@daniel-blockcp-catapult-org-uk, @CatherineCondie, @Melissa-Zanocco-CommunityCouncil I wondered if this could be used to help revise/streamline the templates used to capture use cases?

Happy New Year everyone.

I’m pleased to report a new ISO Standard, PD ISO/IEC TR 30194:2024 has been published. This ISO describes best practices for use cases, with the objective to improve the consistency of content across different use…

Hi all, doing my commenting on standards I found a strong reference to “semiotic triangles” within the ISO work for digital twins.  In essence, it’s a concept that describes the relationship between what you are “twinning”, its representation, and its semantic meaning.  

For example, semiotic triangles can be used to determine whether it is…

New standards are being developed in the field of Digital Twin. The international technical committee is currently defining concepts and terminology and researching use cases. The aim is to deal with horizontal issues impacting on digital twin in any sector, so we would welcome representation from all types of industry.

Hi all,  I received this Digital Construction Week article today about some Procore research and thought it included some interesting conclusions.

Firstly, thank you to everyone who joined the concepts and principles standards workshop on the 11th of February.  With 70+ attendees and a wealth of engagement, I feel that we managed to make some real progress in establishing the DT Hub community’s views on the future BSI Flex standard.  As mentioned during the workshop, the slide deck p…

Hi @tombartley, thank you for this.  I’m glad you support the general premise, and I agree aspects like Applications (Uses) and Observable elements are important.  The goal of the workshop on the 11th is to test/challenge these headings with the community so Benefits may fall out.  As I mentioned in the previous post, I’ve (shamelessly) taken th…

As part of my last post Consolidating Concepts: Scope, I discussed a potential structure that a concepts and principles standard related to digital twin could adopt.  In this post, I’ll consider how this structure aligns to the Gemini Principles.  I’d greatly appreciate your views as to whether I’ve gotten this right! 

Using ISO/DIS 23247…

Hi all,

Today I discovered that we (Wales) have begun to nationalize our rail service with all Transport for Wales routes coming under govt control. 

Fab, thank you for posting this @Casey. 

Interestingly, I listened to a Digital Twin Consortium webinar last night (sorry for cheating on the DTHub!).  The narrative being used was around how BIM had failed to make real change and this (DTs) was almost the next attempt.  As @HenryFT mentions above, we don’t want digital twins to be…

Hi @Tom Henderson, thank you for video.  Can I ask what is the relationship between the TechUK digital twin work group and the DFTG and/or DTHub?

 What’s your view on representing wayleaves and easements specifically?

Hi @Neil, I’m asking while I watch (apologies if it is covered mid-vdieo).  Does NUAR include the capture information related to any associated easements and if so, how is it captured?

Hi @Miranda, this might be an unfair question (sorry) but how does the NDT programme plan to quantify what information is needed from stakeholders and support them in maintaining it. 

In your bridge example there is a cost (time/money/effort) to maintain a conforming dataset that may not support asset owner use cases.  In these inst…

Hi @Miranda, thank you for the video.  An idea dawned on me as I was watching.  You mention the London Underground working in isolation successfully as well as the greater benefit that can be realized through their connectivity.  Do you think that we may end up with a twin classification such as:

We ran a webinar on third theme for the DT Hub, “Pathway to value” on 25th June 2020.

We also began to look at proposed activities for the theme and related priorities for…

Following input from DT Hub members into a community-driven document, we have proceeded to reduce the number of use cases identified during the Pathway to Value Workshop from 28 down to 12:

4. Occupant/User Management
5. Environmental Management

It feels like the established use cases for Digital Twins are usually twins for ‘things’ rather than ‘systems’.

During our research activities within the DT Hub, several barriers relating to the use of digital twins were identified.  This blog post, which looks at digital skills, reflects on skill as a barriers and considers related issues so that we can discuss how they may be addressed.

We are now coming to the end of our live discussion but we will keep this space open and available until the end of the day in case you have further thoughts or questions. We will continue to monitor the discussion during that time, but on a…

Hi @Neil, you mentioned that the glossary is a part of the commons work-steam.  Does this mean that terminological entries hosted within the Glossary will be used by the other work streams?  For example, could an entry accepted within the Glossary end up in a future CDBB report?

Morning all,

Following yesterday’s excellent Digital Twin talk with imec and @Tanguy, my cogs started to whirl and, in conversation with @Simon (thanks Simon!), a visual fell out.

Another question – for @Tanguy and all.

What are the most valuable/attractive use cases for digital twins in cities?

Hi Tanguy, 
Thank you for the video, very interesting.  You mentioned the need to manage the latency between the changes to the physical asset and its representation digitally.  What I wanted to ask if there are two distinct latencies:
