If you have built castles in the air, your work need not be lost; that is where they should be. Now put the foundations under them.
–Henry David Thoreau, Walden

Very often in New York City we are called upon to design ‘castles in the air’ in the form of additions atop already existing, usually masonry, structures and then, quite literally, design and build foundations under them to support the new additions.
