Autodesk Tandem, the cloud-based digital twin platform, is evolving at an impressive pace. Unusually, much of its development is happening out in the open, with regular monthly or quarterly feature preview updates and open Q&A sessions. Martyn Day takes a closer look at what’s new

Project Tandem, as it used be known, was initiated in February 2020, previewed at Autodesk University 2020, and released for public beta in 2021. Four years on, there are still significant layers of technology being added to the product, now focussing on higher levels of functionality beyond dashboards and connecting to IoT sensors, adding systems knowledge, support for timeline events and upgrades to fundamentals such as visualisation quality.

Tandem development seems to have followed a unique path, maintaining its incubator-like status, with Autodesk placing a significant bet on the future size of an embryonic market.

For those following the development of Tandem the one thing that comes across crystal clear, is that creating a digital twin of even a single building — model generation, tagging and sorting assets, assigning subsystems, connecting to IoT, and building dashboards — is a huge task that requires ongoing maintenance of that data.

It’s not really ‘just an output of BIM’ which many might feel is a natural follow on. It has the capability to go way beyond the scope of what is normally called Facilities Management (FM), which has mainly been carried out with 2D drawings.

The quantitative benefit of building a digital twin requires dedication, investment and an adoption of twins as a core business strategy. For large facilities, like airports, universities, hospitals – anything with significant operating expenses – this should be a ‘no brainer’ but as with any investment the owner/operator has to pay upfront to build the twin, to realise the benefits in the long tail, measured in years and decades. This, to me, makes the digital twins market not a volume product play.


Autodesk Tandem


Tandem evolution

My first observation is that the visual quality of Tandem has really gone up a notch, or three. Tandem is partially developed using Autodesk’s Forge components (now called Autodesk Platform Services). The model viewer front end came from the Forge viewer, which to be honest was blocky and a bit crappy-looking, in a 1990s computer graphics kind of way. The updated display brings up the rendering quality and everything looks sharper. The models look great and the colour feedback when displaying in-model data is fantastic. It’s amazing that this makes such a difference, but it brings the graphics in to the 21st century. Tandem looks good.

As Tandem has added more layers of functionality the interface tool palettes have grown. The interface is still being refined, and Autodesk is now adopting the approach of offering different UIs to cater to different user personas, such as operators who might be more familiar with 2D floor plans than 3D.

Other features that have been added include the ability to use labels or floor plans to isolate them in the display, auto views to simplify navigation, asset property cards (which can appear in view, as opposed to bringing up the large party panel) and thresholds, which can be set to fire off alerts when unexpected behaviour is identified. Users can now create groups of assets and allocate them to concepts such as ‘by room’. Spaces can now also be drawn directly in Tandem.

Speed is also improved. As Tandem is database centric, not file based, it enables dynamic loading of geometry and data, leading to fast performance even with complex models. It also facilitates the ability to retain all historical data and easily integrate new data sources as the product grows. This is the way all design-related software will run. Tandem benefits from being conceived in this modern cloud era.

That said, development of Tandem has moved beyond simply collecting, filtering, tagging and visualising data to providing actionable insights and recommendations. From talking with Bob Bray, vice president and general manager of Autodesk Tandem and Tim Kelly, head of Tandem product strategy, the next big step for Tandem is to analyse the rich data collected to identify issues and suggest optimisations. These proactive insights would include potential cost savings and carbon footprint reduction through intelligent HVAC management based on actual occupancy data.

Systems tracing

Having dumb geometry in dumb spaces was pretty much the full extent of traditional CAFM. Digital twins can and should be way smarter. The systems tracing capability in Tandem simplifies the understanding of all the complex building systems and their spatial relationships, aiding operations, maintenance, and troubleshooting. By clicking on building system elements, you can see the connections between different elements within a building’s systems and see how networks of branches and zones relate to the physical spaces they serve and identify where critical components are located within the space. This means if something goes wrong, should that be discovered via IoT or reported by an occupant, systems tracing allows the issue to be pinpointed down to a specific level and room. Users can select a component like an air supply and then trace its connection down though subsystems to the spaces it serves.

Tandem is a cloud-based conduit, pooling information from multiple sources which is then refined by each user to give them insight into layers of spatial and telemetric data

Building in this connection between components to make a ‘system’, used to be a pretty manual process. Now, Tandem can automatically map the relationships between spaces and systems and use them for analysis to identify the root cause of problems. Timelines Data is valuable and BMS (Building Management Systems) and IoT sensors generate the building equivalent of an ‘ECG’ every couple of seconds. The historical, as well as the live data is incredibly valuable. Timelines in Tandem display this historic sensor data in a visual context. Kelly demonstrated an animated heatmap overlaid on the building model showing how temperature values fluctuate across a facility. It’s now possible to navigate back and forth through a defined period, either stepping through specific points or via animation, seeing changes to assets and spaces.

While the current implementation focuses on visualising historic data, Kelly mentioned the future possibility of the timeline being used to load or hide geometry based on changes over time, reflecting renovations or other physical alterations to the building.

Bray added that Tandem never deletes anything, implying that the historical data required for the timeline functionality is automatically retained within the system. This allows users to access and analyse past performance and conditions within the building at any point in the future, should that become a need.

Asset monitoring

Asset monitoring dashboards in Tandem are designed to provide users with a centralised view for monitoring the performance and status of their key assets. This feature, which is now in beta, aims to help operators identify issues and prioritise their actions. They will be customisable, and users can create dashboards to monitor the specific assets they care about This allows for a tailored overview of the most critical equipment and systems within their facility.

The dashboards will likely allow users to establish KPIs and tolerance thresholds for their assets. By setting these parameters, the system can accurately measure asset performance and identify when an asset is operating outside of expected or acceptable ranges with visual feedback of assets out of optimal performance.

Assets that are consistently operating out of tolerance or experiencing recurring issues can be grouped to aid focus e.g. by level, room, manufacturer. With this in mind, Tandem also has a ‘trend analysis’ capability, allowing users to identify potential future problems based on current performance patterns. The goal of these asset monitoring dashboards is to help drive preventative maintenance and planning for equipment replacement.

Tandem Connect

Digital Twin creation and connectivity to live information means there is a big integration story to tell and it’s different on nearly every implementation. Tandem is a cloud-based conduit, pooling information from multiple sources which is then refined by each user to give them insight into layers of spatial and telemetric data. To do that, Autodesk needed to have integration tools to tap into, or export out to, the established systems, should that be CAFM, IoT, BMS, BIM, CAD, databases etc.

Tandem Connect is designed to simplify that process and comes with prepacked integration solutions for a broad range of commonly used BMS. IoT and asset management tools. This is not to be confused with other developments such as Tandem APIs or SDKs.


Autodesk Tandem


The application was acquired and so has a different style of UI to other Autodesk products. Using a graphical front end, integrations can be initially plug and play, such as connecting to Microsoft Azure, through a graph interface. The core idea behind this is to ‘democratise the development of visual twins’ and not require a software engineer to get involved. However more esoteric connections may require some element of coding. Bray admitted there was significant ‘opportunity for consultancy’ that arises from the whole connectivity piece of the pie and that a few large system integrators were already talking with Autodesk about that opportunity.

