51 - Stop Selling, Start Serving with Ken Harms

In an industry often defined by hard data and low bids, how do you actually win work without "selling out"? In this episode of Constructive, I sit down with Ken Harms, a construction industry veteran with over 40 years of experience, to discuss the transition from technical project management to the human side of business development. Ken recently authored the book, Building Trust and Winning Work, where he argues that winning work has less to do with the physical proposal and everything to do with how you show up for your clients and build authentic relationships. We dive deep into the "Doer-Seller" model, the psychological hurdles of trust, and why the phrase "stay in your lane" is a creativity killer for construction firms. Key Topics Covered:The Trust Hurdle: Why being likable and competent isn't enough if you break your word. Service over Selling: Shifting your mindset from "making a sale" to being of radical service to the client. The Power of Curiosity: Why you should walk into a client meeting with a legal pad and six questions instead of a glossy brochure. Coaching & Mentorship: Why even the best in the industry—like Steph Curry—still need a coach to stay on top of their game. AI in Construction: How to use AI as a force multiplier for research without losing the essential "face-to-face" human connection. Whether you're an APM looking to accelerate your career or a C-suite executive rethinking your corporate strategy, Ken’s insights offer a blueprint for winning work with integrity.

49 - A Case for Price Transparency - Buildplus

Are you "robbing Peter to pay Paul" just to keep your job sites running? In this episode, Seth sits down with Nick, co-founder of Buildplus, to discuss why the traditional construction cash flow model is broken—and why so many contractors are unknowingly operating like a Ponzi scheme.We dig into the messy reality of construction finance, from the "receipt in the cup holder" problem to the "napkin math" that passes for estimating today. Nick explains how Buildplus is using fintech and "Cost Plus" models to force radical transparency, eliminate client anxiety, and ensure every project stands on its own financial feet.If you’re tired of estimates that are "slop" and want to stop flying by the seat of your pants on high-end projects, this conversation is for you.In this episode, we cover:The Origin Story: How a builder bankruptcy sparked the idea for Buildplus.The "Ponzi" Trap: Why using Project A’s deposit to fund Project B is a ticking time bomb.Cost Plus vs. Fixed Fee: Why transparent pricing actually builds trust (and protects your profit).The "Receipt in the Cup Holder": Solving the chaos of expense tracking in the field.AI & The Future: Why current estimates are "BS made up on a napkin" and how AI might fix it.🔗 Connect with BuildPlus: Buildplus is a financial technology company and is not a bank. Banking services are provided by Core Bank, Member FDIC.Buildplus is not a FDIC insured institution and the FDIC’s deposit insurance coverage only protects against the failure of an FDIC insured depository institution.Website: https://buildplus.appContact: nicolas@buildplus.app💡 About Constructive:Constructive explores the intersection of technology and the Architecture, Engineering, and Construction (AEC) industry.

48-No Formwork, No Binders, No Limits - ImpactBuild

Is it possible to build a sustainable future using the very ground beneath our feet? In this episode of Constructive, we sit down with Dr. Lauren Vasey and Kunal, the minds behind the ETH Zurich spin-off impact.build. They are moving beyond traditional 3D printing to a method called "Impact Printing"—a process that shoots excavated earth at high velocities to create structural bonds without the need for cement or chemical additives.We dive into the technical breakthroughs that allowed them to print a two-meter wall in a single session, the mission to democratize construction through automation, and why saving the world requires a profitable business model.Key Topics Discussed:What is Impact Printing? How shooting material at high velocity creates bonding without binders like cement.The Problem with Extrusion: Why typical 3D printing struggles with height and how impact printing solves the "green strength" problem.Circular Architecture: Using 100% recyclable materials sourced directly from construction site excavation.High-Payload Robotics: Moving specialized tools from the lab to autonomous gantry machines on-site.The Future of Work: Why automation isn't replacing workers, but rather taking over the "dull, dirty, and dangerous" tasks of the industry.Global Scalability: Scaling micro-factories to regions like India to turn waste soil into luxury resorts.

47 - Stop Reporting the Fire, Start Preventing the Spark - InspectMind

Can AI catch the errors that humans physically can't?In this episode, we welcome back Aakash Prasad (CEO) and Shuangling Yin (CTO) of InspectMind.ai. Since our last conversation, they’ve made a massive pivot upstream—moving from documenting field issues to preventing them entirely before ground is broken.We dive into their new "AI Checker Agent," a tool that cross-references thousands of drawing sheets, specs, and code requirements to find logic gaps that cost millions. Aakash shares a case study where the agent caught a material mismatch that would have cost a contractor $2M in rework, and Shuangling breaks down why "chatbots" aren't enough for construction—you need agents that execute complex workflows on your behalf.In this episode, we cover:The Pivot: How a job site visit in Long Island changed the company’s entire direction.The "Impossible" Standard: Why checking architectural drawings against structural plans is nearly impossible for humans at scale.Agents vs. Chatbots: Why the industry needs "hair on fire" solutions, not just cool tech.Trust & Verification: How their AI cites every claim so engineers can verify, not just trust.Links:Check out InspectMind: www.inspectmind.aiConnect with Aakash and Shuangling on LinkedIn.
