Gorgeous writing for the piano with adroit doubling (I'm guessing mallets but my ear is terrible for tuned percussion) for "sparkle." The march-like section transitioning to triangle/chimes and ribbony high strings, then contrasting call-and-response in winds (?), is a perfect setup for the building fanfare. This evokes an epic journey, with terrific deployment of the orchestra's sections weaving in and out and such versatile development.
