All Things BIM

AGC BIMForum and More

2012-05-15T15:32:00.001-04:00

I recently attended my seventh BIMForum event held at the Grand Hyatt in San Antonio, Texas. The theme for this event was “VDC (virtual design & construction) Deliverables.” I’ll comment more on the theme later. First, allow me to describe this conference. The BIMForum is a group that is organized by the Associated General Contractors of America (AGC) and whose mission is to “facilitate and accelerate the adoption of building information modeling in the AEC industry”…to “lead by example and synchronize with counterparts in all sectors of the industry to jointly develop best practice for virtual design and construction.” Recently, the AIA (American Institute of Architects) signed on to be an integral contributor to the BIMForum as well (talk about reaching across the aisle!!). You can learn all about the group and sign-up at bimforum.org. As a paid member, you can access recordings of past events.

Over the past few years, the AGC originally hosted 4 BIMForum events per year, but they reduced that to 3 in 2011 and now are hosting 2 annual conferences. Each event consists of a day and a half of presentations around a common theme. Presenters must be experienced in using and/or delivering BIM-based services and the longest presentations are 1 hour. Attendance has been quite solid at around 400 which makes for a lively audience, but not overwhelming for good networking. There are no concurrent sessions, which makes every BIMForum conference one of the more easy-to-attend events in my experience.

Each conference is established around a specific theme that seems to always be timely and relevant. The Fall 2011 event theme was “Return on Innovation Investment (ROI²)” which prompted the presenters to focus on the costs and benefits of using BIM-based processes. There were quite a few extremely valuable sessions describing compelling cost to benefit ratios, including a presentation from Dan Russell of Sundt Construction who illustrated that the cost to ‘do BIM’ was equivalent to the cost required to keep a building site broom-swept during construction!

Who should attend a BIMForum event? These events are more inspirational and informational in nature than events such as Autodesk University or Revit Technology Conference. If you are already knee deep in BIM implementation and consider yourself an expert user, these events may not be for you. If you are a decision-maker for your firm and you want to keep up with the competition or get started with realistic BIM implementation, the BIMForum offers the perfect event to showcase real people and real projects getting real results.

The Spring 2012 BIMForum theme was “VDC Deliverables” in which the presentations were to focus on “VDC deliverables that are specific results of digital processes that improved results…ways that the deliverables were used to solve specific problems.” I admit that I may have slightly misinterpreted the theme as one that would focus on using VDC processes to improve deliverables; instead of the deliverables of the VDC process. As such, I was somewhat disappointed that more presentations didn’t specifically address the transition of design modeling to construction modeling. That said, it was still an inspiring event and I look forward to attending more BIMForums in the future.

Look for me at two upcoming industry events. At the AIA National Convention in Washington, DC, I will be presenting as part of an expert panel on the topic of “Information and Energy Modeling for Code Compliance: A Guide to Methods and Means.” That presentation starts at 4:00 pm on Friday. I am also presenting a topic I called “Building Smarter Models” at the Revit Technology Conference in Stone Mountain, Georgia. That class is also a Friday-at-4 fire-the-crowd-up-before-cocktails time slot.

Hope to see you at these and future events! I will vow to protect as many fluffy kittens as possible. Thanks to Amy for the cute stationery pictured above. Speaking of which…those in attendance might have noticed my fluffy kitten meme shirt (“Revenge of the Fluffy Kitten: The Sequel”). If you’re interested in buying fluffy kitten merchandise, let me know and I’ll consider setting up an online shop! Thanks Liz for the gift shop find (below)!

New Features of Navisworks 2013

2012-04-25T16:59:00.001-04:00

Whilst David Light has cornered the market on ‘what’s new in Revit,’ I figured I’d take a moment to summarize some of the new features in Navisworks – one of my other favorite applications. There are quite a few enhancements for handling Revit models this year and I’m pretty excited about the changes.

Open RVT Files Directly

Yes, you heard that correctly. You can now merge RVT files directly from Navisworks without pre-exporting an NWC file from within Revit. This will probably be a true delight for builders who may no longer need an installation of Revit just to get the model data into Navisworks. Model components from a Revit model are now organized in the Selection Tree according to category, family, type, and instance.

CAVEAT: This functionality will open the RVT file and will look for a 3D view for which the name contains “Navis.” If one is found, it will load the data that is visible in that view.

Grid and Level Support

In the 3D coordination process, it’s usually quite difficult to determine your location when you are automatically zoomed to a clash condition. David Kingham first posted a workaround to create 3D grid objects, but now it has made its way into the core software. (As an aside, please visit David’s new professional photography website…very impressive work!)

Lee Mullin wrote a great summary of this new feature over on the Beyond Design blog, including a video.

Clash Detection Enhancements

One of the first things you’ll notice in Navisworks 2013 is that a new interface for Clash Detective has been created. This new UI makes it easier to discover and organize clashes. Because the grids and levels are now included from Revit, you can group and filter clashes according to grid and/or level location. You’ll need to right-click on the row headers and select Choose Columns as shown below. Note that these options won’t be available for older projects without the supporting information.

Timeliner Enhancements

Money…that’s what I want… You can now add cost data to your Timeliner simulation to better understand accumulated costs anywhere in the construction process. Objects and selection sets can be dragged and dropped into Timeliner to easily create associations between the model and schedule tasks. Timeliner simulations can be exported to ProjectXML to support interoperability with Primavera and Microsoft Project.

