Semler: Offsite construction is still in its infancy. Offsite will evolve allowing increased efficiency and speed in homebuilding. For every six construction workers who leave the industry, only one enters. With this type of labor shortage, offsite will be the way homes are built in the future. We just won’t have the labor force to do it any other way. Sielaff: There is power in technology in the offsite construction mar- ket. With 3D BIM modeling, clash detection, automation in machinery, and how computer numeric control (CNC) machines are talking to the modeling software, it’s taken what the industry can do to an entirely new level — the precision is remarkable. Whether you’re building with modular, log, timber-frame, SIPS (Panelized), or concrete panelized construction, all industries are utilizing software in today’s world in fabrication, take-offs, and manufacturing. We’re in a new platform of diagnostics with what can be shown, engineered, and designed on the computer and then transposed into the machinery cutting or fabricating the final element.
struction timeline without “days-off” due to inclement weather. Using employees for specific tasks and optimizing productivity is another key benefit of offsite construction. The ability to purchase materials in bulk and deliver to the same location is even more important in today’s marketplace of supply-chain disruptions and transportation issues. Armstrong: SIP Design’s Best Practices Series is a valuable resource available free of charge. The simple concept of speed of construction (SoC) is interconnected to every other factor contributing to builder and jobsite logistics. Builders, architects, and owners are focused on the bot- tom line. SoC is one way SIPs conserve project funds while surpassing the IECC 2021 building codes and energy performance standards. As an example, a recent Gig Harbor, Washington residence is a testimony to SIP SoC, reporting just five days to install the entire project (SIP walls and roof). The builder specifically cited savings in labor, fewer trade involvement, and, of course, expected energy savings.
