The Augmented and Virtual Reality Brought to Life Through InfraWorks

DANIEL ILIYN: In case you didn't know where you're at, you are in the Augmented and Virtual Reality Brought to Life Through InfraWorks class. My name is Dan Iliyn. I work for David Evans and Associates. We're a civil engineering firm. I do mostly roadway design, and I'm based out of Portland, Oregon.

So I'm going to dive right into this. This is the class summary. I'm not going to read it. If you picked this class, I'm assuming you read that summary at some point to interest you in this class.

Some of the key learning objectives, I'm going to go through. Really quickly, to preface to this, this was intended to be a dual presenter presentation. Unfortunately, my second presenter had some unforeseen circumstances come up and couldn't make it to AU. So I am going to be filling in, obviously, and doing the whole presentation. I have some of his slides that I'm going to breeze over a little bit, but I'll just touch a little bit more on the augmented reality and InfraWorks side.

He was going to be touching more on the existing conditions and how you can gather existing conditions and better improve your experience within InfraWorks. So I do have a couple of slides that will still touch on that. So today we will talk about some existing conditions.

We're going to focus mostly on gaining a basic understanding on what is augmented reality and as well as a little bit of virtual reality and how that is used in InfraWorks. Most of this presentation, I'm going won't actually be using a project that I worked on, that is currently in construction, that I utilized InfraWorks from concept through final design. And I pretty heavily utilized augmented reality on this project.

So I want to talk about how that benefitted the project, talk about how I implemented it, and some of the responses I got back from the client. And then, finally, throughout this, we'll kind of gain some insight on where the industry is at in using AR and VR, specifically in corridor-based transportation design. Because AR and VR has been very prevalent when it comes to site design, and buildings, and architecture, but it hasn't quite made its way fully into my world, which is transportation, roadway design, bridges, corridors. So that's what I'm going to touch on here.

Again, who am I. I kind of already touched on this. I went to Oregon State University. Go Beavs. I've been with the firm that I'm with now for seven years, and I have been using InfraWorks for about five of those years. I jumped on it back when it was-- I think it was called Infrastructure Builder or something, in the infancy phase of InfraWorks. So it's been something that I've-- I've been in it from the beginning and I have seen it grow, and so I'll be able to talk to where it's at now, and maybe even a little bit where it's going.

So, for those that don't know what InfraWorks is, it is an Autodesk software that-- it supports connected BIM or CIM for the civil side. So it lets the designer and the social engineers plan and design infrastructure projects in the context of the real world. It allows you to take your designs on a Civil 3D or-- no, I'm not going to say the other software. Mostly Civil 3D, and bring them in and allow you to visualize it.

But a key part of InfraWorks, and what actually drove me to-- because I'm a designer. I live in Civil 3D. I love visualization. I always worked with SketchUp, if anybody here uses SketchUp. I built my entire home in SketchUp so that I could tell my wife every month when she wanted to move the house around, OK, hold on. Before I move the furniture, let me show you what it's going to look like. So I've always lived in this visualized world. I love it.

This tool though and what brought me to it is the fact that it is a design tool that allows you to also be visualization. So I'm not going to touch a whole lot on the design aspect of InfraWorks. And, actually, most of what I'm showing you today with this project, I used it as a visualization tool, because it is a great aggregator of data and information that allows you to visualize what your design looks like from Civil 3D.

So, again, a little bit more about InfraWorks. InfraWorks is-- this is a term that my co-presenter that's not here likes to use. He calls it the geospatial nexus. It is the software that is at the center that pulls BIM, CIM, and GIS all together into one and allows you to marry those together in a way that, again, allows you to visualize what you're working on.

So this is some of the existing data and some of what we're doing as far as collecting existing data, bringing existing data into InfraWorks. You're able to show GIS shapefiles very easily in InfraWorks. We do a lot of LIDAR data, develop a lot of DEMs and surfaces from a number of different sources.

