3D from Photographs : #BIM #3D
Por Jim Foster - 3D, BIM, Built Environment - 23/Feb/2010
The world wants an easier way to get 3D. Photographic manipulation has been around for awhile. I remember sitting in a presentation by Yonald Chery for Mok3 which created photo immersive 3D, and this was back in 2004. The technology is still used today in something called supertour. A quote from 2004 at the time-
“This Mok3 thing could be bigger than SketchUp, especially for interior designers and architects,” Geoffrey Moore Langdon tells me. “It is like a PhotoShop that allows you to push-pull the images into correct 3D with the ease of SketchUp. Thus from a single photograph, you quickly create a 3D model:
It was ahead of its time, but we are seeing more entrants into the field. Autodesk acquired RealVIZ and its Image Modeler software, you can view a demo here. And today in the NY Times today there is the article Computers Turn Flat Photos into 3-D Buildings. Where they are using a crowd sourcing/social media aspect to data collection and improving the algorithms to stitch this stuff together. A project out of Cornell and University of Washington morphed into Microsoft’s Photosynth where you can view 3D images that have been stitched into “quasi 3D” through a browser. However, Photosynth appears to be limited by the number of photographs and data so the bigger desire was to scale this thing. So the same folks have been crunching more numbers and algorithms to create a more robust platform and a web site called Photocity was created entice people to add data and create the digital 3D construction of the WORLD, okay maybe not the world but then again…
Public Beta Open in January : Capture as builts in Revit in the field: #Revit #BIM #asbuilt #laser #pplt
Por Jim Foster - As Builts, BIM, Built Environment, Existing Conditions, Laser BIM, Laser Scanning - 16/Dec/2009
We will be opening up our beta to public testing in January and we are asking for volunteers. Our product PKNail allows a user to use a hand held laser, Disto D8, and measure and build Revit models in the field. The measurements are transmitted via bluetooth to a mobile workstation which allows the user to quickly and accurately captures a building geometry and features. On board intelligence allows users to determine wall thicknesses, wall angles, toggle accuracy, attach notes to objects and more.
PKNail was developed by field surveyors and software engineers to help the AEC Community quickly and accurately capture a building’s geometry in Revit. This tool used alone of in conjunction with HDLS (High Definition Laser Scanning) can let you start any project in BIM / Revit. Proven ROI in as little as one project, and speed gains from measuring to model of over 200%.
With the majority of construction projects happening in the built environment, and in cities like Boston almost 80% done in the built environment start them in BIM and help everyone downstream.
This a powerful tool in capturing as builts in Revit and beta testers will be eligible for a substantial discount when purchasing.

Revit and Rockband
Por Jim Foster - BIM, Built Environment, GSA, Revit - 16/Sep/2009
No the two do not have anything to do with each other but just describing my day. It started to get on the road early to get to a site an hour away where we are creating a Revit model of an existing building. The building has 5 structures inter-joined over the years with the oldest dating to 1761 and the youngest being a large addition in 1984. Multiple construction methods, floor levels, etc. make it a challenge but utilizing our PPLT (Point to Point Laser Technology) made the base model creation pretty quick, considering. I then realized I signed myself up for two engagements, one was the Boston Revit User Group meetup hosted by Shepley Bullfinch and the other other was a Tech Tuesday hosted at Microsoft’s NERD (New England Research Development) Center, clever, no?
I was impressed with the meetup group because you had a large amount of people from different companies and disciplines discussing Revit and best practices. While I was only able to stay for one of three presentations everyone was open in discussing the project and how they went about it, how to set up projects for programming and even rendering tips were coming out of the audience. I think any environment where people are freely sharing ideas a great place, and it seems Revit and BIM requires this kind of collaboration and it was refreshing. I then hustled across the river to Cambridge and the NERD center to see what was up, collect my free drink ticket and take part of the free pizza. Harmonix was there and had set up Rock Band- Beatles on the main part of the floor which was being displayed on a huge screen, I would recommend playing rock band in this format if you can swing it. Lively crew and I saw some gray beards walking around which I believe were some of the original engineers at BBN.
