  • 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.

  • "A Question of Ethics" Articles

    In October 2020, the Board of Direction adopted its first comprehensive rewrite of the ASCE Code of Ethics in more than 45 years. The previous column, which appeared in the December 2020 issue, outlined significant structural changes to the code - most notably, its organization of ethical duties into a hierarchy of five "stakeholders"- and reviewed the similarities and differences between the new code and its predecessor with respect to the engineer's first and highest stakeholder: Society. This second of two columns on the new code continues this comparison by reviewing the duties owed to the remaining four stakeholders.

    On Oct. 26, 2020, the ASCE Board of Direction approved a comprehensive rewrite of the ASCE Code of Ethics, the most extensive change to the Society's ethical code in more than 45 years. This is the first of two columns that will review the new code and highlight noteworthy areas of difference from, and consistency with, the code it replaces.

    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.
