Disney BIM : 2D, 3D, 4D, 5D, 6D, More. Jack Blitch from Disney presents BIM at NASA Info Tech Summit
Por Jim Foster - BIM, New Technologies - August 20, 2010
Jack Blitch, VP Disney Imagineering, presented at Day 2 of the NASA Information Technology Summit on August 17 and discussed BIM and IPD. His comments really start at 1:06 mark and move forward from there. What I find interesting and really reiterates the process of BIM, call it IPD, call it smart, but bringing in the sub-contractors early to reduce rework and make sure the designers are creating anything that can’t be built or is too expensive. I brought in some of the transcript below.
We bring in subcontractors early to help with design instead of our designers designing something maybe we can’t afford or doesn’t make sense. We have the guys that are building it sitting at the design table with us…we want to reduce rework, use it as a constructability tool…determine clashes early so we don’t (find) them out on sight. Reduce personnel. Reduce shop drawings… So the shop drawings come right out of the model so the vendors/sub contractors don’t have to redesign. – Jack Blitch, NASA Summit
In case the video is not coming up you can go directly to http://tiny.cc/nasabimdisney , as either the CSPAN embed, or WordPress is not dealing well.
Stitch Kingdom also covered the summit and summarized Blitch’s comments and I’ve included some of them here.
Using the Fantasyland Expansion as the primary example, Blitch demonstrates how Building Information Modeling (BIM) and Integrated Project Delivery (IPD) users computers to generate ‘6-D models’ to engineer a project before the construction beings, a concept pioneered by Disney in an effort to reduce costs and speed construction by avoiding potential problems on-site. Disney began using BIM-IPD on Soarin’ and — as an example — Blitch stated that had Expedition Everest been engineered using traditional methods, it would consist of approximately 20,000 construction documents.
Using The Little Mermaid: Ariel’s Undersea Adventure as an example of the BIM-IPD process, Blitch demonstrates how 3D modeling has evolved into 4D modeling in which the computerized model can actually project the construction over time which the Imagineers then use as a guideline for the attraction’s construction. Blitch adds a 5th and 6th dimension to the project development which covers cost as well as the capability of exporting various components of an attraction’s construction to its respective contractor/partner.
BIM CAD Throwdown : Dassault Takes Aim with Catia Live Building and Draftsight
Por Jim Foster - 3D, BIM, New Technologies, Open Standard, SaaS, cloud - July 30, 2010
Holy frontal assault Batman. Dassault, the french producer of CATIA (Computer Aided Three-dimensional Interactive Application) / Solidworks is making a strong move into the world of architecture. CATIA, generally used in the aerospace and engineering fields, has also been used successfully by Gehry to produce his curvilinear buildings. They are now introducing 2 products aimed squarely at the Autodesk Bullseye, a CAD application developed through the IntelliCAD Consortium (ITC) and the Open Drawing Alliance (ODA) called Draftsight and its going to be free, yup free. And is available here.
And while it is available for the Windows Family of OS (XP / Vista / Seven) MAC and Linux versions are in the pipeline, take that into account that IBM, you’ve heard of them, markets these solutions worldwide and that complaints about Revit not handling larger products are scattered across user groups and BIM forums one can believe there is an opening. Additionally, if they are following the SaaS path of putting Draftsight in the cloud for file sharing/integrity it becomes a pretty powerful argument to think about switching, especially if all the ingrained keystroke commands and shortcuts from AutoCAD are copied along with it. Having seen the Intellicad interface, I think that most likely a yes.
Excellent article at AEC Magazine that covers the introduction in depth, and thanks to @amonle / John Allsopp twitter for bringing this to my attention. I’ve included a portion below.
Based on a future version of Catia and its data management system Enovia, Dassault Systèmes is developing a competitive parametric modelling solution to compete with Autodesk’s Revit BIM (Building Information Modelling) tool. I understand that the next update of Catia will store its data in the cloud and Catia will potentially be downloaded and licensed from the desktop. This will enable Dassault Systèmes to overcome the fact that it does not have a value-added reseller channel to sell Catia Live Building but needs to compete with an established and low-cost player.
