PROFESSIONS AND OCCUPATIONS
(225 ILCS 325/) Professional Engineering Practice Act of 1989.

(m) "Professional engineer" means a person licensed under the laws of the State of Illinois to practice professional engineering.

(n) "Professional engineering" means 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.

(o) "Professional engineering practice" means the consultation on, conception, investigation, evaluation, planning, and design of, and selection of materials 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 shall be construed to practice or offer to practice professional engineering, within the meaning and intent of this Act, 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.

Examples of the practice of professional engineering include, but need not be limited to, transportation facilities and publicly owned utilities for a region or community, railroads, railways, highways, subways, canals, harbors, river improvements; land development; stormwater detention, retention, and conveyance, excluding structures defined under Section 5 of the Structural Engineering Practice Act of 1989 (225 ILCS 340/5); irrigation works; aircraft and airports; traffic engineering; waterworks, piping systems, sewers, sewage disposal works, storm sewer, sanitary sewer and water system modeling; 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 and rock classification, geology and geohydrology, incidental to the practice of professional engineering; geohydrological investigations, migration pathway analysis (including evaluation of building and site elements), soil and groundwater management zone analysis and design; energy analysis, environmental risk assessments, corrective action plans, design, remediation, protection plans and systems, hazardous waste mitigation and control, and environmental control or remediation systems; recognition, measurement, evaluation and control of environmental systems and emissions; control systems, evaluation and design of engineered barriers, excluding structures defined under Section 5 of the Structural Engineering Practice Act of 1989 (225 ILCS 340/5); modeling of pollutants in water, soil, and air; engineering surveys of sites, facilities, and topography specific to a design project, not including land boundary establishment; automated building management systems; control or remediation systems; computer controlled or integrated systems; automatic fire notification and suppression systems; investigation and assessment of indoor air inhalation exposures and design of abatement and remediation systems; or the provision of professional engineering site observation of the construction of works and engineering systems. In the performance of any of the foregoing functions, a licensee shall adhere to the standards of professional conduct enumerated in 68 Ill. Adm. Code 1380.300. Nothing contained in this Section imposes upon a person licensed under this Act the responsibility for the performance of any of the foregoing functions unless such person specifically contracts to provide it. Nothing in this Section shall preclude an employee from acting under the direct supervision or responsible charge of a licensed professional engineer.