Improved File Interoperability

Navisworks 2013 now supports CATIA and Solidworks files from Dassault Sytemes, ArchiCAD 14 and 15 files, Siemens NX PLM software, and point clouds from Faro 4.8. Timeliner can also now connect to Oracle Primavera P6 v8, Asta Powerproject 12 and Microsoft Project 2010.

As a little bonus footage, check out this demo video from SMART Technologies about how you can now use a SMART board monitor overlay with Navisworks for team model review:

IFC Export from Revit: Reply

2012-04-09T10:31:00.001-04:00

I’ve been monitoring the discussions in the Industry Foundation Classes (IFC) group on LinkedIn for some time now and recently saw a post criticizing IFC export from Revit 2012. I saw a few discrepancies in the methods described in the blog post, so I decided to run through the same tests myself.

To ensure I had the same setup as the original post author, I created a new project in Revit Architecture 2012 using the default template. I created three phases: Past, Present, and Future. Three desks and three walls were modeled and I added a floor slab under each wall/desk just for context. The first (left) wall/desk/floor is assigned to the Past phase and the wall + desk were demolished in the Present phase. The middle wall/desk/floor are on the Present phase and the right wall/desk/floor are on the Future phase. In the image below, the Phase Filter is set to None to show all three sets of objects.

(Click on any of the images in this post to see the enlarged version)

I was using Tekla BIMSight version 1.5 for all IFC viewing; loading all IFC exports into one project and using the visibility setting for each model to display the results (shown highlighted in each image). For consistency, all IFC exports from Revit were set to IFC 2x3 and Current View Only:

One of the first things I noticed in the original blog post was that the author was utilizing Temporary Hide-Isolate to change the visibility of some elements. In training and use of Revit through the years, I’ve always understood that this tool only made temporary changes to visibility (thus the name); therefore, it should not affect printing or exporting. I proceeded to test this by hiding two of the desks in a view:

When you attempt to export with Temporary Hide-Isolate activated, you get this warning:

I chose to “Leave the Temporary Hide/Isolate mode on and export” and got the same result as the original blog author. Note the warning, “Affected elements may be exported with unexpected visual characteristics.” The desks that were temporarily hidden did not export. My suggestion for users…don’t attempt to use Temporary Hide/Isolate for exporting or printing.

The next test was to test the Phase Filters. I set a 3D view to Phase: Future and Phase Filter: Show New:

In the resulting IFC export, you can see that the phase filter is not recognized even though we are supposedly exporting “Current View Only.” As you can see in the image below, even though the phase filter of the view is being ignored, the desk and wall that were demolished are not shown:

The next test was to examine the effect of hiding a category of objects. In this test, I created a 3D view with the Phase Filter set to None and the Walls category was turned off in Visibility/Graphic Overrides for the view:

This process seemed to work, but it still ignored the Phase Filter of the view:

I attempted one more experiment using the Present phase. Revit should not export anything that is in a ‘future’ phase, so we shouldn’t have a problem here:

Unfortunately, you can see below that even though the Revit view displayed only the Present phase – ALL phases were exported to IFC – even the Future phase:

Conclusion

To summarize my testing of IFC export from Revit Architecture 2012, here are my findings:

BAD: Don’t use Temporary Hide/Isolate to export or print
BAD: IFC export ignores the Phase Filter parameter of a view
GOOD/BAD: IFC honors the Phase Demolished parameter of model objects*

Except the fact that if you’re exporting the Past phase, the demolished elements appear in the Revit view, but are still omitted from the IFC

GOOD: IFC honors Visibility/Graphic Overrides of object categories

At HOK, we have experienced additional IFC export problems with curtain walls that have edited profiles and stacked walls. I’ll conduct some additional tests as well as conduct these same tests with Revit 2013 in a future post.

If you’d like to experiment with the files I used for this test, you can download them here.

Effective User Groups, Part 3

2012-04-06T15:48:00.001-04:00

To all my readers, I can’t believe I drafted the final post in this series back in January and completely forgot to upload it to the blog! If you were anxiously awaiting this conclusion, I’m sorry for the delay. As the kids say…”My bad!”

This is the third and final post in my series about implementing effective user groups. In Part 1, I discussed getting a group started, organizing topics and speakers, and meeting locations. Part 2 included tips about meeting locations and group websites. To conclude the series, I’ll share some tidbits about hardware and sponsors.

Hardware

First, let’s talk about a simple topic that rounds out our previous chat on websites and general technology. While it’s safe to say that a halfway decent laptop is a minimum requirement for a successful meeting, there are a few other items to note. To broadcast our meetings via the web, I use a USB Desktop Microphone from Logitech. It does a superb job at picking up sound in the general vicinity of the presenter(s). These days, I’ve also found that a webcam of reasonable quality (such as the Logitech HD Pro C910) will usually deliver good audio. In the near future, I expect GotoWebinar will include the ability to broadcast video as they do in GotoMeeting.

Here’s a checklist you might use that is loosely related to hardware, but includes some other important issues:

Whose laptop will be used?
Make sure presentations are copied to a USB drive.
Always bring spare cables (audio/visual/network).
Laptop power supply?
Get written approval (at least via email) from your presenter for recording.
Merge the intro and formal presentation slides to avoid awkward transitions.
In software demonstrations, make sure all necessary files and applications are opened BEFORE starting the presentation.
If you’re broadcasting via the web, be sure to repeat any questions asked by your live audience. Hearing only the answers can get a bit confusing to your web audience.

