Demolish and rebuild floor

tonytwok — Wed, 01 Aug 2018 09:06:34 GMT

I need to rebuild one floor in different fases but I have problems. This is what I do: in the first phase I create the floor that I demolish in the second phase. In the second phase I create the new floor 100 cm higher compared to the old floor.

Now as you can see in my screenshots I have niches in the wall, how can I avoid this problem? Walls and floor are jointed and obviously I haven't this problem if are disjointed.

Have you tried switching the join order of the floors and wall?

Yes but isn't the right solution because in this case floor never penetrate until concrete structure.

Are the layers in your wall & floor set correctly?

Can you share an example project with the wall and floor in?

When you draw the boundary for your floor in plan, it doesn't need to overlap the concrete in the wall. If you do that then the gap shown in the next phase is smaller. I think you will then need to fill in the gap with a new small wall.

Technically what revit is showing here is correct, because that part of the wall never existed and needs a new piece to infill it.

.... got to phasing setting

... you can see the two floors attached

... click the upper floor and unjoin it

....

This is a good expedient but not a full solution because in one phase I see the floor not joined to the wall...

Yes; and you would have a "niche" in that wall in the real world as well. How would you deal with it? Probably fill it; right? Well then, fill it in Phase 2.

It maybe easier to create the finish layer as a separate wall. One existing, joined with the existing core wall and the existing floor, and being demolished. One new, joined with the existing core wall and the new floor.

Exist vs. New Construction. Floor removed AND wall repaired in New Construction.

How did you do this? I added a finish layer as a separate wall but if I joint it i have another time the niche.

Anyone know how he repaired the wall?

Re: Demolish and rebuild floor

barthbradley — Wed, 08 Aug 2018 14:39:22 GMT

How who? Me?

All I did was fill in the wall in the same phase I demo'ed the floor. I think I used an In-Place Component.

@tonytwok: I just looked at your Revit file that you attached above. It's Perfect! Just join the patch to the wall to remove the visible edges between the new and existing wall. Are you not able to join?

I don't know what I do yesterday but now I was able to joint correctly the patch! Thanks!
