Why would the world be a better place to live when use "BIM?

[Anonymous]

After years of working with calculate quantity of materials, produce detailed models, and so on, I really can't find why we should put all the information about a building in our cadsystem.

I can se why a wall, beams, columns are the right thing with right parameters in it because of communications with constructionsoftware.

When does we overworked our buildings because of this "new BIM" talk like a god from heaven?

I think BIM is enough most of time when we could have ID and dimensions from our buildingobjects, but this has many cadsoftware problems to give us, but they could give us an option to include model, price and so on... DOH!
It's not hard to calculate the quantity of 10 doors of different types manually, but it's hard to calculate the quantity of gypsym..

i understand what your concern is and discussion is good too.

1. BIM software is only for drawings and modeling with information which make the drawings and models coordinates each others. First, it reduce some kind of mistakes.

2. the IFC model which produced by BIM software which can be recognized by third parties software. then those softwares can analysis the model for us. it is unwise to only produce dwg and pdf .....

BIM can not sure 100% accuracy, but at least, it has more intelligence than the 2D and 3D CAD before.

BIM can not reduce our working time, but at least, it won't waste our working time in 2D and 3D CAD before.

think some questions:
1. architects hope to see more sections for presenting the inside of the building, if you are a draughtsman, do you love to draw 5 sections and a 3D model?

2. are you sure you can draw them accurately in 2D/3D CAD?

3. what if the architect change the design all the time?

4. still love to use 2D/3D CAD?

Why is VB (BIM) better?

It coordinates. Depending on the software, it also talks to structural, MEP, energy calcs software. The main advantage? The computers know what is what. Human interpretation is not necessary. You can build the building in the virtual space, test it to earthquake, wind, whatever. Cost benefit is immense, especially if the BIM model is good enough to cover not only the design and the approvals, but the construction and the building lifetime.

Why is it not?

CAD mimics the way of doing things for centuries, therefore no new workflows, no new knowledge (knowing five commands of anyCAD is enough - line, erase, text - to produce a drawing) is necessary, no new hierarchies are established, the business is as usual. VB (BIM) puts all of this on the head - the architects are in charge again, the computer illiterate principals are threatened, the large companies can't flog the draughtsmen into submission ... horror! The ones above are not in control any more, the ones below have to keep on learning. Not in human nature, that tends to inertia.

Optimistic, huh?

True... But my idea of this thread wasn't about how I should do, more about how the world looks at "BIM"....

IMHO right now the world of BIM/VB is pretty much limited to a small part of the world of design & construction. Even there, there is more buzz than reality. So I'm with Tom, it's a waste to to put in extra information if it doesn't benefit you. But that benefit can be as far a field as doing it to learn how to do it. Or to show a client it can be done.

But when you ask, "How the world could or would be a better place if BIM/VB was the norm?" you quickly move into dreamworld. The world where all that information does have value.....and you get paid a premium to put it in.

That is the world where the virtual building lives along side the real building, interacts with it. Where the light switch on the wall connects, not just with the light switch in the model, indicating whether is on or off, but also links to the exact model of the switch on the manufacturers website so you can order a replacement. etcetera etc.......

Someday over the rainbow........

Which in part is why we bother.

Hi all, this is my first post.

I think I understand BIM, but what's the software? Is Archicad BIM?
I use AC 12 and I model almost everything and take all my sections & elevations from the model. Isn't this BIM?

Is it just a case of this been taken further and entering more information about each element?
Are there BIM add ons for AC 12 or can it all be done within AC12

[ares997]

BIM is a process by which we can give objects within a model properties (ie weight demensions model# and host of other things). Though archicad has that ability you have to break the Geometric design progression of the model between the designer, consultants, builders, at this time so you need more than #ac12 to be a sole BIM practitioner. Ac13 is a step closer to a one stop shop for BIM.

Hi,

BIM for some big developers' in today's (USA) market means that they think the Architects construction drawings should be detailed and thorough enough to replace shop drawings. Not my cup of tea. Mixing "means and methods" with design intent gives me schizophrenia.

Complete integration of the 3d model and design drawings that mimic a traditional construction drawing in a bi-directional work flow is what I want out of BIM.

AC-12 for its many faults does a fabulous job of providing a platform for this effort. I own Bentley's V8 Microstation, Triforma and Architecture platforms, but without a dedicated IT department or very technical person in house, it is not user friendly (and non-returnable). As a sole practitioner, AC-12 is my ticket.

PS In the last two years I also bought and returned DataCad, Chief Architect and SoftPlan, and still AC is my preferred choice. Just my opinion of course.
FYI, I design new houses, renovations and small commercial buildings.