Group Procedures

If you’re lucky enough to have a good group of volunteers help you organize and operate your events, it can get pretty difficult to maintain control over all the moving parts of a modern, high-tech group. We have found great success in writing a sort of ‘user manual’ for our group’s operations. This allows any one of our group leaders to schedule, configure, and run an event without missing any of the steps related to the guest speakers, the facility, and the broadcasting technology. I’ve created a generic version of our document as a template for you to use in your groups. Feel free to download the document via the link below.

RTC US Mystery Topic

2012-04-05T10:58:00.001-04:00

As you can see from the new badge on my blog page, I’ll be speaking at the Revit Technology Conference in Atlanta, GA this June. This will be my first time attending and speaking at an RTC event which is managed by some of my good buddies Wes, Phil, Steve, and Jim (among others). I was supposed to give a presentation on effective coordination when the conference debuted in the US in California, but a last-minute client scheduling conflict prevented me from attending. If you were there, hopefully you enjoyed Amy Patel’s delivery of my topic.

If you haven’t registered yet, do so soon because word has it, they are seeing record high numbers of registrants and space might run out. I recently completed my registration and the classes all look quite interesting.

The class title I submitted was intended to be somewhat nebulous because I wanted to step outside the ‘Revit tutorial’ box and talk about important topics related to overall success with BIM implementation. “Building Smarter Models” will cover a few of the areas of research and development in which I’ve been involved over the past few years since I last presented at an event like Autodesk University (remember “You Can’t Do That With Revit?”).

I hope to leave a decent amount of time open for Q&A, but the session specifics will touch on use of IFC (understanding IDM and MVD), development of NBIMS, analysis of and addressing client BIM requirements, and a review of HOK’s “BIM Certified” program. Please comment on this post if you have any suggestions to enhance my topics before I complete the presentation (early June).

Topic: Building Smarter Models

As the building industry starts shifting away from document-based deliverables towards models, it is important for the authors (architects, engineers, and builders) to understand the requirements for quality content development. In this session, you will learn about the latest developments in open standards, how to address client BIM requirements, and methods for avoiding “BIM wash.”

Key Learning Objectives:

Develop an understanding of industry open BIM standards.
Learn how to develop high-quality models suitable for sharing with other project stakeholders.
Establish a measurable approach to implementing BIM workflows for your company or project.

New Features of Revit 2013

2012-03-28T11:27:00.001-04:00

The news is now starting to flood the blogosphere…Revit 2013 will soon arrive! As usual, Mastering Revit contributing author, David Light, has provided an in-depth review of the new features. Please hop on over to his blog and read all about it…

Moving Forward with LOD

2012-03-01T10:09:00.001-05:00

I first wrote about LOD (I’ll break down the acronym later) and the AIA E202 BIM Protocol Exhibit in a post from December 2008, but the topic is such an important part of doing BIM right that I wanted to bring it back for further definition. Here we are three years later and I am reflecting on the last statement of that post…

“[The BIM Protocol Exhibit]…has not yet become a formal addendum to any of our project contracts. That will likely change very soon.”

Since early in 2011, I have been participating in a work group that was spawned from the AIA and the AGC BIMForum to further expand upon the LOD definitions. That is to say, if you are a designer, engineer, or builder and you are asked to provide model elements at LOD### – do you know what you are required to provide? The group will be presenting a progress update at the upcoming BIMForum event in San Antonio, Texas, but for now, allow me to share some insight I have gained while involved with the group.

What is “LOD?”

First, let’s get our terminology straight. According to the AIA E202 document, LOD is defined as “level of development.” It does NOT mean “level of detail;” however, this is an important concept. Unfortunately, the choice of words makes for increased confusion over the acronym, but there definitely is a difference.

Level of detail is the amount of information and geometry provided by the content author or other project participant. There can always be a higher level of detail in a project model than what is realistic to be used by others in a downstream workflow. Level of development is the maximum amount of information and geometry that is authorized for use by others.

Expressed in different terms: DETAIL = INPUT and DEVELOPMENT = RELIABILITY

No Such Thing as an “LOD### Model”

I mentioned this in a recent post about the ‘fluffy kittens,’ but allow me to reiterate the point that LOD is based on assemblies – NOT entire models. In my opinion, the easiest way to understand this is to separate the milestone deliverables from your thinking about LOD’s. In other words, don’t think that schematic design = LOD100; design development = LOD200; and so on.

At any given project milestone, you will likely have a combination of LOD’s. For example, at the end of construction documents, the interior walls and doors might be at LOD300, furniture is at LOD200, and information about electrical fixtures is only supplied as an allowance per square foot; thus LOD100.

Let me explain this a little further with an example many firms are using (including some folks at HOK). Below is a screenshot from an LOD modeling guide offered by one of the participants in the LOD work group. I won’t use the person’s name or the firm name, but I certainly do not mean any disrespect by using this example (many others make the same assumption).

In this image, a progression in LOD is assumed to be aligned with the development of the project design – probably from SD to DD to CD. However, if you look closely at the difference between the 200 and 300 plans, elements like the plumbing fixtures seem to be the same model object. How can that be if the deliverables are at two different LOD’s? What if instead we label the plans as “SD Floor Plan,” “DD Floor Plan,” and “CD Floor Plan?” In the example above, you might know exactly what manufacturer and model number the plumbing fixtures will be (‘buy it’), so that assembly will be listed at LOD300 in the DD and CD deliverables.

