First, apologies that this isn't traditional HN news [I guess reader's votes will decide whether this is interesting to some extent], but there was recent discussion here about how market forces could help enforce good building practices - http://news.ycombinator.com/item?id=1159827
In that context, I think this is interesting: reporting on which constructors are responsible for the worst damaged buildings. I received this link by email, and it seems to be going viral here in Chile - http://ciperchile.cl/2010/03/06/estas-son-las-constructoras-e-inmobiliarias-de-los-edificios-mas-danados-en-santiago/
