Scoring a Home Run Using the BIM 360 Platform in Constructing a Baseball Stadium

PRESENTER: Well, welcome to CS 119 263. If you're looking for how we built the football stadium, it's down the hall. So, no, I'm kidding. So this class is called, Scoring a Home Run, how we built a Cleveland ballpark using BIM 360 Field and Glue. We basically had a paperless production, so we did everything on computer on this. And it is time to begin.

So who's ready to play ball? OK, got a few. All right, so again, welcome to AU. How many first-timers have we got? Good, well, you guys keep coming back, and soon you'll be a veteran like me. I think this is my 13th AU. How many have you been here, Larry?

AUDIENCE: A lot.

PRESENTER: A lot. So yeah, just keep on coming back. And it's always something, and it's always something fun. I hope you enjoy baseball, because we're going to be filling this class with makeshift baseball players, like me. So I'm not really a Ranger's fan, it was just my wife bought me the jersey for my birthday, which is today. So when you get to the end of the class, fill out the surveys--

AUDIENCE: Happy birthday, Norm.

PRESENTER: Yeah, no, I'm BB-- I replaced Norm. OK, so let me turn off some of the stuff here. So this is kind of some drone shots we took of the baseball stadium, it's opening day. It's a minor league stadium, there in Cleburne, Texas. It was also, opening day was my 32nd anniversary, my wife was very gracious and went to the game with me.

And as an apology, I bought her earrings and necklace. So got to make up. And so we built the number one independent baseball league in six months, so we took the stadium, built it in six months. And so that link right there will take you to this-- boy, my mouse is not working. There.

OK, so that's the write-up we had of the stadium, 1,750 seats in the stadium, plus all of the burn areas-- sit on the grass, have some fun. Bits of some fan appreciation. Again, I ask first-timers, y'all wave your hand. Who has come from the greatest distance?

OK, right now, it is 2:15. At home, is it 2:15-- not Vegas, but 2:15 AM, who's from-- OK. So you're from Dubai. Do you want watermelon or grape? Watermelon, all right.

See, she sat in the front row, and she gets-- you know. If you answer the trivia question, I don't know you. Thanks for coming, thanks for being here. Some of the free time that you're going to have at AU, hopefully will be filling out my survey. Let me know how I did. If I'm doing a bad job, get up and walk out-- I don't need your survey.

[LAUGHTER]

Kidding, I'm kidding. So welcome to Autodesk. Again, if you're first timers, take some free time to yourself this week. Go outside. The next thing you know, you'll look up and it'll be Thursday evening, and you haven't been outside, and the sun will still be there.

All right, so player introduction. That guy in the sweater, that's Norm Aiken. I replaced him. I am BB Star, and my friend back here said that meant baseball star, so we'll run with that.

So the Astros just won the World Series, in case anybody has been asleep lately. And if you're a Dodgers fan, too bad, better luck next time. Well, I do have a box of tissues around here for Dodgers fans. Or I saw the therapy dogs downstairs.

All right, so I was just walking down the hall, minding my own business, thinking I'm going to the batting cages, and the Autodesk crew grabs me, throws me in here and says, you're going to teach a class. I'm like, OK, that's fine. I know Norm is my biggest fan, he's always watching baseball. He'll go to a restaurant and sit where he's watching a baseball game. And if there's not one on, he'll give the people there at the restaurant a tape and say, hey, play this game. I know who wins, but who cares.

Now, the reason why I sent Norm to the minors is because he ignored his wife on their anniversary. All right, so the purpose of this class-- and you'll see, here's our team from 1922, that's the Rock Island Railroaders that were in Cleburne, Texas. Here's the modern team on the right side over there.

So in 1922, the Railroaders left Cleburne. 54 years ago, the Railroaders started playing as the Astros, and it took 54 years for them to win a World Series. Maybe they need me on their team to get a little better than that.

But what I want to tell you, why do we use BIM 360? Well, first of all, anything baseball, I'm there. It's my favorite subject, other than, of course, myself. The project was a fast track last AU. I was sitting in a class just like this one, and I got a phone call, and they were saying, well, we need to have a coordination meeting on the stadium.

So I found a quiet place, which there isn't one around here. Maybe downstairs, deep, deep downstairs. Anyway, so we mobilized a team on December 16th, and May 17th, where we're playing baseball. So we did a ground-up stadium, fast track, did it all paperless.