In contemplating the LOD concept as it relates to any assembly or component in a project model, I developed the following (although I’m still working on a better explanation for 100):

LOD100 = Interpolated calculations (estimates)
LOD200 = Specify it
LOD300 = Buy it
LOD400 = Build or install it
LOD500 = Operate or maintain it

The above list simplifies the concept of authorized uses. Essentially, what you should be able to do with an object given a certain amount of input information.

Does LOD Imply Time?

Another misconception about LOD is that it implies an ‘in progress’ state of content. For example, you might think that LOD200 means that you are placing manufacturer-specific content in your model, but you are still in an early phase of design such that quantities and locations are not finalized. In this case, the correct LOD assignment would be LOD300 with the understanding that at design milestones quantities and locations will be in flux.

Here’s another twist, if you are working on a project that will be competitively bid – essentially, design-bid-build – what LOD would you use for final construction documents? If you think about it, specifications for bid projects usually allow for (or require) a list of alternate products (Wicks Law, New York state). As such, even if you are using a model component provided by a specific manufacturer, the level of development (reliability) can only be at a generic level – LOD200. This may seem counter-intuitive, but a full understanding of these levels is going to form the foundation of ‘good input’ for the industry to start realizing improved interoperability.

I invite you to read more about LOD at the Vico Software website, BIModal Evolution blog, Revit Sticky Notes, Revit OpEd, The BIM Manager, and Q5 (Tocci). There are also some good discussions happening in the BIM Experts group on LinkedIn.

New Version of Tekla BIMsight

2012-01-31T09:47:00.001-05:00

If you haven’t already heard of Tekla BIMsight, you should take a look. I first saw it at one of the AGC BIMForum conferences last year. It is a free – yes, free – tool for 3D coordination using aggregated design or fabrication models (notice, no kittens harmed here). BIMsight now offers support for tablets including multi-touch hand gestures as well as stylus use. And yet again, another tool that uses – guess what? – IFC format for input.

I’ll be running some informal tests of this tool in the near future. In the meantime, feel free to share your experiences in the comments below.

Effective User Groups, Part 2

2012-01-27T01:16:00.001-05:00

Following up on Part 1 of my tips for organizing and maintaining effective user groups, this post will cover the physical and virtual spaces that support great interaction.

Meeting Locations

Where you host your meetings is probably the biggest variable in the equation for an effective user group. There’s no perfect answer because you must find the best balance of function, space, and cost that meets your needs. I’ll offer my own experiences for your evaluation.

Offices

Probably the most common place to start a user group is at the leader’s office. If you have a large enough conference room or even a lobby space with plenty of stacking/folding chairs, this might be all you need. Sometimes it’s fun to rotate locations of a user group meeting to various participating companies. The main drawback is the number of people you can pack into a space. Meetings can get disrupted when attendees are standing or sitting on the floor (yes, I’ve had that experience!)

Issues: Building security, space set up & clean up, limited number of attendees

Hotels

The DC Revit Users Group meets at a beautiful space atop the Key Bridge Marriott in Arlington. I’ve done some research in the past into meeting spaces in New York City and the cost may be $1,000 – $2,000 per event.

Issues: Cost

Showrooms

These kinds of spaces are likely only available in major metropolitan centers, but they are an interesting option. Product manufacturers like Steelcase may have showrooms in your region that can be utilized for group functions. In NYC, I’ve attended events at Steelcase, The Gunlocke Company, Haefele, and the McGraw Hill Auditorium. I’ve never organized a meeting at a showroom, so I can’t speak to the costs involved.

Issues: Cost?

Restaurants

Why not mix learning and networking with some food? I’ve attended a few user group meetings held at restaurants over the years. One of the early NYC Revit User Group meetings was held at a bar which was actually an old bank. Our ‘private meeting room’ was actually the old vault and I recall giving a presentation where the ‘screen’ was actually a backdrop of safe deposit boxes! The Ontario RUG used to meet at a restaurant called Alice Fazooli’s. This was fun because they had a large dedicated space and the food was great.

Issues: Cost, A/V equipment

Academic Institutions

Our group was really fortunate to connect with Pratt Institute and use their lecture space on a monthly basis. For two years, we were able to utilize this space without cost because they enjoy the exposure for Pratt’s continuing & professional studies programs in the building. Recently we were asked to provide insurance coverage for our meetings and yet again, an interested company came to the rescue to provide this contribution as a group sponsor. More on this to come in Part 3…

Personally, I think an academic location is the best option because it seems that it is the most mutually beneficial solution. You can bring potential students in and they can provide a space well-suited to learning events. So reach out to your local university or technical college and see if they are willing to share some space.

Group Websites

Now that we’ve covered the physical space, let’s talk about virtual space. As I mentioned in Part 1, there are so many free social tools available on the web today that can support groups. When we got the NYC RUG started in 2006, Google Groups was a pretty good option. This free service is still around, but its functionality is somewhat limited. You can create custom pages, upload files and manage members – but that’s about it. I’d keep an eye on Google+ and see how it evolves.

In addition to an Internet home for your group, you should also think about how you want to handle events. In the past I used Evite.com to manage events while we were on Google Groups. It’s a free service and does a nice job handling RSVP’s and automated reminders; however, it wasn’t integrated with the group website, so I had to manage two member databases.

Facebook seems to have highly functional group tools where you can create and manage events, have discussions, post links, photos and videos. It’s all free, but you have to be a Facebook user to join a group. Some people like to keep their personal interactions on Facebook, so they may not want to mix business-related stuff there. Also, some offices may even block access to social sites like Facebook. LinkedIn has groups as well, but I haven’t found them as easy to use as FB.

