new trends, new techniques and current industry issues

Iwas part of a conversation recently among a group of practitioners where someone wondered about what was studied in an Architectural Engineering (ArchE) program. Earning a Bachelor’s Degree in Architectural Engineering myself, this curiosity surprised me. After all, I had presumed, in the several decades since graduating, Architectural Engineering had surely become ubiquitous in the profession in which most of us practice. But it prompted me to realize it had been some time since I thought about the attitude that persisted at the time of my graduation: Engineers hear the word Architect, and Architects hear the word Engineer – therefore, someone with such a degree did not belong to either group. In a quick internet search, I found that only 37 universities in the U.S. offer a Bachelor’s of Science Degree in Architectural Engineering, 9 offer Master’s Degrees and, surprisingly, only one offers a Doctoral degree. In comparison, 265 universities offer a B.S. degree in Civil Engineering, and Architectural Engineering nearly 190 with M.S. and 120 with Ph.D. programs. With this significant disparity in Colleges and What, exactly, is it? Universities offering the B.S. ArchE degree or higher, I had to admit that maybe the Architectural By Stephen P. Schneider, Ph.D., Engineering degree was not as commonplace as I P.E., S.E. had come to believe. In general, only an academic department can confer a degree; thus, an Architectural Engineering Department is recognized by the College of Engineering as an independent academic unit. Among the many criteria required to be an academic department are an authorized faculty and a designated course of study leading to an undergraduate or graduate degree. While Steve Schneider is a Senior Project the curriculum can often overlap with the CE Manager for BergerABAM, Inc. program, it is neither a discipline within CE or He holds a B.S.ArchE degree a discipline within Architecture – Architectural from the University of Colorado, Engineering is a recognized field of study on Boulder, an M.S and a Ph.D. its own. in Civil Engineering from The courses of study within ArchE can be the University of Washington, grouped into 3 general categories: Seattle, and practices structural • Structural, engineering in the Portland, OR • Environmental & Building Energy, and area. Steve is also a member of the • Infrastructure & Construction STRUCTURE magazine Editorial Management. Board. He can be reached at It is perhaps Environment & Building Energy steve.schneider@abam.com. courses and approved electives that distinguish the B.S. ArchE degree over one in Civil Engineering. Environment & Building Energy courses focus on the building environment, having coursework that might include: lighting & electrical systems, HVAC systems, plumbing & fire safety, acoustics, solar energy, renewable energy, and sustainability. ArchE graduates with this emphasis have gone on to successful careers in architectural lighting for building interiors and exteriors, energy design of the building envelope, and renewable energy resources, to name a few. Electives in the ArchE curriculum focus on architectural considerations and are the primary link to a course of study in Architecture. These classes are often taught in conjunction with, and by the faculty in, the Architecture program. Coursework can include: architectural history, architectural appreciation, and introductory architectural design courses where the student might go through the full development and design of a building from an architect’s perspective. Each topic likely needs a two-course sequence to complete. Architectural history, for instance, is the study of architectural styles throughout the ages and requires a full academic year to cover the topic well. As for the coursework that emphasizes Structures or Construction Management, many of the classes needed to fulfill these requirements are the same classes taken by CE students with a similar emphasis. In essence, for certain classes there is no difference between the ArchE and CE programs. As for my ArchE experience, my emphasis was structural engineering. The curriculum was an exceptional way to study the design and construction of the built environment. Because of my interest in architecture, this was better for me than what was offered through a CE program which requires classes in transportation, environmental sciences, and the like. And the program afforded me the flexibility to focus on structural engineering. As an undergraduate, I took graduate-level classes in structural dynamics, framed structural analysis and an introductory course in finite elements. I was taking these classes with a few of my ArchE classmates and CE students studying for their M.S. degree. So… Architect or Engineer? Undoubtedly, ArchE is an engineering program. Architects focus on building layout and aesthetics while the Architectural Engineer will impact its design, function, and construction. If your work is primarily structural engineering and you are looking for a new hire, you should not discount someone with an ArchE degree because of a lack of understanding about their educational background. If your client base is predominantly architects, someone with an ArchE degree can be an excellent fit.▪

The Logic of Ingenuity

Part 4: Beyond Engineering

By Jon A. Schmidt, P.E., SECB

This series began with the premise that the “logic of inquiry” in science, as expounded by Charles Sanders Peirce, also serves as a “logic of ingenuity” in engineering. I would like to revisit this notion by examining the aim of inquiry as asserted by Peirce in the title of one of his most famous essays, “The Fixation of Belief” (www.peirce.org/writings/p107.html). It appeared originally in the November 1877 issue of Popular Science Monthly as the first of six articles under the heading, “Illustrations of the Logic of Science,” and subsequently as CP 5.358-387 and EP 1.109-123. According to the text:

Doubt is an uneasy and dissatisfied state from which we struggle to free ourselves and pass into the state of belief; while the latter is a calm and satisfactory state which we do not wish to avoid … The irritation of doubt causes a struggle to attain a state of belief (CP 5.372-374, EP 1.114). The first part of this quote indicates how the second part can be generalized: The irritation of dissatisfaction causes a struggle to attain a state of satisfaction. This happens to be exactly what Henry Petroski described as the governing principle of all invention and innovation in his 1992 book, The Evolution of Useful Things: “… the form of made things is always subject to change in response to their real or perceived shortcomings, their failures to function properly” (p. 22). He clearly had physical artifacts in mind, but the basic idea pertains to anything produced by humans – including scientific theories. In other words, contrary to the common (but misleading) definition of engineering as “applied science,” science is – at least in some ways – analogous to a discipline of engineering. Some might dispute this by claiming that science, unlike engineering, is primarily in the business of finding truth. Peirce agreed when discussing “science” as a collaborative endeavor by a large community of investigators working together over an extended period of time. However, for a single individual under ordinary conditions: … the sole object of inquiry is the settlement of opinion. We may fancy that this is not enough for us, and that we seek, not merely an opinion, but a true opinion. But put this fancy to the test, and it proves groundless; The Logic of Ingenuity The process of (abductively) creating a diagrammatic representation of a problem and its proposed solution, and then (deductively) working out the necessary consequences, such that this serves as an adequate substitute for (inductively) evaluating the actual situation.

for as soon as a firm belief is reached we are entirely satisfied, whether the belief be true or false (CP 5.375, EP 1.114-115). Therefore, truth is the goal of inquiry only in the long run, and only in the sense that our ongoing interaction with nature – what Peirce called the “Outward Clash” (CP 8.41-43, EP 1.233-234) – prevents us from ever being permanently satisfied with our beliefs by periodically confronting us with evidence that some of them are false. By contrast, the goal of ingenuity is something that we hope to achieve in the short term: solving a problem, typically despite incomplete knowledge and limited resources. Adapting Peirce’s phrasing once again: The irritation of uncertainty causes a struggle to attain a state of decision; or as he wrote in the subsequent article, “How to Make Our Ideas Clear” (www.peirce.org/writings/p119.html), “The final upshot of thinking is the exercise of volition” (CP 5.397, EP 1.129; 1878). This implies that the logic of ingenuity may be applicable to the contemplation of any potential activity that could be undertaken voluntarily. It thus extends beyond engineering, into the much broader domain of ethics. And yet, by his own admission, Peirce did not have much to say about that subject until relatively late in his career. In a 1903 lecture, he classified it with esthetics and logic as “The Three Normative Sciences” (CP 5.120-150, EP 2.196-207):

For normative science in general being the science of the laws of conformity of things to ends, esthetics considers those things whose ends are to embody qualities of feeling, ethics those things whose ends lie in action, and logic those things whose end is to represent something … That is right action which is in conformity to ends which we are prepared deliberately to adopt (CP 5.129-130, EP 2.200). Peirce came to see that logic is a form of ethics because thought is a form of conduct; and that self-control is essential to both thinking well and acting well because we cannot influence the past or the present – only the future. In another lecture later the same year, he posed the question, “What Makes a Reasoning Sound?” (EP 2.242-257) and answered it by explicitly drawing a parallel with what makes an action morally right. Daniel G. Campos, a philosophy professor at Brooklyn College of the City University of New York, summarized six stages identified by Peirce in a 2015 paper, “The Role of Diagrammatic Reasoning in Ethical Deliberation” (Transactions of the Charles S. Peirce Society, Vol. 51, No. 3, pp. 338-357): 1) Affirming ideals that together constitute a worldview and shape one’s character. 2) Establishing an intention to behave in accordance with those ideals. 3) Formulating rules of conduct, “practical maxims for what ought to be done in circumstances that fall under a more or less vague description.” 4) Making a resolution for how to act if and when a specific occasion arises that is foreseen through the use of “semiotic imagination – the ability to create and transform signs – guided by practical knowledge of what paths events may follow.” 5) Converting this resolution into a determination, an abiding disposition that is “capable of effectively guiding conduct.” 6) Engaging in a critical review of one’s actions in relation to all of the above, which produces approval or disapproval of the former – and sometimes revision of the latter. Peirce wrote of the fourth step, “This resolution is of the nature of a plan, or, as one might almost say, a diagram” (EP 2.246). Prompted by this hint, Campos suggested that each of the others is likewise analogous to an aspect of diagrammatic reasoning – although, in both cases, “we must keep in mind that this is a continuous process and that its various stages may be more or less emphatically experienced in different contexts.” In the same order as above:

1) Ideals correspond to a set of “framing hypotheses” that comprise a representational system. 2) An intention corresponds to the purpose of the exercise. 3) Rules of conduct correspond to “heuristic[s] … that direct an inquirer to employ a certain method of solution depending on the general type of problem under investigation.” 4) A resolution corresponds to “a mathematical model that may be formulated and investigated abstractly but is intended to apply to a concrete state of things.” 5) A determination corresponds to the intellectual virtue of judgment that eventually emerges from “mathematical experience.” 6) Review corresponds to the observation of the results of diagram manipulation. This analysis aligns with my persistent claim that engineering is an especially systematic way of willing – if I am right, then the former’s distinctive reasoning process should be paradigmatic for the latter. However, contrary to the profession’s traditional reputation, this does not entail the use of a quantitative model in every instance. For example, rather than an abstract formalization, it might be – and in ethical scenarios, often is – constructed as a narrative instead. After all, engineering mostly deals with material phenomena, which Peirce conceptualized as “inveterate habits becoming physical laws” (CP 6.25, EP 1.293; 1891). The behavior of people, on the other hand, is always subject to change – our habits are far more malleable, which makes us far less predictable. Regardless, the key to success is having the ability to discern the significant aspects of reality and consistently capture them, before definitively selecting a way forward from among multiple viable options. The logic of ingenuity is thus itself a carefully cultivated habit that facilitates imagining possibilities, assessing alternatives, and choosing one of them to actualize – in engineering, in science, or in any other endeavor.▪ Jon A.