And some of the challenges that we had, or to summarize what we did, we're going to say how AECOM Hunt, we used BIM 360 Field, BIM 360 Glue, Ops, and Docs, to create the stadium. We did it paperless. The American Association's-- copied it from that article, so I'm just going to skip over that just because it's boring.

But some of the challenges we had in building this-- fast track, ground-up stadium. When we went to the site, there was nothing there but a field. The police chief was really excited because that field was used a lot of times for drug dealers, or something, it's a small town in Cleburne. What kind of trouble can there be?

The subcontractor base-- they were not trained on BIM 360, Field, Glue, Navisworks-- some of them were barely trained on AutoCAD. So that was one of our challenges to build a stadium this way. And then, there was no room for error. When we did the contract, we didn't put any extra money in for weather, or any type of contingency.

So we were really tight on the budget. And we had to come in within budget. So what we looked at, and get to our spring training objectives-- if you look, there's an acronym that's spelled out, it's called DECK. Determining the needs of a team, educating their subcontractors, coordinating the process, and knowing how to link between the programs.

Deck is a baseball term. Anybody know what deck means? Who said that first? You? OK, you get the grape. That was an error, see, he missed it.

But yeah, the next batter is up on deck. Or maybe we're in Vegas and we're all playing cards. I lost $65 to Larry last night playing poker, so over 10 years, that's been $650. So I figure he owes me something.

So we put that in there. But we're up at bat, we're ready to run the bases. The first objective is to determine the needs of our teams. Any good scout's going to say, well, what's he need? Is his shoulder still messed up? Or whatever.

And then we evaluate the team by setting up the objectives to say, how good is your team? What training do you need?

After spring training, we want to train the base, the subcontractors, on the programs in order to use. And who uses BIM 360 Field in here? OK, some of you. 360 Glue? OK, a little more. So what we're looking at is take the rest of the team and bring you up to speed.

So that's kind of where we started. And then after we trained them, we want to coordinate-- get people to coordinate, get the teams to go back and forth and to work on it that way. And then, once we're done, we want to take our Glue model, put it to field, so that we can start doing punch lists from day one. So in construction, we always wait for the punch list until the last 30 days-- you know the 30-day close-out, et cetera, nightmare? So we want to start getting that done from the beginning.

So during our first coordination meeting, which was on December 16th, we set up all of the programs. We opened up Docs, we created the projects, we opened up Field, we created the project there. We created it in Glue.

At that point, we were able to add all of the subcontractors from the very beginning-- before we've had a chance to scrub through the models, and making sure that there are no information problems. You know, oh, I didn't get that update. Now you do.

So the first coordination meeting, we take stocks of the strengths and weaknesses. This is one case of taking a rookie team to build a professional stadium-- the clock was ticking. We determined the needs of the team from day one, and these images here, it was right before Christmas. And you can see a Texas winter there, it was like 50 degrees.

The rest of you guys that were under 6, 8, 10 feet of snow-- well, too bad.

All right, so our workflow went from Docs to Field to Glue. We would take the Revit model and then import it back to Glue, Field, and then just back and forth. And we were able to get the needs of our team, and you see Gabriel up there doesn't have an iPad. At the very start of this, two people on a team of 22 had iPads. So we were able to go in and simplify the model coordination, the clash detection, we were able to use the iPads for that.

And also, it allowed us access anywhere we happened to be. If you're in my class-- well, in Norm's class tomorrow-- he's talking about how the iPads are used, which iPad to select. And the whole presentation mostly is going to be from the iPad, so you can see that.

But the distributed project team-- of course, our BIM manager, our HVAC people, our designers, our structural engineer-- from the very beginning were all working together, were all going through spring training together, and were all working to mobilize and make sure that building is done. Again, we didn't have iPads, we didn't have a budget for BIM. And we're already into the project timeline.

Just some quick links that we used to set up-- the enterprise license allows us to go into Docs, otherwise it'd be BIM 360 Docs. I'm going to just walk through-- you create a project in BIM 360 Field. And you always are able to create the dollar amount-- and I think I put zero, I was told to put zero. So, OK. And no, we don't do stadiums for free.