Bray explained that Tandem Connect enables not only data inflow and outflow but also ‘workflow automation and data manipulation’. He gave an example where HVAC settings could be read into Tandem Connect, and a comfort index could be written, which was demonstrated at Autodesk University 2024.

Product roadmap

Autodesk keeps a product roadmap which has been pretty accurate to show the development of travel, given the regular video updates.

Two of the more interesting capabilities in development are portfolio optimisation and the development of more SDK options, plus the possibility of future integration of applications. Portfolio optimisation will allow users to view data of multiple facilities in one central location and should provide analytics to predict future events with suggested actions for streamlining operations.

Beyond the current Rest API (Now), Autodesk is developing a full JavaScript Tandem SDK to build custom applications that leverage Tandem’s logic and visual interactivity. In the long-term, Autodesk says it will possibly enable extensions for developers to include functionality within the Tandem application itself.

Conclusion

Tandem development continues relentlessly. The capabilities that are being added now are starting to get into the high value category. While refinements are always being added to the creation and filtering, once the data is in and tagged and intelligently put into systems, it’s then about deep integration, alerts for out of nominal operation at a granular level, historical analysis of systems, spaces and rooms, all with easy visual feedback and the potential for yet more data analysis and intelligence.

Bray uses a digital twin maturity model to outline the key stages of development needed to realise the full potential of digital twin technology. It starts with building a Descriptive Twin (as-built replica), then Informative Twin (granular operational data), then Predictive Twin (enabling predictive analytics), Comprehensive Twin (what-if simulation) and Autonomous Twin (self-tuning facilities).

At the moment, Tandem is crossing from Informative to Predictive, but the stated intent for higher level functionality is there. However the warning is, your digital twin is only ever as good as the quality of the data you have input.

Some of the early users of Tandem are now being highlighted by the company. In a recent webinar, Brendan Dillon, director of digital facilities & infrastructure, Denver International Airport gave a deep dive into how they integrated Maximo with Tandem to monitor facility operations.

Tandem is an Autodesk outlier. It’s not a volume product and it’s not something that Autodesk’s channel can easily sell. It’s an investment in a product development that is quite unusual at the company. It doesn’t necessarily map to the way Autodesk currently operates as, from my perspective, it’s really a consultancy sale, to a relatively small number of asset owners – unlike Bentley Systems, whose digital twin offerings often operate at national scale across sectors like road and rail. The good news is that Autodesk has a lot of customers, and they will be self-selecting potential Tandem customers, knowing they need to implement a digital twin strategy and probably have a good understanding of the arduous journey that may be. The Tandem team is trying to make that as easy as possible and clearly developing it out in the open brings a level of interaction with customers that in these days is to be commended.

Meanwhile, with its acquisition of niche products like Innovyze for hydraulic modelling, there are some indications that Autodesk is perhaps looking to cater to more involved engagements with big facility owners, and I see Tandem as falling into that category at the moment, while the broader twins market has still yet to be clearly identified.

AEC Magazine caught up with Rob Charlton, CEO of Newcastle’s Space Group to talk about digital twin adoption and advances. Twinview, created by the the company’s BIM Technologies spin off, is one of the most mature solutions on the market today and now has global customers

It’s tough being one of the first to enter a market but for Space, one of the country’s most BIM-centric architectural practices, it was a case of needs must. In 2016, its BIM consultancy spin-off, BIM Technologies, identified a need for its clients to be able to access their model data without the need for expensive software or hardware. Development started and this eventually became Twinview, launched in 2019.

Space Group is a practicing architecture firm, a BIM software developer, a services supplier, a BIM components / objects library creator and distributor. So, not only does it develop BIM software, it also uses the software in its own practice, as well as sell its solutions and services to other firms.

Selling twins

In previous conversations with CEO Rob Charlton on the market’s appetite for digital twins, he has been frank in the difficulty in getting buy in from fellow architects, developers and even owner operators. The customers who got into twins early were firms that owned portfolios of buildings which were sold as eco-grade investments.

Charlton acknowledges that he always expected it to be a long-term endeavour, “We started this development knowing it was it was a five year plus journey to any level of maturity or even awareness”. He draws a parallel to the adoption of BIM, recalling that even though Space bought its first license of Revit around 2001, it didn’t gain significant traction until around 2011, and even then, this was largely due to UK BIM mandates.

The early digital twin market development was a ‘slow burn’. Charlton contrasts BIM Technologies’ patient, self-funded approach with companies that seek large VC funding, arguing that “ the market will move at the level it’s ready for”.

He explains that the good news is that over the last year, there has been an increase in awareness of the value
of digital twins, particularly in the last six months.

This awareness is seen in the fact that clients are now putting out Requests for Proposals (RFPs) for digital twin solutions. For Charlton, this is a fundamental difference compared to the past, where they would have to approach firms to explain the benefits of digital twins. Now, the clients themselves have made the decision that they want a digital twin and are seeking proposals from providers.

Priorities and needs

There’s a lot of talk about digital twins but very little talk concerning the actual benefits of investing in building them. Charlton explains a lot of twin clients are increasingly interested in reducing carbon in buildings, whether that be in embodied or operational and compliance and safety. “It’s an area that Space is particularly passionate about but there is an inconsistency in how embodied carbon reviews and measurements are conducted,” he says.
Customer access to operational data is also important, explains Charlton, “Clients want to gain insights into how their buildings are actually performing in real time.”

He also notes that the facilities and the integration with facilities management is equally important, to streamline maintenance, manage issues, and improve overall building operations.

Clients value the ability to have “access to their information in one place” adds Charlton. And here, the cloud is the perfect solution to deliver a unified platform which consolidates models, and documents related to building assets.

Twinview clients are especially interested in owning their own data. Charlton gives the example of a New Zealand archive project, explaining that the client was particularly interested in having Twinview to maintain independence when using a subcontractor or external service provider, which might come and go over the project lifetime.

Back in the UK, Twinview is being used in conjunction with ‘desk sensors’ on an NHS project to optimise space and potentially avoid unnecessary capital expenditure. Charlton explains that the client was finding the digital twin useful for “analysis on how the space is used” because they were seeking to validate or challenge space needs assessments by consultants.

Increasingly, contractual obligations include performance data. For one of Space’s school clients, the DFA Woodman Academy, there’s a contractual obligation to provide energy performance data at month, three months and 12-months. Digital twin technology facilitated the compliance goal within the performance-based contract. The IoT sensors also identified high levels of CO2 in the classrooms, prompting an investigation into the cause.
Twinview goes beyond the traditional digital twin model for operations and has been used to connect residents to live building information. On a residential project, tenants access the Twinview data on their mobile phones to see energy levels in the buildings, temperatures and CO2, all through their own app.

