Calculate construction volume

How can I calculate my building volume with Revit LT?

PS: Mass in place is not available in Revit LT.

Create a room or space bounding by the exterior walls and roof. Set room computations to area+volume.

Thank you for your suggestion. However, what do you mean by 'space bounding'? Excuse me my revit knowledge is limited.

Analyze tab is also not avaible in Revit LT.

Just use room then.

Set room computations to area + volum
Create one exterior phase and one interior phase
Move exterior walls and roofs to exterior phase
Add a room under exterior phase, set limit offset to above the highest point of the building then you have a room with the volume of the building

Does this method also work for complicated shapes?

What about just totaling Volumes in Schedule?

BTW: You could get there by tracing the exterior face of exterior walls with Room Separation Lines and creating rooms bounded by these Room Separation Lines. You would do this in a Phase BEFORE construction with View Phase Filter set to "none". Room Separation Lines have Phase Created/Phase Demo'ed just like Walls, Floors, etc. So, you would demo them in the subsequent Phase where the construction begins.

You need to define what volume you need and for what purpose. Some possibilities:

- total volume to determine if a professional has to stamp the design : this would include the total volume measured from outside of enclosure and includes volumes of walls, floors (it isn't just the actual room volume)

- volume of rooms only (this would exclude volume of walls etc. and the above mentioned room schedule should work)

- include or exclude plenum and other intentional voids like shafts in a building?

Without knowing what volume you need and for what, it is hard to answer how to get the correct number. Same goes for area calculations where walls and void spaces could be included or excluded.

Edit: there seems to be a website issue preventing me to have space between paragraphs

Thank you for your contribution. However, I am looking for the volume with exterior walls and roof included.

I need the total volume so that the official can approve the project. This include the total volume measured from the outside. Including volumes of walls, floors and the actual rooms.

Then get them from wall/roof schedule and add them to the result of the room volume to get the total volume.