We had a client recently, wanted us to do a high rise. And he said, oh, yeah, I think your company would be good to do this. But you got to reduce it by 20%. And it's like, OK, well 10% we could probably do-- 20%, we're paying the client to build his building. And you know, it's like, well, where's my bonus at the end of the year?

But what we-- I'm just going to flip through here-- once created, we get the projects done, we can add people, and-- let me see if I've got internet on this computer, if I do. Turn Doug Ferrar off. OK, seven-- sweet. I've learned something new-- I can switch the video between the two.

So I'm looking at BIM 360 Field. And we determined the knowledge of the team, and I'm working on just a couple here. But we want to determine the knowledge of the team. So what we've done is we've gone in and created a couple of checklists for the project, and you see, there's a few added here to my Cleburne project-- there's just a few. I took the this portion and reduced it down, otherwise, with the Autodesk Wi-Fi at 170 megabytes per second, we would be bored. I'm out of baseballs to throw around.

But what we did, we created a BIM pre-consruction checklist. I'm just going to go ahead and open that up. And you can see that, what is the goal for the virtual pre-construction?

As we're starting, we said, ask everyone-- what are we going to do with this? What is the future of this? How are we going to use it? Are we going to use it for fabrication? Or are we going to use it to have some pretty models for marketing?

How many marketing people do we have in here? OK, that's good, because usually there's one and he's like, well what does BIM mean? Oh, it's beautiful images for marketing.

[LAUGHTER]

We'd say, what's the goal? What are we going to use this for? In this case, we wanted to prefab all the steel, all the concrete, so that we can just put it together-- like a giant Lego set. That's the way our construction should be. A lot of times we get to building, and say, oh, it's going to take three months to lay all the Rebar out, it's going to take another three months to lay the concrete out.

And it's like, well, gee, if we prefab, we can have all the grade beams made up at a factory, have them shipped out, and that cuts the time down.

So anyway, but as we're looking, you just kind of see some of the things that we were asking-- the work scope. We were clear on the scope in our BIM execution plan, but we also made sure that everyone knew what scope they had. Again, just to keep people from working against themselves.

The game plan? Are you helping the project team with quantity take-off? Our estimators use-- I don't know what our estimators use, I forgot. But they take our model, they pull the quantities out. CostX-- they use CostX. And we ask-- we went through and we asked everything.

And we made sure that everyone who was a member of this team signed up, and you could see-- let me jump over here to admin-- you can see all the members of this team. And every one of them filled out a pre-con before we started.

Even the signage guys, because at Hunt AECOM, we've built nine of the last 12 stadiums with retractable roofs, and the signage always gets left out until the very end. So this one we were proactive, we looked at it, and we put it together.

Let me just go through. Now, once you create a checklist-- I'll back up a page here-- once you create a checklist, you can go in and export that out. Now, I thought for fun, we could go in and create our own checklist for the class.

Like I said, it's an interactive class, and this is where you're interactive. If you're asleep-- everyone awake? OK, I do want to say, smack your neighbor if they're asleep. Please don't smack your neighbor if they're asleep.

But we want to create a checklist. And you see we've got all these templates here that we can start from. Or we can create our own. Also, across the top here, we can create a QA/QC checklist, all of our punch lists, safety, commissioning, and then we'll look at the standard properties and custom properties as we go.

But I want to-- I'm just going to go to safety-- and you see the UAS flight record. Any drone pilots in here? You guys FAA certified? Do you have to create a safety checklist for the FAA?

AUDIENCE: No, not really.

PRESENTER: You will have to. I could give you this one, but-- OK, let's just start a new checklist. And I'm going to call it Class, and whatever company I'm with. And you see here's the list of our companies that worked on this project-- and I'm just going to leave it blank right now.

We've got we've got our tags that we can put in here, word tags, so when you set up an issue. I'm just going to say, footer text subliminally, and I'm going to add that checklist.

There we go. I was going to say, silence your phones, unless it's the guitar riff from "Stairway to Heaven," and then we'll take off our caps out of respect.

So there I created a new checklist. And I could start adding items to that checklist. It's blank, so whatever question I want to put there, in a pre-construction checklist, you might want to say, how many people know BIM? What's your BIM knowledge level? What is your level of competency? Do you need extra help? And you can put as many as you want.

