Rather than replacing skilled professionals, the guests discuss where AI can eliminate repetitive work, improve documentation, assist engineering teams, and help contractors make faster, more informed decisions, while emphasizing that human expertise, accountability, and judgment remain irreplaceable.</p><p>The group shares practical stories from the field, discussing commissioning, change orders, project coordination, design reviews, communication between trades, and how small decisions made early in a project often determine whether construction finishes smoothly or becomes an expensive problem later.</p><p>Packed with practical lessons for engineers, contractors, project managers, architects, manufacturers, and business leaders, this episode demonstrates that the best projects aren&#8217;t built by better drawings alone; they&#8217;re built through better communication, collaboration, and continuous learning.</p><div class="pullquote"><p><strong><span data-color="#cb48c6" style="color: rgb(203, 72, 198);">&#8220;Construction doesn&#8217;t fail because people stop caring, it fails when communication breaks down.&#8221;</span></strong></p></div><h2><strong>Keywords</strong></h2><p>Construction management, construction technology, AI in construction, engineering leadership, project management, HVAC, plumbing, mechanical engineering, electrical engineering, commissioning, change orders, construction collaboration, engineering communication, construction productivity, contractor coordination, digital transformation, construction innovation, building design, field engineering</p><div class="pullquote"><p><strong><span data-color="#cb48c6" style="color: rgb(203, 72, 198);">&#8220;AI should make engineers and contractors better, not replace them.&#8221;</span></strong></p></div><h2><strong>Takeaways</strong></h2><ul><li><p>Most construction failures originate from communication breakdowns rather than technical incompetence.</p></li><li><p>Engineers, contractors, and manufacturers deliver better outcomes when they collaborate early instead of working in isolation.</p></li><li><p>AI is most valuable when it removes repetitive administrative work while allowing professionals to focus on engineering judgment.</p></li><li><p>Strong relationships between field teams and design teams reduce costly change orders and project delays.</p></li><li><p>Real-world field experience often provides context that drawings and specifications cannot capture.</p></li><li><p>Commissioning and quality assurance should be viewed as investments, not project expenses.</p></li><li><p>The future of construction belongs to professionals who combine technical expertise with communication, adaptability, and emerging technology.</p></li></ul><div class="pullquote"><p><strong><span data-color="#cb48c6" style="color: rgb(203, 72, 198);">&#8220;The best projects happen when everyone solves the same problem instead of protecting their own scope.&#8221;</span></strong></p></div><h2><strong>Chapters</strong></h2><ol><li><p>Welcome to Extra Mile</p></li><li><p>Meet Bo Hamrick and Jason Breeden</p></li><li><p>Why Construction Projects Really Go Wrong</p></li><li><p>The Communication Gap Between Design and Field</p></li><li><p>Engineers, Contractors, and Shared Responsibility</p></li><li><p>AI&#8217;s Practical Role in Construction</p></li><li><p>Commissioning, Coordination, and Quality Control</p></li><li><p>Learning From Mistakes on Real Projects</p></li><li><p>Building Better Relationships Across the Industry</p></li><li><p>Final Thoughts</p></li></ol><div class="pullquote"><p><strong><span data-color="#cb48c6" style="color: rgb(203, 72, 198);">&#8220;Experience isn&#8217;t just knowing the answer, it&#8217;s knowing which questions to ask.&#8221;</span></strong></p></div><h2><strong>Where to Find Bo Hamrick</strong></h2><p><a href="https://www.linkedin.com/in/bo-hamrick-78a305159/?lipi=urn%3Ali%3Apage%3Ad_flagship3_profile_view_base_contact_details%3BY1vIGedaQiy6VkcZsf1QJQ%3D%3D">LinkedIn</a> &#183;

As both a practicing engineer and technology leader, he explains how computer vision, drones, 360&#176; site capture, large language models, and machine learning are beginning to transform structural inspections, parking garage maintenance, and engineering workflows.</p><p>Rather than focusing on AI hype, the conversation examines where artificial intelligence genuinely creates value, and where it still falls short. The trio discusses why AI can identify cracks, corrosion, and construction defects, but why determining the <em>root cause</em> of those defects still requires engineering judgment built from years of field experience.</p><p>The discussion expands beyond technology into the economics of engineering. They explore why engineering firms have historically struggled with low margins, how AI could reshape productivity instead of simply reducing fees, and why firms that embrace AI early may gain a lasting competitive advantage.</p><p>The episode also tackles the growing problem of AI &#8220;gurus&#8221; entering construction without domain expertise. Nick argues that engineers, not software influencers, must train the next generation of AI systems, because only practicing professionals understand the nuances, constraints, and real-world context behind engineering decisions.</p><p>Along the way, the conversation covers computer vision for inspections, drone mapping, AI-assisted commissioning, prompt injection, context engineering, hallucination detection, digital twins, infrastructure maintenance, engineering education, professional licensing, and what future engineers must learn to remain valuable in an AI-driven industry.</p><p>Packed with practical examples, thoughtful debate, and real-world engineering stories, this episode offers a grounded look at how artificial intelligence is changing engineering, not by replacing professionals, but by amplifying those who know how to use it.</p><div class="pullquote"><p><strong>&#8220;AI can tell you what the defect is.

