Learning and teaching notes:  

This case study involves a young engineering student on an industrial placement year at a firm that manufactures cosmetics. The student has been working hard to impress the company as they are aware that this may lead to them being offered a job upon graduation. They are involved in a big project that focuses on alternative, more environmentally friendly cosmetic chemistries. When they notice a potential problem with the new formulation, they must balance their commitment towards environmental sustainability with their desire to work for the company upon graduation.  

This dilemma can be addressed from a micro-ethics point of view by analysing personal ethics, intrinsic motivations and moral values. It can also be analysed from a macro-ethics point of view, by considering corporate responsibility and intergenerational justice. The dilemma can also be framed to emphasise global responsibility and environmental justice whereby the engineers consider the implications of their decisions on global communities and future generations.  

This case study addresses two of the themes from the Accreditation of Higher Programmes fourth edition (AHEP4): 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 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.

Dilemma – Part one: 

Microplastics are solid plastic particles composed of mixtures of polymers and functional additives; they also contain residual impurities. Microplastics generally fall into two groups: those that are unintentionally formed as a result of the wear and tear of larger pieces of plastic, and those that are deliberately manufactured and added to products for specific purposes (primary microplastics). Microplastics are intentionally added to a range of products including cosmetics, in which they act as abrasives and can control the thickness, appearance, and stability of a product.  

Legislation pertaining to the use of microplastics varies worldwide and several loopholes in the regulations have been identified. Whilst many multinational companies have fought the introduction of such regulations, other stakeholders have urged for the use of the precautionary principle, suggesting that all synthetic polymers should be regulated in order to prevent significant damage to both the environment and human health. 

Recently, several changes to the regulation of microplastics have been proposed within Europe. One that affects the cosmetics industry particularly concerns the intentional addition of microplastics to cosmetics. Manufacturers, especially those who export their products, have therefore been working to change their products. 

 

Optional STOP for questions and activities:  

1. Discussion: Professional values – What ethical principles and codes of conduct are applicable to the use of microplastics? Should these change or be applied differently when the microplastics are used in products that may be swallowed or absorbed through the eyes or skin?

2. Activity: Research some of the current legislation in place surrounding the use of microplastics. Focus on the strengths and limitations of such legislation.  

3. Activity: Technical integration – Research the potential health and environmental concerns surrounding microplastics. Investigate alternative materials and/or technological solutions to the microplastic ‘problem’.  

4. Discussion: Familiarise yourself with the precautionary principle. What are the advantages and disadvantages of applying the precautionary principle in this situation?  

 

Dilemma – Part two: 

Alex is a young engineering student on an industrial placement year at a firm that manufactures cosmetics. The company has been commended for their sustainable approach and Alex is really excited to have been offered a role that involves work aligned with their passion. They are working hard to impress the company as they are aware that this may lead to them being offered a job upon graduation.  

Alex is involved in a big project that focuses on alternative, more environmentally friendly cosmetic chemistries. Whilst working in the formulation laboratory, they notice that some of the old filler material has been left near the preparation area. The container is not securely fastened, and residue is visible in the surrounding area. The filler contains microplastics and has recently been taken out of products. However, it is still in stock so that it could be used for comparative testing, during which the performance of traditional, microplastic containing formulations are compared to newly developed formulations. It is unusual for the old filler material to be used outside of the testing laboratory and Alex becomes concerned about the possibility that the microplastics have been added to a batch of the new product that had been made the previous day. They raise the issue to their supervisor, asking whether the new batch should be quarantined.  

“We wouldn’t ever hold such a large, lucrative order based on an uncertainty like that,” the supervisor replies, claiming that even if there was contamination it wasn’t intentional and would therefore not be covered by the legislation. “Besides, most of our products go to countries where the rules are different.” 

Alex mentions the health and environmental issues associated with microplastics, and the reputation the company has with customers for being ethical and sustainable. They suggest that they bring the issue up with the waste and environmental team who have expertise in this area.  

Their supervisor replies: “Everyone knows that the real issue is the microplastics that are formed from disintegration of larger plastics. Bringing up this issue is only going to raise questions about your competence.”  