In the drone, I think we've got like 200 things to checklist. And we've also put in there for the visual observer to check. One of the great questions that is in our checklists-- and all of our checklists-- is, are you impaired with alcohol?

And I guess since you're out in Vegas, have you been to one of the New Leaf clinics? Have you guys seen any of those? I think there's like 25. But coming from the airport Sunday, New Leaf clinic, what is that? Get your marijuana here. I though, OK.

I'm going to say, are you going to fill out survey? Hey, Larry-- five till 3:00, flag me. OK, so it says, are you going to fill out survey? And plus or minus, pass, fail, yes, no. But you can put your in there, and you can build the whole checklist that way.

OK, once you complete the checklist, you have a record that's going to stay in BIM 360 Field.

Now what we're wanting to do here, is we want to start educating our subcontractor base. So we found out their knowledge level, they don't know how to use BIM 360 Field or Glue, they don't even know how to open up Revit. Some may know how to open up Navisworks Freedom, we're not worried about that right now.

So what I'm going to do, is I'm going to go over to Revit, and as the GC, we open up the file on Revit, because we want to determine those types of situations. We want to look at the Revit. File we don't want our subcontractors modeling in Revit. If they're modeling in Revit, that's fine, but we don't want them to model in the design models.

So what we want to do is we want to share this model with Glue. We've already established that our Glue file, our Glue project, has been opened. And we want to take this and share it with Glue.

Now, the old way-- like two years ago, it's moving so fast now-- but the old way was to go and convert this file into a Navisworks file, then open up Navisworks, save it as an NWC, load it into Glue.

There is an add-in that Autodesk has out there-- it's a free add-in, let's go up there. And it is BIM 360 Glue. So when you open this up, that will allow you-- OK, connecting to Autodesk. And see if I can remember my password.

So does anyone work for a company that makes you change your password every 90 days, and you don't remember what it is?

Autodesk isn't like that, by the way. All right, so as it's signing into Glue, it comes up says, which project do you want to put this in? So we train our subs to put it in the proper project. We only give our subs access to the project they're on, otherwise we have a mess.

And some of the projects that I've got working on right here-- let's see if I can-- you guys are awfully quiet. Am I striking out, or what? There we go.

Pick the project I want to put the view in. Now, any 3D view you can Glue, you can take and attach it to Glue. Now what this does, it creates a link between the Revit file and the Glue file, so that if there's any updates in Glue, it will update the Revit file.

Navisworks, the same way-- you create that link, and if there's any updates there, it will translate back. And there we go-- come on internet. But you see, I can transfer any 2D view, as well. So every view that is in the Revit model, I can transfer over to Glue.

I'm not going to select all of them, or we'll be here till midnight. I'm just going to look down real quick, and say 3D views or somewhere-- sections, did I pass them? Building-- I'm just going to grab this one here. That's the current view. So I'm just going to go for current view.

And I'm going to hit Next, but I'm not going to Glue it. Because it's going to take a while. I've already pre-Glued it up here, so we don't have to sit here and watch the little wheel spin. And just go, well, you know, it's nice outside.

But it's just that simple. It will Glue over to 360 Glue. Now this model is the exact same one we were looking at. And again, I simplified the model for the class-- took all the site stuff out, took all the heavy stuff out. Because you never know when this is going to fail.

But this has been Glued, and there is the model that we were just looking at in Revit, but it comes across as a Navisworks file. The views-- we look at the shared views, and we say, maybe. So I don't have any shared views in this model yet-- I don't have any models. It's like, OK, great.

Now, I want to go over here to Navisworks, starts with a blank screen. And this is how you link the file from Glue to Navisworks. BIM 360, which is a standard add-on-- standard in Navisworks since 2016, before that you had to have the add-on. I'm just going to find my project.

And I have several views here. And I want to look at the dates, just because someone might have just uploaded one, and it's not linked to Navisworks yet, but these look the same. So this one's actually two minutes later. So I'm going to get that one, open it. That will open that file in Navisworks.

And my visualization department gets on me all the time because I don't load all the materials, and they're like, well, we can't do anything with that. Well, you know.

This is the same model that we're looking at, and I'm just going to zoom in here. And this is BB's favorite spot is the home plate-- whether I'm scoring or striking out, maybe. And I'm going to look at the crowd in the back. And up in BIM 360, there's a section there, says, Shared Views.