The brief demonstration showed an architectural model being rapidly developed and edited using Catia. Bernard Charlès said that the new product could do modelling in seconds, what Revit would take 45 minutes to do. And Dassault Systèmes should know — it was among the many original investors in the start-up company that developed the first version of Revit.
While Revit has captured the mindshare here in the US and Down Under among other places no one can discount the Dassault / IBM alliance and their entrance into the AEC industry in a big way. The amount of consulting opportunities and hardware sales should have IBM salivating. So if Draftsight is free, what is Live Building coming in at?
A Better Blueprint in Maine : #bim
Por Jim Foster - Adoption, BIM - July 29, 2010
Reported in Maine Biz by Robert Cook, and brought to my attention by John Stebbins (@johnstebbins), this article shows the full black bear hug Maine contractors are putting on BIM.
Denis St. Pierre knew sooner or later E.S. Boulos Co. would need to add Building Information Modeling technology to its skill set if it, the largest electrical contractor in northern New England, wanted to remain competitive on large-scale projects.
The nudge came sooner, says St. Pierre, the company’s director of estimating and project management, when in June the Westbrook contractor won a bid linked to the $75 million terminal expansion at Portland International Jetport. The project’s lead contractor, Turner Construction of Boston, requires all companies involved in the jetport project to use BIM, a 3-D hardware and software tool that allows multiple contractors to see the location and status of all project components.
John O’Dea, CEO of the Associated General Contractors of Maine in Augusta, says BIM technology is not new, but it is just starting to find its way into some of the state’s smaller and mid-sized construction firms, usually as the need presents itself.
“It’s heavily dependent on the market and the size of the project,” he says.
Many small construction firms still rely on AutoCAD drawings and more traditional planning tools for smaller-scale projects, says O’Dea, but they would be wise to adopt the BIM technology — the 21st century version of a blueprint — because demand is increasing.
“The genie’s never going back into the bottle,” says O’Dea, whose organization represents 250 members.
Recently we’re seeing reports from Maine to Malaysia on BIM adoption…fire up the bandwagon.
Department of Energy (DOE) Launches New Blog : Energy Blog : Yawn? : BIM
Por Jim Foster - BIM, Energy Analysis - July 27, 2010
As reported by Katherine Tweed from GreenTech Media and picked up by Wired the DOE Launched a new blog. (Man, this new media everybody ‘borrowing’ and ‘sharing’ content gets tough to footnote). Alone, generally, this should be met with a collective YAWN. However, as a thread of the whole fabric it adds strength to the perception and reality of the move to a sustainable future and the real investment that is happening around it. And get this from a post on July 23.
…Cindy Regnier (from the) Lawrence Berkeley National Laboratory… works on several projects, including two that are Recovery Act-funded: the new User Facility for Low-Energy Integrated Building Systems test bed and the Commercial Building Partnerships initiative)…is helping to select dozens of new and existing commercial building projects from around the country to receive technical assistance from the national labs to achieve 50% energy savings in new construction and 30% in existing buildings. Each building will have energy-savings measures validated and evaluated from energy and cost standpoints, all with the goal of developing and promoting energy efficiency measures that can be easily deployed throughout the industry.
So not completely dull, and if you keep an eye on this project you might find out where the government might focus more efforts for existing buildings, techniques, tools, products, etc. For example, I wonder what technologies and assistance Ms. Weigner might be deploying herself. Cindy give me a shout.
The blog itself is available here
BIM Malaysia is on Board : BIM Adoption increasing
Por Jim Foster - Adoption, BIM - July 26, 2010
Like the GSA, the State of Wisconsin, the State of Texas, now the country of Malaysia is on the board according to to this recent article in the Malay Mail.
Public Works Department (PWD) director-general Datuk Seri Dr Judin Abdul Karim said the department, in supporting the government’s desire to maximise the value of investment throughout the development plans, would utilise and enforced various ICT solutions in its strategies. This includes to spearhead the adoption and usage at all levels of Building Information Modeling (BIM) software and applications in building design.
The theme of this brief article seemed to be get on board or get left behind. “Geez Jim would you get off this BIM bandwagon,” I hear some of you saying, although I doubt you’re reading this if you are not right behind me playing the tuba, “you’re worse than the ice cream truck at little league games.” However I call them like a I see them, and I do understand the legacy tail of 2D and traditional CAD is long and will be with us for a very long time, not only that, I believe there will be a large market for hybrid technologies and also ones making CAD better but no one ever argued the development of the jet engine and its almost complete adoption in the aviation industry, except for maybe those companies just making propellers.