 

Optional STOP for questions and activities: 

1. Discussion: Personal values – What competing personal values or motivations might trigger an internal conflict for Alex? 

2. Activity: Research intergenerational justice and environmental justice. How do they relate to this case? 

3. Activity: Identify all potential stakeholders and their values, motivations, and responsibilities. 

4. Discussion: Consider both the legislation in place and the RAEng/Engineering Council Ethical Principles. What should Alex do according to each of these? Is the answer the same for both? If not, which set of guidance is more important? 

5. Discussion: How do you think the issue of microplastics should be controlled? 

6. Activity: Alex and their boss are focused on primary microplastics. Consider the lifecycle of bulk plastics and the various stakeholders involved. Who should be responsible for the microplastics generated during the disintegration of plastic products?

7. Discussion: What options for action does Alex have available to them? What are the advantages and disadvantages of each approach? What would you do if you were Alex? 

8. Activity: Technical integration related to calculations or experiments on microplastics.

Learning and teaching notes:

This case involves an engineer responsible for verifying the source of recycled construction material to ensure it is not contaminated. The case is presented in three parts. Part one focuses on the environmental, professional, and social contexts and may be used in isolation to allow students to explore both micro-ethical and macro-ethical concerns. Parts two and three bring in a dilemma about public information and communication and allows students to consider their positions and potential responses. The case allows teachers the option to stop at multiple points for questions and / or activities as desired.

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).

Dilemma – Part one:

Charlie is a junior environmental engineer who started working at Circle Mat after graduating. Circle Mat is a construction products company that takes pride in using recycled materials from waste in their products, such as mortars and concretes. In fact, Circle Mat was recently nominated by the National Sustainability Association in the prize for the most innovative and sustainable production chains.

Charlie’s role is to ensure that the quality standards of the recycled waste used in the products are met. She is sent a report every two weeks from the factories receiving the waste and she checks the properties of this waste. While she is also supposed to visit all the factories once a month, her direct supervisor, Sam, advised her to visit only those factories where data shows that there are problems with the quality. While it is Charlie’s responsibility to verify the quality and to create the factory visit plan, she trusts her line manager as to how best approach her work.

Among all the factories with which they are working, the factory in Barretton has always had the highest quality standards, and since it is very far from where Charlie is based, she has postponed for months her visit to that factory.

 

Optional STOP for questions and activities:

1. Discussion: Charlie is responsible for checking the quality from the data she receives, but what about the quality/reliability of the data? Where does her responsibility begin and end? What ethical guidance, codes, or frameworks can help her decide?

2. Activity: Research the issue of asbestos, including current science, potential risks, and legal implications.

3. Discussion: Macroethical context – What is circularity, and how does it relate to climate goals or environmental practice?

  

Dilemma: Part two:

After several months, she finally goes to the town where the factory is located. Before getting to the factory, she stops for a coffee at the town’s café. There, she enquires of the waiter about the impacts of the factory on the town. The waiter expresses his satisfaction and explains that since Circle Mat started operations there, the town has become much more prosperous.

When Charlie reaches the factory, she notices a pile of waste that, she assumes, is the one that is being used as recycled aggregate in concrete. Having a closer look, she sees that it is waste from demolition of a building, with some insulation walls, concrete slabs and old pipes. At that moment, the head of the factory arrives and kindly shows Charlie around.

At the end of the visit, Charlie asks about the pile, and the head says that it is indeed demolition waste from an old industrial building. By the description, Charlie remembers that there are some buildings in the region that still contain asbestos, so asks whether the demolition material could potentially have asbestos. To Charlie’s surprise, the head reacts aggressively and says that the visit is over.

 

Optional STOP for questions and activities:

1. Activity: Use an environmental and social Life Cycle Assessment tool to assess the environmental and social impacts that the decision that Charlie makes might have.

2. Discussion: Map possible courses of action regarding the approach that Charlie could adopt when the factory head tries to shut down the visit. Discuss which is the best approach and why. Some starting questions would be: What should Charlie do? What feels wrong about this situation?