So I'm going to take this view and I'm going to share it. And I'm going to create a new shared view, call it Home Plate. You see it's right there, it's shared.

I'm just going to take save my Navisworks. So my Navisworks did save, and we'll go back to Glue. And then under Shared Views-- hopefully, now watch it not work. Let's try that save one more time. That's strike two, right? I get three.

All right, so one more time, Shared View, save it again. Up, up-- see the little exclamation point here? I do that so often, I forget-- that's saying that I need to sync up the Glue version to the Navisworks version. So I'm going to go ahead and sync that up. There we go.

So we did it so quick, you're thinking, well, all right. But that's the shared view to here.

One of the things that this program allows us to do-- who runs clash detections around here? How do you run them?

AUDIENCE: Work set to work set.

PRESENTER: Work set to work set? So Navisworks to Navisworks?

AUDIENCE: Yeah, from the Revit file.

PRESENTER: Is that pretty much from the Revit model? Pretty much the way it's done, right? OK, so what we discovered was is, if we take-- and I'm going to do a quick clash report here, find the clashes-- since I've only got one model in, I'm just going to go field level to-- see if there's anything in the dugout, just for jollies.

And it's not too bad. I've got 90 clashes here. All right, so I'm looking at the-- I'm going yeah, I've got these clashes. So let's just look at that one. That one looks pretty severe, and I've got all these windows open. But I'm going to send myself an email to me, since I'm the only one on this project right now. And I'm going to say, check this out.

And I'll send it. Notification was sent. So somewhere, I'm getting email. My IT department can't fix the email on my iPhone, so it's in the bag here. It's great because I don't get messed with from the office, I go back to the room and it's like, oh, yeah, I didn't see your email until-- your office has already called, sorry.

So all right, let's jump back to Revit. Let's refresh my Revit. So where is my Refresh button? Somewhere. Anyone see the Refresh button?

Let's see if it went that way. There we go. I was in AU classes model, right? So I view that, there is that clash in Revit now that I found in Glue. So I want to look at that one, and I want to view that selected clash. And there is that selected clash from Glue.

With BIM 360 Glue, I can link back to Revit. Now I sent that email out to the design team, they know we've got a problem, they can correct it. So we're all linked together, we're talking to each other.

I'm skipping over this, because you always put your slides in case your live demo fails-- I've had a couple fail on me. But AU's gotten so much better. I remember 10 years ago, I guess, I was giving a class, and the internet didn't work, and I looked really silly. The classes were 700 then, instead of 100. So it's nice.

Now what we want to do, to keep going-- I'm doing fine, Larry, give me another 10 minutes. Anyone getting tired yet? You've been sitting a long time? I Just hang on for just a second.

So the last-- we talked about educating the subcontractor base. We looked at that. The coordination of Revit Glue models is very easy. If you get the coordinates from the design team and put it in the Revit model. When you save that to Glue, those coordinates will carry over. Everything will line up according to those design coordinates.

If it doesn't, when you move a model in Glue-- come back over here, shove all these windows down-- if you move something in Glue, that coordinate will stay forever. So if you line the coordinates up correctly in Glue from the design model, you don't have to change them again.

Unlike Navisworks, where, if you load a new file in, and it's set to zero-- so why do structural guys always give 100 feet? Oh, we're going to start at 100 feet. So that's just the side trail.

So anyway, so setting those coordinates are always going to be that simple. Now, in Glue-- let's go ahead and we want to know how to link. So we've taught the subcontractors how to load up to Glue. We've taught them how to work in Glue, by using Revit. You can also link to AutoCAD. There is a link to Bentley, but it doesn't work all the time, so if you're using Bentley-- I know it's an Autodesk conference, so sacrilege Bentley.

But there is that link. And so from AutoCAD, Revit, it's the same link to the Glue model and to Field. So what we want to do, as our last step here, we want to take-- oh, I get plenty of time-- we want to take this model and link it to Field. So just on your tabs here, you've got the Model tab, and you see, if I had multiple models in here, in this one, I could link individual models to Field.

See, I'm only working on the structure at this time, I'm just going to link the structural model over. See, all these people leaving (WHISPERS) are missing a big one.

So OK, so you pull the fly out and you share with Field. And it'll say, share this model with Field. OK, yeah, it's been shared with Field. I'm going back to field right there.

