building

Architects, engineers, and contractors are leading the adoption of ‘extended reality’ tools.

I’m hovering in the air, looking into an equipment-stuffed mechanical room on the roof of a high-rise. There’s a pipe running across the utility space and connecting down into the innards of the building’s plumbing system—and from this vantage point, it’s clear that something’s wrong. An elbow in the pipe is misaligned with those around it, and wherever the other end is going, it’s not going to match up with the intricate maze of pipes it takes for a tower to function. Floating in space and staring down this small but potentially disastrous flaw, I can just imagine the expense and effort it would take to fix it. Luckily, this building hasn’t been built, and what I’m looking at is just an elaborate digital mock-up.

This impossible view is made possible through virtual reality. I’m wearing a Meta Quest 3 VR headset, and touring a digital model of a demonstration building created by the architecture, engineering, and construction software giant Autodesk. The company is showing off Workshop XR, a new digital workspace for designers, engineers, and general contractors that creates an immersive way to inhabit the 3D digital models that are used to design and build pretty much any building of scale in the modern world. 

The purpose of Workshop XR is to improve what’s known as design review, or the preconstruction double-checking that goes into identifying problems and refining designs before the first shovel hits the ground. The software creates a one-to-one digital version of the building that stakeholders can walk through virtually using VR headsets to experience the space more viscerally than they can when looking at a screen. They can also see when a pipe isn’t in the right place.[Image: Autodesk]

Whether it’s through the fully immersive virtual reality of a headset like the Meta Quest, or in the digitally overlaid mixed reality of see-through hardware like Magic Leap and Apple’s Vision Pro, this technology is already changing the way buildings get designed and built.[Image: Autodesk]

SOFTWARE EVOLUTION

Buildings are now being designed in 3D from their earliest iterations. Industry-standard design tools such as Revit and Rhino make it intuitive for designers and builders to take an idea and turn it into a three-dimensional digital model that can be made construction-ready in remarkably little time. But while the model is 3D, how that model is viewed is typically not, and that can lead to problems during construction. 

“Reviewing on a 2D screen is inherently limiting when you’re building a building. It’s really easy to miss things,” says Gabe Paez, head of XR products at Autodesk. “When you’re in that building at the end of the project, you see things that you just didn’t see when you were designing.”

Paez says Autodesk’s WorkshopXR is a way to make sure those mistakes don’t find their way into the finished building. Instead of that misaligned pipe being discovered by a contractor or inspector during the construction process and going through the expense and effort of deconstructing and reconstructing, the mistake can be detected and fixed in an immersive 3D model before it’s an actual problem. 

“An issue missed early on can have a massive impact downstream. And that impact is not just cost and time and dissatisfaction, but honestly it really comes down to waste,” Paez says. Using VR, project managers can reduce the on-site change orders that stretch construction timelines and the last-minute redesigns that can burn through an architect’s overtime budget. That makes the construction process simply more efficient. “There’s tremendous value to be created,” Paez says.[Image: Autodesk]

Others see benefits much earlier in the process. Christian Giordano is president and co-owner of the New York-based design firm Mancini Duffy where he’s led the creation of a virtual reality software suite called the Toolbelt. Using headsets in a dedicated design lab, the Toolbelt brings clients inside working 3D models of their projects to experience them spatially and provide design guidance that can be reflected in the model almost instantly.

“Our biggest problem as architects and designers is just getting clients to make decisions,” Giordano says. “We can do what a normal architect does in three weeks in three hours in one session because we are getting real-time feedback from the client.”

The system was developed over three years to speed up the process of translating a client’s desires into 3D models. Putting them inside the project as early as possible, the Toolbelt facilitates design conversations in a way that sketches and renderings can’t, Giordano says. “Our goal was to make it a seamless process so that if the client says ‘I don’t like that over there,’ we just move it right then and there in our Revit model, and it moves directly in the VR headset,” he says.

