Without a front bag, my Brompton clocks in at about 28 lbs. I think the ultralight full size bikes are a bit lighter? I don't really have a good comparison, as the only other bike I've had recently is my GT hybrid which is 11 years old. As a full size bike, it seems comparable.
I will say that going up and down those stairs, a full size bike might have been a bit easier compared to an unfolded Brompton because the larger frame means the weight is a little distributed and so you can hoist it on your shoulder a bit easier (larger frame geometry). On the other hand, if you fold the Brompton up, it would be a more compact package to lift from one point. I didn't fold mine up because I didn't realize how many stairs I was facing...
