Composite Model Strategy p.2

So here's the second part of the post, the how to. I know most have you have heard of WAN and LAN networks, however, what I'd really like to start talking about is how this works within the framework of a BIM collaboration. For those of you who haven't checked it out, I strongly recommend looking at Riverbed Technologies, who essentially has developed a system of network WAN optimizers that allow for multiple users across multiple networks to access and update a single file minimizing the drag on your local (LAN) machines. Although there is quite a large investment involved in the Riverbed and Steelhead systems it does allow users to collaborate using a single Revit model file across the internet. Also it makes it super convenient to enable its use with mobile devices in the field and encrypts the data to meet pretty tough security protocols.

Another new technology to come to the forefront of late is the BIM server. You can apply to test drive this new plugin here.
What's great about this technology is that it allows users to upload and download the latest iterations of BIM files in IFC format from a centralized location. Although this technology is relatively new, it holds the most promise in that it is being developed as a free resource for the industry to plug into and the fact that it has been developed to IFC standards as a baseline makes it a very promising technology.

Book Comes Out in One Week!

Hey everyone! It's been a second since my last post, but as many of you know this was due in large part to writing my book. This book will be released on Amazon may 7th and should hit bookstores on May 9th.

Please feel free to hit me back with responses, questions, dialog and suggestions as this is the first iteration of the book, I would really like for the future editions to address what the issues are that you and your teams face and continue to develop upon this first edition.

Best!

Composite Model Strategy p.1

I recently was asked how to use architects models if they're "trash". While it seems like a good question and easy to ask if you aren't an architect, I have been asked the same from engineers and fabricators by contractors and heard from the architects, what kind of model is the contractor looking for?? Basically everybody is asking why they can't use each other's models. Here's the deal (generally speaking).

- Engineers (mechanical) are using general architecture models to run CFD and daylighting analysis. Here's what's important to have right in the architecture model. First, floors align with the exterior walls, no gaps and if the floor bears on the exterior wall verify it aligns with the internal structure of the wall and doesn't penetrate or overlap the exterior wall finish, otherwise...no go. Next the roof needs to align with the parapet wall, same rules on the exterior finish.

- Contractors are using models for just about everything depending on who you're working with. This means more things than I can probably include in a blog but here is my best shot.

1) Model it right. If the interior walls are 9'-6" high and then diagonally braced to structure above. Model the walls at 9'-6" not to structure. It helps on estimates, clash detection and just about everything else. Accuracy is the first step to a good model.

2) There is no generic modeling. And architects and engineers everywhere say "but what if?" and "won't the contractor lock me into my material selection?"

There are a couple of answers to this and why I say there isn't any generic modeling. First the relationship between the architect and the contractor needs to change. Desgn-build and IPD are great starts to a reformed process, I think that we are probably going to see even more integrated forms of delivery soon. This of course means that a brick wall, can turn into a rainscreen, which can turn into metal panel. This is the very nature of design and construction... things change. So model as the design is being envisioned. The estimating contractor will be making assumptions on construction type and materials anyways, might as well better inform the assuptions being made. If you're wondering why contractors are calling models "worthless" this would be one of those reasons.

3) Design models don't work. BIM isn't CAD. If you're building a BIM to provide a construction tool that helps better coordinate the project than build the model to a level of constructable detail that a GC can use and build from start the dialog with the contractor to find out what they need as well. Construction is a team sport. Otherwise use CAD or use BIM to just generate your CD's, but don't sell it as "doing BIM."

4.) More detailed models replace less detailed models. For example, structural models supercede intial architect structural models. Detailed structural models/fab models supercede structural models.

Well this is a start.... I'll continue this when my daughter isn't needing to go to bed..turns out she's not as into ESPN as daddy...what's up with that?!

Yep Econonomy Isn't the Best...

But what value can you put on the BIM Manager or Virtual Construction Manager during these tumultuous times?

It seems as though BIM professionals are still in hot demand. Specifically on
LinkedIN and the upcoming AEC Fall Conference BIM job fair. I guess this is a blog / input from everyone as to what your take on everything BIM - wise in this current economy is.

I was thinking about the current state of things in our own industry after I read this great article in
WIRED about how an economic downturn = opportunity for innovation. (If you're there read this article too, it's about some kid who made a 200 million dollar company over selling gold on World of Warcraft...scary)

I think that there seems to be a lack of innovation within the BIM world recently. Maybe I'm missing something, but it seemed there for a while it was one software innovation after another, from
Green Building Studio to IES to Vico. Maybe our industry is refining its practices, maybe the industry is making the move to ONE BIG BIM or maybe everyone's checking their 401k accounts and hanging on to the counter at the local bar.

In all though, it feels that the BIM industry continues to thrive and push forward. However, there were recently a significant number of layoffs in the Kansas City area and I couldn't help but think the mistake some of these companies are making. While I can't look at all of their budget sheets and judge or make decisions based on how they handle their HR department, I can look at the talented field of people who are now looking for nothing but BIM jobs.