Now, this part of it, you have to have admin rights in order to do that, to link it. Talk to your IT people and tell them you need admin rights, project admin, account admin, and if they give you guff, you say, well, I need it to do my job, and you say, you guys are standing in my way and it is bonus season, so blame your IT department.

Just kidding.

When I come in, you see that the version seven, which was the one I was just working on, is coming in, and it will coordinate-- actually, that's two months ago.

I'm just going to start deleting stuff. There we go. And then, oh, I'm looking at the wrong project. I could do that all day, and it's like, where did my stuff go? There we go. Ta-dah.

So four days ago, I linked this model and put it in. I don't know if the Autodesk internet is working as fast as it should. But we'll just see as it's loading here. And while that's loading, model coordinates, we'll jump back to the model coordinates. Get those model coordinates from the design model. Focus on consistent naming, we all know this.

So the biggest fails in projects are, we name things every way possible. Consistent naming-- this was project 10,000, so 10,000 underscore architectural files, underscore level one. And as a point of preference, I never put the date on my naming conventions, because the dates always change. And then you have to recreate everything.

So it's taking a little longer than I thought, but-- anybody tired? Where's my baseball fans at?

AUDIENCE: Seventh inning?

PRESENTER: Yeah, let's to the seventh inning stretch. Stand up, shake the person's hand next to you, introduce yourself.

[MUSIC PLAYING, "TAKE ME OUT TO THE BALLGAME"]

And then we'll sing the chorus, all right?

- (SINGING) Katie Casey was baseball mad, had the fever and had it bad. Just to root for the hometown crew, every sou, Katie blew.

On a Saturday, her young beau called to see if she'd like to go--

PRESENTER: There we go.

- (SINGING) But Miss Kate said, no, but I'll tell you what you can do.

PRESENTER: So there's the trivia question. Do not Google it, if you don't know it.

- (SINGING) Take me out to the crowd. Buy me some peanuts and crackerjacks, I don't care if I never get back. Let me root, root, root for the home team, if they don't win it's a shame--

PRESENTER: Number two, OK. Did you say it before he did it? So you said number two, right? She beat you.

All right, oh, you said it? Collusion, here. OK, here, you guys can split the Big League Chew bubble gum, there.

The answer to that trivia question, who invented baseball? Is Abner Doubleday. The girl that works for me, she's studying her American citizenship test, and I was looking through it, and I said, what? It doesn't have who invented baseball on there?

Yeah, that's kind of-- all right.

- (SINGING) Let me root, root, root for the home team--

PRESENTER: This, like I said, this was the 1903 version of the recording I found online. So on Edison Records. And at my house. I've got a 1919 Brunswick, that's an old crank, and so I was able to put that up to a microphone and record it.

All right, we looked, just real quick, we looked at how to Glue the field, and how to Glue to field. I'm going to switch back to this, because that's what I was kind of waiting for. There we go.

And you see all the models popped up from all-- well, that's the last project I worked on. So I'm going to say if there's any for here. And there's that model that we just loaded up there.

As we Glue that over, it says the model's processing. And it may take five minutes, it may take 50 minutes, it just depends. Now this model that is Gluing right now, and I don't have an iPad hooked up, but it is going to the iPad, as well. So when you sync up the iPad, you'll have this model, with all of the views, with all the information from that model.

Like I said, it could take now, could take forever. The seven take, or eight take-- there we go. These things are complicated. All right, so that's going, we'll just jump back over here. And I'll walk through this. Just make sure, fly out window, join to Field. Then you've got all your various things.

Again, make sure to put that model, you go to the Equipment tab, you put that model in. And then make sure that you're signed on as an admin.

So we looked at the team. We determined the needs of our team, through our pre-construction checklist. And if anyone needs that, send me a note and I can give you a copy of that. And so you can have something to start off with. We educated our subcontractors-- so now we can look at this and go over it a little bit.

If you downloaded the notes, I've got a pretty detailed in the notes, the handout. So you can look at that. Coordinate the process-- is that you?

AUDIENCE: That's your 10 minute warning.

PRESENTER: Oh, is it? OK. And then we looked at how to Glue from Glue to Field. So all four of those programs are used-- Revit, Glue, Field, Navisworks. They're all linked together. And again, I could have done it in AutoCAD, but yeah, for time.