We are building quite a bit into UAS. And I'll touch on that a little bit and kind of show an example of some of the data that we've collected with Unarmed Aircraft Systems. I'm going to need some more water.

But, again, some of the other existing data that you've got that you can suck into InfraWorks and visualize. You got existing data from 3D models from pipe networks, from 3D structures from Revit. And that can all be brought in and aggregated within InfraWorks. It allows you to show subsurface LIDAR.

And this is the last point that I just mentioned. We're able to grab data that you've collected with unarmed aerial systems and bring it into InfraWorks and you to have true context, existing context, that looks real and that is accurate. So I'm going to show-- there we go. So these are a couple of pictures of some of the UAS systems that we're using it at DEA, and we're really starting to dive into that as a primary form of collecting existing data.

And, again, I'm not the expert on this. Unfortunately, my partner is the expert, so I'm going to zoom through this a little bit and get to what I know best, which is InfraWorks, and how we use InfraWorks, and how we can-- once we've got some of the existing data within InfraWorks, how do I utilize it as a designer? How do I utilize it to implement augmented reality?

So, again, these are some images of some of the data that he has collected with an unarmed aerial system. What you see here is a very high def 3D mesh that he collected from photogrammetry just from flying a site. And what you can see is he pasted it into an InfraWorks. And these two images that you see up here, what it's actually showing you-- Does that work? Sweet-- is the overview and what the image looks like from up above. And then, if you zoom in, you can actually see quite a bit of detail in both the aerial imagery that's bringing it in, as well as it has 3D context to it as well.

So this was just picked up very quickly with a drone, processed and imported into InfraWorks. So this is zoomed out a little bit. You can see the existing data that InfraWorks brought in. For those that haven't used InfraWorks, Model Builder allows you to go out and very quickly aggregate existing data. It does it for you.

It grabs terrain data. It grabs Bing imagery, and it grabs some GIS road centerlines. Brings it all in and builds you an existing model. So what we're showing here is taking some of the data that we've collected with drones, and pasting it in, and then starting to utilize that data to build the existing context.

So there are point cloud processing tools as well in InfraWorks. These are very quickly developing. They're starting to actually become useful to where you can use the tools to actually pull out 3D models from a point cloud, as well as linear features, such as striping, and actually create those features within InfraWorks directly from a point cloud.

So, again, I'm not going to touch on the details of this, but this is the types of processes that we're now using with drones. It is really kind of becoming how we build our existing data. It's got a wealth of data. It's got a very accurate data, and it allows you to have both accurate imagery down to-- I think it's 1-inch pixels, if not even more accurate.

And it gives me, as the designer, the context I need to then do the design in InfraWorks. So this is again another example of a rock face that was picked up, and then the 3D mesh that was created from that drone-flown data.

So what is augmented reality? I'm going to touch on what augmented reality is and what virtual reality is, because they're very different, and I think most people probably don't quite understand the difference between them. In fact, I didn't. When I got into it, I looked into the use of augmented reality and I kind of knew what it meant, but I didn't quite understand even what the difference between augmented versus virtual reality was.

So augmented reality is-- it's the integration of digital information with the user's environment in real time. So it uses the existing environment and overlays your design. So, as an example, if I had a design for the pipes in the walls of this room, augmented reality would allow me with an iPad to hold it up and see those pipes in context of the environment that I'm in. That's augmented. You are in the environment and you're seeing what your design looks like within that environment.

So how that works with InfraWorks. And I'm going to actually go into a little bit of how you take an InfraWorks-- towards the end, I'll go into how you take an InfraWorks model and how you process it to then utilize it with augmented reality. It's really easy. I think I put the process in the handout that I uploaded as well, but I'll touch on it towards the end.

But, essentially, with InfraWorks, you're able to use your model which is georeferenced, and you're able to be on site. So, for me, working on transportation projects. And the project that I'm going to touch on here today, it will be on site, on site visits with a client with an iPad, and walk through the model on site, before it's built, before it's been staked, before anything has been done on site.

