Construction Layout Workflows—BIM to the Field and Back

PRESENTER: Welcome to Construction layout workflows. The purpose of the class is really to give you kind of an overall, if you haven't done it before, to really see a variety of the things that could be done with some of the equipment that you can see up in the front of the room. Our speaker here is Jarrod Baumann, very good friend of mine, longtime friend.

Knew him since junior high. He was kind of a jerk back then, but got a little bit better over the years. Eventually, was in my wedding. We've been coworkers in the same company and worked together on collaborative projects from different companies.

So Jarrod is very knowledgeable. He works Tilden Coyle. So they've been building in Southern California for 75 years, really a wide variety of projects, a strong focus on education a lot of the time.

So as somebody who works mostly for trade contractors, I always appreciate working for Tilden Coyle, both individually and as a company. They have a strong focus on really supporting their subs. So as a general contractor, they really are good to work with. So I've always appreciated that.

JARROD BAUMANN: Thanks, Joel. It's always good to know you've made a friend in life, right? Appreciate that. Like Joel mentioned, he and I have been friends for the last 15 years. We've lived about a mile apart too.

But he decided to leave the area. But I'll introduce Joel. He's the owner BimBoxBiz consulting for BIM, and really started with a lot of consulting to engineers, expanded quickly into field layout BIM models for subcontractors. So they happened to be on a lot of projects of ours, other GCs in Southern California. Joel's got a lot of experience with supporting just about anything to do with Revit.

Joel is always the guy I call when there's a complicated task to figure out. And usually between the two of us we can figure out the fastest way to accomplish it. And when it comes to the math and the trig, he's the guy to call.

So he's always the one there. Just want to poll the audience. Who do we have here today contractors? Let's start with general contractors, CM's, OK, good percentage. Subcontractors performing trade work of any sort? OK, architects, engineers? Other?

Am I missing a major category? Autodesk, sales, what else? Education, great, we have the privilege of having-- we have one of our very skilled interns in the class. He came out of high school from Bill Brown Santiago High School Corona, probably with more skills than most high schoolers. And so that program, loved to help out education side of things.

So his teacher-- he's worked with us now almost three years. So his teacher came back and did an externship with us in the summer and was working for Blair. But learning, working for us, we're learning from him what he needs to teach. So so good to know. Hopefully we'll cover some for everybody in here today.

Learning objectives, when you signed up, handed out, we're trying to show the things-- basically, I'm pretty much a newbie to this. About a year and a half, I've had total station, been using Autodesk point layout with our Revit models, our coordination models, trying to cover the things that were hard for me to find best practices for, best way to accomplish this, to go in and out, back and forth from the field. How to work with your surveyor and project control.

And then just a quick discussion of the hardware, because, frankly you can get more information by going to the exhibit hall and talk to them all, like a [INAUDIBLE], you name it. They all have good products. And they can accomplish most all of this.

Obviously, you always want to look and see what's most compatible, what works really well with AAPL and BIM 360 Layout, if you're using it. Last, that whole round trip, how do I get points in? How do I get points out from what I've created or what's yet to be built?

So a few slides of the benefits. We're going to get right into the software. This is a hospital project. The entire sample you'll see today, pretty much hospital project except that scan you saw in this room that we'll show at the end.

Superintendent on the right, he's the guy looking at the other two, the project engineer and project manager, and, like, why aren't you back in the office doing you're doing your job? When are we going to get this done? But they called because where they're standing is where the ER addition goes.

And there's lots of things running underground. And they were starting to dig. Now, you can pull tapes all day long. You can take pictures.

We already had GPR paint everything on top. But until you know exactly where it's at and what depth it is, you might have problems. And sure enough, what you're not seeing there is about three more layers deep of utilities all serving the main hospital now have to stay active, cannot shut down. So we have to know right where those are, and start planning. What does that mean before we go to over x this site?

So benefits-- grabbing those points, literally spending a half an hour, an hour, two hours in the field grabbing those points, bringing them in, tells me that I can put in all those utilities exactly where they are per the slope. And they became a problem, as you can see.

Some of these that had to stay these relate right into an RFI we put in, 2D sketches 3D views, saying, how do we accomplish this? Here's your OX requirements. Here's what has to stay intact.

Can we encase? Can we do something? So site conditions, one of the biggest things we use it for, existing conditions as you're discovering stuff.