Artificial Intelligence

Everyone is talking about AI, and Twinview now features a ChatGPT-like front end. This enables plain language search within the digital twin, both at an asset level and with regards to performance data. Charlton explains that while the AI in Twinview has a ‘ChatGPT-like interface’, it is not directly ChatGPT, although it does connect to it. He explains that Twinview developed its own system. This is possibly due to the commercial costs associated with using ChatGPT for continuous queries. The AI in Twinview accesses all building information, including the model, operational data, and tickets, which are stored in a single bucket on AWS. Looking to the future, Charlton mentions that the next stage of AI development for Twinview will be focused on prediction and learning. This includes the ability to generate reports automatically (e.g. weekly on average CO2 levels), predict future energy usage, and suggest ways to improve building performance. A key differentiator for AI in Twinview in the future, will be in its capacity to understand correlations between disparate datasets that are often siloed, such as occupancy data, fire analysis, and energy consumption. By applying a GPT-like technology over this connected data, the aim is to uncover new insights and solutions.

Development Journey

From a slow burn start, despite being a relatively small UK business and competing with big software firms with
deep pockets, Charlton told us that Twinview had already won international clients and is currently being
shortlisted for other significant international projects, including one on the west coast of America, against international competition.

New portfolio options focus on reality data for AEC projects and industrial and manufacturing sites

Cintoo is adding new portfolio options to its Cintoo platform – the BIM and Twin Editions.

The Cintoo platform, which is focused on reality data, allows users to upload and stream huge 3D data files from any desktop or laptop via a web browser. Users can compare reality data to their BIM and CAD models or scans to scans for project collaboration and optimisation.

The new BIM Edition is designed for AEC-centric workflows and includes features such as progress monitoring and issue tracking for performing analysis and to help eliminate risk.

The Twin Edition of the Cintoo platform is aimed at huge industrial and manufacturing sites to help improve asset visibility, digital twin management, and optimise facility maintenance and rework.

Cintoo has also introduced a new look and feel to the Cintoo platform. According to the company, it’s now easier to access key tools and the updated head ribbon maximises project space, as panels have been moved to the menu on the right-hand side.

Geo whiz: Bentley acquires Cesium https://aecmag.com/geospatial/geo-whiz-bentley-to-acquire-cesium/ https://aecmag.com/geospatial/geo-whiz-bentley-to-acquire-cesium/#disqus_thread Sun, 22 Sep 2024 06:00:15 +0000 https://aecmag.com/?p=21552 We explore the surprise deal that promises to bring the worlds of digital twins and geospatial closer together

The post Geo whiz: Bentley acquires Cesium appeared first on AEC Magazine.

]]>
In mid-September, out of the blue, Bentley Systems announced it had acquired Cesium, an industry cherished 3D geospatial platform with an ecosystem of open standards, including Cesium.JS and 3D Tile technology. Martyn Day talked with Patrick Cozzi, previously of Cesium, and Julien Moutte, Bentley Systems CTO, to learn more about the deal that promises to bring the worlds of digital twins and geospatial closer together

It’s rare that a piece of industry news arrives in my inbox and prompts me to do a double-take. But that’s exactly what happened on 6 September, with the news that Bentley Systems had acquired Cesium.

Bentley Systems is the infrastructure giant in the AECO space and is currently undergoing a changing of the guard as the brothers who founded the company take a step back and get a new executive team installed.

That can be a distracting process for any organisation. However, new Bentley CEO Nicholas Cumins has made the choice to forge ahead with an industry significant acquisition, probably the most impactful since Google sold SketchUp to Trimble.

Because Bentley has always strongly focused on infrastructure, geospatial has played an important part in the data frameworks that its solutions provide. Decades ago, the company was the first CAD software firm to integrate a world-based coordinate system in its file format, because big infrastructure projects are always located somewhere and can span thousands of kilometres.

Bentley has had agreements with Esri, in addition to offering its own mapping and cadastre-driven tools. However, for the last few years, it has obsessively developed and also acquired technologies relating to 4D construction, reality capture, digital twin and asset management.

Bentley Systems is not the only AEC-focused software firm to understand the importance of geospatial. When Andrew Anagnost took the CEO job at Autodesk in 2017, he didn’t waste time in forging a partnership with ESRI and starting to back-fill the company’s BIM and civils products with GIS integration. Autodesk also actively chased Bentley Systems’ Department of Transport clients and acquired Innovyze in 2021 to expand into water treatment, another Bentley dominated market. For over five years, Esri and Autodesk have been developing hooks between their products, enabling the movement of BIM and GIS within their ecosystems.

Enter Cesium

So where does Cesium fit into all this? For many reasons, the company hasn’t previously seemed like an acquisition option. In much the same vein as Robert McNeel and Rhino, Cesium built a business based on community and established a huge network of around one million users, as well as about 10,000 developers, with powerful yet relatively low-cost GIS integration/distribution tools.

Cesium has a deep belief in the open source approach to software, putting a lot of effort into the development of Cesium. JS and its streamable, interactive 3D Tile open format, which supports vector, 4D, 2D, 3D, point clouds and photogrammetry. This is free for both commercial and non-commercial use and has been used to map subsurface, surface, airborne and space environments.

Cesium’s formats have been embraced by the likes of Google and NASA. Its data structures, meanwhile, also support other open formats, such as glTF for model info (asset information), as well as the latest advances in GPU acceleration. While the technology is a perfect fit for Bentley’s digital twin strategy, the culture fit was, on the face of it, incongruous to corporate customers.

Around the time of the 2020 Open Letter to Autodesk, I had a conversation with Keith Bentley, then Bentley Systems CTO, in which we discussed whether open source applications such as Blender BIM were the way to go. From that chat, I was left in little doubt that this was not Keith Bentley’s mindset, since he was strongly of the belief that programmers’ efforts should be rewarded.

However, he was more inclined to agree that open source data was perhaps a way forward, because for customers, the keys to data must remain in their hands. The whole premise of digital twins requires the assembling of data from all sorts of applications, in many file formats. In that respect, data trapped in proprietary silos is likely to be an industry-wide problem. In 2021, Bentley opened the iTwin.js library with source code hosted on GitHub and distributed under the MIT licence. Since then, Bentley has been seeking wider adoption of its iTwin data wrapper.

So, while I was pondering Cesium’s culture fit, I hadn’t considered Bentley’s cultural change. Its newfound belief in open data isn’t just a passing fad. It really is something that the company intends to deliver on.

When considered from that angle, acquiring Cesium takes Bentley closer to its goal of having open format technology that covers all the many different sources of data necessary to build an infrastructure digital twin. That could be scan / photogrammetry data, BIM data, GIS data, asset tagging and management data.

Of course, Cesium offers far more besides. Its super-fast 3D pipeline enables huge datasets to be visualised locally in Unreal Engine, on the web, on a mobile and in real time. The Cesium ecosystem also includes developers who may want to utilise Bentley’s wide array of SaaS analytical and simulation tools or BIM capabilities, and existing customers will be able to view their digital twins in geospatial context for analysis and service planning.

