I'm guessing they'll drive it up the slope (at the top of which sits the larger shovel), and then have the larger shovel sit on the sidewalk and in the street as it clears the rest of the basement level.
I'm told there'll be parking in the basement, retail at ground level, and offices above.
This shows the difference between a backhoe and a power shovel: a backhoe is designed to excavate below its level, while a shovel, like Mary Anne, is designed to excavate at the same level. (Can you tell I've read that book a lot in recent years?)
Another solution would be for the big backhoe to lift the little one out with a chain.
or they'll maintain a utility ramp, possibly out of view
a skilled backhoe operator can also make the damned things CLIMB...
here's an example of spidering: http://www.youtube.com/watch?v=PsKInuGbV5E
speaking of spidering, there's a whole class of spider excavators. crazy stuff: http://www.youtube.com/watch?v=Nqomz2j2-IQ
some of those things can also climb into railcars (with a frob), and i can't find the video, but i've seen someone who's VERY good, climb a ridiculous amount of stuff, in stages, 2x height at a go.
next time, we look into skidders and the specialty logging units they have now. cool stuff.
