Quality Control

Next Steps in Revolutionizing the Industry with SBCA’s In-plant Digital QC Program

SBCA is involved with “In-plant Quality Control” programs to fulfill its mission of members gaining the knowledge and power to run successful, growing, profitable companies offering a compelling competitive advantage in the marketplace for their customers and professional growth for employees.

Implementing SBCA’s Vision for Digital QC & 3rd Party Digital QA

Popstar Lady Gaga was once quoted, “I’m just trying to change the world, one sequin at a time.” This idea of incremental change in an attempt to make a great change embodies the work that has been done recently in the development of SBCA’s Digital QC and 3rd Party Digital QA programs.

In the SBCA booth at BCMC 2018, SBCA staff member Joe Schauer displayed how the SBCA Quality Control (QC) Committee’s initiative is a giant step forward in the area of component manufacturing QC.

Break the Blame Cycle

Quality control (QC) is often thought of as an effort to catch mistakes made by production. However, many times problems and solutions extend beyond just the manufacturing process.

Testing is underway to determine the effects of weather exposure and time on trusses.

Lumber Design Values

No matter the species, component manufacturers (CMs) purchase and rely on the accuracy and reliability of many different lumber design properties, including: bending (Fb); shear parallel to grain (Fv), compression perpendicular to grain (Fc^), compression parallel to grain (Fc), tension parallel to grain (Ft), and modulus of elasticity (E and Emin).

Allowable Variances In Trusses

Question: 

My framers are always complaining that the “trusses are bad.” I am looking for tolerance information that not only addresses the allowable variance in length and height, but also allowable variation in the top chord with regard to straightness (i.e. how straight should a pull string line from the top and bottom of top chord be?). Also, if trusses are set on a perfectly level wall, what variation is allowed from truss to truss (i.e. if I put a 10 ft. straight edge perpendicular to the trusses, how much can they vary in height, not just at peak or bottom but all along the top chord)?
