Tried again. Looked at import Options this time. I’d used the defaults before, which had units Feet, but all other options unchecked (Preserve origin, merge coplanar faces, and orient faces consistently).
I checked the last two, but left Preserve origin unchecked.
Got these results:

There’s a couple of groups of stray edges on the left side of the import. Removing those makes Zoom Extents get close round the meaningful content of drawing. Everything is on the z=0 plane - no 3D elements - and there are no faces, and no components.
I suspect the units are not Feet. In one area there’s something that looks like a door, but it is well over 1000ft wide! That might make sense if the units should be mm.
Trying a third time, changing units to mm.
Makes more sense this time. All layers are on, and there seems to be no hidden geometry.
Deleted stray edges, zoomed extents again, and things look better. But it’s hundreds of metres off origin. Relocated the whole drawing close to origin, and saved. Here’s the result as a 2016 SKP file. Uncompressed, it’s too big to upload here, so I’ve zipped it.

I have no idea whether the TECLA software import DWG plugin would work better than Jim’s DXF import, but the latter would need you to convert the DWG file first to DXF, for which you could use the Teigha File Converter.
Try both to see, unless someone else on the forum can offer experienced advice.