So no matter how good the civil engineer did, finding everything that was visible and using those as-builts they had, always when you dig up, something is different, as you probably many of you have experienced. Another one-- QC for not just-- we don't self perform hardly anything. It's all subcontractors.

So you're looking at a small, make-ready utility building that's serving the new ER addition. You've got the plants right on the ground there they're laying out. That's only about 25% of the conduits that are going to go in that space you're seeing in the picture. And you can imagine how difficult it is to get all those in the right place. Everything has to meet up to a piece of equipment, come up a wall.

PRESENTER: It's a little tough. As a trade contractor, I hired a surveyor to go out and mark the ground. And now all the dirt where my paint was is gone. So how do I ensure that I'm really hitting the spot that I need to hit?

JARROD BAUMANN: So, clearly, from a subcontractor's perspective like Joel was saying, for them to have this tool would be awesome. But since I have it, why not help them to be more successful in the process? So I go out there during that picture you saw, start shooting those equipment windows, those little templates you see of wood that they're spiking into the ground four or five feet down trying to get these things right in the right place with string lines.

In about an hour's time, I shot everything they had, brought it back. So Joel's company actually did this electrical model for the subcontractor, BIM Consultants. So they do fabrication models, et cetera.

Project manager Jared is in here today. And, basically, just sent him back, these are the ones that are a ways off you might want to correct before you start running into trouble. So just those points that I shot, you can see here the equipment window where it was supposed to be according to his model, and where it was ending up.

They were doing a really good job. Most everything was pretty accurate. But there was a few that were needing adjustment. And they were ready to go. So that can be checked during and then right before it's poured.

Another example of it-- a quick shot when it's brought back into the Revit model. You can see the alignment of this communications vault. It's a little off. But it's in a parking lot, not too big a deal.

But biggest thing we wanted to point out is finished surface was 760.54. That's where the slope drainage was going to be. And actual lid, 760.29. So we came to discover along the way that our surveyor was having a little trouble with his benchmarks, his elevations.

His finished surfaced of the pad, he wasn't actually given us the right elevations, because he didn't have an updated RFI which said what those were supposed to be. So things that were starting to get put in-- we would have not found that probably until the day we poured this parking lot and started grading it for slope to know that they were going to have to either lift it at a riser or ring, et cetera.

Now, small problem in this case. But it worked in the bigger ones when it came to elevation of depth of vaults that had conduits going under footings. So literally, again, probably two to three hours invested time, going out there, bringing it into the model, we were able to give them that info.

Another benefit is we've owned and operated a feral laser scanner now for it's going on 3 and 1/2 years. We rented one prior to that to say that we wanted to use it. But now that I have the total station, and APL, and can set up the coordinates, dropping these laser scans in with survey point precision is the best, because normally we were aligning them manually.

We were going in and saying, well, the face of the CMU is supposed to be here. So that's where I'm going to put this laser scanner. In all actuality, that's not necessarily where it's at on the site. If they miss the mark when building it, now I can shoot targets while the laser scanner is running, bring that in with survey control with just a few clicks.

And as you can see, this is that laser scan. This is like an intensity view from Autodesk ReCap. We just shot in black and white, no color. But you can see the grout lines.

And, basically, after we shoot this, we check the walls for level. We check the embed plates to the distance between embed plates so that if steel needs to adjust prior to coming out, they can. We can check all of that.

And you can see the accuracy. You can find the deck angle, everything, in that scan. But the fact of knowing that it's in there precisely per survey coordinates is the best part of it.

Last, today we're going to demo points in, points out, how it works, how it works with the machine, BIM 360 Layout, et cetera. So those are just a couple of shots from the iPad that, basically, you would call the data collector for when you're running APL through a Wi-Fi connection to the total station.

So that's it for PowerPoint. I like to keep that short, and get back to in the software. Any questions up to this point, before we get rolling? In the back?

AUDIENCE: [INAUDIBLE]

JARROD BAUMANN: Absolutely, excellent question. So I learned how to read a grade stake, the fastest on this project we're seeing because when I started doing the math what's written on the great stake and what I was shooting at the subgrade, the math wasn't working. And, sure enough, that's when we discovered the surveyor did not have the RFI that changed finished floor elevation.

So his finished grade was five inches high. They had to regrade that small utility building. Communication error on our team's part-- they're not checking for the latest. But that machine, as inexperienced as I was, found it for us right away.