In conversation

In conversation with Cesium CEO Patrick Cozzi, he outlined for me his view of the deal. “Cesium is an open-source project doing massive scale 3D geospatial, open source, open standards, large models with semantics on the web. When Bentley found Cesium eight or nine years ago, they opened up our eyes. They said, ‘Hey, Patrick, this is more than geospatial. This can do the built environment. This can do infrastructure,” he said.

He continued: “When we brought 3D Tiles to OGC (The Open Geospatial Consortium) to make an OGC community standard, Bentley was part of that original submission team. This is going back to 2017. Bentley had ContextCapture, now called iTwin Capture, which was some of the first photogrammetry ever put into Cesium. We have had a long relationship with Bentley. We’ve known the Bentley brothers, the leadership team of today, and we think we share a lot of the same DNA. We like Bentley’s interest and commitment and authenticity around open source, open standards, and building a platform which uplifts the ecosystem. We know that that is Bentley’s belief and it’s where Bentley wants to take the future.”

We are transitioning from files to a data centric world, and customers need to have confidence and trust in how the data is going to be handled. We believe in a true open approach, which is based on open standards, open source and open APIs Julien Moutte, Bentley Systems CTO

A few days prior to announcing the acquisition, Cesium published a press release regarding its BIM integration technology preview. At that time, AEC Magazine reached out to the company, but they couldn’t answer, because they were busy finalising the deal. Cozzi added, “As you saw just before the agreement, we are doing more in AEC.’” I suspect that Bentley has a raft of technology to assist in that.

Bentley CTO Julien Moutte then gave me the Bentley perspective, “We are transitioning from files to a data centric world, and customers need to have confidence and trust in how the data is going to be handled. We believe in a true open approach, which is based on open standards, open source and open APIs,” he said.

“The iTwin technology stack is going to continue using more and more open standards. We are looking at creating and enriching the standard ecosystem with some new capabilities around BIM collaboration. We have discussed the limitations we’ve seen in IFC, for instance, and we’ve created BI-model technology, and I think one thing we captured in the room at NXT BLD is that not many know about (Bentley) iModels,” he continued.

“We need to learn how to be better in creating an ecosystem, a community. And I think that’s one of the things that Patrick and his team are going to bring to us. We want to create a thriving developer ecosystem on top of this platform, which is built around open data.”

Cesium has about 60 employees based in Philadelphia. They are mainly programmers, with about 10 people in sales – but sales are mainly inbound and focused on products such as its Cesium Ion SaaS 3D geospatial data hubs, together with large partnerships and hosting. The Cesium offices are located not too far from the Bentley Exton Headquarters. By joining forces with Bentley, Cozzi said that it will allow the company to achieve more industry impact.

Moutte also explained what he thinks Cesium brings to Bentley tech stack. “There are multiple facets here. Obviously, I believe that our users, the engineers of the world, would benefit greatly in having more context when they do their work, and we believe that the best way to provide this to them is by leveraging the Cesium technology.

“Today, we’re trying to do this with the iTwin platform, but I think there is a better way to do this when it comes to geospatial data, bringing in Google 3D Tiles, making sure that we can combine and bring all of that data in an environment in an aligned way, using the geospatial coordinates. Whether it’s underground, buildings or engineering models, it’s about more value to our users,” he said.

He concluded: “The huge Cesium ecosystem is consuming Cesium geospatial data. If they are bringing building models in, they don’t have the full detail of what those building models contain. It’s mostly geometry. There’s a lot of value we could deliver by providing access to the metadata of those building models. We have capabilities to bring in geospatial analysis, lots of simulation, whether it’s flooding, mobility, structures and visualising all of this in the context of geospatial is also very valuable. It’s a massive opportunity.”

Cozzi added, “BIM could learn a lot from these large GIS models. 3D Tiles doesn’t just stream the geometry and metadata for terrain and photogrammetry, but can also do that for the built environment. Up to this point, a lot of that has been done in OBJ files or FBX, which are standard graphics files. We thought we could help them more, so have built some new pipelines to preserve more of that semantic data, especially the hierarchical nature.”

So, for example, Cesium built a pipeline for IFC, and also into Revit, he explains. “Then we run our super-smart algorithms on the geometry and metadata, and frankly, the metadata might actually be heavier than the geometry. Then, in a domain-specific way, we slice and dice that into 3D Tiles, so that it’s streamed very effectively over the web, placed within a geospatial context,” he said.

“So where do we go next? Bentley brings a ton of domain knowledge about infrastructure and AEC, and we keep saying ‘better together’.”

Conclusion

Cozzi will now head up the iTwin platform developed within Bentley. While the technology benefit has been clearly explained, it also seems that Bentley hopes to preserve and learn from the open-source culture that Cesium has embodied, with its dedication to openness, performance and solving problems for thousands of users in many different industries.

While I still have my doubts about the potential size of market for digital twins within the building sector – insofar as there are so many buildings but the cost of making a twin is high – when you scale up the geo level and start talking about managing assets like roads, rail, national grids and power stations, then digital twins and asset management start to make a lot more sense.

The acquisition of Cesium is a major coup for Bentley, which will not only help it in its historic markets, but also introduce it (literally) to a whole new digital world

Bentley Systems wasn’t wasting time at its recent YII conference, hammering home its ‘open’ approach to data. The message from Bentley’s execs was clear: the company is putting its weight behind openness— the sub text being that some of its competitors are not.

The emphasis was hard to miss. In the first two keynote presentations alone, led by new CEO Nicolas Cumins and CTO Julien Moutte, the word ‘open’ was used a staggering 60 times.

While AI also got a strong showing with 47 mentions, it was obvious that Bentley was speaking to customers, and not trying to impress investors. The message? Openness isn’t just a token word; it’s a cornerstone of Bentley’s strategy. “Your data is your data always,” said Cumins.

Moutte outlined the three pillars of Bentley’s open approach: open standards where everybody that was granted access to the data can read and understand it; open source, where every developer can leverage that data; and open APIs, where users are free to take their data out whenever they want, instead of just being able to query it.

Cumins also touched on the complexity of infrastructure projects, which involve multiple organisations, teams, and disciplines “This complexity makes it impossible for you to rely on any single system or single vendor. Instead, you need an ecosystem that enables flexibility, integration and interoperability across different tools and platforms,” he said.

He also addressed a common concern among customers: “Don’t get locked in,” he said. “Make sure you retain control of your data.”

As AEC firms navigate the transition from files to a data-lake world, this message should resonate more than ever. With proprietary files (DWG / DGN / RVT) at least drawings and models could be accessed via Open Design Alliance (ODA) libraries. With proprietary databases, access is granted only via APIs, which are under the control of the vendor.

“We are not creating another silo,” said Cumins.

Looking ahead, Bentley is focused not just on the present, but on the long-term future. Infrastructure is built to last. “Our users must assure that this data, their data, remains accessible for decades to come, and we believe this is only possible with a truly open approach,” said Moutte.