So virtual reality. What is virtual reality? I'm not going to talk a lot about virtual reality. I'll touch on how you can take an InfraWorks model, very simply develop a virtual, what's called a 3D stereo panorama from an InfraWorks model. It's actually pretty cool, and it's very easy to do. So I'll touch on that at the end as well.

Virtual reality is the use of computer technology, such as an iPhone or a high-tech computer, that allows you to jump into your world. So, in this case, virtual reality on my project would be putting on a headset and actually being able to walk through my project where I'm standing right now. It's not on site, so it's not augmented reality. It's virtual reality. So that's the difference between augmented and virtual reality.

And, again, InfraWorks and virtual reality. With InfraWorks, you're provided the ability to immerse a client, a stakeholder, an interested party directly into the model and allow them to view and interact potentially with the design directly in a way that hasn't been possible before. And, again, it's becoming more prevalent in our industry, in the transportation industry.

So the simplest form of virtual reality, which I'll show at the end, is a 3D stereo panorama that essentially allows you with an iPhone-- oh, there goes my water. Too bad I don't have the iPhone 8, which is waterproof, huh? With an iPhone or with any smartphone to scan a QR code that me, as a designer, would create, and the model will pop right up on your phone. And then you can view it with any headset, a Google Cardboard. Again, I'll show what that kind of looks like at the end.

So I want to spend the majority of this presentation on the actual project that I've worked on, that I utilized InfraWorks on, that I utilized augmented reality on. I'll talk about how it benefitted the project, and really how we utilized it. So the project was the Mirror Lake Trailhead relocation project, located up in Government Camp, Oregon.

So if anyone's familiar with Oregon, it's up near the mountain. If you've ever been to Skibowl, it's a skiing area up there. It actually used to be the largest night skiing area in the entire United States. I don't believe that's still the case, but they do have a lot of nice skiing. Snowboarding. I don't ski. Snowboarding.

So the project was with Western Federal Lands. They were our client. What made this project challenging is there were a lot of very important stakeholders. US Forest Service-- the project was on their property. So Forest Service was very engaged in this project as well.

ODOT was involved because this project included highway widening. And then, of course, Skibowl, because the new parking lot, which I'll show, was an addition to the existing parking lot that Skibowl has there. So, again, a lot of people involved in this project.

So what this project was is a relocation of a very popular trailhead in Oregon, one that I've hiked-- and I'll show a picture of it-- that's currently located on the shoulder of the highway just west of Government Camp. And that existing location has been identified as highly-- a high safety risk, because it is immediately on the shoulder of a 55 mile an hour highway on a sharp curve.

And I've driven it many times. And, in fact, I've gone up there to park and hike that trail, and it fills up and you get people parking on the opposite side of the highway and hopping across. Not ideal when you're going hiking with your six-year-old. So it's been a safety risk for a while and it's becoming more and more popular. So this was a very important project for ODOT-- it's on their highway system-- for Western Federal and for the Forest Service.

So this is a quick overview of the project, the project site. You can see where the existing trailhead parking lot. It's right along the shoulder of the highway right there on that curve. And Skibowl parking area is right there. And then the new parking lot, we're looking to go right there.

And I think you can see it here, yes. So the lake that this hike goes to is right here. And it's called Mirror Lake because once you hike up there, you can actually see Mount Hood reflecting in the lake. It's very beautiful. In fact, there's a picture of the lake and Mount Hood.

So some of the challenges this project presented, and really why I made the decision, asked my project manager and said, hey, can we utilize InfraWorks from the beginning on this? I see it as, as we go through a design, being a challenge to understand, a challenge to really explain to these many different parties that have different agendas on this project.

So the decommissioning of the existing trailhead facility. Some of the elements of the design. We had a significant highway widening to US Highway 26. An ODOT ITS, an Intelligent Transportation System dynamic messaging sign. We had the new connecting trail that we were going to be constructing through US Forest Service land. The new trailhead and the new parking facility.

