Years back, the construction industry began focus on industry foundation classes (IFC) a data model for describing architecture, engineering, construction and operations (AECO) data. The specification has helped ensure it is simpler to export data between tools. A substantial bottleneck, though, is that IFC tells construction software vendors only what type of data to add, not how exactly to represent it in a specific file format, that may result in ambiguity and significant manual effort to talk about data across tools.

Now, though, Nvidia is implementing IFC along with the universal scene description (USD) extendable underpinning the Nvidia Omniverse. This complements Nvidias broader efforts to develop connectors for various 3D authoring tools for the AEC industry, including Autodesk Alias, Autodesk Civil, Siemens JT, SimScale and Open Geospatial Consortium formats.

The USD implementation for IFC continues to be in first stages, but after the effort gets rolling, it promises to streamline construction workflows involving multiple tools from different vendors. It’ll ensure it is easier for engineers to benefit from Nvidias rich AI tooling to investigate 3D data, simulate the impact of different design decisions and automatically generate a 3D inventory to boost maintenance and operations.

Ensuring cross-platform consistency is a trial for various software companies, George Matos, senior product manager of Omniverse AECO at Nvidia, told VentureBeat.The prior development of standardized and open file formats allowed bridges between various AECO authoring applications. As technology and its own functions in AECO progress, we have been considering more extendible formats to permit full cross-platform collaboration, along with expanded functionality on the open extendable. This implies enabling an open dialogue, as they say, between your design applications and USD. While technology is in constant development, we have been targeting full fidelity and consistency between your authoring applications and formats and Nvidia Omniverse, along with allowing proprietary functions and compute at the authoring source or within Omniverse.

Matos sees these efforts as planting the seeds for leveraging construction data across more processes. For instance, an automobile manufacturer might create a physically accurate digital twin of its factories and cars and use these same ground truth assets within their sales, marketing and customer configurators. This involves all AECO data from the companys factories, CAD data from its assembly lines, design data from its fabrication models and also the autonomous robots that operate these facilities to totally donate to one virtual model. These workflows need a standardized data format and framework to help keep all 3D assets and data synchronized at high res and fidelity.

IFC helps transfer

In the late 1990s, there is no easy solution to move data across various engineering and design tools. So, AECO firms and software vendors came together to simplify the procedure. However, instead of focus on a particular extendable like GIF for pictures and MP3 for audio, they developed a data standard, leaving it around each vendor to implement it right into a extendable. IFC helps it be suitable for focusing on how varying elements in a building connect, such as for example what sort of handle, door, wall and room fit together in a structure.

This managed to get simpler to share data, but with limits.

Generally, IFC can be used as sort of one-way transfer mechanism, said Greg Schleusner, director of design technology at HOK and co-director of the technical room at BuildingSmart, which stewards the IFC standard.

This one-way flow helps teams export data for analysis, detecting scheduling problems, or simulation. But organizations generally returned to the initial tool when changes were required.

One underlying challenge is that the many CAD tools may use various ways of representing 3D data. For instance, some work with a mesh approach, while some think of the planet as solids.

Most of these tools have separate views on the planet and how exactly to represent geometry, which is where interoperability is most challenging, Schleusner said.

Consequently, the tools find yourself linking to the info as a reference instead of performing a design transfer, which may allow teams to take the info right into a new tool and progress it.

Its certainly possible and technically capable, it really is not used often, he explained.

USD to modularize data

Nvidias implementation promises to make it easier to represent IFC along with other data concerning the built world in a far more consistent format. Furthermore, it creates it simpler to extract information for specific use cases. Schleusner believes this can make sharing a subset of information with a contractor easier. This may also ensure it is better to implement suggestion systems that recommend specific forms of door assemblies for a specific project, just as GitHubs Copilot tool makes coding recommendations.

Nvidia is betting on USD to end up being the dominant format for allowing collaboration, computation, AI workflows and design across industries. Omniverse is made entirely on USD. Matos said they’re dealing with AECO leaders, including Autodesk, Bentley Systems and Graphisoft, to create connectors to the Omniverse platform.

Nvidia is actively developing capabilities internally sufficient reason for its ecosystem partners for connecting more integral systems and data types, including IoT, BOM data, piping and instrumentation diagrams (P&ID) and much more, to Omniverse.

Simulating real-world and virtual data together allows optimal operations of facilities, said Matos. That is one of many drivers behind the open data format approach of using USD with Omniverse.

Later on, Matos expects this may permit the AECO industry to go from building several static independent models to building live comprehensive digital twins. This can give a live, single-source virtual representation of buildings, environments and cities. This may help train AI agents on a large number of scenarios before live implementations in real life.

I’m happy to start to see the likes of Nvidia, Unity, Unreal finally step in to the arena of the built environment. Better late than never, said Steve Holzer, principal at HolzerTime, an architectural and planning consultancy and person in the infrastructure working group at the Digital Twin Consortium. As these tools novelty wears off, it’ll expose the incredible value of engagement within their physical space open to a broad audience.

He believes one of the primary opportunities would be to make it simpler to contextually parse data for specific use cases. He believes that IFC is an extremely heavy data structure. Just a few groups have discovered methods to leverage it across domains, such as for example COBie for operations, SPARKie for electrical, HVACie for HVAC and WSie for water. USD will make it simpler to develop new AI models for parsing structure in the manner that NLP tools parse medical entities from health records.

AI/ML will exponentially improve the value of data in every dimensions once the industry understands how exactly to utilize it beyond novelty, Holzer said.

Barry Bassnet, an electronic twin technical expert, has been using photogrammetry ways to capture 3D types of the built environment for 43 years. He could be worked up about the prospect of USD to transform the construction industry.

USD gives us a language to emulate to some extent precisely how our brain works and apply it to new processes, particularly AI, he said.

He believes the missing link is really a tool that automatically meta-tags the built environment. Today, folks have to manually craft links about and between spatial entities to various documentation, such as for example PDFs and their content. The mix of USD and auto-tagging capabilities would ensure it is better to specify a lock for a window and connect to a 3D repair manual or get yourself a replacement key.

Bassnet watched with excitement as VRML came and faded because of bandwidth overhead.

USD is the greatest chance of getting a method for the metaverse and the idea of digital twins to work, he said.

Schleusner believes the AEC industry could study from the success of USD in entertainment. Increasingly, the entertainment industry is creating improvements to USD instead of proprietary file formats. Because of this, entertainment workflows can exchange data directly between tools instead of through more technical transformations through APIs. Schleusner believes the AEC industry must adopt an identical method of achieve the type of innovation promised by digital twins for the built environment.

Probably the most instructive thing for the built world to eliminate from USD is that it’s easier to speak to one dataset versus needing to speak to many application APIs, said Schleusner. The brand new IFC implementation for USD will shift the needle toward more of an interchange instead of interoperability approach. This is the only way we shall get much nearer to success.
