Forming the Future of Construction: Concrete Forms
IntroductionToday we welcome Joe Purtle, who is here to talk to us about concrete forms. Joe has been in construction for well over two decades, and he’s currently the COO of Doka, which specializes in forming and shoring. Eddie shares a bit about his experience in construction back in the 2x4 and plywood days. He shares how cool it’s been to see the complexity of forms increase over time and to see how those forms have become woven into BIM software.We discuss how designers and other stakeholders view concrete forms. Joe explains that the placement of concrete drives the schedule on many large projects. And the placement of concrete is largely dependent on the completion of formwork. Cycling of formwork and big dadgum messesEddie asks Joe to explain the cycling (reuse) of forms on large projects. Doka’s job is to understand the complicated aspects of forming and pouring and how these complexities can affect a schedule. We discuss the benefits of modular approaches and cycling of forms. Joe discusses the importance of knowledgeable planning and the unfortunate results when things to wrong and a form gets trapped. It’s what the bros and their Georgia buddies would call a “dadgum mess.”Joe shares about how he has seen companies process decisions related to renting vs. buying. He also discusses sustainability issues and equipment that measures temperature and pressure to optimize the curing process. We get into the optimization of pouring and the incorporation of reusable sensors that give designers and project managers the ability to know things they would have previously not known without expensive, messy tests. Prefab of formworkEddie asks Joe to share about prefab work such as cast-in-place parking garages. Joe explains that Doka can build and ship complete beam forms that are pretty much ready to plug and play when they arrive at the job site. They have CNC machines that can put curves into forms with highly detailed specs when the customer wants it. Tyler connects these abilities to the overall increase in complexity of structures. Joe shares about the pride we’ve discussed in previous episodes that comes with seeing a really cool building and being able to say you had something to do with that. BIM ModelingEddie asks Joe to explain how Doka’s work integrates with the BIM process. He explains that they’re already working within Revit and Tekla but that they are quickly extending their integration even further. We discuss how AI is streamline design. Then there are the AI features that simply increase the team’s everyday operations. Joe shares some thoughts about “real BIM” vs. “Hollywood BIM” and how these differences affect scheduling. Eddie shares some thoughts from a designer’s perspective as well as thoughts about storing huge form components that are not easy to move. We spend some time discussing the design rules being used to form AI and how significantly this process will likely change design work in the future. Then we discuss the role that human insight and finesse play in this process. Megaphone Message Joe’s message to the industry is this: The industry needs to come together and stop working in silos. The sooner we can create true collaboration through the available technologies, the sooner we’ll progress to a future we can’t even imagine at this point.

Bracket Mayhem - Picking the Hardest Construction Job
00:00 - Ennui and another TylerWe know that you come here for philosophical insight and existential explanations, so today we’re discussion ennui. Tyler shares… tries to share about this state of listlss… listsles… listlessness and dissatisfaction.After this fun, we welcome our new vocal presence, Tyler Cook. Tyler shares about the secret to connecting with Zoomers. It’s all about tier lists and brackets. So today we’re going to do a tourney bracket.05:23 - The bracketToday we’re exploring niches. We don’t want to share any spoilers here in the notes, but here are some opinions that are shared as we process this competition. Concrete is tough.Drywall corners are hard.Flooring is not comfortable work.Spending your day staring upward will do a number on your neck.We don’t want to fall off a roof.Dooky’s not fun.OSHA keeps telling us not to touch a live wire.Demolition is fun for 30 minutes.Eddie is confident that he’s done with roofing.Welding sometimes happens in really dangerous places.If you're interested in jumping straight to some specific first-round debates:6:06 - Carpentry vs. masonry7:40 - Drywall vs. concrete 10:20 - Ceiling vs. flooring16:01 - Roofing vs. HVAC23:37 - Landscaping vs. painting24:48 - Electrical vs. excavation 30:44 - Glass installation vs. demolition33:21 - Semifinals39:15 - FinalsThe takeaway from this process? Man, tradespeople do some tough stuff.

Arthur Powell Davis Said Dam It, So They Did
If you're interested in learning more about the construction of Hoover Dam, scroll to the end of the show notes for links.00:00 - A Quick Dam Joke, the Consortium, and Some StatsWe question our ability to keep our puns in check. Sorry, Mom.Then we move on to the contractors. We discuss the consortium called Six Companies Inc. that won the bid at nearly $49 million, approximately $860 million in today’s dollars.Eddie makes a conveniently timed comparison to the Washington Monument. The Hoover Dam is 726 feet tall–almost 200 feet taller than the Washington Monument. Only 6 buildings in the US were taller than the dam when it was built.We discuss some stats:-4.4 million cubic yards of concrete were used in the project. That is enough to pave a two-lane road from Seattle to Miami or a four-foot-wide sidewalk around the Earth at the Equator or enough to pave a two-lane road from Seattle to Miami.-Its base is as thick as the length of 2 football end-to-end-It has 4 intake towers (30’ diameter each) that can carry enough water to fill 900 bathtubs in only one second. That means 1,448,100 “bathtubfuls” of water will have passed through the dam in the time it takes you to listen to this episode.07:15 - Construction Costs and Power OutputTyler mentions that the cost of the initial construction, which finished in 1936, wasn't paid off until 1987. Eddie discusses the way that we handle financing for capital projects, spending not just tomorrow’s money–but money that won’t come in for decades.We compare these expenses to the absolutely monumental amount of economic impact that the electricity from the dam has had. Here’s where the 4 billion kilowatt-hours each year goes:19% to Arizona23% to Nevada58% percent goes to California (15% to LA, which is 270 miles away)10:46 - Hoovervilles and FatalitiesEddie fills the gaps in Tyler’s history education with an explanation of the Hoovervilles from the Great Depression. Hoover didn’t get much positive PR aside from this dam.We discuss the desperation of the Great Depression is shown by the fact that the ability to line up workers for a job to do this. Tyler shares the troubling coincidence is the fact that the first and last men to die on this project were father and son.Thinking about these human costs leads us into a discussion about the structure of incentives and penalties that drove the owners of Six Companies to push the pace of construction.19:53 - Takeaways: Big Projects, Green Energy, Old-school DraftingWe discuss the fact that bold projects lead to emboldened people who move on to even bolder projects. Sometimes biting off more than you can chew leads to growth.Tyler makes the point that this dam was a green-energy project long before the term “green energy” was coined. He also expresses awe at the thought that all of the drafting for this massive project would have been done by hand.Eddie stops short of calling himself a history buff, but he expresses a deep respect for the teams of designers and workers who accomplished massive projects like this with so little help from what we consider advanced technologies.Tyler invites you to submit your ideas for future research-based projects.If you’re interested in additional details about the Hoover Dam, explore these sources:EIA.govUSBR.govB1M video: compares the world’s largest dams to other structuresLake Mead historical water-level chartNPS.govBechtel’s page about construction of the damOld publicity/education videoLibrary of Congress PhotosVideo of the physics and engineering involvedCheck out the partners that make our show possible.Find Us Online: BrosPodcast.com - LinkedIn - Youtube - Instagram - Facebook - TikTok - Eddie's LinkedIn - Tyler's LinkedInIf you enjoy the podcast, please rate us on Apple Podcasts, Spotify, or wherever you listen to us!
