The recent apartment building collapse in Miami, Florida, is a tragic reminder of the huge impacts engineering can have on our lives. Disasters such as this force engineers to reflect on their practice and perhaps fundamentally change their approach. Specifically, we should give much greater weight to ethics when training engineers.
Engineers work in a vast range of fields that pose ethical concerns. These include artificial intelligence, data privacy, building construction, public health, and activity on shared environments (including Indigenous communities). The decisions engineers make, if not fully thought through, can have unintended consequences – including building failures and climate change.
Engineers have ethical obligations (such as Engineers Australia’s code of ethics) that they must follow. However, as identified at UNSW, the complexity of emerging social concerns creates a need for engineers’ education to equip them with much deeper ethical skill sets.
Engineering is seen as a trusted and ethical profession. In a 2019 Gallup poll, 66% rated the honesty and ethical standards of engineers as high/very high, on a par with medical doctors (65%).
However, ethics as a body of knowledge is massive. There are nearly as many academic papers on ethics as mathematics, and clearly more than on artificial intelligence.
With such a rich backdrop of knowledge, engineers must embrace ethics in a way that previous generations embraced mathematics. Complex societal problems make much greater demands on engineering thinking than in the past. We need to consider whole and complex systems, not just issues as individual challenges.
The construction industry provides a topical example of such complexity. Opal Tower in Sydney, Lacrosse building in Melbourne, Grenfell Tower in London and Torch Tower in Dubai became household names for all the wrong reasons.
Importantly, these issues of poor quality and performance don’t arise from new technology or know-how. They involve well-established technical domains of engineering: combustible cladding, fire safety, structural adequacy and so on. A fragmented design and delivery process with unclear responsibility and/or accountability has led to poor outcomes.
These issues prompted the Australian Building Ministers’ Forum to commission the Shergold Weir Report, followed by a task force to implement its recommendations across Australia.
There are real shortcomings in the legal and contractual processes for allocating and “commoditising” risk in the industry. However, ethics should do the heavy lifting when legal frameworks are lacking. One key question is whether erosion of professional ethics has played a part in this state of affairs. The answer is a likely “yes”.
Engineers face ethical dilemmas such as:
Or worse: “Do I resort to phoenixing to avoid any accountability?”
The enduring connection of Aboriginal Australians to Country requires engineers to navigate ethical considerations in Indigenous communities. Engineers must reconcile the legal, technical and regulatory requirements of their projects with Indigenous cultural values and needs. They might not be properly equipped to navigate ethical scenarios when they encounter unfamiliar cultural connections, or regulations are insufficient.
Consider, for example, the sacred sites of the McArthur River Mine. Traditional owners have raised concerns that current mining activities do not adequately protect sacred and cultural heritage sites. Evidence given by community leaders provides insight into the intimate and diverse relationship that traditional owners have with the land.
In considering such evidence, engineers must be able to evaluate both physical site risks (such as acidification of mine tailings and contamination of water bodies) and cultural risks (such as failing to identify all locations of cultural value).
How might we tackle such complicated projects? By properly engaging with traditional communities and by having diverse teams with multiple worldviews and experiences, along with strong technical skills. The broad field of ethical knowledge provides the skill sets to attempt to reconcile the diverse considerations.
Engineering students’ ethical development requires a holistic approach. One assessment suggested:
“[…] that institutions integrate ethics instruction throughout the formal curriculum, support use of varied approaches that foster high‐quality experiences, and leverage both influences of co‐curricular experiences and students’ desires to engage in positive ethical behaviours.”
The curriculum should include:
Ethics is not an “add-on” subject. It must permeate all aspects of tertiary education – teaching, research and professional behaviour.
While the arguments for acting now are strong, market realities will also drive the process. The upcoming generation will likely displace those who are slow or reluctant to adapt.
For instance, engineering firms are under pressure from their own staff on the issue of climate change. More than 1,900 Australian engineers and nearly 180 engineering organisations have signed a declaration committing them to evaluate all new projects against the need to mitigate climate change.
Future engineers must transcend any remaining single-solution mindsets from the past. They’ll need to embrace a much more complex and socially minded ethics. And that begins with their university education.