And one of the challenges and the concept, then, throughout the design was the avoidance of sensitive areas and elements. So we had archaeological. We had some environmental and endangered species. And we had a very, very important moss that we had to avoid and that actually really impacted the location of this entire project. And then a lot of collaboration with some of the local agencies, the sewage treatment plant immediately adjacent to the new parking lot, and then with Skibowl.

There is a picture of the existing trailhead. As you can see, ODOT tried to enforce no parking at times. That did not go over very well. And I don't believe that they enforce the towaway, like they've got shown on there.

But, again, this parking lot would fill up, and it would become unusable. You actually get people parking in Skibowl, which is about half a mile down the road, and walking up the shoulder of the highway to get to this trailhead.

There's a picture of me hiking. I hiked up there with my son. Beautiful day. It's an amazing hike. And it's actually a great-- I hiked it with my son when he was 5. And then I recently hiked with my youngest son, who was 2. And it's a great-- it's a family hiking. So, again, really emphasize the importance of this project.

So why InfraWorks and why augmented reality on this project? So there were three important reasons why I utilized InfraWorks and augmented reality on this project. Number one was the multiple agencies and interested party review meetings. We had these often. And, typically, in those meetings, there were anywhere from 20 to 25 people from these different agencies, from these different interested parties, that would be at this meeting, sitting in a room, discussing the project and what the project would like to achieve.

Challenging too, with this type of a project, what you can see on the right there is what would be a typical strip map you may produce and that you may roll out at a project meeting and talk about the project with that. What you see on the left is what I used. And this is a full 3D model InfraWorks.

So 2D strip maps just weren't cutting it. And I've experienced enough meetings with clients where it was hard for them to understand. And, again, some of the Forest Service folks are not typically looking at plans very often. So even for an engineer, it's sometimes hard to read a set of plans. So that's reason number one why I wanted to go with InfraWorks.

Reason number two is all the environmental, the archaeological, and then our Visual Resource report challenges with this project. So InfraWorks provided a cost-effective, contextually rich way to view the design in 3D relative to the surroundings.

Then the final one, which is kind of the main topic of this presentation, was the site visits, and how frequent those site visits were. And, actually-- I'll get into it a little bit more, but with the site visits, they were out there in the middle of the forest, and we did these site visits about once a month, maybe once every month and a half. And extremely challenging to actually talk about what the design is supposed to look like when you're standing out in the woods and you've got a piece of tape hanging on a tree and saying, this is where the new parking restrooms are going to go, right here.

So, again, augmented reality kind of brought a new way to do the site visits. So I'm going to dive into these a little bit more. Again, agency review meetings, which were very often. InfraWorks model ended up serving as our only form of discussion of the project in these meetings.

These meetings would be two to three hours, and I would typically run the meeting and I would have in InfraWorks, the 3D model, which was built and updated. I would update it every time we had a review meeting. I'd update it with our design data so that it was accurate, it showed all the design surfaces, it showed all of the context of the design.

So we could use it in the meetings. I would have it up on the screen, and I would actually zoom around and navigate around the InfraWorks model, and that would be our discussion piece. That would allow them the context to ask well-informed questions, to allow us to then go back and change the design. And it really kind of streamlined these meetings and allowed us to get past some of the fluff and some of the difficult questions that may arise from someone not understanding what the design looks like.

So it was our only form. We did not do strip maps any more. We did not do handouts. We had InfraWorks model up on the screen for three hours, and that was our agency review meetings.

The feedback we got from the client-- just as a heads-up, these meetings were challenging. I mean, these meetings were by no means easy, because, again, you've got ODOT, US Forest Service, Western Federal Lands, and other interested parties, all with different agendas. So there was a lot of challenges we had to get through.

But the design clarity that they received from the InfraWorks model allowed them, allowed this project to be successful. And, honestly, they said these meetings went about as good as they've ever been a part of for the number of people that we had in them.

