Borrowing from HOK

2012-01-27T08:18:00.003-05:00

As we've been preparing for our impending atomization (130 days - 07 hours - 22 mins - 19, 18, 17, 16 sec to go), I've been paying close attention to how a few other firms are managing decentralized standards and incentivization.

I've been really intrigued by HOK's internal BIM Certification, and now their BIM Awards program. I might have to borrow some of these ideas...thanks James!

Still Talking About "What is BIM"

2012-01-27T07:41:00.002-05:00

This is a cute video, but I don't know that it adds any clarity to the discussion. Plus, by my count, 7 fluffy kittens were killed in the making of this video.

Mmm..Chocolate

2012-01-23T08:49:00.003-05:00

What better for my first post of the year (and my first post since last July!) than chocolate?

While Gizmodo might imagine printing out a chocolate Easter bunny any time of the year, I envision prototyping facade details. The rejects would be the perfect snack.

A 3D printer is in our future, perhaps I can convince John that the Imagine 3D printer is the right one for us.

Although I'm always more excited about iPad apps for construction (we're up to 5 in use in our department!), here is a comparable list for the Android.

I'm in the process of listing out the Tocci recommended iPad applications for our internal users - although my list won't be nearly as exhaustive as Derek's, I'll post it as soon as I find the time to finish up!

Revit Top Cat

2011-06-06T14:03:00.004-05:00

We always wonder how to assess someone's Revit skill, but never really feel the need to implement anything - given our integrated team of power users. Maybe this is it.

I found it interesting that a Revit MEP user won; I'm not too surprised, I think Revit MEP is more technically demanding and requires that you know how to use quite a few features in Architecture/Structure.

This actually might be an interesting internal exercise - bring out everyone's competitive streak...

Countdown to Atomization

2011-06-03T11:09:00.006-05:00

It's official: the countdown until the end of Tocci's VDC department is running! About 6 months ago, we decided to explore "atomizing" our VDC department, deploying VDC staff to roles in Cost Engineering, Project Management and Field Operations. Our team already serves hybrid roles on projects, with some functions overlapping between more traditional roles. Looking more closely at this, we determined that the only way to further integrate VDC into our process was to decentralize it. So, by June 5, 2012 (at 5pm), our VDC department will be no more. About 80% of the team will transition to roles in the departments mentioned above; the remaining team will figure out how to maintain innovation, standards and training in a new department (to be named later!) without becoming arbitrary or standing in the way of projects. Or maybe, everyone will transition out and we'll figure out the rest later! More updates as the clock counts down.

Cautionary Tale? or Alarmist Scare Tactics?

2011-06-02T06:54:00.001-05:00

[From CCC]

Another piece of tenuous journalism has recently been making a buzz in the industry, attempting to discredit the remarkable progress of IPD. A buzz, however, is all that this lackluster movement can muster against the force that is transforming the industry in positive directions not seen in decades. If you have not yet read the piece, you can find the link below as well as John Tocci’s response.

A Cautionary Digital Tale

John’s response:

Nadine, Nadine, why do you do the things you do? This is yet another article with a scary title but vacuous text which fails to support the title’s chilling claim and sends the unknowing screaming down the road like an Edvard Munch painting . We know at heart you are not an enemy of professional progress and collaboration (quite to the contrary) but it’s hard to see this from the steady diet of fear-filled articles such as last May’s “IPD…Flashing Red Lights” (complete with a toxic IPD cover page) and webinars like “Goodbye IPD, Hello ID”. Citing unspecified IPD risks and fears, the webinar promised a fairy world of IPD benefits while maintaining conventional (defective) contracts. Not.
Back to this article, one has to ask, why would any author rely on a ‘fact set’ from a single, non-expert source such as the PL carrier, especially this one? The other commentators (who responded to the web posting) rightly observe the true facts; this case (at least as presented here) has little or nothing to do with BIM and everything to do with disciplines continuing to act in silos of isolation, blame and self-interest. Moreover, we fully agree with the commentator who laments the article’s probable effect on liability insurers and others (“…running scared from BIM”).

The devil needs no additional advocates. Unfounded fear abounds in the oceans of ignorance. And the status quo needs no defense. What we do need is solid journalism with validated facts to help us restore a once noble profession and join our industry’s efforts to emerge from litigation and dismal performance– not another horror title. Help us will ya?

Tekla BIMsight

2011-02-16T11:27:00.003-05:00

If you haven't tested Tekla BIMsight yet, you truly have no excuse. It's free. Not 30-day trial free. Completely free. After seeing a demo last week at the BIMForum, our team had to test it.
The interface is amazing; clean and intuitive. It's fast and it's easy to use; you package a file for someone and have them viewing the model in about 30 minutes (install, training videos). Functionality basically includes clashing and measuring; you can view some parameters, but not all.

So what is it missing? No way to group clashes, manage clashes or print/export reports of clashes. No way to group views, which could get messy when we create thousands of them (and we will).

I can see teams using this for basic design coordination, whether its our team or the design team. (No excuse for having any clashes in 100% CDs if you have a free, robust clash tool.)

I can also see us having our supers use this. They've already been trained in Navisworks, and then Navigator, but why not throw another BIM software at them! Its intuitive enough and could be a great way for them to start using the model on their own. They can do a little clash detection if they want.

Do I see our VDC team using this instead of our current solution? Probably not. Without clash management, exporting functionality and collaboration capabilities, it would be tough to use.

Is it perfect? No, of course not. Do we have things we want to change, add and expand on? Always. But..its free. And so usable. So we'll find a way to use it!

Laser Scanning Clinic at BIMForum

2011-02-09T17:49:00.013-05:00

Instead of the tours that we've been doing at the BIMForum, we did a laser scan clinic reviewing the practical steps to laser scan and convert to BIM.
We started with a presentation, but quickly moved to a demo of the new Faro scanner after we started with Q&A. It was great to see the entire process, from scanning to registration to clean-up of noise.
We're in the process of testing different LAM (laser-scan aided modeling) workflows, so were excited to add a few to our list as we're currently testing Scan-to-BIM and a few other platforms:

We've been talking about testing out the Faro (we've been using Leica), so the demo of it may be what pushes it over the edge to start really testing.

What's Next

2011-01-31T12:08:00.001-05:00

After reading this article and all of the comments, Sam Stuart, one of Tocci's modelers, had to respond:

People will automatically get nervous for fear of becoming antiquated when a new technology or a new way of working presents itself, especially in a field like construction where the same working principles have been in place since the Romans were building.
First, people need to understand that BIM and IPD are two very different things, and are not mutually exclusive. IPD is a project delivery method, and as effective as it has been found to be, was not a subject matter of this article and can be debated fully at a later date.
BIM, however is a virtual representation of an actual deliverable, as opposed to the historical methodology of delivering a 2D abstraction of a design intent. This virtual representation allows architects to better interact with what they are producing, and can allow for more control over the final product, as it allows a 3D experience as yet unavailable in 2D documentation. This also allows Architects to actually control design intent through virtual manipulation, which in the long run is much less costly to the project than controlling design intent trough actual manipulation in the field, which is unfortunately the norm. This practice of creating "virtual mock-ups" or details, can greatly reduce change orders and rfi's and focus the team on actual conditions rather than abstract notions.
Second, there are also plenty of directions BIM can be taken where it is still in it's naissance, as Mr. Barrett points out. Whoever is contractually responsible for coordination (also not a subject matter of this article) BIM is a tool that has and will continue to revolutionize the industry in many more ways than just that. The idea that an Architect/Engineer/Contractor can work with a virtual model to refine design and systems prior to actual execution can lead to not only updated coordination methodology, but also off-site prefabrication, as well as other, information based operations that can lead to better, more efficient buildings that are built in a better, more efficient way.
The idea isn’t to make anyone obsolete, but rather to use the technology that has been around in other industries for a number of years to make this industry better.

Hiring!

2010-12-28T16:52:00.002-05:00

Okay, to be honest, we're always hiring, but we need to bring the right person on for this position ASAP! The title isn't quite what I want it, so read the description to get a better idea. Oh, and if you have a better title for this, send that along, too.

Tocci Building Corporation has been implementing Virtual Design & Construction (VDC) since 2006; we’ve moved past the BIM basics (clash detection, quantity extraction and logistics) and are well on our way to total transformation of the way our company executes work. We are expanding our team to support current projects, pave the way for new utilizations of BIMs (like field layout, code checking, prefabrication, and 3D printing) and define new project relationships under IPD contracts.

Job Title: VDC Technology Manager

Department: VDC

The VDC department creates building models (BIMs) to be used in preconstruction and construction, as well as supports the use of those models. Although we’re receiving Revit models from design team members on most projects, model clean-up is usually required to actually use models for construction. Most model clean-ups or 2D conversions are done in a team, comprised of internal team members or design team members. Models are created with actual construction use in mind: quantity extraction, coordination, additional documentation and direct-from-model execution.

