Topic: Safety of construction materials.

Engineering disciplines: Mechanical, Materials.

Ethical issues: Safety, Communication, Whistleblowing, Power.

Educational level: Beginner.

Educational aim: To develop ethical awareness. Ethical awareness is when an individual determines that a single situation has moral implications and can be considered from an ethical point of view.

 

Learning and teaching notes:

This case concerns a construction engineer navigating multiple demands. The engineer must evaluate trade-offs between technical specifications, historical preservation, financial limitations, social needs, and safety. Some of these issues have obvious ethical dimensions, while others are ethically more ambiguous. In addition, the engineer must navigate a professional scenario in which different stakeholders try to influence the resolution of the dilemma.

This case study addresses two of AHEP 4’s themes: The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills). To map this case study to the AHEP outcomes specific to a programme under these themes, access AHEP 4 here and navigate to pages 30-31 and 35-37.

The dilemma in this case is presented in two parts. If desired, a teacher can use Part one in isolation, but Part two develops and complicates the concepts presented in Part one to provide for additional learning. The case allows teachers the option to stop at multiple points for questions and / or activities as desired.

Summary:

Krystyna is a construction engineer working as part of a team that is retrofitting a Victorian-era factory into multi-unit housing. As an amateur history buff, she is excited to be working on a listed building for the first time in her career after finishing university three years ago. However, this poses additional challenges: she must write the specification for glass windows that will maintain the building’s heritage status but also conform to 21st century safety standards and requirements for energy efficiency. In addition, Krystyna feels under pressure because Sir Robert, the developer of the property, is keen to maximise profits while maintaining the historic feel valued by potential buyers. He also wants to get the property on the housing market as soon as possible to help mitigate a housing shortage in the area. This is the first of many properties that Dave, the project’s contractor who is well-regarded locally and has 30 years of experience working in the community, will be building for Sir Robert. This is the first time that Krystyna has worked with Dave.

 

Optional STOP for questions and activities:

1. Discussion: What competing values or motivations might conflict in this scenario?

2. Discussion: What codes, standards and authority bodies might be relevant to this scenario?

3. Activity: Assemble a bibliography of relevant professional codes, standards, and authorities.

4. Activity: Undertake a technical project relating to testing glass for fire safety and / or energy efficiency.

5. Activity: Research the use of glass as a building material throughout history and / or engineering innovations in glass production.

 

Dilemma – Part one:

On her first walk through the property with Dave, Krystyna discovers that the factory building has large floor-to-ceiling windows on the upper stories. Dave tells her that these windows were replaced at some point in the past 50 years before the building was listed, at a time when it wasn’t used or occupied, although the records are vague. The glass is in excellent condition and Sir Robert has not budgeted either the time or the expense to replace glass in the heritage building.

While writing the specification, Krystyna discovers that the standards for fire protection as well as impact safety and environmental control have changed since the glass was most likely installed. After this research, she emails Dave and outlines what she considers to be the safest and most responsible form of mitigation: to fully replace all the large windows with glass produced by a supplier with experience in fire-rated safety glass for heritage buildings. To justify this cost, she highlights the potential dangers to human health and the environment of not replacing the glass.

Dave replies with a reassuring tone and refers to his extensive experience as a contractor. He feels that too many additional costs would be incurred such as finding qualified installers, writing up new architectural plans, or stopping work altogether due to planning permissions related to historic properties. He argues that there is a low probability of a problem actually arising with the glass. Dave encourages Krystyna not to reveal these findings to Sir Robert so that “future conflicts can be avoided.”

 

Optional STOP for questions and activities:

1. Discussion: What ethical issues that can be identified in this scenario?

2. Discussion: What interpersonal dynamics might affect the way this situation can be resolved?

3. Discussion: If you were the engineer, what action would you take, if any?

4. Activity: Identify all potential stakeholders and their values, motivations, and responsibilities using the SERM found in the Learning and teaching resources section.

5. Activity: Role-play the engineer’s response to the contractor or conversation with the developer.

6. Discussion: How do the RAEng/Engineering Council Statement of Ethical Principles and the Society of Construction Law Statement of Ethical Principles inform what ethical issues may be present, and what solutions might be possible?

