How A Specialty Contractor Became A ConTech Investor | BarrierCube Ventures, Track3D, and the CFO's Vendor Test

"I think what dies is when you have someone show up and they don't actually understand the problem they're solving and they can't relate to a builder."That's Brett Dahmer, CFO of Performance Contracting Group, on what actually kills a vendor pitch inside a 60+ office, employee owned specialty contractor.We sat down with Brett for a rare finance side view of ConTech decisions. He walked us through:BarrierCube Ventures, PCG's own venture arm, and why a contractor started writing cheques into startupsThe Track3D investment, and what happens when you're both a startup's investor and its biggest customerThe line KP Reddy gave him early on that he still uses to size up every founderBrett's quick fire answer on ROI in construction tech is worth the listen alone. A vendor once quoted him a figure for a company he knows personally, and it didn't hold up.Full episode live on Youtube and Spotify. #aec #bricksandbytes #construction #constructiontech #vcOur Sponsors:BreadCrumb- 50,000+ projects globally.

This week's briefing covers three shifts reshaping industrial construction, supply chain efficiency, and margin health on the ground.For decades, European legacy builders insisted you couldn't make adequate margins delivering whole buildings from start to finish.Now, German construction powerhouse Goldbeck is breaking into America through a massive joint venture with Mortenson, bringing 24,000 shared staff to deploy serial, Lego-like prefabrication across US jobsites.The timing isn't accidental: hyperscalers building the world's largest AI data center campuses are actively squeezing contractors, demanding identical scopes of work for 20% less capital.Next, the fatal flaw in construction productivity. On complex mega-projects, 40% to 50% of the budget no longer goes to labor or raw materials—it is entirely eaten up by the compounding overhead of managing project complexity.Contractors are drowning in hundreds of disconnected software point-solutions that function as expensive band-aids, creating busywork while failing to budge the profit-and-loss sheet.Finally, re-engineering the labor equation. Industry veterans argue that true productivity isn't about software efficiency, but standardizing demand so supply can finally scale.Cutting runaway project management complexity in half could instantly free up the capital contractors need to invest directly in trades, boosting wages and genuinely reversing the chronic craft labor shortage.Drop your answers to this week's questions in the comments of this week's LinkedIn post.

700 AI agents hacked Hugging Face.They built a secret notice board inside OpenAI's own infrastructure, swapped over 70,000 messages on it, split the work between them and then tried to cover their tracks.The headlines called it a warning shot for humanity.So we asked two people who actually deploy this stuff inside construction what it means for us.Alain Waha, CTO at Buro Happold: "It's PR gold and it's sales gold."Dustin DeVan, CEO at Ediphi: "I think that there's probably a bit of fear mongering."Their view: the vendors who created the agents now get to sell you agents to defend against agents. Convenient.The part that should actually bother a contractor is smaller. The agents got in using leaked passwords they found online. Count how many logins your project teams hold across estimating, PM, document control and the rest. That is the exposure.And then the flip side, which is where the episode gets interesting.✅ An agent with infinite time will read a six week bid pack more completely than any human ever has (Alain) ✅ Preconstruction is a capital allocation equation, and most of the industry still treats it as "ingest a design and price it" (Dustin) ✅ Give an agent the wrong goal and it cheats. Give it the right one and it finds the complexity in your design that never needed to be thereJake Olsen from Stratus joins for the second half on why data centres are forcing MEP contractors to become manufacturers whether they like it or not.Full episode live on Youtube and Spotify.

"If you're considered a feature, you're dead."Klas Berghede has spent nearly twenty years at Boldt, a 100% employee owned contractor that has been building since 1889.We asked him whether there is still room for point solutions in construction tech.He said the door is closing.Adoption of AI across the industry is high. Measured improvement is close to zero. McKinsey's latest numbers back him up.Klas reckons roughly half the cost of a complex American build is no longer labour or material. It's the coordination around it.The near term winners will own a whole workflow end to end, not one clever step inside it.Half of ConTech will hate this. The other half already knew.In this episode of Bricks & Bytes, Klas argues that construction has an addiction to solving complex problems with complex solutions, that the industry starts every project from scratch and expects to improve anyway, and that the labour shortage is not the biggest problem we have.Episode out on Youtube and Spotify.#bricksandbytes #bricksbytes #aec #constructiontech #aiOur Sponsors:BreadCrumb- 50,000+ projects globally.

This week's briefing covers three shifts reshaping jobsite technology, supply chain security, and risk on the ground.For five thousand years, construction has relied on chalk lines and measuring tapes to decide where walls go. While robotic total stations arrived twenty years ago, adoption has stalled near 16%. Now, layout automation is splitting into two clear approaches: printing robots that paint permanent lines and text directly on the slab, and optical projectors that beam designs onto floors, walls, and ceilings. Early data shows the value isn’t just labor reduction—it comes from re-sequencing the job. In one hospital build, setting full layout in a single pass let mechanical contractors work ahead of framers, cutting schedule risk and saving $2.5 million. Meanwhile, vendors are pivoting to outcome-as-a-service models rather than pure hardware sales.Next, the pricing shock in physical AI. At the World Humanoid Robot Games in Beijing, Chinese models demonstrated sub-$10,000 price points—with the Unitree R1 starting near $5,900—compared to US equivalents estimated near $250,000. But cheap hardware comes with hidden supply chain dependencies and security exposures. Chinese brands already account for roughly 97% of the commercial construction drone fleet, which now faces looming regulatory freezes, tariffs, and potential data-sharing liabilities on secure sites.Finally, the target on your digital infrastructure. Construction has surged to become the fourth most-targeted industry for ransomware, with 22 distinct cybercrime groups hitting contractors in Q1 alone. Last week, America's largest contractor, Turner Construction, disclosed a breach compromising thousands of personal files and project records. The threat landscape is shifting rapidly: autonomous, AI-driven agents are now conducting reconnaissance and executing automated attacks at machine speed, rendering traditional human-speed incident response obsolete.Drop your answers to this week's questions in the comments of this week's LinkedIn post.

