Many years ago, early in my career as a truss designer, I was interrupted by the production manager. He loudly entered my office with a piece of 2 x 12 and a circular saw and abruptly slammed both on top of my drafting table that was sporting a newly created truss layout. (We did not have...

Recently, when a building owner started getting leaks in the roof and noticed unusual variations in the ceiling, I was asked to do an inspection to determine the best way to correct a deflection problem. Upon inspection, it was very evident that the roof trusses had not been installed correctly...

Recently, while conducting an ANSI/TPI audit, a splice caught my eye. When I investigated further, I realized that the bottom chord of the truss I was investigating had a very short, 2” chord segment. I immediately assumed the truss builders had cut a short block to make up for a miss-cut...

Years ago, truss design was focused on a simple calculation that determined the final forces that would be considered to be imparted on a truss component. These simple forces were used to determine the design. Things like snow, wind, and building materials weights were generally the only...

Quality, productivity, and speed are intertwined and impact each other. My previous article, Where is Your Focus on Manufacturing?, emphasizes that improving quality starts with implementation of the ANSI/TPI 1 standard—and, with that process, you will improve proficiency and speed. The...

Recently after receiving a phone call from a client, I reflected on our conversation. I was a little caught off guard with the direction the conversation took and felt like I needed to make a few issues clear. And, it has led me to reflect on boundaries and guidelines – why they exist and...

Sometimes it is necessary to deviate from the truss design drawing and use a different connector. This may happen when a specific size connector is not available or when the original connector has been removed. Per ANSI/TPI 1 Section 3.6.3, a metal connector can be substituted if the new...

When completing an in-house inspection, a critical plate inspection is required for each truss inspected. This requirement is from ANSI/TPI 1–2014. Specifically, per section 3.7.1: No less than one critical joint per Truss selected for inspection, on average across all operational...

Face the facts—occasionally, it is necessary to replace connectors. It’s part of the manufacturing process. In my May 2016 article, Is There a Reduction For Plating in a Previously Plated Area?, we discuss the limitations and considerations of removing a plate, including upsizing the...

On occasion, we are required to utilize a detailed tooth count to qualify a connection on a metal plate connected wood truss. Fortunately, we have several tools that can assist us. My June article, “Which is Better: Plate Placement Method or Tooth Count Method?”, includes a...
