Project management professional liability (PMPL) insurance was developed to remedy some perceived problems with additional insured status and owners and contractors protective (OCP) liability insurance. It provides coverage for vicarious liability of the owner, primary architect and prime contractor as well as the contractor's general supervision of the project.
The endorsement was intended to fill a need created by an optional requirement in the 1997 edition of the General Conditions for the Construction Contract published by the American Institute of Architects. The concept never gained traction and was withdrawn when the A201 standard contract form was updated in 2007. The standard PMPL endorsement was subsequently withdrawn.