It's a veritable hey day for architecture and engineering firms that were singing the blues about lack of experienced and knowledgeable personnel in the market!

Here's the catch...you need to hire them now. The personnel available now will NOT be wanting to go back to their old, under paid, repetitive jobs. In fact, employers should really think twice before laying off the BIM Manager as they might cost
twice what they were paying him before to get him back IF he wants to come back.

Considering the average BIM manager is pulling about 95k and the average Sr. Project Architect is pulling 89k, this validates not only the need but the direction of the industry.

My advice to employers, hang on to your BIM department if at all possible.

My advice to those laid off, congratulations. You are now one of the most sought after professionals in the industry.


As always, thoughts and comments appreciated...

It starts...interoperability and singular modeling


So here's some exciting stuff...INTEROPERABILITY!

Recently had a great meeting with some of A-desk's software development task force and found that there is light at the end of the tunnel....hopefully.

So here was in essence the discussion we had.

The first topic of discussion was interoperability. The question came up how important is it? Where we see it being effective and why?

Umm...where to start? Does this meeting involve beer? If not why not?
Moving on.
Interoperability affects all of our professions. Currently, it cripples a lot of the day to day tasks that should be a LOT simpler than what they are. As any BIM Manager or Virtual Construction manager worth their salt will tell you there's always a solution. It just might take half the day to get it there.

During this discussion, I brought up an epiphany I had after talking with a buddy of mine who is a programmer for Apple, Joseph. Joseph is a super smart guy and I revere the fact that he has started up two very successful software companies sold them and continues to work for Apple because he likes the "environment". (I personally prefer the environment in Cancun, but to each their own) So I thought I would throw this issue of interoperability at him.
After asking the question, Joseph thought it was hilarious for some reason! I asked him what was so funny and he said because they faced the same issues in his industry years ago. Apparently Windows' take on interoperability between systems was that they had the "best" solution for PCs out there and that they didn't need to conform to any of the Apple software protocols.

So Apple made their existing systems not only interoperable with Windows but every other "highly used" system available. This included both Unix and Windows software, web interfaces and so on down to the printers and the Ipod. He went on to say that Apple took the stance of change the industry, by example and as a result (sans current economic downturn) saw a revenue growth of almost 200%! With the mantra of, "Plug it in and it has to work. No matter who made it."


Joe also went on to talk about how the answer (in dumbed down terms for me) was filters. He said computers should do the work, humans should make the decisions. Taking data and pushing it through an analysis filter such as (his words) NavisWord, (Joe if you're reading this I have to give you a hard time!) and viewing the results directly in the native format.

Whoa...I thought. Native format huh? He said "Yeah you know whatever you created the file in is inherently where the most data and toolsets reside otherwise you wouldn't have been capable of creating it. He said the key is the same base language otherwise you end up with a Tower of babel situation. In programming if the language is C++ than the entire team knows how to work with it. This doesn't mean that designers have to use the same software that database programmers use or that interface programmers use. What we're talking about here is use the tool that makes it easiest for you, so long as you can get the information in the end to C++. It's not rocket science man....everything needs to talk the same language. In the end after you push it through these filters, fix it, test it, filter it, fix it, test it for about 30 times you end up with a useable product."

Now I'm just a lowly BIM guy, but it seems to me that there are some direct parallels here. The fact is that BIM as a deliverable needs to remain in the native file format. (Revit, Bentley, ArchiCAD) however, filters such as clash detection, energy analysis, estimating bring value to the table as they accomplish testing tasks that the native software isn't capable of. Lastly, exporting the product in the form of animations, stills and graphics are a snapshot in time and shouldn't be relied on other than visualizataion and better communication of the idea.

In the end, the Autodesk boys were sitting there, with that aha look on their face. Hopefully they go back to the rest of the team and expand upon Apple's model that interoperability isn't "optional" it's a way to be more profitable! Of course, we are talking about the software industry and sometimes that takes a while....

Also I wanted to thank Joe for his take on the interoperability issue.

Brads Take on Parallel Modeling

Recently I was asked why I try so hard to keep a singular model in Revit using the architects', MEP and structural information when I could just as easily create my own.

Great question.

My answer was, "Because there is only one google."

Needless to say this slightly confused the person asking the question who couldn't seem to draw the parallel I was trying to make.

I further elaborated on this concept and point.

BIM is not CAD.

BIM will not and should not be forced to function in the same way we have been using CAD for the past couple of decades. The old CAD way had us managing hundreds or thousands of CAD drawings that were somewhat organized in a format we pray can be managed later in the project when due to schedule constraints the project manager throws thirteen new and strange people to draft on the project. Where more often than not they are inputting loads of information that is incorrect, contradicts other drawings or the specs and then wonder why document quality stinks.

CAD is a series of information silos. No I don't care about xreferenced drawings.

BIM is not an information silo.

So to get back to my point. There is only one google.

