In this article by the Las Vegas Sun about the dispute between Perini and MGM Mirage <a href="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 question every owner should ask is "am I tracking all this information myself?" All too often private and public owners say "we let the contractors take care of managing project information on our projects".  This is is obviously a recipe for disaster, even if a contractor does this on a construction 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 scenario will occur. To protect yourself even more you should implement a system from a trusted 3rd party to guarantee that no one on the project can modify or delete records pertaining your projects. Systems like EADOC's construction project management application do not allow any users to edit the database, this is where all the records are stored ensuring complete and accurate records of everything that occurred on the project.
