As a general rule, when you cut lumber to length, the lumber grade is unchanged. In those cases, care should be taken to transfer that grade verification along with the cut lumber. This can be done with a lumber crayon, segregation, tagging, or many other suitable ways. Ripping lumber,...

Being that it is early spring, it may be a good time to think about taking steps to protect your family in the event of a tornado. The 4th Edition of FEMA P-320, introduced below, contains a “treasure” of design information for constructing a residential safe room, either in the home...

The future is here. It is common knowledge that wood is a renewable and environmentally friendly building material. There are two types of wood-framing methods in North America. The most common method for residential construction is light-frame construction using either balloon-framing or...

Not one of the fathers of our industry did more design work than Vivian Hollinshed. Over his 55 active years, on the small drafting board behind his desk, this magnificent man named Vivian crafted countless fine homes and innovative commercial buildings. All the while pioneering trusses in a...

“If I didn’t care for him so much, I’d let him go,” said the late Vivian Hollinshed about an aspiring young designer, Chuck Rogers. Chuck knew nothing about trusses when he came to Vivian’s company, Comtech in Fayetteville, NC. And now, nearly 20 years later, thanks...

I worked closely with Siboney Diaz-Sanchez with Overland Partners Architects to be sure that our truss designs would meet...

Unlike solid-sawn lumber, the mechanical properties of some materials are greatly affected by ambient temperatures and solar-radiation heating, as depicted by the photograph. However, while the engineering design properties of solid-sawn lumber are not affected by ambient temperatures, they can...

What once was frowned upon has now become very common. Off-site designing and off-site sales individuals or teams can be a very good way to expand your company’s capabilities. The biggest driver of its emerging acceptability is the fact that the pool of talent is larger when looking...