At the heart of Bentley’s open strategy is the iTwin platform, a suite of APIs and services designed to help AECO firms develop digital twin applications for designing, building, and operating infrastructure assets. iTwin integrates data from various sources—specs, drawings, CAD and BIM models, reality captures, sensor data, inspection records, and more.


The platform is built on a schema specifically designed for infrastructure. While the majority of this schema is open-source, one component — the Parasolid geometry modelling kernel —is proprietary, as it is owned by Siemens.

As Cumins explained, “The schema goes beyond basic data exchange, ensuring that data isn’t just accessible, but its meaning can also be understood, whether you’re dealing with materials or structures or subsurface data.”

He emphasised that this schema helps engineers, constructors, and organisations maximise the value of their data. “We’re not keeping it to ourselves. We actively encourage others in the industry to adopt the schema. This is about moving the entire infrastructure sector forward together.”

Artificial Intelligence (AI)

Cumins described AI as a “paradigm shift” for the infrastructure sector, highlighting the massive scale of data generated during the design, construction, and operational phases. “It makes infrastructure a prime area where AI can have the greatest impact,” he said.

Bentley’s investment in AI dates back several years. In 2018, the company acquired machine learning and IoT developer AIworx, which former CTO Keith Bentley described as an “acqui-hire,” meaning it was made primarily for the talent. Since then, that talent has driven several successful AI use cases, primarily in asset operations. These include automatic object classification in reality meshes and using computer vision, IoT sensors, and machine learning for predictive maintenance—detecting issues before they lead to failures.

Many of these technologies now fall under Bentley Asset Analytics, a new product line that uses AI to provide insights into the condition of infrastructure assets. “This approach is especially important for critical infrastructure like bridges and dams, where monitoring and maintenance are key to ensuring long-term safety and performance,” said Mike Campbell, Chief Product Officer, Bentley Systems.

The portfolio includes Blyncsy, which utilises crowd-sourced dashcam footage and machine learning models to automate roadway maintenance and asset inventory. “AI can help identify roadside assets and assess their conditions, everything from a broken stop sign to a faulty streetlight to a fresh pothole,” explained Mike Schellhase, VP of asset analytics at Bentley. “These insights feed directly into the infrastructure digital twin, the iTwin, and are presented in iTwin Experience to show the latest conditions and context.”

Another product, OpenTower iQ, uses drone imagery, data, and AI to manage telecom towers throughout their lifecycle, handling everything from data acquisition and visualisation to structural analysis, site design, and maintenance.

Bentley plans to expand these solutions to cover a broader range of asset types, offering owner-operators increasingly advanced AI-powered tools.

Now, the company is pushing AI further into the design phase, using generative AI to automate repetitive tasks.

The first of a new generation of AI-powered design tools is OpenSite+, which is used for civil site design (including roadways, parking lots, and buildings).

The software features a co-pilot experience that taps into knowledge stored in documentation, specifications, and 3D site models through natural language interactions. “We can ask questions like, ‘Can I build a hotel in this area?’ or ‘Do I have enough parking to meet my requirements?’” said Francois Valois, VP of civil infrastructure at Bentley.

“At this stage [in the design process], we don’t know if our layout is optimal, so we build a neural network that evaluates thousands of alternatives to find the best one, optimising costs while meeting engineering requirements,” Valois explained. The software also offers AI-powered earthwork optimisation, which Bentley has enhanced by wrapping its current engine in a neural network to make the process significantly faster.

Another key feature is automated drawing production, a hot topic in AEC as it can save so much time and money (read this AEC Magazine article). According to Bentley, drawing production can account for up to 50% of a site design project’s time, and Bentley’s AI-powered tools automate annotation, labelling, and sheeting, optimising the placement of labels and dimensions, and according to organisational standards.

Currently, drawing production isn’t built directly into OpenSite+, but rather, it’s routed through OpenSite Designer, an existing power-platform based product based on MicroStation. However, as Campbell explained by going down this route, the technology can then be made available in other power platform-based applications. Watch this space.

This process will take time, as the large language model (which Campbell playfully wants to call a “large drawing model”) has so far only been trained on tens of thousands of site plans and only from North America. “We’ve got to do that for the UK, for Australia, for all of the other places, because the standards are all different,” Campbell said. “Roadway plans have a different look and feel, right? So, we’ve got to build a model for that.”

As to where the training data has come from, Campbell explained that most of it is sourced from a licensed open-source library, though some customers have granted Bentley explicit permission to use their data. “We’re not just going and taking plans from random [customer] accounts,” he said, adding that Bentley keeps track of the provenance of every data set used. If a company decides to withdraw its data, Bentley will retrain the model accordingly.

In the future, customers will be able to train the AI model on their own data. “Say you’ve got 6,000 site plans—you can put them into your own local, retrained version of the model, and that will be yours and yours alone.”

As for the future of AI at Bentley, Campbell hinted at broader applications. “Instead of using AI to generate a site, could we use AI to generate other designs, a bridge design, for example, optimise a road for – not just the obvious ones like curvature and safety, but things like carbon impact and cost and time.”

“Civil engineers can imagine a certain section of the design space. AI can imagine a much broader design space,” Campbell added. “The good news is that in engineering, we’re governed by rules of physics and standards and safety factors and all those kinds of things, so that limits it, but still, it’s bigger than what a typical engineer can think about.”

Desktop deployment

Beyond AI, one of the most significant aspects of OpenSite+ is that it’s a completely new type of application. It’s iTwin-native, so it writes directly to an iModel without needing to go through intermediary formats like DGN. Unlike many modern applications, it’s also a desktop application, rather than running in a browser.

“We’re not yet convinced that all of these engineering workloads are going to be able to work on the cloud,” explained Campbell. “We also want to be able to take advantage of local compute. And we’ve also got our eye on these new AI processors that are coming out – NPUs – and we want to be able to take advantage of that.”

OpenSite+ works both online and offline, syncing changes (deltas) when connectivity is restored. Bentley is taking the same desktop/iTwin-native approach with its new visualisation tool, Advanced Visualization, which is built on Unreal Engine (more on this later).

Campbell acknowledges that more tools are in the pipeline, either going through validation or still in the research phase, and they will all follow this same framework.

With many new AEC software tools from startups running in the browser, we asked Campbell if this would influence Bentley’s acquisition strategy. “Not necessarily, but it would be a consideration,” he said. “We certainly look at architecture [of the software].”

He also admitted that technical integration has become a key focus for Bentley, which is one reason why acquisitions have slowed over the last couple of years. The priority now is ensuring that products work seamlessly together. “The idea of convergence and integration, ensuring that data flows smoothly across applications and the lifecycle, and informs the infrastructure digital twin—that’s the goal,” Campbell emphasised.

Back into BIM?

Bentley once held a strong position in architecture, especially in the early 2000s with MicroStation and GenerativeComponents, a pioneering computational design tool that preceded Grasshopper.