So the number two reason, again, that we went with InfraWorks was the minimizing of resource impacts. Like I mentioned before, we did using InfraWorks on this project from concept all the way through design. This project, at the beginning, the conceptual phase, we actually were looking at multiple locations and multiple parking lots for where we were going to actually place this new trailhead.

So we had four or five sites, and I developed a very quick InfraWorks model for each of those sites, that, again, provided context to Western Federal Lands and allowed them to make an informed decision on which location worked best. It also allowed them to see what resource impacts they had. So I would overlay environmentally sensitive areas. I would overlay the archaeologically sensitive areas on the InfraWorks model and allow them to see what it looked, allowed them to select the safe and optimal location for the parking lot.

So these are three of the alternatives that we had, and this was the ones we'd actually selected where the parking lot was going to go. We had a location for it, and we had three separate alternatives for what the parking lot would look like. And, again, within each of these, I was able to also show what the impacts were to the environment. But, again, you can look at that and actually get an idea of what that design is going to look, and this is at a conceptual level as well, all done within InfraWorks, utilizing some of the design data that we had in our other software.

So the Visual Resource report. This was another very important piece of this project. US26 is a scenic byway, has very strict visual quality objectives as part of the forest plan. So part of our job as a consultant was to develop a Visual Resource report for how this project was not going to affect the visual quality of the scenic byway. So InfraWorks provided the basis for those visuals. It allowed us to provide images of the existing and the proposed, and allow them to see what the impact visually were going to be.

So I'm going to show some of the existing versus the proposed graphics, and these are final renderings that utilized pieces of the InfraWorks models. So this is the existing of the highway, looking to the east. And this is the proposed, showing the widening starting to occur, as well as the ITS sign up there.

This is an image of the existing, looking at the existing entrance to the Skibowl parking lot and looking to the west. And that's the final rendering, showing in the fully widened highway, showing the new entrance to the trailhead, and the new parking lot that's going to be built on the other side of the Skibowl parking lot right there.

And then, lastly-- and this will provide you a little bit of context for the challenges that we ran into on site visits, which I'll touch on next. This is in the existing parking lot. And so, again, this is actually on one of our site visits, and we're out there discussing where the design was going to be. And this is the final rendering from that same location of the parking lot.

So let's transition right into our site visits. So, on this project, again, we had an InfraWorks model from the beginning. I hadn't used augmented reality yet. It was new to me. I knew what it was. I kind of knew what it would do. But our first couple of site visits on this project, we didn't utilize augmented reality. We utilized what we had typically done in the past with site visits.

We had our survey crew take some of our proposed features and go out there and stake it in the field, put some pink markers on a tree, stake out the wall line and stake out where the trailhead was going to be. So we could go out there and, with the client, kind of have an idea where the project was, what it was going to look like. Kind of. Not really. Again, this is in the forest, a very dense forest, so it was actually very challenging to even find some of those stakes.

But that's what we did on our first site visit or two, which not only does that not provide you any context. It's also fairly costly to have a survey crew go up there. With how many site visits we were doing and with how often this design was morphing, and changing, and the items being added and removed, how often they would have to go up there and restake out new elements. So, again, very ineffective and really quite costly.

So these are some images of us on one of our site visits where we actually utilized augmented reality. That's me right there, and I've got the iPad up. So our first site visit, we brought a single iPad, and we had the InfraWorks model up on the iPad. And folks could, rather than-- on the previous site visits, we would be out there and they would ask-- we'd have a handout. They'd ask, OK, what does the design look like from here? Can you see the highway? There really was no ability to provide the true context of what the design looked like from that perspective.

With the iPad, multiple times out there, we'd be standing on location. They'd say, OK, where's the restroom going to be? And I could point to it. I could show them where the restroom is going to be.

Though, again, the way augmented reality works, what it's doing is it's placing me within the model. And this is simply just using the InfraWorks, InfraWorks app on the iPad. It places me in the model and allows me to see the view from that very location of what the design looks like. As I turn the model, the view turns with me.

