Move/Relocate Entire Revit Model Vertially in 'Z' Plane?

[Anonymous]

Hello, was hoping for some help solving this Revit model jam I got into... Happened when civil engineer changed their survey elevations on their final for-construction permit set drawing by ~ -80' me in the 11th hour of construction documents while I'm trying to get a permit set out. It's an unusual situation where we've been fast-tracking this and have had less meetings and coordination than normal which has caused this issue. I need to fix it asap but I've never encountered this sort of problem this late in a model building process where I have so many items pinned and have no idea how (or if possible) to move a project by a significant measure in the 'z' coordinate. I've moved buildings in the 'x' & 'y' plane using Manage/Position/Relocate Project etc, but I'm in over my depth with this one...

I've attached a screen shot where I have the Existing Conditions Site Plan dated 3/1/2016 (the middle plan on my screen shot) where you can see that the existing elevation for the prior house was listed at 104.26' and the site grading varied from 103.00' in the upper north-west side down to about 100.00' in the lower portion of the site.

These are elevation points that I built my Revit model on, which you can see correlated in the elevation mark numbers calling out the various site and building heights, floors and how they all interrelate.

Then they sent their new Proposed Site Plan drawing dated 9/20/2017 and you'll see that all the elevations are much different, off by about -80' (actually now that I'm comparing numbers plan-to-plan its ~79.47' variance) from the prior elevation points. The new proposed homes' first floor elevation they've adjusted to be about 25.60' (whereas I've been using 105.00'). So now I need to reset everything to correlate with the current survey elevation points

So... what is the best way to approach moving the project to these new elevation coordinates in the 'z' plane? If I try to edit/move one level at a time it will cause an error or break the model. I'm hoping there's a tool/command, work-around or macro I can run that I'm not yet aware of to solve these sorts of issues.

Thanks in advance!

Do not move your model.

Send Civil your latest model and have them establish and publish new shared coordinates to your file and send it back to you.  Then you can reload the updated Civil file without having to do anything.

Are you using your Survey Point? If not, move the SP down the eighty or so feet that you are off, and then change your levels' Reference Base to Survey Point. DO NOT MOVE THE MODEL.

As said above, do not use the Move tool to move the building in the z axis. 

It is simpler than you imagine. Just change the elevation of the clipped project base point of the architectural model. Assuming that the models of the other disciplines are already related to the architectural model, that´s all it takes.

That certainly sounds like a smooth fix, but this civil firm uses only AutoCad. So sounds like I'll have to unclip the project base point and reset as described below. I do appreciate your advice and will keep that in mind for future dealings with engineers using Revit.

Nice Ducati Monster btw!

Thank you

Not using the survey point as the civil firm is using autocad and the files aren't linked up. Sounds like I can use this point to reorient the project. I will try this, thank you.

Great I'm glad this sounds like an easy fix. I'll change the elev of the clipped project base point.

Thank you guys so much for the great responses. I've just backed everything up and will give this a whirl. Learned something new. Great forum.