3. Discussion: if she reports her suspicions to her manager, what data or evidence can she present? Should she say anything at all at this point?

 

Dilemma – Part three:

In the end, Charlie decides not to mention anything, and after writing her report she leaves Barretton. A few days later, Circle Mat is announced to be the winner of the prize by the National Sustainability Association. Circle Mat organises a celebration event to be carried out in Barretton. During the event, Charlie discovers that Circle Mat’s CEO is a relative of the mayor of Barretton.

She is not sure if there really is asbestos in the waste, and also she does not know if other factories might be behaving in the same way. Nonetheless, other junior engineers are responsible for the other factories, so she doesn’t have access to the information.

Some days after the event, she receives a call from a journalist who says that they have discovered that the company is using waste from buildings that contain asbestos. The journalist is preparing an article to uncover the secret and wants to interview her. They ensure that, if she wants, her identity will be kept anonymous. They also mention that, if she refuses to participate, they will collect information from other sources in the company.

 

Optional STOP for questions and activities:

1. Activity: Technical integration related to measuring contaminants in waste products used for construction materials.

2. Discussion: What ethical issues can be identified in this scenario? Check how ethical principles of the construction sector inform the ethical issues that may be present, and the solutions that might be possible.

3. Discussion: What interpersonal and workplace dynamics might affect the approach taken to resolve this situation? 

4. Discussion: Would you and could you take the interview with the journalist? Should Charlie? Why or why not?

5. Activity: In the case of deciding to take the interview, prepare the notes you would take to the interview.

Case enhancement: Industrial pollution from an ageing pipeline

Activity: Prompts to facilitate discussion activities.

Author: Sarah Jayne Hitt, Ph.D. SFHEA (NMITE, Edinburgh Napier University).

 

Overview:

There are several points in this case during which an educator can facilitate a class discussion about relevant issues. Below are prompts for discussion questions and activities that can be used. These correspond with the stopping points outlined in the case. Each prompt could take up as little or as much time as the educator wishes, depending on where they want the focus of the discussion to be.

 

Case Summary – Discussion prompts:

1. Professional Contexts. The question listed in the case study is meant to elicit students’ consideration of working as an engineer in a professional culture different from the one they are familiar with. To answer this question, educators could have students reflect quietly and make notes for a few minutes, or discuss with a partner before sharing with the class. If students are hesitant to engage in questions of cultural differences, they could be prompted to examine why they have that discomfort. Educators might also want to prepare for conversations like this by reviewing the guidance article Tackling tough topics in discussion.

2. Meeting Preparation. The question listed in the case study focuses on the choices that engineers make when presenting data; that is, should they show managers a complete or incomplete picture of the situation in question? What implications does that have in terms of managers’ ability to make decisions? The question also is meant to help students consider aspects of professional communication. Students could be tasked with actually doing a version of the meeting preparation as pairs in the classroom, or they could do this as a reflective exercise as well.

 

Dilemma – Part one – Discussion prompts:

1. Personal and Professional Responsibility. Here, students are being asked to explore their own personal responses to the informal housing situation outside the factory and interrogate whether or not that response could or should affect their professional actions. The question also investigates the scope of professional responsibility, and at what point an engineer has fulfilled this or fallen short. To engage students in this discussion, educators could split the class in half, with half the room discussing the position that Yasin does NOT have a responsibility, and why; and the other half discussing the position that Yasin DOES have a responsibility and why. Alternatively, students could be asked to write down their own answer to this question along with reasoning why or why not, and then the educator could ask volunteers to share responses in order to open up the discussion.

2. Economic Contexts. Students can use this question to expand on question 1 of this section, and in fact they may already have drawn cost into their reasoning. One way to open up this discussion is to think of the broader costs, meaning: is there a social or environmental cost that the company externalises through its polluting activities? Another way into the question is to go back to the question of responsibility, because engineers are routinely responsible for making budgets and judgements related to costs. Through this financial activity, are they able to advocate for more ethical practices, and should they?