And before we were too far in the game we got the grader back out there and fixed it. So, yes, and we're going to go over control base point, all of that right now. We're going to jump into that in this model.

So this will kind of follow the handout from this point. We're going to try and discuss this. So point layout in your Revit model, the question was asked about the Revit base point.

So by default, I've got my sight base point and my project base point right on top of each other. One thing that I find that even a lot of experienced Revit users don't know is they know they can acquire shared coordinates, might have got models from the design team with shared coordinates. They don't realize that you can make multiple sets of those.

So in the Location tab, under Site, by default you have internal. That's what a Revit template has in it. If they've acquired shared coordinates, it's going to have manipulated the survey point of that internal coordinate system.

But as you can see, you can duplicate. So right off the bat, when we start we have two processes. We're doing site stuff with our total station.

We're doing interior building coordination with subcontractors. I usually make a BIM coordination origin. And now, I have two. I set it current.

I move my shared coordinate point to the grid intersection everybody agreed to work within. So our MEPs within the building structure, they're just worried about that grid system, and the overhead MEPs. And that's the origin. So I can bring in and out export models for clash detection, whatever, with just grid intersection, A2, finish floor is zero, simple enough.

And you do that by using, up here, coordinates. You can specify coordinates at a point by clicking on a 3D object, tell it that's 0, 0. I could do that simply to set that origin point right now.

This view is locked, sorry. So, for instance, my origin marker for BIM coordination is here. Isolate that element. Remember which one I set current. BIM coordination origin, I'm going to make this one current.

Notice nothing changed. I'll specify coordinates at a point. And I'm going to make this my zeros, because that works really well to now have an origin. You'll notice my survey marker moved. It's reporting 0, 0, at my grid intersection. All my internal building BIM models come in.

What about for site, survey control? It starts with good horizontal control from your surveyor. That I had to learn. And that's a process, because you're going to get plans with good horizontal control on them, and ones with bad.

And you're going to have to get the info from them, one way or another. So I show this as an example of good horizontal control, if that will open up. Civil engineer did a great job of giving us grid intersections to all of these buildings.

Now, you'll notice there's corrections in red because it didn't match up to what the architect had. These buildings all connect with steel. So the grid system does have specific dimensions between buildings.

So we had to make a correction. But at least they were prepared to answer the RFI, and say, yep, our grid layout wasn't coordinated with architect. These new numbers are good.

That's what you're going to use in the field. So this is a good example, in that they tried to give us all the information they could for layout. Bad example is the project that we're demoing today, we had to ask the question.

All we got was building coordinates at building corners of the existing building, nothing to the new building addition grid, not at all. So when I open up the attachment that we made, we basically went in and said, based on what you've given us on the plans, here's an overlay of civil.

We have those building corners at what you specified. Here's what we're assuming the grid intersection northings and eastings are, please confirm. And the answer was, confirmed. So we get their civil CAD files. It's got their coordinate system in it. We can start exporting the grid from the architectural model, checking everything, making sure it's all set. And once we get that confirming RFI, we now have solid information as to where this building, these building grid intersections, are to be placed in the field.

So back to Revit-- I'm going to make one more coordinate system. So you recall, I have two in here now, the project internal, the way it came from the architect. I have my BIM coordination origin.

I'm going to now create one. But I'm going to use Autodesk point layout. And the benefit of that, the advantage, is that it sets true north orientation as well. So you're fully synched up to civil, horizontal control.

So let's take that RFI we just had open. We're going to go to Autodesk point layout. It's already logged me out of my license. There we go.

So you'll notice on the ribbon here, coordinates. Create a new shared coordinate system for known points. So we're going to follow this.

The numbers I have are in decimal feet from my civil engineering plans. I'm going to snap to the work plan. I want to snap at the grid intersection, level one in my Revit model. It's good enough for me. I don't need an element to snap to. So I'm going to use work plane.

Flipping over, grid intersection A2. So if you're familiar with northing, easting, x and y. So easting is x. Northing is y, at least right hand Cartesian.

We're not going to get into that. It gets too complicated otherwise. But for typical for us, Southern California, California, we're using a state plane coordinates. Or in this case, it's a more local coordinate system.

x is easting. y as northing. Of course, z or h is our height.

So first number I need here is 5027.123. So I'm going to go back over here. I'm going to click my marker. Notice I already have a coordinate elevation. I have a little marker I use.

