Hello Everyone,

We are doing our first project in Revit and we are planning to use this model to generate as accurate as possible Bill of Quantities(atleast for the Brick work and civil work)

I was wondering what are the best practices for creating a model to extract BOQ? Like joining, cutting, order of joining etc?

What are the best practices you follow?

Hoping to have a good discussion.

Thanks

No matter what quantities you get, you do understand that you still have to account for waste?

If you have modeled correctly, you can use a material schedule to get quantities.  There are some things that you have to account for with your materials.  For instance, a stud wall and a stud wall with insulation.  Revit will give you wall area but you have to use your own formula's to determine studs and you need to describe stud walls differently than stud with insulation.

Revit is not setup out of the box for this.  Use material parameters and schedules to get what you need.  A typical one I use to get sheets of plywood or drywall is to create a calculated value that uses the material, e.g. plywood material area/32 to get how many 4'x'8 sheets there are.  As WW has mentioned, you also need to factor in waste in there, which can be an adjustment to the calc. formula, or done in post woith excel or manually.