 

Dilemma – Part two – Discussion prompts

1. Job Offer. This question is meant to point to the issue of bribery, and have students wrestle with the situations presented in the case. Educators could have students review various definitions of bribery, including the one in the RAEng’s Statement of Ethical Principles. They could compare this with the Engineering Council of India’s Code of Ethics. What do these two codes say about Yasin’s case? If they don’t give clear guidance, what should Yasin do? Students could discuss why or why not they think this is bribery in small or large groups, and could debate what Yasin’s action should be and why.

2. External Reporting. This question addresses whistleblowing, and what responsibilities engineers have for reporting unethical actions to professional or legal entities. Students could be asked individually to answer the question and give reasons why, based on the codes of ethics relevant to the case. They could also answer the question based on their own personal values. Then they could discuss their responses in small groups and interrogate whether or not the codes conflict with their values. Educators could at this point raise the question of whether or not there may be different cultural expectations in this area that Yasin might have to navigate, and if so, if this should make any difference to the action he should take. Students could also be asked to chart out the personal and professional repercussions Yasin could experience for either action. This discussion could be good preparation for activity #5, the debate.

Case enhancement: Glass safety in a heritage building conversion

Activity: Do engineers have a responsibility to warn the public if there is a chance of risk?

Author: Cortney Holles (Colorado School of Mines, USA).

 

Overview:

This enhancement is for an activity found in the Dilemma Part two, Point 1 section of this case: Debate whether or not Krystyna has an ethical or professional responsibility to warn relevant parties (“of matters . . .  which are of potential detriment to others who may be adversely affected by them” – The Society of Construction Law’s Statement of Ethical Principles).

After introducing or studying the Glass Safety case, teachers may want students to dig deeper into the ethical issues in the case through a debate.  The resources and lesson plan below guide teachers through this lesson.

 

1. Introduce the debate assignment:

Students will debate whether or not Krystyna has an ethical or professional responsibility to warn relevant parties. Build in some time for students to prepare their arguments in small groups (either during class or as a homework assignment).  Create small groups of 2-5 students that can develop positions on each of the following positions on the question of the debate:

Does Krystyna have a responsibility to warn Sir Robert or future residents of the buildings about the glass?

 

2. Supporting the arguments in the debate with texts:

Provide students with resources that offer support for the different positions in the debate, listed below.  Perhaps you have assigned readings in the class they can be asked to reference for support in the debate.  Teachers could also assign students to conduct independent research on these stakeholders and positions if that matches the goals of the class.

 

Resources:

Journal articles:

Law:

Professional organisations:

Educational institution:

Ethics:

 

3. Running the debate in class:

Ethical issues: Environment, Health, Public good.

Professional situations: Bribery, Whistleblowing, Corporate social responsibility, Cultural competency.

Educational level: Advanced.

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 requires an engineer to balance multiple competing factors including: economic pressure, environmental sustainability, and human health. It introduces the perspective of corporate social responsibility (CSR) as a lens through which to view the dilemma. In this case study, the engineer must also make decisions that will affect their professional success in a new job and country.  

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 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:

Yasin is a pipeline design engineer who has been employed to manage the wastewater pipeline for MMC Textile Company in Gujarat. The company has a rapidly growing business contributing to one of India’s most important industries for employment and export. Yasin was hired through a remote process during the pandemic – he had never been to the industrial site or met his new colleagues in person until he relocated to the country. For 10 years, Yasin worked for the Water Services Regulation Authority in the UK as a wastewater engineer; this is the first time he has been employed by a private company and worked within the textile industry.

The production of textiles results in highly toxic effluent that must be treated and disposed of. A sludge pipeline takes wastewater away from MMC’s factory site and delivers it to a treatment plant downstream. On arrival at MMC, Yasin undertakes an initial inspection of the industrial site and the pipeline. He conducts some testing and measurements, then reviews the company’s documents and specifications related to the pipeline. This pipeline was built 30 years ago when MMC first began operations. In the last five years, MMC has partnered with a fast fashion chain and invested in advanced production technologies, resulting in a 50% increase in its yearly output. Yasin soon realises that as production has increased, the pipeline sometimes carries nearly double its registered capacity. Yasin was hired because MMC’s managers were aware that the pipeline capacity might be stretched and needed his expertise to develop a solution. However, Yasin suspects they are unaware of the real extent of the problem, and is nervous about how they will react to confirmation of this suspicion. Yasin is due to provide an informal verbal report on his initial inspection to the factory managers. This will be his first official business meeting since arriving in India.

