillcock, one of the authors of the 19650 series of international BIM standards presented to a packed lecture theatre at NBS.

Most people in the room were familiar with 'UK Level 2 BIM'. So Paul focused on some of the differences between the 1192 series of UK standards and how the team had worked with the international community to ensure a common process could be defined for BIM around the world.
Paul - presenting the 1192 to 19650 journey
A nice summary was given at the end detailing how the 19650 series takes the 'best bits' from 1192, compromises with the international community and then allows each country to add a National Annex to reflect local practices.
Paul's summary points
The 19650 series can be purchased from the BSI website. Alternatively, those companies that subscribe to IHS Markit-NBS Construction Information Service can download the standards and transitional guidance from CIS:

Download BS EN 19650 standards now from Construction Information Service
The presentation was captured on video. Watch this below:
(Also, you can download the presentation from the NBS website)

It was good to spend some time with Paul discussing the format for exchange information requirements (EIRs) following the presentation. Looking at the essential items for an EIR schedule as defined by BS EN ISO 19650-2 it was fun to look at what this would have been for the presentation that Paul provided as part of the event... ;)
19650 - EIRs with a new focus on information requirements
The presentation itself was of course named following the rules for information containers in the UK National Annex:

CR | C01.01 | XX

Following Paul's presentation, I also gave a 15 minute presentation on Uniclass. This can also be downloaded from the NBS website and viewed in the above video.

The relevance, of course, is that Uniclass 2015 is listed in the UK National Annex as the classification system for Information Management on BIM projects.
UK Annex and Uniclass
My presentation gave (1) an introduction to Uniclass, (2) some industry examples of large clients using this on projects and (3) examples of how NBS have now embedded this into the National BIM Library and the NBS Chorus specification tool.

The Uniclass classifications can be accessed for free at:

As a final word, well done to Paul, David Churcher, Anne Kemp and Steph Kosandiak for all of their hard work in working with the international community to publish these standards.

An international classification for the built environment

I was presenting to an international delegation recently and wanted a slide sequence to question whether a single universal classification system was possible for the built environment.

I then asked the Twitter community what they thought...
Twitter Poll
Essentially, would it be possible to have a single code to represent each 'object' in the built environment and then have international translations for each of these codes?
With increasing interest in Uniclass around the world, I wonder whether this will happen one day.
