Home Building Technology, Part XV: The Rebirth of Wood Joe Kannapell, PE Wood was not held in high regard in the truss drafting department where I began working. Our fabricator customers often wanted their trusses designed with “old lumber,” meaning the obsolete size of 1-5/8” x 3-5/8”, even though the 1.5” x 3.5” size had been in...

The Last Word: Truss Math on Your Phone Joe Kannapell, PE Few, if any, pieces of wood will pass the scrutiny of an 8’ level, and the superintendent of Bill Milburn’s homes in Texas wielded his level like a weapon. When I walked those houses, I needed a level, plumb line, string line, and more. Today, I have some of the same capabilities in... Read More March 2026 Issue #18320 Page 192
Home Building Technology, Part XIV: Truss Equipment Proliferates – Assembly Joe Kannapell, PE You could say that Carol Sanford flipped the script on machinery, like he had in so many circumstances throughout his career. In the 1950s, when he couldn’t sell his modular homes in Ohio, he shipped them to Florida. When he couldn’t sell them there, he turned to selling site-built...

Recognizing the Value of BuyMetrics Valerie Hansen When I was notified we’d been selected by Construction Tech Review as the Cloud-Based Lumber Purchasing Platform of the Year 2026, I was very surprised, and I hadn’t even known we were nominated. But, as I thought about this news, I realized how grateful I am for the trust and... Read More February 2026 Issue #18319 Page 91
The Last Word: Bill McAlpine’s Legacy Joe Kannapell, PE The name “Bill McAlpine” has such resonance in the component industry that when ITW acquired the company and removed his name, they soon found value in returning to the Alpine moniker. There are many reasons McAlpine earned that singular honor, but one of the least recognized is... Read More February 2026 Issue #18319 Page 190
Home Building Technology, Part XIII: Truss Equipment Proliferates – Component Saws Joe Kannapell, PE As housing demand accelerated in the 1960s, builders increasingly turned to trusses. But, lacking better equipment, truss shops had trouble scaling up to fill their orders. Early shops had little more than radial arm saws to cut members and wood tables to assemble them. They had exhausted every... Read More January 2026 Issue #18318 Page 10
Design Connections: AI in Truss Design: Opportunity or Long-Term Risk? Geordie Secord Artificial Intelligence (AI) is no longer a distant concept—it’s here, and it’s reshaping industries at an unprecedented pace. For component manufacturers, AI promises efficiency, speed, and cost savings. For years now, we’ve been promised that one day we would be able to... Read More January 2026 Issue #18318 Page 118
The Last Word: (When) Will AI Overtake the Truss Industry? Joe Kannapell, PE Artificial intelligence (AI) has been 70 years in the making since eminent AI pioneer, John McCarthy, coined that term in 1955 to describe “the capability of a machine to imitate intelligent human behavior.” Truss software has been 50 years in the making, with scant penetration of AI...

Home Building Technology, Part XII: Plate People Proliferate Joe Kannapell, PE A great American competitive struggle broke out in truss shops around Miami in 1957. The owners of these shops learned that two new plates had hit the market, and both worked without supplementary nailing. The Sanford Grip-Plate that they were using required hundreds of nails to be hammered into... Read More December 2025 Issue #17317 Page 10
What If Innovation Isn’t Just About Technology? John Holland Innovation begins with a question: “What If.” What if lumber became stronger when arranged in triangles and joined with steel plates? What if geometry could live inside a computer instead of on paper? What if building trusses offsite proved better than framing rafters onsite? Every... Read More December 2025 Issue #17317 Page 76