Davis and Andrew share how they built HVAKR as practicing engineers solving real industry problems, why AI has dramatically accelerated software development, and how modern engineering teams are using AI to prototype, refactor, test, and ship features faster than ever before.</p><p>The conversation explores how AI is reducing the cost of experimentation, making software architecture easier to evolve, and allowing developers to compare multiple solutions instead of debating them endlessly. Kenneth also shares how PermitZIP uses AI-generated meeting transcripts, software agents, and automated workflows to accelerate internal product development, offering a practical look at what AI-native engineering teams already look like today.</p><p>Beyond technology, the trio tackles a much bigger question: if technical knowledge becomes universally accessible through AI, what will distinguish great engineers? They argue that judgment, communication, trust, reputation, and the ability to simplify complex ideas may soon become more valuable than technical expertise alone. The discussion also examines how AI could reshape traditional consulting, SaaS pricing models, engineering workflows, and even the future of hourly billing.</p><p>The episode closes with an entertaining deep dive into HVAC engineering, psychrometrics, indoor air quality, refrigeration fundamentals, and the engineering culture that inspired HVAKR, along with a glimpse into how AI-generated music is finding its way into engineering companies.</p><p>Thought-provoking, practical, and filled with real-world examples, this episode is a fascinating exploration of what happens when AI makes expertise more accessible, and why the most valuable human skills may be the ones machines can&#8217;t commoditize.</p><div class="pullquote"><p><strong>&#8220;Technical skills have become a commodity.&#8221;</strong></p></div><h2>Keywords</h2><p>Artificial Intelligence, AI in Engineering, Engineering Innovation, Software Development, HVAKR, PermitZIP, Workflow Automation, AI Coding, Engineering Leadership, Digital Transformation, Engineering Productivity, Future of Work, SaaS, Product Development, User Experience, AI Agents, Vibe Coding, HVAC Engineering, Professional Development, Technology Strategy</p><div class="pullquote"><p><strong>&#8220;I&#8217;m not worried about the cost of AI.

every client, person, and project &#8212; built so the team&#8217;s attention automatically goes where it earns the most.</p><p><strong>Every client carries two numbers.</strong> Credit (do they pay well, take fee and scope conversations gracefully, and are they good to work with &#8212; built from payments, invoice aging, email and call tone, and what our own team says privately) and Health (is the relationship warm and active &#8212; it decays a little every quiet day and recovers when we actually talk to them). Credit is <strong>uncapped</strong>: a client who pays four invoices the same day visibly pulls ahead of one who&#8217;s merely fine. Health stays 0&#8211;100.</p><p><strong>Every person carries a warmth number</strong> (0&#8211;100), and <strong>every project carries a risk number</strong> built from the knowledge graph &#8212; open questions nobody answered, commitments we owe, risk flags, a struggling client, and cold people woven through the job. Old questions fade out of the score instead of inflating it forever, and a cold person tied to many of our jobs counts more than a one-job annoyance.</p><h2><strong>T</strong>he highest-credit clients whose health is slipping, with whom we have the largest book of work, surface first &#8212; and within those clients, their most at-risk projects rise to the top.</h2><p><strong>Three rules keep it trustworthy.</strong> Every signal counts exactly once (no double-scoring). Conversations attach to a <em>project</em> first, and the project decides which client benefits &#8212; calling a third party like an architect no longer blindly credits whoever they&#8217;re globally linked to. And the AI only ever <em>proposes</em>; nothing moves a score from a knowledge-graph suggestion until a human accepts it, and every number is explainable and correctable from the screen it appears on.</p><p><strong>Every dial is configurable</strong> at <code>/settings/clients/score-settings</code>, every change is audited, and build-time tripwires plus SQL regression tests keep anyone &#8212; human or AI &#8212; from quietly reading scores from the wrong place or re-introducing old math.</p><h2>Paying early is rewarded.</h2><div class="captioned-image-container"><figure><a

