Can quality be determined by examining the environment of the facility manufacturing the product? It seems like the two are unrelated, but, after evaluating hundreds of facilities, quality seems to be proportional to the environment of the manufacturing. By this, I’m not saying that brand...

On a recent Quality Assurance Audit at a large facility, we witnessed a floor truss builder carefully spacing out his floor truss webs in the allotted space available with precision and care. He was very meticulous. I asked him why he was doing that and he explained that his in-house inspector...

Once in a while, I’m asked—Is there ever an occasion when connectors on both sides of the truss need exact placement? Well, the answer might surprise you. There are, in fact, several situations where the top face connector and the bottom face connector need to be exactly...

The requirement is: an inspector will, on average, inspect one critical plate for every inspection made during a week. That requirement is the baseline number for the quantity of critical inspections to perform—but because some trusses do not have critical plates, it’s necessary to...

In the November 2017 article, “So Who Exactly is Responsible for Lumber Quality?”, we discuss the abundance of quality building materials and the responsibility of the fabricator to evaluate their application in products. We should recall the ultimate decision maker in determining...

A critical plate is a plate with a Joint Stress Index of 80% or greater. The ANSI/TPI 1–2014 Standard stipulates that critical plate inspections must be conducted when completing the three inspections per station/per shift/per week requirement. On average, the standard requires one...

When a 3rd party inspector inspects a licensed plant, what exactly are the auditors looking for? And what can the fabricator get from the experience? What the inspection is NOT, and why that matters: The part 1 audit of the in-house paperwork is not a grade on neatness. It’s an...

After recently upgrading to a newer vehicle, I have been amazed at the new safety features. While it’s not self-driving, the features are definitely approaching an autonomous car. The basic functions are things like active cruise control with the “stop&go” function, which...

Per ANSI/TPI 1–2014, National Design Standard for Metal Plate Connected Wood Truss Construction, plates should be installed within a 10 degree tolerance. So what happens when the plate is rotated and exceeds this requirement? The simple answer is: the configuration and design of...

Roof and floor trusses are important components that need special consideration to insure their correct manufacture. Components built to the IRC and IBC require the manufacturer to adhere to specific requirements. These requirements provide a blueprint to facilitate the manufacturing of a...
