I think that the accuracy of anything from a 3D model is something that should always be of the highest priority in BIM. Whether it's materials, dimensions, site location, asset management, visualization, etc. if the model is not accurate then the value of the model starts to depreciate. Once that occurs, there's not much worth in investing the time to convince people that this is the direction to go when the source material is at fault.

There are so many different software that I have looked at to get quantification. They are all able to provide amazing information! They really are amazing products, but in the end I am always cleaning up a Revit model in order to get some decent information to our estimators.

I've worked on both sides of the fence with Architecture and now Construction. The information that Architects and Engineers are striving for in their Revit model are not entirely the same things that Contractors strive for. We use the same software, but for different reasons.

There are a million and one reasons why a Revit model is not 100% finished, but I think it mostly comes down to time, schedules, changes, and money.

Long story short, the more collaboration between all parties will allow for a more accurate model. When all team members strive for the same goal and are truly a team, then I think the model will ultimately reveal the fruits of that labor.

It may be wishful thinking, but it's something to strive for...
