14. An engineer is retained to preform an inspection of asphalt on a bridge. During the
inspection, the engineer notices a potential defect in structural wall that may have
contributed to a fatal accident that occurred on the bridge in the past year. The engineer
notes that this information in his field notes and then notifies his client of the potential
defect. The client then notifies the public agency that owns the bridge. At the request of
the public agency, the engineer does not include the information about the wall in his
final report on the asphalt inspection, but the engineer does retain the information in his
field notes.
Which of the following statements best captures the ethical considerations presented?
a. The engineer acted ethically as the potential defect was raised to the appropriate
parties for further consideration but was not included in the report since it was
speculation and not based on actual design calculations, testing our evaluation by
a competent professional.
b. The engineer acted ethically to notify the agencies, but acted unethically in not
including the potential wall defect in the final report as this information should be
documented to ensure further evaluation is performed.
c. The engineer acted unethically by not preforming further analysis of the potential
defect to determine the adequacy of the bridge.
d. The engineer acted unethically, since ignoring the potential defect and leaving it
out of the final report could jeopardize the health, safety, or welfare of the public
and the engineer has an obligation to document the potential defect to appropriate
legal authorities.

15. An engineer is retained to preform a routine mine inspection. Upon arriving at the site,
the engineer realized he forgot his safety boots and will be unable to enter the mine to
preform the inspection. Due to the remote nature of the site, the mine company routinely
provides visitors to the site with required personal protective equipment including boots
for use at the site. The engineer recognizes that accepting the boots will violate his
company’s code of ethics since the company prohibits accepting gifts that have value of
more than $100:
Select all of the following approaches that would be considered ethical:
a. The engineer may accept the boots and is not obligated to notify his employer as
the boots are nominally more than $100. By accepting the boots, the engineer will
avoid costs associated with delaying the inspection, resulting in a net savings to
the company.
b. The engineer may accept the boots and is obligated to notify his employer since
the boots are more than $100 threshold set by the employer.
c. The engineer may use the boots and return them after the inspection. The engineer
is not obligated to notify his employer since the boots were used and returned.
d. The engineer may decline the boots and request that the inspection be postponed.
e. The engineer is not obligated to disclose his forgetting his boots and should
postpone the inspection without the need for further explanation.
f. The engineer should proceed with the inspection and forego the safety boot
requirement since a personal impact and does not affect the safety of others.

the drawings.
An ethical response for Engineer A would be:
a. To ignore the request as he has no obligation to the former employer.
b. To refuse to sign and seal the drawings as he no longer works at Firm X and is no
longer in direct control of the design.

drawings.

liability concerns.
