Building Information Modeling (BIM) updates

BIM news & updates

“Information” as in BIM and its application !!

There has been a lot of discussion about the fact that Information is still not used to give complete advantage BIM offers to its user. 

Out here I would like this group to provide their feedback as to how they have been successful in implementing and inserting maximum amount of useful information in the building model. 

To me a building model is completely successful if the same model contains so much of information that the same can be used for facility management after the actual construction is over. Till date we have not reached such a level where our models can be used for FM. 

What is the optimum level of information we should put in the model which can used for construction process!! With all manufacturer building their library in Revit, I foresee much more information being assembled into a model. 

Let us try and attempt if we can understand the “information” as in BIM really.

The above was posted by me on linkedin and I got some response which are as follows:

First of all I would add that the BIM model is useful both in the projecting and construction phase AND as a database after the construction process.To find the optimum level of information in each project I think you must define the ambitions of each disiplin and check the possibilities of their software tools. <br/>
<br/>
In Scandinavia many libraries are made for ArchiCAD which is also able to communicate very well with applications like Tekla, Magicad, DDS etc. I thing the question about converting data via IFC is maybe more important than asking manufacturers for rich libraries just now.

It’s a very interesting question being raised here. 

We all been listening to how much information we can put into a BIM model, and this is – to some extend – possible with today’s technology and tools. 
And the truth is that if you look at the entire building life cycle most of this information is needed at some point! 

But it isn’t just a question of how much information you can put into a model. It’s rather a question of who has this information and who puts it into the model. 

An architect won’t use his resources to enrich a BIM-model unless this gives him added value. Unless specified by the client he won’t enrich with data needed for FM, as he doesn’t have the need for this data. 

What we see today is a lot of offices and professions using BIM-tools, but just for their own needs. 
I think we need to move beyond this, but I’m not sure how this is done. 
One way is for the client to make demands to the use of BIM and amount of information in the very beginning of the planning process when contracts are signed. 
An other way is a better understanding of the different needs for information in different professions and the value correct information at the correct time can ad. The problem is still that if the person that is supposed to add information don’t see the value, he won’t use his resources on that! 
Finally there is the situation where people add the information needed for others without knowing it or using resources on it. This could be the situation when manufacturers gets consistent libraries. Then an architect would add a window and the information needed by the engineer or the contractor would automatically be added. There are some examples of this being possible, but its a long way still. And we still haven’t solved the problem of someone (the manufacturer) paying for someone else benefit (everyone else)!

I work in the Autodesk Content Solutions group where we are actively working to help with this issue from the front end of the project. We assist manufacturers in the getting their BIM models built, and are working with different roles in the industry to help define what information is necessary/desired by the various roles. <br/>
One thing that this conversation (this blog commentary) points out is that EACH role uses BIM differently and sees BIM differently–owner, architect, engineer, manufacturer, facility manager. <br/>
Autodesk Seek (
 http://seek.autodesk.com/ ) is a resource for the entire community to find 2D, 3D, BIM, specifications, msds sheets, product brochures, etc. Users will find Autodesk, Graphisoft, Bentley, and SketchUp files along with word docs and pdfs, in an effort to serve the consumers of this data as best as possible. <br/>
What the manufacturers need is to hear from the consumers of this info (Archs, Engineers, GC’s, Facility Managers) that they NEED their info in BIM formats!

i think it makes sense to look at the end game and work the project lifecycle in reverse to define the scope. most owners will not know the right questions to ask for years to come. it will be the design professionals responsibility to guide the owner through this new process. 

will the building be managed by FM? (construction models) 
will the project be built full BIM? (construction models) 
will TCO studies be required? (energy models) 
should the entire design team utilize BIM? (design models) 

this seems to be a work in progress for us but one thing is important to know; these models are not created equal: 
the energy models could be the design models but not when ‘what if’ scenarios are run as this weights down the design models performance. the construction models are the contractors interpretation of the design models and are usually updated through construction. information required in the construction models (temp. bracing, conc. pour phases, etc.) would not reside in the design models. 

when the expectations are know completely, the information required is understood. just like understanding a buildings use helps the team build the building, understanding the models use helps the team build the models.