Using BIM for Sustainable Design
Por Jim Foster - BIM, Sustainable Retrofits - July 26, 2010
Good article in Architecture Week titled, strangely enough, Using BIM for Sustainable Design, I guess we’re getting that horse out of the stable again, but this is it. Like AARA funds and the stimulus package put every paver and asphalt layer in the US back to work, sustainable design and retrofits are and will be it. Eddy Kryiegel, the author, goes on to elaborate the ease that option analysis and energy modeling that comes with BIM.
In the case of energy modeling and its relationship to BIM, there are three primary steps involved: modeling the building geometry, adding building loads, and performing the analysis.
If you compare the time it takes to perform each of these steps for the same building type across a variety of analysis packages, you will see very similar results. During years of integrated practice, I have found that more than 50 percent of the overall time needed to perform an energy analysis is consumed by modeling building geometry.
Adding building loads accounts for about 35 percent, followed by less than 15 percent to perform the actual analysis. By simply being able to reuse the model geometry and transfer the building design from the BIM model to the energy model, we can reduce the time needed to run an energy model by almost half.
The traditional process of energy modeling within our own office typically takes a couple weeks. Using the workflow established with BIM, we can now perform some types of energy analysis in half the time, do twice as many as before, or make energy analysis available to projects that would normally not have the fee to support the endeavor.
A) If a project is started in BIM more services can be offered whereas they were too expensive the traditional way, and B) with option analysis you can find ways to make your building more efficient, demonstrate that with positive ROIs and have the analysis and design pay for itself. Just keeps on getting more compelling, like the Lebron laugh-a-lympics televised special, no strike that, like Lindsey..strike that, like having your cake and eating it too.
Photofly : Real 3D from Photos : Cloud Computing Magic : #bim #cloud
Por Jim Foster - Autodesk, BIM, Existing Conditions, Laser Scanning, New Technologies - July 24, 2010
While I have not taken this for a test drive yet the videos and technology behind this are impressive and could provide a very valuable tool set. First, a word about technology. Too many times software presupposes too much knowledge or interest on the user, that is this software can do some amazing stuff you just have to sit down with it, go through the manual, try and use it, sit in a classroom, hit the user groups, etc. to master it and make it a useful and successfully incorporate into your workflow. If you are like me you might be open minded to that but the benefits of learning a brand new software package have to be pretty amazing to entertain that process. Enter Photofly. From what I have pulled up and I included two videos here you upload standard digital photographs, which could range from your iphone to your 18 Megapixel Digital SLR, and Photofly does its magic in the cloud utilizing its own servers to render a photographic 3D image, that can be scaled using a known dimension to a dimensionally correct model that can also be exported to AutoCAD as a pointcloud. What?!$% From my perspective this is invaluable, and brings to the forefront technology that was only available from laser scanners. I am not saying this takes their place but any time you can put another arrow in your quiver for building surveying and documentation, the better. And if this is as intuitive as these 2 videos make it out to be, this is a home run.

Design Build Boom : AECOM acquires Tishman : #BIM
Por Jim Foster - BIM, Virtual Construction, economic trends - July 16, 2010
I have suggested among others that the optimum work flow could be architects focus on the design, not construction docs or the BIM, but the design and then consult during the actual engineering and BIM process, that way it minimizes redundant efforts especially in regards to BIM creation. This process also would suggest the rise of design/build firms. AECOM just took a huge bite out of that apple when terms were disclosed yesterday that they agreed to acquire Tishman for $245 Million Dollars creating a design/build behemoth. Strategically, vertical integration is a double edged sword. Positively, you have control of costs and quality and capture every last dime a developer was intending to put into the project. Negatively, you have to feed the beast and can you really be that good at all disciplines?
On a side note, I was speaking to an integration specialist at Bentley who told me AECOM was a Microstation shop. This may be because back in the day the US Government was using a lot of Microstation and AECOM gets the majority of their work from the public sector. Tishman, and I am only speculating here, was most likely Revit. Skidmore, Owings & Merrill LLP (SOM) used Revit at World Trade and Tishman was on as construction. Quick google search shows they still seem to use it on current projects. Future projects and technology they use could be a proxy for the industry.
