Material Takeoff Schedule Content Consistency

[AdvancedCM]

Relatively new to Revit material content for quantity and cost estimating. When creating a material takeoff schedule, structural steel elements are fairly straightforward, but other materials seem to be more difficult to calculate weights. For example ¼” diamond plate on a structural steel mezzanine doesn’t seem to have a Material: Unit weight field value in the schedule. There doesn’t appear to be a place in the family to contain or calculate a weight so on the schedule the value is zero.

This limits the ability to simply generate a total weight of these materials. In general it seems like field data for quantity estimating is inconsistent between families (or doesn't exist at all).

Any suggestions?

you can add calculated value based on the volume or area&thickness. Then mulitply by a manual denisty value or add another field for structural density as specified in your material:

Having the function feature is nice however part of the problem is that there isn’t a field for mass/weight in the diamond plate family. So to calculate a weight I would have to create a custom field. Keep in mind as an estimator I receive the Revit file from designers so I don’t want to have to enter manual data every time a file revision is issued.

Looks like there isn't a simple solution to generate consistent takeoff reports.

I guess if the element doesn't contain mass/weight or density, and you dont want to add this manually in calculated formula, then your only option is to ask whoever did the model to add physical properties to all elements that are not defined.
