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.
"ZERO TOLERANCE" means more than simply a passive resistance to corruption but instead signifies an active commitment to combat corruption wherever it occurs.