So 5027.123, because it's asking me specifically right there, x, y. That's the order APL needs. Comma, let's go back, 4602.674, Hopefully, I don't type these in wrong and make this demo take longer.

I'm going to zoom. You'll notice in the handout it says that there's a tip with regard to what points to use. Notice I'm moving diagonally to the farthest extent that I can, because that gives you a longer distance to check your accuracy, your math, between these two points.

So here's my next one. Currently, it's only 150 feet away from the survey point. Same thing, back to my confirmed RFI grid intersection there, 5237.803.

Again, x, so then y, and 4564.472. So I could demo, and just change one of these numbers by a foot. And I would get a dialog box that shows there's a deviation of a certain amount.

In this case, I don't get that dialog box. You'll notice in the handout it says, drawing points versus new points have a difference in the lengths of 0.18. Well, 0.18 decimal feet is about two and an eighth inches. That's not good enough.

You don't want to be two and an eighth inches off on everything you shout out there. So you would know it if your architectural grid, civil coordinates, don't match up. That's kind of one of the first places you find it.

In this case, though, they sync up. The math works between them. And I'm going to call this civil horizontal control.

Now, that is the control that I'm going to use to sync my total station up in the field. Maybe you got a civil engineer or surveyor originally that doesn't want to give you those points. They want to give you new points with their own coordinates.

That's fine, as long as they give you something to relate it to in the building, and an offset to the grid so your model relates to the points in the field. I'm going to set this one current at the time. And you'll notice immediately that building grid intersection updated to the coordinates that we saw on this.

So we have created an additional coordinate system. Again, manage, location, site. Now I have not only my internal, left it the way I got it from the architect, civil horizontal control, and BIM coordination origin. All of these I can switch between and export things based on whatever task I'm doing.

And you notice right here, though, this is one of the benefits. It's rotated to true north. So you can specify coordinate at this location. But it won't give you the True North rotation. You have to type that in manually. But it's important because, obviously, you're not going to sync up to anything your surveyor gives you.

So everything I just showed you applies to if you don't own a total station. If you have a license of APL, and you want to hire your surveyor, which is what we did at first and wrote into their scope, I need 1,000 points from you throughout this project. I'm going to tell you when. We'll say five move ins.

And I'll get all those points at those different times. He gives you those coordinates in a text file. They can come in. You still have to set up your Revit model this way.

But it will align. And they will sink in. So it's an important step in that regard. Let me see where I'm at in here to make sure.

So let me show you why, again, that's beneficial. So I'm going to go to this 3D view. I'll make it large.

So you have the ER addition. And you have the make ready utility building, and that laser scan I showed you of the CMU walls. Now that I have that current coordinate system set, I'm on civil horizontal control.

When I was out there with my laser scanner, I shot three targets that that scanner can see. And I shot them on those coordinate system. When I bring it into ReCap, that creates an origin that matches my horizontal control on my site.

And I can simply come up here and say, insert a point cloud, after literally half an hour of importing scans into ReCap, putting it together, import a point cloud, make ready CMU walls on that date. And this is very important, auto by shared coordinates.

The coordinate system that's current in your Revit model at the time is what it's going to use. So you need to make sure that that one's set, not your BIM internal coordination origin. Hit OK. And immediately, you can see that's dropped in exactly where the design wanted it.

Surveyor gave them hubs to lay out to. They used string lines to start the CMU. And they did a pretty precise job. I'm going to change this to an intensity gradient.

So you can see the detail now. We produce about 60 sections in here of every embed plate, deck angle to check it, CMU walls to check level. And these guys did a precise job.

They were only about a little over 5/8, 3/4 of an inch off on their starting wall face of CMU. So the whole building shifted west about 5/8 of an inch. That's it, overall.

So everything else is on the money. And trust me, the time it took, and the confidence you had in getting a laser scan and then bringing it in and manually aligning it, you're just aligning it to the model to check other anomalies perhaps. But you don't know real world condition and location without this process.

And so now, we can go out there. We can send one of our younger guys who knows how to operate the scanner and nothing else, somebody to shoot him the targets, bring it in, highly beneficial in that sense.

Any questions on that, setting up that coordinate system, before we move on to the next section here? How are we doing on time, Joel?

PRESENTER: About five long.

JARROD BAUMANN: Say again?

PRESENTER: About six minutes long.

JARROD BAUMANN: OK, well, we can answer questions at the end too. So handout goes next to the hardware itself, because from here, just a little bit about the hardware. Right in front of me here with the tripod data collector on it, that data collector works with Leica's icon software.

