Engineers shall hold paramount the safety, health and welfare of the public and shall strive to
comply with the principles of sustainable development in the performance of their professional
duties.
a. Engineers shall recognize that the lives, safety, health and welfare of the general public are
dependent upon engineering judgments, decisions and practices incorporated into

them, which are determined to be safe for public health and welfare in conformity with
accepted engineering standards.
c. Engineers whose professional judgment is overruled under circumstances where the safety,
health and welfare of the public are endangered, or the principles of sustainable
development ignored, shall inform their clients or employers of the possible consequences.
d. Engineers who have knowledge or reason to believe that another person or firm may be in
violation of any of the provisions of Canon 1 shall present such information to the proper

of sustainable development so as to enhance the quality of life of the general public.
Canon 2.
Engineers shall perform services only in areas of their competence.
a. Engineers shall undertake to perform engineering assignments only when qualified by
education or experience in the technical field of engineering involved.
b. Engineers may accept an assignment requiring education or experience outside of their own
fields of competence, provided their services are restricted to those phases of the project in
which they are qualified. All other phases of such project shall be performed by qualified
associates, consultants, or employees.

dealing with subject matter in which they lack competence by virtue of education or
experience or to any such plan or document not reviewed or prepared under their
supervisory control.

They shall include all relevant and pertinent information in such reports, statements, or
testimony.
c. Engineers, when serving as expert witnesses, shall express an engineering opinion only
when it is founded upon adequate knowledge of the facts, upon a background of technical

d. Engineers shall issue no statements, criticisms, or arguments on engineering matters which
are inspired or paid for by interested parties, unless they indicate on whose behalf the
statements are made.

department shall not participate in considerations or actions with respect to services
solicited or provided by them or their organization in private or public engineering practice.
e. Engineers shall advise their employers or clients when, as a result of their studies, they

accomplishments.
f. Engineers may advertise professional services in a way that does not contain misleading
language or is in any other manner derogatory to the dignity of the profession. Examples of

participation in projects described.
A statement of the engineers' names or the name of the firm and statement of the
type of service posted on projects for which they render services.

which are factual and dignified. Such articles shall not imply anything more than
direct participation in the project described.

The Society’s Code of Ethics was adopted on September 2, 1914 and was most recently amended on July 23, 2006. Pursuant to the
Society’s Bylaws, it is the duty of every Society member to report promptly to the Committee on Professional Conduct any observed
violation of the Code of Ethics.

In April 1975, the ASCE Board of Direction adopted the fundamental principles of the Code of Ethics of Engineers as accepted by the
Accreditation Board for Engineering and Technology, Inc. (ABET).

In October 2009, the ASCE Board of Direction adopted the following definition of Sustainable Development: “Sustainable Development
is the process of applying natural, human, and economic resources to enhance the safety, welfare, and quality of life for all of the society
while maintaining the availability of the remaining natural resources.”
