In this case study, we explore the integration of two Generative AI (GenAI)-based writing assignments into a senior-level civil engineering design course. The goals of this study are to (i) cultivate a culture of AI among students, (ii) enable them to critically evaluate the GenAI outputs and their limitations and (iii) assess and discuss the ethical use of AI within the civil engineering profession. Twenty-seven students participated in the two writing assignments: one requiring the use of AI and the other permitting its optional use. The first assignment (homework) encouraged students to explore the design of steel structures by selecting a structure of their choice and generating a one-page write-up using GenAI. We asked the students to critically assess the AI-generated output, verify facts, and document their interactions with the AI tool by providing all prompts and reflecting on their experiences. In the second assignment, a take-home quiz, we asked the students to read and analyze two articles. The first article discusses the implications of GenAI in civil engineering and architecture professions [1], while the second article explores the integration of human and artificial intelligence in civil engineering. In their analysis, we asked the students to discuss how GenAI could enhance efficiency and safety in the field, as well as the ethical challenges associated with GenAI use. In both assignments, they were prompted to document their use of GenAI, modifying the AI-generated content while composing a reflective analysis of the tool's influence on their learning. The results of a qualitative analysis of students' responses indicated common themes regarding their perceptions of GenAI use both in learning and in the profession. Many students expressed curiosity about GenAI's future potential in civil engineering design while acknowledging the importance of critically assessing AI outputs. Key themes included the balance between AI-assisted creativity and as well as concerns about the reliability of AI-generated information. We believe the forward-thinking approach to GenAI in engineering education can foster an innovative learning environment favorable to experimentation with these tools. The insights gained from this case study highlight the importance of integrating GenAI into the civil engineering curriculum. We believe giving such an opportunity in the engineering classroom [3] will help prepare students to use GenAI responsibly and effectively in their profession upon graduation.