because engineering firms are full of context that disappears. Gathering the right information when you need it on a complex project has an impedance mismatch problem in our industry.</p><p>A project is not just a folder. It is a messy web of people, clients, contractors, emails, meetings, decisions, site visits, open questions, promises, risks, and history. Most firms carry that in people&#8217;s heads until someone is busy, out sick, leaves, or just forgets. Then everyone starts digging through email like archaeologists.</p><p>That is the problem we all are trying to fix. Procore probably did the first best job at helping to solve that. But now we have new frontier models that are making personal in-house Procore a reality for everyone with a Codex or Cowork subscription. </p><h2>Our knowledge graph went live a couple months ago.</h2><p>And it is already starting to change how we look at projects. It pulls together the normal trail of work: emails, meetings, project records, people, companies, documents, open questions, commitments, and risk flags.</p><p>One project I keep coming back to is a complicated single family mega mansion on the beach. In the graph, you can see the project sitting inside a web of people, emails, meetings, documents, and unresolved issues. Our knowledge graph already had the information shown in image below (risk flags, open questions, open commitments). We are just associating a configurable point system to each of those. And calculating the risk for the project.</p><div class="captioned-image-container"><figure><a class="image-link image2" target="_blank" href="https://substackcdn.com/image/fetch/$s_!qQut!,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F6a398b09-e4c6-437a-bfb3-66c02447d8f5_2420x584.png" data-component-name="Image2ToDOM"><div class="image2-inset"><picture><source type="image/webp" srcset="https://substackcdn.com/image/fetch/$s_!qQut!,w_424,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F6a398b09-e4c6-437a-bfb3-66c02447d8f5_2420x584.png 424w, https://substackcdn.com/image/fetch/$s_!qQut!,w_848,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F6a398b09-e4c6-437a-bfb3-66c02447d8f5_2420x584.png 848w, https://substackcdn.com/image/fetch/$s_!qQut!,w_1272,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F6a398b09-e4c6-437a-bfb3-66c02447d8f5_2420x584.png 1272w, https://substackcdn.com/image/fetch/$s_!qQut!,w_1456,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F6a398b09-e4c6-437a-bfb3-66c02447d8f5_2420x584.png 1456w" sizes="100vw"><img src="https://substackcdn.com/image/fetch/$s_!qQut!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F6a398b09-e4c6-437a-bfb3-66c02447d8f5_2420x584.png" width="1456" height="351" data-attrs="{&quot;src&quot;:&quot;https://substack-post-media.s3.amazonaws.com/public/images/6a398b09-e4c6-437a-bfb3-66c02447d8f5_2420x584.png&quot;,&quot;srcNoWatermark&quot;:null,&quot;fullscreen&quot;:null,&quot;imageSize&quot;:null,&quot;height&quot;:351,&quot;width&quot;:1456,&quot;resizeWidth&quot;:null,&quot;bytes&quot;:null,&quot;alt&quot;:null,&quot;title&quot;:null,&quot;type&quot;:null,&quot;href&quot;:null,&quot;belowTheFold&quot;:true,&quot;topImage&quot;:false,&quot;internalRedirect&quot;:null,&quot;isProcessing&quot;:false,&quot;align&quot;:null,&quot;offset&quot;:false}" class="sizing-normal" alt="" srcset="https://substackcdn.com/image/fetch/$s_!qQut!,w_424,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F6a398b09-e4c6-437a-bfb3-66c02447d8f5_2420x584.png 424w, https://substackcdn.com/image/fetch/$s_!qQut!,w_848,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F6a398b09-e4c6-437a-bfb3-66c02447d8f5_2420x584.png 848w, https://substackcdn.com/image/fetch/$s_!qQut!,w_1272,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F6a398b09-e4c6-437a-bfb3-66c02447d8f5_2420x584.png 1272w, https://substackcdn.com/image/fetch/$s_!qQut!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F6a398b09-e4c6-437a-bfb3-66c02447d8f5_2420x584.png 1456w" sizes="100vw" loading="lazy"></picture><div></div></div></a></figure></div><p>I can click to see the flags.

