Statement of the Case: A small town hired Engineer A, a consulting mechanical engineer, to
design a water system that would replace their small public-utility system, fed from several wells
with water of doubtful quality. Engineer A proposed to pump water from a nearby river that had an adequate flow all year, but was subject to intermittent ice jams that, on the average, stopped
the flow for about 6 to 12 hours, once each winter. She proposed to overcome this stoppage by
constructing a small reservoir, which pumps would keep filled.
This reservoir had a volume equal to 48 hours’ consumption. The electric power lines serving the area were subject to icing and power failures, which occurred, on the average, for about 12 hours, once per year. Engineer A proposed to maintain power by installing a standby diesel generator in the pump-house so that when line power was lost, the generator would power the pumps. She presented the concept to the municipal Council, and the daily newspaper reported the story.
On reading the newspaper story, Engineer B, a chemical engineer with no water supply
experience, concluded that Engineer A was putting the taxpayers (including him) to unnecessary
expense by installing the standby pumps. Engineer B reasoned that the 48 hours’ supply in the
reservoir would be more than adequate to take care of both the ice-dams in the river and the
power supply failure, even if both occurred simultaneously.
Without getting in contact with Engineer A, he immediately wrote a stinging letter to the municipal Council, with a copy to the newspaper, identifying himself as a Professional Engineer and criticizing what he called “unnecessary and expensive duplication.” The letter closed with a flippant comment questioning either Engineer A’s honesty or competence. The municipal Council discussed the letter and, since a qualified engineer wrote it, the Council concluded that it would be politically unwise to
ignore it. The Council voted to ask Engineer A to respond in writing to Engineer B’s allegations.
Engineer A was surprised at this request from the Council, but felt obliged to honour it. She
dropped all other tasks and summarized her calculations in a report, which she had printed and
bound. She then returned to the municipal Council the following week and explained her
reliability calculations, which confirmed the configuration that she was recommending.
She explained that, while the newspaper story quoted average values, her calculations required
“worst-case” probabilities. Moreover, the local hospital depended on the water supply and
required higher reliability. In addition, it was indeed statistically probable that the ice-jams and
power failures would occur simultaneously. Other pumping or piping components might also fail
and prolong a water shortage, or the ice cover on the reservoir might limit the flow available.
Moreover, the proposal included a contingency for town expansion during the next 40 years. It
soon became clear that Engineer A’s proposal was a very reasonable solution to the problem.
Engineer A calculated her additional time and report preparation costs at about $5,000. While
she expected her design to undergo public scrutiny, she did not expect an uninformed attack from
a fellow engineer. She knew that the Code of Ethics required public opinions to be founded upon
“adequate knowledge and honest conviction,” so she called the provincial Association to ask
whether such thoughtless public criticism from Engineer B was unprofessional conduct.
Question: Was the opinion in Engineer B’s letter founded upon “adequate knowledge and
honest conviction,” as required by almost every Code of Ethics? Is Engineer B guilty of
unprofessional conduct?
Outcome: Engineer A decided that she had not suffered any loss of reputation, that she was too
busy to make a formal complaint, and declined to pursue the matter further. The Association
closed the file.
Authors’ Comments: Any citizen has the right to question public expenditures, including the
water proposal put forward by Engineer A. However, Engineer B was not merely a citizen asking
for more information. By identifying himself in his letter as a Professional Engineer, Engineer B
implied that he was competent in the area of expertise, aware of the details, and condemning
Engineer A’s design for engineering reasons. Engineer B was, therefore, expressing a public
opinion in an area outside his expertise, and he clearly violated the Code of Ethics.
More important, Engineer B’s implication of dishonesty or incompetence displayed a lack of courtesy
and good faith to a colleague, bordering on slander. This is also contrary to the Code of Ethics,
which requires us to treat colleagues with honesty and good faith. Engineer B’s actions were
therefore unprofessional. If Engineer A had pursued her complaint, Engineer B would likely
have received a reprimand. Although we must guard against wasteful public expenditures,
professional criticism must follow the Code of Ethics.
[NOTE: This case study is similar to Case Study F-25: Meddling or Extending Public
Knowledge? but the professional’s actions are significantly different, resulting in a different
outcome.]
