Office & Mixed-Use

McManis Family Vineyards, Ripon, Calif.

mcmanis_vineyardsCompleted in December 2010, the 4,400-squarefoot, single-story corporate office building is built with rich, warm materials. Serving as the centerpiece and visual anchor of the winery property, the architecturally distinct facility is designed to support both administration and farming operations. Additionally, the building has a separate delivery entrance located adjacent to the truck scale to accommodate check-in and weighing functions, along with restroom facilities for the drivers. Enhanced with large wood entry doors, the corporate office entrance features an upswept roof, stone columns and stamped concrete.

When the McManis family decided they needed a new corporate office, they turned to general contractor Roland Construction Inc., whom they have worked with for more than 12 years. "Besides the corporate offices, Roland has built seven other structures at this facility, including two press/crush roof structures, one filtration roof structure, three barrel and case good storage warehouses, and a maintenance/storage building," says Jim Hoagland, president of Roland Construction. "Off-site, Roland has worked on two agricultural shop buildings that support the vineyard operation.

For the project, Roland Construction utilized a pre-engineered metal building system from Varco Pruden Buildings, and metal wall panels from Kingspan Insulated Panels Inc. The building features 6,400 square feet of AP- 900 4-inch-thick (R-32) urethane foamed panel with a 26-guage Energy Star-rated embossed Evergreen Valspar Fluropon PVDF exterior finish; 2,500 square feet of AP-300A 2-inch-thick (R-16) urethane foamed panel with a 24-gauge Azteco embossed Surrey Beige Valspar Fluropon PVDF finish; and 2,200 square feet of AP-200 2-inch-thick (R-16) urethane foamed panels with a 24-gauge embossed Surrey Beige Valspar Fluropon PVDF finish.

The steel columns of the building structure are outboard and wrapped in stone veneer, allowing for metal stud shear walls and clean lines inside. At the skylights, the rafters are wrapped with wood. The triple-glazed fixed skylights are Model 800IB from Sunoptics Skylights. The roof is 4-inch-thick (R-32) 900 Series insulated panels with an Energy Star-rated Green color. Exterior walls are Hardietextured siding with 2-inch-thick (R-18) 200 Series insulated wall panels above.

"The building is the public face of the winery, and the message that the owners wanted the building to express was a functional, non-ostentatious, environmentally responsible project," says the designer, Larry Wenell of WMB Architects.