Position Description: The VDC Technical Manager is a key position in Tocci’s VDC Department, responsible for the management of Tocci’s VDC software and technical standards.

The department current uses Revit Architecture/MEP, Bentley Navigator, Bentley Projectwise, Solibri, Navisworks, Manage, AutoCAD MEP, and other VDC software programs. The VDC Technical Manager is a user of all of these software programs, so that each can be supported and optimized. Because new VDC software comes out every day, a key part of the VDC Technical Manager position is testing new software programs and functionality to make sure we are using the best out there.

The VDC Technical Manager’s time is split approximately 50/50, spending half-time on standards, software testing and management and the other half-time on project work.

The position requires a self motivated, detail-oriented, open-minded and dedicated individual that has an intuitive sense of the constraints and opportunities relating to VDC. Successful candidates will be prepared to emotionally engage with Tocci and its projects. The position is based in Woburn, MA, but travel to jobsites and partner offices for co-location throughout the country (mostly in the Northeast) is required as needed. The position reports to the VDC Manager.

Essential Duties and Responsibilities:

§ Maintain Revit templates, standards and libraries

§ Develop and maintain Bentley workspaces and DGN libraries

§ Maintain graphic standards manual and perform QAQC on department/project deliverables

§ Create training materials and conduct training sessions

§ Test and implement new software tools and technologies

§ Develop internal capabilities for 3D printing, CNC equipment, RFID tracking and tagging holographic printing and other emerging technologies

§ Stay up to date on software features; train team on new features and how to appropriately use

§ Work on projects, performing tasks including:

§ Work on teams developing & coordinating BIMs, collaborate with design professionals to co-create models and perform quality assurance/quality control checks on BIMs

§ Work with cost engineering staff to develop accurate and easy-to-use quantity takeoffs

§ Work with project managers to optimize schedules through visual scheduling

§ Develop supplemental field documents for superintendents

§ Develop photorealistic renderings and walk-throughs directly from building models

§ Work with project managers and superintendents to update models to reflect as-built conditions

§ Understand and promote Tocci’s VDC process through internal and external training and presentations

§ Perform other tasks related to Virtual Construction implementation

§ Participate in general office “chores”, including emptying the dishwasher, moving boxes, decorating the Christmas tree or re-stocking soda in the fridge. Tocci is very much a family, so we all pitch in.

Qualifications:

§ Minimum Bachelors degree in architecture or construction related field or equivalent work experience

§ 3+ years in building or design industry required; work experience with VDC or BIM using Revit desirable

§ Preference will be given to candidates who are Registered Architects or Registered Engineers.

§ Exposure to and experience with Building Information Model (BIM) systems (i.e. Autodesk Revit , Bentley BIM, ArchiCAD) required

§ Individuals with experience using non-Revit software programs will be prepared to transition to Revit

§ Must be organized and slightly OCD

§ Excellent technical skills, including using computers, the internet and file sharing required

§ Strong personal management skills, dedication, organization and open-minded required

§ Creative thinker with ability to work in a close knit environment with like minded personalities

§ LEED AP preferred, but not required

Please submit resume, references, and salary history to:

Not that SketchUp is BIM, but..

2010-09-28T14:52:00.002-05:00

I don't actually think that SketchUp is BIM, but some people are saying that it has some potential, especially with the new release.

Fascinating.

Autodesk & Vela

2010-09-02T08:13:00.003-05:00

Not necessarily surprising, considering how important construction has become to BIM software vendors recently. Will be interesting to see what happens with Autodesk &Vela in the future.

ImageModeler

2010-09-01T08:14:00.005-05:00

ImageModeler was presented to me last year as a cost-effective (albeit less accurate) alternative to laser scanning for document existing conditions. We started looking at it last year and found some limitations. Since I have read a few blog posts about it recently, I asked the modeler, Pierce Reynoldson, who tested it to share his thoughts:

ImageModeler 9 (IM) is a powerful tool for generating photorealistic, image-mapped 3D models from 2D photography. It reproduces 3D space by calibrating corresponding 2D points between multiple photographs, a process called “photogrammetry.” Once the 3D space is defined, you can “trace” 2D objects within the photos using 3D modeling tools.

We got the idea that IM might also be used to accurately document built and existing conditions for construction. If so, such a tool would be an inexpensive, in-house alternative to laser scanning. However, after two weeks of tinkering, tutorials (Autodesk and third party) and field tests, we found that despite our best efforts this is simply not one of IM’s current capabilities. To be clear this article is about our attempt to leverage IM for a purpose it was not designed for and not a criticism of the product itself.

The crux of the problem is that BIM ready field documentation needs to have a certain level of reliable accuracy. IM was designed for visualization and, as such, produces minimally accurate geometry. As we field tested the limits of IM were apparent at every step, but we kept developing workarounds in the hope that we could bend IM to our will. IM, to its credit, stood strong.

First, simply capturing the right photos (photos that show complete edges of the building, from roughly the same distance and with minimal occlusions from surrounding elements) is a real challenge in the large scale world of buildings. Even if you manage to capture every edge of the building with the minimum of photos (calibration starts to become unmanageable after 12 photos) you will be unlikely to model detail elements from the same set of photos used for overall massing. (The work-around for this is to model details in separate files and combine them in another software; unfortunately, this effectively multiplies discrepancies of scale and alignment). Whatever quality the photos, calibration and modeling are ultimately limited to a screen resolution of 4096px X 72dpi that does not improve as one zooms in.

Modeling itself is another challenge. Objects are generated from manipulating subdivisions of primary solids – for those familiar with 3DSMax, this probably sounds fine. Unlike 3DSMax though, these tools are very basic and have limited snapping capability. Modeling of complex shapes is difficult and tedious. Modeling with reliable accuracy is practically impossible.

For field documentation, the model should be accurate to at least ¼”. IM can produce a model with accuracy down to maybe ½”. For larger the objects (say the 220’ long building I work in) the accuracy is more like 2”– 3”. Simply not good enough for construction.

The final limitation is exporting the model. IM models export as scale-less DWG’s with no origin. Thus, separate IM models must be aligned and scaled manually. IM to DWG geometry is NEVER orthogonal, though, which means Revit will not like the walls generated from an IM mass. Finally, even if you made it this far, geometry loss during import is common and difficult to prevent.

Generating accurate real world documentation is not IM was designed to do. If you have watched the marketing videos, what it does do is actually pretty awesome. If Autodesk is interested in taking this software in the field documentation direction, they will run into competition with PhotoModeler, which incorporates more sophisticated camera calibration and utilizes coded field targets. For visualization I am sure most find IM’s stripped down workflow perfectly adequate; especially for something that came free with your Autodesk subscription.

Innovation Through Challenges with BIM

2010-08-13T06:13:00.003-05:00

Recently (okay, 3+ months ago), I read this article, by Hilda Espinal, Director of IT Design Applications at Perkins+Will, which I have been meaning to share. The article details how the BIM was used on the Rush University Medical Center and some of the challenges that the team faced as they utilized BIM. I always appreciate when teams are willing to share the challenges as well as the successes, as the "lessons learned" stories seem to be the most interesting and valuable. There are a lot of great thoughts in the article, but I really like how Hilda concludes, discussing the benefits versus the challenges of using BIM on the project:

Not so long ago many of us would have considered the use of BIM in a project of this magnitude and complexity as quite irrational and in some cases impossible. Today, for the exact same reasons, it is hard to imagine executing a project delivery without it.

Amplification (and Hiring Evaluation Criteria)

2010-08-05T17:54:00.003-05:00

Most of my favorite blogs, especially recently, focus on business and leadership concepts rather than BIM. A recent post on Presentation Zen detailed some interesting thoughts from Pixar that resonated with me on a few different levels.

Our industry talks about collaboration quite a bit, but often when we dig in, we aren't truly collaborating. I haven't really thought of a great way to communicate that idea internally or externally, but when I read what Pixar had to say about it I knew that it was what I was looking for:

Cooperation is not the same thing as collaboration. Cooperation is just that thing "which allows you not to get in the other's way," says Nelson. Collaboration means amplification. ... I think of collaboration as being like 2+2=5 (or 137, etc.).

I also love how they talk about hiring criteria. Since we've been actively hiring for two VDC positions, we've gotten so many resumes from people who know Revit, and probably know it quite well, which is exciting. However, we aren't just looking at "depth" of knowledge in Revit because most of the work that a new hire will do is undefined, because we are constantly pushing the envelope. As it is put in the Presentation Zen post:

...how do you hire someone for something that has never been done before? ... past success alone is not enough
Pixar looks for experience with "failure and recovery", along with an entire host of qualities. I like to think that we are doing similar things. It's about problem solving, working in a team, culture fit, negotiating and a sense of exploration.

I'd be interested in what other people look for when they hire, whether for a BIM-related position or something else.

