Cheaper than a failed job and an instrument that is not fully working!

If your changing scanner seriously look at the Leica and Cyclone - from your description of the site it would so simple to scan it, in loops covering the basement and all stairs with a very tight c2c registration.

How many scans are the stairs/basement?

Sure they are great but very unhandy because of the Size 😂.

The basement is about 250 Scans 😝. Great would be a smaller Version of the Trimble TX 8 or Leica p20.
X and y accuracy is good with nearly every kind of Laserscanner. IT is mostly the z value lacking. Because you only have the Floor and the ceiling for c2c connection

This is a non issue with a Leica scanner.

It might be heavy, but for something like this we use a tripod dolly. It is a lifesaver. You would have no problem registering this in Cyclone with a Leica scanner. And it would be perfectly level.

It's not that heavy, I reckon on average every 1 in 100 set ups you wish you had a smaller instrument or your going in something the size of a small house and you wish you had an RTC360... Then you get back to the desk and then data quality and registration are bang on!

As JeffT mentions, get the tripod on the dolley wheels and you massively increase scans per hour.

For large and historical buildings (which I have done a lot of in the UK) I'd recommend a P series from Leica. I currently use the Trimbles and they're ok, but you definitely get what you pay for.
