Survey Angled Walls in Revit with a Disto and PKNail

One of the tougher issues and part of any surveyors work flow is to capture non-orthogonal (i.e. angled) geometry correctly the first time.  This increases in importance if the angles are played throughout the building and especially if they are part of the exterior.  In order to help users capture a building’s geometry in Revit while in the field PointKnown has incorporated triangulation and a close room function as part of our PKNail Building Surveying Software.   Having the Disto drive Revit allows quicker data capture and increased accuracy.  And while many of  us might want to be watching videos of the beach in August I still included the process here as well.

Revit As Built : Field BIM Technology : Build Digitally As You Measure : #BIM #Revit

It’s been a haul and it starts with a quote from Irwin Jungreis one of the founders of Revit who I spoke to early in the process, ‘we never intended Revit to have an API,’ he said with a smile. ” It was supposed to be so good it would never need 3rd Party applications.”  “WHAT?!” you say.  I believe Irwin at the point understood the original hubris of that statement but then again I spoke to him after they sold out to Autodesk.  “So what” we thought and we continued to forge ahead with an  API that had as much horsepower as my old Puch moped.  Thank you Autodesk for your continued efforts in beefing up the API but it has been a bear.

PointKnown is getting closer to releasing the commercial version of PKNail;  it’s building surveying software.  PKNail was programmed behind 7 years of building surveying experience.   Our intention was to:

  • Automate many of the rote tasks when creating existing conditions surveys of a building
  • Create repeatable work flows
  • Increase speed and accuracy by linking measurements directly into Revit

We understand surveying can be the bane of some people’s existence and it is a necessary evil to almost all projects, that is having accurate information to start the project.  While we never considered it a bane or evil but when we would put on  lunch and learns and dog and pony shows we usually got one of two reactions.  One, where have you been my whole life I hate surveying or two, will you sell us the software because we do all our own measuring.  We get it.  And building in real time, in the field makes thing easier and building inside a familiar platform, and one that you will be designing or working in anyway makes you more productive right out of the box.  I look forward to your feedback, comments we’re here to work with you.  And to summarize my last statement in the video, ‘We’re much better at designing surveying  software than making videos,’ but even comments on our production and lack of directing talents are welcome.  Thanks for reading.  – jim

Revit As Built : Field BIM : Existing Conditions

While I don’t usually take the time to pump my own gas with this blog I wanted to share the complete reversal in our deliverables over the last year.  It used to be, way back at the end of 2008 that we delivered most of our building surveys in 2D AutoCAD format, now we would build in 3D, normally in ADT but our clients wanted 2D AutoCAD.  From a surveying perspective a 3D object oriented universe worked better for us because essentially all the views were coordinated, that is build it in the floorplan directly, it is represented in elevation correctly.  Anyone who has keyed up a plan in 2D knows where I am coming from, which if you are here reading this, means you know what I am talking about.  Now, however, the bulk of what we do is deliver as-builts in Revit.  The GSA requiring BIM has a lot to do with it, I believe, and Autodesk being the biggest player in the US means Revit becomes the default.  Whether you like that or not does not matter, that’s the reality.

Recently we have performed as built surveys at Phillips Exeter and Emmanuel College and we were field testing our laser to BIM technology, PKNail.  It was created to capture typical conditions quickly and accurately.  If you wanted to capture the Capitol Dome, I would suggest laser scanning, for capturing most situations Point to Point Laser Scanning (PPLT) should work just fine.  PKNail converts measurements directly into a Revit workstation-wirelessly, measure a wall that wall is entered into Revit, encounter a door, window, Fire Extinguisher Cabinet, sink, if you can measure it, it can be placed quickly and easily into the model.

Lastly, if the deliverable is 2D CAD, exporting views from Revit to AutoCAD sheets is a snap. Here’s a long winded Autodesk treatise on the subject or well, it looks like I will need to update with a screen capture video the quick process but the resulting CAD contains some of the meta information collected in 3D, such as 30″ Door, rather than creating anonymous objects.   Next post will follow in short order with a sneak peak of some of the features and the connectivity between Revit and a Leica Disto enabled by PointKnown surveying software.

Thanks for tolerating some self promotion.