Guest Post: Information is a Paradigm Shift

2010-07-16T11:02:00.000-05:00

Since I have gotten worse at frequently posting, a few people have offered to help keep (bim)x a little more alive by writing posts when they are inspired. Here is one, from on VDC Manager who has decided to post by a pseudonym: VirDC. Thank you for sharing your thoughts!

Laura Handler has graciously offered to open-up her blog for an occasional, anonymous blog post, just to keep her readers on their toes. Thank you Laura, for giving me such a prestigious podium! The past few years have been a mad scramble for many of us getting a foothold in the AEC industry and I've found great comfort in the priceless contributions that you and your fellow Toccisti have made to our industry my developing career.

I hate to start my piece as just one more take on where BIM is taking the AEC industry, but I may as well get it out of the way in my debut post with some really cool links. Anyway, it's been bugging me that some people have analogized the adoption of BIM with the transition from hand drawing to CAD. Though I love history and I believe there are always lessons yet to be learned from the past, there has really never been a true paradigm shift like we are experiencing. If you aren't seeing it, you may want to figure-out why you aren't seeing it before it's done and position yourself accordingly.

For the past few years, everything's been a bit wild in the AEC industry and not just due to the economy... While the industry finally hit full stride with the Green movement, there's been a much more tumultuous undercurrent welling-up that is changing the way the entire industry is structured and it's only amplified by the poor economy. As anyone who follows this blog knows, information and technology is what is transforming the industry by way of relational, object-oriented programming that simply allows us to relate various information, relate that information, and produce information that has additional value. Call it BIM, PLM, or even ERP if you want, but is finally transforming the way we use computational power to assist us. Yes, I say finally because not only has it taken a long time for it to get from this guy's head to your fingertips, but it is essentially the limitless transformation sought by creative minds for millennia: a way to turn pure creativity, knowledge and resources into an informed reality.

The more we harness information, the more potential uses for the derivative information there become. We have only just begun to conceive of the ways information can be used in the real world to influence design, construction and results, but there is literally limitless potential. We're just not likely to be able to identify many advanced uses from the outset: clash detection, code compliance, takeoff quantities, costs, etc are only the very early beginning. Frankly, it's a little bit scary to consider some implications. For instance: if we tie quantities to costs and tie those costs to an online marketplace, are we really just commoditizing the industry and extracting the "Hu element?" Would a commodity market dynamically tied to a design really take material costs off of the list of variables forever? I doubt it, but I can't say what would happen if nearly every designer/planner had that level of information at every step. Predicting the usefulness of information just one or two steps out with any degree of certainty gets pretty nebulous like predicting the weather, the economy, or the climate for that matter. But, what I do know is that we will continue to push ahead and the use and application of derivative information will not grow linearly.

Today, we struggle with data workflows to leverage basic information, interoperability of data, detection, isolation and correction of bad or flawed data, and the human interfaces to that data. But, the seeds of a different growth pattern have already taken root. Before long, we will have worked-out a defined modularity for new, extensible data, thus resolving interoperability and making workflow objective rather than subjective. We will have a slew of intuitive and fully-customizable interfaces to capture our every inspiration and truly dynamic, proactive and predictive feedback on design and logistics. Possibilities will mean something else entirely... just look at what Wolfram Alpha is doing with relational data. It's just the beginning.

Virtual Reality

2010-07-15T14:01:00.002-05:00

I skimmed this recent article AECbyte article to see what I missed at the AIA Convention and noticed that the article missed something I had heard about: Virtual Reality for the AEC industry.

We tested a previous version of this solution a few months ago and were very excited about the potential of it. Now it looks like WorldViz, the company we are working with, has released an AEC-specific toolset and showcased it at the AIA Convention. We are probably going to implement this for one of our clients; is anyone actually using this on projects right now?

Simultaneous Analysis

2010-07-13T09:37:00.002-05:00

Last week, one of Tocci's VDC Modelers sent this article to our team, on AIA New York's Shifting Paradigms: Design in Transition event.

The discussion point in the article that stood out to me was not the "insecurity of the audience"; it was Paul Seletsky's criticism of BIM software, which does infact "lack the ability to simultaneously look at design geometry and energy management". I would extend that to any type of analysis. For instance, even though we are able to extract quantity information directly from a model to feed an estimate in a much shorter time period, it is certainly not instantaneous pricing feedback.

Where our success has been is in finding workarounds that create "almost-instantaneous" feedback. Obviously these workarounds require setup and BIM Execution Planning, but short of improved interoperability and connectivity between software platforms, its what we have. And although it isn't perfect, it is certainly better than traditional process.

Cutting Edge

2010-05-21T10:19:00.007-05:00

While Jeremy was at the Green BIM conference, I attended the annual Bentley conference, BE Community Live with two other Tocci modelers, Sam Stuart and Courtney Pagani. Although we all have pages of notes, lots of ideas and lots of things to test, we were most excited by one corner of the exhibit hall: Future Technology.

Bentley does a lot of amazing R&D, but we were especially excited about what they are doing with QR codes. I think they are sending out some videos, but in the meantime my horrible cell phone pictures and brief text will have to suffice.

QR codes are driving model navigation. The laptop's camera is synchronized to the model, so that as the laptop moves in space (rotates, moves back or forward) it registers to the QR codes and navigates through the model.

Here QR codes on a 2D plan help overlay a model in the camera view on the handheld device.

One thing that I didn't get a great picture of was the integration of all of this into an iPad, using its internal GPS. The model was navigating merely by moving forward, backward, etc. That technology combined with location-based navigation will be very powerful in the field.

Fabricator's Perspective

2010-05-21T08:55:00.005-05:00

Earlier this week, one of Tocci's modelers, Jeremy Garczynski, attended McGraw Hill's Green BIM Conference earlier this week. Although the definition of green was a little inconsistent through the day (yes, we agree that efficiency and reducing waste is green, but clash detection as green? that's a stretch), the notes that Jeremy sent out to the Tocci VDC team were very interesting.

One presentation specifically caught our eye - the presenter from Zahner, a BIM-enabled wall panelizer specializing in metal surfaces. The project they spoke about was the Art Gallery of Alberta, where they modeled the wall panels for fabrication and used robotic total station to position the panels. Although that process is becoming more common place, I'm still amazed to see subcontractors doing on projects like that (although come to think of it, I don't know how someone would do it otherwise!). I also found this article on the construction process.

As I was researching Zahner, I found a BIM article on their website. While it could use a little imagery, I love their perspective and the way they talk about the process - probably because it's exactly how we talk about it internally:

"Like a growing leak in the dike of ingrained conventions, the integration of digital technology is dissolving the barriers that slow down the building process. Companies that do not embrace this technology will be overwhelmed by the shift that is occurring."

"Litigious concerns for who is responsible for checking or validation are less and less an impediment."

"You can see it in the eyes of those that work in the process. Being part of creativity is fun and satisfying."

Virtual Reality

2010-05-05T09:06:00.002-05:00

About half of a dozen people email me this article last week on how virtual reality is being used for training. I would have loved to learn more about the technology, the interface, etc. but it was still very cool to read.

Our team read it and posted some thoughts on Tocci's blog, coolcalmconstructed.com.

Building Taxonomy

2010-03-03T00:58:00.002-05:00

So first I read the article recently posted on AECbytes:

Although I love the idea of a taxonomy to discuss building systems, it seemed that the taxonomy described in the article doesn’t reflect the direction of the industry. Whether using Dickens’ “21 Building Systems” or another system (perhaps the increasingly used Uniformat II Elemental System), systems do need to fit into a variety of delivery formats: from design-bid-build to IPD. However, the focus of a taxonomy (especially a new one) shouldn’t focus on more conventional delivery methods as it is unlikely that entities using those aren’t likely to change. Although the article doesn’t ignore an integrated approach for all project activities, it is only briefly mentioned – after a longer discussion of the use of a taxonomy in a design-built-bid scenario.

My suggestion: think about a taxonomy that can be used for a range of integrated teams. It isn’t a taxonomy for architecture; its a taxonomy for the design and execution of built projects.

Then I read the comments on the blog, and just commented this:

I have to be honest - I wrote my initial comments on this article before reading the rest of these comments. I sensed something in the original article that made me feel like builders "should be" excluded from this conversation, but I couldn't put my finger on it. After reading the above comments from the author, I understand where my concern came from. I don't believe that this industry (design, construction, operation of buildings) can create true efficiencies and improvements without working together. Builders, as well as designers, subcontractors, suppliers, engineers, facilities management, etc. DO KNOW what you are talking about and are move forward with discussing integrating around a central 'taxonomy'.

I really bristled at reading this comment from the author of the article and almost completely lost track of the idea of the article (taxonomy):

I’d also have to say that it has become fashionable for old General Contractors to grab the reigns but they know nothing about what we are talking about. For me Construction Management should lie within the Architectural Domain.