 

Dilemma – Part two:

After considerable back and forth with Dave, Krystyna sees that she is unlikely to persuade him to make the changes to the project that she has recommended. Now she must decide whether to go against his advice and notify Sir Robert that they have disagreed about the best solution. Additionally, Krystyna has begun to wonder whether she has a responsibility to future residents of the building who will be unaware of any potential dangers related to the windows. Meanwhile, time is moving on and there are other deadlines related to the project that she must turn her focus to and complete.

 

Optional STOP for questions and activities:

The Society of Construction Law’s Statement of Ethical Principles advises “provid[ing] information and warning of matters . . . which are of potential detriment to others who may be adversely affected by them.”

1. Activity: Debate whether or not Krystyna has an ethical or professional responsibility to warn relevant parties.

2. Discussion: If Krystyna simply warns them, is her ethical responsibility fulfilled?

3. Activity: Map the value conflicts and trade-offs Krystyna is dealing with. Use the Mapping Actors and Processes article in the Learning and teaching resources section.

4. Discussion: If you were Krystyna, what would you do and why?

5. Discussion: In what ways are the professional codes helpful (or not) in resolving this dilemma?

6. Discussion: ’Advises’ or ‘requires’? What’s the difference between these two words in their use within a code of ethics? Could an engineer’s response to a situation based on these codes of ethics be different depending on which of these words is used?

Ethical issues: Respect for the environment; Social responsibility; Risk.

Professional situations: Public health and safety, Communication.

Educational level: Beginner.

Educational aim: To develop ethical awareness. Ethical awareness is when an individual determines that a single situation has moral implications and can be considered from an ethical point of view.

 

Learning and teaching notes:

This case involves a dilemma that most engineering students will have to face at least once in their careers: which job offer to accept. This study allows students to consider how personal values affect professional decisions. The ethical aspect of this dilemma comes from weighing competing moral goods –that is, evaluating what might be the better choice between two ethically acceptable options. In addition, the case offers students an introduction to ethical principles underpinning EU environmental law, and a chance to debate ethical aspects surrounding emerging technologies. Finally, the case invites consideration of the injustices inherent in proposed solutions to climate change.

This case study addresses two AHEP 4 themes: The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills). To map this case study to AHEP outcomes specific to a programme under these themes, access AHEP 4 here and navigate to pages 30-31 and 35-37.

Summary:

Olivia is a first-generation university student who grew up on a farm in rural Wales and was often frustrated by living in such a remote environment. When she received excellent A levels in maths and sciences, she took a place on a chemical engineering course in London.

Olivia became passionate about sustainability and thrived during her placements with companies that were working on innovative climate solutions. One of the most formative events for her  was COP26 in Glasgow. Here, she attended debates and negotiations that contributed to new global agreements limiting global warming to 1.5°C. Following this experience, Olivia has been looking for jobs that would allow her to work on the front line combating climate change.

 

Dilemma – Part one:

Olivia has received two job offers. One is a very well-paid position at CarGro, a small firm not far from her family farm. This company works on chemical analysis for soil carbon storage – the ability of soil’s organic matter to sequester carbon-rich compounds and therefore offset atmospheric CO2. 

The other offer is for an entry-level position at EnSol, a company developing the feasibility of stratospheric aerosol injection. This technology aims to mimic the effect that volcanic eruptions have on the atmosphere when they eject particles into the stratosphere that reflect sunlight and subsequently cool the planet. EnSol is a start-up located in Bristol that has connections with other European companies working on complementary technologies.

While considering these two offers, Olivia recalls an ethics lesson she had in an engineering design class. This lesson examined the ethical implications of projects that engineers choose to work on. The example used was of a biomedical engineer who had to decide whether to work on cancer cures or cancer prevention, and which was more ethically impactful. Olivia knows that both CarGro and EnSol have the potential to mitigate climate change, but she wonders if one might be better than the other. In addition, she has her own goals and motivations to consider: does she really want to work near her parents again, no matter how well-paid that job is?

 

Optional STOP for questions and activities: 

1. Discussion: Personal values – what personal values will Olivia have to weigh in order to decide which job offer to accept? 