So we'd be standing in the middle the parking lot and they'd say, OK, can you see the highway from here? And I could turn and show them what the highway looks like. I can show them what the visuals look like from the highway out to the parking lot.

And we even used it-- so part of this design was also a universal trail, which is an ADA-compliant trail, down to a bridge crossing of a creek. And we were able to use the iPad to walk the trail, walk the proposed trail with the iPad through the trees. So it really provided invaluable context to what the design was going to look like, where the design was going to be.

One of the challenges is there's a sewage treatment plant immediately adjacent, and they were very worried about not being able to save some of the trees, and what screening would there still be available within the new parking lot and the adjacent sewage treatment plant. So, again, with the InfraWorks augmented reality, you could actually walk to the edge of where the parking lot will be and show them. This is the edge of the parking lot. Those trees, we're going to be able to save. You're going be able to save the screening. So, again, context that is unlike anything you're going to receive from a typical site visit in this environment specifically.

So these are some more images of us out there with a client, utilizing augmented reality walking around the site. Let me show you on this next one. Just to provide a little bit more content for the client while we were out there, we did print out some screenshots from specific locations, that we handed them so that they can make some marks on it as we're walking through. And I could actually show them exactly where we're standing in this view as we were walking around the site. Here's another handout showing the trailhead, looking back to the east.

So we used this multiple times on the project. So once we actually implemented it the first time, we not only used it with the client when we were up there on site. We used it with the utility companies when we went up to discuss where utilities were going to be relocated. We used it with property owners when we were discussing what the adjacent impacts were going to look like.

We used it every time we went on site because it was the best way to see what the design is going to look like from anywhere on site. And once you have the InfraWorks model, I'm going to show you how you can do the augmented reality. It's really, really easy.

So some of the benefits of it. Again, cost savings. No survey staking of the design elements at intermittent site visits. Really sped up some decision making and allowed-- on these site visits, we typically would do a three-hour on site and a three-hour in office. So the context that they were able to receive seeing the design on site allowed them to then ask very deep and thought-out questions of the design moving forward once we got back into the office. So it allowed us to quickly identify even design conflicts on site.

And, like I mentioned, provides very concise design clarity, that simplified the public involvement process. It really enhanced the on site utility, right of way coordination processes. And then, honestly, it was just a lot of fun.

And for those that haven't used and InfraWorks, I would encourage you to try it. I taught myself InfraWorks. It was something that I saw as being a neat tool. I went home, and my son asked me what I was playing with. And I showed him. I said, I'm not playing. I'm working. He's like, no Dad, that's playing.

So then I started grabbing trucks and tractors and driving them around in the InfraWorks model and he loved it. So it is a lot of fun, but what's amazing about the tool is it is a design tool and I'm a designer. It provides me a way to really have fun and see what I'm doing in design. So just a little plug.

So I'm going to make sure that this runs. This is the final design visualization video that we created of the project. Let's see if it runs on a PowerPoint. Uh-oh. Hold on. It didn't pop up. There, I got-- I restarted the program.

Right. Good thing I'm prepared. One second. Why did I lose the screen? Technical difficulties. I was hoping I would get through the entire presentation without technical difficulties. Why is it not-- do we have a proctor in here? It's not reading my screen at all. Come on. Anybody?

AUDIENCE: [INAUDIBLE]

DANIEL ILIYN: Aha. Thank you. Now I can't see it. Let me pull back so that I can see it and hit play. Whoop. There you go.

So this is the quick fly-through of the project that we put together, that kind of drives from west to east. So I'll kind of talk to you a little bit again about the design. But this is what we showed, again, to the client. This is kind of what we used with the public. This is what we used in some of our final design review meetings.

You see on there on the right is a new relocated entrance. Skibowl parking area is up there. The new parking lot, as we're going to see when we come back around, is to the west of it. So we did a pretty significant highway widening, guardrail. We had a lot backfilled concrete barriers on the south side. And then tied back into existing over here on the east end. It's going to zoom back around.