Ouch.

Final Issue of 'Cool Architects'

2010-01-29T20:49:00.002-05:00

Thank you to all of the architects who worked with us on this, and the previous issues of Tocci Today 'Cool Architects' - so amazing.

This issue features two of the presenters from the last BIMForum, Morris Architects and Gensler along with two local firms using BIM in interesting ways.

More from the BIMForum

2010-01-25T16:37:00.005-05:00

If I keep putting off blogging about the rest of the BIMForum meeting long enough, I won't have to do anything except post links.

Here is Vela's take on it, interesting thoughts...

BPM: Building Prettiness Model

2010-01-18T19:19:00.001-05:00

I am waiting for images from Christof Spierler's presentation before I post all my notes, but it was a great presentation that kicked off the BIMForum with energy. In it, he coined a new acronym 'Building Prettiness Model', described in further detail here.

BIM Claims

2010-01-18T15:42:00.005-05:00

One of the most interesting presentations at the BIMForum was Gregg Bundschuh's (of Ames & Gough) presentation on "BIM Claims and Insurance Cover: A Survey of Recent Developments".

According to Gregg's presentation, there have been about 30 claims arisen from BIM utilization to date. The claims group into about 6 categories and generally relate to delay and cost overrun claims:

2D -> 3D Conversion Where the contractor performs a 2D conversion and makes an assumption about design intent in the conversion process
Versioning When firms "mix and match" versions of the same software, inconsistencies result between models of different versions.
Default Settings When firms use the default settings of software, errors can occur.
Model Reliance No surprise here; this issue is the most prevalent and occurs when someone over-relies on a model.
Interoperability Three claims have come about when conflicts occur between design and fabrication models; although, those were mostly in structural steel.
Standard of Care The most interesting claim by far comes from an arbitration that was resolved about 2 months ago, in the midwest. The design professionals only created 2D documents (per their contract requirements). After the contractor did a 2D conversion, they published clashes to the architect, who "ignored them". The architect's argument was that they weren't paid to go above the standard of care. However, the arbitrator said that the architect should have resolved the issues, once advised. It was determined that the architect did not meet standard of care and the contractor was awarded several million dollars. (By the way, I don't claim to have gotten all details correct here..just the jist of things.)

The implications for changing the definition of Standard of Care is quite interesting. As Gregg said, "when the Standard of Care changes, it is more of a rear-view thing, but when it does change, where on the road do you want to be?"

MEP Modeling

2010-01-15T11:18:00.007-05:00

Mark Mergenschroer, from TME Inc, presented yesterday morning on the "current state of MEP Modeling for Engineers". He described the current state simply: behind. (Although TME is fairly advanced.)

In preparation for his presentation he reached out to his counterparts across the country to see what they are saying about transitioning to BIM.

"It's too expensive." Mark's response: Yes, software and training can be costly. But there is value. BIM has kept them busy in the slow economy because architects want to work with BIM-enabled engineers. They haven't had to cut any people and had a very profitable year last year.

"There isn't enough MEP-specific BIM training available." Mark's response: That may be true, but it's not an excuse. You can get general training and then think outside the box to apply it to your workflow.

"There isn't enough MEP content." Mark's response: Make your own. There isn't enough of ANY content out there.

"There is so much that you can't do with BIM." Mark's response: So use BIM for what it can do, rather than complaining about what it can't. You can contort many software programs to get done what you need to get done. And most programs are advancing.

In short - no excuses.

State of the Art: Holding Tolerances

2010-01-14T01:26:00.006-05:00

After Tri-City, we ended up at Kovach to see their prefabricated specialty exterior wall panels. We spent most of the time discussing their process, which is based around laser scanning the erected and framed building.

Before Kovach adopted their BIM-enabled process, they would have to hand-measure an entire building before fabricating panels. One past project required 7000 panels - 650 unique size/color combinations. About 600 of those panels had be remade due to fit problems. The problem is the tolerance of their panel is tighter than the tolerance of prior trades.

Since adopting their new workflow (which I will describe in just a second), they have completed 10 full projects. On those projects, they lost zero panels to fit problems (a few panels were lost due to damage) and have seen zero punch list issues on several of those projects. A 2-man crew is able to place 85 panels/day (compared to 10/day previously). They aren't to the point where they have figured out the exact dollar savings, but are compiling data so that they can consistently reduce pricing.

Okay, so their process.

Rather than hand-measure the building, Kovach laser scans the exterior. The point cloud data is converted to a wire frame model representing the as-built conditions. From there, they model and layout the panels and required substrates. The information is exported to CNC, as well as to a set of 2D panel maps - all dimensioned to the nearest 1/1000". (Why..because they can)

These were the kind of metrics I wanted to hear and a very unique process. The CNC part of the process was almost irrelevant (although of course, it wasn't). The concept of using laser scanning to document as-built conditions is certainly out there, but I haven't seen a subcontractor (or anyone, really) transform their process with it so significantly.

State of the Art: Mechanical In-Sourcing

2010-01-14T01:01:00.004-05:00

After Schuff, we moved on to Tri-City Mechanical who has an interesting relationship with Omni-Duct Systems. I'm not sure how long ago, but Tri-City is partnered with Omni-Duct, who does the prefabrication of ductwork. Tri-City used to do their own, but they could only process 75 lb/hour. Since Omni-Duct can achieve 130 lb/hour, Tri-City can offer a competitive advantage by using Omni-Duct - who is located in the same building as Tri-City. (I found this especially interesting because I just reread Tom Friedman's World is Flat for my 'Managing Collaborative Relationship class. In this he talks about one of the major 'flattening' strategies, insourcing.)

Tri-City spent some time reviewing their 8 step process (from modeling to installation). Although their process was very interesting (especially automatic nesting, where pieces are placed on sheet metal in a way that minimizes waste), one of the best parts of the came up during the Q&A.

We started discussing the workflow from engineering to fabrication, and John Tocci asked the presenter what he would do with magic fairy dust, that could change the engineering process in any way they wanted. Tri-City wants to have their tradesman sitting next to the engineers, as they are design and laying out the systems. Ideally, the engineer would work in CAD-Duct (their vertically integrated software used for just about everything), but to make that valuable, they would have to use Tri-City's database and bring them on early enough.

This of course, forced the question - what is the competitive advantage to bringing subcontractors on board early? Although I agree that there is value to bringing subcontractors on early, we need to prove to owners that they aren't losing the perceived competition of hard bidding. Tri-City said that this was the case, but couldn't supply metrics of any sort.

Which leads quite nicely into our next and final stop: Kovach.

State of the Art: Steel Fabrication

2010-01-14T00:35:00.007-05:00

Today was a BIMForum first. We added an optional day to the conference, went off-site with 60 attendees and saw a few of the workflows that we've been discussing for the past few year. The first that my group visited was Schuff Steel's 1/2 mile long fabrication facility.

Because there was so much to see on the "shop floor", we didn't spend a lot of time discussing Schuff's model requirements and up front process. However, Chris Fischer explained that their detail group models in Tekla, no matter the data source (which still ranges from pencil drawings to Revit models).

The data in Schuff's Tekla models feeds into their full range of CNC machines - everything from the plasma cutters to the robotic welder. CNC is so much more efficient than traditional fabrication methods that Schuff puts in additional effort to use it - there is a 50" length requirement for CNC, so when Schuff has to fabricate smaller pieces they actually stitch them together to leverage the efficiency.

Schuff has built automated processes into their workflow to gain efficiencies and avoid downtime - a sensor is built into the feeder wire. When the spool runs low, an email is sent to the shop manager and the supplier, so that it is replaced before the welding machine runs out.

We ended the tour with an opportunity to really visualize the connection between the model and the fabrication process:

Next stop: Tri-City Mechanical

Filling Out the Team

2010-01-13T07:42:00.002-05:00

We are looking for team members to join what we are now referring to as our 'World Series championship' VDC team. I have posted the two position descriptions here and here, on
our website, but here are a few key points about the positions:

Currently there are two positions available - one VDC Modeler and one Coordinator; however, we anticipate hiring two additional modelers once we have filled the other positions.
The Coordinator needs MEP experience, to take our coordination, optimization and prefabrication processes to the next level.
We'd love for the VDC Modeler to be a Registered Architect or PE.
All positions require the emotional engagement with Tocci and its projects. That means an understanding that you are working on something bigger that yourself and the willingness to dedicate yourself to it.

Send resumes to me.

Coordination Requirements

2010-01-12T10:16:00.003-05:00

Wow, am I so behind the times that I didn't even notice when the BIMForum website published the MEP Requirements...that I contributed to!?

Apparently.

It's a great starting point for MEP coordination for any project - and helpful for designers and builders alike! (How good am I at advertising this..)

