In this Sept. 17, 2018 photo, a man wields a pickaxe atop a fourth-story wall, as workers demolish a government office building which was catastrophically damaged in last year's 7.1 magnitude quake, in central Mexico City. What little progress has been made in demolishing buildings seems to have come from the unsung heroes: demolition workers who break down the upper floors of buildings too tall to use heavy machinery.