We&#8217;re actively monitoring, reseraching, and fine tuning how it works and what is classifies. Some signals are stale. Some things get counted wrong. Some relationships need cleanup. But even that is useful because now the mess is visible.</p><p>We are learning that emails, meetings, calls, comments, and project records should not all be treated the same. A one-hour meeting probably tells you more about project risk than a random email reply. A stale open question should not hurt a project forever. A client should not automatically get blamed for chaos caused by a contractor. A person with influence across five risky projects matters more than someone who was difficult once and is no longer active in the market.</p><h2>PermitZIP is trying to make high-quality MEP engineering work on smaller commercial projects. </h2><p>That means we deal with tight budgets, fast timelines, imperfect information, and a lot of coordination gaps. Those jobs can go sideways quickly if the firm is only reacting to inbox noise. We&#8217;re also dealing with a larger-than-average population of lower experienced players with expectations that are completely unrealistic (huge risk for everyone involved).</p><p>The graph gives us another way to ask better questions:</p><ul><li><p>Which projects are quietly accumulating risk?</p></li><li><p>Which clients pay well but create a lot of drag?</p></li><li><p>Which contractors keep showing up near unresolved issues?</p></li><li><p>Which commitments are still open?</p></li><li><p>Which relationships are getting colder?</p></li><li><p>What is the chain of custody that lead to this decision?</p></li><li><p>Which project needs leadership attention before it becomes a fire?</p></li></ul><p>It helps our firm remember what happened, connect the dots, and point us toward what matters. </p><p>Technically speaking, it&#8217;s used to pre-feed our agents with that information so they can produce more accurate results (very important when each run might cost $10 or more).</p><h2>What I&#8217;d try if I worked at another firm</h2><p>First I would make sure I have a Claude Cowork or OpenAI Codex subscription with extra usage turned on. If I couldn&#8217;t get that, I would quit and find another job that would. What kind of company today doesn&#8217;t provide these resources to their engineers?<br><br>Anyway, I would not start by building a platform. I would pick one painful operating problem and model that.</p><p>For example: &#8220;We lose track of open questions after meetings.&#8221; Or &#8220;We do not know which clients are actually profitable until too late.&#8221; Or &#8220;Our PMs remember relationship history, but the company does not.&#8221; Or &#8220;We cannot see which projects are getting risky until someone is already mad.&#8221;</p><p>Take ten projects. Pull together recent emails, meeting notes, project folders, client names, companies, open issues, and payment history if you have it. Then ask how those things should connect.</p><p>I&#8217;d head straight to Claude or ChatGPT and prompt something like:</p><blockquote><p>We are a [type of firm] and we are struggling with [specific recurring problem]. We have project data spread across emails, meeting notes, folders, CRM records, and accounting. How could we use a knowledge graph to connect people, companies, projects, issues, risks, and decisions? What is the simplest version we could test this week without building a full platform?</p></blockquote><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img"

A difficult person tied to twenty other relationships is a business problem.</h2><p>And if they like you, great. That is a huge asset.</p><p>If they do not, pretending they do not matter is stupid.</p><p>And so now we&#8217;re finally getting a chance to measure the true cost of having an ego.</p><p>The old answer would have been easy.</p><p>&#8220;They are wrong.&#8221;</p><p>&#8220;They do not know what they are talking about.&#8221;</p><p>&#8220;They are recommending an illegal installation.&#8221;</p><p>Wouldn&#8217;t it be nice if being right mattered in business?</p><p>If it did, I could have retired at fourteen.

From replacing traditional Google searches with context-aware AI systems to automating repetitive engineering tasks and dramatically reducing project turnaround times, Nick shares real-world examples of how AI is quietly reshaping productivity across the construction and engineering industries.</p><p>The conversation also dives into why many organizations still hesitate to adopt AI despite its obvious advantages, the rise of performative &#8220;AI thought leadership&#8221; on social media, and the widening gap between people talking about AI and professionals actively using it every day. Kenny, Carter, and Nick discuss workflow automation, prompt engineering, engineering analysis, AI-assisted communication, and how younger professionals increasingly view AI tools as a normal part of modern work.</p><p>Along the way, the trio explores practical implementation strategies, the limitations of free AI tools, cybersecurity and prompt injection risks, and the growing expectation that engineers and consultants will become AI-literate in the near future. They also unpack how large language models are changing collaboration, research, and technical problem-solving inside engineering environments.</p><p>Fast-paced, highly relatable, and packed with actionable insight, this episode is an honest look at where practical AI adoption stands today, and how quickly the gap is growing between companies embracing these tools and those falling behind.</p><div class="pullquote"><p><strong>&#8220;Treat AI like a utility.&#8221;</strong></p></div><h2>Keywords</h2><p>AI in engineering, artificial intelligence, engineering workflows, AI