Next Gen of Model Navigation

2010-01-06T09:31:00.003-05:00

I really want something like "location-based model navigation", to use on site, but this is pretty cool too.

Houston, thanks for sending me your post.

BIMForum Next Week!

2010-01-05T10:19:00.003-05:00

I can't believe that the BIMForum is next week - in my mind, we were just in Philadelphia. I'm really excited about this meeting because we're starting a day early (optionally) to tour BIM-enabled prefabrication facilities of several subcontractors, local to Phoenix. Although we are noticing a few more BIM-enabled subcontractors in New England, there are so many more sophisticated firms in Phoenix.

I think the actual meeting content will be excellent as well - practical, good presenters sharing lessons learned and best practices.

If you aren't registered yet, there are a few open spots left...and plane tickets are still fairly reasonable. Presentations won't be available to those who don't attend, so if you can swing it, you should. I'll try to take good notes for everyone, but you all know how that goes!

Digital Mock-Up: Window Detail

2009-11-23T14:19:00.003-05:00

Lately, we've been using digital mock-ups more and more. Here is an example of one at a window detail:

Commentary on You're the Boss

2009-11-20T08:56:00.014-05:00

One of the many non-BIM blogs that I read/skim is "You're the Boss", a NY Times blog about running a small business. Specifically, the author, Bruce Buschel, is starting a restaurant, which I have found fascinating.

Yesterday, he wrote a post about the progress of construction on his new restaurant and had a few interesting things to say, which I think reflect the state of our industry. The overall theme of his post is truly about planning and expresses the need for the transformation we are working to make, through VDC. A few great quotes:

"...So the plumber is at work, playing Twister with the HVAC guy as the electricians dance around the carpenters..."

"...There are drawings upon drawings, and then changes upon changes upon those drawings. Everywhere you look, rubber bands contain the drawings, 24 inches by 35 inches, rolled up like parchment-paper communiqués between Jefferson and Adams..."

Buschel is impressed with the ability of architects to visualize and understand design using 2D plans, because he has no ability to do so - like so many other people in the industry. Only as he stands in the partially completed space, he starts to see "this materialization of a thousand decisions made so long ago in the abstract".

I think this is a struggle for so many, who cannot visualize the end space. Once they finally see it,

I would have loved to show Buschel a BIM of his project, sometime during design. As a contractor, we suffer from indecision, late decision, or change of mind. All three are costly and time-consuming, and as Buschel points out, test the paitence of the team. We don't like to see owners struggle to make decisions, and honestly, much of the indecision comes from lack of information. What do the options look like? Cost? What is their impact of schedule?

VDC clearly cannot solve all of these issues, but can help good teams extract and position information to move forward with design and construction.

The Platinum Issue

2009-11-19T08:29:00.005-05:00

The Platinum Issue of Tocci Today came out today. This one focuses on the final outcomes of the Autodesk HQ:

No Pipe Slope?

2009-11-16T11:03:00.005-05:00

Jeremy, one of Tocic's VDC Modelers brought this to my attention this morning. We played with it for a little bit, but couldn't figure it out. I obviously forwarded the issue to Autodesk, but figured I should share with all of you - in the event that we are missing something simple (or there is a less than simple fix!).

The Goal: Slope pipe: 1/4" every 10'

Usually to slope, we just select the entire area that needs to slope and type the required slope. Works like a charm - locating each fitting and pipe at the correct elevation. We did the same thing in this case, but apparently, it is too small of a slope for Revit. Geometry didn't change; slope on pipe reads 0"/12".

No, this slope isn't huge, but the main runs 200', which is a change in elevation of 5". That clearly will affect coordination.

We found a workaround, but it isn't realistic to do this on the entire system, so we've decided just to do it on the main (which has about 5 bends in X/Y). If you change the elevation of one end of the pipe to the manually calculated value, it will slope it (although the elevation still reads 0"/12"). So for each bend on the main, we have to calculate the elevation based on the slope and manually type. (I hope the layout doesn't change too much!) We have decided to ignore the slope on branch lines for now, which run about 50' - only because we don't have to have to do so much work if things change.

This really shouldn't be a problem. Are we missing something or can Revit really not recognize slopes below a certain amount? Is there a better workaround?

Structural Workflow - Semi-Social BIM

2009-11-10T08:43:00.005-05:00

LA Fuess, who hosted the BRUG meeting, also presented on one of their projects.

On this project they were only design team member to work utilize VDC (although now they are working with Revit-enabled architects on about 20% of their projects). The contractor, a JV between Austin and Walsh, utilizes BIM, but initially wasn't sure if they could trust the accuracy of LA Fuess' model.

In the end, LA Fuess proved that their model was accurate and detailed enough for use in coordination and fabrication-assistance. They actually added geometry (like gusset plates) at the request of the contractor (a lesson to all of us: ask and you shall receive).

The model was transfered to the fabricator for detailing, and the information was so beneficial to the fabricator that it cut down the detailing schedule by 2 months.

Structural Workflow - Modeling Wood Framing

2009-11-09T14:29:00.004-05:00

Another presentation at the BRUG meeting was a wood frame project from SGH. The building is an existing church, originally constructed in 1955. A fire destroyed much of the roof and second floor, so SGH is working on the new structure.

I was really impressed with the level of modeling that SGH did - every stud, framing, etc. I know from first hand experience that wood frame modeling is somewhat painful. Some of the issues that were brought up related to the documentation of the information after it had been modeled (tagging, line weights, etc.), but we definiately ran into some of the modeling issues - there aren't a lot of families and everything has to be modeled manually.

Hopefully life will improve with either the 2010 enhancement tool or the latest version of MWF (which I've heard is quite nice!).

Structural Workflow - Revit to ASD

2009-11-09T13:16:00.020-05:00

Last week's BRUG meeting focused on structural workflow, from design to fabrication. One of the three presenters was Derek Gilbert, a Technical Specialists from Microdesk, who presented on Revit Structure and AutoCAD Structural Detailing (ASD). ASD comes with the Revit Structure Suite.

It looks like Revit exports direct to ASD and then users can use detailing macros to add connections, piece marks and create shops. I don't believe there is a bi-directional workflow, but it seemed like updates can be sent from Revit to ASD.

I noticed a "formwork" button, but Derk told me that functionality is not quite ready. Hopefully soon, as we have a massive CIP project we are starting! We have been looking at Tekla for this and more, so it will be interesting to compare the two platforms. Although functionality is key, we're also interested in going with the product that most fabricators use. Collaboration is a huge driver of our software decisions.

BIMForum Webinar on Laser Scanning

2009-11-04T15:38:00.002-05:00

This was set up so last minute, that I didn't even have time to blast the link for sign-up. I will make sure I do it for next's month - which will be the ConsensusDocs BIM Addendum.

Here are my notes/thoughts on the webinar (copied from the Q5 blog..do you really expect me to write a unique post?)

Today, the BIMForum Constructor’s Subforum held its first monthly webinar, discussing laser scanning. The BIMForum decided to tackle this topic because, in the words of Pat Carmichael from HKS, it enables a “level of detail of built analysis that you can’t effectively get any other way”. Pat gave the architectural perspective on laser scanning. He walked through several of HKS’ use cases, mostly stadium projects, and addressed the value that they get from the process.

Mario Mazzi, from one of Turner Construction’s West Coast offices, outlined their process for planning laser scanning. It is similar to one that we would recommend, so we added some Q5 advice in context:

Step 1: Plan

Determine the end use for the laser scan data. Do you want to coordinate new design with existing conditions, compare as-built conditions with as-designed data or something else entirely? Will you convert to BIM or use in native point cloud format?

Step 2: How to Collect?

You basically have three options: subcontract the laser scanning, rent a laser scanner or purchase your own. Some general criteria:

If you have over 6 months of laser scanning to do, buy. Why? Because laser scanners cost $120K to purchase and $20K/month to rent.

So how do you decide if you want to subcontract or rent? It really depends on your organization and your project. Do you have surveying capabilities in-house? Can you dedicate a team to laser scanning? Do you want to train staff in data collection or modeling? How large is the space? What type of scanner will you need? Since many projects require multiple types (for close-up and distance), it may not be cost effective to rent.

Step 3: What to Collect/Model?

Determine your level of detail. What objects do you really need to capture or model? Although a laser scanner will capture everything in “line of sight”, you may not need to convert everything to Building Information Model format.

Step 4: Map Your Schedule

Create a schedule that includes time to capture data, which may be based on when you can access the space. Map out how and when data will be sent, and if data will be sent intermittently or only when complete.

Surveyor Navis Plug-In

2009-11-04T13:54:00.003-05:00

One of the limitations of Navisworks relates to quantities and exports. I think we can use the API to aggregate quantities, but my programming skills and resources are next to nothing, so it is still a limitation to me!

