Engineering Ethics Lesson
Introduction
Throughout documented time, engineers have struggled with the value provided through innovation versus the negative impact of that innovation. The products and systems of engineering have a substantial human impact when the product is flawed or the design in inadequate or unsafe. The Hippocratic Oath for physicians evolved since initialized before 300BC. Just as medical practitioners are required to do no harm in the course of their work, engineers also have a unique responsibility to ensure the result of their endeavors are useful and not harmful. Prior to the mid-19th Century engineers bore this professional responsibility through personal conviction alone.
The awareness of the unique professional responsibilities of engineers rose to prominence during the 19th Century and beginnings of 20th Century when the value of engineers and technological innovation became more significant to societies. The Industrial Revolution drove significant industrial development. Manufacturing and civil infrastructure was increasing throughout developed communities and nations. These major changes drove the need for more engineering talent. As a result, professional engineering organizations emerged to improve professionalism and skills within each field.
The rise of rapid development for bridges and railroads also saw a large number of structural failures. Unfortunately, too many of these bridges collapsed resulting in loss of life. These catastrophes most often occurred during extreme conditions when the structure was under considerable load.
These engineering failures led to the development of professional engineering societies to establish standards for ethical and professional behavior.

Engineering Failures
The topic of ethics in engineering could be discussed in any era where engineering was a field of importance and the products of engineers affected communities and societies. However, we have limited knowledge of failures in times prior to industrialization.
This is a list of notable engineering failures in history. Each of these were generally assessed as structure failures due to loading conditions.
- the Fidenae Amphitheater collapse in Italy (27AD) killing tens of thousands
- the ancient Circus Maximus Roman chariot racing stadium (built in segments from 329BC until collapse 140AD)
- the Stirling Bridge collapse in Scotland (1297)
The following examples are from recent history. Please review each to understand what went wrong, why it failed, and the response to the failure.

Read each statement and decide whether it is TRUE or FALSE?
The engineering field does not have the responsibility for the safety of the products or processes created. |
The period of the Industrial Revolution experienced many bridge failures. |
The awareness of the unique professional responsibilities of engineers rose to prominence during the 16th Century when the value of engineers and technological innovation became more significant to societies. |
Professional engineering organizations were established to ensure quality of product and demonstration of ethical behavior in the engineering profession. |
Failures in large engineered structures were not a big deal in the historic time because not many people were killed. |
The Ashtabula River railroad bridge was made of steel and wood. |
The Ashtabula River railroad bridge failed because the project engineer specified the wrong material. |
The St. Francis Dam collapsed due to an earthquake. |
The American Society of Mechanical Engineers (ASME) focuses on quality and standardization of mechanical components. |
The American Society of Civil Engineers (ASCE) established a code of ethics focused on safety, health and welfare of the public. |

Why do you think engineers study the failures of engineered projects?
Engineers are naturally curious and natural learners. Engineers will investigate and learn from the mistakes of others to ensure mistakes are not repeated.
