Illinois LLC for Engineers Law

Limited Liability Company – General – Illinois

In the State of Illinois, there are several organizational choices for the rendition of professional services: a Professional Service Corporation, a Professional Association, and a Limited Liability Company.

With certain restrictions that are inapplicable to professional engineers, a limited liability company (LLC) may be formed for any lawful purpose or business.

A LLC organized to engage in the practice of professional engineering is subject to the provisions of the Illinois Limited Liability Company Act and the Illinois Professional Engineer Practice Act. Additionally, that LLC is subject to the rules and regulations of the Illinois State Board of Professional Engineers.

A “professional engineer” is a person licensed under the laws of the State of Illinois to practice professional engineering. “Professional engineering” is the application of science to the design of engineering systems and facilities using the knowledge, skills, ability and professional judgment developed through professional engineering education, training and experience.

A “professional engineering practice” includes consultation on, conception, investigation, evaluation, planning, and design of, and selection of materials and methods to be used in, administration of construction contracts for, or site observation of an engineering system or facility, where such consultation, conception, investigation, evaluation, planning, design, selection, administration, or observation requires extensive knowledge of engineering laws, formulae, materials, practice, and construction methods.

A person is considered to practice or offer to practice professional who practices, or who, by verbal claim, sign, advertisement, letterhead, card, or any other way, is represented to be a professional engineer, or through the use of the initials “P.E.” or the title “engineer” or any of its derivations or some other title implies licensure as a professional engineer, or holds himself out as able to perform any service which is recognized as professional engineering practice.

The practice of professional engineering includes, but is not limited to, transportation facilities and publicly owned utilities for a region or community, railroads, railways, highways, subways, canals, harbors, river improvements; irrigation works; aircraft, airports and landing fields; waterworks, piping systems and appurtenances, sewers, sewage disposal works; plants for the generation of power; devices for the utilization of power; boilers; refrigeration plants, air conditioning systems and plants; heating systems and plants; plants for the transmission or distribution of power; electrical plants which produce, transmit, distribute, or utilize electrical energy; works for the extraction of minerals from the earth; plants for the refining, alloying or treating of metals; chemical works and industrial plants involving the use of chemicals and chemical processes; plants for the production, conversion, or utilization of nuclear, chemical, or radiant energy; forensic engineering, geotechnical engineering including, subsurface investigations; soil classification, geology and geohydrology, incidental to the practice of professional engineering; energy analysis, environmental design, hazardous waste mitigation and control; recognition, measurement, evaluation and control of environmental systems and emissions; automated building management systems; or the provision of professional engineering site observation of the construction of works and engineering systems.

For the purposes of the Professional Engineer Practice Act, the term “registered” means the same as “licensed.”
