Quantity Takeoff using Revit

Anonymous — Mon, 21 Dec 2015 07:53:25 GMT

Hi all,

This maybe a generic question. I will be working as an estimator at my new job. I am pretty good with revit's material takeoffs. BUt what specifically should I look into when it come to performing it in a job? Are there any pointers which you can suggest from your experiences? Is automation required or is it worth it (using Dynamo)? Please provide me your inputs!

Thanks!

If you are already feeling comfortable with material take-offs and you are also Ok with normal quantity schedules you are on your way.

Of course it will depend on the quality of their Revit projects how easy it wil be. Depending on the size of the company (specialists working on Revit) it might be good if you have knowledge about family creation. This will enable you modify/create families to streamline data for estimation.

Dynamo definitely is an advantage. As Revit is limited in the scheudling and calculation. So manipulating data (e.g. import/export) with Dynamo will give you lots of extra possibilities.

@L.Maas Thanks for your inputs. By nany chance do you have a material or best practices for qunatity takeoffs. I know how to do it, but I think there could be better ways. If am not asking too much, from your experience can you list some of the defeciencies or difficulties you found out during estimating on revit? I can build upon that and create dynamo codes. Thanks again for your reply!

Revit sheduling and calculation capacities are somewhat limited.

In my situation, we have made (almost) all our families ourselves. With that we have added several shared parameters needed for estimation.

Among those are several to be able to do grouping of material.

We use dynamo to push out information for further calculation.

Depending our project needs we pull some of the data back into revit.