2. Activity: research the climate mitigation potential of soil carbon sequestration (SCS) and stratospheric aerosol injection (SAI).

3. Discussion: Professional values – based on the research, which company is doing the work that Olivia might feel is most ethically impactful? Make an argument for both companies.

4. Discussion: Wider impact – what impact does the work of these two companies have? Consider this on local, regional, and global scales. Who benefits from their work, and who does not?

5. Discussion: Technical integration – undertake a technical activity in the areas of chemical engineering, energy and / or environmental engineering related to the climate mitigation potential of SCS and SAI.

 

Dilemma – Part two:

To help her with the decision, Olivia talks with three of her former professors. The first is Professor Carrera, whom Olivia accompanied to COP26. Professor Carrera specialises in technology policy, and tells Olivia about the precautionary principle, a core component of EU environmental law. This principle is designed to help governments make decisions when outcomes are uncertain.

The second is Professor Adams, Olivia’s favourite chemical engineering professor, who got her excited about emerging technologies in the area of climate change mitigation. Professor Adams emphasises the opportunity at EnSol provides, to be working on cutting-edge research and development – “the sort of technology that might make you rich, as well!”

Finally, Olivia speaks to Professor Liu, an expert in engineering ethics. Professor Liu’s latest book on social responsibility in engineering argues that many climate change mitigation technologies are inequitable because they unfairly benefit rich countries and have the potential to be risky and burdensome to poorer ones.

Based on these conversations, Olivia decides to ask the hiring managers at CarGro and EnSol some follow-up questions. Knowing she was about to make these phone calls, both her mother and her best friend Owen (who has already secured a job in Bristol) have messaged her with contradictory advice.  What does Olivia ask on the calls to CarGro and EnSol to help her make a decision? Ultimately, which job should Olivia take?

 

Optional STOP for questions and activities:

1. Activity and discussion: research the precautionary principle – what have been the potentially positive and negative aspects of its effect on EU policy decisions related to the environment?

2. Activity: identify the risks and benefits of SCS and SAI for different communities.

3. Activity: map the arguments of the three professors. Whose perspective might be the most persuasive to Olivia and why?

4. Activity: rehearse and role play phone calls with both companies.

5. Activity: debate which position Olivia should take.

Topic: Smart meters for responsible everyday energy use.

Engineering disciplines: Electrical engineering

Ethical issues: Integrity, Transparency, Social responsibility, Respect for the environment, Respect for the law

Professional situations: Communication, Privacy, Sustainability

Educational level: Beginner

Educational aim: To encourage ethical motivation. Ethical motivation occurs when a person is moved by a moral judgement, or when a moral judgement is a spur to a course of action. 

 

Learning and teaching notes:

This case is an example of ‘everyday ethics’. A professional engineer must give advice to a friend about whether or not they should install a smart meter. It addresses issues of ethical and environmental responsibility as well as public policy, financial burdens and data privacy. The case helps to uncover values that underlie assumptions that people hold about the environment and its connection to human life and services. It also highlights the way that those values inform everyday decision-making.

This case study addresses two of AHEP 4’s themes: The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills). To map this case study to AHEP outcomes specific to a programme under these themes, access AHEP 4 here and navigate to pages 30-31 and 35-37.

The dilemma in this case is presented in three parts that build in complexity. If desired, a teacher can use Part one in isolation, but Part two and Part three develops and complicates the concepts presented in Part one in order to provide additional learning. The case allows teachers the opportunity to stop at various points to pose questions and/or set activities.

Summary – Part one:

Sam and Alex have been friends since childhood. As they have grown older, they have discovered that they hold very different political and social beliefs, but they never let these differences of opinion get in the way of a long and important friendship. In fact, they often test their own ideas against each other in bantering sessions, knowing that they are built on a foundation of respect.

Sam works as an accountant and Alex has become an environmental engineer. Perhaps naturally, Alex often asks Sam for financial advice, while Sam depends on Alex for expert information related to sustainability and the environment. One day, knowing that Alex is knowledgeable about the renewable energy industry and very conscious of the impact of energy use at home, Sam messages Alex to say he is getting pressure from his energy company to install a smart meter.