However, in recent years, the company has shifted its focus away from this market. Given the growing interest in next-generation BIM tools, the question arises: does Bentley have aspirations to get back into BIM?

“Our focus right now is absolutely on horizontal infrastructure, and there’s plenty there to keep us busy,” said Campbell.

“But I’m reluctant to say never, especially in light of the sentiment of the broader AEC ecosystem. In particular, I’m thinking about open letters, I’m thinking about the AEC spec [AEC Future Software Specification]. I’m thinking about what their vision is for the tools they’ll use in the future. And I’m thinking about the tools that we’re building. And when I read that spec and I look at our strategy, it’s not dissimilar. It’s not a slam dunk, but we’re in the ballpark.

“The data lake, the elements of openness, design in context and at scale. That’s in the AEC spec.”

Geospatial – giving assets context

Last month, out of the blue, Bentley Systems acquired Cesium, developer of an industry cherished 3D geospatial platform – Cesium ion – with an ecosystem of open standards, including Cesium.JS and 3D Tile technology. (To learn more about the acquisition read this AEC Magazine article).

“With the acquisition of Cesium, we are now able to provide a 3D geospatial view of infrastructure,” said Cumins. “We are effectively changing the vantage point of an infrastructure digital twin, from the engineering model of the infrastructure asset to the planet Earth, upon which we geolocate the engineering model and all the necessary data from the surrounding built and natural environments.”

However, as Cumins explained, perhaps the most significant aspect of the acquisition is that Cesium as a company, perfectly aligns with Bentley’s vision of open standards and interoperability.

“The combination of Cesium plus iTwin enables developers to seamlessly align 3D geospatial data with engineering, subsurface, IoT, reality, and enterprise data to create digital twins with astonishing user experiences that scale from vast infrastructure networks to the millimetre-accurate details of individual assets—viewed from land, sky, and sea, from outer space to deep below the Earth’s surface to support engineering workflows.”

Cesium’s 3D Tile technology makes light work of huge geospatial datasets by streaming only what the user needs for any given view.

It uses a concept called hierarchical level of detail (HLOD), where you basically have a tree of tiles – the root being the least detailed version, the branches adding more detail, and the leaves having the highest resolution.

3D Tiles can handle a whole smorgasbord of 3D geospatial data including point clouds, reality models (derived from photogrammetry), and 3D buildings. Through its recent AECO Tech Preview Program it can also handle BIM models (IFC and Autodesk Revit), complete with metadata which can be used for querying, filtering, styling, and analytics.

The long-term plan is to unite the iTwin and Cesium Ion platforms, but as Patrick Cozzi, CEO of Cesium and now chief platform officer at Bentley, explained nothing will be done without input from the community. The potential is limitless, he said. “We can add voxels for biometric visualisation, for subsurface, we can add Gaussian splats for higher visual quality for point clouds; we can do temporal tiles to help show the change in construction sites over time.”

Building on this geospatial focus, Bentley announced a new strategic partnership with Google which will integrate Google’s comprehensive repository of 3D geospatial data with Cesium and Bentley’s iTwin platform.

“Consider a large urban development project where multiple infrastructure systems are used – roads, bridges, energy and water networks – that must be coordinated across various stakeholders,” said Cumins. “By integrating Google’s vast 3D geospatial data with Bentley Cesium technology and iTwin platform stakeholders can visualise their assets, both existing and plan in full real-world context.”

Advanced Visualization

Cesium 3D Tiles and Google 3D Tiles play a key role in Advanced Visualization, a new product from Bentley powered by Unreal Engine, designed to overcome the challenges of creating immersive, interactive, and photorealistic infrastructure experiences.

This software integrates seamlessly with iTwin for live access to up-to-date project data, enabling users to navigate massive models in real time using Cesium 3D Tiles.

As Greg Demchak, VP, emerging technologies group at Bentley explained, users can enrich their scenes with additional context and content: “Context in the form of Google 3D tiles, and content in the form of easy to place trees, cars, scale, figures and equipment.”

Advanced Visualization functions either as an out-of-the-box solution or as a flexible platform for building custom applications and is currently in Early Access.

Up front carbon analysis

One of the key challenges in achieving sustainability on infrastructure projects is the time-consuming nature of carbon reporting, which is typically handled by specialists.

Kelvin Saldanha, associate director at WSP, elaborated: “Once you’re ready to measure carbon, it needs to go through a rigorous quantity take-off process, including design compilation and data cleansing, before that data can be used in third-party software.”

This process can cause significant delays. As Saldanha noted, “A lot of times that delay means that the design team doesn’t know what the carbon score is until the design is very mature, and you kind of miss the opportunity to reduce your carbon score.”

He emphasised that the best opportunity to make a meaningful impact on carbon reduction is in the early stages of a project’s design cycle.

WSP has been testing new carbon analysis capabilities in iTwin Experience through Bentley’s Early Access Program, which Saldanha said gives the design team much-needed transparency in the earlier phases of a project. “Continuous calculations during the design process allow for accurate carbon reports to be generated much earlier in the project lifecycle,” he added.

What truly sets Carbon Analysis apart, according to Saldanha, is the software’s visualisation capabilities. “Instead of sifting through spreadsheets and tables, designers can now exchange data directly with EC3, view heat maps, and interact with them to quickly identify where they’ve got carbon intensive features on their project, and then they can target those.”

Bentley’s new Carbon Analysis capabilities are available to iTwin Experience users at no additional cost, though a separate licence is required for carbon assessment calculators like EC3 or OneClickLCA.

Conclusion

While many AEC software companies talk openness, few demonstrate the same level of commitment as Bentley – though open standards, open source and open APIs.

At YII, Bentley’s executives made this abundantly clear with deliberate, impactful messaging: “Don’t get locked in,” “Your data is your data,” and “We’re not creating another silo.”,

This was a strong signal to customers that the keys to their data must remain in their hands, a crucial point as the AEC industry transitions from file-based systems to data lake environments.

Of course, Bentley’s approach isn’t purely altruistic; as a company with shareholders now, it stands to benefit from the industry moving towards storing data in its model wrapper.

And while third parties can choose to use the open specification to create an iModel / iTwin independently, Bentley has a suite of mature data management, authoring and analysis tools and services ready to go.

But with this open approach it’s clear that Bentley is playing the long game—a smart strategy considering the long lifecycle of infrastructure assets.

Cumins pointed out that the software and platform used to manage these assets will evolve considerably over time. “So, by ensuring that our systems remain open, we allow organisations to adopt new technologies and innovations while still being able to access and build on their historical data,” he said.

Of course, it’s possible that future platforms may not even be developed by Bentley, but the key takeaway for customers investing in the Bentley iTwin ecosystem is this: they will always have the freedom to choose.

