In this article by the Las Vegas Sun about the dispute between Perini and MGM Mirage <a href="http://http://www.lasvegassun.com/news/2010/may/20/condo-owners-enter-dispute-between-mgm-mirage-peri/">New group enters dispute between MGM Mirage, Perini</a>  The developer of another Perini building project is claiming that Perini used "sophisticated wiping programs to sanitize its project server and project computers after it was ordered by the District Court to preserve all project records."  Whether this occurred or not is up to the courts to decide.  The risk of this occurring should cause every owner who says "we let the contractors take care of managing project information on our capital projects" to reconsider their approach.  Even if a contractor does this on a project and is found guilty the information is still lost and can not be recovered.  Every owner should implement project management applications that track and control project information assuming the worst case scena. To protect yourself even more you should implement a system from a trusted 3rd party to guarantee that no on the project can modify or delete records pertaining your projects.
