Owners Protective Errors and Omissions Insurance Coverage is a policy that provides coverage for the liability of a construction project owner for design negligence. These forms are written to be used as redundant coverage over a few basic policies that insure the various design professionals working on a given project (or group of projects). Unlike a project liability policy in which the various design professionals are the named insurers, the project owner is the named insured under E&O forms of owner protection.
