I went to the site of a development project that intends to turn a half a block of vacant land into condos. Still in their early stages, I noticed they had recently begun the process of sectioning off the site for what I assumed to be marking the layout/foundation for building . They had installed a series of rebarb posts in the ground connected by strings, so I cut all the strings and removed all of the posts from the ground (minus 2 stubborn ones). The beams were pretty heavy so I threw them in a nearby dumpster burried under trash.
Hope they’re mad when they realize all the work they did was for nothing.