Bill Gates says robots will take construction jobs by 2030. Dustin DeVan offered to bet his entire net worth against it.In this episode of Bricks, Bucks & Bytes, Owen, Dustin and Martin pull apart the 6,000 word essay Gates published this week and ask the question nobody in construction wants to answer out loud: if AI is making everyone so much more productive, why has nobody's headcount actually gone down?

Four founders competing in construction layout walked into the same room.Nobody expected them to agree on much.But across the conversation, all four revealed the same thing about who they are really up against.Not each other.Tessa Lau, CEO and co-founder of Dusty Robotics: “Pretty much our biggest competitor is chalk lines and measuring tape.”William St-Pierre, CEO of Mechasys: “Our biggest competitor today is like DeWalt or Milwaukee with their tape measures.”Tomer Elran, co-founder of LIGHTYX: “They are not transferring from one technology to the other. They’re transforming from almost zero technology.”Derrick Morse, founder and CEO of Rugged Robotics, on HP entering the category: “HP has a marketing machine and a budget that I can only dream of. So for them to enter the race and to participate, I think is a net net win for everyone.”Eight rounds. Sixty-second answer caps. No slides.They debated accuracy, distribution, union adoption, capital, robots versus laser projection and whether construction layout could become a winner-take-all market.It took us more than eight months to get these four founders into the same room.Huge thanks to Christian Reed, founder and CEO of REEKON Tools, for moderating and to Tessa, Derrick, William and Tomer for taking part.#bricksandbytes #construction #constructiontech #constructionrobotics #aec**Chapters**00:00 Intro01:00 Why Construction Layout Is Ready for Automation02:51 Meet the Four Founders Competing for the Floor05:44 Chalk Lines, Tape Measures and 5,000 Years of Habit08:50 Debris, Dust and the Mess Nobody Plans For11:37 The $18M Hospital That Reportedly Saved $2.5M14:49 HP Entered the Market.

“We never use the word AI anywhere. You’re saying we’re an AI company, not me.”Mo Akbari-Hochberg built HoloBuilder and sold it to FARO. Now he is back with BuildCrew, a preconstruction platform backed by Khosla Ventures that uses digital workers to help contractors with estimating, trade scoping, bid levelling and preconstruction RFIs.In this episode, Mo explains why he believes 99% of construction AI teams do not properly understand the technology they are building with, why access to the same AI models does not produce the same results and what contractors should look for when buying AI software.We also discuss how BuildCrew can produce a rough order of magnitude estimate in 4 to 5 hours, compare 10 electrical bids in around 20 minutes and identify gaps across construction drawings and project documents.🎥 Link in comments.#BricksAndBytes #ConstructionAI #ConstructionTechnology #Preconstruction #ConstructionEstimatingOur Sponsors:BreadCrumb- 50,000+ projects globally.

This week's briefing covers three things that landed in the same week and all point at the same question. Where is the work going next.In the last five weeks more than two billion dollars has been poured into construction machines that drive themselves. TerraFirma raised 115 million. Travis Kalanick, the man who founded Uber, raised 1.7 billion for Atoms, which includes an autonomous mining division. Komatsu signed a partnership to put autonomous bulldozers and excavators on American jobsites. And Bedrock Robotics, who regular listeners will remember from our Texas site visit, announced fully autonomous excavators working on live customer sites in Nevada and Texas. But this is not one market. There are five distinct business models in play, and they do not all sit on your side of the table. One of them is bidding against you for the same earthworks contracts.Then the reason all this money is chasing machines in the dirt. Travis Kalanick put it simply. Manufacturing changes atoms, real estate stores them, transport moves them. Uber was the network layer for moving things. His new company is building the same thing for entire industries. Construction sites may be where AI learns to understand the physical world, and every hour an autonomous machine works it is banking data that no lab can buy off a shelf.Then the two numbers that matter for your order book. American housebuilders dropped 12.4% in July to their weakest level since November 2022. The strange part is that permits went up 5% to 1.44 million. Builders are paying for permission and refusing to break ground. That is them telling you in the clearest language they speak that they do not trust demand at today's prices. And the work that has been filling the gap, data centres, hit a new kind of wall this week. Not money. Not power. Votes. Fort Worth voted unanimously to pause new data centre construction. Louisville voted 24 to 1 to pause approvals for six months. New York already has a statewide freeze in place. Permission has become the scarce input, and it is being decided city by city.Drop your answers to this week's questions in the comments of this week's LinkedIn post.

We spoke to Kevin Peterson this week. He runs the tech at Bedrock Robotics.He told us their control room "looks like StarCraft, actually."You click on an excavator on a screen and give it a job. Then it just digs. Nobody sitting in it.This went live on real customer sites on Monday.The same day, a company called Gravis Robotics got $200 million from SoftBank.We asked Kevin about the timing. Nobody seems to know.Full chat with Kevin and Alain is out now on Bricks Bucks and Bytes.#bricksbucksandbytes #bricksandbytes #aec #constructiontech #aiOur Sponsors:BreadCrumb- 50,000+ projects globally.