It survives by producing profitable output.</p><p>So the real question is:</p><blockquote><p>&#8220;How much sellable work did this cost create?&#8221;</p></blockquote><p>In software, the useful metric might start with dollars per shipped feature, then move to revenue, retention, or usage created by that feature.</p><p>In engineering and construction administration, it might be dollars per billable hour, dollars per RFI response, dollars per reviewed submittal, or dollars per completed revision.</p><p>The unit changes by industry.</p><p>The economic relationship does not.</p><h2>What this looks like for an AE firm?</h2><p>In the AE industry, a lot of engineering-side work is hourly.</p><p>That gives us a natural translation layer.</p><p>Human time becomes billable hours.</p><p>Now token consumption has to fit into that same model.</p><p>So we convert token spend into an effective hourly charge based on the person driving the agent. Tokens are not treated like some random software expense sitting off to the side. They are tied to the project work they support.</p><p>If an engineer is using agents to support construction administration work, those agents may help draft RFI responses, review submittals, generate revisions, research code paths, assemble context, or improve the depth and quality of a response.</p><p>The token spend is attached to the work.</p><p>And when the work is billable, the token spend can be translated back into revenue.</p><p>We do this now at PermitZIP. </p><p>At the time of writing this, <strong>our effective billing rate rate is around 6.7x our token spend.</strong></p><p>That is before fully measuring the productivity gain.</p><p>We have not yet fully quantified how many more RFIs, submittal reviews, revisions, or permit-related tasks one person can complete per day with the right agent workflow.</p><p>But we already know the token spend itself can produce a return when it is aimed at billable project work.</p><p>So the upside is not just:</p><div class="pullquote"><p>&#8220;We spent tokens and got work done.&#8221;</p></div><p>It is:</p><div class="pullquote"><p>&#8220;We spent tokens, billed against the work, improved the quality of the output, and may have expanded how much work one person can responsibly handle in a day.&#8221;</p></div><p>That is a very different economic picture.</p><h2>Humans bill linearly</h2><p>A human can only bill for the time they spend.</p><p>One hour of human time generally becomes one hour of billable time.</p><p>That is the traditional professional services model.</p><p>It scales linearly-ish.</p><p>This is one reason engineering firms often get low valuation multiples. Revenue is tightly coupled to headcount. More work requires more people. More people create more coordination, more management, more review, more overhead, more inefficiencies, and more risk.</p><p>AI changes the shape of that relationship.</p><p>The objective is fine tuning what one good human can drive.</p><blockquote><p>If one engineer spends an hour directing multiple agents across multiple projects, and those agents consume tokens that are tied to billable project work, that engineer may create more than one hour of billable value inside one clock hour.</p></blockquote><p>The right human, driving the right token spend, can produce and support more billable output than the human could produce alone.</p><h2>Some work is still cheaper with humans</h2><p>Some work is still cheaper with humans.</p><p>There are tasks where the prompting, validation, retrying, reviewing, and context loading cost more than just having a competent person do the work.</p><p>There are tasks where the model creates output quickly, but also creates just enough uncertainty that a human has to inspect everything anyway.</p><p>There are tasks where the token spend is real, the latency is annoying, the error rate matters, and the productivity gain is not enough to justify the workflow.</p><p>The economics are task-specific.</p><p>Engineers should understand this.</p><p>A tool is not good because it is technically impressive. It is good when it improves the system.</p><h2>Token cost does not map cleanly to labor cost</h2><p>We have been paying for token consumption for over a year now at PermitZIP.</p><p>It is already obvious that token cost does not map cleanly to human labor cost.