Google is a great example of one source of user entry, input and extraction that streamlines and manages the information for the user in a useful way. Currently valued at over 158 billion dollars, even in a time of recession, (people need information now more than ever..) there is something to be said for the value this tool creates. That said there is no separate site for any of the following:

- Google for Engineers
- Google for Architects
- Google for Construction Managers
- Google for Subcontractors
- Google for Field Personnel
- Google for Estimators
- Google for Owners
- Google for Code Compliance
- Google for Sustainability
- Google for Facility Managers
lastly...

No specific Google for BIM Managers, Virtual Construction Managers....either

The real value and appeal of Google is a single source of information.

A fundamental screw up in the way our industry is heading is not working together to begin building an actual honest to god usable tool. It's easy for us general contractors to get in a rush, think we're more important than the rest of the team and fail to understand the value of educating the team above to create BIM's correctly as opposed to wasting a lot of time and resources of the course of the next 111 projects with the same team or same members.

Conversely, GC's need to gain an understanding of what is important to the team members to see from us (GC's). Turns out no one on the team knows it all and the better we can facilitate answers for the team the better results.

....just like Google.

Beginning of the Consortium and the Cassagnes Rating

INTRODUCTION TO THE CONSORTIUM for REALLY AMAZING PERIPHERAL DEVICES
(CRAPD)

So Brian (a gifted and talented gadget guru/BIM expert) and I got to thinking it would be a good idea to take a break from talking about BIM for a moment and delve into how we got where we were and whose shoulders we are now perched upon.

Thus, we are going to begin a satire filled series on Fridays called Technology vs. Man.
This analysis will take an in depth look at how,(in the history of mankind) technology has helped, hindered, hurt, humiliated or in the rare case delivered a moment of hopeful euphoria. As such we have create the CONSORTIUM for REALLY AMAZING PERIPHERAL DEVICES. We hope you understand this consortium is open to the public for commenting and further non-gratis studies.
In this session we will look at the very beginnings of technology...the Etch a Sketch:

Simplicity+Function=Beautiful Device


Say what you will about technology, without the introduction of the Etch a Sketch into the area of "kick-ass" technology, we at the Consortium doubt very seriously we would be where we are today.

Invented in 1950 by André Cassagnes the Etch a Sketch was originally called the Telecran ("tele-screen"). As a dedication to Cassagnes and his life changing invention we will rate all further technologies on a Cassagnes scale. This scale will be rendered out of 512 and will indicate the level of "kick-ass"edness, thus inherent in the device.

Image of "Kick Ass" Cassagnes..





Moving on, Cassagnes' device receives a 511 out of 512. The -1 one rating is because the name "Telecran" should have been used and thus fully and completely "kicking ass". That said 511 is still way beyond any rating thus far...clearly and thus elates us everyday we get to use this wonderful device.


THE INNER CIRCLE


The Etch a Sketch works by having the inside surface of the glass screen coated with aluminum powder which is then scraped off by a movable stylus, leaving a dark line on the light gray screen.
The stylus is controlled by the two large knobs, or "Knobbies" one of which moves it vertically and the other horizontally.

To erase the picture, the artist turns the device upside down and shakes it. Doing this causes the styrene beads to smooth out and re-coat the inside surface of the screen with aluminum powder. The "black" line merely exposes the darkness inside the device.
While many might question the rating we at the "Consortium for Really Appealing Peripheral Devices" or simply CRAPD; we stand firm behind Andre's glorious device. One because we used it as kids and secondly we couldn't think of any other device that perfectly balances form, function and simplicity quite like the EAS.

TOP SECRET


Filling in large "black" areas will allow enough light through to expose parts of the interior. This is of course top secret information and available to only the true students of the EAS (Etch-a-Sketch).


NEXT GEN TECHNOLOGY
Many people fail to realize that the Etch-a-Sketch was father to another device, the Animator.



Visionary Machinery for the Space Age...or Animating Peeling a Banana.


Released in 1986, the Animator reaches a level of "kick assedness" rarely seen from the Consortium. Walking a fine line of yin and yang, form and technology, and unadulterated pleasure the animator defines the form and function of the modern day laptop/mobile device.


While single handedly wowing the industry the Animator burst onto the scene only to be quickly taken off as scientists scratched their collective heads in awe and disbelief and scrambled to develop laptop technology....A coincedence?




Scientists diligently finding the innerworkings of the Animator
We think not.Literally...

The EAS and Animator essentially defined to laptop designers everywhere what their product is supposed to do and how it is to function.


TWENTY TWO YEARS!!!

That's how long before the modern day the animator existed for this reason we compare the following:


VS.















Sure the modern animator has some more bells and whistles than the Original Animators functions as follows-

- ON/Move

- Animate

- Save

- Draw

- Next

- Reverse

- Recall

- Erase

But these functions pretty well sum up the functions of our modern day laptops and tablet PC's anwyays! So here here!! To the Animator and its Cassagnes rating of 511.544!

Congratulations! You sir are an innovator, a pilgrim and a true champion of modern technology!
