Ethics is integral to all decisions, designs, and services performed by civil engineers. Not only the public trust but also their lives, safety, and welfare depend on professional engineers' efficient, safe, and economical performance of their duties. ASCE's ethics programs, policies, and resources are designed to assist its members in understanding their ethical obligations and incorporating them into the day-to-day conduct of their professional and business-related affairs.

1 This Code does not establish a standard of care, nor should it be interpreted as such.
Under ASCE bylaws, all ASCE members are required to comply with the Code of Ethics and to report any observed violations. The Committee on Professional Conduct (CPC) reviews and investigates complaints in accordance with its rules of procedure. If the CPC finds that an ethics violation has occurred and that disciplinary actions are appropriate, it will forward its recommendations to ASCE's Executive Committee or Board of Direction for a formal hearing on the matter.