Sam has been told that smart metering is free, brings immediate benefits to customers by helping them to take control of their energy usage, and is a key enabler for the transition away from fossil fuels use and towards the delivery of net zero emissions by 2050. Smart meters give consumers near real-time information on energy use, and the associated cost, enabling them to better manage their energy use, save money and reduce emissions. A further benefit is that they could charge their electric car far more cheaply using a smart meter on an overnight tariff.

Yet Sam has also read that smart meters ‘go dumb’ if customers switch providers and, as a pre-payment customer, this option may not be available with a smart meter. In addition, Sam suspects that despite claims that the smart meter roll out is free, the charge is simply being passed on to customers through their energy bills instead. Alex tries to give Sam as much good information as possible, but the conversation ends with the decision unresolved.

 

Optional STOP for questions and activities: 

1. Discussion and activity: Personal values – We know that Sam and Alex have different ideas and opinions about many things. This probably stems from a difference in how they prioritise values. For instance, valuing transparency over efficiency, or sustainability over convenience. Using this values activity as a prompt, what personal values might be competing in this particular case?

2. Discussion and activity: Everyday ethics – Consider what values are involved in your everyday choices, decisions, and actions. Write a reflective essay on three events in the past week that, upon further analysis, have ethical components.

3. Discussion: Professional values – Does Alex, as an environmental engineer, have a responsibility to advocate installing smart meters? If so, does he have more responsibility than a non-engineer to advocate for this action? Why, or why not?

4. Discussion: Wider impact – Are there broader ethical issues at stake here?

5. Activity: Role-play a conversation between Sam and Alex that includes what advice should be given and what the response might be.

 

Dilemma – Part two:

After getting more technical information from Alex, Sam realises that, with a smart meter, data on the household’s energy usage would be collected every 30 minutes.  This is something they had not anticipated, and they ask a number of questions about the implications of this. Furthermore, while Sam has already compared tariffs and costs as the main way to choose the energy provider, Alex points out that different providers use different energy sources such as wind, gas, nuclear, coal, and solar. Sam is on a tight budget but Alex explains that the cheaper solution is not necessarily the most environmentally responsible choice. Sam is frustrated: now there is something else to consider besides whether or not to install the smart meter.

 

Optional STOP for questions and activities:  

1. Activity: Technical integration – Undertake an electrical engineering technical activity related to smart meters and the data that they collect.

2. Activity: Research what happens with the data collected by a smart meter. Who can access this data and how is privacy protected? How does this data inform progress towards the energy transition from fossil fuels?

3. Activity: Research different energy companies and their approach to responsible energy sourcing and use. How do these companies communicate that approach to the public? Which company would you recommend to your friend and why?

4. Activity: Cost-benefit analysis – Sometimes the ethical choice is the more expensive choice. How do you balance short- and long-term benefits in this case? When, if ever, would it be ethically right to choose energy from non-renewable sources? How would this choice differ if the context being considered was different? For example, students could think about responsible energy use in industrialised economies versus the developing world and energy justice.

 

Dilemma – Part three:

Following this exchange with Sam, Alex becomes aware that one of the main obstacles in energy transition concerns communication with the public. Ideally, Alex wants to persuade family and other friends to make more responsible choices; however, it is clear that there are many more factors involved than can be seen in one glance. This includes what kinds of pressure is put on consumers by companies and the government. Alex begins to reflect on how policy drives what engineers think and do, and joins a new government network on Engineering in Policy.  

Alex and Sam meet up a little while later, and Sam announces that yes, a smart meter has been installed. At first Alex is relieved, but then Sam lets it slip that they are planning to grow marijuana in their London home. Sam asks whether this spike in energy use will be picked up as abnormal by a smart meter and whether this would lead to them being found out.

 

Optional STOP for questions and activities:  

1. Discussion: Personal values – What are the ethics involved in trying to persuade others to make similar choices to you?

2. Discussion and activity: Legal responsibility – What should Alex say or do about Sam’s disclosure? Role-play a conversation between Sam and Alex.

3. Discussion: Professional responsibility – What role should engineers play in setting and developing public policy on energy?

4. Activity: Energy footprint – Research which industries use the most energy and, on a smaller scale, which home appliances use the most energy.