 

Optional STOP for questions and activities:

1. Discussion: Although Yasin is a qualified and experienced engineer, what professional challenges might he encounter at MMC?

2. Discussion: What preparation does Yasin need to make for this informal meeting? What data or evidence should he present?

3. Activity: Role-play Yasin’s first meeting with the factory managers.

4. Activity: Research the environmental effects of textile production and / or India’s policies on textile waste management.

 

Dilemma – Part one:

At the meeting, Yasin is tasked with developing a menu of proposals to mitigate the problem. The options he puts forward include retrofitting the original pipeline, replacing it with a new one, eliminating the pipeline entirely and focusing on on-site water treatment technology, as well as other solutions. He is directed to consider the risks and benefits of the alternatives. These include the economic burdens, both the cost of the intervention as well as the decline in production necessitated while the intervention takes place, and the environmental consequences of action or inaction.  

During his research, Yasin discovers that informal housing has sprung up in the grey zone between the area’s formal zoned conurbation and the MMC industrial site. This is because there is little local regulation or enforcement as to where people are allowed to erect temporary or permanent dwellings. He estimates that there are several thousand people living in impoverished conditions on the edges of MMC’s property. Indeed, many of the people living in the informal settlement work in the lowest-skilled jobs at the textile factory. The informal settlement is located around a well that Yasin suspects may be polluted by effluent that seeps into the soil and groundwater when the pipeline overflows. He can find no information in company records about data related to this potential pollution.

 

Optional STOP for questions and activities:

1. Discussion: Does Yasin have a responsibility to do anything about the potential groundwater pollution at the informal settlement?

2. Discussion: Should Yasin advocate for the solution with the lowest cost?

3. Activity: Practise problem definition. What are the parameters and criteria Yasin should use in defining the issues at stake? What elements of the problem is he technically or ethically obligated to resolve? Why?

4. Activity: Create a tether diagram mapping the effects of each potential solution on the company, the local people, and the environment.

5. Activity: Undertake a technical activity in the areas of chemical, civil, manufacturing and / or mechanical engineering related to groundwater pollution.

 

Dilemma – Part two:

As Yasin learns more about MMC, he discovers that as the company grew rapidly in the last five years,  and has boosted its CSR initiatives, MMC started a programme to hire and upskill local labourers and began a charitable foundation to make donations to local schools and charities. For these activities, MMC has recently received a government commendation for its community commitments. Yasin is concerned about how to make sense of these activities on the one hand, and the potential groundwater contamination on the other. He speaks to his supervisor about MMC’s CSR initiatives and learns that company directors believe that their commendation will pave the way for an even better relationship with the government and perhaps enable a favourable decision on a permit to build another textile factory site nearby. At the end of the conversation, his supervisor indicates that if a new factory is built, it will need a chief site engineer. “That position would be double your current salary,” the supervisor says, “a good job on fixing this pipeline situation would make you look like a very attractive candidate.” Yasin is due to formally present his proposal about the pipeline next week to the factory manager and company directors.

 

Optional STOP for questions and activities:

1. Discussion: How should Yasin respond to the suggestion of a job offer?

2. Discussion: Should Yasin report any of MMC’s actions or motivations to an external authority?

3. Activity: Research CSR and its ethical dimensions, both in the UK and in India.

4. Activity: Undertake a technical activity in the areas of chemical, civil, manufacturing and / or mechanical engineering, related to pipeline design and flow rates.

5. Activity: Debate whether or not Yasin should become a whistleblower, either about the groundwater pollution or the job offer.

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 AHEP4 here and navigate to pages 30-31 and 35-37.

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?
