Joseph Phelps Vineyards Building Renovation & Seismic RetrofitAug 05 2015 · 0 comments · NISHKIAN MONKS, Renovation, Seismic ·0
After an extensive 16-month renovation and seismic retrofit the Joseph Phelps Vineyards Guest Center re-opened its original winery building to visitors this summer. Originally designed by renowned architect John Marsh Davis in 1973 the majority of the historic building’s interior was removed, an interior floor was added, and the old building seismically upgraded. The Phelps family and the executive team collaborated with Baldauf Catton Van Eckartsberg (BCV Architects), Brandenburger Associates AIA, Cello & Maudro Construction Company (General Contractor), and Nishkian Monks to repurpose the interior winery spaces, enhancing the guest experience, while maintaining the building’s existing redwood exterior design.
Timing and logistics were key challenges as work occurred with hundreds of guests visiting the winery campus located in California’s Napa Valley. The architects focused on creating lighter spaces and installing modern utilities, while preserving the classic character of the structure. One of the primary challenges of the project was the seismic reinforcement and safety of the 40 year old structure.
The structural scope of this project involved converting an existing 6,000 square foot (~560 square meters) one-story wood framed wine production building into a two-story mixed use facility; with the first story re-purposed as a guest receiving and hospitality area, and the second floor as office space for winery staff. All of this work was done while preserving the original shell of the building to the fullest extent. Existing interior columns supporting the main ridge beam were removed and replaced with architecturally expressed glulaminated wood trusses to create an open office floor. Two timber framed floor trusses were constructed each side of the gallery and were designed to mimic the original redwood entry trellis. As part of the winery remodel, the seismic system for the building was upgraded to meet current building code. Fortunately the seismic upgrade to the winery was mostly completed when the 6.0 Napa earthquake struck in August 2014, and the under-construction winery was not damaged by the quake.
In addition to providing structural design of the winery remodel, Nishkian Monks also provided structural design of walkways and decks of the temporary wine tasting facilities during construction; and design of temporary shoring means in the winery for the General Contractor.
The project’s success is due to the strong coordination efforts of the design team and the leadership of Joseph Phelps Vineyards. “At every step of the renovation planning, it was very important to my father and the rest of our family to preserve the original John Marsh Davis design,” stated Bill Phelps, President of Joseph Phelps Vineyards. “We are very pleased with the design team’s efforts to maintain the building’s historical aspect.”
