Illinois Statutes Chapter 225. Professions,Occupations and Business Operations § 340/5.5. Technical submissions

(a) As used in this Section, “technical submissions” include the designs, drawings, and specifications that establish the scope of the structural engineering project, the standard of quality for materials, workmanship, equipment, and construction systems, and the studies and other technical reports and calculations prepared in the course of the practice of structural engineering.

(b) All technical submissions intended for use related to services involving a structural engineer in the State of Illinois shall be prepared and administered in accordance with standards of reasonable professional skill and diligence. Care shall be taken to reflect the requirements of State statutes and, where applicable, county and municipal building ordinances in such submissions. In recognition that structural engineers are licensed for the protection of the public health, safety, and welfare, submissions shall be of such quality and scope, and be so administered, as to conform to professional standards.

(c) No officer, board, commission, or other public entity that receives technical submissions shall accept for filing or approval any technical submissions relating to services requiring the involvement of a structural engineer that do not bear the seal and signature of a structural engineer licensed under this Act.

(d) It is unlawful to affix one's seal to technical submissions if it masks the true identity of the person who actually exercised responsible control of the preparation of such work. A structural engineer who seals and signs technical submissions is not responsible for damage caused by subsequent changes to or uses of those technical submissions where the subsequent changes or uses, including changes or uses made by State or local governmental agencies, are not authorized or approved in writing by the structural engineer who originally sealed and signed the technical submissions.
