Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

225 ILCS 340/5

    (225 ILCS 340/5) (from Ch. 111, par. 6605)
    (Section scheduled to be repealed on January 1, 2030)
    Sec. 5. Practice of structural engineering. A person shall be regarded as practicing structural engineering within the meaning of this Act who is engaged in the design, analysis, or supervision of the construction, enlargement or alteration of structures, or any part thereof, for others, to be constructed by persons other than himself or herself. Structures within the meaning of this Act are all structures having as essential features foundations, columns, girders, trusses, arches or beams, with or without other parts, and in which safe design and construction require that loads and stresses must be computed and the size and strength of parts determined by mathematical calculations based upon scientific principles and engineering data. Nothing in this Section imposes upon a person licensed under this Act the responsibility for the performance of any acts or practice unless such person specifically contracts to provide it. Nothing in this Section precludes an employee from acting under the direct supervision or responsible charge of a licensed structural engineer.