Part of this project, again, just one of the many challenges is there were impacts to the existing Skibowl parking lot, which obviously was an issue. So in order to mitigate those impacts, we actually widened, significantly widened, a portion of their existing parking lot so that they had-- I think we added about 40 new parking spaces to their parking lot.

So that's what you're going to see here as it zooms around, and then starts to head back down the Skibowl parking lot to the west. So this is the Skibowl's entrance on the east end. And what you see here, the different coloration in the paving, is the widened area as well as a large barrier wall or a large rock wall.

And, again, you can see here we put utilities in, which allowed us to discuss with PGE and discuss with some of the other utility companies where their poles are going have to be relocated. So they're heading here back to the west. You're going to see the new entrance to the trailhead parking lot and the brand new parking lot.

So we added 50 spaces to this parking lot, which honestly is not going to fully satisfy the demand of this project, but a lot of the environmental and archaeological challenges kind of confined our project to that size. Part of the mitigation that we had for that was the sharing with Skibowl's parking lot, and then the widening of their lot as well.

So this is the parking lot as you head back to the west, and then the trailhead. So, again, this would be right in the middle of the forest existing now. Or maybe not any more. I think they've cleared it. This is in construction right now. I think they just finished up this season, and then they're going to finish up the design or the construction next season.

Don't ask me why I put a bunch of people in suits walking around. I'm going to blame that on some of the 3D models that were available in InfraWorks. We could all go and like this right now, right, in pants and suits?

Anyway, this is the ADA-compliant trail back down to the asphalt trail. And then I didn't take it any further, but we also added a mile, about a little over a mile of trail connecting back into the existing trail. So that is the final rendering visualization that we put together. Now let's see if we can get back into the presentation. Hang with me one sec.

Are there any questions while I'm pulling this up? I'm going to provide ample time at the end of this for questions, but.

AUDIENCE: Does InfraWorks have GIS locations?

DANIEL ILIYN: Yes. I'm going to show a little bit of that, assuming that this thing pops back up.

AUDIENCE: For your tree models, were they just out of the box [INAUDIBLE]?

DANIEL ILIYN: They were mostly out of the box. I did grab as many similar type tree models from other sources, like SketchUp, to try to give it better context for the environment.

So I'm going to skip ahead to make sure. So, on this project specifically, InfraWorks and augmented reality was a rousing success. The use of InfraWorks, the use of augmented reality with the Forest Service, with Western Federal Lands, and with ODOT, they all loved it. They spoke glowingly of it. They spoke glowingly of how this provides us the ability to know what the design is going to look like.

And, again, we utilized this software from beginning to end. So out of 50%, we had the InfraWorks model. And I've got those all saved too, so I can actually look back at my 50% InfraWorks model, see what the design actually looked like, see how it evolved from one stage to the next.

We've even used it-- I used it on the walkthrough with the contractor. So we had the first on site meeting with the contractor, and we walked through the site and I had our augmented reality and InfraWorks model up there to kind of show them this is the design. This is what it looks like. This is what it looks like here, here, here. So it's continued to provide us a lot of value.

My project manager as well as the project manager for Western Federal Lands called some of these site review meetings the best site review meetings that they've been a part of. They've been in the industry for a long time. I'm still pretty new to the industry. But that was a really kind of a glowing-- they spoke very glowingly of the use of this software. And, honestly, we're going to continue to use it like this moving forward on every project we've got. And several participants, again, spoke up about how easy it was to understand the design.

So now that I've shown you how I used InfraWorks, how I used augmented reality on a project, I don't want to get too much into the technical of InfraWorks but I do want to show you how, if you've got an InfraWorks model-- I'm not going to show you how to make an InfraWorks model, but I'll show you how to take it from a model and into augmented reality. And I'll also show a little bit of how you can leverage a model to experience the 3D stereo panorama, which is virtual reality.

So there's only a couple slides on this because it is really easy. So this is a snapshot of an InfraWorks model. What you see up there is a scenario browser. So for those that have used it, this tool is right here under the little TV.