Until now....? I just got a marketing email for Navisworks Surveyor, a plug-in that organizes exports from Navisworks based on Search Sets. I could see this being very helpful, as we use Search Sets ad nauseum to organize our models. Once we set up a file, we could extract quantities directly from the Search Set, making it easier for the cost engineer to understand "what the quantities are coming from". (Although, yes, they could do this with QTO, too.)

This could definiately expand our supers' capabilities. If they need quantities for ordering, they can just extract them!
This looks pretty interesting, even though the interface is a little tough looking. And until December 31, they have a BOGO sale for Navisworks customers. I'm still digging into it, though. Is anyone using this?

Correction

2009-11-03T13:48:00.002-05:00

Correction on this.

I would have been so excited about batch processing, if Revit files were included. (Unless I missed something..and I really hope I did).

VDC ROI, the Subcontractor Perspective

2009-11-02T09:06:00.003-05:00

I've talked about the owner perspective and contractor perspective; now, here's the subcontractor perspective.

JC Cannistraro focuses on the ROI of VDC in their Fall 2009 newsletter. The summary: the more they utilize BIMs, the more they reduce change orders. Furthermore, social BIM reduces change orders even more.

Makes sense, but the ROI needs to be pushed to the next level. What about the ability to reduce schedule and budget (baseline budget, not change orders)?

View Range

2009-11-02T08:36:00.003-05:00

Someone has finally managed to simply explain "View Range"! View Range is one of those things that I always struggle with. Hopefully now, I won't.

We use DesignReform's tutorials a lot for training, so I'm happy to add this one in! Thanks David - now you just need to explain View Range for RCP.

Navis Subscription Package

2009-10-22T17:41:00.001-05:00

Rather than actually detail them myself, I'll defer to David.

So excited about batch processing..

Platinum

2009-10-22T10:20:00.002-05:00

The final review for Autodesk HQ is complete and we earned LEED-CI Platinum certification with 46 points! Our final IPD goal achieved!

Revit 2010 Enhancement

2009-10-20T13:57:00.007-05:00

I just got off the webinar Autodesk put together for a few bloggers on the Revit Platform 2010 Subscription Advantage release of Revit (coming...soon). Others have already posted some information (like the new interface for keyboard shortcut management), but there are a few things I'd like to highlight:

Revit Architectural will now have a wood framing extension tool, for walls only. My team is really excited about that, but after trying out MWF and others and finding that it was hard to manipulate, we are trying to temper our expectations.

As someone pointed out during the demo, the extension missed a few studs when framing (hard to see in screenshot):

This feature seems like it is the largest major upgrade. There are a lot of other small upgrades and additions that we're mentioned like conditional formatting in schedules, conversion of models lines to and from detail lines (this may be major for A/Es, but isn't for us), more structural capabilities in architecture (trusses, curved beams, beam coping tool - see image below - and decking improvements). The major MEP improvement seems like performance; although, they aren't allowing us to "turn off" calculations while doing layout.

Another nice thing is that subscription users will recieved Image Modeler, which enables conersion of images to DWG models. It is a nice existing condition modeling tool, which we are in the process of testing, but isn't really a replacement for laser scanning, with regard to accuracy. We are also looking at a similar competing product, PhotoModeler.

Another extension that we will have access to is Revit Model Review, the product acquired from Avatech. We played with that for a while, but never found a practical way to use it on projects. Maybe now that we have it with Revit, we will...

Overall, I'm looking forward to the upgrades and definiately enjoyed the preview. Thanks David and others for coordinating and presenting...

"Field BIM"

2009-10-19T16:19:00.004-05:00

Although I don't always agree with the Vela-specific branding of the term "Field BIM", there are some pretty amazing things being done with linking Vela to Navis or Tekla for material tracking, punchlist, etc. Here is an update on a doors/frames/hardware workflow from Vela and DPR. (You will need to click on each JPG to read/print because I was too lazy to deal with PDF upload...or is there an easy way to do this in Blogger?)

IPD Without BIM...

2009-10-19T07:20:00.002-05:00

At a meeting on Friday, we (meaning KlingStubbins, Tocci & Autodesk) were discussing concepts of IPD and BIM. In his definitions of BIM and IPD, Phil Bernstein seperated the two concepts: BIM is a technology-enabled process; IPD is a contract. He acknowledged that it is very difficult to disentangle the concepts, as it is hard to imagine doing IPD without BIM:

As he said, "I guess you can do heart surgery with an exacto knife, but I think there are better tools available."

Manufacturer Content - Part 2

The family is beautiful. Accurate geometry that flexes. Not too much detail, but enough.

One family for entire line of products, with types set up for various sizes.

One small issue that prevents us from implementing the family as is...it's ceiling hosted. And ceiling hosted families are constrained to the finish face of the ceiling, so we can't even find a workaround.

Is there a way to change this family to a unhosted family? Easily? I tried copying the geometry over, but obviously lost a lot of the data and constraints. And then I couldn't even load it into a project - I got a very generic error. Help...

Manufacturer Content

2009-10-14T10:02:00.012-05:00

So we have a submittal deadline Friday for New Street. And we (Tocci's VDC department) are responsible for some of the drawings that will be included in the submittal set - specifically HVAC and plumbing. (As described here, modular has a different submittal and approval process).

Four days away from the deadline (so yesterday), the team decided to change the heat pump to a Mitsubishi instead of a Daikin. So we are in the middle of a "quick" update and remodel.

We have a cut sheet for the unit, but before I started modifying a family to reflect the Mitsubishi characteristics and dimensions, I called them to ask about any additional product data. In the conversation, he asked what I was doing with the information, what project, etc. - and it came out that I needed to model it in Revit.

As it turns out, he sits next to the guy who models all of the Mitsubishi units in Revit, so he's going to email it to me. This was all about 10 minutes ago, so I'm still waiting for the email. Fingers crossed for a good family..

Modular Construction & BIM

2009-10-02T15:45:00.002-05:00

This month, Tocci Today featured modular construction and a recently awarded modular project. In one of the articles (the KBS Building Systems one), we outlined the process we are using to coordinate, document and fabricate the modules. As we move forward in that, I'll share more details..!

Electrical Room Layout

2009-09-24T10:35:00.006-05:00

This morning, we received an electrical room layout for coordination - nothing terribly exciting in that, except....that we received it from our electrical subcontractor in Revit!

Hollywood BIM

2009-09-24T08:15:00.003-05:00

Lately, we have started talking about Hollywood BIM - you know, BIM that looks really nice or that is used to win a job, but functionally doesn't help the project or process at all. For example, a beautifully rendered logistics plan, showing cranes whirling around in circles - that the super and subs never see or use.

The latest AECbytes viewpoint article discusses this is some respect; their focus is actually on moving past the "BIM hype" into real, transformative BIM that addresses business issues.

The next you see some "really nice BIM", make sure you look behind the curtain to see if its real or Hollywood.

RevUp Rendering

2009-09-14T11:01:00.004-05:00

A few weeks ago, I received an email from Ry Bruscoe, the Principal Founder of IDS. His latest venture is RevUp Rendering, a company that

"provides access to an advanced SuperComputer to use to run Revit from anywhere in the world."

So basically a remote desktop connection to an awesome computer, right? I think I'm intrigued, but really have no opinion until I check in with my hardware guru. JTJ?

Not Exactly BIM-Related...

And news feed.

RFIs and Submittals

2009-08-28T16:41:00.005-05:00

I find it interesting that many projects report number of RFIs, as if fewer RFIs equate a more successful project. It is equally interesting that eliminating submittals is a goal of many projects. While I understand that there is waste inherent in traditional submittal and RFI processes, I don't know that either should be thrown away. They exist for reasons outside litigation.

Earlier this week, where someone compared the submittal process to active listening.When a subcontractor creates shop drawings, they are really paraphrasing to the design team, "This is what I think you just said. Is that correct?"

At the same time, if an RFI asks an intelligent question, and perhaps suggests a solutions, is there really a problem?

I understand the position CYA behavior..and certainly agree that all processes can be improved (i.e. think of the time that paperless submittals create). But before we throw away our old processes for new, I don't think we should forget their purpose.

BIM-Enabled Prefabrication

2009-08-26T10:45:00.003-05:00

J.C. Cannistraro, who worked on the Autodesk project, describes their process:

Texas #2?

2009-08-18T15:27:00.003-05:00

Almost a week ago, the Texas Facilities Commission announced their adoption of Building Information Modeling, with standardized requirements (BIM Specifications) coming out in the near future. It will be exciting to see what the TFC requires with BIM and which states follow.

Virtual Tour of PCX

2009-07-31T09:20:00.008-05:00

Yesterday, I attended a project kickoff meeting for a Crate&Barrel in Toronto (actually Mississauga, but apparently it's close enough to refer to it as Toronto). Represented as this meeting were the design team (A/S/MEP), builder, early engagement subcontractors (MEPFP, thin-brick panels, prefab wall panels) and suppliers (Trane & PCX). PCX is providing the pre-manufactured EDC:

They use Inventor to model their units, which is nice - the model can be imported into Revit for coordination; although it alone is 4.86 MB due to the detail.

