Founded in 1996 by David in Nevada City, California, Zachry Engineering began with experience in high-rise pre-cast panel design before transitioning to residential and commercial structural work in the Lake Tahoe-Truckee region in 1999. A pivotal shift occurred in 2009 when the firm adopted three-dimensional modeling using SketchUp and AutoCAD Civil 3D, revolutionizing its design process. This move enabled the creation of full structural models directly from architectural designs, improving accuracy and efficiency. The firm has since become a recognized leader in SketchUp-based design, presenting at SketchUp Basecamp in 2016 and 2018. With thousands of structural details in its digital library, Zachry Engineering leverages advanced software to identify and resolve potential construction issues before they arise on-site.
