Driving down Sonora's Tuolumne Road, after passing normal earthtone retail and industrial buildings scattered in the landscape, one isn't expecting the dramatic change looming ahead. As one rounds the curve at Nugget Boulevard, you are suddenly looking straight onto the dramatic, deep green buildings of the Tuolumne Utilities District (TUD) Centralized Office Facility.

Positioned to create a landmark setting, TUD has established it's headquarters complex on the corner of Tuolumne Road and Nugget Boulevard, in Sonora, Calif., on what was formerly a truck staging area for the old Pickering Lumber Company (now the Standard Lumber Mill site, Sierra Pacific Industries). The new Centralized Office Facility brings together TUD's administration, warehousing, operations, vehicle maintenance facilities and personnel in a consolidated complex.

Consisting of four buildings, grouped around a central commons area, the complex is designed to allow operational flexibility for the district, as well as friendly access for the public, and is master planned for future growth and expansion on the eight acre site. The four buildings are all pre-engineered metal buildings, utilized to take advantage of the industry's clearspan capabilities, economics and efficiencies of construction, and design innovations, as especially expressed in the administration building.

The administration building adopts the County's agricultural building forms of gables and shed extensions to create an eye-catching frontispiece to the complex, facing directly onto the public roadways. The warehouse, operations building, and vehicle maintenance buildings maintain more "traditional" rectangular forms; however, this 
is used as a starting point for the overall design of the complex.

The four buildings are cloaked in a uniform deep green skin of metal siding and metal roofing. The siting of the buildings around the commons area, proportioned to the building mass and volume, and the texture and pattern of the building skin, all of which is afforded by the metal building system, provides a unique backdrop to the functional operations of the District. The deep green of the building masses is then highlighted by the use of deep primary colors of blue, yellow, and red; the blue is used at larger elements of exposed structure, overhead doors, and awnings, to counter the overall green building mass, while the yellow highlights circulation and safety elements, and the red is used for trim and accents. The administration building exterior skin is a combination of metal siding and plaster, highlighting the public functions of the building.

The interiors of the buildings are given the same amount of design consideration as the exterior. The pre-engineered metal building systems allows for a free flow of interior spaces and creates the need for an organization of the interior finish and color schemes. Interior colors continue the hues of native colors, and are interwoven with patterns in the carpet and tile. Interior colors have a presence, but are more subdued, to allow for a pleasant working environment. Casework incorporates accent coloring, and custom signage emphasizes the district's logo.
