John Adams Academy

Challenge Accepted

CJA is proud to be part of the team behind this exciting project in El Dorado Hills—a new 62,000 sq. ft. charter school for the John Adams Academy campus serving grades K–12. The school was created through the adaptive reuse of an existing two-story office building located within the El Dorado Hills Business Park. 

The project includes 34 classrooms, featuring dedicated Art, Drama, and Choir rooms, as well as a Library. A standout element of the design is the innovative incorporation of a full-size gymnasium and multi-purpose room with a high school regulation basketball and volleyball court, along with a performing arts stage and bleacher seating—all accommodated within the existing office building structure. Integrating a full-size gym into a two-story office building presented a unique challenge and required a highly creative design solution.

Additional program elements include a Science Lab, Lunchroom, Administrative Offices, Nurse’s Station, Teacher Lounge, breakout rooms, and supporting auxiliary spaces.

Annunciation Greek Orthodox Church

A Modern Facility for an Ancient Faith

For over 60 years, Greek Orthodox Christians have worshipped and celebrated their culture at facilities located at the Annunciation campus at 600 Alhambra Boulevard in Sacramento. Founded by a handful of immigrant families from Greece, the Annunciation Greek Orthodox Church has become a thriving Parish of over 500 families.  To meet cultural and ministry needs, a new Family and Education Center was commissioned to replace aging infrastructure and facilities – and build for the future.

CJA interfaced with a number of groups during the master plan process, including a small executive building committee, a larger full building committee, the parish at large and three separate neighborhood community organizations. The main drive for this master plan was to lay out the facilities so that new buildings could be constructed while still occupying the existing buildings and the existing buildings demolished after occupancy of the new buildings. This was especially challenging given a tight 2.2 acre site. New replacement facilities include:

• a multi-purpose parish hall,

• bookstore,

• classrooms,

• library,

• meeting rooms,

• preschool,

• administrative offices,

• a larger parking lot and

• an extensive courtyard.

Organized around the campus courtyard, called the Plateia in Greek, the new Center is a modern facility for an ancient faith.  The Center provides needed space for social, cultural, educational, and religious activities.  A major design requirement was to design the facility in the Byzantine style to reflect the Parish’s proud heritage, legacy, and culture.  Sustainability, energy efficiency, and low maintenance were important design requirements as well.

Meyer Warehouse Automated Storage and Retrieval System

This project consists of a second phase 165,750 square foot automated pallet storage and retrieval system facility just under 100 feet tall. It is an alternate means building type due to the rack supported structure and specialized Early Suppression Fast Response (ESFR) system. The foundation system consisted of an 18 inch thick mat slab with double rebar mats that were placed by GPS locating to avoid the 56,000 bolts that were drilled into the foundation and attached to the racks. The skin consists of insulated metal panels supported from the perimeter racks. The steel roof structure spans between the racks and is covered with insulated metal roofing.

This facility connects to a first phase building previously completed by the same design team that is approximately 340,000 square feet and utilizes a pre-engineered interior structure to achieve 30 feet of clear height. The perimeter walls are composed of concrete tilt-up wall panels that are articulated with detailed reveal patterns and color variety to achieve a pedestrian scale facade in a massive distribution facility.

The building functions as the primary distribution facility for Farberware Cookware, and also provides a small amount of manufacturing functions. The second phase project also utilized a large storm water detention basis and rooftop solar panels.

Arco West Office Building

The Arco West Building is a 111,360 square foot two-story warm shell office building with a fully developed core. The 34' - 8" high tilt-up concrete building features prominent recessed entrances that break up the long East and West elevations. They serve to draw people into the lobby with a clean and contemporary textured concrete wall panel and a cantilevered painted steel canopy above the entry doors. The same wall treatment and protective canopy is repeated on the transverse elevations.

The core building mass extends 8' - 0" above the main building parapet to both mask and incorporate the rooftop mechanical screen into the form. The facade is further articulated with a gridded pattern of "V" reveals and 3" round recesses, and a series of square punched openings with lightly tinted glazing. On either side of the building entries, the concrete panels with canted edges and architectural reveals are visually enhanced with a variety of quality materials and colors. The complementary shades of tinted and spandrel glazing and horizontal rib formliner achieve the goal of breaking up the long walls with texture and color while providing a cohesive whole.

Unger Construction Company Office Building

This building is the corporate headquarters for Unger Construction Company, a Sacramento based general contractor established in 1926. The existing building formerly housed the LaFiesta Restaurant and Bakery. The front restaurant portion was removed, the bakery/warehouse portion was completely renovated, and new site and off-site frontage improvements were added.

The project design introduces a new two-story mass to the existing simple concrete tilt-up structure. This mass has two distinct design ideas: a corner entry "tower" and punctured wall planes. Both the existing and new building elements utilize an industrial aesthetic as an architecturally unifying concept.

Corner Tower: The corner of 9th and X streets is an important corner for the project, as this is the entry side and natural approach to the site from 9th Street to X Street to the parking lot drive. One of the tower legs vertically slopes at an angle is also utilized in other design elements of the project. The corner tower is clad with 1 1/2" deep ribbed metal paneling with a "Galvalume" (galvanized) finish. Horizontal butt glazed storefront wraps the corner on both floors with the upper floor being supported by an exposed painted red steel floor structure and a round column. A painted yellow metal cantilever trellis with galvanized metal screen panels terminates the top of the tower.

Client: Unger Construction Company

Punctured Wall Planes: The cement plaster walls of the addition have solids and voids, deep recessed grid patterned storefront, and horizontal metal awnings. A vertically oriented recessed area, 8" wide, mimics the 8" wide panel joints of the existing structure. The cement plaster is finished smooth with shallow "V" reveals in order to achieve a cast concrete look. The top 3' of the walls are a recessed cornice with a galvanized metal parapet cap. Tying into the trellis, horizontal painted yellow awnings with galvanized screen panels are located above the storefront windows.

The existing tilt-up walls which house the shop have 8" wide accentuated recessed panel joints and 2" wide perimeter steel angle corner embed reinforcement which define the panels as individual sections. This aesthetic is enhanced by painting these areas to match the galvanized (silver/gray) steel elements newly introduced in the two-story addition. The concrete panels are painted.

Sacramento County Office of Education
