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 Projects Coming in 10% Lower –> IPD 20% Lower

A recent post by Dennis Neeley on Reed Construction Data states that recent reports show projects coming in at 10% for building drafted in a BIM format, and 20% lower for those using IPD and integrating the disciplines digitally.  However, Dennis goes on later on in the article to note, and rightly so, that operating costs of a building during its lifetime start to dwarf the construction costs.  And that correct data about existing facilities and the better management of those assets can show savings from 20% to 40%.  However, still one of the biggest issues, and one I touch on frequently,  is interoperability, the development of standards and standardized objects.  I also think there is an opportunity for manufacturers who provide excellent objects to designers can start see quicker adoption of there products and decreased sales cycles as consumers of those digital objects are already educated about the product and using them in their models.

Capturing Existing Building Conditions Accurately and Efficiently

“Capturing existing building conditions accurately and efficiently is one of the keys to success for a renovation project.”   That’s straight from the Autodesk video.

However, when they go over the methods for documenting existing conditions…

Existing Conditions Methods

Autodesk Existing Condition Methods

I’d like to add PKNail, because I would argue that it’s tough to be accurate without measuring something.  Sure that’s a bit self serving, but we’ve all been there, dragging lines, using different colored pens, sketching with gloves on, or trying to use a laptop in the field, and we are fired up for the release, because it works, it’s making our job easier, we’re quicker, more accurate, and building Revit models in the field.   measure –>press –>model and were eager to get it into everyone’s hands.

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.

Squirelly Times Call for BIM: #BIM

Yeah I called them squirelly.   I have  to say Q4 2009 has been better than the rest of them bit I am finding, and getting anecdotes from others in the industry that it is the squirelliest of times, and I’ll try and stop using that.  What do I mean?  I’ve put together more proposals this quarter but am finding that clients are cost conscious to the extreme, and no matter the relationships and reputation you have built up it’s more what have you done for me lately.   Now while its tough environment when someone is out there ready to cut you off at the knees on a bid just to keep busy on an unfortunate race to the bottom what can we do to keep business, get new business and offer our clients more of an incentive to stay with us and or pick up new ones.  In most cases, a BIM enabled firm will be able to offer more services and accurate bids.  A recent article in Construction Week outlined Better Bidding Through Bim. Better bids, better scheduling, projects on time and on budget, proven ROI all make a more persuasive argument.

While economists may argue that this resetting of the market is an efficient allocation of resources and our new reality, it’s time then to efficiently allocate our own.

Vela Systems and Tekla : Utilizing Field BIM

While one might argue what entails Field BIM Vela released a case study where they integrated their process on top of Tekla’s BIM.  DPR Construction replaced all their paper logging and tracking systems with VELA’s field software for digital tracking, specifically the doors and frames.  Inventory was tracked the entire way through delivery and installation, plus deliveries could be checked for completeness and damaged products.  All this information was then made available in real time to all parties.

#MassTLC Unconference : Part Deux

So this was my second time at the unconference, this was with a different focus though from the on e in the spring,  Entrepreneurship and Innovation.  What the unconference does is to increase your chances of serendipty.   I hear you saying, “what kind of drivel is that, you sap.” And rightly so but give me a minute.  We have all had those moments whether you  are an entrepreneur or selling insurance or designing a product that you meet someone or speak to someone and they either give you an idea, or a lead, or some help that either, at worst makes your day, or better gets you a sale  or starts a business relationship and you just don’t know sometimes where that is going to happen.

So you’re on the grind going to conferences and tradeshows, presentations, lunch and learns, etc. and man is it a slog sometimes.  At the unconference, because of the tenor and how it was set up, people are there to connect, some are still better than others and it is such an amalgamation of talent that the chance of hooking up with someone who gets what you are talking about, or has useful advice or wants to hook you up with someone who could help is greater than at any conference I have been to. So get your game on and giddy up.

This post was from Don Dodge from one of the session and lists a host of resources in Mass for entrepreneurs.

GSA Awards BIM IDIQ: #BIM #GSA

The GSA announced the awards for the BIM IDIQ.  I am still trying to unearth the complete announcement but one of them is HNTB Federal along with its team of subcontractors which were awarded all the zones.  As I find out more information I will update the post and announcements.  Still don’t know how many firms were awarded which zones, etc.