Twinview (digital twins) https://aecmag.com/digital-twin/twinview-digital-twins/ https://aecmag.com/digital-twin/twinview-digital-twins/#disqus_thread Fri, 24 May 2024 07:10:06 +0000 https://aecmag.com/?p=20694 We explore Space Group’s Twinview, one of the most advanced BIM digital twin offerings available today

The post Twinview (digital twins) appeared first on AEC Magazine.

Space Group is not only an architecture firm, but also a hotbed of AEC-related software development. The company’s technology portfolio includes Twinview, one of the most advanced BIM digital twin offerings available, as Martyn Day reports

It’s been a few years since we last looked at Twinview, the digital twin software from Space Group, based in Newcastle upon Tyne, UK. Over the intervening period, the term ‘digital twin’ has become increasingly prevalent in the industry, with big software firms like Autodesk dedicating considerable resources to creating new applications for what is expected to be a big market.

Space Group, headed by Rob Charlton and group CTO Adam Ward, is actually a collection of companies. Its activities include a functioning architectural practice, but it is also a hotbed of software development. The technology developed at Space Group was initially created to service the firm’s own needs, but it has since expanded its activities to provide bespoke BIM solutions for key industry players, as well as commercial software for the general market.

Space Group caught the BIM bug early on in Revit’s development. The company then ran with the idea, creating along the way the Bimstore for software components, BIM.Technologies for consultancy services, and an annual conference (BIM Show Live). Thanks to its efforts, the UK’s North East has become a centre for advanced BIM skills.

The twin conundrum

Before launching into the subject of Space Group’s Twinview software, I must first address the elephant in the room. That elephant, of course, is the term ‘digital twin’, which has become somewhat divisive.

The whole concept of digital twins has been overhyped, leading to the emergence of two distinct camps. The first camp is populated by those who live, sleep, eat and breathe digital twins, seeing the technology as a natural expansion of BIM. For that reason, they are convinced it will be huge.

The second camp is populated by those who roll their eyes at the term, seeing it as yet another case of ‘the Emperor’s New Clothes’, in an industry particularly prone to that affliction.

In my view, the digital twin is a great concept in theory — but there are commercial practicalities to consider. In short, the utopians have to come to terms with the reality of its niche appeal, which means limited market demand.

All that said, Twinview is one of the digital twin products that has been in the market the longest. That’s given Charlton the experience to admit that the concept has not necessarily found a home in the plethora of use cases predicted.

For instance, digital twins are not an easy replacement for, or update to, traditional computer aided facilities management (CAFM) software and associated workflows. Instead, the concept has seen more traction in London, where firms with extensive buildings portfolios need to ensure efficient running of these properties, in order for them to qualify as green investments when used as assets in investment property funds.

So while there are certainly digital twin customers out there, they have to be hunted down. In most cases, there is a very specific problem that needs solving. Securing sales is not, as many in the industry would like to believe, like shooting fish in a barrel.

As Charlton puts it, “People don’t buy things because they are clever bits of technology. You’ve got to have a value proposition.” A lot of BIM people may suddenly be styling themselves as digital twin experts, he continues, but the truth is that there are not many real digital twins in the world.

That said, Twinview has customers located in many different nations, he continues. “We’ve got live projects all over the world: South Africa, Abu Dhabi. And basically, they’re using Twinview for lots of things. It’s a place to bring everything together. It could be your single digital model. It could be to improve your tenant experience. And it’s fantastic for golden thread. It does all of that. One of the big things is understanding the building — IoT sensors telling you how much energy you are using, where it is being used, how it is being used. Clients are using it that way to optimise their buildings.”

With four years experience and feedback from users giving Space Group a better understanding of the multiple value cases that firms use to cost-justify ‘twin’ technology, Twinview has expanded, become more flexible and now has a highly modular approach

It’s a five-year project, he says, and Space Group is still very much an early adopter. “We’re still testing the use cases. We’re still trying to find examples. We’ve got over 300 buildings, over 2.5 million tracked assets, from a school in the UK, to an 85-floor tower in the Middle East, to the National Archive in New Zealand.”

The company is also doing some work with the NHS around compliance, as well as other firms concerned about asset management. Other customers need metrics for their annual environmental, social and governance (ESG) reports. The best adopters, he says, own their own estates and operate their own buildings.


Twinview


Spotlight on Twinview

Through the various phases of design, build and operate, Twinview is an application that aims to create a ‘digital thread’ to manage data throughout the lifecycle of a building. It collates data from multiple inputs, supports content collaboration and assists in creating documentation during construction for operations. It also connects to IoT sensors, runs predictive maintenance analysis, replaces CAFM and delivers personal tenant experiences via custom mobile apps.

With four years experience and feedback from users giving Space Group a better understanding of the multiple value cases that firms use to cost-justify ‘twin’ technology, Twinview has expanded, become more flexible and now has a highly modular approach.


Twinview


It’s no longer an all-or-nothing solution, nor solely reliant on a BIM model as its starting point. It’s just as happy providing a 2D experience, or operating without any graphical elements and acting as a conduit to IoT sensor data. This enables the product to better align with customer needs and budgets and to also address buildings that do not have a BIM twin and may only ‘exist’ in design terms as scanned documents.

The IoT connection in Twinview has had a refresh. As Ward explains, a more interchangeable way to integrate real-time data into Twinview was needed. In response, the company has introduced Node Assistant, which is based on the IBM Node-RED flow-based, low-code development tool for visual programming. In this way, says Ward, “we decouple the data ingestion layer from the application.”

This enables Twinview to integrate with BACnet and Modbus building management communications protocols, as well as other third-party systems. Using this highly configurable plug-and-play interface, users can set up all manner of real-time data streaming connections and rules.

One of the known limitations of many web-based twin applications is that linking groups of IoT sensors through web based protocols can generate so much web traffic that legitimate traffic flows may be misdiagnosed by service providers as denial of service attacks. To get round this problem, some commercial digital twin applications limit the frequency with which sensor data can be reported, resulting in measurements taken at intervals of minutes, rather than seconds. Twinview, by contrast, can pull data at very high frequency rates and run real-time monitoring. Using the Node Assistant, data can be transformed, viewed and used to set off other actions via logic, generating notifications or automated building functions, based on real data.


Twinview


Twinview now has a bunch of tools intended for use in the construction phase. Ward highlights that traditional digital twin workflows have been viewed as something to put in place at the end of construction, prior to hand off. Twinview’s O&M (Operation and Maintenance) Builder enables the user to define the O&M template to create manuals. They define their requirements in Twinview and then basically allow the design team to upload during construction.

In this module, ‘funnels’ can be set up for project participants to populate relevant folders with files for assets found in the building. This is a smart way to collate all the relevant documents required for record-keeping and downstream use. By assigning the upload of documents to individuals, the system automatically sends out alerts and monitors progress on the number of documents expected to be handed over at delivery.

There are whole document submittal workflows built into the system and everything is centrally and securely stored. O&M Builder can auto-generate O&M manuals from these files. If files change, O&M Builder saves copies with each amendment, keeping a history of revision. This process can be carried out in parallel with construction and saves the ingestion of huge amounts of documents all in one go at the end of a project.