They also provide a virtual tour of the box before it is shipped. And here it is installed.

Surprising

2009-07-14T22:12:00.003-05:00

I know that I've heard many times that most people still use AutoCAD, but I was still surprised by this.

Really? Additionally, so many people use it (and plan to use it) that they come to AU for AutoCAD classes? I cannot even fathom this.

Wisconsin

2009-07-10T13:34:00.003-05:00

I'm a few weeks behind on writing about this...although I managed to send an internal email about it earlier.

So the headline (I opted to ignore all comments on this article) is that Wisconsin (specifically the Division of State Facilities) is requiring BIM! In actuality, it is requiring A/E BIM on projects budgeted over $5M (or something like that).

This is definitely a step in the right direction, but it's only the first step (which the state recognizes). Even for "design BIM", they will definitely need to expand and detail their standards. And of course, until they address requirements for builders, they aren't getting the true value.

In any case, it is interesting to review their standards, especially the modifications to the compenstation schedule to reflect the MacLeamy Curve.

ROI at BIMForum Dallas

2009-06-16T07:46:00.008-05:00

The BIMForum's most recent meeting was a few weeks ago in Dallas and focused on the value of BIM from 30 day to 30 years. Needless to say, there was quite a bit of talk of ROI (including a panel I moderated on Friday), but the presentation that is getting the most buzz is John Moebes' presentation on ROI from an Owner's perspective. He titled his presentation: "ROI for BIM: What One Cranky Owner Would Like to See".

A quick summary: he doesn't want to hear marketing or talk of "BIM use" unless it is having a dramatically profound influence on fees, schedule or construction costs. He doesn't want firms to proudly submit savings from clashes found. He doesn't think that less bad is good enough. (Which is true; although, less bad is better than worse...) As he said: "Owners don't pay for clashes, they pay for a properly coordinated model." (I take some exception here; owners don't pay for a properly coordinate model; they pay for a properly coordinated end product.)

He has provoked a lot of discussion (for instance here and here) - both negative and positive reactions abound (although the BD+C article seems to be drawing more of the negative). Initially, I found his presentation difficult to listen to (after all - Tocci is building a Crate and Q5 is consulting on several others!), but upon reflection I completely agree with what he is saying. Our industry needs to stop congratulating ourself for "doing BIM" (why do people even say that?) and start actually utilizing Virtual Design & Construction to improve projects.

I commend John for saying what need to be said, even though it may be hard to hear.

Q5

2009-06-05T14:14:00.006-05:00

I have been somewhat absent for the past month because I've been pre-occupied with an exciting project: launching Q5, an affiliate of Tocci. Q5 provides VDC Services and IPD Facilitation.

Q5 has (and will) given me an opportunity to work on projects from a different standpoint and do different work for some of our same clients:

- Develop RFPs for owners, designers and contractors and assist with BIM-enabled selection
- Set up corporate-wide VDC standards and processes for national developers and owners
- Facilitate "social BIM" between architect and many design consultants during design
- Review quality models for designers and owners - to make sure that they're getting what they were promised...

Since the same team will be working for Q5 and Tocci's VDC department, we will be switching back and forth between projects, which I was concerned about at first (from a workload standpoint) but now I'm really excited. By working on Tocci projects, we will apply a sense of accountability for actual exectution to Q5 projects (something we think is lacking in the generic VDC consulting world). And by working on Q5 projects, we will be exposed to the other perspectives in the industry in an IPD-like fashion; applying that new knowledge to Tocci projects wouldn't be a bad thing!

Site Signage

2009-04-27T10:27:00.003-05:00

A few months ago, Tocci worked with Crate&Barrel to produce temporary mall signage Crate we are building in Natick MA. Our graphic designer played with a few different ideas, but in the end, opted to leverage the model for yet another use - she wrote about it here.

Since she wrote that piece, the signage has been placed. And it looks amazing - I love seeing Crate model images in "real" scale!

Speaking of EMCOR/Dynaelectric..

2009-04-22T16:26:00.001-05:00

Jim Bratton sent out this article on how they've adopting Virtual Construction, that specifically speaks about their efforts as an electrical contractor. Very interesting.

Enjoy.

Inventor LT AEC Exchange

2009-04-22T10:05:00.002-05:00

I was talking to Jim Bratton, from Dyna Electric, yesterday and he mentioned that he was looking at Inventor LT to produce product models that could be used in both AutoCAD MEP and Revit MEP - because of the AEC Exchange. The AEC Exchange is described as follows on the Inventor LT page:

Enhance service to your customers by providing 3D models ready for use in their building designs. The AEC Exchange tool creates and publishes simplified 3D representations, intelligent connection points, and additional information in the new ADSK (Autodesk Exchange File) format for use with AutoCAD® MEP, AutoCAD® Architecture, and Revit® software.

Does this mean that AutoCAD MEP and Revit MEP may one day be on speaking terms?

My Take on Navisworks 2010

2009-03-26T10:11:00.015-05:00

I just read through Volker's post on Navis 2010 and found it very informative, but of course, I have comments of my own! I enjoyed particpiating in the 2010 beta, and was thrilled to see some of my requests come to fruition (probably because everyone else was requesting them too!).

The updates to the interface (ViewCube & Steering Wheel) are helpful. Although I initially hated ViewCube, I really like it now and am happy to see it in Navisworks (and I love that we can actually turn it off, too!).

And yes, as Volker mentioned, there are improvements to the measure tool, sectioning and visualization (finally - a horizon in Navisworks).

But I think that the most important improvements weren't included (or weren't covered in great enough detail) there.

First and foremost, shared coordinates are finally recognized from Revit. So now, we don't have to worry about 'Override Transform' just because someone set up the various models out of allignment. I see this fix as a huge benefit to collaboration. Often times, we have no control over where other parties place their model (in reference to 0,0,0). (The next step will be to recognize 'New UCS' in the AutoCAD export, right Richard?)

Yes, viewpoints are exported from Revit, but graphic overrides aren't maintained. We're a little frustrated with that.

The improvements to clash detection are really exciting. Clash reports are normally so cumbersome, with hundreds or thousands of clashes in a list. The ability to organize things by folders is helpful; the automated "group clases involving item" is even better. New graphic abilities in clash detection are really helpful: the animated transition from clash to clash, the ability to view a clash in context and the transparent dimming will be really helpful during coordination meetings. Oh, and we appreciate the additional clash status of "reviewed", but why can't we make custom statuses?

We love this release - in fact, we've already upgraded to it (still using beta of course) for current projects because the new features are worth it.

Modeling for FM

2009-03-26T08:36:00.011-05:00

We haven't seen a lot of demand for facilities management models from owners. Despite that, we're trying to push baby steps. Some contractors have developed far more sophisticated FM deliverables - Holder specifically comes to mind. Since the demand is low, we are taking very simple approaches, just to demonstrate to owners just a little bit of the value. One example uses hyperlinks to cut sheets for specific components and views of areas.
We implemented this concept for a hotel project - aloft, a new brand for Starwood. We created what we refer to a 'maintenance documents' (we have to make up a name for everything, right?).

We also included walk-throughs of each unit on a CD, with the walls set to transparent. This has enabled maintenance staff to understand the exact location of system components, without having to learn any software.

Very simple, but for this situation, it made sense. And hopefully, we'll have an opportunity to implement a more comprehensive solution for an owner who really wants it.

ROI of VDC

2009-03-26T08:20:00.012-05:00

Ken Stowe (Autodesk) organized and moderated a session at AU last year on ROI of Utilizing BIMs for Builders. Builders from several companies shared how they are using BIMs, some of the challenges they've encountered, the benefits, and then some metrics associated with that use. The information was great, so the company has been watching the recording of it. It has gotten me thinking about our own metrics.
With regard to our VDC adoption, we are in an interesting place right now. We are wrapping up our involvement in our first VDC projects (Gen I & Gen II projects) while we are working Gen III projects, all of which include a model sharing component and several of which contractually require virtual construction. It almost hurts to look at earlier projects - we are more efficient now and the tools have come so far in just 2 (almost 3!) years.
There is one exciting thing about wrapping up these Gen I & II projects - we finalize our ROI for VDC on the project (and then with much fanfare, we present to John Tocci, other Tocci execs and the project owner).
Calculating ROI is difficult and is definitely up for interpretation. Our take on it: document everything we used the BIM for on the project (in a ridiculous spreadsheet that includes 20 different tabs, hyperlinks and formulas that I always manage to 'break' - although I always fix them before the VC Coordinator on the project notices) and then figure out what would have happened if we hadn't used the model for that (working with subcontractors, supers, etc.).
Here are two examples from one of our projects - you'll probably have to click on the image to actually read the text (I couldn't get it any larger and was too lazy to retype):

From there, we add up the totals and do a little math to figure out total ROI; for the project referenced above, it turned out to be:

Of course, anyone can come in and say that issues could have/would have been found without VDC, but it does give us a sense of what VDC has contributed project. And at least it starts the discussion. How is everyone else calculating VDC? Any comments/criticism on the examples I shared? Any feedback is great, as we want keep improving as much as possible.