And I can go out there and shoot as many points or layout as many points as I want. Not required to have BIM 360 Layout. In order to do that, that data collector will accept points that I export from Revit, and then collect new ones. And I can bring those in.

But it's not immediately connected to my Glue models, and to all my 3 models that I have for coordination. Whereas using the iPad as the data collector and the app as BIM 360 Layout, I have immediate connectivity.

I control the robot with it. I'm looking at a 3D model. So if I come in there, and simply bring up a couple of those images, my models that I've uploaded to Glue are available in BIM 360 Layout, sync them to the iPad, then connect to the Wi-Fi controller of the iPad. And that is the data collector. And it runs the total station.

So you have the 3D visual there, which is very helpful. So the day I helped the electrician out there with layout, he'd asked me to come out. I didn't pre-layout the points. Saw what he needed, went into the office, put some points on all of his equipment, synched it to Glue, went out there with the iPad, ran around, checked them all, gave him deviation as I did it. Came back, and gave him that sketch out of the Revit model as well.

So we ended up choosing Leica because, one, I had a great surveyor who was getting into selling equipment, wanting to get out of the field, who taught me a lot of things that I needed to know from a surveyor standpoint, how not to screw up with this stuff. He liked Leica. He actually got me a demo model, which saved us a lot of money.

And it's solid equipment. That data collector there that you see that's the tablet, it's fully able to take an IFC export of my Revit model. So you can visualize in 3D on there.

That's a Windows 10 tablet, pretty powerful, good battery life. So there's some good tools on that too. But, again, I don't need to talk more about it. Just go find out what equipment you want.

Some guys want to start simple. And that's what I recommend. If there's a less expensive version and it gets the job done until you learn this process, likely if you're a large enough company, you're going to end up with more than one of these. Or somebody is going to be running around with that full time and be an expert at it.

PRESENTER: There's a wide variety of vendors down there. Topcon is closely shows associated with Autodesk. Leica is down in the exhibit hall. Trimble is kind of the gold standard. They've been doing this probably for the longest and with the most variety of hardware. So, really, go visit the exhibit, hall, and just talk to them. And choose what's best for you when you make the purchase.

JARROD BAUMANN: And so total station, or instrument sensor, all those terms are used for that. You've got the pull. You've got the prism on top of it. That's basically what the robotic total station will follow as you walk around. It's important to know that.

And then we talked about data collectors. The rest is kind of miscellaneous hardware, tripods, bipod legs. I'm going to open up one additional copy of Revit to show you now the next section in our handout of how you actually lay out points with APL, how you get them to Glue and into the iPad.

So I'll run through this one pretty quickly. I'm going to open-- something to know about this model here. This is a model that I start with on every project. This is an empty template of ours that every model is linked into.

I do not start with architect's architectural model or any site model they had. It's my own. Everything is linked in. This building sits at finished floor. So I actually use true elevation.

So if you look, in an elevation view, there's a level down at zero. And I call it civil base, zero. And I make a level called 763.5 finished floor. And that's where my Revit model goes.

So when I want to draw a pipe in a view, I can use true elevations right off the civil drawing, no wasting time with it. So that's important to know. Now, does that mean, though, that I can only layout points on things that I've authored in this model?

Not at all. This is the architect's architectural model that I got. Maybe you don't modify those at all. Maybe you get updates from them.

I don't know what the arrangement is. You can add points to a linked file. As long as it's linked in here properly where your coordinate system is setup, they'll export out to Glue.

So you'll see, I already have a few in here. And this other copy, I'm going to go ahead and open up the architectural model. So we'll bring that up.

And I'll show you how to layout points with one of the tools. Now, there's a number of tools, as you see from the handout-- duct hangers, nesting points inside of families. There's pretty good information in the guide for APL. There's also the forums is probably one of the best places to ask those questions.

But all these tools work really well. I'm going to just demo adding some points to wall base, as if I'm going to lay out stud lines, or check stud lines, for our framer. So you can see the few that I'd already done in there before. I'm going to add some more, though, on some of these other walls.

Again, this model, I got it yesterday from the architect. It doesn't have to have the coordinate system. As long as I trust the grid system in it, and this is the layout that we're supposed to be building to.

So I'm going to go to layout. And I'm going to use this wall layout tool right here. It already knows I had done 55 points, or 54 points, before. I'm going to use a custom description because this is going to be stud face.