CALGreen is Coming : More Markets for Energy Analysis : Green Building : #BIM
Por Jim Foster - BIM, Green, Sustainable Retrofits - July 13, 2010
Signed in 2004, mandatory in 2011 Executive Order S-20-04 set in motion a whole new set of building codes to reduce energy purchases by 20% by 2015. I included section 1 and 2 in their entirety below.
1. That the state commit to aggressive action to reduce state building electricity usage by retrofitting, building and operating the most energy and resource efficient buildings by taking all cost-effective measures described in the Green Building Action Plan for facilities owned, funded or leased by the state and to encourage cities, counties and schools to do the same.
2. That state agencies, departments, and other entities under the direct executive authority of the Governor cooperate in taking measures to reduce grid-based energy purchases for state-owned buildings by 20% by 2015, through cost-effective efficiency measures and distributed generation technologies; these measures should include but not be limited to: 2.1. Designing, constructing and operating all new and renovated state-owned facilities paid for with state funds as “LEED Silver” or higher certified buildings; and 2.2. Identifying the most appropriate financing and project delivery mechanisms to achieve these goals; and 2.3. Seeking out office space leases in buildings with a U.S. EPA Energy Star rating; and 2.4. Purchasing or operating Energy Star electrical equipment whenever cost-effective.
Not only that, within the Executive Order their is a provision for CALPERS (the California Pension plan and huge investor) are ‘requested to target resource efficient buildings for real estate investments and commit clean technology funds to advanced sustainable and efficiency technologies.’
You can jump the new building codes home page here. With the GSA requiring a BIM on all new building and major renovations and now California requiring Green Building Practices in all their public buildings the increase in new technologies related to building will continue to grow. To completely beat the dead horse into submission, not that a dead horse needs to be beat any more, metaphorically speaking, but…sustainable retrofits, say it again…
The Building IS the operating system : BIM – SketchUp – Revit Free?
Por Jim Foster - Autodesk, BIM, Open Standard - July 8, 2010
If you free it, they will come. Hasn’t that been proven many times over in the software world? Not always the most viable business model, but sure to gain traction and then we can figure out the revenue streams, or the revenue streams will figure themselves out as we get volume. If the majority of what you do on the web is surfing and e-mailing, the software you use is free. If you are composing spreadsheets and documents using google docs and/or Open Office it is free. It’s really the value you imbue these documents with that have value and people are starting pay for. Your the NYTimes and your content is important to people, you sell ads. Your facebook, well it will be ads again, or maybe facebook gets a cut from all the digital nothingness people buy in the form of cyber poker chips and farm tools from Zynga but I’m getting off point.
Think of the building, or the digital manifestation of the building as the operating system, the OS. Now I want to run an energy analysis on the building, heating and cooling loads, solar analysis, or I want to do a cost analysis on sustainable retrofits, or even new construction. It can all start with generic structure or masses, that is I have generic mass of blocks and objects, it’s when it has to be put into context that it needs to be defined. From this is a wall, and this is a window, to this is a steel stud wall with 3/8″ gyp on each side, and this is a window with triple pane low-e glass, etc. It depends on what you need it for that it needs to be defined, energy analysis you want the R values, cost analysis for construction, types, and even then you may not want to populate that whole model with those defined types because it gets huge and you might not need it.
For all the different people who interface with the building the idea of a centralized model is an awesome thing, and it has been the idea of BIM that has brought this forward. However, think of having the BIM in the cloud, and now it becomes the OS and I want to build applications for it. Energy Analysis, Cost Analysis, Maintenance Contracts, Build Outs, etc. etc. it opens the building to the market. And if it can start as generic components and then people pick and choose what type of data and services they want to use to add value well it starts to sound like the iphone and the app store, or android and the app store, or facebook with Zynga, etc. that is free at first but customers willing to pay for the things that give them value. We can all argue the benefits of why having a BIM of your building allows you to manage what may be your biggest asset more efficiently and save money, energy, etc. however, combine those things with free, well that’s where SketchUp is bringing us, the free building OS, and we’re all going to be playing in the app store.