Working in 2D mode

One of the more surprising additions to Twinview is support for 2D, which uses CAD drawings and even supports scans. All asset information can be associated with 2D elements, with associated dashboard reports, and all the 3D features are available in 2D use.

This aligns Twinview with more traditional CAFM workflows, where assets can be searched for and automatically displayed. Ward suggests that, in onboarding with a 2D approach, building a digital twin is harder, because CAD data is “more dumb” when compared to BIM data with all its rich metadata. However, many buildings simply don’t have a BIM model.


Twinview


“In Twinview, we can bulk upload 2D,” Ward explains. “Every project has an asset register, dictating which assets belong in which rooms. Data inherently has a hierarchy and structure. Assets are usually blocks, which we can identify. Every room typically has a polyline around, which defines the extents of the room and the architect would use this to work out the floor area. We just hook into what already exists.”

“The beauty of Twinview,” Charlton adds, “is that, if you mature down the line, you can still use Twinview and add BIM, IoT, create dashboards and build O&M manuals.”

Value points

The journey of Twinview, and the capabilities that have been developed, tell the story of what happens to digital twin technology when it meets reality.

Customers have many value points which start them on a twinning journey. There is no one holistic ‘digital twin’ religion driving customers. It’s all about need.

The 3D nature of BIM-driven CAFM does not really add that much value. It’s still all about assets, dataspaces and performance.

The idea that a digital twin can start with a scanned drawing, a DWG or a DGN is just as relevant — and probably more common — than the software industry would like to admit. This experience, along with customer feedback, has shaped the Twinview experience as it stands today. And that’s why this product is so incredibly adaptable.

Bentley Systems to use technology for monitoring infrastructure assets and Worldsensing for monitoring geohazards

Topcon Positioning Systems has announced strategic agreements with Bentley Systems and Worldsensing to integrate its GNSS (Global Navigation Satellite System) technology into the companies’ software and connectivity solutions.

As part of its agreement with Bentley Systems, the infrastructure engineering software company, Topcon has provided access to its web-based GNSS processing engine.

Bentley has integrated the technology into its iTwin IoT monitoring solution, which can be used to monitor a wide range of infrastructure assets.

“We’re excited to announce this integration of Topcon’s GNSS technology into our suite of IoT-based monitoring solutions,” said Steve Bentley, senior director of Infrastructure IoT for Bentley Systems.

“This integration will enable our users to combine cost-effective geospatial monitoring data with the wide range of geotechnical, environmental, and structural sensor data that we already support — providing real-time asset intelligence that can be combined with engineering data to advance infrastructure digital twins.”

Worldsensing, an IoT specialist offering connectivity solutions for geotechnical, structural and environmental monitoring, has integrated the Topcon AGM-1 GNSS receiver with its Thread X3 broadband product.

According to Topcon, the result is a new Accurate Positioning System for monitoring geohazards such as rock falls and landslides in pit mines, rail embankments and other ground structures.

“This will empower industry professionals to proactively identify potential risks of subsidence, heave, landslip, settlement and undertake preventive measures,” said Ian Stilgoe, vice president of Emerging Business for Topcon.

“Mining operations and the rail industry will greatly benefit from this collaboration. Professionals in these fields can now access a comprehensive monitoring solution that ensures the safety of their operations while optimising productivity, all at a much lower cost than before.”

Through new partnership, companies plan to drive adoption of digital twins

Hexagon’s Geosystems division and the Nemetschek Group, which owns leading AEC brands including Graphisoft, Allplan and Vectorworks, have formed a strategic partnership with a view to ‘accelerating digital transformation within the AEC/O industry’.

As a first step, the partnership will look to drive the adoption of digital twins.

The two companies aim to provide customers with tools, services and expertise for an ‘end-to-end digital twin workflow’ by joining the up-to-date building data through Hexagon’s reality capture solutions with building operations powered by Nemetschek’s dTwin.

Hexagon offers ‘end-to-end’ reality capture and Scan2BIM solutions to automatically capture accurate and real-time field data. Its AI-powered solutions also support building analytics and simulations, generate progress insights as well as provide an immersive experience for navigating assets during design, construction and operations through its VR/AR and positioning technology.

dTwin, Nemetschek’s new cloud-based digital twin platform, delivers data-driven insights and helps customers to manage facilities from design to operations. According to Nemetschek, it is the first solution in the industry that fuses all data sources of a building in one overarching view.

dTwin brings together relevant information from CAD/BIM, Integrated Workplace Management Systems (IWMS), and more with real-time streams from building operations – thus, according to Nemetschek, providing value via visualisation, data analysis and assets management. With the platform, owners and operators can optimise building operations based on real time information and data-funded decision criteria.

“The future is here — digital twins make work easier, insights available and decisions better,” says Thomas Harring, president at Hexagon’s Geosystems division.

“With that, they are paving the way for a more sustainable future. Through our combined strength, we make this a reality for our customers and supercharge the buildings and infrastructure industry with data continuity and digital twins at scale.”

“We are very excited to partner with Hexagon”, says César Flores Rodríguez, chief division officer planning & design, and digital twin at the Nemetschek Group.

“Together we will build digital twins for the large market of existing buildings, making those future proof. Also, we aim to address efficient and sustainable building operations and smart renovation, retrofit or revitalisation projects.”

Omniverse Cloud APIs let developers stream interactive ‘digital twins’ into the mixed reality headset

Nvidia has introduced a new service that allows firms to stream interactive Universal Scene Description (OpenUSD) industrial scenes from 3D applications into the Apple Vision Pro mixed reality headset.

The technology makes use of Nvidia’s new Omniverse Clouds APIs (read our story), using a new framework that channels the data through the Nvidia Graphics Delivery Network (GDN), a global network of graphics-optimised data centres.

“Traditional spatial workflows require developers to decimate their datasets – in essence, to gamify them. This doesn’t work for industrial workflows where engineering and simulation datasets for products factories and cities are massive,” said Rev Lebaredian, VP of Omniverse and simulation technology at Nvidia.

“New Omniverse cloud APIs let developers beam their applications and datasets with full RTX real-time physically-based rendering directly into vision pro with just an internet connection.”

In a demo unveiled today at Nvidia GTC, Nvidia presented an interactive, physically accurate digital twin of a car streamed in full fidelity to Apple Vision Pro’s high-resolution displays.

The demo featured a designer wearing the Vision Pro, using a car configurator application developed by CGI studio Katana on the Omniverse platform. The designer toggles through paint and trim options and even enters the vehicle —  blending 3D photorealistic environments with the physical world.

“The breakthrough ultra-high-resolution displays of Apple Vision Pro, combined with photorealistic rendering of OpenUSD content streamed from Nvidia accelerated computing, unlocks an incredible opportunity for the advancement of immersive experiences,” said Mike Rockwell, VP of the Vision Products Group at Apple. “Spatial computing will redefine how designers and developers build captivating digital content, driving a new era of creativity and engagement.”