And here's a bunch of options. And you just play around with them until you get what you want. I might want to check that the wall is true by having points at the top of the wall, where it meets the deck, and at the slab. So I can tell it to add both.

This is a very important one. And I kind of highlight all this in the handout. Track-- that's the structure, or the core layer, as we know it in Revit. So, normally, we take the core layer. And we say, it's a four inch metal stud.

That's where I want those laid out. That's really what I care about, finishes are derivative of if the stud got in the right place. I'm going to select just some of those.

It's going to start my numbering off on what it remembers from last time. So I have pretty much most of my options here set. I'm going to say, bottom only, hit OK.

And so now, this is a multi-select here. So I can simply take a bunch of walls, if I want, finish my multiple selection. And as long as I have all those settings right, you'll notice it's going to generate at every single end and corner points at the core layer.

And I could come through, and start eliminating some of these. Like, that's one wall. And the wall joins in Revit, make another one. I could just eliminate that one if I want, just to minimize. But, really, too many points don't matter too much. You can choose which ones to shoot in the field. Question?

AUDIENCE: [INAUDIBLE]

PRESENTER: For the recording, the question was, he's working inside the architectural model, not in the site model.

JARROD BAUMANN: Right, thanks for repeating that, Joel. I cannot select walls in the linked model with APL. That's correct. So I do have to come in here, regardless.

But some people think that that means I've got to set up the coordinates in all these different models, and be able to export right from this model. No, I can come in here, just put the points in, go back into my other model, which I'm going to do now.

So I'm going to synch it, save it that is, wait till it's done here, switch over. So I'll go over to one of the areas where I didn't have anything, reload this model. And you'll notice, this is my named view points export to 360 Glue.

Now, I'll probably have a dozen of these in my site model. Maybe it's just showing only my electrician's model, and points that I've put in that. That's what I want to export to Glue so that I only have to work with one model sometimes on the APL layout. You can put them all in there.

You can put all the linked models, show all the points in one. But chances are, you're trying to simplify it for whoever's doing your layout. So you notice, I have a bunch of new points in here kind of hidden in the walls.

Tip in the handout-- make a filter that finds these. They're little. Fine detail, get some colors, so you know what you're looking for. Those are all in there now.

So I have additional points. And this is my 3D view. It reacts to section boxes.

I'm going to turn this off, so we don't get a long export to Glue. Glue doesn't handle the point cloud anyway. There are ways to make that work.

But at this point, they're still working on full support for that. So this is my 3D view. My linked file is reloaded.

And I'm going to simply go up here to the add-ins, and the Glue It button. Couple important things in this dialog box-- first, it's going to be your log in, of course. So I'm going to go to our server, the project we're on.

By default, if your view is named, and this is your current view, that's the one it's going to choose, which is the fastest way. So have that view open. And have it named what you want that file name to be on Glue.

So you'll notice, if I just scroll down, the only one that's selected is points export to 360 Glue. And like I said, I would normally name this wall points export. And the only Revit Link in this model that I'd have visible is the architectural.

And I hit next-- lot of good, important options here. First of all, go to More Options, Shared Coordinates. Absolutely, that's the coordinate system we set up. And it has to be current.

It's simply using the current coordinate system. Hopefully, in the future, just like with APL, they'll allow us to pick the various coordinate systems in there, and say, go with that one, so I don't have to remember. Because I would have to cancel out, set my horizontal control that we set up earlier current, and then go back here.

I know it's still current, though. I don't have any construction parts. So I can include or not.

Obviously, this one is very important. If I don't export with the linked file included, I'm not going to get any of those wall points, because that's where those points are at. You can include rooms. Obviously, we're looking for more support of other things from the model by default. But as far as geometry goes, you'll get all of this.

TTwo formats you can choose-- DWF or NWC. We typically use Navisworks cache files for all of them. It's already named, same as my 3D view.

It already knows the folder, because I've done this before in case we had some hiccups. But you can choose the folder where it goes. And I'm just going to say, Glue It.

So this will export, just like in Navisworks, export to NWC. What you see is what you get. So this section down floor plan view is what Joel is going to see on the iPad.

It's going to go through the process. It's going to upload it to Glue. And it's going to tell me, I'll get a message when it's finished gluing.

So while that happens in the background, we've already got it downloaded to the iPad. It knows that this model was updated before. Do I want a new version of it? It will version it to a different name.

