Using Revit, Sketchup - the Archtiect and the GCCC Contracts

Using Revit, Sketchup - the Archtiect and the GCCC Contracts

Postby onq » Sat Aug 13, 2011 12:48 pm

I've completed all the modules in Part 1 and Part 2 of the course in 3D Revit offered by Paradigm http://www.paradigm.ie/ it was impressive but much harder to "get into" than SKetchup and very much a "drawing from the code-up" program.

Once the basics were decided, you could run up a very impressive model of a building in relatively short order, but you had to detail as you go.

I don't mean *think* about the details to know what you should be doing at a certain junctions - it failed that test because many of them will be once off regarkess - the nitty-gritty still gets done "by hand".

Unlike Sketchup, where you can paint alternative materials very easily, with Revit you have to specify every material and thickness just to get a model up, as in specify materials thicknesses and build up for every material.

As for the components like windows, while many are pre-loaded (with insulation/vcavity fire-seals adhering to the sides of them, no less), any variation means you have to go into the component and detail the changes.

---------------------------------

Then there's the surface modelling issues. Basic forms are fine but even to introduce a string course you have to fo into your wall specification and re-write it, specifying "sweeps" (the deviations from the norm) so you can put in string course or whatever.

With Sketchup you can draw a line, pull the face out 25mm and paint it in the material of your choice.

So the point at which AutoCAD 3D Revit becomes productive it seems to be further down the design process than Google Sketchup, which can be used to start a design in, its so simple to use.

---------------------------------

And CHEAP! Did I forget that?

Granted its still in development, it has a fantastic user base and several competent people giving courses in it like Paul Lee down in Cork.

Looking at buying it from the official site, Sketchup cost €360.
No, there isn't a "nought" missing. Three hundred and sixty Euro!

Last time I checked Revit cost €5,000+ - five thousand Euro plus!

Plus Sketchup will run on almost anything - my Win2K SP4 1.8Ghz Pentium 4 laptop with 500Mb RAM and a 500Mb Ati Radeon Card runs it. A Dell Optiplex GX745 i.6Ghx with 2Gb Ram runs it.

AutoCAD Revit needs a fairly heavy specification to run, because its not just rotating surfaces with painted materials, its rotating a 3D model of the bricks and mortar.

---------------------------------

Revit seems intended to replace both the Architectural Technician AND the Quantity Surveyor, per the demotion of the Bill of Quantities in the GCCC contract, and the supplanting of both the Architect and Architectural Technician by Architectural Technologists in the building process.

For people intending to accept becoming sidelined on GCCC contracts in favour of the Clients Agent, that might be seen as a good way to go, to try to maintain what little authority the architect has left and keep it all in-house.

If that's an acceptable strategy - and it achieves its aim, the cost of the license and the training of the operator might be justified - so long as he/she was tied to your office to get the investment back out.

---------------------------------

I personally think its the wrong way to go. I think that strategy reduces the design team, reduces the specialist knowledge available and makes it less reliable overall and certainly means that the finger is easier to point.

I think it undermines the place and authority of the architect in an attempt to transfer all risk to the contractor, a sea change in contract law that I look forward to seeing tested in court.

But I suspect the GCCC contracts and their derivative will have their day and then settle down alongside the RIAI Contract or JCT and FIDIC- style imports.

---------------------------------

Hows' THAT for a Saturday before lunch! LOL!

(hmm, I must post that on Archiseek for the boys to mull over)

Drawing board,pens,tracing paper = priceless (a lot cheaper than revit) might create jobs too but wait we have the internet.

Archicad and revit and normally reserved for medium/large practices most small operators might struggle to make use of a license on small projects..