The NYC Revit Users Group uses a site called Meetup.com. It’s a paid service ($45 every three months), but our members seem to really appreciate the functionality. It has discussion boards, file/photo uploads, topic suggestions, and it’s event management is great. Automated email reminders, dues collection (if applicable), name tags, sign-in sheet, and more.

I’ve only discussed a few web-based group platforms here, but there are so many more out there. Do some homework, look at other group sites and pick one that suits your taste such as Ning.

Effective User Groups, Part 1

2012-01-19T23:48:00.001-05:00

I’ve been thinking about sharing my user group experiences for some time now and an email came in asking me about just such information. (How do you approach businesses or individuals to attend and then speak at the meetings? How do secure sponsors for venues and food? How do you deal with topics specifically geared towards a particular discipline without losing the rest of your members?…) Needless to say, I am taking the initiative to write about the evolution of the New York City Revit Users Group.

In a series of posts, I’ll discuss the following topics:

Getting a group started
Organizing topics and speakers
Meeting locations
Group websites
Sponsors
A/V technology

I hope you will find my opinions interesting and I welcome comments about your experiences.

Getting a Group Started

There’s quite a bit of a story leading up to April 2006 that I now realize will have to be yet another series of posts on my journey with BIM. That said, I was 2 years into implementing Revit on World Trade Center Tower One at SOM and each of the New York area Autodesk resellers were starting to ramp up their own Revit user groups. As I recall, there were at least two – maybe three – separate groups and they all wanted me to speak at their events at one time or another. I thought, "there has to be a better way.”

Lesson #1: By the people, for the people

Users don’t need to sell anything. There…I said it. I have the utmost respect for the VAR’s (value-added resellers) and trainers with whom I’ve collaborated in my career, but (in my opinion) they don’t have that grassroots, real world, in the trenches, battle-scarred approach to the tools. Whether a VAR has an agenda or not, I frequently get that feeling when I attend a VAR-organized user group. We’ll talk more about sponsorship later…

The first step in creating a successful user group is finding some local people in your industry who share the same passion. Look at your current or most recent project team, consultants, contractors…did you make some new friends as you worked through the last all-night deadline? Get together for lunch a few times and you might have the seedlings for a user group!

Back in 2006, we didn’t have Twitter or Facebook, so getting the word out about new user groups was either by word of mouth or mass e-mailings (but you had to know your recipients first!). And websites were pretty expensive back then…if GoDaddy.com was around, you sure couldn’t buy a site for $9.99 and be up and running in a matter of minutes.

Today, you can create a group presence for free on Facebook with just about everything you’d need to get a group going. More on technology in a forthcoming post…

Lesson #2: Maintain regular meetings

Research has shown that the leading cause of user group death is apathy. OK, that’s my own observation, but I’ve seen it happen. Even if you just get together and have a roundtable discussion about BIM standards, it’s still a meeting and your attendees will come to expect the next regularly scheduled meeting.

Organizing Speakers and Topics

So, what’s the magic formula for finding interesting speakers and topics? Sorry, there isn’t one. In the early days, we did two things: spoke about our own experiences; and had VAR trainers give how-to lectures. The best advice I can give to new organizers is to network, network, and then network some more. I’ve met so many people at events like Autodesk University and those connections inevitably lead to memorable guest appearances for our group.

Lesson #3: Get help

We have been conducting regular monthly meetings for almost 5 years and with over 770 registered members, we only recently have achieved 10 volunteers on our advisory board. The overwhelming majority of user group attendees just want to receive content – not participate in creating the content. The best thing our group did was to assign vice presidents (those who were the most active and available to co-organize the meetings), and create an advisory board of members who just wanted to help contribute topic ideas and perhaps suggest some contact connections for guest speakers. The burden shouldn’t rest squarely on one person.

Lesson #4: Lock in dates for guests early

When you are speaking to potential guest speakers, try to get them to commit to a date far in advance. They may not know what their schedules look like two months or more ahead, but they will know when they have agreed to present at your group.

Stay tuned for Part 2 of this series, coming soon…

Event: BIM in Modular and Prefab Construction

2012-01-18T13:09:00.001-05:00

As the president of the New York City Revit Users Group (nyc-rug.com), I organize monthly meetings around various BIM-related topics. The January 2012 meeting featured guest speaker Ian Atkins who shared some of his real-world experience in applying BIM to modular and prefabricated construction.
UPDATE:
Unfortunately, Kullman has requested we remove the recording of Ian's presentation and we have complied. Please stay connected with the NYC RUG for upcoming meetings and feel free to browse previously recorded meetings at http://vimeo.com/groups/revitusers.

Protect the fluffy kittens

2011-12-12T02:47:00.001-05:00

Have you ever been frustrated when people say "ATM machine" or "department of redundancy department?" I feel your pain. Since the building industry has adopted the acronym BIM, it has generated a new phenomenon...the "BIM model." If you're reading this and thinking to yourself, 'hey, what's wrong with that?' then perhaps you mean to say 'building information model model?' Some of my friends and colleagues have suggested that saying 'BIM model' implies the verb interpretation of BIM so you get 'building information modeling model,' but I think that's a thin argument.

In an attempt to relieve some of our pain and mental anguish, some of us have taken to social media channels to clarify this sampling of techno-speak. John Tocci, Jr (@tocci2) tweeted: "Every time someone says 'BIM model' a fluffy kitten dies.' Being a big fan of dramatic statements as a vehicle to get a point across, I shared this theory during my presentation at the Washington, DC BIMForum and it seems to have gone viral. Check out the hashtag #fluffy_kittens.

