Contract Documents: The Plans and Specifications show the extent of the Contract requirements. Generally, most scope of work items appear both in the Drawings and Specifications. However, if a certain scope of work item only appears either in the Contract Drawings or Contract Specifications, it will not be an excuse or argument on the part of a Contractor that the scope of work is not adequately defined. Therefore, if any work is singularly shown in either the Contract Drawings or Contract Specifications, then that item will be a contractual responsibility of the contractor involved. 4.