Also found out the first project from GSA award should be out by Friday. I feel fortunate to be part of the team that won one of the awards but its going to be interesting to see how the multi-disciplinary jigsaw puzzle is going to be put together. And got a call from Australia, at my house, from a person about PointKnown, the pencil scratched note from my wife mentioned ‘distribution.’ Saddle up.
Revit Existing Conditions and As Builts Picking Up Pace : #BIM #Revit
Por Jim Foster - As Builts, BIM, Built Environment, Existing Conditions, GSA, Laser BIM, Revit - 9/Sep/2009
My company’s primary focus is to document existing conditions and deliver to the client ’something’ dimensionally correct. This something has typically been 2D drawings, floorplans, elevations, sections, etc. We have utilized Revit on jobs that have required such extensive documentation that it was simply more efficient to create a 3D model and export the 2D data then document and draw the traditional way. In fact, we have documented existing conditions in 3D since 2003 because it was always simpler to be in and object oriented environment. However, the deliverables remained in 2D. However, almost everything we have done in the last 3 months has been Revit and delivering existing conditions building models in Revit. And the uses of the model vary widely.
- We surveyed and delivered a Revit model of two dormitories for a University in Revit, even though they did not have an installed seat, because they wanted to prepare for the future.
- We completed a Revit model of a single floor of Class A Office Space to be used for new interior layouts and design
- We are in the process of surveying and creating a model of a sprawling historic in built in parts starting with the main building in 1760 to a new hall built in 1984. This is to be used for master planning of the site which they will use for rendering and analysis and to integrate a new building that will house a new lobby and 50+ guest rooms.
So the uses of Revit are expanding, and even if they are not being used for 4D and 5D purposes its benefits for visual communication, analysis, and increased speed of design/drafting cannot be discounted. However, when integrating among all disciplines the results can be outstanding across the board.
We were fortunate enough to be part of the successful team, through a fantastic effort put forth by HNTB, that will be involved with the GSA and surveying and modeling their properties nationwide. What we have seen is either through the ripple effect or from other companies just being proactive that Revit and BIM are making a lot of headway into the community. Companies that we work with report that they hope to be doing all their projects in Revit by this time next year and with new ways of doing work, and changing workflow and even the environment comes opportunity.
Summer Thaw, Projects on the Rise: #BIM
Por Jim Foster - 3D, As Builts, BIM, Built Environment, Laser BIM, New Technologies, Revit, architects - 19/Aug/2009
I have always thought companies like mine are like the canaries in the coal mine for part of the industry, like box companies as an indicator for the overall economy. When companies start ordering more boxes they are expecting to ship more product. Our company surveys buildings and provides as builts in both 3D BIM and 2D CAD formats. When times are flush we operate much like others enjoying the benefit, but as projects start to dry up, firms will immediately pull back outsourcing to keep employees busy rather than laying them off. This impacts us greatly. When the economy turns the inverse is true, and firm wary of hiring yet or not having enough stuff turn to us to augment their services without increasing head count. While I might argue that might be a prudent way to do business generally we ride the tide like everyone else. Having said that there has been a very perceptible uptick in business and companies asking us for proposals. More germane to the BIM world is people asking about Revit and asking for more Revit deliverables. A University even asked us after our presentations to deliver their dorms in Revit even though they did not even have an installed seat of Revit but wanted to plan for the future. Yesterday an architect I spoke to said they are now doing 70% of their work in Revit and that clients love seeing their projects in 3D, so even with the economic benefits of working in BIM are real no one should discount the importance of visual communication. This has been a rough ride but I believe more strongly than ever that a fundamental shift has taken place in the building and design community and investing now in training in BIM will pay dividends well into the future.