And so if you've got an InfraWorks model, you pull up that scenario browser. And, essentially, you define the extent of the model that you want to create a scenario for. And it's as simple as clicking that button, clicking the extents, hitting Enter. And then you sync that model back up to the cloud. It is immediately then available to open up on the iPad app.

So I've kind of played with it a couple of different times and I've done different sizes of models. And I had good success with this model. It's fairly large. I have quite a bit of content in it. It didn't take that long to render it on the iPad app. So this is an actual-- so there's an app available for InfraWorks 360 that you can download on iPad or on a tablet.

When you log into it, log into it with your A360 account, any model that you have synced up as a scenario will become available for you to just click on, and it will open up the model. And you can actually see here on the iPad app, I had the model opened up. It was still rendering some of the texture. I think I took this picture three days ago, three or four days ago, from the iPad app, and threw it in here. They're starting to render some of the materials.

And then, from the iPad app, to implement augmented reality on site. So if you're on site, again, the model the InfraWorks model, has geocoordinates to it. So as long as you have an iPad or a tablet that allows you to use internet-- so you'll be site and you can, within the settings of the iPad app, once you've got the model open, just click Settings. It's grayed out right there, but it says Position and Orientation. You just click that button and it will immediately position you and orient you within the InfraWorks model based on where you're standing in the field. It's as simple as that.

So once you've got that, then you got it on an iPad and you can walk around and start to immerse yourself in augmented reality. So, again, if you've got an InfraWorks model and if it's located in the real world, which it should be-- and if it's not, you can always change coordinates. You can do that within the InfraWorks model before you export it out as a scenario.

But if you've got a model, you are set up, if you have an iPad or a tablet-- it does not work on an iPhone or a smartphone-- you are able to then take that model and go out on site and use augmented reality. Any questions about that?

AUDIENCE: For InfraWorks, did you have connectivity issues in the sites?

DANIEL ILIYN: That's a very good question. And, honestly, that is why I didn't use augmented reality on the first site visit or two, because I was somewhat wary of whether or not it would even work. Because this is a fairly remote site and we were walking through very dense forests.

I had minor issues at times where the positioning, where it positioned me, it started to lose it. And what I found is by clicking the Position and Orientation off and then clicking it back on, it kind of rebooted it and was able to find me and position me again. So I had to do that a couple of times when it kind of got lost in the trees. But as long as you've got service with your iPad, it should work just fine.

AUDIENCE: How do you deal with the [INAUDIBLE]?

DANIEL ILIYN: So it places you at eye level within the design. So, like in this project, that parking lot, existing ground is about 10 to 15 feet below the finished grade of the parking lot. So, obviously, when we were standing on existing ground, which would theoretically have been below the model, within the model it's smart enough to place you at eye level above the design, finished design surface of the model.

So, again, you're positioned geographically in the right location and oriented looking in the right direction. So it's intended to give you the view of what the model looks like from that position in the finished condition. Lots of questions.

AUDIENCE: Have you [INAUDIBLE] with a pretty heavy and pretty big Revit models?

DANIEL ILIYN: I have not. I haven't worked a whole lot-- most of the projects that I work on don't have significantly heavy Revit models. I've had some very simplistic Revit models that I've used, and it seemed to work fine. But, yes, that's something that I haven't delved into. Yes.

AUDIENCE: [INAUDIBLE] to the elevation difference, did you find any issues with [INAUDIBLE] understanding the [INAUDIBLE] differences, I guess, between the two?

DANIEL ILIYN: Yes. Yes, that can be a little bit of a challenge. One of the nice things that-- so it does position you within the model, obviously, at finished grade.

What I can still do with the iPad is I can navigate with my finger on the iPad. So to show them that difference, I could even push myself below finished grade of the model and kind of show them this is-- you can visually see what that difference is between existing and the model and finished grade. But, yes, I mean, that can provide challenges, obviously, if you've got significant elevation change. Yes. Other?