The 'fluffy kitten' theory has even expanded beyond the borders of 'BIM model' into the realm of Levels of Development or LOD. Jim Bedrick now evokes the kitten theory when someone refers to an 'LOD### model.' This will be a full topic I'll discuss in a future post, but let's just say Jim gets equally upset with this as he does with 'BIM model!' Other folks such as Dan Russell from Sundt Construction prefer to apply a more positive spin to the kitten theory. Instead of 'killing kittens,' Dan says that every time someone says 'BIM model,' a coyote gets lunch!

Now, before you go out to the next BIM conference and start heckling the speaker by meowing every time he or she says...that phrase...let me explain a better solution to the problem. As an involved member of the National BIM Standard-US project committee, I have been a staunch supporter of the definition of standard terminology for industry BIM uses. Although BIM uses, workflows and information exchanges have been under specific development by buildingSMART international for quite some time, definitions were published in Penn State University's BIM Execution Planning Guidelines (bim.psu.edu). Without describing this effort in too much detail in this post, I encourage you to become familiar with these definitions.

Instead of abusing the redundant term 'BIM model,' perhaps we could start using some of the following terms:

Design Authoring model
Energy Analysis model
Existing Conditions model
3D Coordination model:
- Discipline Design Model
- Aggregated Design Model
- Trade Fabrication Model
- Aggregated Fabrication Model

Of course, the industry is gradually starting to look at model servers to support collaboration and information exchange, so these ‘model’ terms may be short-lived. In the meantime, do the world a favor and help protect our fuzzy, little feline friends...don't say 'BIM model.'

The July 2011 meeting of the New York City Revit Users Group featured a presentation by Robert Otani, PE, LEED AP and Jonatan Schumacher from Thornton Tomasetti.

By creating a collaborative dialog with the designer at the conceptual phase, the architectural, engineering & fabrication models can be developed simultaneously from the same geometric reference model, allowing a holistic design process. Robert and Jonatan elaborate on this concept with case studies of actual project work with a variety of architectural firms.

Thornton Tomasetti (TT) is an internationally recognized engineering company whose computational geometry and automation team works at the forefront of advanced practices. TT utilizes a wide range of commercially available as well as customized digital tools and automation procedures to model, simulate, and optimize engineering projects of various scales worldwide.

Helping Shape the National BIM Standard

2011-06-28T21:56:00.001-04:00

One of my 'little' side projects has been getting involved in some efforts at the buildingSMART alliance. Last year I began by participating in a group project to standardize cost estimating through the use of BIM. As you can imagine, that's an extremely difficult problem to solve and our efforts continue. More recently, I was asked to become involved with the National BIM Standard project committee for the United States. Given my prior experience with corporate standards at SOM, I agreed to join.

Since joining, I have been named the Chair of the Design Work Group for NBIMS-US version 2. Yes...in case you didn't already know, version 1 was completed a few years ago and can be downloaded for free from the buildingSMART alliance website. While the first version consisted of almost 200 pages dedicated to introducing the work of the NBIMS committee and the scope of BIM, it did start to address some key concepts towards the standardization of this oft misunderstood paradigm.

Definition of BIM - Let's all agree on what "building information modeling" really means, shall we? NBIMS v1 describes it as "a product...a process...and a result."

Importance of Data Models - Quite a worthwhile chapter for the technologists among us, but this sets the stage for adopting the IFC data model. Notice I said 'data model' and not 'file format.' this will start to open the discussions concerning model servers instead of interoperability of proprietary file formats.

Capability Maturity Model (CMM) - This is one of my favorite parts of NBIMS; however, it is my opinion that the CMM needs some refinement. Our industry needs a leveling system for all stakeholders to gauge the completeness of a deliverable or a firm's ability to deliver expected services. Well, exactly what services are we talking about?...Standardized BIM use definitions have been submitted for consideration in NBIMS v2, but that's worthy of a dedicated discussion. There are many parts evolving from this concept that should help bring an 'apples to apples' approach to BIM delivery.

These are but a few of the items we are reviewing in the work of the four NBIMS work groups (Design, Assemble, Procure, Operate) along with the Implementation and Technical Sub-Committees. I'll be posting more about our progress and I encourage you to provide feedback.

You can also get involved in the NBIMS effort. While the official ballot phase for V2 has closed, you can submit a Blue Sky ballot. Any good idea can be submitted via a simple form - and you don't even have to be a buildingSMART alliance member! Please visit the balloting page for NBIMS to get involved and view the active ballots.

Getting Ready for AU 2010

2010-11-24T03:38:00.001-05:00

If you’re heading out to Las Vegas for Autodesk University next week, I’ve compiled some links to some great preparatory information.

Melanie Perry (aka Mistress of the Dorkness) has a funny, but totally true AU survival guide on her blog. Lynn Allen produced two '”primer” videos on YouTube (Part 1 and Part 2 available below).

Being environmentally friendly, Autodesk does not provide printed handouts for classes – except for hands-on labs – so, here’s how I’ll be going paperless this year…

First, the devices: iPhone 3G and iPad – should cover most of my connectivity, tweeted photos and note taking capabilities. Not sure if my laptop will follow me around full-time.

Second, the apps. My favorite all-around app is Evernote. With a limited free account, I can create notes on either the iPhone, iPad, PC or web browser and they are all synchronized. Seriously thinking about upgrading to a Pro account… This is essential for capturing all my notes from the plethora of great class offerings. It offers text/audio/photo notes, tagging, search and a variety of other features. If you’ve read Total Recall by Gordon Bell, you know that Evernote is frequently referenced as one of the main offsprings of the LifeLogging movement. If you haven’t read it…find it on iBooks now!