The Rise of Virtual Construction: #BIM
Por Jim Foster - As Builts, BIM, Built Environment, Revit, Virtual Construction - 17/Aug/2009
When I first started my company at one of our presentations after explaining we could capture as-builts in 3D, then ADT, now Revit, one of the architects in the room stood up and emphatically said, “we don’t want ANY Z-axis information.” To which I replied, “not a problem we can flatten all the drawings.” But that response still resonates with me, how could anyone not want Z- axis information, how come you would want me to strip all the meta data of an object to just a block, to which I have found out, you do not mess with the workflow of an architect’s office so it is of little surprise that construction mangers seem to be the current biggest adopters of BIM and Revit as they are ultimately on the hook for cost management. With that said you have construction managers around the country opening up virtual construction offices to figure out the design, reduce collisions, schedule sub-contracts, etc. before a shovel is ever put in the ground. This is a big change in the zeitgeist since before everyone looked at soft costs, (i.e. engineering and design) as some fuzzy math and did not appreciate it as much as pouring concrete or erecting steel, as that was at least the physical embodiment of the money developers put up. Getting digital files that could fit on a thumb drive just did not seem big enough. Virtual construction has proven itself to pay for itself may times over through quicker build time, less collisions, better decision making, etc and BIM is enabling it. Viva la Z Axis.
GSA BIM & Laser Scanning : Firms Short Listed
Por Jim Foster - As Builts, Built Environment, GSA, Laser BIM, Uncategorized - 30/Jul/2009
The GSA continues to move forward with the BIM Services and Laser Scanning. Participating firms have been notified if they have been short listed, however, this has not been made public yet. I’ll post when I find out, if anyone else knows, please follow up. This move, with Wisconsin on board, energy analysis becoming required with construction, points well for those involved.

PointKnown website www.pointknown.com has its splash page up and expects to be in beta within the next 6 weeks. PointKnown has developed a system that takes laser range finder data and builds Revit models in the field. Point to Point Laser Technology (PPLT) increases the capture of existing conditions, speeds the production of BIM and Revit Models of the built environment and decreases data gathering and draft time by over 50%.
Building Green with BIM : Existing Conditions
Por Jim Foster - As Builts, BIM, Built Environment, Energy Analysis, Existing Conditions, Green, LEED, Point to Point Laser Technology, ROI - 17/Jul/2009
I wondered ho much of the green movement would get sidelined due to the tanking economy, and how much acceleration LEED certified projects will continue to get. Regardless of LEED though going green is proving to be cost effective, so effect on the bottom line are always going to get noticed. BIM allows option analysis from an energy perspective. You can perform solar analysis, heat gain/loss, options to replace glass with low-e, double paned, or triple paned, and run your ROI on a project by project basis. What is the payback by re insulating or upgrading the power plant is much easier calculated with a BIM. A recent article by Karl Heitman in the REournal goes on to say that you need to take into account the “embodied energy” in a building and that it would take 75 years of LEED Platinum Certified Building to repay the loss of tearing it down. So need to refit and reuse, create great projects with your existing conditions.
How you can capture existing conditions in a BIM format? So far, not so easy.
BIM : Contractors Reporting Big ROI
Por Jim Foster - BIM, Built Environment, ROI, Virtual Construction - 9/Jul/2009
I the May/June Addition of Constructor Magazine, there are some excellent examples of Contractors using BIM. One high light was that over 1/3 responded with over 100% ROI. And more and more your finding contractors creating whole departments, aptly and somewhat spookily called “Virtual Construction Departments”. I guess I find it spooky in the sense that so many in the disciplines thought if you were not pouring concrete or putting steel up you were not adding value, however, with BIM we are starting to see a tremendous effort on the front end.
Gilbane Building in Providence found over 1,445 clashes in a 96,000 SF data center saving the owner over $800,000 in resolved issues. All in they believed they saved the owner more than $1,000,000 while investing only $63,000 in BIM expenses. Half of which was creating a BIM from 2D documents, etc.
Great Stuff, Read the Article.