Steel Fab

2009-03-26T08:10:00.009-05:00

A while ago, several of us (myself, PM & APM) went to SteelFab's facility in Charlotte, NC for a meeting with the owner's rep, architect, engineer, steel fabricator and detailer for the Crate&Barrel project. We all met there to review outstanding issues regarding steel, so that we could release it for fabrication. In the morning, we reviewed those issues, using both drawings & model (the design team is all Revit; the fabricator is using Tekla).
After that, we were able to tour SteelFab's fabrication facility. Since they use Tekla, they are able to take advantage of a model direct to CNC workflow for fabrication. We've heard a lot about this workflow, but it was very informative to see it in action, along with their coding system, to keep track of each piece of steel for a project.

And we are finally able to leverage data from the design model by sharing it with the fabricator (I didn't feel like finding all the images; I just grabbed the marketing-esque images from our PPT).

IPD at Trapelo Road

2009-03-19T08:24:00.013-05:00

I always feel odd posting things like this, but I guess I've gotten over it.

Autodesk, KlingStubbins and Tocci didn't just integrate for design/construction; we have also integrated on PR for the project. (It's amazing that even after Autodesk has occupied the space, we're still all speaking, respecting each other and having fun, huh?)

I refer to one of the pieces as "The Autodesk Movie" and it was recently upload to youtube for everyone's enjoyment (although I always feel uncomfortable watching it....).

Boston Revit Users Group

2009-02-24T16:11:00.002-05:00

Whenever I see other blogs referencing Revit Users Group, I am jealous. Partially because I don't live in same geographic location, so I can't attend. And partially because there isn't an active Revit Users Group in Boston....until now!

If you are in the area (or not, I suppose!), please join the Boston Revit Users Group: http://www.meetup.com/Boston-Revit-Users-Group/

Our next meeting is on March 26, and will preview Revit 2010, from Autodesk (with NDA of course), at their new HQ in Waltham (and yes, they have occupied the building!).

My Pet Peeve

2009-02-02T09:43:00.001-05:00

Originally, when I thought about writing this post, I was going to link to a number of reputable sites that break this rule. Then I thought about it again, and decided to give these organizations a chance to clean up their act.

The offense? BIM model. If you are wondering what is wrong with saying BIM model, you too are guilty. Think about it: Building Information Model Model? Hopefully, this will teach you your lesson, and you can spread the word to the rest of the industry. What are you supposed to say when referring to your group of Revit (or equal) files that comprise a Building Information Model? Just try saying BIM, or the BIM, or even the model.

As for the organizations I referred to above, I will compromise: click!

Belated Holiday Card

2009-01-28T08:33:00.003-05:00

This year, Tocci sent out an e-card. I meant to post it, but then I forgot. Oops. Better late than never... In any case, we've had a lot of feedback, including Mark Sawyer's thoughts on it, which we truly appreciate.

Next BIMForum Meeting

2009-01-10T09:52:00.006-05:00

The meeting will be on May 28th & 29th in Dallas at the Omni Mandalay. Registration isn't open yet, but please save the date.

The theme of the meeting or topic that we will be digging into is "BIM: Now, More Than Ever". In our discussions about this theme, we have discussed presentations, workshops and working sessions related to practice "how-tos" for company implementation, how to speed up payback, and additional services to offer because of your use of BIM. We will also discuss both the need and strategies to educate PMs, PAs and mid- and high-level employees.

So save the date, and look for an email from BIMForum for registration.

Cleaning Up on Site

2009-01-10T09:40:00.003-05:00

One of the features of “full” IPD contracts is that project participants (who are involved in the IPD team) bill “at cost”. For us, this includes architecture, design MEP, CM, MEP/FP subcontractors and drywall. This creates an interesting dynamic on site – where the most appropriate and cost efficient participant performs work that may not traditionally be considered in their scope. This forces all to focus on optimizing the whole. This includes tasks from layout to using lifts/equipment to cleaning up on site.

Traditionally, we require our subcontractors to clean up on site. However, in this case, we didn’t want a trained specialty contractor spending time cleaning up on site when we could have a Tocci laborer do the same work at a reduced hourly rate. So, we “bought back” that typical scope component and are adding to the project savings for everyone by spending less.

BIM for Electrical

2009-01-10T09:34:00.005-05:00

Yesterday morning, John Tocci presented on the Autodesk Waltham project. When one of our co-location images was shown, Jim Bratton (Dyna Electric) leaned over to me and remarked that he was disappointed that the only person not using a computer was the electrical engineer.

I was really excited to clarify the image for him. During the working meeting, it didn’t make sense for the electrical engineer to bring his computer over to model – his actual desk was right around the corner. After we resolved items through discussion, he went back to his machine to model in Revit MEP. Furthermore, the electrician had access to both PDF/DWF of the design documents as well as the Revit model. Even though they aren’t technically BIM-enabled, they were so excited about the process that they staffed a full-time person, on site, to navigate through the model for extra information as needed.
This just goes to show that even subcontractors that aren’t BIM-enabled can utilize the model in some capacity. Additionally - the "E" in Revit MEP is functional.

Audit Trail

2009-01-09T09:29:00.004-05:00

Something that people tend to discuss is the need for an audit trail in model authoring tools to facilitate IPD. But I believe it was Wayne Muir (from SCI) countered that point during the Software Vendor panel discussion. He made the case that only lawyers want and benefit from an audit trail. We all need to understand what has changed in the model, but have no need for who did what. These tools enable collaboration; we don’t need to add features that send us back to the traditional litigious process.

On the Autodesk Waltham project, we don’t have any audit trail. We don’t need one (also we couldn't have one even if we wanted one). Because there is trust between all the team members. KlingStubbins trusts that we won’t modify anything without discussion it with them, and we trust that they will notify us of changes they are making, so we can implement them.

I agree with Wayne – it is not about the technology; it’s about the process. Although, as someone else brought up, is that just giving the vendors an excuse not to resolve dysfunction? (Actually, probably not – I don’t believe that vendors want to create less than functional tools that prevent companies from purchasing them.)

Read the Contract

2009-01-09T09:20:00.001-05:00

Mark McDonald, from NBBJ, gave an interesting presentation on Tools for Effective IPD. One of the most interesting points to me was his insistence that the entire team read the contract. This is something we are preparing our team for; although, there is some resistance to reading 70+ pages of “lawyer speak” (as one of our modelers says) for each project. We are having the team read all the available IPD and BIM Addendum-like contracts, and then scheduling discussions in order to ready them to read project-specific contacts. Hopefully some exposure to “lawyer speak” will make it easier to read project-specific contracts.

Mark gave several reasons for why the entire team should read the contract, but the most important is that it: defines what it is expected of the team. I agree with this wholeheartedly.

He also said not to worry about company manuals because the contract is the guide; the team should align the tools to the contract. Although I agree that the team’s tools and processes should be aligned to the contract, but I don’t think that company-specific protocols and manuals should be thrown to the wind.

In a more traditional project, company-specific protocols will most likely govern the interaction and process on the project, because the contract probably won’t. And on IPD projects, the team needs to be prepared to hit the ground running, and experience and company standards will facilitate the integration with other project partners. On of the things that both Sarah & I say about working together is that it was easier to develop standards and work together because of our experience with Revit and company standards. We knew that the other had a lot experience and could be trusted.

Obviously company standards do need to be modified to meet contract requirements (or vice versa), but it is critical to have a base standard.

Steel Penetrations

2009-01-09T09:13:00.005-05:00

One of the stats given on the Solaris project (presented by the BIMForum SCI and Weitz) was the number of steel penetrations incorporated into the model: 18,000 (5,000 reinforced). The number of penetrations enabled the design team to locate ceilings directly at bottom of steel. The reason: to add an extra floor to the building while meeting Vail height requirements. I think these images speak for themselves:

Structural Model for Permit Review

2009-01-09T09:11:00.003-05:00

Another interesting use of the model for the Solaris project (presented at the BIMForum by SCI and Weitz) was during the building permit review process. After discussions with the team, the town of Vail agreed to review the structural model as part of the building review process. The team helped the town navigate through the model to understand and visualize areas.

This use of the model is impressive; there is significant value in speeding up the permit review process by supplying information that is easier to understand and more consistent.

Of course, as towns move in this direction, this may require all of to model to standards specific to permit review. At the very least, we may have to model additional components for the process. I guess we all need to practice with Solibri (which I have been doing for the past few weeks – more on that later).