Don’t expect to receive a printed event guide this year either. Autodesk is offering a mobile app from EventKaddy. The app will be available for iPhone, Android and Blackberry and should be ready as of Friday November 26.

I have downloaded my class handouts into my Dropbox account which also has apps for iPhone and iPad. This gets the files onto my mobile devices, but I highly recommend GoodReader for the iPad. It fluidly reads a variety of document formats and has nice markup tools. It also can display documents externally with the VGA adapter. Open a file in the Dropbox app and click the link in the upper-right to open in another eligible app. Finally, I’ll be keeping track of the tweets via Tweetdeck on either the phone or pad. (www.twitter.com/jvandezande) Also be sure to follow @AutodeskU and the hashtag #AU2010.

I hope to see you there. It’s always been fun meeting readers of my blog, so don’t be shy…come say ‘Hi!’

Special events and navigating the conference

Event Recap: BIMForum Atlanta

2010-10-25T11:01:00.001-04:00

Note: My conference notes were captured exclusively via Evernote on the iPad!

In my last post, I shared just a few pictures from the first pre-conference event at BIMForum Atlanta. In this article, I will summarize the experience of attending my third BIMForum event. In prior years, I had participated in this conference in Falls Church, VA and Dallas, TX – both of which were definitely worth the trip.

This time around, the AGC stuck with the modus operandi of a themed conference. Held at the W Hotel Midtown, the theme was “The Evidence of BIM” or “The Evidence on BIM” – depending on which handout I was reading…perhaps an interesting typo, but I digress. As always one of the main benefits of this type of event is the face-to-face networking - especially outside my ‘comfort zone’ of BIM management. The BIMForum touts one of the most diverse audiences that I’ve seen to date. A quick survey by BIMForum chairman, John Tocci, indicated an even mix of architects, engineers and contractors with a smaller contingency of those representing the owner & facility operating community.

Now, back to the theme…which I’ll simplify as “Evidence” for the sake of this article. The initial marketing leaned towards providing case studies of firms and organizations using or requiring BIM and the benefits they are realizing as a result. Presentations were delivered from a variety of industry sectors, some of which didn’t seem to fit within the “Evidence” theme. I now realize this is not necessarily a bad thing. Recalling the Dallas conference, the overall theme seemed to be forced into the last few slides of EVERY presentation, whether the lecture had anything to do with the theme or not. For that, I’m thankful.

Before I dive into a more detailed review of some key presentations, please note that some or all of the presentation material should be available on the BIMForum.org website soon.

BIMForum Tours

What has become a staple of these conferences, I signed up for the pre-conference BIM tour. This time we visited the campus of Georgia Tech, a really beautiful university that is close to downtown Atlanta. First we were lead on a tour of an addition to the school of architecture being constructed by Beck Group. Of interest was the fact that they assumed the role of the subcontractor for the furniture contract and used some interesting tools and techniques. They had quite a learning curve as they worked with point clouds from laser scans of existing stairwells to append new millwork rails. The workflow seemed a bit convoluted (Rhino to Inventor to EdgeCam to CNC Router), but ultimately was the best available to the team.

The second part of the tour brought us to the Digital Building Laboratory with Chuck Eastman. This is a large facility that was formerly dedicated to advanced wood engineering, but is transforming into research of other materials such as precast concrete and masonry. You can read more about their expertise and projects at www.dbl.gatech.edu. Of note is a new masters degree program being offered next year called Master of Science in Digital Design and Fabrication (MSDDF).

Conference Day 1

Back at the W Hotel, we began the conference with a variety of presentations kicked off by Debajyoti Pati of HKS speaking about evidence-based design. He stressed the importance of the role of the designer in identifying the strategic goals of their clients. Based on results from the medical field where research is used in an attempt to reduce preventable deaths at hospitals, Pati suggests that energy performance predictions will improve occupied facilities and clash detection methods will enhance the construction process.

From Georgia Tech, Chuck Eastman discussed the work he has been doing with GSA in simulating and analyzing circulation routes in early design models. He and his students have also been using Solibri to translate models for use in energy analysis software. This is an interesting departure – using a model checking program – instead of using a direct API tool for exporting or relying on IFC. Ioannis Brilakis spoke about his research with automated real-time videogrammetry (ART-V). You really have to check out more info at the Construction Information Technology Laboratoty (citl.gatech.edu) to fully understand the importance of this technology to the industry! Jochen Teizer also spoke about his work with the Real-Time Automated Project Information and Decision Systems (RAPIDS) lab which can be found at www.rapids.gatech.edu.

Bruce Hunn from ASHRAE gave a presentation about performance measurement protocols for commercial buildings which was interesting, but a bit of a dry topic. I’ll be sure to collect his slides for future reference if they are made available on the BIMForum website. Following Bruce was Josh Oakley and Frank Fralick – who were our tour guides from Beck on the school of architecture construction project.

Hilda Espinal and Chitwan Saluja from Perkins + Will discussed three of their recent BIM projects using varying degrees of collaboration with others. Nothing too new here, but I was curious to know more about their discussion of contractors making requests to them for modeling adjustments. If the designer is doing more work to help the contractors do less work…how much extra was P+W getting paid? I’m sure I know the answer to that.

