St. Helena, CA
Duckhorn Vineyards
Scope/Solutions
Duckhorn Vineyards, founded in 1976, is located on a ten-acre parcel on the Silverado Trail north of St. Helena. Several families share in the ownership, including the Duckhorns, who are responsible for management of the winery. SGH provided structural engineering design services for a new wood-framed, two-story building on the property.
The building, with Cape Cod characteristics, houses the vineyard’s administrative offices and wine tasting facility. The tasting room features heavy timber trusses and a wrap-around veranda. Highlights of SGH’s design for this project include the following:
- Designed the mat foundation and building structure, which is located in a flood plain, in accordance with residential floodproofing requirements of the Federal Emergency Management Agency
- Designed the wood-framed structure, including scissor trusses at the tasting room roof
- Monitored the work during construction

Additional Projects
West
1275 Market Street
Constructed in 1977, 1275 Market Street experienced water intrusion of varying severity and required repairs. State Fund hired SGH to investigate, repair, and manage the facade rehabilitation for the seventeen-story structure clad in granite panels.
West
One California Street
SGH performed a condition assessment of the precast panels and found corroding reinforcing was causing the concrete panels to crack and spall. We subsequently developed a facade rehabilitation program using a custom designed mortar to match the existing concrete.
