Organizations / ZFA Structural Engineers

Gregory Zucco started Zucco Associates in 1974 in Santa Rosa, California. His company has built an extensive, cross-disciplinary project portfolio, focusing on wineries, educational facilities, and public and civic structures. He was later joined by Dennis Fagent in 1993 and became Zucco Fagent Associates. Over the years the company opened offices in San Francisco, Sacramento, Silicon Valley, and, most recently, Napa in 2014 following the Napa Earthquake. In 2001, the company changed its name to ZFA Structural Engineers.

In the 40+ years since its founding, ZFA has provided their expertise to historic renovations, seismic evaluations and retrofits, education facilities, civic structures, commercial buildings, hospitality structures, wineries, healthcare and senior living facilities, multi-family and custom single-family residences, large-scale art sculptures, and more.

Notable ZFA projects in Northern California include the Castello di Amorosa winery in Calistoga, the adaptive reuse of an 1864 brick Naval structure for Savage & Cooke distillery at Mare Island, Dominus Estate Winery in Yountville, renovations at the Pebble Beach Resort in Pebble Beach, restoration of the 1950 San Mateo High School Performing Arts Center, College of Marin’s New Academic Center, a five-story new office building on bay mud at 85 Bluxome Street in San Francisco, the American AgCredit headquarters in Santa Rosa, and the Visa building in Palo Alto, which was the first use of eccentric buckling-restrained braced frames (BRBF-E) in a building. ZFA has also engineered hundreds of high-end custom homes all over Northern California, often utilizing advanced engineering techniques and systems such as performance-based design, steel plate shear walls, and damper frames. One of ZFA’s custom residential projects in Berkeley, the Ranger House, was featured in the New York Times in March 2019
