The struggle is to link costs to quantity without going back to the system of lists as described by Godi. That takes quite some time to setup.
For our projects we use a spreadsheet for cost calculation and I use schedules to get quantities for certain things. Some things I don't model (trim mostly) and I just calculate that with the numbers I've put in the spreadsheet for the most part. Depending on the size of the project I ussually have a cost calculation done in a day or two. These are quite detailed though. Initial estimates we just go for gross volume multiplied by expected level of luxury.
I don’t know in other places but in our country every architecture office uses specialized applications to make cost estimation.
The only think we need from the architecture design app is a detailed quantities list of every material or works with a reference to link it with a particular budget item in the database of that specialized application.
In Archicad that list can, at least in the present moment, be obtained only with the properties system. You need some preliminar work, is true, but once it is done you have it ready for all your future projects. When every 3D build design finished you can have his quantities list in seconds