The tool has been especially useful with Mancini Duffy’s hospitality clients. One is Tommy’s Tavern and Tap, a sports bar chain with locations across New Jersey and the Northeast. Giordano says the Toolbelt design process has helped check off a very important box for the owner. “We will literally walk him around in virtual reality and he will sit at every single seat at a restaurant—hundreds of seats—and make sure he can see a television,” Giordano says. “There’s no drawing, no rendering that we could ever do that would give the client that experience.”[Photo: John Herr/courtesy Mancini Duffy]

Giordano says the Toolbelt is now used on every one of Mancini Duffy’s projects. The first client to try it out was Yann De Rochefort, whose Spanish tapas restaurant Boqueria has about a dozen locations across the U.S. He sees the Toolbelt as a way to collaborate with the architects.

“It used to be that when a restaurant was done, there would be perspectives that would surprise me, where I would say, ‘Oh, I really didn’t consider that you would have this viewing angle into the kitchen from the dining room if you sat at one of these tables,’” he says. “And that is much, much rarer now.”

De Rochefort has also worked with a newer version of the Toolbelt that can be used on location. Wearing an augmented reality headset inside the raw space of a future restaurant, he could toggle on the working model, overlaying into his view of the space as he moved around. “It really speeds up the design cycle,” he says. “Once you have it, you’re loathe to work without it.”[Image: Devco]

IN REAL SPACE

Headset tools can also serve to broaden access to the design process, especially with unconventional projects.

Hush, a New York based experience design firm, is working on interactive and public art elements of a $1.5 billion life science and innovation hub under development in New Brunswick, New Jersey. Intended to weave together the multibuilding district, the art and interactive elements Hush has designed are massive in scale, winding like giant ribbons from the public realm into and through the buildings. There’s a 40-foot-tall looping sculpture and a 65-foot-long digital screen embedded into the floor of a lobby. The design, Hush creative partner David Schwarz concedes, is a bit unusual.[Image: Hush]

“You kind of run out of language to talk with clients about it, to tell them what your intention is because they’ve never seen anything like this,” he says. “How do you tell people what it’s going to feel like to walk under football field-sized pieces of public artwork?”[Image: Devco]

One way is to show them. Hush partnered with the augmented reality headset maker Magic Leap to help visualize what it was proposing for the project. Using the headsets and a huge rented warehouse, Hush brought the project’s clients to experience a one-to-one scale model of their looping sculpture and floor screen installation. They could walk through and around the proposed design elements, seeing their scale and size through the headsets while designers on-site were adjusting the 3D model in response to their feedback.ADVERTISEMENT

Virtual reality, he says, allows for both perspectives—the top down, and the street level—giving designers a better sense for how their intentions will actually be seen and felt. Through a partnership with the VR headset maker HTC Vive, Yuen’s post-professional graduate students are bringing these perspectives, and many others, to their design exercises.Enrique Mutis, a grad student in architecture and urban design at Harvard, uses an HTC Vive Focus 3 headset [Photo: courtesy HTC]

“It allows you to occupy the space while you’re making decisions, so it really allows you to get a sense of scale. And it allows you to check your work and make sure it works before you get too enamored with it,” he says.

One project Yuen’s class has been exploring uses VR to get a feel for the development of a new urban district in the city of Boston. Others are focused on suburban settings, where development and open space are more spread out and where the experience on the ground can feel either too open and deserted or too clustered and compact. Designing with the headsets on, students can better balance the way land is used, and even think about the design in a more expansive way. 

“It allows us to consider nonhuman organisms,” Yuen says. “What is it like to be a deer in the suburbs of Boston? VR allows us to change our perspective to things like that.”West[h]ood rendering by Harvard University Graduate School of Design students Enrique Mutis and Sangwon Kim [Photo: courtesy HTC]

Virtual reality tools are also being used to think about designing nature, in a sense. Aidan Ackerman is an assistant professor of landscape architecture at SUNY College of Environmental Science and Forestry in Syracuse, New York. He’s been using virtual reality to visualize forests and urban tree plantings over time.

Using data-based software, Ackerman’s VR tool can simulate the growth of tree species under specific environmental conditions. For example, it can give forest land owners a time-lapse view of how their lands might change over time if they were to implement certain sustainable forestry practices. Or, it can offer underserved urban residents a look at how their street or neighborhood could change if foliage were planted there.
