Dear Revit experts

I got a question from my managers, "How they can record and evaluate Revit productivity for commercial records." I have a lot of to say, but I don't know how to tell. 

We are a contracting company, before implementing BIM, they were measuring Autocad, as 3 sheets will be submitted each week by a Draftsman. Now, when Revit is on board, but sometimes we can't even submit a single sheet on some weeks because of coordination. With Autocad, we were submitting sheets without full coordination. 

But the question is, commercial manager asked that if there is benefit from Revit over Autocad then advise him how to record it for commercial evaluation. In business, there must be proper explanation for everything for final, annual audit. 

I am looking around to get a proper answer, if any of you have solved similar issues, please share your view.

I'd still do my best to measure it by sheets.

You can't compare apples with oranges. They are too different.

In AutoCAD you arrange dumb lines in plan, section or elevation to fill sheets. You work to fill the sheet.

In Revit, you keep arranging intelligent 3D objects in 3D geometric space and populate them with data to form database schedules. You can't generate a sheet until the 3D model is completed and for sheets that required schedules ( like door schedules), you can't finish them until the data is loaded into the the 3D objects.Revit requires a whole lot more time up front for 3D modelling. A lot more than AutoCAD. So the highest workload peak happens much earlier during the design stages rather than the documentation stages. You need to tell your bosses to push the resources forward in the programme. The bulk of the work is done earlier. During documentation it takes a lot less work as the work is done in the 3d modelling stage. In fact with skilled Revit users and good templates you save up to 30% overall resource in an average project. You save up to 50% in repetitive projects like franchises etc.You can't cheat in 3D by ignoring the less important elevations. Everything must be modelled. You can't cheat in 3D by just using the fat edge of the pencil to make lines meet. It has to be modelled accurately.

So more time is needed up front.

Oh and if you try to save time by drawing 2D during the design stage to meet deadlines then you are only going to have to model it later in 3D which means you will model it later and take more time overall as you are modelling the project twice.

The values in BIM are hidden in performance. Value in resolving clashes on the computer not once they are built.Value in 3D visualisations ensuring that all project team members know the full story at the end of each meeting.Value in less RFIs, so less paperwork and running arounf.Value inreducing variations, so less risk.Value in more accurate costings and overall project confidence.

Have a read of these and good luck.http://www.shoegnome.com/2015/12/09/bim-still-bankrupting-firm/https://www.linkedin.com/pulse/burdensome-bim-budget-morrow-brady-plansortcom-morrow-brady

i agree.

the question is how you are going to document the benefit , so that it will be easy to answer an investor of the company about why he want to buy Revit

You can read and talk to others about their experiences.  Beyond that, this is different for every office dependent on practice standards, goals, their personnel and the dedication of management.