</p><p>A dollar of human labor and a dollar of token spend do not produce the same kind of output.</p><p>Human labor is flexible, contextual, and slow.</p><p>Token-driven execution is fast, scalable, and uneven.</p><p>Both are non-deterministic in their own annoying ways.</p><p>Both are also confidently wrong more often than anyone wants to admit.</p><p>Humans get distracted, misunderstand priorities, get tired, miss details, defend bad assumptions, have egos, and have bad days.</p><p>Models hallucinate, over-answer, miss context, follow bad instructions too confidently, and sometimes create work that looks finished before it is actually useful.</p><p>Humans can notice when the request is dumb.</p><p>Models can brute force through structured work at a speed humans cannot touch.</p><p>Humans carry judgment.</p><p>Models carry throughput.</p><p>The return profile is not the same.</p><p>The advantage comes from blending human judgment with token-driven execution.</p><p>Outsized returns show up when the human knows how to direct the system.</p><h2>The budget shift.</h2><p>A lot of companies staffed up for human-only throughput.</p><p>Then they discovered that serious AI usage is not just a few subsidized subscriptions.</p><p>It is infrastructure.<br>It is token budget.<br>It is tooling.<br>It is evaluation.<br>It is workflow redesign.<br>It is people who know how to direct the system.</p><p>So now companies are rebalancing.</p><p>The layoffs we are seeing in tech are tied to this recalibration of production costs.</p><p>Budgets are moving from headcount-only operating models to blended systems where compute is a real cost center.</p><p>Companies usually cannot keep the same labor budget and simply add serious AI spend on top.</p><p>The money has to come from somewhere.</p><p>In many cases, that means fewer people, higher-leverage people, and more expensive tools.</p><p>That sounds harsh.</p><p>But supply and demand does not care about your feelings.</p><p>The operating model has changed.</p><p>The objective is whether the blended system produces more profitable output per dollar.</p><p>Ignore that at your own risk.</p><p>Being laid off today can mean getting locked out of the industry for a long time, because the cost of labor plus tokens is being reconciled in real time.</p><p>If you get booted from the human part of the system, do not assume another company is backfilling with more humans.</p><p>A lot of them are not.</p><p>They are making room for the tokens.</p><h2>The useful metric is profitable output per dollar</h2><p>This is where the conversation should be.</p><p>Not &#8220;AI is cheaper than humans.&#8221;</p><p>Not &#8220;AI is more expensive than humans.&#8221;</p><p>Those are lazy categories.</p><p>The useful questions are:</p><div class="pullquote"><p>What is the cost per useful unit of output?</p></div><p>Then:</p><div class="pullquote"><p>How much revenue or profit does that unit create?</p></div><p>For software, maybe that starts with cost per feature or features shipped per day. But the company still has to ask whether those features increase revenue, reduce churn, expand usage, or create enterprise value.</p><p>For AEC, maybe it is RFIs answered per day, submittals reviewed per day, revisions completed per day, or permits processed per week.</p><p>But the output has to connect to dollars.</p><p>Can it be billed?<br>Can it protect margin?<br>Can it reduce write-offs?<br>Can it improve cycle time?<br>Can it increase the amount of work one person can responsibly carry?</p><h2>Headcount is not the only scarce resource</h2><p>A lot of people are emotionally attached to headcount as the main measure of capacity.</p><p>More people means more output.</p><p>Sometimes.</p><p>But every manager who has actually run an engineering team knows headcount also creates coordination cost.</p><p>More reviews.<br>More meetings.<br>More onboarding.<br>More QA.<br>More HR.<br>More process.<br>More communication paths.<br>More places for work to hide.</p><p>AI has its own costs too.</p><p>Prompting.<br>Context management.<br>Tooling.<br>Evaluation.<br>Human review.<br>Bad outputs.<br>Security concerns.<br>Token burn.<br>Adoption.</p><p>Neither system is free.</p><p>The point is not to worship AI or defend headcount.</p><p>The point is to compare operating models honestly.</p><h2>The best AI systems are human-directed</h2><p>The strongest workflows I have seen are human-directed systems.</p><p>A person with judgment defines the task, constrains the output, reviews the result, and decides what matters.</p><p>The model handles the parts where speed, volume, pattern matching, drafting, restructuring, extraction, research, or iteration create leverage.</p><p>The return comes from designing a system where human judgment sits in the right place.</p><p>Many companies treat AI like a toy subscription or a magic labor replacement machine.</p><p>Both are bad operating models.</p><p>The better model is more uncomfortable:</p><p>Fewer people.<br>Better people.<br>More expensive tools.<br>More output.<br>More revenue per human.