BIM : Explode Value Engineering : #BIM #AIA #Revit

I am not an architect, nor do I play one on tv I simply have a small company that surveys buildings. While that may not qualify me to design one I have had the benefit of being in hundreds of buildings, surveyed them, see how they were put together, and they functioned with people in them, so with this little bit of information I feel qualified on commenting on architecture in general. And before I start I want to say that I believe architecture has the ability to transform and inspire like few other arts or disciplines because I can walk by a statue without noticing it (which I hope I don’t but were all in a hurry sometimes) but tougher still to ignore the building you are entering, or working in or even passing by, however, with that said I am unfortunately underwhelmed by most buildings I’ve been in or pass by, or have worked in. Too often we exist in a world that is value engineered, that is something has been designed to be produced as inexpensively as possible. I understand that, less expensively built; more people can afford to purchase; we all win, fine. Good in cars and televisions, unfortunate in buildings. We live in a center core, curtain wall efficiency that drains most of the fun, awe and art straight out of a building. And if you are trying to do something inexpensive, yet impressive this too can be a daunting task. But there are examples, artchitect turning shipping containers into homes comes to mind, like Adam Kalkin, Another is a home we surveyed designed by Carl Koch as part of community on Snake Hill. Now personally I thought it was fantastically ugly from the outside, looked like a box, seemed kind of cheap but as I entered the house, which still had all its original materials and finishes I was amazed how everything made sense, nothing wasted, coherent, took advantage of passive solar while providing lots of light and a great view, lines were simple, I was impressed but again this happens so seldom.

However, I have hope more and more architects are designing in 3D, even Architects who never once fired up CAD are embracing SketchUp as way to think and communicate in 3D. BIM allows design to happen digitally and with true BIM packages allows analysis and fabrication to build a building more cost effectively and real ROI metrics for making choices. Now this could be used for good rather than evil by providing hard bids on designs that were thought to cost prohibitive before, or proving new designs digitally and communicating them to developers and owners in 3D convinces them of their merit. What I hope is that ‘value engineering’ ceases to be a proxy for taking all the fun out out of a building but instead becomes part of the process that brings 3D digital design and BIM into reality and physical structures that continue to awe and inspire.

BIM As Built : Laser Technology

Speaking to a colleague from Europe who moved to the US because he stated, ‘there’s a survey shop on every corner in the UK, I could only find a handful here.’    However, that’s changing.  HDLS, high definition laser scanning is starting to take off, especially now that the GSA issued the laser scanning awards.  Additionally, more and more people are reworking existing assets / adaptive reuse projects so it is becoming more and more important to get the existing conditions data.  While everyone is waiting for the day we can walk around with a magic wand and wave it around the room we have to build a bridge from here to there.  HDLS in creating a 3D database is an excellent start.  I believe HDLS, from firms like Leica and FARO,  performs fantastically in certain circumstances such as inaccessible or difficult geometry, exposed MEP intensive projects, however, for typical conditions especially the interior of buildings it might be akin to using a sledgehammer rather when you need a fly swatter.   We, PointKnown, have been developing a product that bolts on to Revit and takes laser range finder data and builds objects as you measure.  This has been defined as PPLT (Point to Point Laser Technology).  It allows a surveyor to move quickly and accurately from room to room or object to object.  We do not intend for it to usurp laser scanning but rather augment current surveying teams, allowing them the most flexibility depending on the situation.

Most importantly is to define the deliverable and type of model needed for the project.  This can start at the basic architectural model using generic library items to, well , anything goes but most of our clients want dimensionally correct space and then they apply the material and details they need as that is what they want to control.

We are now accepting people and firms into our public beta that starts January 2010, if you have any interest please feel free to contact us at info@pointknown.com and put beta in the subject line.

Autodesk: User Upgrades : How many people actually do it : #BIM

I do not claim to be an analyst or play one on TV, however, I am interested in what is happening in this space from a business perspective and when I try to get clean answers on the question I am asking I find it is not always  easy.   So my most recent query was to find out how many people or percentage of users  actually upgrade?  Or start using the new stuff when it comes out.  As a software developer you want the needle pinned at 100%, as a user, I admit that I still fire up programs that have the ’05′ in the title.  Yeah that’s a long winded intro, but this is what pulled from Autodesk and my interpretation of it.

Using Autodesk FY 2010 as a guideline.

Combined q1 and q2

Total Revenue – $841 Million

License and Other Revenue – $477

Maintenance – $ 366

Upgrade – $70 Million

On a percentage basis Maintenance Revenue is at 44%, Upgrade Revenue is roughly 8%.

So at any one time at least 50% of Autodesk’s installed base is either using or has the opportunity to use the latest software.  I say the opportunity to use because if you are on a maintenance program that includes the latest releases it is highly unlikely that every organization would upgrade the software every year.  Rather they made a decision that it costs less to be on the maintenance program and have the upgrade option even if they only do it every other year, etc.  So sell it once and turn 1/2 your user base into an annuity.

I also know Autodesk has a lot of interest in creating the software sales model into subscription only, making that figure 100%.  However, that sounds a lot like putting a lot of bees in a jar and shaking it.  Better make sure that lid stays put.