Brett Young from Cahill Contractors spoke about their use of BIM – although I didn’t really see how it applied to “marginally historic buildings” as the presentation title stated. That said, Cahill’s main business is in affordable housing in California. They have been using BIM to improve their bottom line in constructing these building types. Two interesting factoids from this presentation: they point clients directly to the Penn State BIM Execution Planning site to better understand the defined BIM uses; and, in understanding the potential additional cost of asking their subcontractors to provide BIM, they stated the highest cost is related to increased meeting requirements resulting in additional labor costs.

They also mentioned one or two projects where they used a 3D model to discover egregious errors in the architect’s drawings. This is something that is a pet peeve of mine – some architects have seem to lost sight of their responsibility to provide coordinated designs. Just because you’re using a BIM tool, doesn’t mean that your designs are automatically coordinated!!

Harry McKinney and Scott Cutler from Clancy and Theys Construction spoke about “How BIM Attracts and Inspires Unexpected Uses” – an interesting look into the application of BIM to a science museum with a large sphere incorporated into the design. They spoke about presenting the model to museum stakeholders, using clash detection to find interferences with exhibits and problems with the vertical clearances (hello, architects?!!). The model was also used to detect quirky maintenance and service issues behind the spherical screen structure before they became real problems after occupancy.

To conclude Day 1, John Moebes from Crate & Barrel delivered yet another inspiring talk about “An Owner’s Changing Use of BIM.” Back at the Dallas BIMForum, John gave a somewhat vitriolic view from the owner’s perspective towards the AEC community seeking to be compensated for their use of BIM. This time around, he shared some fantastic views on efficiency and productivity. His team’s construction schedules are being reduced from 88 weeks to about 56 weeks with a goal of reducing it to around 40 weeks. They can accomplish this by a new method of delivery Moebes refers to as “design – build – bid.” This seemingly odd sequence actually make perfect business sense. Get your critical path trades (foundation, superstructure, electric, enclosure) done with pre-arranged partners, then put the remaining trades out to bid for local contractors. I could go on and on about John’s proposed “AEC moon shot” but you can view one of his recent presentations recorded at KA-Connect in Chicago to get a taste of his motivational techniques.

Conference Day 2

The second day of the conference was an extended panel presentation by a selected group of owners ranging from Target, to Worcester Polytech, to Sandia National Labs. To lead off the discussions, Karie Johnson from AEC Transormations spoke about her work in defining BIM requirement documents for owners. Johnson used a creative reference to the Dr. Seuss character Sam I Am as a segue to a ‘Should you? Would you? Could you?’ presentation about the do’s and don’ts of these types of documents. She has reviewed many documents and shared some really bad passages from them – definitely worth asking for a copy of her presentation for a good laugh.

Guillermo Salazar and Alfredo DiMauro from WPI spoke about their use of BIM on campus, which was somewhat similar to the afternoon talk delivered by Colleen Kasprzak and Ed Gannon from Penn State University. Here you have two organizations with enormous building asset portfolios who are starting to grasp the value of the information – the ‘I’ in BIM – as it relates to operating, managing and maintaining their facilities. One metric referenced by the Penn State presenters was that even a 10% improvement in the productivity of work orders would result in about $3 million dollars in annual savings.

Steven Wolf from Target spoke about his organizations plan to start implementing BIM for construction of new stores. Target’s design and construction process is almost completely based on a highly customized Bentley Microstation environment. Wolf stated that it was a challenge overcoming the strategic difference between the business leaders (“Exactly how are you going to measure your success?”) and the architects (“We like BIM because it’s cool!”) in developing an implementation plan. One interesting area of research they are pursuing is in the improvement of code reviews. Target spends $40-50 million a year in change orders associated with inconsistent interpretation of local building codes. In addition to working with the ICC on guidelines for replicable buildings, they are working with Avolve Software (makers of ProjectDox) on the development of ePlan review technology.

Finally, Birgitta Foster of Sandia National Labs closed the series of presentations with a look at the value of BIM for facilities management in what she calls “Design for Maintenance.” Foster shared some metrics in a similar thread to the earlier statements by Penn State and WPI. First, we were treated to some visual comparisons of mechanical equipment installed well and some not so well. What went wrong with the latter? Given simple, single-line diagrams and unrelated specifications instead of a 3D model and/or diagram, designers and engineers may leave real coordination up to the contractors in the field. Without an intense 3D understanding of a complex mechanical installation, a design team can unwittingly add to the lifetime cost of maintaining it. Foster offered a sample work order template form which indicated a number of hours to service a piece of equipment with “easy access” and double the hours for “hard access.” It’s issues like these that can easily make the case for the requirement of BIM from the owners’ side and clearly delineate the place of the design team in coordinating the effort before construction.

Conclusion

The owners’ presentations were concluded with a lively panel discussion, which also included John Moebes from the previous day. Moebes was asking MEP engineers why they won’t do LOD400 models, citing the common response is that they assume being more specific would be costing the client money by avoiding a competitive bid. He argues otherwise, that he’d rather be able to efficiently procure a known system than rely on a field installation of a prescribed design.

An interesting take on implementation, particularly at larger organizations, is that amidst larger changes BIM can be the smallest diversion. One final note of interest to the A/E community is that a few references were made to organizations that are beginning to embrace how BIM can change the traditional design process. Ohio State reportedly will pay design fees earlier, but not necessarily more. The Commonwealth of Massachusetts is willing to transfer some contingency costs to the design team if BIM is used to reduce some of the unknowns related to traditional methods. It’s all about speed, but at the same fee.
