Last year LP invested $45 million in Entekra, one of the nation’s leading off-site homebuilders. As this type of construction gains popularity in the U.S., a number of architectural firms have asked Entekra to do presentations about how to successfully design for off-site homebuilding.
“What we really stress to them is the importance of advance planning,” says Entekra CEO Gerry McCaughey. “In Europe, it’s common for architects to provide all the details in advance. But in the U.S., it’s a different story. Entekra often gets architectural drawings where some of the details say ‘to be verified in the field.’ But we need to create a 3-D model of the house before it’s even built, so architects can’t omit details like the window dimensions.”
As the industry continues to grapple with limited staff, smarter building solutions and simplified building methods are a way to help speed things along. One of the major benefits of off-site homebuilding is construction speed. But when key architectural and engineering details are missing, Entekra has to spend six to eight weeks trying to track down the information and get the drawings completely ready. “That really elongates the building process unnecessarily,” says McCaughey.
Architects and specifiers also need to know that some building products are ideally suited to off-site manufacturing. “We use a lot of LSL, and that’s a material that’s under-used in the U.S. in our opinion,” adds McCaughey. “It solves a lot of the problems that builders have with lumber, especially in the upper end of the market. We’ve also found that fire-rated OSB also works very well, particularly for multi-story buildings.”
“Architects and builders are starting to realize that a lot of what’s broken in this industry is due to lack of forward planning and information-sharing,” says McCaughey. “We can’t get drawings that say ‘field verify’ anymore. Architects need to remember that off-site facilities are building homes with high-precision automated equipment – and we can’t do our work if the details are missing.”
At LP, we understand the challenging dynamics of the building industry—deadlines, limited skilled workforces, potential liabilities, reputation management and inventory shortages, just to name a few—and how those are amplified during this time of unparalleled unknown amid COVID-19.Continue Reading
While LP® FlameBlock® Fire-Rated Sheathing offers both flame-spread and burn-through resistance, it’s important to remember these are different concepts as they relate to construction and the code. Flame spread is the propagation of flame across the surface of a material and can be minimized with “fire retardants” that delay ignition. Burn through is the penetration of flame through an assembly and is countered by the “fire resistance” of the assembly. And then there is the notion of “fireproof” materials. As a refresher, let’s ask a few experts the definition of each term.
In the building business, in-person communication has always been a vital component in talking to potential clients in a personable, efficient way. With social distancing disrupting common business practices, like in-person meetings, building professionals have had to pivot plans to adjust to the current landscape while maintaining a steady stream of business.
