I don't believe that for a second unclejed.
Harmonics are powerful, but that 'little ticker' must have been DAMN big to shake a building, harmonic or not. Myth Busters did a piece on this with a several pound linear motor tuned to a real bridge's harmonic, they could detect it, but it wasn't bringing the bridge down. Something large enough to shake a building down would have had to have been hundreds of pounds, and the building design would have had to have been very primitive as well..
