They are already replacing the sidewalk on a route I frequent even though they just built it last year. I saw workers doing measurements and taking photographs. Apparently, whoever built it did not pour the concrete thick enough. So it cracks whenever it has to support something heavy. I’m not sure whether it was an accident or deliberate; but I hope the city gets their money back. It would have been less of a nuisance for everyone involved if it was done properly the first time.