<br>More profit per dollar of total spend.</p><p>That is where this is going.</p><h2>Wishful thinking does not change the math</h2><p>If AI costs as much as a human engineer per year, that does not automatically make it expensive.</p><p>If it produces significantly more profitable output per dollar, it is cheap.</p><p>If it produces noise, rework, and review burden, it is expensive.</p><p>The annual spend alone does not answer the question.</p><p>Neither does the token bill.</p><p>Neither does the salary comparison.</p><p>The metric is the blended system:</p><p>Human cost plus token cost, measured against useful output, then measured against dollars generated.</p><p>That is basic engineering economics.</p><p>Software engineers should understand this better than almost anyone.</p><p>Cost. Throughput. Quality. Constraints. Revenue. Return.</p><p>That is what matters now.</p><p>That is what the industry is calibrating around.</p><p>Employees can ignore it.</p><p>Companies can ignore it.</p><p>Neither gets a special exemption from the math.</p><p>Tech is already laying people off while it figures out the right mix of humans, tools, and compute.</p><p>AEC is not immune to that.</p><p>If you are an employee and you want to pretend this is hype, fine.</p><p>Understand the risk.</p><p>If your job gets cut, the replacement may not be another person.</p><p>It may be a smaller team with better tools, bigger token budgets, and a different operating model.</p><p>Getting back in will be harder if your skills only fit the old model.</p><p>Maybe you are locked out for a few months.</p><p>Maybe a few years.</p><p>Maybe permanently if the work you used to do gets absorbed into the system and the industry stops hiring for it.</p><p>That is what happens when production costs get recalibrated.</p><p>If you run a company, the warning is just as direct.</p><p>Your competitors are doing this math too.</p><p>They are testing where humans matter, where agents work, where tokens replace labor, where quality improves, where margins expand, and where cycle time collapses.</p><p>Some of them will figure it out before you do.</p><p>They will produce more with less.</p><p>They will price differently.</p><p>They will hire differently.</p><p>They will carry more work per person.</p><p>They will generate returns you cannot match with a headcount-only model.</p><p>So measure the system honestly.</p><p>Human cost. <br>Token cost. <br>Useful output. <br>Revenue generated. <br>Margin protected. <br>Rework avoided. <br>Cycle time reduced.</p><p>The recalibration is already happening.</p><p>You can participate in it, or you can be priced by it.</p><div class="subscription-widget-wrap-editor" data-attrs="{&quot;url&quot;:&quot;https://www.thebptour.com/subscribe?&quot;,&quot;text&quot;:&quot;Subscribe&quot;,&quot;language&quot;:&quot;en&quot;}" data-component-name="SubscribeWidgetToDOM"><div class="subscription-widget show-subscribe"><div class="preamble"><p class="cta-caption">The Engineering Stack is a reader-supported publication.

From hanging off skyscraper building scaffolds to implementing automation into modern business workflows, he shares firsthand insight into how construction professionals are adapting, or struggling to adapt, to rapid technological change.</p><p>The discussion explores AI adoption in construction firms, why many experienced professionals remain hesitant to embrace AI tools, and how younger generations are increasingly being tasked with implementing digital transformation inside legacy organizations. Anthony and Kenny also dive into the growing role of large language models (LLMs), AI-powered communication, workflow automation, and the challenge of preserving institutional knowledge as the industry evolves.</p><p>Along the way, the trio unpacks the realities of information overload, managing hundreds of daily emails, AI-assisted marketing, and how tools like Canva, Buffer, and language models are quietly reshaping day-to-day business operations. They also discuss why AI is unlikely to replace experienced professionals outright, but instead may amplify expertise by allowing &#8220;unlimited seniors to unlimited juniors.&#8221;</p><p>Candid, practical, and highly relevant to anyone navigating the future of work, this episode is an honest look at the intersection of construction experience, workforce evolution, and AI-driven transformation.</p><div class="pullquote"><p><strong>&#8220;It&#8217;s physically impossible to answer a thousand emails a day.&#8221;</strong></p></div><h2><strong>Keywords</strong></h2><p>AI in construction, construction technology, digital transformation, construction industry, artificial intelligence, construction management, institutional knowledge, AI adoption, construction leadership, workforce transformation, business automation, LLMs, construction innovation, project management, future of work, AI tools, construction consulting, generational workforce shift, business development, manufacturing technology</p><div class="pullquote"><p><strong>&#8220;You need to integrate AI into your daily routine.

