Carlos Moncayo, a 22-year-old laborer from Queens, was trying to make a living as he worked on the construction of a Restoration Hardware store at 19 Ninth Ave. in Manhattan on April 6, 2015. Instead, his life ended that day when the 14-foot-deep trench in which he was working collapsed and buried him beneath tons of soil and debris.

An investigation by OSHA found that the project's general contractor, Harco Construction LLC of New York City, and Moncayo's employer, subcontractor Sky Materials Corp., of Maspeth and Calverton, did not provide cave-in protection* for the trench or support or brace a section of undermined and unsupported sidewalk to prevent it from collapsing into the trench.