No, I just want to update this one. So, again, I can just keep coming in and doing a different part of the building. There's some other good recommendations in here about dividing your multi-level building into section 3D views, just so you can do it level by level, and name them accordingly. So I'll get a notification when that's ready. But in the meantime--

PRESENTER: Yeah, some of them some of the most exciting stuff is actually seeing the hardware move around. So in preparation for this class yesterday, we used the scanner. We scanned the room. Last night, Jarrod put in a couple of control points.

So, for instance, in this room what we did was is we can easily see the color changes on the carpet. So we used some of the corners there as control points. We also shot a couple of the decorations around the room.

So anyone who is real close by can see there's a few points here on the iPad already existing. But the nice thing is the whole idea is it's about the round trip. There's information you're going to have in the office that's better than in the field. You want to be able to send it to the field.

There's information you have in the field that's going to be better than what you have in the office. So you want to get it back to the office. So just maybe to demonstrate that piece of it-- so I don't know if you can see the red laser over there on the wall.

But we have this one, the location of this decoration already stored in our model. Let's say we wanted to locate this. So maybe in real life, this might be a fire sprinkler location. It might be a wall penetration, an embed, something like that you really need to grab hold of.

So you can get it closed just by eyeballing it. And then there's an enlarged zoomed in option here. So I can very clearly see-- I'm in the dead center of that little piece of decoration up there.

So at this point, on my data collector, all the coordinates are dialed in. So all I have to do is hit this Collect button there. And I now have an option to name that point, pick what's in that location.

So this is, in this case, a finished wall. And it's point number 602, 603, I think.

So finish wall decor would be the description over on that far side. So a quick description typed into the iPad, hit Save. And now, that point is stored in the location. Then when we synchronize Glue, you can see it comes back into being available on the laptop.

JARROD BAUMANN: And so we're moving a little faster, that we'd hope to be able to show you how you sync up with the machine. So if you look here just for a second, since we've got a few minutes and then I'll show you how that comes into Glue. You saw how we uploaded a model with points to Glue.

So just quickly, to get a common coordinate system for this, we just scanned this room, used the origin of the scan, didn't scan any targets, and simply came in, like Joe said. And we laid out points, because the scanner sees with enough detail, I can get very close to where the carpet color changes.

I laid one point. It takes two as a minimum to sync up the robot, laid another one over here, and posted that to Glue. That is what Joel opens up with APL, goes into BIM 360 Layout, and syncs that model down. That's what he was showing you in the different screen shots there.

We drew a couple quick walls, as you can see, just so we added orientation of the door, wall. And then when we first sync up, we have to use the reflector, the prism, set right over that change in color on the carpet, shoot that as control point number 500 that you saw here, shoot the other corner back there as control point number 501.

Then the machine knows its location. It's triangulated. It's done the math. And I forget. Just by using the carpet and the laser scan, how accurate were when we synced up?

PRESENTER: I think it was 1/800 of a foot.

JARROD BAUMANN: Yeah, and that's not a target that it centers in on that type. That's using the color and the dots from the laser scan in this room. Granted, you would never want to use that over a large bunch of scans registered together, unless they were all with survey control, but just demonstrates simply those options.

So after Joel has shot everything he wants in the field, did we want to shoot one more? Do we have time? We've got about 15 minutes.

I think we could shoot one more of these chairs, to see how different it is. Can you switch back to the prism? So it will have to search. Just aim it right at it.

PRESENTER: Which model do you have?

JARROD BAUMANN: We'll actually just shoot another one of these blue dots that we've never shot before.

PRESENTER: NPR or GRZ?

JARROD BAUMANN: NPR 122 is the prism type. So as layout works with multiple different prism types from Leica. I'm leveling this up. And, again, the more level, the more accurate.

If you can imagine this poll was 100 feet tall and I was slightly off level, my measurement would be a lot farther off. The lower, the more accurate. When you're syncing up to control, the lower you can keep this, the more accurate, because any little bit of out of level is going to be measurement error. Just go and point it at it manually.

It will probably find it somewhere in there. There's a couple of different tools to search. I'm making Joel do it as a demonstration of, he's only used this twice now?

PRESENTER: This is twice on this machine.

JARROD BAUMANN: So it's not hard to get used to. He's only used BIM 360 Layout running that total station twice in the last couple of days. So it's really not that hard when you learn the tools. So it's synced up.