All right, and of course, the video is publicdomain.com, the music was publicdomain.com, and my wife took all the pictures, all right, any questions? Yes, sir?

AUDIENCE: [INAUDIBLE] but I was just trying to figure out [INAUDIBLE]. What exactly was the point of [INAUDIBLE]?

PRESENTER: OK, a lot of our subcontractors don't have a Revit license. They will have an AutoCAD, and so it's the same process going through AutoCAD. But a lot of people aren't willing to spend the money to upgrade the software, so they'll have Navisworks Freedom that they can look at to do that, and make notes and changes on.

AUDIENCE: The free-- it's a free download.

PRESENTER: Right, but they can create views in Navisworks Freedom. So if they're building there, then it's going to be linked back to the rest of the team, so that as I send out an email, people know that there's a change. Does that answer your question?

Did everybody hear his question? I like the acoustics in this room, it's great. OK, anybody else? That's a good question.

I have a bat to give you, come by the base and I'll give you one. Anybody else?

AUDIENCE: So when you said you went-- it was all papers. So your submittals-- it's not my expertise, but so you're submittals went out, like all your [INAUDIBLE], did you send that to fabricators? Or how did they access that? So to build the trusses and whatever else you got there?

PRESENTER: Yeah, our fabricators were included in this process, as well. And so when the submittals came in, they were able to see the submittals and start the fabrication process. And so when we did the final model, it was the 3D shop drawings that we put that together with. Yes, sir?

AUDIENCE: So if you got the [INAUDIBLE], like it is in [INAUDIBLE]. And as it approaches [INAUDIBLE], do you find people getting more excited about [INAUDIBLE]? More interested, or did you have to [INAUDIBLE]?

PRESENTER: Well, OK, at the very beginning, we had that pushback. And people were all, we're not going to do this. Well, you signed a contract, so you're going to do it.

As we enforced the whole process, what I noticed was the subcontractors were calling each other to resolve issues before our coordination meetings. Sometimes that can be a pain, because I'm a stickler to that. But what I noticed, they were talking to each other, they were resolving their issues beforehand. And then at the end of the process, they were working together.

And a lot of the same contractors were-- we've gotten hired on our Amarillo stadium that we're building. So we're able to help them. So yeah?

AUDIENCE: [INAUDIBLE]?

PRESENTER: In the beginning, we had a couple thousand. But they were information RFIs, they weren't, well, this window's the wrong size. And so we were able to reduce those, answer those, and reduce the physical RFIs as far as parts and pieces down. Probably 35% of a comparable stadium that we did a couple years ago. Yeah?

AUDIENCE: How often did you guys [INAUDIBLE]?

PRESENTER: Twice a week. Because it's so fast tracked, we wanted to make sure everything was going on top. Yeah, Larry?

AUDIENCE: Do you think those subs that were coordinating with each other before they got to the coordination meeting, and solving those problems, do you think it's because they were looking at 3D models and catching things that they would normally not catch on paper?

PRESENTER: Yes. Larry's question was, do you think the subs war catching problems and things on a 3D model that they wouldn't catch on paper? And yes. A 3D model is always better to visualize than a 2D representation. Yes, sir?

AUDIENCE: And just, I have been part of this workflow before, where [INAUDIBLE], so typically we try to resolve any trade to trade conflicts leading up to a design coordination meeting, that way we can flesh out any design issues. That way we're not talking about [? profit ?] and resolving our own things away from the main coordination. [? That way when the ?] design team is injected into the coordination, we can either get verbals and proceed with coordination, or they could make adjustments [INAUDIBLE], and then we can proceed.

As we know, [INAUDIBLE] coordination's a major milestone on a [INAUDIBLE] schedule, so anything [INAUDIBLE] downstream. So [INAUDIBLE].

They [INAUDIBLE] with manpower ready to go, but you can't sign off, [INAUDIBLE].

PRESENTER: Yeah, we did a lot of verbal coordination.

AUDIENCE: It's difficult to track those verbals, because the verbal isn't set in stone.

PRESENTER: That's kind of one of the lessons learned is, when you say verbal, follow it up with an email, put it in the system. So, all right. Anybody else? Going once, going twice, OK.

Then I think we are done.