Spiro shares firsthand insights from decades in exterior restoration, including working on nationally recognized landmarks and navigating the risks that come with repairing aging structures at extreme heights.</p><p>The conversation explores the origins of modern facade safety laws, including how real-world tragedies led to regulatory changes that still shape building maintenance today. Spiro explains how restoration companies calculate risk, manage complex projects, and coordinate across multiple trades to keep buildings safe and operational.</p><p>Beyond construction practices, the discussion touches on emerging technology in the field, including how AI is beginning to support quantity takeoffs, submittal generation, and workforce tracking. The hosts and guest also explore the growing issue of fraudulent claims in construction, an expensive and widespread problem that impacts insurance costs, project planning, and industry sustainability.</p><p>From skateboarding down the ramps of the Guggenheim during late-night restoration work to overseeing large-scale facade rehabilitation projects, this episode highlights the technical, legal, and human challenges behind maintaining the buildings we rely on every day.</p><p>Practical, candid, and grounded in real-world experience, this episode offers valuable insight into

Eugene shares real-world concerns about protecting intellectual property while still leveraging the massive efficiency gains AI can provide.</p><p>Together, they explore the technical and philosophical implications of integrating AI into engineering workflows, from prompt injection risks and data privacy tradeoffs to the rise of local AI models designed to protect sensitive information. The group also examines how licensing laws may keep engineers legally responsible in an increasingly automated world, even as AI systems handle more design and coordination tasks.</p><p>Beyond AI, the discussion expands into broader industry shifts, how engineering business models could evolve, whether intellectual property will retain its value, and what lessons the music industry&#8217;s transition to digital distribution can teach the design and construction world.</p><p>The episode also highlights Eugene&#8217;s unique dual perspective as both a licensed structural engineer and architect, including his work performing high-rise inspections using rope access systems, sometimes hundreds of feet above ground level.</p><p>Thought-provoking, technical, and forward-looking, this episode offers a candid look at how engineers must adapt to protect their knowledge, maintain responsibility, and navigate the rapid evolution of AI-powered design workflows.</p><div class="pullquote"><p>&#8220;You unleash an AI&#8230; and now it has access to your intellectual property, the value of your business.&#8221;</p></div><h2><strong>Keywords</strong></h2><p>Artificial intelligence, AI security, intellectual property, AI in engineering, data privacy, prompt injection, engineering workflows, digital transformation, construction technology, structural engineering, rope access inspection, building inspections, engineering responsibility, AI risk management, Rand Engineering &amp; Architecture, PermitZIP, IIBEC conference, local AI models, engineering automation</p><div class="pullquote"><p>&#8220;Maybe there is no IP anymore&#8230; maybe it&#8217;s all available to everybody.&#8221;</p></div><h2><strong>Takeaways</strong></h2><ul><li><p>AI tools can unlock massive productivity gains&#8212;but they also introduce new risks around intellectual property exposure.</p></li><li><p>Combining private data, internet access, and external inputs creates security vulnerabilities such as prompt injection risks.</p></li><li><p>Local AI models may become a key solution for protecting sensitive engineering data.</p></li><li><p>Engineers will likely remain legally responsible for decisions&#8212;even as AI automates more workflows.</p></li><li><p>Business models in engineering may shift, with value moving from drawings to real-time decision support.</p></li><li><p>Intellectual property may become harder to protect as digital tools accelerate data sharing and duplication.</p></li><li><p>Real-time feedback from AI can significantly improve decision validation and reduce long-term design risk.</p></li></ul><div class="pullquote"><p>&#8220;What if drawings become the commodity, and answers become the product?&#8221;</p></div><h2><strong>Chapters</strong></h2><ol><li><p>Welcome and Guest Introduction</p></li><li><p>Meet Eugene Gurevich: Structural Engineer and Architect</p></li><li><p>Engineering Hierarchies and the &#8220;Pencil Tip&#8221; Concept</p></li><li><p>AI Adoption Challenges in Engineering Firms</p></li><li><p>Understanding Prompt Injection and Data Security Risks</p></li><li><p>Protecting Intellectual Property in AI Workflows</p></li><li><p>Local AI Models vs Cloud-Based Systems</p></li><li><p>The Future of Engineering Responsibility</p></li><li><p>Business Model Shifts in Design and Construction</p></li><li><p>Lessons from the Music Industry&#8217;s Digital Transformation</p></li><li><p>High-Rise Rope Access Inspections and Real-World Risks</p></li><li><p>Final Thoughts on the Future of Engineering in an AI Era</p></li></ol><div class="pullquote"><p>&#8220;You can&#8217;t sue a bunch of GPUs if a building collapses.&#8221;</p></div><h2><strong>Where to Find Eugene Gurevich</strong></h2><p><a href="https://randpc.com/">Rand Engineering &amp; Architecture</a> &#183; <a href="https://www.linkedin.com/in/eugene-gurevich-pe-aia-leed-ap-b620a825/?lipi=urn%3Ali%3Apage%3Ad_flagship3_profile_view_base_contact_details%3Bm%2FaIl4tARyyQW1HRVdKj3A%3D%3D">LinkedIn</a></p><div><hr></div><h2><strong>Where to Find The Blueprint Tour</strong></h2><p><a href="https://www.youtube.com/@theblueprinttour">YouTube</a> &#183; <a href="https://www.tiktok.com/@theblueprinttourhttps://www.tiktok.com/@theblueprinttourhttps://www.tiktok.com/@theblueprinttour">TikTok</a> &#183; <a href="https://thebptour.com/">TheBPTour.com</a><br><a href="https://x.com/PermitZIPhvac">Kenneth Shultz (Host)</a> &#183; <a href="https://x.com/PermitZIPelec">Carter Huddleston (Host)</a></p>]]></content:encoded></item></channel></rss>
